Research Brief: Implications of energy code evolution on energy performance of multi-­family residential buildings in the US

Abstract

The International Energy Conservation Code (IECC), which is created by the International Code Council (ICC), standardizes expectations for the design and construction of buildings with regards to energy use and conservation over the structure’s lifetime. With every new release these codes get more stringent. The goal of this analysis was to quantify how the evolution of these building codes has impacted the energy performance of buildings.
