A methodology for assessing the potential for a CO2 retrofit on an existing building is presented in this paper. A case study is described, the subject building is an Energy Star rated building that has a Direct Digital Control (DDC) system. The complexity of a CO2 ventilation control retrofit is related to the type of building control system currently in place. Significant energy savings are possible through the application of a well-conceived executed ventilation control strategy.
