The use of EMCS in building monitoring: Experience from energy edge and LoanSTAR Programs

OSTI ID:105861
Monitoring building energy performance can provide important immediate feedback to building personnel in building commissioning, operation and maintenance. It also provides an essential ``reality-check`` and feedback (immediate and longer-term) in many utility efforts such as demand-side management impact evaluation, forecasting, and conservation measure technology assessment. However, monitoring can be quite expensive, often resulting in either the need to reduce experimental sample sizes (with resulting reduced accuracy) or to forgo monitoring altogether. Analysis of data from in-place Energy Management and Control Systems (EMCSs) may be an effective alternative to dedicated monitoring in many cases. EMCS-based monitoring can have several advantages: reduced cost due to the fact that the equipment has already been purchased and installed, an increased amount of available data, information on building operation, and an on-site data processing capability. The use of EMCSs for monitoring has been investigated at several sites within two different conservation programs: the Energy Edge Evaluation Project (new construction), and the Texas LoanSTAR Monitoring and Analysis Program (retrofit). The text that follows provides an overview of the potential role that EMCS-based monitoring may play in conservation efforts, and a summary of the findings of these investigations. The presentation at the National Conference on Building Commissioning will provide greater detail on the experiences with EMCS monitoring in the two conservation programs.
