In their roles as the primary contributors to the LEED v4 Reference Guide for Homes Design and Construction, Abe and Carl were critical in making this document the incredibly valuable tool that it is. Their depth of knowledge of green building and the LEED for Homes program, as well as numerous images from their textbook, Green Building: Principles and Practices in Residential Construction, were instrumental to the success of this project.
