BUILDING SCIENCE FORMS THE FOUNDATION
EFL Certified Green grew from guidelines originally written by two influential building scientists, John Tooley of the Advanced Energy Corporation and Joseph Lstiburek of Building Science Corporation.
The original EFL program introduced in 2001 sets a number of performance standards for buildings for “gold” and “platinum” status. Unlike LEED for Homes or NGBS, there is no scavenging for points. A building either meets the standards or it doesn’t.
Builders don’t have to use Masco building products to participate, although a companion rating system called “Ecomagination” is essentially a marketing tool for GE products.
