“Matalan has made the commitment to install

stores have shown a considerable reduction in
energy consumption of circa 20% and this is
reflected in our energy bill which has decreased
dramatically since implementation.”

The
Project
The ‘WEMS System’ directly controls
and monitors Matalan’s lighting,
heating and cooling plant, removing
the possibility of human error and
minimising waste energy. This
incorporates sales area lighting, backof-house lighting, external lighting,
air handling units (AHUs), over-door
heaters, gas-fired heaters, split air
conditioning units and electric panel
heaters.
Among the innovations at Matalan, is a
wireless key switch to ensure a minimal
overnight base load with regard to
lighting. When the keyswitch is unset,
the system enables a level of lighting
adequate for stocking and cleaning
prior to the store opening. Furthermore,
modulating control oversees any
heating or cooling actuators and
dampers with regard to the AHUs, while
gas-fired heaters are manipulated on a
trading time versus temperature dead
band basis.
This means that when the stock
temperature drops to a level 2°C below
the set point, the heating is activated
to heat the room back to the required
temperature.
The Results
In terms of financial return, measuring across
all 206 stores, financial savings to date are
estimated at a staggering £8.6m (taken from
the Sept 2016 report), whilst annual savings are
projected to be in excess of £1.5m.
Quick Facts
Since implementation:
• 20.74% Saved
• 79,119,648kWh saved
• £8,576,063 saved
• Over £1.5m saved annually
Now fully rolled-out, the company says
it will “close the loop” in terms of its
approach to energy management by
seeking certification to ISO50001.
