Continuous Commissioning® Opportunities in Hospital and Laboratory Facilities
MetadataShow full item record
This paper compiles the Continuous Commissioning® (CC®) costs, savings, and opportunities implemented in 20 hospital and laboratory commissioning projects involving 48 buildings. The potential savings and costs from 25 CC assessments of 36 buildings are also analyzed and compared with the results of the implemented projects. The results from these projects including deficiencies and commissioning measures identified, and the cost and savings associated with CC are discussed. Case studies are also presented. For the 20 completed hospital and laboratory CC projects, the median (average) pre-CC energy cost was $3.44/ft2 ($4.46/ft2) [$36.98/m2 ($48.06/m2)] with median (average) energy cost savings of $0.84/ft2 ($1.19/ft2) [$9.03/m2 ($12.80/m2)] or 20% (26%). The median (average) potential savings identified in the 25 CC assessments were $0.41/ft2 ($0.44/ft2) [$4.36/m2 ($4.72/m2)] or 15% (16%). The lower savings identified in the assessments may result from the conservatism inherent in an incomplete identification of all potential measures during the assessments, or may result from some other factor.
