CASE STUDY - LIGHTING
Edinburgh Leisure SUMMARY ● Annual lighting costs reduced by: ● Energy savings: ● Re-lamping cycle extended to: ● Enhanced lighting control A range of facilities operated by Edinburgh leisure have benefited from a combination of maintenance-free lighting and enhanced lighting control, supplied by Chalmor. These benefits include reduced energy costs, to the tune of £9000 per annum, extended maintenance cycles and enhanced visibility through whiter light, higher lighting levels and improved distribution.
Portobello Baths At the Portobello Baths, for example, energy efficient lighting systems have been installed in both the small pool and the main pool. Existing lighting in the small pool was provided by 20 x 250W high intensity discharge light fittings, which was usually left on from opening time until the pool closed in the evening.
£9000 66% 14 years
The Endurance fittings are linked to Chalmor Autolux lighting controllers, enabling the lighting to be switched on and off in relation to the occupancy of the pools, providing further savings.

As a result of these changes, Portobello baths has made significant savings in its total life-cycle costs. For example, the annual electricity for lighting across the two halls lighting has been reduced from 64,700 kWh to 21,700 kWh, representing an energy saving of 66%. Additional benefits accrue from reduced lamp disposal costs under the WEEE Directive.
Ainslie Park Leisure Centre Similar benefits have been achieved at the Ainslie Park Leisure Centre, where lighting has been upgraded in the sports hall and the pool hall. Installation of new lighting has also included re-positioning of light fittings to increase lighting levels and provide more even distribution.
In the main pool area, the positioning of ventilation ducting prevented direct downlighting, so uplighting to the ceiling was provided by 24 x 250W discharge fittings, again switched on early and left on all day. In “Chalmor’s both halls, all of the fittings solution replaced are mounted very high, making access difficult and existing lighting with disruptive and leading to 150W Endurance extended periods between long life, high re-lamping.
In the sports hall lighting was provided by 80 twin 55W fluorescent light fittings, manually switched in runs. These have been replaced by 40 x 150W Endurance fittings. In the pool hall, lighting was provided by a combination of 5 x 400W and 16 x 250W discharge fittings. These have been replaced by 27 x 150W Endurance fittings.
