Henning Larsen debuts Open Detail, a digital biomaterials resource for architects

2024-03-21T18:34:00-04:00

Henning Larsen has unveiled a new tool for designers that allows them access to a database of biogenic materials examples taken from around the world.

The firm debuted its new Open Detail resource at the AEC Hackathon in Copenhagen. Together with collaborators Copenhagen School of Design and Technology (KEA), Ramboll, Speckle, and Chevrant, the entry took home first place for the 'Best Mashup Project' at the Hackathon.

Now, their aim is to "foster a shift towards low-carbon architecture" by making such "tangible" biogenic design solutions more easily accessible to the public and practitioners as an open-source repository and knowledge-sharing platform.

The searchable Open Detail will allow users to contribute and download material details in either 2D or 3D format once actualized. Henning Larsen says this is "only the beginning" for Open Detail, adding that the project's off...

Biden-Harris administration defines future of zero emissions buildings

2024-02-09T11:41:00-05:00

In a landmark initiative, the Biden-Harris Administration has released the draft National Definition for a Zero Emissions Building, setting a transformative standard for the construction sector. This comprehensive definition targets all new buildings not owned by the federal government, stipulating that they must achieve high energy efficiency (in the 75th percentile or above), eliminate on-site emissions, and be powered by clean energy sources.

This move is part of a broader effort to mitigate climate change impacts by ensuring that the future of construction aligns with environmental sustainability goals. The definition is poised to serve as a critical framework for both new constructions and existing buildings, aiming for a measurable reduction in operating emissions across the board.

The Pentagon will install solar panel array as part of $55 million DOD initiative

2024-02-03T08:00:00-05:00

The Pentagon has announced it will be installing a solar panel array on its roof in a historic first that’s part of a new $55 million Department of Defense clean energy initiative at military installations in the United States and Germany.

The DOD has been active in attempting to mitigate the large carbon footprint caused by the U.S. military with similar conservation strategies for several years. The money for the new solar panels is being sourced from a larger Department of Energy program that will spend $104 million in total on 31 projects affecting ten other federal agencies. The DOD says this is necessary to bolster its energy resilience and defense operational capabilities while also improving the quality of life for service members living and working at bases full-time.

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.”

AEC firms sign on to Biden Administration’s definition of zero-emissions buildings

2024-01-19T12:53:00-05:00

An effort by the Biden Administration to establish a new national definition of zero-emissions buildings is gaining traction after leaders representing a group of 69 different AEC firms working in the U.S. added their support in a letter that was circulated earlier this week.

Prominent architecture firms, including SOM, NBBJ, Payette, Lake|Flato, Curtis + Ginsberg, DIALOG, FXCollaborative, Handel, and EskewDumezRipple, were among the architecture firms whose principals signed on to the pledge. The signature drive was initiated by Maine-based studio OPAL in coordination with the Building Green Sustainability Leader Peer Networks.

Under the proposed new standards, a “net zero emissions building” would obtain “high” (e.g., the 75th percentile) energy efficiency ratings, be free of any on-site emissions, and be powered purely by clean energy sources. Existing buildings will require an ENERGY STAR score of 75 or higher or a measured whole building energy use intensity (or EUI) of at lea...

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.

COP28 deal agreed amid controversy over ‘phasing out’ of fossil fuels

2023-12-14T11:44:00-05:00

A climate deal has been struck by global leaders at the COP28 UN climate summit in Dubai following days of negotiations. The agreement calls for all countries to move away from using fossil fuels, though stops short of phasing them out. The final text, signed by 200 countries, recognizes a “need for deep, rapid, and sustained reductions in greenhouse gas emissions.”

The pact calls on countries to “transition away” from fossil fuels for energy systems but not for other sectors such as plastics, transport, or agriculture. At the beginning of the conference, the hosting UAE president had proposed a deal to “phase out” fossil fuels entirely; language explicitly called for by a coalition of over 100 countries. However, an initial draft of the deal removed the reference to “phasing out” fossil fuels, as did the final agreement, leading one delegate representing small island states to claim the final text contained a “litany of loopholes.”

