Comparison of Annual Heating Loads for Various Basement Wall Insulation Strategies by Using Transient and Steady-State Models

Source

A one-dimensional steady-state model and a two-dimensional transient model were used to calculate the annual basement wall heating loads for severe (Minneapolis, Minn.) and moderate (Columbus, Ohio) climates. Interior and exterior basement wall insulation strategies with both full and partial wall coverage were examined. Thermal resistance values ranged from RSI 0 to 3.5 (0 to 20 h·ft2·°F/Btu) for the insulation.

For these insulation configurations, the steady-state approximation agreed with the more detailed finite difference program to within 5 to 12 percent of the annual uninsulated wall heating load. Interior insulation exhibited a marginal improvement over exterior placement for full wall applications. Thermal bridging effects more seriously degraded the performance of interior insulation, however, when partial wall coverage was employed.
