2021 International Energy Conservation Code (IECC), paperback

The 2021 International Energy Conservation Code sets energy efficiency requirements for residential and commercial buildings. It looks at energy efficiency from several angles: cost, energy use, use of natural resources, and the effect of energy use on the environment.

Energy raters, architects, mechanical and electrical engineers, builders and code officials use the IECC to check insulation, fenestration, air leakage, HVAC and lighting requirements. This listing is the 2021 edition, ISBN 9781609839611.

How the IECC is organized

The IECC has separate commercial and residential provisions. Each part gives a prescriptive path and a performance path, so designers can follow set values or show compliance through energy modeling.

Who should buy the 2021 IECC

Home builders and HVAC contractors in jurisdictions on the 2021 energy code, energy auditors, plans examiners, and students studying for energy code exams that list the 2021 edition.
