Continuous Commissioning: A Valuable Partner to Retrofit Projects
MetadataShow full item record
Continuous Commissioning (CC) or HVAC system optimization is not only a valuable stand-alone energy saving measure for commercial buildings, but it is also an important escort solution to retrofit projects. Energy retrofit projects typically achieve projected savings. But in cases where savings goals are not being met, optimizing HVAC system performance can be the difference in an underachieving versus a successful project. This paper presents a real-world study of pairing a CC project with an energy retrofit in a 107,000 square foot hospital building. Applying the CC strategy to an underperforming retrofit, projected energy savings were achieved and even increased. Additionally, by increasing supply air capacity, patients, staff and visitors now enjoy improved comfort conditions. This paper also explores the working relationship between an ESCO and a university research laboratory, whose combined efforts led to this remarkable turn around.
