The Development of Methodology for the Determination of R Values of Existing Structures by Nonsteady State Heat Transfer Measurements.

Abstract

Energy conservation surveys of Navy facilities often require data on in-place R-values of existing structures. Such information has been difficult to obtain due to transient conditions caused by day-and-night temperature changes. This study indicates R-values can be calculated within about a 6% accuracy from heat flux and inside-outside wall surface temperature data that have been integrated over a 24-hour period. (Author)
