EMPS 2 - A computer program for residential building energy analysis.

Describes a computer program developed for the analysis of residential building thermal loads and space heating and cooling energy use. It is capable of modelling the simultaneous heat balances on multiple spaces, building air flows by infiltration and natural and forced ventilation, including thermostatically controlled through the house ventilation, detailed solar gain, part load performance of central and unitary heating and cooling systems, and thermostat droop and cycling characteristics. The air exchange algorithms attempt to account for the interactions of the pressure terms associated with the various modes of air movement on the net building air change rate. Arbitrary combinations of central and unitary heating and cooling systems can be assigned to the various building spaces.
