The tool allows architects working in Forma to subject their early design concept to an AI-powered analysis that can evaluate design concepts and iterate toward reducing carbon emissions.

Located in the ‘analysis’ tab in the Forma web application, the analysis allows users to define site-wide analytical properties as well as those specific to individual buildings. Parameters that can be specified include building function, structural system, and envelope factors such as cladding and window-to-wall ratio.

British AEC groups urge government action on embodied carbon regulations

2024-01-31T19:21:00-05:00

A group of 11 AEC industry groups in the United Kingdom, including the Royal Institute of British Architects (RIBA), Chartered Institute of Building, and UK Green Building Council, have joined together in urging the government toward taking action on restricting embodied carbon emissions in the built environment ahead of an important national election that’s expected for November.

Their call endorses an amalgam of existing policy pushes while espousing lawmakers to include at least a portion of its findings into their respective manifestos with benchmarks for specific mandates and enforcements set for the end of this year, 2026, and 2028, respectively.

RIBA President Muyiwa Oki said: “Our message is clear — embodied carbon regulation is critical to reaching net zero. As built environment professionals, we understand our duty to reduce emissions and have been leading the charge. We now need urgent action from the next government to deliver a greener future that we deserve.”

New York to introduce ‘first-in-the-nation’ mandate for concrete emissions

2023-09-26T12:21:00-04:00

New York State has announced the adoption of a ‘Buy Clean Concrete’ mandate for state agencies, described by Governor Hochul’s office as a “first-in-the-nation” commitment to environmental sustainability. The plan contains mandatory rules for establishing emissions limits on concrete used in state-funded public building and transportation projects.

Starting from January 1, 2025, Environmental Product Declarations (EPDs) must be submitted for all concrete mixes used in qualifying state construction projects and must demonstrate that they achieve an environmental impact below the limits set by the state. The state hopes such EPDs will “provide transparency and a more robust accounting of a concrete mix’s greenhouse gas emissions and enable state agencies and other stakeholders to make more informed choices in reducing emissions.”

The measure will apply to state agency contracts exceeding $1 million that involve the use of more than 50 cubic yards of concrete. Exceptions are provided f...

Further action on decarbonization in the construction sector is needed, urges UN/Yale study

2023-09-15T17:21:00-04:00

A new report driven by the UN Environment Programme (UNEP) and Yale University's newly-formed Yale Center for Ecosystems + Architecture (Yale CEA) has recommended drastic reductions in the industry’s use of certain construction materials as it faces the environmental headwinds of sector-wide change.

While heeding a "back-to-the-future revolution" in methods and products/technologies used for building, the authors say the worldwide growth of urbanization has necessitated an overabundance of new buildings constructed using an unacceptable amount of concrete and other harmful materials. The findings of the report suggest the efficacy of reusing existing buildings at a larger scale while at the same time concentrating more resources toward the production of adequate alternatives in addition to adopting a "circular economy" and policies that help to curb the industry's 37% share of global emissions.

Where the report recommends a three-pronged solution toward reducing embodied concrete e...

20% of landscape architects expect to see greenhouse gas emissions budgets in future projects, ASLA survey finds

2023-08-22T17:08:00-04:00

The American Institute of Landscape Architects has published the results of a members' survey on the role of landscape architecture products in aiding decarbonization and biodiversity in the built environment. Insights were garnered from 454 landscape architects, designers, and educators out of the ASLA’s member base of approximately 15,000.

A significant 55% of respondents stated that their clients do not establish a greenhouse gas emissions budget for their projects. However, 20% foresee it as a potential future requirement. When asked about the data that would assist in accounting for emissions, 51% prioritized embodied carbon factors for materials, closely followed by 50% wanting projected carbon sequestration details for tree species specification.

Regarding accessing Environmental Product Declarations (EPDs) and emissions assessments, 55% advocated for a curated register of baseline data, possibly developed by ASLA or a similar body. When procuring from manufacturers, 34% of p...

California becomes first U.S. state to mandate embodied carbon reduction measures

2023-08-08T16:27:00-04:00

California has become the first U.S. state to establish general code standards mandating the reduction of embodied carbon emissions in large commercial and school buildings. The decision, recently announced by the California Building Standards Commission, encompasses commercial buildings exceeding 100,000 square feet and school projects over 50,000 square feet. The regulations will take effect on July 1, 2024.

Embodied carbon represents the greenhouse gas emissions associated with building materials throughout their life cycle. This includes not only the manufacturing and transportation of these materials but also their installation, maintenance, and eventual disposal.

