Building with Cannabis: a Hempcrete Construction Hotel

Building with Cannabis: a Hempcrete Construction Hotel

Imagine a world where buildings are not only sustainable but also contribute to the fight against climate change; hempcrete construction might be the key. A world where construction materials come from renewable sources and have minimal environmental impact. In this post, we will explore the fascinating world of hempcrete construction and take a closer look at one groundbreaking project: the 12-story Hemp Hotel in South Africa, set to open its doors in 2024.

Why Hempcrete Construction?
Why choose hempcrete construction? Hempcrete is an eco-friendly alternative to traditional building materials. It is made from a mixture of the inner woody core of the hemp plant, known as the hurd, and a lime-based binder. This combination creates a lightweight material with excellent thermal insulation properties.

Hempcrete also has exceptional breathability, allowing moisture to pass through without causing damage or mold growth. This natural ventilation helps regulate indoor humidity levels and promotes healthier living environments.

Another advantage of hempcrete is its fire resistance. Due to the high content of mineralized cellulose fibers in the hemp stalks, it can withstand extreme temperatures more effectively than conventional building materials.

Best of all, hemp plants grow rapidly and require minimal water and pesticides compared to other crops used in construction materials. They absorb carbon dioxide during their growth cycle, and sequester it in the building, making hempcrete a carbon-negative choice for builders.

Choosing hempcrete construction means opting for an environmentally friendly solution that offers superior insulation properties, increased durability against fire hazards, improved indoor air quality due to breathability advantages, and supports sustainable agricultural practices.

The Hemp Hotel, South Africa 2024

We have seen many homes built with Hempcrete Construction, but not as many commercial buildings. For all the same reasons that hempcrete construction makes sense in residential applications, it may be even more beneficial in commercial applications. For example, a stunning 12-story hotel made entirely from hempcrete is becoming a reality in South Africa. Set to open its doors in 2024, the Hemp Hotel is set to revolutionize the hospitality industry with its sustainable and eco-friendly construction.

Located in Cape Town, this groundbreaking project, built by Hempcrete Construction experts Afrimat Hemp, aims to showcase the incredible versatility and durability of hempcrete as a building material. Hempcrete is made by mixing hemp fibers with lime and water, creating a lightweight yet incredibly strong substance that is both fire-resistant and highly insulating.

But what makes the Hemp Hotel truly unique is not just its construction materials – it’s also about promoting sustainability throughout every aspect of its design. From energy-efficient lighting systems to rainwater harvesting, this hotel will be an example of environmental consciousness.

Not only will guests have the opportunity to experience luxury accommodation while reducing their carbon footprint, but they’ll also gain insight into how we can build more sustainably for future generations.

Other Hempcrete Applications

Aside from residential and commercial buildings, hempcrete has a wide range of applications. Its versatility and eco-friendly nature make it a promising material for various projects.

  1. Infrastructure: Hempcrete can be used in the construction of bridges, roads, and other infrastructure projects. Its lightweight yet strong properties make it an ideal choice for these applications.
  2. Agricultural Structures: Greenhouses, barns, and storage facilities can also be built using hempcrete. The breathable nature of the material creates an optimal environment for plants while providing insulation against extreme temperatures.
  3. Public Spaces: Hempcrete’s sustainability can benefit parks, pavilions, and public restrooms. Not only does it offer durability and low maintenance requirements, but it also contributes to creating healthier environments for visitors.
  4. Artistic Installations: As a creative medium, hempcrete offers endless possibilities for artists and designers to explore their imagination. Sculptures, installations, or even furniture pieces made with this unique material add an element of sustainability to art exhibitions or public spaces.
  5. Retrofitting Existing Buildings: Instead of demolishing old structures that do not meet modern energy efficiency standards, retrofitting them with hempcrete can significantly improve their thermal performance while maintaining their historical value.

The potential uses of hempcrete are vast and exciting! As more people become aware of its benefits as a sustainable building material, we can expect to see further innovation in its application across different industries.

The rise of sustainable construction practices has paved the way for innovative solutions like hempcrete. The Hemp Hotel in South Africa showcases not only the beauty and functionality of this remarkable material but also serves as inspiration for future projects around the world. With more emphasis on environmentally conscious building methods, we can create spaces that benefit people and the planet alike.

Canada’s Sustainable Jobs Plan Will Become a Law Next Year

Canada’s Sustainable Jobs Plan Will Become a Law Next Year

Canada’s Sustainable Jobs Plan is intended to train workers for new roles in preparation for the future of a green economy. The government has presented a sustainable jobs bill that will provide the workforce needed for what is called a “just transition” to a new green economy. The country aims for a 40-45% reduction in emissions by 2030 and net zero by 2050.

Prime Minister Justin Trudeau hopes the Sustainable Jobs Plan will help attract billions of dollars in investment by creating a skilled clean energy workforce. The bill, which will become law early in 2024, will publish an action plan every five years to put in place measures to invest in the net-zero emissions economy and skills of the future. From 2025, the government plans to release a new sustainable jobs plan every five years.

