Saving with Automated Systems

While static window technologies provide practical low-cost technological options to manage both space conditioning and lighting energy use, automated fenestration systems offer the potential for greater, more optimized total energy savings in response to variable conditions. The dynamic range of outdoor illuminance and irradiance is orders of magnitude greater than the desired indoor range—static façade systems simply cannot always provide the optimal envelope response to the immediate environmental conditions.

With this in mind, the future design of high-performance buildings is expected to involve active façade technologies, acting in intelligent collaboration with HVAC and lighting systems to produce comfortable indoor environments with reduced energy consumption. In collaboration with industry, LBNL researchers are working to develop, test, and increase market adoption of innovative, intelligent dynamic façade systems.
