How long is ENERGY STAR certification valid on a building?

When a building receives EPA’s ENERGY STAR, the certification decal contains the year in which the certification was received. Similarly, buildings included on the ENERGY STAR registry of certified buildings and plants are listed with the year they received the award.

Certification decals may be displayed indefinitely on qualified buildings. However, recipients of the ENERGY STAR are encouraged to continue benchmarking their buildings’ energy performance and re-apply annually to keep their certification current.