This new legislation has been ongoing for over two years of consultations and conversations with provinces and territories, Indigenous Peoples, workers and unions, industry, environmental and civil society organizations and interested Canadians. Based on these conversations, the creation of the Sustainable Jobs Plan put forward ten concrete actions to advance the creation of sustainable jobs and support workers in every part of Canada. These actions include:

  1. Establish the sustainable jobs secretariat: This will ensure federal policies and program coordination among Government departments.
  1. Create a Sustainable Partnership Council: This council would advise the government on job creation and support workers.
  1. Develop economic strategies through the Regional Energy and Resource Tables: These tables will work with provincial and territorial governments, Indigenous groups and other partners to identify a set of concrete actions and develop economic strategies.
  1. Introduce a sustainable jobs stream under the Union Training and Innovation Program: This will provide workers with training, equipment and materials that meet industry standards and investments that support a low-carbon economy.
  1. Advanced funding for skills development for sustainable jobs: This will be achieved by working with universities, colleges, union training centres and employer groups to help workers succeed in a net-zero economy.
  1. Promote Indigenous-led solutions and a National Benefits-Sharing Framework: This will be achieved by continuously supporting Indigenous-owned clean energy projects across Canada.
  1. Improve labour market data collection, tracking and analysis: These improvements will help the council provide advice and identify new measures and actions that must be taken.
  1. Motivate investors and draw in industry leaders to support workers: The money will be used to support green infrastructure, clean technologies, climate action, and environmental protection.
  1. Collaborate and lead on the global stage: Canada is committed to ensuring that their best practices and lessons learned are shared globally.
  1. Establish legislation that ensures ongoing engagement and accountability: The overall goal is that all Canadians are involved in the decision-making process and that everyone adapts to new changes to help achieve our goals.

Canada’s Sustainable Jobs Plan will train people in jobs that are compatible with Canada’s path to a net-zero emissions and climate-resilient future. These include:

  • Clean energy: This includes jobs in solar, wind, hydro, and geothermal power generation, as well as energy efficiency and conservation.
  • Green infrastructure: This includes jobs in building and maintaining sustainable infrastructure, such as green roofs, rainwater harvesting systems, and electric vehicle charging stations.
  • Low-carbon transportation: This includes jobs in electric vehicle manufacturing, public transit, and active transportation (e.g., walking, biking, and rolling).
  • Sustainable agriculture: This includes jobs in organic farming, sustainable forestry, and aquaculture.
  • Recycling and waste management: This includes jobs in recycling, composting, and waste-to-energy.
  • Environmental monitoring and remediation: This includes jobs in monitoring air and water quality and cleaning up contaminated sites.

The Sustainable Jobs Plan will help to ensure Canada has the skilled workforce it needs to build a clean, healthy future for the country.

Think-tank Clean Energy Canada expects jobs in this sector will grow by 3.4% annually over the next decade, nearly four times faster than the Canadian average. With the commitment from the Canadian government to the Sustainable Jobs Plan, there is hope that the country can meet its environmental goals and that sustainable jobs will become the new normal across the country.

Creating more roles for women in sustainable construction

Creating more roles for women in sustainable construction

Since being elected as the first female President of Morocco Green Building Council, Wiam Samir has played a vital role promoting sustainable construction
In 2017, a study by the Organisation for Economic Cooperation and Development (OECD) claimed that under a quarter of women in the Middle East and North Africa are employed – one of the lowest rates in the world. At the same time, the WEF’s Global Gender Gap Report stated that women in the Middle East and North Africa will not see equal political representation with men until the year 2116.

However, the green building movement shows a promising future for women in leadership. Out of the nine Green Building Councils in the MENA region, six are led by women, each of whom dedicate their lives to overcoming the negative impacts of climate change in the Middle East and North Africa.

Wiam Samir, the first female President of Morocco Green Building Council from 2018-2020, is one of the women demonstrating exceptional leadership in the sustainability movement. Now, Samir is a Sustainability Consultant and Projects Manager for ALTO EKO, an environmental services company that strives to improve the sanitary quality and living comfort of spaces in Morocco.

“It is a truly great feeling to be part of the movement leveraging and leading the green sphere. Being an advocate for a topic that matters on different scales, from civil society to governmental entities, helps us realise the importance of our cause and double our efforts to make change happen,” said Wiam.

 

An advocate for a green and sustainable environment built on collaboration

After acquiring a degree in Engineering and Management Sciences from the Al Akhawayn University, Samir went on to gain experience as an intern for multiple manufacturing, supply chain and infrastructural companies. From there, she sought to gain a more permanent role as an engineer and consultant in environment, energy, and sustainable construction.

Between 2016-2018, Samir worked as a QHSE and LEED certification manager for the Casablanca Finance City Tower project. Designed to minimise ecological impact, the tower set precedents in building performance, scale, and technology throughout the MENA region.

In 2018, while serving as the first female President of Morocco’s Green Building Council, Samir decided to reinforce her engineering and technical skills with a Masters in Interdisciplinary Design for the Built Environment from Cambridge University. Since then, she has continued to collaborate with other sustainability pioneers to transform the MENA region’s construction landscape.

Speaking about her role at the 5th Edition Real-Estate Development Summit in Morocco, 2019, Samir said: “The targets of the project are to increase awareness and education, to achieve alignment between approach and certification schemes, and also to target the global market by showing examples of leadership. All of this started at COP21 for the Paris Agreement … the final objective is to limit global temperature rises below 1.5 degrees.”

A role model for female leaders pressing for progress around the world
Samir and other women leaders in the green building movement are not only addressing the issue of climate change; they’re also challenging gender inequality and fighting for equal opportunities in their countries.

Strict cultural rules in the MENA region mean that many women lack the same professional rights as men – including the freedom to pursue certain careers. Despite this, Samir’s dedication to collaboration and sustainable construction has given her a strong platform to demonstrate the important role women have to play in addressing environmental and social issues.

In 2022, Samir achieved WELL AP accreditation and received the community award from the International WELL Building Institute (IWBI). As Sustainability Consultant and Projects Manager for ALTO EKO, Samir continues to advocate for buildings, organisations and communities that support global health and promise a healthier future for all.

