Better green materials are still needed to trigger a revolution in the building sector, experts say

2023-12-14T13:56:00-05:00

Repeated calls for the decarbonization of architecture are sometimes met with criticisms as to their lack of substance, and in some cases, practicality or overall feasibility, Canada's National Observer tells us.

The only mycelium binders on the market are, for example, unsuitable to certain weather conditions, according to Yale Center for Ecosystems and Architecture’s Mae-ling Lokko. Other products like composite wood materials can contain formaldehyde, which puts a damper on the new heights mass timber designs are reaching in Europe and North America. The current limitations of bio-concrete, hemp, and algae materials are also well-known.

To enact a truly revolutionary turn, both additional investments into developing new alternative products and a better understanding of a building’s end-of-life recyclability are needed, Lokko and Naomi Keena of McGill University's School of Architecture told the paper.

Canada and its vast reserves of agricultural waste derived from applicable c...

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 ...

Boston has officially banned fossil fuels in all new city-owned buildings

2023-08-07T15:57:00-04:00

Boston is officially ending its reliance on fossil fuels in government-owned buildings after Mayor Michelle Wu signed a new executive order banning their use in all new municipal construction and renovation projects across the city.

In a press statement released on July 31st, Wu told reporters: “Week after week, we see the signs of extreme heat, storms, and flooding that remind us of a closing window to take climate action. The benefits of embracing fossil fuel-free infrastructure in our City hold no boundary across industries and communities, and Boston will continue using every possible tool to build the green, clean, healthy, and prosperous future our city deserves.”

The initiative is part of a larger Green New Deal for Boston, which takes aim at various issues surrounding topics in the built environment. Boston’s stock of municipal buildings is currently responsible for only 2.3% of emissions city-wide, and proponents say the new mandate will help speed their overall decarboniz...

AIA announces $20 billion in grant funding made available for adaptive reuse and decarbonization projects

2023-08-01T11:22:00-04:00

The American Institute of Architects has announced that nearly $20 billion of the $27 billion allocated by the Greenhouse Gas Reduction Fund (GGRF) under the Inflation Reduction Act has been released by the Environmental Protection Agency.

The EPA has introduced two funding opportunities: the $14 billion National Clean Investment Fund (NCIF) and the $6 billion Clean Communities Investment Accelerator (CCIA), targeted at decarbonization projects and adaptive reuse projects.

Described by AIA as a “pivotal sustainability strategy,” the grant funding is available for nonprofits that meet the recipient criteria noted in Section 134(c)(1) of the Clean Air Act, with an application submission deadline of October 12, 2023.

"It is essential that we prioritize investments in existing buildings that will reduce emissions while also creating jobs, promoting health equity and supporting vulner...

Baking soda may help concrete absorb carbon, MIT researchers find

2023-04-11T11:54:00-04:00

New research from MIT has found that adding sodium bicarbonate, otherwise known as baking soda, to concrete mixtures may make a significant dent in the material’s carbon footprint. The findings, published recently in the journal PNAS Nexus, also suggest that the addition of sodium bicarbonate may accelerate construction times through quicker concrete setting.

The research was led by MIT professors of civil and environmental engineering Admir Masic and Franz-Josef Ulm, MIT postdoc Damian Stefaniuk, doctoral student Marcin Hajduczek, and James Weaver from Harvard University’s Wyss Institute. With concrete production accounting for approximately 8 percent of global carbon dioxide emissions, and concrete being the world’s second most consumed material after water, the team sees innovation in the material’s environmental performance as being a key component to reducing global greenhouse gas emissions.

A heat pump revolution could bring much-needed building decarbonization

2023-02-06T12:09:00-05:00

By 2030, around a quarter of UK buildings should be heated using them, according to the UK government's climate advisory body, rising to 52% by 2050. Electrifying heating will also be key to decarbonising buildings in the US, says Melissa Lott, director of research at the Centre on Global Energy Policy at Columbia University. One study in San Francisco referred to heat pumps as the "single most impactful lever" to reducing emissions.

Communal heatmains can be used to overcome the challenges of digging expensive boreholes for heat pumps in private homes and urban apartment blocks where most of the UK’s population resides. The country’s push to heat half of its homes using heat pumps, which are evolving, puts it squarely in line with Germany and other states looking to leverage the technology in the interest of achieving sustainability goals.

