EnergyPlus™ is a whole building energy simulation program that engineers, architects, and researchers use to model both energy consumption and water use in buildings.
When zones and enclosures are not 1:1, the zone component loads report values for "Sensible-Delayed" internal gains (People, Lights, etc.) are incorrect. They are calculated using the zone's internal gain radiant intensities instead of the enclosure intensities. These values also affect the delayed envelope components as well. This may impact results in models with air boundary surfaces and/or zones with multiple spaces in them.
