The Design and Fabrication of a Calibrated Hot Box Apparatus


A second generation research calibrated hot box was designed and constructed at the University of Massachusetts's Building Energy Research Laboratory. The hot box was built to meet the test methodologies specified in the American Society for Testing and Materials (ASTM) Standard Test Methods C 976 [1] for calibrated hot boxes and C 1199 [2] for fenestration system hot box test methods.

The hot box has the capability of simulating both parallel and perpendicular weather side wind directions on building assemblies, including fenestration (window and door) systems. The weather side chamber has a temperature range of -23.3 °C to 60 °C (-10 °F to 140 °F) and the room side chamber has a temperature range of 21.1 °C to 60 °C (70 °F to 140 °F). The design, fabrication, and instrumentation are described in detail.
