The International Code Council celebrates the 20th anniversary of the International Energy Conservation Code (IECC) this year. The IECC, which addresses the design of energy-efficient building envelopes and the installation of energy-efficient mechanical, lighting and power systems through requirements emphasizing performance, is in use across the United States, member nations of the Caribbean Community (CARICOM), Mexico, Saudi Arabia and Abu Dhabi.

To date, the energy code has saved U.S. consumers over $44 billion and avoided 36 million tons. In June, the United States Conference of Mayors unanimously adopted a resolution in support of the IECC as a cost-effective strategy to lower energy waste in the buildings sector and reduce greenhouse gas emissions.

Beyond energy savings, the IECC plays a role in promoting safer and more resilient buildings. The IECC’s building envelop provisions help control for condensation that could otherwise turn to rot. The IECC also helps maintain livable temperatures for longer in cases of extreme weather, allowing occupants to “shelter in place.”

“Energy efficiency is as important today as it was 20 years ago. Our building codes play an integral role in helping communities save money and reduce waste,” said Code Council Chief Executive Officer Dominic Sims, CBO. “The IECC helps home builders, developers, architects, engineers and others in the building industry produce the quality buildings that consumers today want, taking into account energy efficiency and the latest building science.”
