Vital Signs Case Study: The Watzek House

Thermal Comfort

Crawlspaces, Glazing, and Cross Ventilation:
Design Intentions for a Northwest Regional Style House

Christina Bollo + Robin Elder + Greg Thomson

The essential purpose of our case study was to analyze and evaluate the various components of thermal comfort as they exist in this unique historic home. We established hypotheses about the influences of different parts of the building envelope and interior on thermal comfort, and recorded data which helped us to reach conclusions about our hypotheses.

Our case study concentrated on the impacts of unexcavated crawlspaces, and glazing systems on the temperatures of three different rooms in the Watzek House. Our studies of the dining room, library, and living room were based on the similarities in characteristics in those rooms which would allow us to make definitive conclusions about what influenced thermal comfort the most.

Most importantly we had the great fortune to experience one of the region's most important and impressive buildings, while at the same time gaining insight into the function and life of an historic home.
