In honor of Daylight Hour 2020, we welcome one of the foremost building science engineers in the US to Radio BE-Ex, Steve Selkowitz.  As the long time Group Leader of the Windows and Envelope Materials Group at Lawrence Berkeley National Lab Steve has driven the advancement of high performance building envelopes for decades and was a primary force behind the creation of FLEXLAB–the Facility for Low Energy Experiments in Buildings–a test bed facility that allows for the testing of energy efficiency technologies in a highly instrumented but real world environment.  BE-Ex was honored to partner with Steve and his team at LBNL on one of our early projects, the Living Lab: Advanced Daylighting Controls Demonstration Project, in 2014.  The recipient of numerous awards and accolades, Steve will join us to talk about his long focus on daylighting in buildings, the advancements he’s seen over that time and what we can expect in the near future.
