Scientists to speak about cool roof study in Fresno

Scientists from the Lawrence Berkeley National Laboratory are studying the use of sealed attics, or cool roofs, in two Fresno homes.

The idea is that sealing the attic, by moving insulation from the floor to the underside of the roof deck, will allow HVAC equipment and ductwork to operate within a home’s living spaces to reduce heat loss in winter and prevent heat gains in summer.

The lab’s field work and building simulations show that the energy savings could amount to 10 percent or more in a newly built home and 30 percent or more in a retrofitted home.

The scientists will discuss their local research project on “Heat Island Effect and Energy Efficiency” during an event Feb. 19 hosted by the U.S. Green Building Council Central California. The program will be held 9 to 11 a.m. at the University Business Center at Fresno State. The event is free for building council members, $15 for non-members and $5 for students.

The speakers include Ronnen Levinson, staff scientist and leader of the Heat Island Group, at the national laboratory and Jonathan Slack, senior scientific engineering associate.

The laboratory is leading California’s efforts to save energy, lower urban air temperatures and to reduce greenhouse gas emissions through cool community strategies like cool roofs, cool pavements, cool walls and urban vegetation.
