Benefits of Green Office Building
BMS is useful as a tool for improving
energy performance for a range of
building electrical installations and
technical services. It is conducive to:
• Saving on operating costs
• Central or remote control of building
equipment
• Efficiency in identification of
irregularities
• Save time in monitoring and
measuring power use
• Ease of evaluation, analysis and
planning for energy efficiency
Intelligent Building Management System
Overview for Office Building
A Building Management System (BMS) is a computer and network based control system which operates to monitor and
control a range of building electrical installations and technical services.
The range of building services controlled by a BMS may include: lighting, ventilation, air conditioning, security, access
control, fire services installations, lifts and escalators, plumbing, control panels and other engineering systems.
As the BMS is built on and operated using IT infrastructure, it
can save time on communications between the supervisory
controller and field controller. Meanwhile, the controllers
can use the system to readily consolidate data on energy
consumption and thus it subsequently leads to better
management of data information. The data generated can
be used for further analysis and planning of energy saving,
in forming a procurement strategy and even an
without on-site personnel inspection and measurement.

Apart from BMS, there are
several advanced technologies
available to reduce the energy
consumption and most of them
are commonly used, such as var-
iable speed drive, Light-Emitting
Diode (LED) and sensor system,
etc. (detail is available in
