Title 24 Compliance

Title 24 of the California Energy Commission (CEC) outlines energy efficiency standards for new, altered, and existing buildings in the state of California. California requires a minimum mandatory energy score, as well as mandatory compliance measures. Optional upgrades and tests can translate into compliance points. For more information, visit the CEC website.



HERS Raters

The Home Energy Rating System (HERS) is used to test and enforce energy code standards set by the California Energy Commission. HERS Raters are private building inspectors who perform state compliance inspections and functional tests on residential and commercial buildings. Compliance testing has been legally required since 1974, and the codes are updated every couple of years. A HERS Rater is licensed by the Environmental Protection Agency (EPA) as an HVACR (Heating, Ventilation, Air conditioning, Cooling, Refrigeration) technician. At BarrierEnergy, our certified HERS Raters are thoroughly trained on all new building codes and regulations.

Building Air Leakage Test Definition

Building leakage refers to how tightly a building is sealed as a whole. A building’s envelope is the exterior construction of a building. Air could be leaking into or out of a building from windows, doors, flooring, roofing, and so on. A duct blower is fitted to a doorway, while the exterior door and windows of the building are sealed. Inside doors must be open during the test. The blower pushes air into the house and pulls air out to gauge how much energy it requires to pressurize/depressurize the building. Then, those readings are used to determine the total average air leakage.

Why Air Leakage Finders are Important

1) Air Quality: Knowing your home or business is properly sealed will give you peace of mind. Improving your indoor air quality can also improve your health and safety.

2) Save Money and Resources: Efficiency saves energy and resources. Think of how much air could be escaping your home through gaps that could be easily sealed. That is air you paid for; literally money out of the door! Thusly, you will see the benefit in your wallet. In fact, the EPA recognizes an average of 10-15% savings in properly sealed buildings.

3) Creature Comfort: Have you ever walked into a room and noticed it was very drafty or muggy? Problems with building air leakage can cause an uneven distribution of temperature. Furthermore, it’s more difficult for your HVAC system to heat or cool your home entirely. Don’t be stuck with poor temperature control during peak seasons.

4) Increase Value: The market for efficient real estate is steadily rising. Buyers want the security of knowing they are signing up for low bills and longstanding performance. Even HVAC systems last longer in efficient buildings, which are costly to replace. Consumers are getting wise to these facts and will pay for a building stamped with the seal of energy efficiency.



If the testing results do not meet efficiency standards, identified leakage paths must be be sealed properly. Solutions are fairly simple and cost effective. First, our air leakage finders must locate the problem spot(s). A visual inspection or a smoke test will uncover the leak. Lastly, the technicians will offer diagnostic solutions such as insulation, caulk, window replacement, etc.
