Lighting control helps raise Energy Performance Certificate from D to B

Ex-Or, lighting control
The installation of an Ex-Or lighting-management system has helped reduce lighting costs by 40% in this office of National Savings & Investments.

As part of extension and upgrading of one of its offices in Blackpool, National Savings & Investments has achieved a 40% cut in lighting energy consumption by installing an Ex-Or lighting-management system. Lighting control is one of several technologies used during the upgrade, giving an overall annual reduction in CO2 emissions of 51 t and a saving on energy bills of £13 000 a year. The Energy Performance Certificate has improved from D to B.

The MLS digital management lighting system was specified by M&E consultation Steven A. Hunt Associates of Liverpool and was installed throughout the renovated parts of the building in open-plan office areas, conference areas and some corridors.

Communicating presence detectors share information on occupancy patterns throughout the building.

Steve Hunt explains, ‘NS&I wanted lighting control, but we wanted to take this one step further. We wanted to design in lighting schemes that would effectively illuminate common working zones and designated exit routes — from work station to exit or washroom facilities, for example.

‘We have specified this system in other schemes, so we knew it was completely capable of achieving these aims for us.’
