Energy Features

For every $1 decrease in annual energy costs, the market value of a home increases by $20, according to a study published in the Appraisal Journal. If you decrease your energy costs by $300 per year, the value of your home increases by $6,000. RESNET Certified professionals can verify measurable results of the improvements performed...

h.a.Fisher Homes is RESNET Certified

Each h.a.Fisher Home is rated and certified through the RI Residential New Construction Program sponsored by National Grid. This ensures that the home performs at a certain level of energy efficiency that is above an established baseline or code level. At our option within this program, we commit to a level that is at least 25% better than the baseline. In addition to energy efficiency, the certification also helps the home to have lower operating costs, durability, comfort, and safety.

Through independent verification, the following major aspects are included in your new h.a.Fisher Home:

Quality & Performance Inspections

HERS certification (Home Energy Rating System)This system rates homes on a scale of 100 to 0, where 100 is a code built home and 0 is a zero net energy home. Typical HERS ratings for h.a.Fisher Homes’ have been between 62 and 69.

HERS certifications require modeling the home on energy software, at least two site visits during construction, compliance with construction standards, and testing at completion.

  • Attention to insulation installation quality, to ensure the insulation is doing the job it is meant to, and to avoid accidental air pockets which could cause “cold spots”.
  • Attention to air sealing to ensure that the insulation is fully aligned with the air barriers. As much heat is lost through air leakage as through wall and ceiling assemblies, so by making the house tight there can be a higher level of control. Much like the combined benefit of wearing a windbreaker over a sweater, the insulation will perform better when there is no air flow through the fibers.
  • Compliance with a 32- point Thermal Enclosure Checklist which addresses air sealing during construction.
  • Follow up to air sealing inspections is done by blower door testing to determine the tightness of the home; each home must pass this test.

Duct testing

Another major way that expensively heated and cooled air is lost is through the duct system that is “outside the shell” (in attics and basements), so the ductwork is fully sealed and then tested, each home must pass the test.


Because a home must be tight for energy efficiency, it must then also have the correct amount of ventilation to ensure good indoor air quality. Each home has a special quiet bath fan that is programmed to run a portion of the day, and is independently tested and set.
