A German startup is offering a new way for old buildings to potentially reach net-zero status: adding a prefabricated second skin.
Ecoworks begins the process with a 3D scan of an old building, both inside and out, creating a digital twin. The model is then sent to suppliers and a factory, where most of the second skin is prefabricated, including windows, ventilation, and channels for pipes.
The resulting new envelope includes a modular roof with built-in solar panels. Construction workers can install a facade panel at the site in 20 minutes. A full building conversion, including replacing fossil-fuel-powered heat, can be done in a few weeks.
Ecoworks uses AI to identify buildings best suited to its approach. Simple, block-like apartment complexes are top choices, but the company plans to expand to schools and single-family homes. It also has plans to offer its services in other countries.

Zero Energy Buildings: When Do They Pay Off in a Hot and Humid Climate?
There’s lots of talk about zero energy as the next big milestone in green building. Realistically, how close are we to this ambitious goal? At this point, the strategies required to get to zero energy are relatively expensive. Only a few buildings, most of them 6,000 sf or less, mostly located in California and similar moderate climates, have hit the mark. What about larger buildings, commercial buildings, more problematic climates? Given the constraints of current technology and the comfort demands of building users, is zero energy a worthwhile investment for buildings in, for example, a warm, humid climate?
