Effective U values are a measure of average building component thermal performance. This report presents tables of effectivee U values for twenty opaque wall sections, single, double, and triple glazing, and eight types of passive solar walls. These values represent an improvement over the original calculations due to an updated, experimentally verified computer code, a better climatological classification scheme, more region-specific weather data sets, and analysis performed over the entire heating season. The results emphasize the fact that building envelope components are passive solar heating devices whose performance is sensitive to thermal mass storage capability and absorbed solar radiation.
