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.

Things To Consider While Choosing An Eco-Friendly Hotel

Things To Consider While Choosing An Eco-Friendly Hotel

In recent years, we have had the opportunity to ponder our relationship with the environment. Consequently, we have come to recognize the importance of being more conscientious about our decisions, whether in our own homes or on holiday. To begin with, selecting an eco-friendly and sustainable accommodation is a good place to start when vacationing. If you want to learn more about how to do this, here are a few questions to consider asking.

What Are The Criteria’s To Qualify As An Eco-Friendly Hotel?

Certification for a hotel requires meeting specific standards in areas such as energy efficiency, water consumption, waste management policies, construction materials, design, community awareness, and sustainable site development. The most well-known certification in the hospitality industry is LEED (Leadership in Energy and Environmental Design). Other certificates, including EarthCheck, Green Key, Green Growth 2050, Forest Stewardship Council, The Rainforest Alliance, and Global Sustainable Tourism Council, are available.

Are Their Any Sustainability Reports?

Typically, these reports can be found on the company’s website. To determine how well the property was integrated into its environment, check for information on the amount of recycled or sustainable materials used in construction, such as certified wood, and whether the building is bioclimatic and outfitted with upcycled materials. You can also read about their carbon offset programs, staff training, community impact, energy consumption, linen reuse, recycling and waste management efforts, use of single-use plastics, and use of environmentally friendly cleaning products, among other things.

Is There A Waste Management And Recycling Plan In Place?

o ensure sustainability, it’s crucial to have a robust waste management system. Verify if the property composts food waste and learn about its efforts to reduce it. Inquire about their recycling practices, particularly their approach to plastic waste and how they manage any plastic waste generated.

What Is Their Plastic Policy?

Sustainable hotels opt for greener practices such as replacing plastic water bottles with reusable glass ones, some even having their bottling plant on-site. They are also transitioning from single-use shower toiletries to larger, refillable ones. Plastic straws and stirrers are being eliminated. When searching for eco-friendly accommodations, these are some factors to consider.

Do They Source Their Food Locally?

Check whether the hotel has a kitchen garden and follow a farm-to-table dining approach. Do they obtain their meat and eggs ethically? Is their menu created using seasonal produce? Lastly, do they adhere to sustainable seafood guidelines in their kitchen?

How Do They Save Water And Energy?

Inquire whether the establishment has adopted sustainable and energy-efficient measures, such as employing solar energy, LED lighting, and low-energy bulbs. Investigate the energy efficiency of their Heating, Ventilation and Air-Conditioning Systems (HVAC) system and other construction methods like insulation to decrease the demand for air conditioning, resulting in lower energy usage.

Tech and Ingenuity Supercharge a Sustainable Hotel

Tech and Ingenuity Supercharge a Sustainable Hotel

Automation, emissions analysis, upgraded technology, cloud computing, and artificial intelligence – these are just a handful of ways that businesses are promoting sustainability and reducing greenhouse gasses.

Hotel Marcel, based in New Haven. Conn., wants to lead the way when it comes to sustainability in the hospitality sector. With this goal in mind, a team of eco-conscious design, architecture, and technology experts have built the first net-zero hotel in the United States. Hotel Marcel is also one of only 10 LEED (Leadership in Energy and Environmental Design) Platinum-certified hotels in the country. Since its opening in 2022, the hotel has won countless awards related to its sustainability.

Hotel Marcel had a long life before becoming what it is today. It started life as the Armstrong Rubber Company Building in 1968. After a period of vacancy started in the late 1990s, the building was listed on the Connecticut Register of Historical Places in 2020 and then the National Register of Historical Places in 2021. Those designations added challenges for converting the building into an eco-friendly hotel. But with a steadfast vision by lead architect, developer, and owner Bruce Becker, along with partner Sinclair Digital, the hotel is now a model for those that follow.

