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.

Hi SDL!

Our CM recently offered up the possibility of substituting Pozzotive into our structural and paving concrete mix (www.pozzotive.com) on a large public building. Apparently it is on a level with the cost of standard cement.
We are eager to reduce the project's embodied carbon, and this seems almost too good to be true.

Wondering if we can have a dialog on HVAC load calculation software... we are currently still using Trane Trace 700, but with the future migration to Trace 3D+ coming are looking into other options. Never used HAP but I haven't heard great things, and we dabbled in IES VE for a while, but went back to Trace since at that time there was no... 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?

Team SCL,

This was a tough week. My husband coined a phrase "20% laid off."

Unfortunately, 50% of our business is currently impacted by governmental orders stating that our work is non-essential. This is bitter-sweet. I certainly want people to be safe, but we've had to make some tough decisions and in the geographies that were... Read more

Anyone using the USG EcoSmart drywall? I'm writing a short product review and am looking for some quick feedback. I'm particularly curious about reduced greenhouse gas emissions and overall cost. Thanks! Brent

Has anyone heard of floating solar technology? I can't think of an application other than covering power plant retention or agricultural waste lagoons. Covering up the sun on a natural body of water and adding electrical wiring seems like a bad idea. I am curious though if others have heard of this technology and have other (unbiased) ideas...

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.

Hello SDL friends,

It has been an amazing opportunity to collaborate with so many of you through this group or through my work with Tally, the USGBC, ILFI, and in my role as an environmental researcher at KieranTimberlake. This is not so much a goodbye as it is a "hope to see you soon." I am making a shift away from building design into... Read more

I read a very misleading article on the AIA's website today regarding antimicrobials and the benefit of microbicidals in paint. It was written by a manufacturer, not a healthcare professional, and was not obviously labeled as sponsored content on the website. (I received the link in an email, which did label it as such).

Hello All-

  We have a K-12 school project that is using a R-60 flat roof assembly as an energy & costing benchmark (along with other energy efficiency measures but this is the relevant detail to our question).  The project mechanical engineer is not onboard with a number of our energy conservation measures and has been sharing...
