Top Ten Measure 4: Bioclimatic Design
The building responds to the unique site conditions in each cardinal direction. Different strategies were utilized to control solar heat gain, improve the energy performance of the building, and introduce daylight and provide views.
The west façade, which often presents the greatest challenge to solar control, was mitigated with the integration of external motorized louvers. On a typical sunny summer day, the louvers deploy at solar noon and adjust throughout the day to prevent direct sun from penetrating the envelope. Conversely, the system welcomes solar gain and daylight to passively heat the space during the wet winter months.
At the south façade, the motorized louver system was integrated with exterior sun shades to improve daylight distribution. The louvers serve as a series of small light shelves that reflect light up onto the highly reflective, stretched-fabric ceiling. The north portion of the project reaches out to connect to an existing building that was renovated to house a modern laboratory and lunchroom, and the north-facing offices are open to Olympic Mountain views. The east façade is minimally glazed and encloses core functions.
