Energy Management

A Building Energy Management System (BeMS) is an essential tool for achieving energy efficiency goals. Comprising intelligent software and hardware, it reduces energy costs, boosts environmental comfort, optimises plant control and lowers carbon emissions.


Energy management

A sound energy management strategy is vital to businesses and organisations for achieving financial savings and operational efficiency, enhanced occupier comfort and a lower environmental impact. It also ensures compliance with legislation, protects against rising energy prices and supply risks, and enhances corporate image.

Optimising energy efficiency

An essential tool for helping a business or organisation achieve its energy efficiency goals is a Building Energy Management System (BeMS) - an online computer-based control system for monitoring and managing buildings. Comprising intelligent software and hardware, a well designed and maintained BeMS will reduce energy consumption, boost environmental comfort, optimise control of plant equipment and deliver cost and carbon emissions savings.

As with any system, BeMS performance will only be as good as the quality behind it and the quality of its management. It is estimated that up to 90% of heating, ventilation and air conditioning building control systems are inadequate in some way, costing industry and commerce over £500 million per year in additional energy costs. With a well-controlled and managed BeMS in place, organisations can typically save up to 35% on their heating bills compared to a poorly managed BeMS, and 10% on the total energy costs of a building. *

Key BeMS capabilities

  • Utilities management: Information and tools for managing costs and eliminating energy waste
  • Monitoring and targeting: Measure, maintain performance and identify opportunities for reducing energy consumption
  • Alarm monitoring: Enabling fast response to business-critical plant, equipment and process faults for minimal down time
  • Remote monitoring: Observe, assess, control and act through remote communication with the site at all times
  • System backup: Secure backup of all versions
  • Remote access: Enabling 24/7 remote support, removing the need for dedicated on-site engineers
  • Condition monitoring: Flagging maintenance and service needs to avoid unnecessary preventative work
  • Multiple access: Using a web browser allows multiple users access to the system at the same time, such as managing directors, financial controllers, estates teams and energy managers

Main BeMS components 

  • Principal user interface

Incorporating a wide range of functions, the principal user interface can be used to:

  • Centrally manage large numbers of buildings, significantly reducing operating costs
  • Graphically monitor and control the building environment
  • Schedule and modify mechanical equipment operation
  • Collect, view and analyse trend and current information
  • Connect multiple stations together using the networking features
  • Troubleshoot and fine-tune the systems
  • Enable management decisions using information and reporting capabilities
  • Controllers

Microcomputer controllers receive signals from field devices and take action to control plant equipment in line with their programmed operating parameters

  • Networks

Devices communicate locally, across a wide area network or remotely from anywhere in the world using standard browser technology for full and continual access and control

  • Field devices

Send or receive data directly to controllers for either local or remote control and monitoring
