Montana has become the first state in the nation to adopt broad-ranging regulatory approval for the use of 3D printing in construction. The state’s building code regulators recently voted to approve local contractor Tim Stark’s request to 3D print walls as an equal replacement for either... View full entry
Engineers at RMIT University have developed a method to use disposable personal protective equipment (PPE) to make concrete stronger, providing an innovative way to significantly reduce pandemic-generated waste. [...]
Joint lead author, Dr Rajeev Roychand, said there was real potential for construction industries around the world to play a significant role in transforming this waste into a valuable resource.
— Science Daily
According to the RMIT researchers, an incredible 54,000 tons of PPE waste has been produced daily since the start of the pandemic. "With a circular economy approach, we could keep that waste out of landfill while squeezing the full value out of these materials to create better products &mdash... View full entry
A team of Washington State University (WSU) and Pacific Northwest National Laboratory researchers has discovered a method to create stronger cement by putting nanoparticles from shrimp shells into cement paste. The innovation could lead to reduced seafood waste and lower carbon emissions from... View full entry
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... View full entry
A quartet of undergraduate engineering students at the American University in Cairo has developed self-luminescent concrete they say is a possible offset to the material’s poor environmental performance. Working under the stewardship of Professor Mohamed Nagib AbouZeid, the students were able to... View full entry
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. — Building
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... View full entry
Archaeologists of the Instituto Nacional de Antropología e Historia (Iphan, the Mexican federal bureau that oversees cultural heritage projects) have unearthed a remarkably well-preserved Maya city in the Yucatán peninsula near Merida while examining a construction site for archaeological artefacts. — The Art Newspaper
The site is called Xiol, which is believed to have been occupied by more than 4,000 people between 600 and 900 AD. It consists of nearly 100 structures with features related to the Mayan Puuc style, an architecture characterized by carefully-cut veneer stones set onto a concrete core, with... View full entry
Here’s a sobering fact: The building sector is dragging down global efforts to reduce carbon emissions. [...]
The good news is that, according to the report, up to 61% of building emissions could be cut by 2050, and we have all the solutions at our disposal today, from passive cooling technologies and denser multifamily homes to retrofits. All we need to do is implement them—or better yet, introduce regulations and policies to will them into implementation.

The latest report by the Intergovernmental Panel on Climate Change (IPCC) found that emissions from buildings doubled between 1990 and 2019 despite the widespread adaptation of environmentally-friendly construction methods and materials like recycled concrete. Increases in population and the total... View full entry
Two buckets. That’s all that was left at the end of the day when Nexii, a concrete alternative start-up, tore down one of its first demonstration projects. A 700-square-foot showroom and model home displaying Nexii’s building technology was constructed in 2019 near Vancouver to prove the buildability of the new material, which has far lower emissions than conventional concrete. — Fast Company
Combining their sturdy panel-based construction system with their concrete alternative, Nexiite, which produces about 35% lower carbon emissions than conventional concrete, Nexii was able to deconstruct the showroom in six days, saving almost every part of the building for future reconstruction...

Last year Japan’s Serendix Partners caught our eye with its concept for spherical, 3D-printed houses. Not only do they have a stylish, futuristic appeal, Serendix wants them to be low-priced enough to make the cost of buying their 3D-printed houses comparable to that of a budget-friendly new car. — Japan Today
From start to finish, the small, egg-shaped dwelling, called the Sphere, took 23 hours and 12 minutes to build. The home, which won NASA’s 3D-Printed Habitat Challenge in 2015, was designed by Japanese architect Masayuki Sono. It was constructed in the city of Komaki in Japan’s Aichi... View full entry
The German University of Technology in Oman (GUtech) along with Danish 3D printer producer COBOD and Mexican cement company Cemex has completed the largest 3D printed building in the world made with real concrete. Located in the Omani capital of Muscat, the 2,100-square-foot structure was... View full entry
ETH Zurich has unveiled details of their latest investigation into advanced building materials in construction. The project, titled FoamWork, explores how foam 3D printing can assist in creating concrete formworks. The initiative saw ETH Zurich’s Digital Building Technologies team work in... View full entry
Ryuichi Sasaki/Sasaki Architecture has returned to the international spotlight with its winning entry for the mixed-use portion of this year’s Architecture MasterPrize that adds an iconic new touch to one of Tokyo’s oldest neighborhoods. Located in the city’s Minato ward, the... View full entry
A fascinating addition to the Chinese cultural program has come online this week with the completion of OPEN Architecture’s Chapel of Sound in Chengde, Hebei Province. Overlooking the ruins of one of China’s most important historic sites, the Ming Dynasty-era Great Wall, the concert hall... View full entry
Architects, officials, and villagers confirm the trend: People are discarding traditional materials, mostly mud, in favor of concrete, as soon as they can afford it. As living standards increase making concrete more accessible, some of the world’s hottest, poorest landscapes are rapidly morphing from brown to cinder block grey. — National Geographic
Architects like Francis Kéré have been attempting to buck the trend of using concrete by experimenting with upgraded versions of terrestrial materials like mud bricks that simultaneously provide tools for community-building in developing countries like Burkina Faso. Facade detail of Kéré... View full entry
