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.
