Lawrence Berkeley National Laboratory: Integrated, High Performance Facade Solutions

Introducing the appropriate tools, tests and methods early in the design process can lead to more successful building facades.  The speaker, Eleanor Lee emphasized the importance of balancing HVAC loads, artificial lighting and day lighting to achieve optimal performance. She introduced several freely-available analysis tools that can be used at different scales of facade analysis to alert designers to potential human comfort issues (glare, solar heat gain, etc.)  Among these where COMFEN, a front end for Energy Plus;  BCVTB, a middleware used to integrate Energy Plus and Radiance; and DAYSIM, a Radiance based analysis program. More detailed descriptions of these tools can be found in the analysis tools blog entry here.

Eleanor also described research and testing performed through a partnership between LBNL and the New York Times on the Renzo Piano designed headquarters building in New York. LBNL performed extensive computational analysis and built a full scale mock-up in order to advise the client on the selection of appropriate automated interior sun-shading systems and optimal calibration.
