IECC Energy Conservation Code Book
The 2021 International Energy Conservation Code is a comprehensive reference for professionals working with the energy-efficient design, construction, alteration, and evaluation of buildings. Published by the International Code Council, it establishes minimum energy-conservation requirements through both prescriptive and performance-based compliance options.
The book contains separate provisions for commercial and residential buildings. Its requirements address climate zones, exterior building envelopes, insulation, fenestration, air leakage, heating and cooling systems, ventilation, service water heating, electrical power, lighting, and other building systems that influence energy use. It also includes provisions for additions, alterations, repairs, changes of occupancy, and certain existing buildings.
The commercial provisions generally apply to nonresidential buildings and residential buildings more than three stories high. The residential provisions address detached one- and two-family dwellings, multiple single-family dwellings, and qualifying Group R buildings three stories or less above grade. This two-part structure helps users locate requirements according to the building type being designed or reviewed.
Architects, energy consultants, engineers, contractors, building inspectors, plans examiners, code officials, facility managers, instructors, and students can use this edition during design development, energy calculations, permit preparation, plan review, construction, inspection, and professional study.
The code also includes appendices addressing solar-ready zones and net-zero-energy provisions. Appendices become enforceable only when adopted by the relevant jurisdiction. Its coordinated structure makes the book valuable for both day-to-day technical reference and examination preparation where the 2021 IECC is specified.
Energy-code adoption and local amendments vary. Buyers should confirm the edition required for their jurisdiction, project, employer, course, or examination.
Order one copy for professional or educational use, or request bulk pricing for design firms, contractors, building departments, colleges, training centers, libraries, and resellers.
