What a HERS Score of 56-60 Means for a Shoreline Home

Shoreline1 min read

Shoreline's Phase III plans carry third-party HERS Index scores of 56 to 60. Learn how the scores compare energy use and why they do not predict a utility bill.

Shoreline's Phase III plans carry third-party HERS Index scores of 56 for Peak, 59 for Skyline and 60 for Vista. The scores help buyers compare a home's modeled energy use with a standard reference home.

HERS stands for Home Energy Rating System. Its reference home scores 100 and represents a comparable home built to 2006 energy standards. A net-zero home scores 0. Lower scores mean less modeled energy use.

Each point below 100 is roughly one percent less modeled energy use. A score of 60 models about 40% less energy use than the reference home. HERS does not predict your utility bill, which depends on your home, weather, rates and how you live. A rating belongs to a specific home, so ask for the completed certificate for the home you are considering.

Several features contribute to Phase III's energy performance. The homes have R-23 insulation in 2x6 exterior walls, with foam sealing at rim joists and truss ends to limit air leaks. Low-e double-paned Marvin® windows limit heat transfer. A 95%-efficiency natural gas furnace and sealed ductwork within conditioned space help heat the home efficiently. Programmable thermostats let you adjust heating and cooling to your schedule.

In Utah's cold winters and warm summers, insulation and air sealing also help keep indoor temperatures consistent and reduce drafts.

Phase III homes are ENERGY STAR® certified, with an independent third-party rater verifying that they meet the EPA's energy efficiency guidelines. Phase IV ratings will be confirmed per home. See the plan-by-plan scores and construction details on our Phase III energy performance page.
