Abstract:
This research meets this growing need by providing building owners, utilities and program implementers with an analysis of existing building commissioning measures implemented through programs across the country.
Information on commissioning measures implemented under utility programs across the United States was collected from 11 utilities known to conduct EBCx programs. In total, data on 122 commissioning projects and over 950 commissioning measures was received. From this, a data set was constructed representing a variety of building types, sizes, ages and climate zones, and contained data on measure types, savings, and costs. For each building attribute (type, size, age, location), the top saving measures that account for 75% of the category’s savings were identified.
The results from this study may be used to inform utility program design. For instance, a utility may require that all EBCx projects investigate the key measures, at a minimum, as a way to promote greater savings. Another option is for utilities to promote an operational tune-up program that only focuses on these most commonly found measures. While a tune-up program would likely reduce investigation costs, the full benefits of EBCx, such as well-integrated systems that deliver comfortable conditions, would not likely be realized.
