A qualitative analysis is conducted, identifying all changes made to the previous edition of the IECC, and characterizing these changes in terms of their anticipated impact on residential building energy consumption. more » To meet these statutory requirements, as well as to assist states and adopting entities in understanding associated savings, the DOE Building Energy Codes Program and Pacific Northwest National Laboratory (PNNL) conduct analyses to evaluate the differences between the latest edition of the IECC and its immediate predecessor.

The latest edition of the IECC, the 2015 IECC, was published on Jand forms the basis of this analysis.
Iecc 2018 compared to ashrae 90.1 2016 code#
The International Energy Conservation Code (IECC), as administered by the International Code Council (ICC), establishes the national model code for energy efficiency requirements for residential buildings. Section 304(a) of the Energy Conservation and Production Act, as amended, requires the Secretary of Energy to make a determination each time a revised edition of the 1992 Model Energy Code (MEC), or any successor thereof, is published with respect to whether the revised code would improve energy efficiency in residential buildings. This report provides an assessment as to whether new buildings constructed to the commercial energy efficiency provisions of the 2018 IECC would save energy and energy costs as compared to the 2015 IECC. more » While Standard 90.1 is the national model energy standard for commercial buildings (), many states have historically adopted the International Energy Conservation Code (IECC) for both residential and commercial buildings. In support of DOE’s determination, Pacific Northwest National Laboratory (PNNL) conducted an energy savings analysis for Standard 90.1-2016 (DOE 2017). As required by federal statute (), DOE recently issued a determination that ANSI/ASHRAE/IES Standard 90.1-2016 would achieve greater energy efficiency in buildings compared to the 2013 edition of the standard. Department of Energy (DOE) Building Energy Codes Program supports the development and implementation of building energy codes and standards, which set minimum requirements for energy-efficient design and construction for new and renovated buildings, and impact energy use and greenhouse gas emissions for the life of buildings.
