ASSESSMENT of POTENTIAL CARBON DIOXIDE-BASED DEMAND CONTROL VENTILATION SYSTEM PERFORMANCE in SINGLE ZONE SYSTEMS
Abstract
Heating, ventilation, and air conditioning (HVAC) use accounts for 43% of commercial energy consumption, with close to 5% used for ventilation purposes. Federal government agencies face both energy consumption reduction mandates and reduced funding. Carbon dioxide (CO2) based demand control ventilation (DCV) is a technology that allows for reduced energy consumption by allowing facility designers to introduce outside air based on facility occupancy, per American Society of Heating, Refrigeration, and Air Conditioning Engineers (ASHRAE) standards. This research aims to create a generalized methodology assessing energy and cost reductions from CO2?based DCV and then apply it to a specific facility at multiple locations. This research creates a generalized methodology for future researchers to follow based on the present body of knowledge. The model application then applies this methodology to one of the Department of Energy?s (DOE) commercial benchmark facility models. The selected DOE model is a small office building with single zone HVAC air systems, assessing DCV impact on energy consumption and costs for 52 United States locations. Although the model application is not life cycle cost effective for the building modeled, it successfully identifies which areas experience the greatest cost and energy savings from DCV.
