We recently completed our 20th home that incorporates Schellter™ Advanced Building Science technology and the results have been tremendous.
Lower HERS Scores Mean Happier Energy Bills
Our whole-house systems approach on the standard Schell Brothers home has produced an average HERS Index Score of 55. For those of you not familiar with the HERS scoring system, lower is better and each 1 point decrease corresponds to a 1% reduction in energy consumption and your energy bill.
For reference, a 10 year old plus house would likely have a score in the 125 to 150 range, a new home built to minimum code would score 100, and a new Version 3.0 Energy Star home is required to score in the 75-80 range.
So our homes on average are 45% more efficient than the code home and at least 20% more efficient than a typical Energy Star home. Keep in mind these scores are based on our standard homes – all of which include Schellter™ technology.
For those looking for extreme efficiency, we just recently completed two homes that feature the addition of Geothermal HVAC and Solar Panel options, which produced HERS scores of 30 and 32.
We Publish All our HERS Scores – Ask Other Builders if They Do the Same
In August, Schell Brothers became the first Delaware Builder to enter into an agreement with the Residential Energy Services Network (RESNET) to publish and market all HERS scores. RESNET’s Home Energy Rating System (HERS) is the Nationally recognized system for inspecting and calculating a home’s energy performance.

Each 1 point reduction of HERS index score corresponds to a 1% reduction in energy consumption. Since Energy Star requires a HERS index score in the range of 80-85 this house far exceeds those requirements.
