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.

For any of you who are already tracking your Scope 1, 2 & 3 emissions: Do you do so through a program (like the Carbon Disclosure Project) or do you have an in house excel file or ???? I'm looking for a good template and am open to suggestions.  Looking for what you like and what you find challenging.  Thank you.

Hi there Hive Mind! Hope everyone's doing well and staying cool in the heatwave all over.

An engineer on one of my projects reached out about contact switches for operable windows that are empowered to shut down the associated FCU in dormitory bedrooms when the window is open. This functionality allows the FCU to run at something like... Read more

Hello, does anyone have experience with thin film solar? We're looking to add it to a city wide bus station application. Thanks!

Does adding solar panels reduce a building's EUI?

Existing operational use of a building is 80 kBtu/sf/year. When we add solar, it will change the source of energy but does not change the usage.

My understanding is that the EUI does not change, but it would be good to hear from others.

It's energy consumption at the point... Read more

We have a client for whom we are designing a very high performance manufacturing facility, and they want to communicate their building's performance both dynamically and in real-time within their lobby for guests and staff.

We would like to mine the wisdom of this group to see what recommendations we can muster regarding high quality... Read more

Good daylighting intentions can end up increasing glare and solar heat gain.

BuidlingGreen-Approved Lightshelves

We look for lightshelves designed to reflect direct sunlight onto the ceiling, turning what could potentially be glare into diffuse, ambient daylight that penetrates deep into the interior of a building.

Are FSC glulams available? By many manufacturers? Which ones?

Hi, this is a somewhat niche/specific question - we are working on an all-electric school (middle and high school) that includes a chemistry lab. The lab was going to have portable sources for flame experiments, but there is concern that the portable sources would be unsafe for middle school students, so they are asking for a hard-pipe natural...

Does anyone here have a draft spec for low embodied carbon concrete they could share? I see the GSA has a standards sheet with MGWP limits, but we are hoping to actually specify the mix for upcoming projects.
