HOME ENERGY EVALUATIONS
TESTING & EVALUATING HOMES FOR ENERGY EFFICIENCY
A Home Energy Evaluation is intended for anyone concerned with the energy performance, durability, and comfort levels of their homes. Having an energy evaluation or energy audit performed on your home will identify where your house is losing heat, and list measures you can take to make your home more energy efficient, and save you significant amounts of money over time.
Blower Door Pressure Testing
Home Energy Evaluations uses a variety of techniques and diagnostic tools to determine the energy efficiency of a structure. We use testing equipment such as blower doors, which measure the extent of air leakage in the building envelope, and infrared cameras, which reveal hard to detect areas of air infiltration and missing insulation in the thermal envelope.
The Blower Door Test is one of the most critical factors in evaluating the energy performance of a home. Having a blower door test performed will determine the amount of air that is entering and leaving the home, and will calculate the air infiltration rate - or more commonly, how tight or loose the house is. Blower door testing will help find the many hidden openings between the heated living space and the exterior, as well as help determine the need for ventilation.
Infrared Thermal Scanning
Have you ever wondered if, or how well your home insulated? An infrared thermal scan is the only way to check without tearing out walls. The infrared camera is a heat seeking instrument that will show voids in the insulation, or reveal whether the home is insulated at all.
Older homes are notorious for being drafty, un-insulated, and full of many hidden voids, or chases, located between the heated envelope and the building exterior. These homes can cost a fortune to heat. With the uncertainty of fuel costs and supply in the near future, having an energy evaluation performed on your home will answer many questions as to the best approach to energy efficiency, and where you can get the greatest return on your home improvement dollar.
Newer, tightly built homes may be easy to heat, but can easily develop moisture problems, mold, early deterioration, and an unhealthy living environment for the occupants if the house was not built using proper building science, or, if the heating system and appliances were not installed using the "house as a system" approach. Having a blower door test performed on these homes, along with a visual inspection of existing conditions, will reveal if the house is below the "Building Tightness Limit", and identify any other sources of excessive moisture in the home.
