Hi, this is a somewhat niche/specific question - we are working on an all-electric school (middle and high school) that includes a chemistry lab.

Hi everyone,

As you may know the ICC has changed the way the IECC will be written in the future and most of us think that will reduce the stringency of the future energy codes that are the biggest lever in the fight against climate change within the buildings sector.

So one of the best pathways forward is via ASHRAE, which has a... Read more

Hi All,

I will be catching up on learning units over Thanksgiving weekend and I am wondering if anyone else is experiencing the challenge of credential maintenance of their CPHD? Ideally we would have a client go for Passive House accreditation on a project, but lacking that, how are folks maintaining their 20 credits per year? For... Read more

Hi folks, I was asking around during Greenbuild and getting a variety of answers on this, and since our Contractor Commitments make a distinction between "GC's" mobile equipment as scope 1 and "Sub's" mobile equipment as scope 3. I know that many of us acting as "CM" claim full "operational control" of a jobsite and consider all fuel using on... Read more
