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...

Snøhetta designs hemp-based lighting product inspired by 1970s ateljé Lyktan line

2024-03-13T12:02:00-04:00

Snøhetta has designed a line of lighting products for Swedish lighting manufacturer ateljé Lyktan.

The project began as an exploration into how ateljé Lyktan’s products could be reimagined using locally sourced materials with a smaller ecological footprint. Initial experiments with pine cones and coffee grounds led to the choice of hemp fiber, which the...

Researchers look at the possibilities of wood fly ash by-products as an alternative in rammed earth construction

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

New findings published in the journal Construction and Building Materials from a team of materials researchers working at the University of British Columbia Okanagan's School of Engineering have demonstrated the sustainable qualities of using wood fly ash by-products as alternatives to traditional concrete additives.

The study was undertaken in light of some recent popularity of rammed earth construction in the architectural field, an ancient form of building whose mastery has propelled the 2022 Pritzker Prize winner Diébédo Francis Kéré and several others to prominence parallel with the industry's fight against climate change.

"Everything old is new again and that is precisely why we've been investigating rammed earth construction," Dr. Sumi Siddiqua explained to the UBCO news outlet. "There is an increasing demand for sustainable building products here in Canada and around the world, and materials like fly ash are just the start of a new and important trend."

Siddiqua’s team was...

Researchers use cellulose and algae to create 3D printed architectural material

2024-02-09T13:46:00-05:00

Researchers at Chalmers University of Technology in Sweden have published their study into how materials made from nanocellulose and algae can be used as sustainable architectural materials. The research, conducted in collaboration with the Wallenberg Wood Science Center, “shows how the abundant sustainable material can be 3D printed into a wide array of architectural components, using much less energy than conventional construction methods,” according to the team.

Nanocellulose, molecules consisting of hundreds or thousands of carbon, hydrogen, and oxygen atoms, are already used in biomedicine to 3D print scaffolds for tissue and cell growth but have never been used in an architectural material. The researchers, therefore, mixed nanocellulose fibers and water with an algae-based material called alginate to produce a 3D printable material with architectural uses in mind.

“For the first time...

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...

ETH Zurich researcher develops 3D printed insulation foam using recycled materials

2023-12-01T11:48:00-05:00

ETH Zurich has published details of new research into lightweight building components produced using 3D printing. Led by doctoral architecture researcher Patrick Bedarf, the Airlements project centers on cement-free mineral foams derived from recycled industrial waste.

Working within the institution’s Digital Building Technologies group led by Professor Benjamin Dillenburger, Bedarf’s project emerged from a doctoral thesis on lightweight insulating construction elements, and how complex shapes could be manufactured with fewer material inputs. Bedarf ultimately deployed a sustainable insulation material produced by the ETH spin-off FenX using recycled industrial waste.

FenX’s mineral foam material is mostly made from fly ash, a waste product from industrial blast furnaces. Bedarf’s process then deploys 3D printing to shape the material into bespoke building parts without the need for formwork, which is traditionally only partly reusable and more time-consuming.

“Without automation, ...

University of Maryland researchers develop 'cooling glass' that can redirect a building's heat into space

2023-11-17T11:54:00-05:00

Researchers aiming to combat rising global temperatures have developed a new 'cooling glass' that can turn down the heat indoors without electricity by drawing on the cold depths of space. The new technology, a microporous glass coating, can lower the temperature of the material beneath it by 3.5 degrees Celsius at noon, and has the potential to reduce a mid-rise apartment building's yearly carbon emissions by 10 percent.

The technology was developed by a research team at the University of Maryland, led by Distinguished University Professor Liangbing Hu in the Department of Materials Science and Engineering. The coating functions by reflecting up to 99% of solar radiation to prevent buildings from absorbing heat. It emits heat in the form of longwave infrared radiation into space. The phenomenon is known as radiative cooling, in which space serves as a heat sink for the buildings.

According to the research team, their glass is more environmentally stable than previous attempts at cooling coatings. The glass can be applied to a variety of surfaces, such as tile, brick, and metal, which makes it scalable and available for wide use. The researchers envision the new material as a key contributor to the solution to climate change due to its potential to reduce a structure’s energy usage and carbon footprint. The team is now working to further test the glass and understand its practical applications.

