Building Performance
Testing
Re:Vision’s team of building performance specialists conduct diagnostic and performance testing to identify potential building issues and/or verify quality of construction. Tests include:
Thermography — Thermographic imaging uses infrared radiation to detect differences in surface temperatures. These images can help identify air leaks, water infiltration, and thermal deficiencies, like missing insulation or thermal bridges.
Blower Door Testing — Blower door testing uses a large fan to pressurize or depressurize a building. Under this pressure, air leaks can be identified and quantified. Air leakage can lead to issues such as low occupant comfort, high utility bills, and moisture problems.
Duct Leakage Testing –- Using a smaller version of the blower door fan, ducts are tested to quantify leakage and identify locations. Duct air leakage leads to increased energy use, and may cause other problems such as mold growth or dampness.
HERS Rating — A HERS rating uses blower door testing and a detailed inspection to build an energy model that estimates the overall efficiency and energy use of a home. Improvements to the home can also be simulated to estimate energy savings and payback periods. HERS ratings are required for programs ranging from PHIUS to energy efficient mortgages.
Indoor Air Quality Testing — IAQ Testing is a diagnostic tool for spaces with air quality concerns, and it can also verify post-construction air quality prior to occupancy. Re:Vision uses protocols that are consistent with ASTM, EPA Compendium, or ISO methods, as applicable.