Among the commitments in the deal are a tripling o...

EU member states agree to major building emissions cuts at COP28

2023-12-12T18:21:00-05:00

If approved in its current form, the deal struck on Thursday night will also force member states to put solar panels on more buildings, starting with new public buildings and offices and expanding to include new homes by 2030. [...] It is a compromise on the European Commission’s original proposals to renovate the leakiest homes, which member states had fought fiercely.

The EU’s pledge mandates that all new buildings will have zero emissions from fossil fuels in that timeframe, with heating systems derived from fossil fuels phased out by 2040. The expansion of heat pump subsidies will be a decisive factor, along with the mandatory installation of solar panels on everything except heritage architecture, churches, and agricultural buildings by the decade’s end. Also at the conference, six other member states joined the U.S., Canada, and UK in pledging their commitments to the UNEP Buildings Breakthrough challenge that will further reduce emissions by 2030. Signatories will also have until 2035 to cut emissions in residential structures by at least 20%.

Still, the Climate Action Network’s Eva Brardinelli, told the Guardian: “The final agreement on the directive missed a significant opportunity to lift millions out of energy poverty and cut our dependence on fossil fuels.”

The changes are likely to be formally adopted via the European Parliament in th...

Washington State effectively bans fossil-fueled appliances in new construction

2023-11-30T13:39:00-05:00

It will soon become nearly impossible to install fossil-fueled appliances to heat new homes and businesses in Washington. [...] The codes will require new homes and buildings to meet the same total energy performance as those built with electric heat pumps while allowing builders flexibility to choose appliances. Basically, if builders choose gas appliances, they will need to make up the efficiency losses elsewhere in the construction.

The state’s building code update puts them in league with California, Maryland, and major cities New York, Los Angeles, and Boston to have adopted similar policies.

The new amendments offer a “watered-down” alternative to a proposed electric heat pump mandate that was abandoned in the wake of a federal ruling against Berkeley, California’s natural gas ban from 2019.

The state’s building and construction industry is one of many being targeted by lawmakers in an effort to eliminate all greenhouse gas emissions by 2050.

British building firms urge a halt to 'regressive' Tory environmental policy delays

2023-10-10T17:24:00-04:00

Several leading design and construction firms in the UK have signed onto a new appeal urging Conservative Prime Minister Rishi Sunak to halt his program of delayed implementations of key environmental building regulations in the interest of protecting a net-zero carbon emissions future in the country.

The Guardian first shared news of the letter, which called these delays “simply reckless,” just days after issuing a damming analysis of the benefits reaped by some builders as the ambitions of the climate movement have been vastly forestalled.

“We are disappointed at your narrative that delaying climate action would reduce costs to households. The longer we delay and the more we see stop-start piecemeal policy making, the harder and more expensive the task becomes,” a portion of the text reads.

SOM, Perkins&Will, and WilkinsonEyre were amongst the 114 signatories, joining AECOM, Buro Happold, and Arup on a docket that was formally organized by the UK Green Building Council. Along with...

Boston’s new Winthrop Center is now officially the largest Passive House office building in the world

2023-10-06T17:58:00-04:00

The new Winthrop Center in Boston by Handel Architects has just been certified by the Passive House Institute (PHI) as the largest Passive House office design in the world, according to an announcement made Friday by its developer Millennium Partners.

Inaugurated in the spring after a six-year concept and construction phase, the 691-foot mixed-use tower includes 812,000 square feet of Class A office space and another 510,000-square-foot segment with 317 luxury residences within its 52-story design.

The office component of the Center, which earned the PHI designation, incorporates between 30 and 35% more fresh air than a typical commercial design. Millennium Partners shares: "A typical Class A building in Boston’s existing stock uses 150% more energy and existing LEED Platinum buildings in Boston use 60% more energy than Winthrop Center’s office space."