SOM unveils new algae-based Bio-Blocks technology at the Chicago Architecture Biennial

2023-09-29T14:01:00-04:00

Skidmore, Owings & Merrill (SOM) has debuted a new concrete alternative material as part of its participation in the fifth Chicago Architecture Biennial (CAB 5), which is taking place now through February 11th at multiple locations citywide.

The firm’s Bio-Blocks technology is being presented as a replacement for traditional Concrete Masonry Units (or CMUs) and can reduce emissions on a project by up to 8% if used at scale. The blocks were fabricated with help from Prometheus Materials using microalgae that were then subject to the company’s patent-pending photosynthetic biocementation process. The results seen therein offer a one-metric-ton total offset, according to the product team.

Coffee grounds can make concrete a little stronger, too, according to a new RMIT study

2023-08-28T11:58:00-04:00

Engineers in Australia have found a way of making stronger concrete with roasted used-coffee grounds, to give the drink-additive a "double shot" at life and reduce waste going to landfills. [...] Published in the Journal of Cleaner Production, the study by RMIT engineers is the first to prove that waste coffee grounds can be used to improve concrete.

The study found that three different coffee ground samples each increased their concrete pour’s compressive strengths by up to 30% once their organic compounds were broken down through pyrolysis. The discovery could go a long way in combatting issues such as food waste and the carbon impact of concrete’s still rampant use as a construction material worldwide. RMIT will follow up with additional mechanical and durability tests on the same samples.

"Our research is in the early stages, but these exciting findings offer an innovative way to greatly reduce the amount of organic waste that goes to landfill," the paper’s co-lead author, Dr. Shannon Kilmartin-Lynch, explained. Discarded PPE may also have a stirring second life in construction, according to a separate study the same team of researchers published last year.

MIT researchers create strong, ultra-light architected materials using kirigami techniques

2023-08-24T14:02:00-04:00

Researchers at MIT have developed a lightweight architected material inspired by the cellular structures found in natural materials such as honeycombs and bones. Produced with techniques borrowed from the Japanese kirigami paper-cutting technique, the strong metal lattices are lighter than cork while also holding customizable mechanical properties.

Using kirigami techniques, the MIT team led by Professor Neil Gershenfeld of the Center for Bits and Atoms has produced plate lattice structures on a larger scale than was previously possible. The structures are described as "steel cork" by Gershenfeld due to their lightweight nature combined with high strength and stiffness.

“To make things like cars and airplanes, a huge investment goes into tooling. This manufacturing process is without tooling, like 3D printing. But unlike 3D printing, our process can set the limit for record material properties,” Gershenfeld said in a statement.

University of Michigan researchers detail new 3D printed upcycled sawdust material for formwork

2023-08-22T13:09:00-04:00

A recyclable alternative material developed by researchers at the University of Michigan Taubman College of Architecture and Urban Planning’s Digital Architecture Research & Technology (DART) Laboratory is providing builders with a more sustainable way of applying concrete casts in the construction process in order to cut down on waste and the environmental impact of projects using the method.

The fully biodegradable BioMatters material is made from sawdust that’s collected and used via robotic 3D printing in the formwork of buildings, an essential element that currently constitutes 40% of all concrete-related construction expenses industry-wide, according to DART.

Termite mounds hold secrets for energy-efficient buildings, researchers find

2023-05-30T10:58:00-04:00

Researchers have uncovered a methodology for reducing energy consumption in buildings by studying the structure of termite mounds. Led by Lund University’s Dr. David Andréen and Nottingham Trent University’s Dr. Rupert Soar, the research suggests that the properties of lattice networks in termite mounds, known as an ‘egress complex,’ can be copied to optimize the interior climate of buildings.

“Here we show that the ‘egress complex’, an intricate network of interconnected tunnels found in termite mounds, can be used to promote flows of air, heat, and moisture in novel ways in human architecture,” said Andréen about the study, which was recently published in Frontiers in Materials.

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...