Balancing energy-efficiency and aesthetics: Large-scale Thermal Fenestration Systems

Balancing energy-efficiency and aesthetics: Large-scale Thermal Fenestration Systems

The total energy demand from buildings has risen dramatically in recent years. Driven by improved access in developing countries, greater ownership of energy-consuming devices and increasing urban densities, today it accounts for over one-third of global energy consumption and nearly 15% of direct CO2 emissions. As the climate crisis aggravates and its consequences are more visible than ever, the architecture and construction industry must respond accordingly. It must take responsibility for its environmental impact and give priority to reducing energy consumption, whether through design decisions, construction techniques or innovative products. The key lies, however, in not sacrificing aesthetics and comfort in the process.

The main areas of energy use in a building correspond to heating, ventilation and air conditioning, meaning that the role of building envelopes and fenestration is pivotal. Of course, windows and doors are essential for natural light, views, air flow and entries. With the right systems and materials, they can also provide insulation for improved temperature control, creating a barrier against cold weather during winter and blocking outdoor heat during summer months. In this way, energy-efficient thermal fenestration systems can open many possibilities in the path towards efficient, cost-effective spaces – although they have higher initial costs, these are offset in a few years thanks to substantial energy savings.

Optimal thermal performance and appealing visuals

Often, the Passive House Certification is set as the leading standard in ensuring resiliency in buildings. Projects designed according to its criteria perform 60-85% better on an energy consumption basis when compared to code compliant projects. But in many large-scale buildings with complex configurations, like multi-family housing projects, meeting this standard can be quite the challenge. And if we add to this the desire to create spaces that are appealing to live or work in, it is clear that design professionals face a complicated task.

Recognizing these needs, manufacturers of large format fenestration have focused on offering products that can be easily incorporated into a variety of building schemes. To be effective, these must follow a set of requirements: the glass selected in multi-pane units should restrict thermal heat flow or solar heat gain based on the building’s climate zone, the frames must be designed to control heat flow and thermal bridging within them, and the whole assembly needs to open easily to provide ventilation, yet still be able to close tightly to restrict unwanted air infiltration. All of this while responding to today’s visual demands, including expansive views, a connection to the surrounding landscape and a sleek, clean line contemporary style.

Recent innovations in engineering and design have taken these criteria into account to produce some appealing and efficient choices. For instance, CRL – the industry’s leading manufacturer and supplier of architectural glazing systems – has developed a series of large-scale fenestration products with a high thermal performance and outstanding functional (and aesthetic) qualities. We present some of them below, exploring their unique characteristics.

 

Sliding doors

Although oversized glass doors create striking visuals, they can also cause excessive heat loss or solar gain. With this in mind, CRL’s large-format sliding door systems provide daylight, uninterrupted views and maximum transparency while mitigating heat transfer using thermal breaks and insulating glass. Working with the rest of the building envelope to maintain comfortable interior temperatures, they place less strain on heating or cooling systems and foster user well-being. For example, the Palisades S100 Sliding Door, known for its elegant minimalistic look, is designed with ultra-slim panel rails and stiles, with panel heights up to 13 feet (approximately 3960 mm) and widths up to 7 feet (approximately 2130 mm). It features specialized seals designed to resist the entrance of air and water and is suitable for exterior applications with high loads, limits on deflection and heavy usage, exceeding in structural and thermal performance.

Bi-folding doors

Characterized by multiple hinged panels that stack to one side, the latest bi-folding glass door systems also offer advancements regarding thermal and aesthetic qualities. When opened, they provide seamless transitions that allow for ventilation and daylight; when closed, they deliver a streamlined look, prevent obstruction to preserve views, and seal up tightly to protect against water and air infiltration. In addition, these can feature thermally broken frames and 1-inch (2.5 cm) double pane insulating glass that together produce standard U-factors of 0.36, maintaining comfortable interior temperatures year-round and putting less strain on air conditioning systems. This applies to products like the Monterey S80 and the Palisades S90, which are able to meet the aesthetic and functional needs of today’s buildings with their sleek appearance, smooth movement and ability to reduce heat transfer.

Entrance doors

Entrance doors, for their part, can defy efficiency through air leaks – especially in large-scale buildings with constant circulation. In this sense, the Blumcraft Entice Series Doors were created to fulfill energy conservation requirements and simultaneously maintain an elegant appearance. The system has very slender vertical lines and the unique ability to support handle hardware on insulating glass with a “floating on air” aspect. It has also been engineered with thermally broken framing and cladding that lets the product achieve U-factors as low as 0.33. Altogether, Entice® enables architects to achieve an all-glass style while meeting increasingly stringent energy codes.

To develop complex buildings or multi-family projects that are healthy, appealing and achieve high levels of energy-saving performance, architects must adopt a series of strategies. This includes design decisions like enhancing the building envelope with the proper use of Weather-Resistant Barriers (WRBs) and incorporating effective Variable Refrigerant Flow (VRF) systems. Fenestration, on the other hand, can be addressed by selecting large-scale doors that provide high thermal performance without compromising comfort and beautiful visuals. If these strategies are combined, it is possible to contribute to the universal goal of net-zero architecture, promoting human and environmental well-being.

Public sector buildings to get £635m energy efficiency upgrade

Public sector buildings to get £635m energy efficiency upgrade

The Government has announced this morning (2 August), that the latest PSDS funding will be made available to enable organisations to invest in low-carbon solutions for public sector buildings like schools, hospitals and town halls.

Public sector organisations, such as local authorities, will be able to apply for a share of £625m allocation from September. The Government expects funding to be spent on solutions including heat pumps, double glazing and insulation to help lower energy costs through improved efficiency.

Public sector bodies and taxpayers are expected to save an average of £650m per year on energy bills over the next 15 years through the scheme. Already, more than 730 grants have been awarded across Phase 1 of the PSDS, which is helping to support around 30,000 green jobs.

