DESCRIPTION
39% of the total energy used in a building is wasted.* But 84% of a building's total energy consumption could be efficiently controlled through an effective Building Energy Management System (BEMS). For a lot of businesses, the working environment and energy used day-to-day is given hardly a thought, aside from occasional adjustments to the air conditioning, or shock at the size of energy bills. However energy consumption in non-domestic buildings is often, quite literally, out of control. But while signs such as a steady increase in building operating costs and reduced day-to-day building comfort may appear impossible to fix, they are the side effects of a poorly performing BEMS; and are very much correctable.

For many businesses, aside from the occasional adjustment to temperature set points, the working environment and daily energy use is hardly given a thought. Moreover, the cost of energy bills are simply accepted and the nego@a@on of lower tariffs can appear to be the only op@on.
However energy consump@on in non-‐domes@c buildings can be significantly
reduced through bePer use of the installed BEMS.

The side effects of an incorrectly configured BEMS can include a steady increase in building opera@ng costs and a reduc@on in day-‐to-‐day building comfort.
However, by simply re-‐configuring the BEMS, many of these performance issues
can be corrected and may result in significant savings in a short @me frame.

What Causes a BEMS to FuncAon IneffecAvely?
Designed to func@on automa@cally year on year, a BEMS solu@on will work well controlling the environment it was configured for.

However, most buildings are subject to frequent changes in use. It takes @me and
skill to configure a BEMS to control an environment. If the physical landscape or the use of a controlled space changes so
must the configura@on of a BEMS.
Typical changes that affect the system and must be accounted for include:

• Set points remain unchanged and sensors placed inappropriately or not moved at all.

Taking Back Control of Energy Usage
At first glance, taking correc@ve ac@on on a BEMS can appear costly and complex.
But a full system over-‐haul is o7en not required and payback on remedial ac@ons
can be easily demonstrated.

In many cases correc@ng the inefficiencies in a building's energy use can be achieved with liPle investment; by simply op@mising the exis@ng BEMS se^ngs.
The first step? An Energy Audit, to establish where and how savings can be made in rela@on to building use and current system performance, it’s the best step towards taking back control of the energy use.

However, an audit should not be the only step if a business wants to maintain on-‐going
savings.
Maintaining Control of Energy Use
Once remedial work has been undertaken and the BEMS is working as it should, it can't fall out of mind or the original inefficiency issues will re-‐emerge sooner than you think.
To maintain on-‐going energy efficiencies requires a BEMS to be periodically reviewed, monitored,
op@mised and repaired.

Trend Approved Partners (approved BEMS installers) or Trend Control Systems Ltd offer solu@ons to manage a BEMS on a business's behalf and so prevent a disjointed approach to on-‐going maintenance.
As a result, businesses in non-‐domes@c buildings with a well maintained BEMS will be in control of their energy usage, occupancy comfort, carbon footprint and crucially will be economically efficient regarding energy costs.
