The award winners of the 2023 RESNET Cross Border Home Builder Challenge, which helps promote the utilization of the HERS® (Home Energy Rating System) Index have been announced by Steve Baden, Executive Director of RESNET, and Paul Lowes, President of the Canadian counterpart CRESNET. “With almost 3.7 million homes rated in the US, the HERS Index is the industry standard by which a home’s energy efficiency is now being measured in the US and Canada. It’s also the nationally recognized system for inspecting, calculating, and labeling a home’s energy performance” noted Steve Baden. “The HERS Index is based on an assessment by a certified RESNET Home Energy Rater who evaluates a home’s energy efficiency and assigns it a relative performance score. The lower the number, the more energy efficient the home. The energy efficiency score is based on variables such as exterior walls (both above and below grade), floors over unconditioned spaces, ceilings and roofs, windows and doors, vents and ductwork, HVAC systems, water heating system, and your thermostat, among other elements”, commented Steve Baden. “The RESNET Cross Border Challenge is a friendly competition between American and Canadian home builders to determine just how energy efficient builders can build,” noted Paul Lowes. This was the 10th year for the awards. There were a total of 13 builder awards presented for this year’s competition; four were based on having the lowest HERS score for their specific category, three special President’s awards based on a fleet of HERS new home ratings, and two Net Zero awards including PV Solar applications. These awards were sponsored by Power-Pipe® drain water heat recovery system, Better Builder Magazine, Beacon Building Products, BP Canada, and Panasonic. In addition, the Enbridge Innovation Award sponsored by Enbridge Gas Distribution was presented to a US and Canadian builder. This award went to the builders in the US and Canada that HERS rated a home demonstrating energy/resource innovation in new home construction. Also, there were two HERSH2O® awards for builders in the US and Canada sponsored by Greyter Water Systems. These awards went to builders in both countries with the lowest RESNET HERSH2O score. The HERSH2O score measures the builder’s demonstration of water efficiency within the home. The lower the score, the less water consumption.