The recent updates were integrated into the 2022 California Green Building Standards Code. They provide three distinct compliance avenues for design experts: Reusing at least 45% of an existing structure; Using materials that adhere to specified emission limits; A performance-based approach employing a Whole Building ...

SOM introduces Whole Life Carbon Accounting service for developers and design professionals

2023-07-12T12:20:00-04:00

A new Whole Life Carbon Accounting service from Skidmore, Owings & Merrill (SOM) was unveiled last month in an effort to help building owners and developers make accurate decisions about building performance at all stages of the design phase while pushing the industry further toward a much-needed reduced carbon future.

The service was created by the firm’s sustainability team and targets the important early-stage embodied carbon emissions of a building, offering a consolidation of disparate carbon assessments that can lead to drastic miscalculations of emissions on projects in between their initial design and completed construction.

“[The] gaps between traditional assessments and a building’s true performance can lead to a performance gap of up to five times more energy use and/or carbon emissions between predicted and actual values. Our service puts an end to this,” SOM’s Sustainability Director, Mina Hasman, explained via a press announcement.

Port Authority of NY & NJ reaches milestone with new low-carbon concrete standards

2023-06-29T14:09:00-04:00

The Port Authority of New York and New Jersey announced earlier this month that it has reached a major milestone in one of the most ambitious low-carbon concrete programs of its kind among U.S. transportation agencies.

Originally introduced in September 2020, the Clean Construction Program aims to reduce embodied carbon, promote the circular economy, and reduce air pollution from construction across all of the Authority’s projects through a range of initiatives. They include the incorporation of LEED and Envision-equivalent standards, utilizing low-carbon concrete, collecting environmental data from contractors, facilitating pilot projects, waste matching for concrete, asphalt, and soil, and requiring low-emissions vehicles on site.

The agency took a major step forward by significantly strengthening its requirements to use sustainable concrete mixes in all future construction projects as part of its commitment to achieving net-zero emissions by 2050.

Team of UBC students builds one of Canada's first near-zero embodied carbon campus spaces

2023-04-21T12:33:00-04:00

A team of students from the University of British Columbia (UBC) has built a near-zero embodied carbon building on campus using hempcrete, wood, and steel as primary materials.

Called the Third Space Commons, the project was led by Third Quadrant Design, UBC’s first green building design team. The group is comprised of 60 students from the Faculty of Applied Science and the Sauder School of Business. The building is a wooden structure spanning 2,400 square feet, made from the adaptive reuse of an existing single-family home on the campus. Every aspect of the project, from the materials to the building methods, were chosen to decrease and capture carbon emissions.

The building’s thermal insulation is made of hempcrete, a concrete substitute made of lime and hemp fibers that is effective in carbon sequestration. Its foundation was constructed with reusable steel piles, and, for most of the project, the team used light wood framing instead of engineered wood, which contains fossil fuel-derived adhesives. The team also reused many materials from other construction sites in Vancouver, including the building’s windows, solar panels, appliances, and lumber, whic...

Swiss researchers have developed a carbon-storing building insulation made from plant-based materials

2023-02-13T15:49:00-05:00

A Swiss research team from Empa's Building Energy Materials and Components Lab explores the potential for using raw, plant-based materials as insulation for buildings.

Led by scientist Dr. Jannis Wernery and researchers from the Zurich University of Applied Sciences, the project is based on binding carbon dioxide in insulation materials, preferably waste products from agriculture and forestry, over the long term. This method aims to combat embodied greenhouse gas emissions in buildings by removing carbon from the atmosphere. Carbon stored in biomass can be permanently fixed through the use of heat treatment.

The resulting material, known as biochar, can store carbon dioxide throughout the life of a building and be used again following the deconstruction of a building, reports Rémy Nideröst of Empa. However, Dr. Wernery explains, "there is still a lot to do before the idea can be put into practice."

The researchers must ensure that the new insulation materials can be used as a fe...

2023 could see a rise in green building policies centered on embodied carbon

2023-01-30T20:27:00-05:00

For much of its recent history in mitigating climate change, Denver has concentrated on buildings’ operational energy — the energy needed to run basics like heating, air conditioning, lighting and hot water. That will shift in May, when Denver’s newly adopted green code takes effect, said Christy Collins, green communities specialist with the local government.

Denver’s new green code will make it so a building’s embodied carbon is considered. It will provide minimum requirements for the siting, design, construction, and plans for the operation of projects. Commercial projects in Denver are now required by law to choose around 10% of the green code to follow. According to Smart Cities Dive, similar policies that address embodied carbon alongside the electrification of buildings and other decarbonization efforts are set to grow this year.

