It is an alarming fact that many building energy management systems (BEMS) have either never been serviced or have received little or no maintenance in years. Some will not even have been reset to compensate for changes to a building’s layout or occupancy patterns. To enable users of its systems to address this potentially costly problem, a comprehensive BEMS audit should be carried out.
By reducing energy and maintenance costs, audits should generally pay for themselves within a year — sometimes far sooner. Moreover, they will usually lead to improved comfort conditions for a building’s occupants. If the BEMS controls cooling towers or a hot water system, it could also help ensure that the risk of legionellosis continues to be effectively combated. Invariably, the service will increase end-user confidence in the building energy management system.
