WebJul 6, 2024 · This is very easy to explain for winter heating loads. The energy analysis programs when used as peak load programs always take credit for any solar gains, people, lighting, and equipment loads to help offset winter heat losses. The specific peak load methods are more conservative and do not give credit for any offsetting loads to winter … Webwords, although the penalty in annual heating loads from reduced lighting might be minuscule in those locations, it may not be so in terms of the peak heating demand. This is particularly apparent in Los Angeles, where the heating Coincidence Factor in the large retail building jumps from 0.03 for annual load to 1.38 for peak. It may seem sur-
