Championing the

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.

I'm hoping for some help answering the question of whether buildings/communities should pursue net-zero energy on site versus investing in new renewable energy (i.e. through the electric utility) that can be built at a more efficient scale elsewhere in the state. Our utility is asking us this question as we are working through how to get the... Read more

Hello SDL Leaders,

Over the past month, I have been working with ILFI to navigate the question of residuals in LBC compliant products vs. products reporting for a Declare label.

Through our conversations, it came to light that ILFI considers the LBC Red List threshold to be 10,000 ppm, rather than the 100 ppm written into the... Read more

I am putting together a presentation for our local AIA conference specifically about shading devices / dynamic glazing / dynamic shading and wonder whether any of you have experience / feedback from projects that used a dynamic system - exterior operable shading or dynamic glazing (like View, Sage).  Any post-construction / post occupancy...

Related to some recent questions on site-specific sun/wind analysis and early energy modeling tools, are there any tools that account for nearby topography (like bluffs) or large buildings/vegetation in energy calculations? Or favorite methods to estimate its impact particularly during early massing studies?

Thanks,

Rachel

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

Hi everyone,

Since I know we have a lot of talented people in this group, I'd like to reach out to those of you based in Los Angeles and see if anyone is interested in talking at an upcoming Living Building Challenge collaborative event.  The topic of the meeting is "Selecting Healthy Materials 101: From the perspectives of...

Hi Shane and Dennis,

What return address should we use for BIT User forum notification emails?  Ben suggests something like no-reply@bit-user.org but whatever you like is fine.

Once you decide, please let us know who controls the domain name (e.g. bit-user.org or bitbuilding.org).  Ben will send them instructions for editing the... Read more

This month on our Sustainable MEP Leaders call we were asked what resources would be suggested for advancing integrative design.

Two books immediately came to mind for me:

How Building Learn, by Stewart Brand
