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.

‘Cool’ roofs, cooler designs as the building industry embraces energy sustainability

‘Cool’ roofs, cooler designs as the building industry embraces energy sustainability

The southwestern New Mexico town of Columbus, site of a 1916 raid by Pancho Villa, is now home to a border entry center that is powered by the sun and landscaped with recycled concrete “sponges” that harvest rainwater.

An apartment complex in Los Angeles created expressly for formerly homeless men and women has features that maximize natural light and airflow, a roof designed to minimize heat inside the units during summer, and a rooftop garden that attracts migratory birds.

And across the country in Brooklyn, e-commerce giant Etsy established its headquarters in a 200,000-square-foot building that previously housed a printing press for Jehovah’s Witnesses, then renovated and retrofitted so it is powered by renewable energy.

All three sites, spotlighted last year by the American Institute of Architects in its top-10 list of sustainable projects, reflect the expansive reach of “low-energy” design strategies and the building industry’s embrace of sustainability as a de facto imperative. They’re part of a remarkable evolution, one that could prove crucial since the building sector globally accounts for at least 40 percent of the world’s emissions of carbon dioxide — far more than transportation sources.

Some advocates think the U.S. sector can achieve net-zero emissions within 20 years, a decade ahead of President Biden’s net-zero goal for the country. The administration’s initiative includes new codes and efficiency standards for homes, appliances and commercial buildings — and a clean electric grid. Dozens of cities and states are moving forward with their own measures.

“Decarbonization of the sector is inevitable,” according to Edward Mazria, founder of Architecture 2030, a nonprofit organization based in Santa Fe, N.M., that aims to reconfigure the built environment as part of the solution to global warming.

The past several years served as an “urgent call to action,” he thinks, with devastating storms and wildfires on several continents, profoundly diminished Arctic sea ice, and the highest global temperatures in recorded history. “It’s not a matter of if we transition to renewables, but whether it will be fast and well-orchestrated enough to avert irreversible climate chaos.”

Since the nation’s building stock started its rapid expansion more than two centuries ago, the energy all that construction consumed and the greenhouse gases it then emitted have only increased — dramatically so.

But the numbers began changing in 2005 as building efficiency gained traction. Despite the building sector producing an additional 50 billion square feet in the past 15 years — housing, office parks, skyscrapers, hospitals, factories, schools, shopping centers and other commercial projects — its energy consumption actually dropped 5 percent and emissions fell 30 percent, data from the U.S. Energy Information Administration show.

In Mazria’s view, building “green” is not a hard sell, especially given cost-effective design approaches that can produce high-performance buildings with little to no energy consumption or emissions. Strategies include considering a structure’s shape and orientation on a site, adding “cool” roofs that reflect more sunlight and absorb less heat, and more.

“In 50 years, I’ve never heard a client say they want an inefficient building that costs more to operate and damages the environment,” Mazria said.

Sierra Atilano echoes his sentiment in Los Angeles. She is chief real estate and investment officer for Skid Row Housing Trust, which commissioned the apartment complex in the city’s MacArthur Park neighborhood where formerly homeless people, some of them veterans, now live. Passive design approaches such as the building’s exposure to prevailing winds make it 50 percent more energy efficient than conventionally designed counterparts, according to the architectural firm Brooks + Scarpa.

“Adding sustainability is a no-brainer in developing equitable housing,” Atilano said. “Affordable housing should be designed on par with market rate housing; it’s important not just for the residents but for the community at large — and the environment.”

While new construction is the obvious target for low-energy design, the American Institute of Architects also emphasizes the need to adapt and retrofit existing buildings — an especially salient point given how the pandemic has depressed demand for commercial and office space. The curriculums at the country’s leading architecture schools reflect this reality and the opportunities it offers.

“The median age of commercial buildings in the U.S. is 36, with almost a third of commercial buildings over 50 years old,” noted Erica Cochran Hameen, co-director for the Center for Building Performance and Diagnostics at Carnegie Mellon University’s School of Architecture. “Knowing most of our students after graduation will work on projects that involve an existing building, it is critical to educate them on advanced retrofit and building upgrade design strategies and technologies.”

The results increasingly are quantified. There are benchmarking policies and performance metrics. The 2021 International Energy Conservation Code set new minimum efficiency standards for myriad construction elements, part of “lifecycle accountability” for a building. Jurisdictions that adopt the code’s zero-carbon approach “have an avenue to ask for annual performance data and measure on-site energy generation and off-site energy procurement,” explained Anica Landreneau, sustainable design director for the global firm HOK.

In fact, cities from Portland, Ore., to Portland, Maine, now require such data, and Landreneau sees that as a positive. “Both benchmarking and performance standards trigger retrofits, which create domestic jobs while reducing carbon emissions, increasing energy security and improving quality of life for building occupants,” she said.

Yet home builders have a different take on regulatory mandates, instead supporting “voluntary, above-code programs,” Jaclyn Toole of the National Home Builders Association said. “Maintaining housing affordability must be the cornerstone to any efforts to create greener and more efficient homes.”

