DOE-2

Simulation of Energy Consumption of Buildings

DOE-2 is a detailed multi-zone hourly simulation program widely used in the United States and abroad for calculating the energy consumption of buildings. DOE-2 can model the impact of hourly variations in ambient climate conditions and internal loads on the building load, as well as varying equipment performance characteristics and realistic operating conditions such as thermostat setbacks and window venting.

DOE-2 contains two programs: LOADS and SYSTEMS. The LOADS program calculates the hourly heating and cooling loads of a building or thermal zone at a set indoor temperature. The SYSTEMS program contains algorithms for simulating the performance of the heating, ventilating, and air conditioning (HVAC) equipment used to control the temperature and humidity of the building or zone. SYSTEMS combines the loads output from the LOADS program with the building description inputs to find the capacity, air-flow rate, efficiency, part load characteristics, and thermostat settings of the system, as well as the temperature and schedule for window venting. It also solves for the indoor air temperature, the true hourly load on the system and its energy consumption.
