2.6.5 Installation of a Building Energy Management System (BEMS)
Description
BEMS are computer-based systems that help to manage, control and monitor building technical services (HVAC, lighting etc.) and the energy consumption of devices used within the building. They provide the information and the tools that building managers need both to understand the energy usage of their buildings and to control and improve their buildings’ energy performance.
Benefits
Increase energy efficiency
Energy savings between 5% and 40%
Improved environmental conditions
More efficient use of staff
Improve fire, security and other emergency procedures
Improve standards of plant/building performance
Improve the management of the building
Limitations
It needs a skilled operator
It requires commitment at all levels throughout its operational life to maintain maximum effectiveness
Economic assessment
Higher initial costs for design and installation. Operation and maintenance costs might be higher compared to simpler management systems. However, the BEMS is also capable of reducing overall costs through improved energy efficiency and more efficient use of staff.
