Effective Lighting Controls Generate Energy Savings
of Up To 50% In Multi Storey Car Parks
Cooksey, Technical Director of Oxford Automotive Technologies believes that effective control of lighting in Multi-storey
and Underground Car Parks can reduce carbon emissions by up to 50% saving tens of thousands of pounds per year and reducing
much maligned light pollution.
any town or city in the UK at night and you can virtually guarantee that they are ablaze with light. This
comes from shops, pubs, nightclubs and, significantly Car Parks, be they Multi-Storey, or open plan type. Car parks are generally
lit 24/7 and 365 days per year, providing a safe, secure environment to leave a vehicle whilst going around your business.
has to ask oneself if it is really necessary to leave these lights on all of the time, especially when the buildings are unoccupied,
and whether it is more cost effective and kinder to the environment to install a control system to operate the lights only
average, a reasonable town or city in the UK can service between 5 and
25 multi-storey car parks, the obvious exception being London
which is home to hundreds.
perspective, a large multi-storey car park when lit 24/7 can use up to 950,000 Kw/H/year. This is a very significant amount
of electricity and, depending on tariff rates can equate to yearly running costs of up to £90K. Not only that, but the associated
Carbon Emissions will be around 400,000 Kg/CO2.
this by the number of Car Park structures in the UK estimated at 2,000
in England and Wales
and the figures are quite astounding.
has long been a feature of new office developments and commercial developments that lighting is only operated when a building
or even a room is occupied. This can be achieved in a number of ways from simple time switches, BMS systems and also proximity
detection by use of discreet PIR (Passive Infra Red) detectors.
is no reason why this type of system cannot be applied to a Car Park, as long as the system is robust and reliable, such that
car park lighting is only energised when a particular floor or zone is occupied, be that by a moving vehicle or a pedestrian.
