Home Energy Survey
This Home Energy Survey shall include on-site visual inspection of the energy features of the dwelling unit, and documentation of its general condition, including envelope features and ages; equipment types, characteristics and ages; appliance and lighting characteristics. Where available, the Home Energy Survey shall include a review of utility use and billing history. The Home Energy Survey is a visual inspection only and does not require the use of a blower door, duct leakage test, an infrared camera or other test equipment. A Home Energy Survey is not a prerequisite for the Comprehensive Home Energy Audit.
Comprehensive Energy Audit
The purpose of the Comprehensive Home Energy Audit is to cause improvement to be made to the audited home. The Comprehensive Audit includes an evaluation, performance testing and proposed treatments for improvement of an existing home. The evaluation shall include a review of the data collected from any previous energy audit or Home Energy Survey, any further required measurement and performance testing, combustion appliance testing, and a computerized simulation analysis of the home's energy performance and a calculation of the energy and environmental savings from improving the energy performance of the home. The performance analysis shall determine the scope of work for the home. The qualified Auditor shall guide the homeowner to a Certified Contractor. A homeowner may elect to go through this process without a requirement of a prior Home Energy Survey.
Blower Door: A blower door is a powerful fan that mounts into the frame of an exterior door. The fan pulls air out of the house, lowering the air pressure inside. The higher outside air pressure then flows in through all unsealed cracks and openings. The auditors may use a smoke pencil to detect air leaks. These tests determine the air infiltration rate of a building.
Duct Testing: Similar to blower door testing, duct blowers are used to determine the amount of air leakage through a building’s duct system. Duct blowers results indicate the inefficient distribution of conditioned air within a building, leading to wasted energy and pressure differences within the building that can cause indoor air quality issues.
