So, if you're thinking of someone to invite or come across... Read more

Hi all!

I'm working on my first energy positive / passive house multifamily building and trying to figure out the trash/recycling chute. I am curious what solutions you have employed to make the trash chute air tight? We have excluded the whole chute from the envelope. Do you use airtight doors (and which ones?) at each floor trash/... Read more

I am looking for case studies/trying to identify buildings using concrete mixes with upwards of 30% replacement of cement by SCMs.  I've been in conversations with some structural engineers who are interested in lowering embodied carbon in upcoming projects, but would like to see examples of where this level of replacement has been successfully...

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...

We have several projects that are small enough that we don't hire consultants to run energy models. I just received permission to do some training so that I can run these models myself. I am looking at doing this training on eQuest:

Hi all,

I'm sure many (most? all?) of us have heard the changes to LEEDv4's energy standard are coming. If this is news to you, info on the balloted measures that have passed is available online here: https://www.usgbc.org/articles/leed-v4-energy-update-approved-member-ballot.

The opportunity for water savings from installing efficient toilets, and from toilet replacement, is significant. In addition to improvements to the traditional gravity system, pressure- and vacuum-assisted flushing systems are available that offer superior performance—albeit often with some increase in flushing noise.

Colleagues,

As we all know, ventilation rates must be kept the same between the LEED Baseline and proposed energy models. However, we're aware of projects that have been able to claim energy savings associated to reducing ventilation using systems like Aircuity. 

Have any of you successfully claimed credit for reduced airflow due... Read more
