What is an Energy audit?
An energy audit is an assessment of your home's physical structure, fuel usage, utility costs, and lifestyle considerations to determine the level energy consumption. The audit is designed to help identify areas of energy loss and find practical, affordable ways to improve energy efficiency, lower your utility and fuel bills, and make your home or business more comfortable
What are the benefits of an energy audit?
A energy auditwill identify areas of energy loss, Reduce your utility bills, Reduce fuel consumption Increase the comfort of your home and business, helps you avoid unnecessary and costly home repairs, enhances your home's resale value, provides a healthier environment, improves the environment.
What is an infrared scan?
A thermographic inspection is either an interior or exterior survey. The energy auditor decides which method would give the best results under certain weather conditions. Interior scans are more common, because warm air escaping from a building does not always move through the walls in a straight line. Heat loss detected in one area of the outside wall might originate at some other location on the inside of the wall. Also, it is harder to detect temperature differences on the outside surface of the building during windy weather. Because of this difficulty, interior surveys are generally more accurate because they benefit from reduced air movement.
How does infrared scanning work?
Thermography measures surface temperatures by using infrared video and still cameras. These tools see light that is in the heat spectrum. Images on the video or film record the temperature variations of the building's skin, ranging from white for warm regions to black for cooler areas. The resulting images help the auditor determine whether insulation is needed. They also serve as a quality control tool, to ensure that insulation has been installed correctly.
What is a Duct test?
A Duct Blower or Duct Blaster is a device that is similar to a blower door and is an accurate tool for measuring the tightness of the ducts. The duct blaster is used to pressurize the duct system when all the registers are blocked. Measuring the air flowing through the duct blower's fan housing gives an accurate measurement of duct leakage. By pressurizing the house and the ducts at the same time, we can measure the amount of conditioned air that is leaking outdoors. This test provides measurements of duct leakage in cubic feet per minute (cfm).
What is a blower door test?
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. There are several reasons for establishing proper building tightness are to reduce energy consumption due to air leakage, to avoid moisture condensation problems, to avoid uncomfortable drafts caused by infiltration, to analyze the risk of poor indoor air quality and contamination by pollution.