And fossil-fuel interests continue to oppose proposals to eliminate natural gas equipment in buildings, successfully pushing legislation in at least 12 states to bar any exclusion. “Policies that would force people to replace natural gas appliances with electric ones could be burdensome to consumers and the economy, have profound impacts and costs on the electric sector and be a very costly approach for a relatively small reduction in emissions,” said Jake Rubin, a spokesman for the American Gas Association.

Environmentalists counter Rubin’s argument by emphasizing the magnitude of what energy improvements achieve in cost savings and decreased emissions — billions of metric tons in this country alone.

“Efforts by gas utilities to fight [building] electrification represent one of the biggest threats facing the planet now,” said Rachel Golden of the Sierra Club, citing a major U.N. report on methane. “Every time a new home or building is connected to the gas system … we’re expanding the use of gas.”

A clear shift seems underway, however. In California, advocates are working to get gas out of new construction through the state energy code. More than 40 cities and counties have already passed measures requiring or encouraging that fossil fuel energy be phased out in favor of building electrification, and the Sierra Club counts more than 50 other jurisdictions in the state that are weighing such policies.

Elsewhere are similar signs of transformation. Burlington, Vt., which became the nation’s first city to go all-renewable after opening a hydroelectric facility in 2014, intends to levy a carbon fee on new buildings that connect “to fossil fuel infrastructure.” In New York City, where a recent, top-to-bottom retrofit of the iconic Empire State Building nearly cut its operational carbon emissions in half, officials are considering a gas phaseout for all new construction.

Legislation is pending in Colorado to support building electrification, establish standards for energy performance and limit emissions from gas utilities. Laws to require or encourage gas-free construction are already on the books in Massachusetts and Washington, the state that is considered the vanguard of the movement.

Kjell Anderson, the director of sustainable design at LMN Architects in Seattle, helped craft that city’s new building code. The regulations, which will phase out gas in new commercial buildings, were a direct response to Seattle’s increased greenhouse emissions between 2016 and 2018.

He predicts emissions will drop each year as buildings go all-electric and the local grid adds more renewable energy. The biggest unknown is the balance required between on-site renewables, the grid and energy storage, which he says calls for region-specific approaches.

“Nearly all ‘net-zero’ buildings generate excess energy on many days, while they draw grid power at other times,” Anderson said. “With the rapid expansion of clean-energy development and the significantly reduced cost of renewables, energy flows both ways, so utilities are becoming energy managers instead of just energy generators.”

Like so many of his colleagues and contemporaries, he thinks the transition to a carbon-neutral economy must be expeditious: “The task at hand is scaling the solution — efficiency, electrification and renewable energy — to the scope and urgency of the climate crisis.”

Investa’s race to net zero emissions

Investa’s race to net zero emissions

Introduction
What is a science-based net zero emissions target?
What does Investa’s science-based net zero emissions target look like?
How will Investa achieve net zero emissions?
How is Investa working with tenant customers?

 

Introduction

In the race to net zero emissions, Investa took an early lead as the first Australian property company to commit to a science-based target in 2015. Nina James, General Manager for Corporate Sustainability and Responsible Investment, shares Investa’s progress and explains why Investa customers should care.

When Australia signed on to the Paris Agreement, we agreed to play our part to limit global warming to well below 2°C, preferably to 1.5°C, compared to pre-industrial levels. To achieve this, we must halve greenhouse gas emissions by 2030 and achieve a climate neutral world – or net zero emissions – by 2050.

Around 20% of Australia’s greenhouse gas emissions come from our buildings. Businesses play a central role in driving down greenhouse gas emissions in their commercial offices, but a resilient, zero-emissions future must be underpinned by robust science.

“When Investa committed to a science-based target in 2016, we charted a course to net zero emissions by 2040. To do this, we have set a bona fide carbon reduction target that is verified against the climate change science and the Paris Agreement,” James explains.

 

What is a science-based net zero emissions target?

Any company can set a carbon reduction target. But how do we know that the target is ambitious enough to achieve net zero emissions?

Science-based targets help companies to understand how much and how quickly they need to reduce their greenhouse gas emissions to prevent the worst effects of climate change.

“Investa has always had a strong commitment to third-party verification,” James says. “We have certified our portfolio of assets under the NABERS and Green Star rating systems. We report to GRESB, the global benchmark for sustainable real estate, each year. And we have been a signatory to the UN Principles for Responsible Investment since 2007. When we set our carbon target the same expectation applied.”

Investa established its target through the Science Based Targets initiative (SBTi), a global organisation that sets the ‘gold standard’ for corporate emissions reduction. More than 1,200 companies have committed to cut their carbon footprints and 593, including Investa, have had their targets approved by SBTi.

SBTi’s 2020 progress report shows science-based targets work. The typical company with science-based targets has reduced its direct emissions (Scope 1 and 2) at a rate of 6.4% per year. This exceeds the 4.2% rate needed to limit warming to 1.5°C.

Investa has reduced emissions by a massive 63.3% since 2004.

