Any organisation seeking to reduce its carbon emissions should first take a closer look at its building energy management system (BEMS).
Owners and tenants of non-domestic buildings are under mounting pressure to cut their energy usage and carbon emissions. They are faced by the prospect of higher utility prices and ever more stringent legislation, not to mention public and stakeholder demands that they show high standards of corporate social responsibility.
So what should be the first priority for hard-pressed energy and facilities managers? The logical answer is that they should focus on those areas where large energy savings can be made quickly and easily. This will often mean looking no further than their building energy management system.
The principal role of a BEMS is to regulate and monitor heating, ventilation and air conditioning -- and often lighting too. A BEMS can efficiently control as much as 84% of a building's energy usage. By applying a range of control and monitoring routines -- both simple and sophisticated -- it is capable of operating the building services in strict accordance with demand, thereby avoiding unnecessary use of energy.
