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,

We’re looking for Design Energy Code Equivalents for Chinese commercial energy codes. Do any of you have  any good sources? I’ve only found data comparing ASHRAE 90.1 2013 to the Chinese Code at that time. We understand the Chinese code require a 65-75% energy savings over the baseline but don’t have good information for defining... Read more

Vapor retarders are meant to protect our building assemblies from getting wet, but they can also slow drying, contributing to mold and structural degradation.

After reviewing BP language today with internal staff, we realized we'll need to add a glossary to explain industry jargon and technical terms that might not be widely used. I'd like to consolidate those terms onto one web page, a glossary. This probably should be on the list with the best practices, and it will need its own page. Thanks!

Greetings Gurus!! I'm super excited to invite you all to help each other :)

As many of you know, BuildingEase (a completely free tool!) has been born this year, the newest function we just launched is the Crowdsourcing function.

Hey Peer Network! Curious, if we can crowd-source a solution here for the pervious pavers at our Omaha office (climate zone 5A). Apparently over the years we've tried to add different kinds of fill here (gravel) but it keeps... disappearing. Any recommendations with either a replacement product or fill item?

So every year about this time I get to spend many lovely moments with our AIA 2030 Reporting data. In order to make the data useful the CBECS baselines/National baselines aren't great in telling us how we did.

For about half our 15 projects that we report in the average year - performing arts, convention, data science schools, etc - a... Read more

Hello, all! I'm working on an in-depth article about adaptive thermal comfort. I'm looking for interviewees who have real-world experience of working with ATC on a project, including occupant feedback. If you have that kind of experience, I'd love to hear from you!

This is happening on a very tight timeline, so please get in touch with... Read more

I'm definitely slow on the draw here, but happy to be congratulating you, Allen! What a great recognition of your work as a firm! And I love that the story about it highlights the firm's diversity.

Also worth noting--just 'cause no one here has said it yet--how cool it is that Ed Mazria won the Gold Medal this, and that AIA updated it's... Read more

Asking for a colleague:

"Have you ever had a large number of fire retardant tarps used to temporarily enclose a building during construction? Do you know of any solutions for recycling/reusing them or another product that doesn't use toxic fire-retardants that meets the performance criteria?"

I think we've all seen poly or fabric... Read more
