I've been seeing Armstrong's DC flexzone ceiling system at Greenbuild for many years. I'm working on a net zero project with LED lights and solar panels. In theory, the transmission losses in going from DC power from panels to AC for the building to DC for the lights would be eliminated. But does anyone actually have experience using this...

Hello all,

We are looking at ways we can use our specs to reduce toxicity in projects and one step towards that goal may be to require RoHS compliant lighting, switches, alarms, meters, etc., as required by the Small Electrical Components exception in the Living Building Challenge. Based on LBC projects I have been involved with, it... Read more

Prefabricated, or modular, buildings can provide environmental advantages over conventionally constructed buildings. They are built in factories where manufacturing and cost can be tightly controlled, so materials are kept out of the elements, there is less waste, and thermal properties and air sealing can be enhanced. There are also fewer... Read more

We suspect one reason is that he is figuring a 50% efficiency level for the ERV. We are showing him ERV systems with 80-90% efficiency, but they... Read more