A recently-announced New York City Housing Authority (NYCHA) design contest is also attempting to tackle the affordability issue with window-frame prototypes that cost no more than $3,000 per unit and can be installed in less than two hours.

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.

SOM presents 'ready-to-build' Urban Sequoia NOW design at COP27

2022-11-08T17:53:00-05:00

Skidmore, Owings & Merrill (SOM) has revealed an update to its Urban Sequoia project it says can be built right now, during a presentation that took place today at the COP27 climate summit in Sharm El-Sheikh, Egypt.

SOM Partner Chris Cooper was on hand to make the presentation of his firm’s refined design for a carbon-sequestering building that can be used as a weapon in the fight against carbon emissions globally, three-quarters of which are generated from urban areas alone.

“We recognize the need to alter the trajectory of climate change by going beyond net zero,” Cooper said during the presentation. “We need to take carbon out of the atmosphere through the built environment, and we have developed a design to do just that.”

Despite some considerably less-marketable obstacles to its effective implementation, the technology for carbon sequestering has come a long way in its development to offer itself as a plausible answer to the challenge posed by the need to a...

Researchers have found ways to use mushrooms to decarbonize construction waste

2022-10-21T14:59:00-04:00

Megadeveloper Lendlease is one of the entities behind a new study into the use of mushrooms as a means of decarbonizing construction waste through their application on discarded asphalt roofing shingles.

The company teamed with Rubicon Technologies, Mycocycle, and Rockwood Sustainable Solutions to complete a pilot project at the latter’s facility in Lebanon, Tennessee.

Shingles removed from a total of 214 homes following a recent re-roofing project at the U.S. Army’s Fort Campbell installation in nearby Kentucky were then broken down thanks to an infused mix of three different strains of fungi in a process called mycoremediation.

"Every asphalt shingle from those 214 homes would have gone to a landfill," Sara Neff, Head of Sustainability at Lendlease Americas, said of the 11 to 13 million tons of the product the EPA estimates winds up in landfills annually.

"There was simply no viable use for them," she continued. "We understand the i...

New York selects six Empire Building Challenge partners to boost the state's energy efficiency

2022-10-10T09:00:00-04:00

New York Governor Kathy Hochul has just announced the addition of six new strategic partners to the $50 million Empire Building Challenge in aims of enhancing the state’s stock of energy-efficient buildings.

The newly-added partners will be tasked with developing "highly repeatable" solutions to reducing carbon emissions in the heating and hot water systems of roughly 5.6 million square feet of high-rise buildings statewide that are included in the Challenge.

Brookfield Properties and Tishman Speyer lead the groups included in the program’s expansion, which now covers some 125 million square feet of commercial and multifamily properties and over 1,500 units of housing. The new interests selected by the New York State Energy Research and Development Authority (NYSERDA) include:

Amalgamated Housing Corporation, who will team with EN-POWER GROUP and Egg Geo on Tower I & Tower II, 3965 - 3975 Sedgwick Avenue in the Bronx.
Boston Properties, who pairs with Jaros, Baum, & Bolles Consulting...

Boston may soon become the next major American city to ban fossil fuels in new buildings

2022-08-19T17:46:00-04:00

Boston Mayor Michelle Wu has announced an ambitious new city-wide plan that would eliminate the use of fossil fuels in new developments and major renovations in an effort to take "every possible step to climate action."

If passed, the Home Rule Petition to the state’s new Bill H.5060 would make Boston the next large city to adopt such measures, following New York, Los Angeles, San Jose, Seattle, and Berkeley which have all codified similar mandates into local construction laws in recent years.

Furthermore, the city has announced the formation of a special advisory committee made up of local architects, environmental and public health experts, real estate developers, and other stakeholders who will all be tasked with creating guidelines that will later be recommended by Wu as ordinance to the City Council.

In a press statement, Councilor Kendra Lara said: "Implementing meaningful e...

U.S. Department of Energy grants $39 million to projects developing carbon-storing buildings

2022-07-21T19:01:00-04:00

The U.S. Department of Energy (DOE) has awarded $39 million to 18 projects dedicated to developing technologies that can transform buildings into net carbon storage structures.

The initiative titled the Harnessing Emissions into Structures Taking Inputs from the Atmosphere (HESTIA) program is being led by the Department of Energy’s (DOE) Advanced Research Projects Agency-Energy (ARPA-E).

