Hello,

This is not my area of expertise but our contactor has suggested central heat pump hot water (CHPHW) is $1m more expensive than gas fired domestic hot water for a 150 unit multi-family residential building in Massachusetts. The Building Decarbonization Practice Guide is extremely helpful but, from their comments, it is all coming... Read more

Hey all,

I got plugged into this group about two weeks before GreenBuild and wasn't able to make it to the summit. I'm still catching up on all the work this group has been doing recently, but I know one of the big ticket items is the SCL Contractor Commitment.
