Continuous Commisssioning of a Multipurpose Facility
MetadataShow full item record
This paper presents a case study for the optimization of a multipurpose facility in a school district. The facility is a single-story building with a total conditioned area of 35,571 ft2. It contains a full size basketball court, concession stands, storage areas, restrooms, and a few offices. The building was designed to accommodate up to 5500 people for sporting events, commencement exercises, and meetings. The commissioning process identified many energy saving opportunities, including a critical sensor failure which led to a significant amount of simultaneous heating and cooling based on the existing sequence of operation (SOO). Since this is a rather common control sequence, the solution implemented in this case study has a broad application in many buildings that have similar SOO. Other major adjustments and modifications for the chiller and boiler plant and building HVAC systems operation are discussed in the paper. Measured result indicates approximately $120,000 annual cost savings as a result of the commissioning process, with a simple payback of less than 3 months!
