This document is 'Chapter 4.3: Building Codes for Energy Efficiency' of the Energy and Environment Guide to Action. Building energy codes require new construction and major renovations in existing buildings to meet minimum energy efficiency requirements. Well-designed and enforced codes can institute construction practices that reduce building life-cycle costs and occupants' total housing or commercial costs. Building energy code requirements can also help reduce peak energy demand, as well as greenhouse gas (GHG) emissions and other air pollutants. Recognizing these benefits, a majority of states have adopted building energy codes for residential and commercial buildings.

This chapter provides recommendations on establishing, implementing, and evaluating state building energy codes. State success stories are included for reference.