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...

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...

3XN GXN and British Land share new transformation project of London's Euston Tower

2023-07-13T13:57:00-04:00

3XN GXN, alongside property development company British Land, has announced that they are leading the redevelopment of London’s Euston Tower. Built in 1970, the commercial high-rise was viewed as a cutting-edge office space. However, changing tenancy needs have seen a gradual reduction in its inhabitants, leading to the building’s vacancy in 2021.

The aim for the renewed Euston Tower is to transform it into a pioneering, welcoming, net-zero workspace in the heart of London’s Knowledge Quarter. The project falls in line with the sustainability goals and expertise of British Land, the Greater London Authority and Borough of Camden, and 3XN GXN. As noted in a release, the joint vision for the project sets out to lead the way in low-carbon retrofit and construction techniques, as well as using inclusive design to support the workspaces and local community.

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.

UN Secretary-General calls for significant changes to the cement industry ahead of 2050

2023-06-15T19:38:00-04:00

In an address to the Global Cement and Concrete Association in Zurich on Tuesday, United Nations Secretary-General António Guterres laid out his vision for changes to the industry he says are “fundamental to building a better world.”

Speaking to executives assembled in a “call to action,” Guterres asked for “concrete pledges from the concrete industry” before laying out his trifold ambits to ban coal-fired power in cement production, induce governments and industry to accelerate decarbonization efforts, and the furtherment of loftier emissions reduction targets and other plans in line with UN policy guidelines.

Seconding the Secretary's vision, the CEO of the Global Cement and Concrete Association, Thomas Guillot, added: “We applaud all the action our members are taking to implement carbon-cutting measures, and the latest data shows emissions are coming down. But many challenges remain, which we must overcome, if we are to achieve net zero, including enabling polices and regulations...

Perkins&Will revises firm-wide Green Operations Plan in the wake of latest UN climate report

2023-05-08T14:04:00-04:00

Perkins&Will has released an update to its Green Operations Plan in the wake of the United Nation’s latest Intergovernmental Panel on Climate Change (IPCC) report, which was critical of the strides global efforts have been able to make in avoiding a catastrophic 1.5° Celsius rise in temperature by 2040.

According to the firm, the update touches eight different project categories with three key “enhancements” that work to phase out plastic use while encouraging further decarbonization and acknowledging Indigenous cultures as sources of guidance and rightful stewards of the land.

McLennan, the chief sustainability officer of Perkins&Will, said in a statement. “Our enhanced Green Operations Plan offers specific guidance in just about every scenario that might unfold in our day-to-day business operations, from how we tra...

Toronto builders set their sights on (near) net-zero buildings by 2030

2023-05-04T15:24:00-04:00

Toronto builders have a challenging task ahead of them, and with a rapidly approaching deadline: constructing all new buildings with near-zero greenhouse gas emissions by 2030.

This goal falls under Toronto’s TransformTO Net Zero Strategy initiative, which aims to reduce community-wide greenhouse gas emissions in the city to net zero by 2040. The building mandate targets the sizable portion of carbon emissions that buildings account for. As reported by Storeys, data from The Atmospheric Fund (TAF) on carbon emissions in the Greater Toronto and Hamilton Area (GTHA) found that the building sector accounts for 44% of all emissions in the region.

One Canadian construction company, EllisDon, has reportedly been exploring ways to contribute to meeting these sustainability goals. With a large amount of building emissions originating from materials used within the construction process, the company began working with building and material sciences specialists. One shift includes altering cement usage by implementing alternative materials, nam...

Mass timber pedestrian bridge rises at Toronto's George Brown College

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...

Yazdani Studio's Caltech sustainability center is making progress

2023-04-13T15:28:00-04:00

Nearly one year after breaking ground in Pasadena, construction is in full swing for the Resnick Sustainability Center on the Caltech campus. [...] When completed, the new complex will serve as the physical hub of the Resnick Sustainability Institute, which has existing at Caltech since 2009.

