A new building-sealing technology developed by researchers at the University of California, Davis, will get a real-world test today at a Habitat for Humanity home in Stockton, Calif.
Developed by scientists at the UC Davis Western Cooling Efficiency Center, the green technology is designed to take the guesswork out of sealing building leaks, which account for roughly 30 percent of the energy used to heat and cool a building.
Previous testing has shown that the UC Davis aerosol sealing technology can reduce available leaks by 50 percent. With further improvements, the researchers think it has the potential to bring leakage down to nearly zero.
The technology uses a compressed nitrogen system to push a sealant through five nozzles. Once sprayed into a pressurized environment, the sealant becomes a foggy mist of aerosolized particles. These particles move toward wherever air is escaping and seal the leak... Read More
