The first function models sensible and total heat recovery between outside air and exhaust air, with optional evaporative precooling of exhaust air before the heat recovery. The existing heat recovery of DOE-2 only allows preheating outside air when exhaust air is more than 10°F warmer than outside air. The second function models distributed energy storage for direct expansion air conditioners which cannot be modeled by any existing system type of DOE-2.1E.1 aHong, Tianzhen1 aEley, Charles, N.1 aKolderup, Erik  uhttp://www.ibpsa.org/proceedings/BS2005/BS05_0419_426.pdf