 

Investa’s science-based target was pivotal for the property industry. By working through the complexity raised by science-based targets, Investa showed everyone that it could be done.

Davina Rooney, CEO, Green Building Council of Australia

 

What does Investa’s science-based net zero emissions target look like?

Davina Rooney, Chief Executive Officer of the Green Building Council of Australia, says Investa’s net zero goal was a “game-changer” for the nation’s buildings.

“Investa’s science-based target was pivotal for the property industry. By working through the complexity raised by science-based targets, Investa showed everyone that it could be done, and gave other property companies the confidence to pursue their own ambitious sustainability goals,” Rooney explains.

Australia’s property industry can achieve net zero emissions by 2050 using technologies that exist today, Rooney adds.

“The Low Carbon, High Performance report finds eliminating emissions from our buildings would also deliver $20 billion in financial savings by 2030, and improve the productivity and quality of life of Australian businesses and households.”

Investa has committed to reduce Scope 1 and 2 greenhouse gas emissions by 60% per square metre of net lettable area by 2030 and 100% by 2040 from a 2015 baseline. We have also committed to reduce Scope 3 greenhouse emissions by 26% per net lettable area by 2030 and 42% by 2040 from a 2015 baseline.

Importantly, this target includes Scope 3 emissions – the emissions that are generated by our tenant customers.

“Reducing our tenant customers’ emissions is embedded in our commitment, and that sets us apart,” James says.

“It says we are accountable for more than what’s in our own backyard. We might not control Scope 3 emissions, but we want to walk alongside our tenant customers, arm in arm, to help them reduce their footprint.”

James says Investa is “thrilled” to see nearly every large Australian property company set competitive targets since 2015. “They’ve used our target as a bookend – and that makes our team proud.”

 

Let’s break down Scope 1, 2 and 3 emissions

Scope 1 emissions – or direct emissions – are from sources that a company owns or controls, like emissions produced during manufacturing, or from business travel in a company car,

Scope 2 emissions are indirect emissions from the purchase of electricity, steam, heating and cooling for the company’s own use.

Scope 3 emissions cover emissions outside a company’s boundary – like the emissions from employees’ commute, purchased good and services, or leased assets, like office buildings.

 

How will Investa achieve net zero emissions?

‘Net zero emissions’ means achieving overall balance between the emissions produced and those extracted from the atmosphere. Buildings can still produce some emissions, provided they are offset by activities that reduce those emissions, like planting forests.

Electricity and gas consumed in Investa’s buildings account for 99.6% of our greenhouse gas emissions. To achieve net zero emissions, we are addressing three areas:

1. Operations. By working alongside tenant customers to uncover new ways to enhance the energy performance of buildings we are making workplaces more productive, healthy and comfortable.

2. Design and construction. Changing the building envelope – considering solar glare and heat, orientation and thermal mass, the design of windows and services, for example – can realise big energy and carbon emissions savings for our customers.

3. Power. Sourcing zero-carbon energy, such as from solar or wind farms, addresses our residual power requirements and helps our customers to meet their net zero targets too.

 

How is Investa working with tenant customers?

Investa’s partnership with customers is at the heart of its strategy to cut carbon emissions.

“We don’t think it’s enough for us to address our base buildings. We want to share our ideas and intellectual property with our customers to drive a shift across Australia,” James explains.

In partnership with the Clean Energy Finance Corporation, Investa has created a free Sustainability Tenant Toolkit to help companies around Australia create low carbon, healthy workplaces.

“We have gathered all the information and ideas from 15 years of operating sustainable commercial offices. We aim to empower our 750 tenant organisations to improve the performance of their own tenancies,” James explains.

The Toolkit attracted nearly 37,000 unique visits in 2020 alone. From analysing the data, Investa knows that people want to understand how buildings influence health, wellbeing and productivity, and how they can actively improve the environmental sustainability of their office space.

Davina Rooney says the Toolkit is a “genuinely impressive piece of work to guide tenants on creating sustainable workplaces”.

“By tackling environmental sustainability from lots of different angles – from design and construction to how people use their office space – Investa has set the industry benchmark.”

James says the feedback Investa receives from tenant customers is “really exciting”.

“Tenants are making great savings in electricity by implementing the tips in our Toolkit. They tell us the Toolkit helps their people understand what wellness in the office looks like, and how engaged employees translate to bottom line benefits,” James says.

“Through the Toolkit, we’ve had direct conversations with 100,000 of our customers. But what makes us really proud is the fact that anyone can access the Toolkit. Sharing our knowledge is how we’ll move Australia towards net zero emissions.

The challenge of climate action is large, but so is Investa’s net zero ambition. This is why a staged approach is important, James explains.

“First, set the target, then gather and analyse the data, then enrol our tenants. That’s what we are doing – walking arm-in-arm with our tenants as an advisor. We are working with our customers to cut their carbon emissions and, at the same time, create more efficient, sustainable workplaces. We’re showing that it can be done.”

 

“We don’t think it’s enough for us to address our base buildings. We want to share our ideas and intellectual property with our customers to drive a shift across Australia.”
