Residential Compliance Using REScheck-Web

REScheck is a web-based platform that doesn’t require any software installation on your personal computer. The REScheck building energy code compliance software makes it fast and easy for builders, designers, and contractors to document and calculate whether new homes, additions, and alterations meet the requirements of the IECC as well as a number of state energy codes. REScheck also simplifies compliance determinations for building officials, plan reviewers, and inspectors by allowing them to quickly evaluate whether low-rise residential buildings and dwellings meet the code. REScheck is widely accepted and used by the majority of states and municipalities across the U.S. as a leading means of successfully and easily demonstrating compliance with building energy codes.

The 2021 International Energy Conservation Code

The new installment of REScheck adds support for the residential provisions of the 2021 IECC, the latest model energy code for residential buildings. The 2021 IECC was released by the International Code Council (ICC) and affirmed by the Secretary of Energy earlier this year (under 42 USC 6833), and provides 9.4% energy savings in residential buildings compared to the previous 2018 edition. Adopting and implementing the latest building energy codes represents a significant opportunity to save energy, reduce waste, and help ensure that American homes and businesses are safe, healthy and resilient. Through 2040, modern energy codes are expected to result in over $138 billion in energy cost savings, and over 900 MMT of avoided CO2 emissions—equivalent to the annual energy consumption of over 195 million passenger vehicles or 108 million homes.
