Green Multifamily Projects in the Neighborhood Stabilization Program

Posted on March 25, 2011 by Amy Hook

Recently, I was talking with another Neighborhood Stabililization Program technical advisor (NSP-TA) and he said that he heard somewhere that multifamily projects made up 30% of all NSP.

The vinyl cut-offs were baled and when a 40,000-pound load was accumulated, a plastics broker would negotiate a price for the tractor-trailer load.

Rigid Insulation Rehabs

Posted on January 31, 2011 by Peter Yost

We tend to put insulation into empty roof and wall cavities because, well, they’re empty. If a rehab gives access to the bare exterior or interior of framing assemblies, how do we decide what type of and how much rigid insulation to add, and what are the pros and cons of putting the rigid insulation on the exterior or the interior of the assemblies?