 

Renovated Hotel Relies on Renewable Energy and Microgrid Technology

The details are impressive. The hotel reused as much of the existing infrastructure as possible during a full renovation. To meet its goal of generating all its power, the hotel relies on renewable solar power onsite to produce electricity for the entire property. Engineers also installed triple-glazed windows for efficient insulation; a heat pump system for hot water, space heating, and cooling; and elevators that generate their own electricity. Even the hotel’s laundry room runs on renewable electricity instead of natural gas.

While some of these measures, like coated windows and renewable building materials, were right in Becker’s wheelhouse, other, more technology-driven features were less so. Early in the process, Becker’s team installed an energy-efficient, DC-powered microgrid for the hotel’s converters, microcontrollers, and batteries. The localized, solar-powered DC microgrid runs independently of the main power grid and is powered by an Ageto ARC controller, which enables grid services and resilience sequencing.

Becker knew from learning about other sustainable hotel endeavors like the Sinclair Hotel of Fort Worth, Texas, that low-voltage Power over Ethernet (Poe) would make a significant difference. Unlike high voltage power, low voltage uses less electrical current and sends power and controls on the same cable, reducing the amount of infrastructure required and resulting in greater energy efficiency. These systems also operate at levels of as low as 24 volts, making them safer and installable without an electrician.

“Our engineers visited the Sinclair Hotel to see how PoE would work in a hotel setting,” Becker said. “We were very keen on using it for lighting and intelligent occupancy sensors and integrating it with mechanical blackout and sheer shades to create quiet, dark, and efficient rooms.”

 

Installing Lantronix Switches

At the same time, the Sinclair organization, now called Sinclair Digital, was expanding from its role as a traditional hotel developer to a consultant that partners with hotel developers to choose and implement PoE and other energy-saving technologies.

To enable PoE throughout Hotel Marcel, Sinclair Digital advised implementing Lantronix’s Smart Managed Gigabit PoE++ switch, which would support direct, high-voltage DC power and the latest PoE standard.

“After we did the Hotel Sinclair, we learned about Lantronix,” explained Sinclair Digital COO Hannah Walker. “We knew that it was increasing the power of its technology to 90 watts as opposed to 60 watts, which meant that if you had a network switch with 24 ports, you can now pass 90 watts per port, which gives you a lot of capacity.”

In keeping with the low-voltage theme, Sinclair also installed VoltServer Digital Electricity to power the Lantronix switches. This enables the switches to safely transport DC power at high wattages over long distances on Class 2 wiring. Digital Electricity is a low-voltage technology but has the power and distance capabilities of AC by splitting energy into packets and transmitting them every second by the hundreds from a transmitter to a receiver unit.

Racks of switches now populate four original electrical closets throughout the property, connected via fiber run between the floors. The switches power lighting and motorized window treatments and are integrated with the HVAC system. Becker said that the hotel’s 55 PoE++ switches have reduced lighting energy use by more than 30%.

 

Emergency Battery Backup System

Next up was comprehensive emergency battery backup for the entire hotel, including emergency lighting, elevators, and stairway pressurization. While emergency battery backup was a fairly new concept, Walker recommended going the extra mile because of its significant energy savings.

“All of the systems we use today in buildings are DC inside, so all renewable energy generates in DC,” Walker explained. “But every time you transport it in AC, you lose 15% of efficiency, and it adds up.”

The team chose a battery developed by Sinclair and LG Electronics. The massive Lithium Ion battery, designed to replace energy-hogging diesel generators, can be recharged with solar panels via a microgrid.

 

Grand Opening

With everything in place, the hotel opened last spring. Five-star ratings populate virtually every hotel booking and review site.

Becker ensured all systems were metered to help the hotel stay on track with its sustainability goals and LEED Platinum requirements. Both the Lantronix and VoltServer equipment have in-line metering capabilities and associated software. Becker and Walker will consider adding an energy monitoring system to better determine energy usage at all points and so guests can see how much energy their rooms save.

With its focus on sustainability practices, it’s unsurprising that Hotel Marcel continues to break barriers. Today, it’s on the cusp of being certified as the only Passive House hotel in the United States. Passive House, which focuses on building energy and efficiency, is a well-established standard in Europe and is gaining popularity in the U.S.

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.”