Business and Energy Minister Lord Callanan said: “We are already delivering upgrades to hundreds of public buildings across England, making them cheaper to run and saving taxpayers millions of pounds each year.

“By helping even more public sector bodies ditch costly fossil fuels, we are taking an important step towards a more sustainable future while driving economic growth across the country and continuing to support tens of thousands of jobs.”

The scheme forms part of the Chancellor’s ‘Plan for Jobs 2020’ commitment to support the UK’s economic recovery and will reduce non-traded carbon emissions from the public sector by up to 0.1 MtCO2e/year and up to 0.5 MtCO2e over the next two Carbon Budgets. According to BEIS, this is equivalent to taking nearly 45,000 cars off the road.

The latest funding round is part of the £2.5bn set aside for government spending on upgrading public sector buildings between 2020 and 2025. The PSDS will help meet a goal of reducing emissions from public sector buildings by 75%, compared to 2017 levels, by 2037.

Those trying to gain access to funding from the PSDS have expressed annoyance at the amount of red tape that they needed to navigate, while also lamenting the lack of clarity on when funding windows will open and close. Some sustainability professionals operating within the sector claimed they didn’t have enough time or relevant information to submit a grant request. Indeed, smaller entities in the public sector may be put off by the time and expertise required to submit for funding.

The Net Zero Estate Playbook, has been published by the Cabinet Office to provide details on how to access the PSDS. It states that a fully developed “Green Book” for compliance should be included in the submission, but written by someone with Better Business Cases Practitioner qualifications.

Earlier this year, the National Audit Office (NAO) criticised the Government’s approach to accounting and reporting on public sector greenhouse gas emissions, citing multiple frameworks and a lack of ownership as reasons that create confusion for professionals in the sector.

The new NAO report finds that while central government departments are reporting decent progress on decarbonisation a “patchy” and “inconsistent” approach to reporting and accounting is creating confusion in the sector.

 

Beyond net-zero in the public sector

The public sector represents a critical piece of the UK’s net-zero puzzle. From local government to hospitals, schools and social housing providers – a significant amount of investment and work is required to cut emissions and embrace clean technologies. But beyond simply ‘reducing’, public sector organisations also have a key role to play in enhancing the environmental and social sustainability of the communities they serve.

This report aims to highlight the optimism in the sector in not only playing a key role in reaching net-zero, but also contributing to a “net-positive” approach to society, the economy and the planet.

What does true sustainability look like in the hotel industry?

What does true sustainability look like in the hotel industry?

In a bid to become more environmentally sustainable, Raffles Hotel Singapore has reimagined its signature drink: the Singapore Sling, a fruity gin-based cocktail dating back to the 1900s.

In 2018, the 5-star ultra luxury hotel partnered with spirits company Proof & Company’s ecoSPIRITS programme to transform the drink’s life cycle. Using a closed-loop distribution system, they were able to eliminate several thousand kilograms of packaging waste annually. Furthermore, for every 25 Singapore Slings served, a native tree is planted in Kalimantan and Sumatran rainforests.

According to consultancy firm Deloitte’s calculations, every glass of Singapore Sling now emits 200 fewer grams of carbon dioxide than before.

Raffles Hotel is not the only establishment raising its sustainability game. In 2019, Marriott International, the world’s largest hotel chain, phased out single-use plastic toiletry bottles in favour of larger pump dispenser bottles. Meanwhile, Hilton committed to reducing food waste by 50 per cent by 2030.

Many of these initiatives are driven by consumer demand for more sustainable accommodation, which has skyrocketed in recent years. According to Booking.com’s 2021 Sustainable Travel Report, 81 per cent of travellers said that they want to stay in sustainable accommodation in the upcoming year, a significant jump from 62 per cent in 2016.

Local hospitality and tourism institutions are also putting greater pressure on hotels to decarbonise. In March 2022, the Singapore Hotel Association (SHA) and Singapore Tourism Board (STB) launched a Hotel Sustainability Roadmap which urged establishments to reduce emissions by 2030 and reach net-zero emissions by 2050.

“There’s just more pressure all around now,” said Eric Ricaurte, founder of hospitality consulting firm Greenview. “While previously we only saw incremental changes like reusing linen towels, hotels are now also paying attention to issues like energy and carbon. We’re seeing sustainability appear on the radars of hotels everywhere.”

But amidst hotels’ greater focus on sustainability, how many of these changes are greenwashing — initiatives designed to mislead guests and present a false environmentally responsible public image?

 

There is some great work happening, but there’s a lot of PR-driven hot air too.

– Tim Williamson, customer director, Responsible Travel

 

Greenwashing, or genuine change?

There’s a mix of both, says Tim Williamson, customer director of Responsible Travel, an activist company seeking to design conscious trips.

“There is some great work happening, but there’s a lot of PR-driven hot air too,” said Williamson. “For example, while some hotels have set net zero targets, they may ‘hide behind’ carbon offsetting to reach these goals, which is not the same as a real reduction in their emissions.”

According to Ricaurte, another form of greenwashing is when hotels offer an asymmetrical representation of their environmental impact. He pointed to some hotels which may have removed plastic straws, but still use large amounts of plastic in other aspects of their operations.

To identify hotels that genuinely care about sustainability, Ricaurte said guests could consider whether the hotel pays attention to both lower-hanging fruit — like providing plant-based options on their restaurant menus — as well as formal certifications.

There is currently a growing list of globally-recognised sustainability certifications for the hotel sector, including the Green Key eco-label, Green Globe, as well as Booking.com’s recently launched Travel Sustainable Badge. But Williamson says not all certifications are created equally. Less credible schemes may only require hotels to undertake a self-assessment, rather than be evaluated by an independent third party.

