Lloyd Alter on some of the difficult tradeoffs inherent in green building

Once again, some thought provoking writing from longtime sustainable architect and Treehugger columnist Lloyd Alter: The best way to have our buildings use less energy is to insulate them really well. But for a long time, I have also been writing about the problems of insulating with plastic foam, even writing that Polystyrene insulation doesn’t … Continue reading Lloyd Alter on some of the difficult tradeoffs inherent in green building

Proof of Concept: Ultra-thin, insulated concrete roof with embedded PV

Once again, the incredibly brilliant minds at Eidgenössische Technische Hochschule Zürich (ETH Zurich) have announced innovative processes and materials for a better built environment. Phys.org has the story: Researchers from ETH Zurich have built a prototype of an ultra-thin, curved concrete roof using innovative digital design and fabrication methods. The tested novel formwork system will be … Continue reading Proof of Concept: Ultra-thin, insulated concrete roof with embedded PV

3D-Printing an entire building is reality, no longer just a theory

Researchers at MIT have confirmed that the future of the A/E/C industry is now in fact here. In the proof-of-concept, a vehicle of sorts, moving along a track, carries a robotic arm that utilizes a precision-controlled nozzle to place a variety of materials including spray foam insulation and concrete. ScienceDaily reports: Structures built with this system could … Continue reading 3D-Printing an entire building is reality, no longer just a theory
