Green Building Program Verification

Four Walls, Inc. is committed to advancing energy efficiency in the commercial and residential sectors through green building programs and energy code. Energy efficient buildings offer long-term value. They are more comfortable places to live and work, are more affordable to operate and maintain, and produce less greenhouse gas emissions than conventional buildings.

Programs such as ENERGY STAR® and Energy Trust EPS™ provide builders, engineers, buyers and renters with the assurance that a building has been verified for quality and energy performance. In order to leverage labels such as ENERGY STAR® for marketing purposes, a homebuilder must have their buildings tested and verified by a third-party energy consultant such as Four Walls, Inc. During this process, we make recommendations for energy improvements and check that mechanical systems and energy-efficiency features are installed correctly.

Four Walls, Inc. provides third-party testing and verification for green building programs, including:

  • ENERGY STAR® for Homes
  • Energy Trust Energy Performance Score™
  • Home Energy Rating System (HERS)
