Describes a small calibrated hotbox, developed at Lawrence Berkeley Laboratory for studying methods of improving window performance. Describes the construction and calibration of the box. Discusses measurements of thermal conductance made with the box. Finds the hotbox is reliable with known skin losses and free of systematic errors to at least the 7% level.
