ENERGY EFFICIENCY


Significant energy savings can be achieved by using modern technology.


Once an Energy Audit has been completed, the information will give you a clear and un-biased evaluation of your organisations and identify all the major energy saving opportunities. The report will also give you estimated costs and benefits of particular technology solutions for example lighting. And in turn this will help you prioritise those areas most worth tackling.
Below you will find some of the more common Energy Efficiency Technology Solutions and a simple explanation of what they are.

BEMS – Building Energy Management System

Functions of BEMS

The four basic functions of a central, computer-controlled BMS are:

  • Controlling
  • Monitoring
  • Optimizing
  • Reporting

A BEMS normally controls:

  • Power systems
  • Illumination system
  • Electric power control system
  • Heating, Ventilation and Air-conditioning HVAC System
  • Security and observation system
  • Magnetic card and access system
  • Fire alarm system
  • Lifts, elevators etc.
  • Plumbing system
  • Burglar alarms, CCTV
  • Trace Heating
  • Other engineering systems
  • Fire alarm and Safety system
  • Manage the sensors of alarm

Benefits of BEMS

Building tenant/occupants

  • Good control of internal comfort conditions
  • Possibility of individual room control
  • Increased staff productivity
  • Effective monitoring and targeting of energy consumption
  • Improved plant reliability and life
  • Effective response to HVAC-related complaints
  • Save time and money during the maintenance period

Building owner

  • Higher rental value
  • Flexibility on change of building use
  • Individual tenant billing for services facilities manager
  • Central or remote control and monitoring of building
  • Increased level of comfort and time saving
  • Remote Monitoring of the plants (such as AHU’s, Fire pumps, plumbing pumps, Electrical supply, STP, WTP etc.)
  • Central or remote control and monitoring of building

HVAC – Heating Ventilation and Air Conditioning

Functions of a HVAC System

While there are many functions that a HVAC system serves, the primary function is to maintain a comfortable temperature in every room of a commercial building. This is done by the regulation of humidity, air flow, as well as temperature so that these parameters stay within acceptable limits. While this makes staying indoors comfortable, it also ensures that inhabitants do not suffer from health risks that reside in the categories of poor ventilation, heating etc.
By using a BMS system the HVAC can operate and monitor the performance of a HVAC system.

LEL – Low Energy Lighting

Getting lighting right is important for the energy efficiency of a building and the well-being of its occupants. Up to 60% of a building’s electricity use can be accounted for by lighting, while the right level and quality of light improves the alertness and accuracy of those working in it.
Many types are on offer from simple lamp replacements to large scale street lamp installations.

LC – Lighting Controls

Lighting controls vary from simple on/off switches to building wide, networked, control systems. They are equally appropriate to all sizes and types of buildings; it is just a question of choosing the most suitable solution.
Lighting controls offer further benefits than simply saving energy. Depending on the application they can improve comfort, reduce maintenance costs and impart greater flexibility to the use of a workspace.
