Hertz loves the energy savings

Riegens, lighting, control
New lighting for Hertz at Heathrow has more than halved energy costs, with a 16-month payback period.

Lighting energy consumption has been more than halved by the installation of more efficient lighting for vehicle renting company Hertz at Heathrow. Calculated energy savings are 54%, amounting to £6841 a year with a payback of 16 months. The project includes the Drive fitting from Riegens and other Riegens luminaires.

The brief was to provide a more efficient lighting scheme in the reception areas, Gold Patrons collection point and fuel filling areas as part of a complete building refurbishment/fit-out of Hertz’s £2 million investment in its Heathrow operation.

Following a site survey and energy calculations, Riegens was included in the redesigned scheme by Rick Hawkins of Property Project Services, designers and project managers.

The Drive petrol-canopy fitting offering direct light distribution was used in the Gold Patrons area. Controls switch these fittings off during daylight hours and dim them when they are not in use during the night. Presence detectors switch the lights to full brightness as soon as a customer approaches to collect a vehicle.

The Drive fitting, which incorporates two 55 W TCL lamps also replaced existing HID fittings in the fuel forecourt areas, again with absence/presence detection controls.

The main reception area was completely refitted and redesigned using Riegens recessed DL-ECO downlights with two 14 W compact fluorescent lamps. These downlights can reduce energy consumption by 25% compared with equivalent compact lamps with high-frequency controls and savings of over 50% compared to electro-magnetic systems.

Capro recessed 600 mm-square luminaires were installed in public areas, controlled by absence/presence sensors.