Following a $750 million donation from The Wonderful Company owners Lynda and Stewart Resnick in 2019 to Caltech, plans to construct a new 80,000-square-foot research facility were put in motion. Designed by Yazdani Studio, the Resnick Sustainability Resource Center broke ground in May 2022 and is now rising along the west side of the school’s campus.

The building, distinct with its undulating glass façade and mass timber grid shell, will be home to critical research in solar and climate science, energy, biofuels, decomposable plastics, and more.

Appels Architekten designs prefabricated wooden home in Bavaria

2023-03-28T14:49:00-04:00

Zurich-based firm Appels Architekten has designed an open, simplistic family home in Bavaria, Germany, composed of wooden cubes.

Called “House by the Lake,” the home balances privacy and spaces for gathering. As detailed by the architects, this configuration allows residents to retreat or participate in communal living at any time.

All of the private rooms are housed within a sculpture of wooden volumes. Ample open space is made available both horizontally and vertically, drawing light into the house and offering views into the garden and surrounding environment. These features are maximized through the house’s generous ceiling height, light interiors, and expansive windows.

Energy department commits $6 billion to decarbonizing industrial manufacturing

2023-03-13T19:14:00-04:00

The Biden Administration announced a plan to help decarbonize the industrial manufacturing sector through a new $6 billion investment it says will eventually help lower emissions while signaling a newfound demand in the “marketplace for clean products.”

As part of the government’s largest-ever investment into industrial decarbonization, manufacturers of things like concrete, cement, and steel that are known to be heavy polluters will be bolstered by support through the new Industrial Demonstrations Program, which in turn advances grants to early-stage projects in line with the administration’s broader 2050 carbon economy goals.

The White House says grants will cover up to half of the costs for qualifying projects. The funding was made possible as part of the new Inflation Reduction Act and previous Bipartisan Infrastructure Law. Roughly one-third of all domestic carbon emissions come from the industries included in the decarbonization package, according to the Department of Energy (...

Sustainable design trends are already outpacing One Vanderbilt's once-lofty green goals

2023-02-16T17:07:00-05:00

It is also the rare skyscraper designed with climate change in mind. It holds a self-contained, catastrophe-resilient power plant capable of generating as much energy as six football fields of solar panels. The building captures every drop of rain that falls on it, and reuses that runoff to heat or cool its 9,000 daily visitors. But One Vanderbilt is also something else. It is already out of date.

New York City’s recent ban on fossil fuels is making the green technology built into the merely two-year-old KPF-designed tower obsolete in terms of energy sources, the NYT's Ben Ryder Howe writes. Foster + Partners’ nearby 270 Park project is cited as an example of the forthcoming delineation triggered by the new mandate.

Speaking to the Times, SL Green’s director of engineering Jonathan Wilcox said it remains “to be determined” which elements, including a set of powerful natural gas-burning turbines, will be replaced in unison with city and state guidelines in the future.

Architecture 2030's new CARE Tool helps measure the carbon reduction of retrofit projects

2023-02-15T14:38:00-05:00

A new metric measuring the amount of carbon reduced in reuse projects is changing the way practitioners of the built environment can quantify the success of retrofit projects of all types and sizes.

Architecture 2030’s new CARE (Carbon Avoided Retrofit Estimator) Tool is a way of providing valuable statistics that show the carbon savings of each project accurately and using a standardized methodology. Its tool was developed by Siegel and Strain Architects principal Larry Strain along with Architecture 2030’s Erin McDade and Goody Clancy’s Lori Ferriss and is already in use at several leading firms nationwide.

CARE Tool works by taking user inputs about energy targets and potential building interventions to estimate operational carbon emissions and embodied carbon emissions in each project.

According to the group: “Outputs are visualized as total embodied and operational em...

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.
