Hi all,

I am working on a Div 01 sustainability spec section for our firm to include by default on all projects. I've been finding a lot of great sample language out there for embodied carbon measures and material transparency (huge thanks to anyone here who had a part in developing those resources). 

One thing I'd like to include... Read more

Hey there hive mind,

We went looking through LEEDuser to try and find some direction and didn't find much so I thought I'd bring my team's question here to all of you smart people. We're working on a non-combustion central plant tied to a geothermal field and grid electricity. The project has cooling towers and their associated chemical... Read more

Hi friends, 

Before i forget, here is the checklist I mentioned yesterday that got such a positive response in our office - again it came about after i was asked (for the Nth time) to write a sustainability description for a concept proposal/ RFP that I was not a part of and frankly didn't have a lot going for it. So it's framed as "you... Read more

I was recently asked if there is a way to quantify financially what one MT eCO2 might be worth in the context of a building owner reducing their own carbon emissions.  How do you put a dollar value on those reductions?  Does anyone have experience with that or can you point me to the correct resource to answer this question?

Hi All,

I'm teaching a class this semester at CU Boulder on Zero Carbon Buildings and Cities (a new class that I'm making up as I go). The hardest part, I'm finding, is locating some good materials that cover the basics of energy efficiency for non-building engineers or designers (we are energy and sustainability generalists in this...

Embodied carbon in products and existing buildings. What does LCA tell us about renovation vs. new construction and material choices?

Guiding Questions: 

I am working on a new community development in St. Paul that is striving to achieve net-zero energy. We are able to get there mathematically by using the extra generation on light industrial rooftops to offset medium-density housing energy use (all buildings are anticipated to have different, private owners). However, this puts us over... Read more

I’m curious what people think.

Hi all,

My office is looking at some certification options for our upcoming renovation. One thing the management team asked me that I don't have a solid answer for is, do WELL certified spaces typically go through with recertification and everything it entails, or are they doing the upfront work to get certified and then letting it lapse...

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