The awardees will use the funding to develop alternative building materials and construction techniques. The decarbonization goals for the program align with President Biden’s plan to reach zero emissions by 2050, aiming to increase the total amount of carbon stored in buildings to create carbon sinks.

“This is a unique opportunity for researchers to advance clean energy materials to tackle one of the hardest to decarbonize sectors that is responsible for roughly 10% of total annual emissions in the United States,” U.S. Secretary of Energy Jennifer M. Granholm remarked on the initiative.

Los Angeles the latest city to adopt digital twin technology to cut carbon emissions

2022-06-09T21:11:00-04:00

Cityzenith, a Chicago-based digital twin platform, announced last week that it is partnering with the Los Angeles branch of the U.S. Department of Energy’s Better Buildings Challenge to help construct a digital twin, or virtual replica, of a section of the city to help make its buildings more sustainable and reduce carbon emissions.

The project will initially center on the downtown Los Angeles neighborhood of Bunker Hill. Cityzenith’s SmartWorld digital twin product will be implemented to enable building owners to simulate their financial paths to net-zero emissions. This is part of Cityzenith’s "Clean Cities — Clean Future" initiative, which provides cities with a free digital twin in order to virtually test potential decarbonization efforts before implementing costly plans in the real world.

Previously on Archinect: Digital twin of downtown Las Vegas unveiled in effort to cut emissions

As noted by Melissa Goldin of Construction Dive, the Bunker Hill project will focus on data related to decarbonization efforts for a major public building and the surrounding area. Energy or building management systems, occupancy readings, and architectural information are among the variables that will be examined. The digital twin will have the potential to expand to cover the rest of the city and address other city planning i...

LA is banning the gas burner in favor of electric appliances

2022-06-01T11:47:00-04:00

Citing the climate crisis, the Los Angeles City Council voted Friday to ban most gas appliances in new construction, a policy that’s expected to result in new homes and businesses coming equipped with electric stoves, clothes dryers, water heaters and furnaces. The nation’s second-largest city was late to the game, said Councilmember Nithya Raman, the policy’s lead author — but no longer.

Raman’s motion echoes that of many other cities in the state as well as a recent proposal to phase out non-electric car sales by the year 2035. It also includes a provision that all newly-constructed buildings be emissions-free, a requirement it first adopted for all municipal properties in 2020.

Current estimates have it that 10% of all emissions can be traced to natural gas installations in California, with another 15% being attributed to the electric grid needed for those homes and businesses.

New CTBUH study on tall mass timber gives us a look at the impacts of the material industry-wide

2022-05-26T13:37:00-04:00

A new study from the Council on Tall Buildings and Urban Habitat (CTBUH) has revealed important statistics that provide a clearer picture of the present state of tall mass timber construction across the globe.

There are now a total of 66 completed mass timber projects worldwide totaling of least 8 stories or higher. Nearly two-thirds (64% or 54 buildings) of all projects are residential, while office buildings account for 19% (16 buildings), and the mixed-use typology currently makes up 14% (12 buildings). Including projects that are currently under construction or proposed, there were 139 total projects matching the audit’s criteria.

In terms of height, 12 of the 20 tallest structures are located in Europe. Scandinavia had 4 of those, while the UK and Australia had 3 and 5 apiece, respectively. Additionally, the height of the world’s tallest timber building, now officially the soon-to-be-completed 25-story Ascent tower in Milwaukee, has tripled in jus...

Is carbon offsetting a misleading tool of the building industry?

2022-05-16T15:16:00-04:00

Six months after the COP26 climate summit in Glasgow, columnist Kunle Barker wrote in the UK Architects' Journal to take a stand against the industry’s oneiric focus on “lofty ideals of zero-carbon and on soundbites” and towards a more considered system of new project evaluation, advocating for the “need to develop a viability methodology that is independent, objective and focused on carbon impact versus social need.”

“Let’s rid ourselves of these conceited phrases and instead focus on the real issues,” he wrote, arguing that need will always push architects into costly demolition efforts and away from restoring structures that may, in many cases, be better suited for adaptive reuse. “Offsetting is not sustainable. In fact, it's not even close to being sustainable, and most worrying of all, it is allowing lazy, ego-driven designs to be accepted by us all. We must find an objective and fair way to assess if (and how) a building should be constructed. This is the only way the built en...

