| Abstract | A consortium research project was initiated to determine the field performance of various thermal insulation products as applied in the exterior insulation basement system (EIBS). Initially a two-dimensional analytical tool was used to derive the thermal transmission characteristics from an array of temperature measurements monitored over a period of two years. Results immediately showed the influence of lateral heat flux between various products that differed in thermal transmission properties. Therefore, development of a three dimensional model became imperative, to resolve the order of magnitude of the lateral heat flux in the experimental set-up, and determine the actual in-situ properties of the insulation specimens. This report gives the theoretical and numerical approaches adopted to develop a three-dimensional computer model of heat transfer. The implicit Spline Method was selected for the problem solver. The applicability of the model was verified using measured data on temperature distributions at several material interfaces. Then the model was used to estimate the effect of lateral heat flows, and to determine the in-situ thermal properties of the insulation specimens. The report also records experimental details and presents validation results of the analytical approach. |
