Welcome to eco-rated, an energy and environmental efficient certification program designed for engineered factory built homes. Developed by the Northwest Energy Efficient Manufactured Home Program’s team of building scientists, energy experts and industry partners, an eco-rated engineered green home is your certified green home solution.

An eco-rated engineered green home must meet or exceed requirements from the entire process of construction. A builder must be certified to build, homes must be inspected during construction, and can only be sold by certified retailers and contractors.