Arup completes the Netherlands' tallest timber-hybrid residential building

2022-03-31T19:16:00-04:00

Arup has designed and engineered the Netherlands’ tallest timber-hybrid residential building.

Completed this year, HAUT is part of the country’s commitment to becoming climate-neutral by 2050, in which the use of timber as a building material has been identified as one of the most effective ways to accelerate decarbonization. As noted by Arup, in 2021, over 80 Dutch companies signed the Green Deal covenant Houtbouw of the Metropoolregio Amsterdam. With this, the nation's capital and most populous city is committing to the goal of building at least one in five buildings using primarily timber from 2025 onwards.

Previously on Archinect: Arup, TEAM V to build world's tallest timber residential building in Amsterdam

HAUT was conceived in 2016 with the aim of being of both sustainable and high architectural quality. Situated near the Amstel river, the structure is one of the tallest timber-hybrid buildings in the world, standing 21 floors tall at nearly 240 feet. It was also certified B...

NYCHA is challenging designers to create an affordable heat pump for 24,000 apartment units

2022-01-27T17:23:00-05:00

A creative answer to one of the most pervasive issues in American public housing is being sought by one of the largest civic authorities in the country as the New York City Housing Authority (NYCHA) has issued a challenge to design an affordable new all-electric heat pump for the 21st century.

NYCHA has made design challenges a part of its program before. As Grist noted, the agency has previously issued similar challenges to older generations of industrial manufacturers, including a late-90s contest to design more energy-efficient refrigerators for its properties, which at the time, did not offer ample enough space for the appliances. A design from Maytag won the contest and was widely adopted by a number of other regional housing authorities in order to reduce energy costs.

Now, with the tragedy of this month’s devastating Bronx apartment fire in its recent purview, NYCHA is once again asking for help from the design community in solving a silent problem that has drawn increasing ...

The U.S. Department of Energy has invested over a billion dollars into mostly failed carbon capture programs since 2009

2021-12-31T11:08:00-05:00

The Biden administration wants to shove more money into projects that are supposed to capture CO2 emissions from power plants and industrial facilities before they can escape and heat up the planet. But carbon capture technologies that the Department of Energy has already supported in the name of tackling climate change have mostly fallen flat, according to a recent report by the watchdog Government Accountability Office.

According to the report, the Department of Energy (DOE) has invested about $1.1 billion in 11 carbon capture and storage (CCS) demonstration projects since 2009. Of those, only three were ever built, however, the sole participating coal plant shut down in 2020, leaving only two industrial projects in operation.

The U.S. Government Accountability Office (GAO) suggests that Congress consider implementing a mechanism for greater oversight and accountability of DOE CCS demonstration project funding. GAO also recommends that the DOE improve its project selection and negotiation processes and that they should establish more consistent scopes, schedules, and budgets for projects.

Biden administration issues mandate to make federal vehicles and buildings run on renewable energy by 2050

2021-12-14T13:46:00-05:00

President Biden on Wednesday set in motion a plan to make the federal government carbon neutral, ordering federal agencies to buy electric vehicles, to power facilities with wind, solar and nuclear energy, and to use sustainable building materials.

Biden called for the transformation of 300,000 government buildings, 600,000 cars and trucks, and the use of its annual $650 billion budget for goods and services to meet his goal for a carbon-neutral federal government by 2050.

Detailed by The New York Times, his timetable for the transition is as follows: By 2030, Biden wants the federal government to purchase electricity only from sources that do not emit carbon dioxide. By 2032, the administration wants the emissions from building operations, such as heating, halved. And by 2035, all new federal car and truck purchases would also be zero-emissions.

There’s uncertainty over whether Biden’s climate goals will come into fruition as Congress has yet to approve a $1.7 trillion spending bill that would help achieve his targets and the expected limitations posed by the Supreme Court.

Here is what happened in Glasgow after the underwhelming conclusion of COP26

2021-11-15T14:38:00-05:00

The ending of this year’s COP26 conference has left many architects to ponder how effective the mostly non-representative group of negotiators were in addressing the skepticism and high expectations coming into the meeting that is meant to address what is undoubtedly the greatest moral issue of our time.

The conference concluded on Saturday with a resounding sense of discord, despite a historic pact signed by 197 countries to close the conference. Here’s a look at some of the highlights and tangible changes that came out of the two-week meeting in Glasgow.