Additionally, there has also been a rise in policies designed to foster a circular economy, such as salvaging materials and deconstructing buildings rather than demolishing them. This expansion of green policies can be attributed to the recently passed Inflation Reduction Act, which includes $1 billion in grants to help states deliver new residential and commercial building codes.

Penn State to study how fungal biomaterials can help reduce construction waste

2022-12-19T16:24:00-05:00

Researchers at Penn State are undertaking a study into whether fungal materials can replace traditional acoustic insulation funded by the 2022 AIA Upjohn Research Initiative. The team behind the effort, funded in 2021 by both an AIA Upjohn Research Initiative grant and a SOM Foundation Research Prize, is being led by assistant architecture professor Benay Gürsoy from Penn State’s College of Arts and Architecture Stuckeman School - Department of Architecture.

The project is titled Fungal Biomaterials for Sustainable Architectural Acoustics and builds on Gürsoy and her team's work at Penn State’s Form and Matter (ForMat) Lab, whose specialty involves fabricating biodegradable building components using mycelium. The new research path will focus specifically on the acoustic absorption properties of mycelium, with the goal of designing and building acoustic panel prototypes to be tested in the built environment.

3XN completes 'world’s largest upcycled tower' in Sydney

2022-11-18T11:07:00-05:00

Copenhagen-based studio 3XN has completed Quay Quarter Tower in Sydney, Australia, described by the firm as the “world’s most comprehensive upcycling of an existing tower.” The scheme, which sees the retention and transformation of an existing 1970s tower near the city’s waterfront, was recently awarded the 2022 International High Rise Award for what the jury determined to be an “extraordinary combination of upcycling and densification.”

Situated on 50 Bridge Street, the project centers on the former AMP Centre, which, when constructed in 1976, was the tallest building in Sydney at 617 feet in height. The building’s transformation into the Quay Quarter Tower saw 3XN retain 65% of the original building’s structure, including beams, columns, and slabs, and 95% of its original core. In addition, new floorplates were added to the existing plates in order to double the usable area and increase the building’s capacity from 4,500 daily occupants to more than 10,000.

Food for thought on circular design and who should own the built environment

2022-10-11T12:43:00-04:00

Back in June, we covered news of research set to be undertaken at Penn State on the subject of embodied carbon in cities. The research, one of many stories this year focusing on embodied carbon, signals a growing awareness in academic and professional circles of the need to include whole-life perspectives on buildings when calculating their environmental impact: from conception and construction to demolition and reuse.

Given the sizeable 40% impact of the AEC sector on global carbon emissions, it is no surprise that conversations on embodied carbon, life-cycle analyses, and our attitude towards waste in buildings have also garnered mainstream attention.

New study finds that modular construction produces 45% less carbon than traditional methods

2022-06-15T15:03:00-04:00

Factory-produced homes can produce up to 45% less carbon than traditional methods of residential construction, according to new research by academics from the University of Cambridge and Edinburgh Napier University. A study found that two modular housing schemes designed by HTA Design, consisting of a total of nearly 900 homes, saved a combined 28,000 tonnes of carbon.

The two schemes studied were the 44 and 38-story Ten Degrees towers in London’s Croydon borough, the world’s tallest completed modular building, and The Valentine, a 10-story student housing project in London’s Redbridge. Both were completed in 2020. The report found that these developments achieved embodied carbon savings of 41% and 45%, respectively, compared to traditional construction methods.

This difference comes down to modular buildings requiring less carbon-intensive products, such as concrete and steel, and less transport for on-site workers and materials. According to University of Cambridge senior research associate Tim Forman, the study highlights the importance of quantifying carbon in construction and across a building’s life cycle. The results make a strong case for the broader adoption of modular construction, especially as it has the potential to address the challenges of the climate crisis and the shortage of housing.

It will also cover the procurement of renewable energy and the treatment of residual emissions, including carbon offsetting. The ...

Studio Gang begins construction on Populus, the 'first carbon-positive hotel in the U.S.'

2022-04-25T12:10:00-04:00

Construction has begun on the Populus Hotel in Denver, Colorado. Designed by Studio Gang, the 13-story, 265-room hotel is described by the team as “the first carbon-positive hotel in the United States,” and the first Studio Gang project to be built in Colorado.

According to the architects, the scheme’s distinctive façade was informed by the patterns found in Colorado’s native Aspen tree, the Populus Tremuloides. The façade is defined by “lids” extending out over each window, which offer passive shading and channel rainwater away from the windows.

The hotel design was first revealed on Archinect in February 2021 and received mostly skeptical responses from our readers.
