About This Product

eQUEST is the most widely used energy modeling program, built on the DOE-2 simulation engine. It allows HVAC designers to create 3D building models incorporating HVAC systems, daylighting, and control strategies to calculate annual energy consumption and operating costs. Three input wizards provide varying complexity levels from schematic design through detailed analysis.
