|A NEHERS(New England Home
Energy Rater System) Rater is an individual who has passed the training,
exams, and field testing required by the NEHERS Alliance.
||All NEHERS Raters must adhere to the national HERS accreditation
guidelines promulgated by RESNET(Residential Energy Services Network).
The Federal government relies on RESNET for verification of building
energy performance for:
||Federal tax credit qualification
||EPA ENERGY STAR labeled homes
||U.S. Department of Energy Building America program
||Minimum code compliance in 16 states
|A Rater, while under the watchful eye of
both NEHERS Alliance and RESNET, is qualified to test homes for energy
efficiency levels by utilizing various tools, software and resources
issued to him/her. A Blower Door and Duct Blaster can be used to test
homes for air-leaks, air-exchange rates, air-leaks in HVAC duct systems
and more. The buildings materials, insulations, windows, mechanical
equipment, dimensions, volume, etc. are collected from the field,
or an off plan assessment of the home. The data is then entered into
a software program. The software is then able to build a model of
the home and show the utility costs, efficiencies, inefficiencies,
and areas needing improvements, amongst many more useful pieces of
information. A rating, or score, is then derived for the home. The
rating can be used to qualify for the ENERGY STAR program, utility
programs or incentives, and EIM (energy improvement loan or EEM (energy
A Rater carefully monitors the construction of a home for both efficiency
and safety. A Rater must also understand the importance of building
science and how it affects the home and its occupants.
A Rater can provide a list of suggested energy improvements –
with their estimated costs and energy savings – based on existing
conditions or proposed construction for the home, for the homeowner
or home buyer to consider.
