Evaluation of Energy Conservation Measures by Model Simulation

Numerous energy conservation measures are being implemented into the air handler units of today's commercial buildings. The economizer cycle has proven potential, and has become increasingly more common. Work has also been done demonstrating that hot and cold deck reset schedules, optimized according to outside air temperature, can result in significant energy savings. This paper presents a case study of these energy conservation control schemes in a dual duct VAV building on the Texas A&M campus in College Station, the Harrington Education Tower. The current system was simulated and the model used to investigate the effects of economizer cycles and optimization of the hot and cold deck reset schedules