“There is also the issue of what is relevant,” said Williamson. “Reducing water consumption may be less of a priority for a hotel in Scotland than for a hotel in a drought-ridden area of southern Spain, but many green certification schemes don’t make this distinction. This means businesses may have a green badge but still be failing to address the challenges most pressing in their local area.”

Rather than relying solely on certifications, Williamson instead encouraged consumers to “look behind the labels” and ask for written policies and specific examples.

“What percentage of employees are local, and do they receive a fair wage? How much of the produce is sourced from local suppliers? What are they doing to help protect and restore nature, and how are they cutting food waste? Don’t take all labels at face value,” he said.

 

Transparency trade-offs

While green marketing is on the rise, not all hotels have opted to integrate sustainability into their branding. Raffles Hotel Singapore, for example, features little about sustainability on its website.

“We think that sustainability and saving the planet shouldn’t be used as marketing highlights,” explained general manager Christian Westbeld. “They should be something that you really live by. We all have to do the right thing.”

Westbeld says that when the hotel closed its doors for extensive restoration from December 2017 to August 2019, sustainability was high on the agenda. The environmental footprint was taken into consideration in all aspects, from the plumbing systems to kitchen equipment, and even the linen in each guest suite.

“For example, the windows in each suite are now double glazed to better retain cold temperatures, therefore encouraging guests to use air-conditioning for shorter periods of time,” said Westbeld.

However, most of this information is not highlighted to travellers on Raffles Hotel’s marketing platforms.

Dr Victor Nian, Chief Executive Officer of Singapore-based think tank Centre for Strategic Energy and Resources, said such an approach eliminates the issue of greenwashing entirely. However, he cautioned that transparency is also very important.

“If a hotel publishes a sustainability report on their website, it’s often a positive sign that they are trying to do something. It also gives you a chance to compare sustainability among different hotels,” he said, adding that such reports are often endorsed by a verified body.

“But if they don’t publish anything, people won’t know what they are doing at all,” he said.

Laura Houldsworth, Asia Pacific managing director at Booking.com, an online travel agency, shared similar views: “We think hotels should be encouraged to share their sustainability initiatives. We believe in educating travellers and empowering them with the right knowledge, so they know how to avoid these pitfalls.”

 

An uphill battle

Westbeld admits it can be difficult to prioritise sustainability as an ultra luxury destination.

“We will never compromise on service standards and guest experience,” he said. “For example, we won’t openly recommend guests not to change sheets. It is a guest’s choice — they can approach us and say they only want to change it every other day. But we don’t compromise on hygiene and comfort.”

Hotels also face constraints that they may not be able to immediately address.

According to Ricaurte, one of the biggest challenges in reducing emissions is the design of the building itself, since the key moments when those design decisions are made may not have factored in sustainability. This results in the hotel lagging behind on building sustainability standards.

Hotels are often also constrained by their location and local energy grid.

“In Singapore, if the electricity grid is mostly powered by fossil fuels, there’s very little hotels can do to decarbonise that,” said Dr Nian.

While there are still ways hotels can reduce their energy consumption, such as improving the air-conditioning efficiency or exploring rooftop solar, Dr Nian said that these measures often have limited impact in driving down absolute emissions. Hotels may also be reluctant to implement these changes due to cost barriers, he added.

Ultimately, as demand for sustainability grows, the notion of luxury may need to be redefined for travellers and hoteliers alike to meet their sustainability goals, says Responsible Travel’s Williamson.

“Luxury doesn’t have to be all about air-con and all-inclusives. It can also be about bespoke, authentic experiences and great personal service,” he said. “It could be a small, locally-owned hotel with its own vegetable garden and hosts who know the best off-the-beaten-track spots for hiking, food and culture. Or a small ship cruise which really gets you into the nooks and crannies of a place, instead of a colossal liner.”

“High-value, low-impact tourism can benefit local communities and important conservation work too. Everyone wins.”

Big data, low carbon: how data centres innovate for sustainability

Big data, low carbon: how data centres innovate for sustainability

Data centres are well-known for being energy guzzlers because of the growth of digital demand. Worldwide, they consume an estimated 200 terawatt hours a year (TWh/yr), or nearly 1 per cent of global electricity demand.

That said, the energy consumption of data centres has not grown at the exponential rate of Internet traffic. This is due to the huge strides made in energy efficiency in data centres. Improvements in the efficiency of servers, storage devices and data centre infrastructure, as well as the move away from small data centres to larger cloud and hyperscale data centres, have all helped to limit the growth of electricity demand.

According to figures from a report by the International Energy Agency (IEA), from 2010 to 2020, the number of internet users worldwide has doubled and global internet traffic has expanded 15-fold. But global data centre energy use has been flat since 2015, at about 200 TWh/yr.

Globally, leading data centre operators have committed to carbon neutrality and science-based targets for emissions reduction by 2030. To achieve these goals, they have partnered with technology companies to develop ways of reducing energy consumption at all levels of operation – from direct-to-chip cooling to providing on-site prime power through alternative energy fuel cells.

 

New cooling solutions

One of the main areas of innovation is developing new solutions to cool data centres more efficiently as their capacity grows. Typically, cooling accounts for a large proportion of overall power consumption. Estimates from 2021 suggest that the figure ranges from 30 to 37 per cent.

Air cooling has been widely adopted in data centres since their inception. The basic principle of such systems involves circulating cold air around the hardware to dissipate heat.

 

More high power-density racks of up to 50kW are being deployed in data centres, such as those at Equinix’s International Business Exchange (IBX) data centres around the world. Source: Equinix.

 

But air cooling systems are struggling to keep up with the increases in the power density of racks. Thanks to new generations of central processing units (CPUs), rack power requirements have moved from below 20 kilowatts (kW) to up to 40 or 50 kW today, easily.

