PV Project Thermography - Comparison (5/7/98)

West-facing Window in Late Afternoon

These IR photographs of the west-facing window in the master bedroom, taken between 2:30PM and 3:30PM, show the superior building envelope performance of the PVRES house. Since two photographs were taken with the same temperature scale, it can be said that the temperature of the PVRES window is approximately the same as the control house wall. Not only is the wall and window of the PVRES house noticeably cooler, but the floor is as well. The large overhang of the PVRES house prevents the sun from directly beating down on the interior floor of the bedroom, as is seen in the control photograph.

The temperature range is from 66°F (darkest colors) to 84°F (lightest colors).
