What are Building Energy Management Systems?
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.
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 bills.
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 save 10% on the total energy costs of a building.*

Key BeMS capabilities
Information and tools for managing costs and eliminating energy waste
Monitoring and targeting
Measure, maintain performance and identify opportunities for reducing energy consumption
Enabling fast response to business-critical plant, equipment and process faults for minimal down time
Observe, assess, control and act through remote communication with the site at all times
Secure backup of all versions
Enabling 24/7 remote support, removing the need for dedicated on-site engineers
Flagging maintenance and service needs to avoid unnecessary preventative work
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
Microcomputer controllers receive signals from field devices and take action to control plant equipment in line with their programmed operating parameters
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
Send or receive data directly to controllers for either local or remote control and monitoring
BEMS Energy Saving and Maintenance
As BEMS specialists, Sphere Project Solutions are passionate about ensuring a building is performing and achieving its required internal environmental conditions whilst using the least amount of energy.
Fortunately, the high quality BEMS solution providers we work with include within their service portfolio a building performance report, detailing how much energy and money you are saving year-on-year.
BEMS Energy Saving and Maintenance packages typically include:
Planned preventive maintenance options
Maintenance plans to suit you and your building needs
All maintenance works carried out by BEMS system qualified engineers
Ensuring the BEMS control system is operating in an optimised and efficient way to reduce energy consumption
Carrying out any system upgrades that are required
Creating and managing BEMS control system performance and energy performance alarms, allowing you to monitor the building in real time
Providing full reports of the building performance after each routine site maintenance visit.
