How Building Owners and Managers can Take Back Control of their Energy use using a Building Energy Management System (BEMS)

Up to 84% of a building's energy consump@on could be controlled by a Building Energy
Management System (BEMS).

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:
Typical changes that affect the system and must be accounted for include: • Changes in building occupancy hours. • Causes services to turn on in unoccupied @mes.

• 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.
