About This Item


Full Description

Discusses methods for evaluating the savings of verifying the energy savings from energy savings performance contracting (ESPC). Goes on to discuss one particular monitoring technology, the use of in-place energy management and control systems (EMCS) to carry out this monitoring. Presents a case study of savings estimation in ESPC in an institutional building. Compares the savings estimates resulting from different monitoring methods plus the different processes of collecting and analysing data. The object is to investigate the use of the EMCS to collect the data specified in the ESPC measurement and verification protocols. States the results of the comparison are recommendations on how EMCS can be used most effectively for the particular applications of verifying ESPC savings and how EMCS results compare with other tools for calculating savings.
