Hi SAL friends,

As some of you have heard by now, we've decided to shut down this Peer Network.

After several years of trying, we have not managed to activate it as we had hoped. Given the urgency of the collective action we need to transform the building industry into a force for good in the world, we all need to focus our... Read more

Folks, it is with a heavy heart that I write this: Lance Hosey passed away unexpectedly on Friday. 

Many of you know him from the early days of the SDL group, or as an outsized presence at any of the many conferences where we overlap. He's been a list-maker, poll-taker and all around troublemaker in my life for over 20 years; I know I am... Read more

Hi friends,

We recently tracked our water consumption on site during the structural demolition of some existing reinforced concrete buildings.  The new OSHA silica regulations required us to keep dust to virtually zero, so we had a bunch of mist cannons and water hoses pumping water around the clock.  We consumed ~855,000 gallons in a...

Love the profile of Anica as the "featured member" on AIA's website--congratulations, Anica!

It's great to see the "just do it" attitude to achieving the 2030 goals: "We do not rely on clients to tell us to design a high-performance building; we are going to do it anyway, it's our job."

Hello!

I'm curious what other firms like to use to run site-specific sun path and wind path analysises that is relatively intuitive to use and generates good graphics. We have used the climate consultant software for wind roses which is free and simple. We've also used sefaira but we're hoping to crowd source more resources. We purchased... Read more

Has anyone here found an alternative to XPS for the void former?

A structural engineering contact was included in recent conversations about embodied carbon in insulation materials and brought to our attention that this is a common use for XPS that has nothing to do with its insulating properties. It is typically used where concrete is... Read more

When I upload a profile picture, it appears on the standard profile page from "My Account" but when I navigate to the BIT Best Practice 01, the image does not show and it takes me to another profile page that does... Read more

Untreated rainwater leaving a developed site is effectively a chemical spill, laden with pollutants that include oil, sediment, heavy metals, nitrogen, and phosphorous. The heat carried by stormwater is also harmful to fish and other aquatic organisms.

BuildingGreen-Approved Systems

We approve systems that:

I was recently asked about potentially specifying concrete with wood nanoparticles and concrete with biochar as a way to further lower the embodied carbon and to increase concrete strength.  These approaches are something I know nothing about, and wondering if anyone in this group has any experience and/or observations that might be relevant to...

Are any of you working on projects that are pursuing the additional point for Indoor Water Use Reduction on a HC project via Table 4 Compliant laboratory and medical equipment? If so, what sterilizers are the projects using?

We are receiving pushback that the Sterilizer metric doesn't make sense. I am interested in any insight or a... Read more
