Hello all, 

Wondering if anyone has experience with lead limits in electrical cable and wiring? 

LEED for Healthcare allows a limit of 300 ppm of lead in electrical wire and cabling - my search for compliant products has been all dead ends. (MRc PBT Source Reduction - lead, cadmium, and copper)

Peter Yost (at https://building-wright.com/ )  is available to provide building science expertise, trainings, public speaking, building investigations, and more. Learn more

My dear collegues,

As I'm sure is true for many of us, the events of the past weeks (months/years/decades...) have emphatically reinforced to me the need for a radical shift in how we meaningfully address JEDI in what we do. One (admittedly small) step I've been thinking about are the statements of reconciliation that have become more... 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...

Hi all, how many of your companies have started ESG reporting? If so, are you working with a consultant to calculate your impact of business operations? Or are you calculating it yourself? Are you purchasing offsets? I've been getting a lot of cold calls about this, mainly from a UK-based company. We are not yet at this point, but it seems like... Read more

All,

We are collecting examples of buildings that involved electrification initiatives (building does not need to be all electric as long as largely electric). Please share your projects with us through this short survey. It will take 8-10min to complete.

The study will culminate into a report and best practices to advocate for... Read more

Hey there SDLs!

We're having a debate in our firm about whether we're at a tipping point to hire an in-house energy modeler - someone capable of doing an MEP-caliber energy model inside a design firm. I know some you have in-house energy modelers on staff and I'd love to hear your experiences:

- How did you know your firm was at a... Read more
