The Terry Thomas: Seattle, WA
Old Concepts, New Tools

This Seattle commercial office building relies on passive strategies for cooling. Advanced building simulation tools allowed the building team to design the optimal environment for natural ventilation using shading, daylighting and a center courtyard. Radiant hydronic baseboards and motorized louvers controlled by CO2 sensors provide heating and ventilation in the winter. The lack of a mechanical cooling system and forced air system contribute to the building's performance of 37 kBtu/ft2 yr.
