DOE-2

DOE-2 is an energy simulation program intended to aid in the analysis of energy usage in buildings. Using DOE-2, AEC analyzes design alternatives that improve energy efficiency while maintaining thermal comfort and cost-effectiveness of buildings. By providing simple or increasingly detailed description of a building design or alternative design options, accurate estimates of the proposed building's energy consumption, interior environmental conditions and energy operation cost can be obtained. DOE-2 can be used in many applications, especially those involving design of the building envelope and HVAC systems, and selection of energy conserving or peak demand reduction alternatives.

AEC has experience modeling and analyzing a wide range of energy efficiency measures, including the following:

High efficiency chilled water plants, including chillers, pumps, cooling towers and controls.
Air distribution systems, including outside air economizers, variable speed fan controls, energy efficient motors, terminal boxes, temperature and pressure reset controls, and duct improvements.
Lighting efficiency improvements through more efficient fixtures, occupancy sensors, time of day controls, daylighting controls or through design changes.
Energy management systems covering HVAC and lighting.
Envelope improvements such as high albedo (reflectance) roof surfaces, insulation and high performance windows.
Heat recovery for water heating.
High efficiency boilers and water heaters.
Cooling efficiency improvements through high efficiency packaged systems, evaporative cooling, and multiple compressor systems.

In addition to DOE-2, AEC has created or uses a variety of DOE-2 related computer software tools including VisualDOE 4.0 and eQuest.
