Quantifying the effects of rooftop modifications on building thermal environment through field measurements

Anthony Dominguez, University of California, San Diego, La Jolla, CA; and J. Kleissl

The DEMROES project (Decision Making using Real-Time Observatories for Environmental Sustainability) is an environmental observatory consisting of a wireless network of real time meteorological stations. The network is installed across the University of California, San Diego campus, reaching from the Pacific Ocean to 2 miles inland. This allows representative studies of meteorological gradients specific to the urban-coastal environment. The data gathered from this observatory advances environmental sustainability by reducing building energy consumption, optimizing irrigation water use, and conducting solar power resource mapping.

Building material thermal properties such as albedo, conductivity, and heat capacity have a strong effect on their rooftop surface temperature. DEMROES data of rooftop temperatures in conjunction with thermal imaging data was used to quantify the effects of rooftop modifications such as solar photovoltaic panel installation and reflective roof coating on the building thermal environment.
