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 CO2based 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 Energys 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.
