Keep Buildings Airtight

Picture this: you have your house insulated but are still too cold in the winter, too hot in the summer, and your energy bills are racking up.

Sound familiar? This problem is usually caused by small, open areas in a building exterior where warm or cool air from the inside escapes or exterior air sneaks in. Using the air conditioner or heater to compensate for it being too hot or cold due to the gaps can drive up energy bills.

The California Energy Commission awarded a grant to the Western Cooling Efficiency Center at UC Davis to research methods and technologies to save energy. As a result, the center developed an aerosolized sealant spray that detects and seals areas where air leaks, which could help reduce up to 30 percent of the energy needed to heat and cool a home or office.

The potential for this product is dramatic. If all commercial and residential buildings used aerosolized sealing, monthly savings could exceed $1.5 billion per year. In addition, the sealant spray can lower construction costs. Instead of taking eight hours, contractors can seal a 1,200 square foot home in half that time.