Air cooling systems have evolved to address higher densities, but there is a point at which air just does not have the thermal transfer properties to do so in an efficient manner. This has caused organisations to look into liquid cooling, as water and other fluids are up to 3,000 times more efficient in transferring heat than air.

Liquid cooling is available in a variety of configurations that use different technologies, including rear door heat exchangers and direct-to-chip cooling.

Rear door heat exchangers is the more mature technology, where a liquid-filled coil is mounted in place of the rear door of the rack. As server fans move heated air through the rack, the coil absorbs the heat before the air enters the data centre.

Direct-to-chip cooling integrates the cooling system directly into the computer’s chassis. A liquid coolant is brought via tubes directly to the chip, where it absorbs heat and removes it from the data hall. The warm liquid is then circulated to a cooling device or heat exchange.

One of the world’s largest data centre providers, Equinix, for example, is developing a new direct-to-chip cooling technology at their Co-Innovation Facility (CIF) located in the Washington DC area. Developed in collaboration with Zutacore, the system introduces a cooling fluid to an evaporator overlying the CPU to absorb heat directly, which in turn causes the liquid to evaporate and produce a constant temperature over the CPU.

 

Hotter temperatures

Some operators are challenging the thinking that data centres should be operated at low temperatures of 20 to 22 degrees celsius. There is evidence to support the running of data centres ‘hot’, i.e., increasing their temperature by 1 or 2 degrees Celsius, which improves efficiency without any significant sacrifices in system reliability.

In Singapore, the Infocomm Media Development Authority has been trialing the world’s first ‘tropical data centre’, to test if data centres can function optimally at temperatures of up to 38 degrees Celsius and ambient humidity up to or exceeding 90 per cent.

Running with simulated data, the trial would test how data servers react under various situations, such as peak surges or while transferring data, and in conditions such as with no temperature or humidity controls.

 

Using digital resources and analytics to optimise energy usage

Smart solutions monitoring energy consumption patterns allow data centres to configure the optimal use of their resources, as well as to identify and diagnose equipment problems and take steps to fix them. Software powered by artificial intelligence (AI) can also assist companies to better manage their infrastructure and maximise the utilisation of their CPUs.

In an interview with Fortune, Equinix’s chief executive Charles Meyer explained that AI is used in the company’s data centres to “anticipate where power needs to be applied, how cooling… needs to be done to improve the power usage efficiency of the facility overall”.

 

Using on-site lower-carbon energy sources

New cooling solutions and digital resources are offsetting the energy consumption from increasing data centre services. However, there remains the question of energy supply to the facility overall.

A totally carbon-free solution would involve locating a data centre beside a wind- or solar-generated renewable energy source, or purchasing 100 per cent green energy from the grid. But these may not always be feasible solutions. In Singapore, for instance, space constraints limit the use of solar energy, and wind conditions are not sufficient for wind power.

Alternatives include the use of fuel cells for primary power supply at data centres. Fuel cells generate power through electrochemical reactions using natural gas, biogas or LPG. Testing by Equinix at CIF indicates they are 20 to 40 per cent cleaner than gas-powered electricity generation.

When fuel cells are set up near data centres, there are even greater efficiencies. The generated electricity has less distance to travel and hence less energy is lost in the transmission process.

Equinix has deployed fuel cells at 15 of its facilities, including the carrier-neutral SV11 opened in San Jose in 2021, which utilises 4 megawatts (MW) of fuel cells for primary power production on site and can scale up to 20 MW of fuel cells.

Equinix is also part of a consortium of seven companies (including InfraPrime, RISE, Snam, SOLIDpower, TEC4FUELS and Vertiv) which launched the Eco Edge Prime Power (E2P2) project. E2P2 is exploring the integration of fuel cells with uninterruptible power supply technology and lithium-ion batteries to provide resilient and low-carbon primary power to data centres.

This work will also pave the way to transition from natural gas to green hydrogen (hydrogen produced using renewable energy) in fuel cells. Such advances are a step change towards sustainability where green hydrogen is available.

 

A holistic approach

Energy efficiency is crucial in determining future emissions in an industry that will continue growing in response to digitalisation and data consumption.

Besides energy efficiency, major data centre operators are interested in holistic sustainability gains that minimise carbon emissions. They consider how sustainable their supply chains are, total resource use and the company’s whole carbon footprint such as the embodied carbon in building materials.

Equinix, for example, has adopted a global climate-neutral goal by 2030 and has embedded decarbonisation actions across its business and supply chain.

Jason Plamondon, Equinix’s regional manager for sustainability in Asia-Pacific, says that the company is “well on (its) way to meeting (its) climate commitments, with over 95 per cent renewable coverage for (its) portfolio in FY21, maintaining over 90 per cent for the fourth consecutive year”.

He adds: “As the world’s digital infrastructure company, we have the responsibility to harness the power of technology to create a more accessible, equitable and sustainable future. Our Future First sustainability approach includes continuing to innovate and develop new technologies that contribute to protecting our planet.”

Singapore introduces framework for sovereign green bonds ahead of inaugural issuance

Singapore introduces framework for sovereign green bonds ahead of inaugural issuance

Singapore on Thursday (Jun 9) published the governance framework for sovereign green bonds, ahead of the first such issuance expected in the next few months.

This comes as Singapore moves to develop the green finance market and make green finance a driving force for sustainability.

The Singapore Green Bond Framework sets out guidelines for public sector green bond issuances under the Significant Infrastructure Government Loan Act 2021 (SINGA), said the Ministry of Finance (MOF) and the Monetary Authority of Singapore (MAS) in a media release.

It covers the Government’s intended use of green bond proceeds, governance structure to evaluate and select eligible projects, operational approach to manage green bond proceeds, and commitment to post-issuance allocation and impact reporting.

