ABSTRACT
Building automation systems and metering systems are an enormous source of valuable operational data. However, it is rarely put to use, as facilities professionals do not have adequate means to collect and manage the data. The information is lost and decisions are made without solid operational facts, resulting in underperforming buildings and physical plants. An Enterprise Energy Management System (EEMS) addresses this by collecting all of the operational data from building systems, organizing it, and providing users with highly interactive access to the information contained within the raw data.This entry highlights the key functional requirements of an EEMS, and focuses on the complexities of collecting data from the many disparate sources and making it a highly valuable information source for operators, engineers, technicians, and management.