Coal

Coal was the biggest hangup at the conference by far, with the final language of the deal constituting what British Prime Minister Boris Johnson declared a “death knell” for the industry. Although more than 40 countries agreed to end their own domestic production of coal, India, with help from China and Iran, singularly stalled the pact until an 11th-hour deal changed the text from “phase out” to the more ambiguous “phase dow...

SOM unveils vision for carbon-absorbing cities at COP26

2021-11-12T14:28:00-05:00

With COP26 entering its final day in Glasgow, Skidmore, Owings & Merrill have used the event to unveil their vision to transform the built environment into a network for absorbing carbon. Titled 'Urban Sequoia,' the project is centered on the concept of “forests” of buildings which sequester carbon and produce biomaterials to support a new carbon economy.

To create the scheme, SOM based their approach on an optimization of building design, a minimizing of materials, the integration of biomaterials, and the use of advanced biomass and carbon capture technologies. As a result, the firm estimates that if every city around the world built an Urban Sequoia in line with their design, the built environment could remove up to 1.6 billion tons of carbon from the atmosphere every year.

“We are quickly evolving beyond the idea of being carbon neutral,” said SOM Partner Chris Cooper as the project was unveiled. “The time has passed to talk abou...

Ithaca becomes the first US city to start 100% decarbonization of its buildings

2021-11-08T17:24:00-05:00

Far from Glasgow and COP26, Ithaca, New York, just made an unprecedented move to tackle climate change and the city’s carbon footprint. In a unanimous vote on Wednesday night, Ithaca’s city council approved the full decarbonization of its buildings.

This is the first US city to begin work on a 100% decarbonization plan. It secured $100 million in private financing from private equity partner Alturus to support the effort, a move that may be more effective in tackling emissions than federal and state efforts. Ithaca’s energy efficiency partner BlocPower brought the investors on board to pay the upfront costs of the project.

According to Ithaca’s sustainability director, Luis Aguirre-Torres, the strategy to fund these climate projects is to not rely on government money but to secure private investment and combine it with incentives from the government. This can reduce the cost of capital and interest rates for project finance. Torres said that Ithaca’s goal is to set the ratio at 1 to 20 for taxpayer versus private investment funding.

Ithaca’s plan will cover electrification projects for 1,000 residential buildings and 600 commercial buildings in the first phase of a total 6,000 building inventory. Buildings are the first target...

U.S. Department of Energy says solar energy has the potential to produce 40% of the nation's electricity by 2035

2021-09-08T13:13:00-04:00

A new study released by the U.S. Department of Energy (DOE) highlights the role solar energy could play in decarbonizing the country’s power grid.

The Solar Futures Study shows that by 2035, solar energy has the potential to power 40% of the nation’s electricity and employ as much as 1.5 million people, without raising electricity prices. This comes following the installation of a record amount of solar in 2020, which currently accounts for 3% of the country’s electricity supply.

The study shows that by 2035, the U.S. would need to quadruple its yearly solar capacity and provide 1,000 GW of power to ensure a renewable-dominant grid. The report goes further to say that by 2050, solar energy could provide 1,600 GW for a zero-carbon grid.

California to mandate solar panels for new buildings

2021-08-12T13:26:00-04:00

California is set to mandate the inclusion of solar panels and battery storage for new buildings. Following a unanimous vote of approval by the California Energy Commission, the measure is expected to be included in an overall revision of the state’s building code in December of this year, before coming into effect on January 1st, 2023. The move, made as part of the new 2022 California Energy Code, will make California the first state in the U.S. to mandate solar panels and battery storage for new commercial and high-rise residential buildings.

The new measures will apply to a wide range of buildings, including hotels, offices, retail, restaurants, schools, grocery stores, and civic spaces such as theaters, auditoriums, and convention centers. The measures would also require new homes in California to be wired in an accessible way, to enable the future transition of heating and appliances away from natural gas and towards electric sources. Other measures include the encouragement of...

Achieving a future of zero-emission construction

2021-06-30T19:31:00-04:00

Decarbonising the construction industry is something in which Oslo wants to lead the world. And it's with good reason. At present, the construction sector alone is responsible for more than 10% of global greenhouse gas emissions. The impact of construction is even more evident when looking at CO2 emissions from energy use – with the sector contributing 38% of the world's emissions.

Matthew Keegan explores how cities like Oslo, Helsinki and Copenhagen are working to clean up one of the world's most high-emission industries.
