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...

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

A brief non-technical rant about OneClick LCA - from someone who is not actually USING the tool, but lobbying for its access.  Wondering if you all have better intel, or if it is just me.

We are working on a number of projects for which te teams are using OneClick LCA - for some cases it has a better international data set than others. ... Read more

Hey SDL,

I'm curious if anybody out there has developed specification language requiring a certain level of airtightness (as assessed via one or a series of blower door tests) for a commercial project when it is not going for a Passive House certification and a blower door test is not required by code--basically, something in the...

Just had a contractor call who said they had a university client interested in using natural-gas-fed fuel cells as an alternative to grid power in some applications.  They were interested in an intermediate scale: 300kW.

Anyone with any experience with these devices?

We have an MEP engineer that is calculating peak loads at about 6 times passive house levels on a large commercial building that is at or near passive house levels of insulation and air infiltration. 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
