We're looking to expand our design performance group - let Peter or me know if you have someone to recommend to us! Here's the description. 

CEUs are available for reading all the building-envelope product guides and primer. Click here to learn more and take the quiz.

Standard spray polyurethane foam (SPF) insulation is made using blowing agents with extremely high global warming potential (GWP), which can cancel out much of the potential energy savings from use over its life... Read more

With an urgent climate justice mission, AIA has the call open for volunteers to help shape our industry's action. COTE, the Codes + Standard Committee (one of the most important committees anywhere!), Board Committees (including the Committee on CLimate Action and Design Excellence - CCADE)  and the Strategic Council have openings.

Hello, what acceptable levels of air quality are you using to evaluate natural ventilation strategies for your projects?  In our Living Building we only open windows when PM10, PM2.5, etc. are within LBC and WELL limits.  In a seasonally smoggy urban environment, this limits how often we can utilize natural ventilation even if the outside...

This might be going down a rabbit hole, but in moving to California this year I noticed that "zero net energy" (ZNE) is the standard term, whereas "net zero energy" (NZE) was more common back east. The DOE's 2015 definition (below) uses "zero energy building" (ZEB), which to me implies a building uses no energy at all.

Here are the... Read more

Is anyone else working on a project doing Living Building Challenge v4.0 Energy Petal? We're working through the Imperative 08 Net Positive Carbon Resiliency Strategy requirements that ask for the project to be habitable for a week in the event of an emergency. We're curious how others are defining "habitable" and what systems assumptions... Read more

Gurus -

I'm looking for (or to build) a set of US district energy projects for developer-led mixed-use/residential neighborhoods/districts.  Does anyone have a resource for this or have started something similar?   

I am not a member of IDEA but utilize their site quite often. Any other resources come to mind?  I'd be happy to... Read more

Good morning SALs! Nicole's survey on restrooms inspired me to post a survey of my own.

I’ve been trying to stay useful lately. I've been posting new writing on the industry, much of it complimentary, over on Roberts’ Green Letter. (Yesterday I posted the mission statement, explained via brand-new-puppy pics.)

I have a 1-minute... Read more

I'm looking to compare using an electric tower crane vs a diesel generated tower crane.  I've got the average gallons/hour for the size of crane I'm looking at, but when I reached out to the crane manufacturers, they can only tell me what size electric supply I need to provide, not the kWh usage for the cranes.  I know that it varies depending...
