Energy Efficiency Requirements for Public Buildings

Jocelyn Durkay 11/20/2013


An increasing number of states are adopting energy efficiency mandates for public buildings through legislation or executive order. Forty seven states have energy efficiency requirements for state-owned or funded public buildings that go beyond the state energy code. Efforts are varied and include specific savings targets and requirements to meet efficiency standards, such as the U.S. Green Building Council’s Leadership in Energy & Environmental Design (LEED) Silver, for new or renovated facilities. Other common standards include those established by the American Society of Heating, Refrigerating and Air‑Conditioning Engineers (ASHRAE), as well as  Green Globes and the U.S. Environmental Protection Agency’s ENERGY STAR. The LEED Silver certification, required in 16 states, is the most common mandate for public buildings. However, half of those states allow the two-globe equivalent of Green Globes in lieu of LEED Silver certification. A majority of states have a requirement for state buildings to achieve any level of LEED or Green Globes standards, ENERGY STAR standards or the ASHRAE 90.1 or IECC model building energy codes. Requirements generally apply to new construction and significant renovations. States may differentiate between state-owned facilities and state-funded facilities.

The map below displays states with energy efficiency mandates for state buildings. At least four states—Delaware, Massachusetts, Nevada and Virginia—have mandates only for executive branch state buildings. Alaska has no energy efficiency mandate for state buildings, although the state has requirements for certain public and publically-funded buildings. Pennsylvania and Vermont have energy efficiency mandates for state buildings without specific standards or targets.