In addition to providing the foundation for green bonds issued by the Government, the framework will also serve as a reference for statutory boards that issue their own green bonds.

The key principles considered in the development of the framework were alignment with internationally recognised market principles and standards; stringent governance and oversight of project selection and allocation of proceeds; and technical screening to evaluate and identify green projects, MOF and MAS said.

 

 

Eligible expenditures

At Budget 2022, Finance Minister Lawrence Wong announced that the Government would issue S$35 billion of green bonds by 2030 to fund public sector green infrastructure projects.

Proceeds from these bonds, which will be issued under the new framework, will be used to finance costs associated with the Singapore Green Plan 2030, MOF and MAS said.

In turn, the eligible green projects are expected to facilitate the transition to a low-carbon economy in Singapore and contribute to the climate-related and environmental goals set out by the Singapore Government.

The categories of “eligible green expenditures” are:

  • Renewable energy
  • Energy efficiency
  • Green building
  • Clean transportation
  • Sustainable water and wastewater management
  • Pollution prevention, control and circular economy
  • Climate change adaptation
  • Biodiversity conservation and sustainable management of natural resources and land use

The workplace of the future: smart, sustainable, holistic

The workplace of the future: smart, sustainable, holistic

The workplace as we know it has evolved dramatically during the Covid-19 pandemic, expanding into our homes and complex digital-physical spaces. As organisations and their employees continue to navigate hybrid working arrangements this year, how can technology help to shape green and conducive workplaces of the future?

Many new innovations are aimed at helping workplaces save energy. While energy efficiency may not be the snazziest of climate solutions, it remains a potent and cost-effective way to slash emissions without major reworks of existing infrastructure. The International Energy Agency (IEA) has projected that low-cost measures, such as better ventilation and LED lighting, if implemented globally, could slash 3.5 gigatonnes worth of carbon emissions a year.

The savings would amount to 40 per cent of the emissions that need to be abated to limit global warming to 2 degrees Celsius. With the increased focus on climate mitigation, energy efficiency solutions for the built sector is now a US$340 billion market globally that is set to grow by over 8 per cent through 2027.

In addition, in Singapore, energy efficiency incentives like the Green Mark Incentive Scheme are encouraging companies to pursue smart, sustainable and predictive solutions in the workplace. Companies are paying closer attention to their carbon footprint to support sustainability goals, and this requires more tools to monitor and optimise utilities consumption.

These tools usually come in the form of building intelligence systems, such as SP Digital’s GET Control. The system uses AI and IoT to optimise and regulate air-conditioning and maximise energy efficiency in real-time, based on changes in occupancy, current weather conditions and forecast data. The smart damper system, for example, divides large open-plan office spaces into micro-zones to enable better air-flow distribution and control. With predictive intelligence working together with all the sensors and smart dampers, data is sent wirelessly to a central control unit that recommends and adjusts the dampers dynamically such that the desired temperatures are met, making the office energy efficient and comfortable.

Clement Cheong, SP Digital’s vice president of sales and customer operations, says that GET Control responds to the needs of corporate real estate owners and commercial landlords in Singapore.

“Landlords are seeing more occupants coming into work and at different times,” he says. “They need to adapt their buildings and systems to cope with this change dynamically. For example, they do not need as much cooling or fresh air supply at non-peak or low occupancy periods.”

Moreover, he adds that the pandemic has also made employees even more conscious of indoor environmental quality. “They want to have visibility into IAQ (Indoor Air Quality) and the building’s measures to monitor and improve IAQ. Even though occupants may spend less time in the office, they want a better, healthier indoor experience.”

He explains that currently, building owners or tenants have limited visibility into indoor air quality in offices and limited ability to intelligently control it. Traditional air side control and management technologies tend to be “reactive”, that is, facility managers make adjustments when occupants complain of any indoor thermal discomfort. Because such technologies do not take into account dynamic changes in ambient temperatures, they are not as energy efficient as a system with real-time tracking capabilities like GET Control.

He shares a case study from an educational institution in Singapore, where facility managers were faced with frequent occupant complaints about hot and cold spots in the office. Besides the fact that facility managers had to make time-consuming manual adjustments, the building’s cooling efficiency was poor, resulting in high energy use and carbon emissions. When SP Digital’s GET Control was deployed, the site saw more than 30 per cent airside cooling energy savings, enhanced thermal comfort and indoor air quality for employees, and improved operations and productivity.

On a larger scale, some multinational corporations are leading the way in greening their offices, and their examples might provide insights into the future of the sustainable workplace. One of them is Meta, which operates the social media platform Facebook and aims to achieve a 50 per cent reduction in carbon by 2030. At its 260,000 square-feet office in Singapore, spread over four floors at Marina One Tower, this target has translated into environmental control systems that use the latest in automated sensor technology, which can optimise even the smallest indicators of energy efficiency. Numerous sensors are in place to measure temperature, air, light and motion open spaces, meeting rooms and lifts.

Apart from office management, Meta Singapore also uses technology to assist employees to adopt carbon reducing behaviours, and, while in the workplace, to holistically analyse their carbon footprint across the product supply chain, recycling, water and waste management.

Looking ahead globally, the journey to make buildings more sustainable will be a long one. Currently, the built environment is responsible for nearly 40 per cent of all greenhouse gas emissions in the world. According to a report by the International Energy Agency (IEA), the 2020 pandemic caused a drop in the buildings sector carbon emissions, followed by a moderate rebound in 2021, but buildings are not on track to achieve carbon neutrality by 2050.

