McKenney's, Inc. Recommends Demand Control Ventilation (DCV) to Improve HVAC Energy Efficiency

Atlanta, GA (I-Newswire) February 18, 2014 - Columbia Property Trust is one of the nation's largest office real estate investment trusts (REITs) committed to sustainable practices that maximize energy efficiency and reduce environmental impact on the community. They have become an industry leader in sustainability in many ways, including being named a 2013 ENERGY STAR® Partner of the Year by the U.S. Environmental Protection Agency.

With aspirations of achieving even greater energy efficiency, they approached the McKenney's Automation & Control Solutions (ACS) team for insight and recommendations to improve its HVAC system efficiency. McKenney's recommended an innovative approach to monitor and adjust the building's outside air ventilation levels based on ASHRAE® 90.1 standards. The solution involved introducing Demand Control Ventilation (DCV) to monitor the amount of outside air entering the building based on carbon dioxide (CO2) concentrations. CO2 levels continuously fluctuate in a building as its population changes.

DCV continuously monitors each floor in a building and automatically adjusts outside air ventilation rates. This is achieved by using controls and variable frequency drive (VFD) technology as needed, while still meeting ASHRAE ventilation standards. By optimizing the amount of outside air coming into the building, there is less air that has to be heated or cooled, resulting in a reduced load on the HVAC system.

To ensure the solution was as effective as possible for the company, the McKenney's ACS team installed CO2 monitors in the building, added custom programming for certain aspects of the project and reprogrammed the existing controls system to effectively integrate the DCV solution.
