I'm curious who in this group has used ASHRAE Standard 209-2018, Energy Simulation Aided Design for Buildings except Low Rise Residential Buildings?

We've used it internally (minimally) as a reference to help better communicate the goals and activities involved with energy modeling at various phases of design. But it seems like there's... Read more

Hi SDL: Please see attached letter to USGBC about the urgent need to address climate change in the next iteration of LEED v4.

And it has also become clear that the steep... Read more

Hi amazing people!

Most of our projects are now going with some form of gender neutral/all-gender/inclusive toilet rooms or those that can easily be converted to such. With no urinals, we lose 3 LEED points because urinals are very water-efficient. With urinals, it's not as pure a solution. Do you all just take a hit on the LEED points,... Read more

I have been watching LEED Zero for a while, and have appreciated certain things, but one thing I think is an absolute disaster is their allowance of mainline RECs for claiming Zero Energy and Zero Carbon performance.  I just asked this question on the LEED Zero webinar, and the panelist basically said, "it's part of LEED Zero, therefore it is...

Hi all - I can't remember this topic being posted recently so here goes. With fossil fuel free finally being something our clients are increasingly wanting to know about, we are stuck on diesel generators. They have several advantages including: cost, inherent refillability from a truck, reliability, and are the market standard. In initial... Read more

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.