400 hanging mushroom bricks used in Studio Link-Arc’s Shenzhen Biennale installation

2023-03-22T11:27:00-04:00

New York City firm Studio Link-Arc has created an installation in Shenzhen formed from 400 hanging mushroom bricks. Titled 'Mushroom Brick Pyramids,' the project was created for the 2022 Shenzhen Biennale, which adopted the theme ‘More than Human Adventure.’

The resulting scheme was set within a converted old brewery, which included a gallery space between the continuous concrete frames. Beneath the 400 hanging mushroom bricks, a pool was created to provide a moist microclimate, while the indoor-outdoor nature of the space allowed for additional moisture...

Is shipping container architecture really sustainable?

2023-03-09T13:50:00-05:00

Ultimately, removing containers from the circular economy by retrofitting them into usable spaces could put a strain on the industry and result in the need to use more iron ore, causing even more harm to the environment. Even as the tiny house movement continues to gain popularity and shipping containers are beloved both for their aesthetic appeal and supposed sustainability, it’s worth asking if they’re the right material for this purpose.

While shipping containers do generally keep project costs down owing to labor hours saved, the fit-out of their interiors can add between $20,000 and $150,000 to each construction. Materials such as spray-on foam insulation used in making a container design habitable are rarely among the market’s most sustainable options. The lead-based paint coating typically applied for their seafaring protection against salt water only adds to the toxins produced while the insulation is applied.

University of Edinburgh professor Richard J. Williams said their prevalence was emblematic of “hipster modernity” in a popular 2019 essay, adding “they’re great for doing what they were designed to do, which is transporting stuff. A simple technology, they have helped facilitate global trade like no other. But they’re designed for things, not people."

Nevertheless, as FastCompany reported, the market for container homes is expected to grow to $67.96 billion by the year 2026.

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...

IAAC/WASP team creates ‘solid and expressive’ 3D printed wall made from earth

2023-02-13T13:17:00-05:00

Barcelona’s IAAC has collaborated with Italian 3D printing company WASP on the creation of a 3D printed earthen wall. The element was printed from a mixture of clay and rice fibers, with interlocking timber beams providing support for stair and floor structures.

The 15.7-inch-thick wall was printed in 40 hours using 70 cubic feet of material. Printed in horizontal layers with voids left for the placement of cantilevering timber elements, the team describes their method as one that can “confer both solidity and aesthetic expressivity.”

The prototype was printed using WASP’s modular 3D printing system titled ‘Crane WASP.’ The machinery is composed of a main printer unit that covers an area of 538 square feet by way of a radial mechanical arm, similar to the operation of a traditional construction crane. The Crane WASP system has also been used to deliver the Mario Cucinella-designed TECLA raw earth home which we reported on in 2021.

University of Chicago researchers develop ‘chameleon-like’ material that can regulate buildings by changing from solid to liquid

2023-02-08T12:30:00-05:00

Researchers from the University of Chicago’s Pritzker School of Molecular Engineering have published details of a new material that can auto-regulate its environment by changing its infrared colors and liquid-solid state. In the future, the ultra-thin material film could be added to a building’s thermal facade in order to reduce the need for HVAC systems.

“Nearly 30% of the energy consumption and 10% of the greenhouse gas come from buildings,” says Chenxi Sui, a member of the research team whose findings have recently been published in the journal Nature. “Looking for diverse approaches to maintain a comfortable building temperature becomes a key point to creating a sustainable and carbon-negative future. Instead of controlling the indoor temperature in conventional ways, we keep wondering: Can we treat the building like the human body?”

In 2022, breakthroughs in 3D printing and material science challenged how we build, and what we build with

2022-12-22T08:00:00-05:00

2022 was another productive year in laboratories across the United States and beyond, as colleges, manufacturers, and startups strove to challenge the orthodoxy of construction materials. While teams of students and researchers at institutions from Virginia Tech to ETH Zurich sought to push the boundaries of traditional materials such as timber and concrete, disruptive startups sought to broaden this palette with the introduction of everything from recycled plastic to mushrooms.

