The Home Energy Rating System (HERS) is a widely recognized standard within the residential building industry that seeks to improve the energy efficiency of residential buildings by assigning a sort of performance score called the HERS index. The HERS Index Score is a relative performance score- a home with a score of 100 is “as efficient” as a standard new home, and a home with a score of 70 is said to be 30% more efficient than a standard new home. Green building certifications such as Enterprise Green Communities often require HERS ratings to be performed to meet the standards of the certification. New Ecology provides HERS rating services for multifamily properties, ranging from projects involving fewer than 10 units to several hundred units. Often, the goals of a project dictate that certain HERS scores be met, and New Ecology has extensive experience working with project teams to ensure that projects meet their requirements- from design through completion.
