Building Energy Codes

Building codes have traditionally focused on keeping their occupants safe. Increasingly, many lawmakers are interested in ensuring that buildings use energy more efficiently as well.  Forty one states have adopted building energy codes that establish minimum requirements for energy efficiency for new or renovated buildings. Typically enforced at the state or local level, energy codes set standards for the efficiency of a building’s heating and cooling system, establish minimum insulation levels and impose other requirements to minimize air leakages. Some energy codes also set standards for the efficiency of lighting and other building features. States adopt codes to protect public health and safety, reduce building operating costs and meet pollution reduction goals.