These investigations into material science were matched by equally impressive advancements in construction processes, marking 2022 as a year that asked ‘how’ we build as well as ‘what’ we build with. As with previous years, 3D printing featured heavily in 2022’s highlights of intriguing construction innovations, be it new nano-structural 3D printed systems that can sense their own movement, or a growing portfolio of real-world 3D printed homes which signal the arrival of the once-novel process as a viable ma...

Hempcrete has been added to the U.S. building code appendix

2022-12-05T15:22:00-05:00

For many years, industrial hemp was illegal in the US due to hemp’s association with drug use, despite the fact that it does not contain more than 0.3 percent THC [...] Building residential homes with hempcrete was therefore effectively outlawed until 2018, when the Farm Bill distinguished between hemp and cannabis plants. Then, in September 2022, hemp building materials were added to the model US residential building code, paving the way for legal use in 2024.

The International Residential Code (IRC) accepted a modified appendix in September that some are hopeful could be a catalyst for further adaptation throughout the building industry. Builders for Climate Action spokesman Chris Magwood says its greatest potential lies in commercial construction, though applications within residential design do present inherent challenges owing to drying times, insulation R-Values, and other factors.

Previously on Archinect: Hemp is about to take an outsized role in the building industry's push to go green

"I don't think that hempcrete will ever play a large role in the residential market," Magwood recently explained to Treehugger. "The fact that it is a composite material that uses a lime-based binder means that it is less insulative than other options and more expensive. Somebody has to mix, form, and cure the material, whether that happens on-site or in pre-fab units or blocks. To meet basic minimum code requirements in colder climates requires at l...

Carmody Groarke develops bricks made of city waste for museum facade in Ghent, Belgium

2022-11-18T04:00:00-05:00

Waste from the city of Ghent, Belgium, is being turned into the building blocks of a major cultural institution. For a renovation and expansion of the Design Museum Gent, an innovative new recycling process is turning old bits of broken concrete and glass into the bricks that will cover the museum’s exterior.

The Gent Waste Brick was designed by London-based practice Carmody Groarke in partnership with materials designers BC Materials and Local Works Studio. Together, they developed an energy-saving method that takes ground construction waste materials, mainly crushed concrete, masonry, and glass, from demolished buildings and infuses lime to form dry-cured bricks. This approach utilizes local materials rather than extracting clay or importing mass-produced bricks from elsewhere. As reported by Fast Company, the materials were collected mostly from within five miles of the museum.

The bricks are formed in a shipping container-sized mobile processor and then dry cure for 60 days, a much less energy-intensive process than traditional brick production. As a result, they will reportedly produce a third of the amount of carbon dioxide over a 60-year lifespan than a conventional brick. For the museum expansion, the Gent Waste Bricks will be used on the museum's facade, which is expected to co...

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.

ETH Zurich students and researchers build prototype 3D printed 'eggshell pavilion'

2022-10-03T11:17:00-04:00

A group of faculty and students from ETH Zurich has completed a prototype architectural pavilion whose production merges 3D printing with computational design. Unveiled at the Vitra Design Museum in Germany, the Eggshell Pavilion’s development seeks to demonstrate how "digital design techniques and robotic 3D printing can enable the creation of freeform concrete structures out of recycled ultra-thin formwork."

The pavilion’s design and fabrication was driven by design algorithms that generated both the geometry of the structure and the fabrication data needed to 3D print the pavilion. The team believes that this combination of computational design and robotic fabrication can unlock the potential for designers to shape concrete elements efficiently, avoiding traditional labor-and-cost-intensive formwork processes.

Cornell professors are building the first multistory 3D printed structure in the U.S.

2022-09-22T11:25:00-04:00

Construction is underway in Houston on the first multistory 3D printed building in the United States. Designed by two assistant professors of architecture at Cornell’s College of Architecture, Art and Planning (AAP), the two-story, single-family home merges 3D printed concrete with a traditional timber frame, creating what designers Leslie Lok and Sasa Zivkovic believe is a precedent for future 3D printed multifamily and mixed-use developments.

When completed, the 4,000-square-foot home will contain three bedrooms, three bathrooms, and a two-car garage, while a 40-foot-high chimney will make the home one of the tallest 3D printed structures in the U.S.
