Textiles have some of the worst environmental records of any product found in our buildings. Textile production uses a number of hazardous chemicals and pollutes water; and its environmental impacts often affect our most vulnerable populations.

BuildingGreen favors textiles made using fibers and manufacturing processes that have low... Read more

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...

Does anyone here have a draft spec for low embodied carbon concrete they could share? I see the GSA has a standards sheet with MGWP limits, but we are hoping to actually specify the mix for upcoming projects.

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

Hello Sustainable Community Design Leaders,

The SDL Winter Summit (Jan 23-25, Tempe AZ) has a few spots still open, so we are excited to invite SCDL members to join! This is an opportunity to plug into the conversations happening in the Sustainable Design Leaders group, plus a possible chance to carve out some in-person SCDL time.

Something we seem to be seeing a lot in our market recently are projects split into multiple packages - footing / foundation, C&S, and then later a TI package of CD's... mostly in an effort to speed up permitting and construction schedules. (Oftentimes with a contractor on board for a design / build approach). 

My question to the... Read more

I've been hearing recommendations for bipolar ionization, as a way to filter airborne virus particles in HVAC systems while avoiding the energy penalty of increased ventilation. However, I've also heard that ionizing equipment is dangerous because it produces ozone.

Does anyone have any insight into the effectiveness and/or cautions... Read more

I'm wondering if people are seeing any increase in WELL or Fitwel certification interest? Or any other 3rd party systems aimed at health and wellness? WELL seems like a higher bar and now WELL v2 offers more flexibility. Is interest and adoption of 3rd party health and wellness certs growing? 

Would anyone have an example LEED Homes v4 specification they would be willing to share?  We are working on our first LEED Homes project, a midrise low income housing development here in Houston.  We have a LEED Homes provider, but she will not provide the specifications, which seem to be quite different in requirements and submittals from our...