In Singapore, energy efficiency remains a core tenet of the city-state’s decarbonisation pathway, even as longer-term solutions such as carbon capture and clean energy imports are being considered for the next few decades. Power generation firms are provided subsidies to upgrade their turbines and software; a similar fund is in place for building owners to buy more efficient air-conditioning systems and install motion sensors that automatically switch off appliances when not needed. Buildings contribute close to 15 per cent of Singapore’s national emissions — the high fraction resulting from the almost complete urbanisation of the island-state.

As part of its efforts to reach net-zero emissions around 2050, the government wants 80 per cent of buildings in Singapore – both old and new – to adopt energy efficiency measures by 2030, up from 50 per cent today.

There is growing awareness among businesses that greening their offices makes economic and environmental sense. The Singapore Building and Construction Authority’s Green Mark Incentive for Existing Buildings – a $100 million fund started to co-sponsor the adoption of energy-efficient technologies in existing buildings – has been fully committed, as has a separate $50 million fund which does the same for small and medium enterprises.

This suggests that more landlords in Singapore understand that the initial outlays of such green investments may be high, but returns in the long run justify the cost, given the changes in expectations of workplace experience, energy efficiency and sustainability in post-pandemic times.

The key to eco architecture is green space and floods of sunlight

The key to eco architecture is green space and floods of sunlight

Architects in Australia have built an ‘eco-house’ with estimated bills of just €300 a year. BENT Architecture specialises in sustainable buildings, embracing passive solar design techniques to minimise both energy bills and the environmental impact of the spaces.

The Olinda House is a bespoke eco-friendly design for the owners, in Victoria, Australia, who wanted a space which would sit harmoniously within the landscape and work with nature, rather than against it.

“Like all our projects, the Olinda House embraces the sun and uses passive solar design techniques to ensure the home is comfortable and efficient, year-round,” explains BENT Architecture director Paul Porjazoski.

 

“We can no longer afford to see the built environment as being separate to the natural world.”
Paul Porjazoski , Director, BENT Architecture

 

“The home is long and narrow, stretching from east to west to maximise the opportunity to capture northern light – which is perfect for the southern hemisphere! And windows on opposite sides of the home capture cooling breezes. This keeps the interior naturally warmer in winter and cooler in summer.”

 

By intelligently incorporating sunlight into the designs, the house is both economical and stunningly lit TATJANA PLITT

 

The design uses solar panels on the roof to meet any energy needs, meaning the property is not just aesthetically pleasing, but low-energy too with an estimated annual power bill of just €300.

“Olinda House celebrates and enhances the spectacular natural landscape of its site,” Porjazoski says, which is something at the heart of BENT Architecture’s ethos. Things like sunlight and wind are seen as fundamental parts of the design, as Porjazoski and his team seek to strike a balance between structures and nature, “we can no longer afford to see the built environment as being separate to the natural world.”

We must “embrace in a celebration of the site, where the position of the sun and prevailing breezes are treated as building materials equivalent to the bricks and mortar of the building,” he says.

 

Is sustainability affordable?

The team at BENT Architecture has seen that the overwhelming majority of their residential clients are keen to implement sustainable design principles, as they look to minimise their environmental footprint. But what about the people who can’t afford a bespoke housing design?

 

“Buildings should work for us, not against us, to create a meaningful link between us and the outside world.” TATJANA PLITT

 

Porjazoski argues that the fundamentals of sustainability shouldn’t require additional expense. By incorporating sunlight and prevailing wind into a project, an architect can minimise energy consumption without having to spend anything extra. “These gifts from nature are free, and we should use them,” he explains, our buildings should “work for us, not against us, to create a meaningful link between us and the outside world.”

 

The fundamentals of sustainability shouldn’t require additional expense.

 

Unfortunately, these aren’t necessarily principles which are being considered by every developer or architect, especially when it comes to mass-production of houses in Europe to meet rising demands.

However, one major developer in the UK for first-time buyers, Countryside Properties, does incorporate some green initiatives into their designs. While they aren’t harnessing nature in the same way as BENT Architecture, because the majority of their properties are large-scale developments, it is still something they are considering.

Countryside Properties was the first construction company to open its own timber frame facility, which helps make a house far cheaper to heat, thus minimising the carbon footprint. Associate Director Andrew Fox says that the frame facility is an asset in many regards, “but the biggest benefit is how much it reduces our environmental impact.”

The houses have other efficiency measures in place too, such as water-saving fixtures and low energy lighting, which are estimated to save buyers up to £1,723 (€1,970) a year on energy costs, when compared to a second-hand property from the 1930s.

While the work being done with Countryside’s properties is certainly a step in the right direction, we still seem to be a long way off eco-homes like the Olinda House being the go-to for first-time buyers.

 

Green non-residential spaces are on the rise

Although mass-produced residential spaces are yet to incorporate the techniques of BENT Architecture, it is becoming de rigueur in community spaces. This means the benefits of sustainable building design are being increasingly opened up to the wider public, not just those who can afford to commission a bespoke design.

 

Lister House Health Centre in Harlow, UK, uses an environmentally-friendly design to create a welcoming space CAMM Architects

 

The Lister House Health Centre in Harlow, UK, is an award-winning design by Paul Young at CAMM Architects. Because the purpose of the space is to be one of healing and wellness, Young harnessed the natural environment to create a more positive experience for patients.

 

Architects should always be aware of the need to use the environment: it’s in our DNA.”
Paul Young Architect, CAMM Architects

 

“We brought light and air into the centre of the building,” says Young, “as we aimed to make it a cheerful and uplifting experience. Using light colours and rooflights to connect the internal rooms with the sky: we wanted to make people feel well just by entering the building, which is something possible by using sunlight in a space.”

For Young, sustainability should be at the heart of every architect’s practice, no matter if it’s a mass housing development, or for a commissioned, luxury property. “I believe architects should always be aware of the need to use the environment: it’s in our DNA,” he says.
