A high efficiency lighting retrofit was completed on Cavan multi-storey car park which reduced operating costs for the council while improving the experience for car park users.
130kkWh of annual energy savings
Operational costs covered more easily
Before the project, in order to cover operational costs, 204 cars needed to be parked for at least one hour per day. Now only 67 cars need to park for one hour per day.
|Annual energy (kWh)||Annual costs (€)||Annual CO2 (kg)|
|Savings||130,000 (61% saving)||18,000 (60% saving)||74,000 (64% saving)|
The main objective of the project involved the replacement of 180 W High Pressure Sodium lamps with 70 W induction lamps. This was to reduce energy requirements and improve the lighting quality. IE Lighting was selected as the contractor for the project on a design and supply contract.
The following were also carried out as part of the retrofit design:
- Install 20 W LED lights for stairwells and lobbies, replacing 36 W CFL 2D fittings
- Combine efficient lighting with effective lux level and timing controls
- Maintain health, safety and security requirements
- Promote car park use with a well-lit interior
''The car park is so much brighter now. I feel safer using it''
’Initially, there was a requirement for 204 cars to be parked for a minimum of one hour per day to cover operational costs; this number is now 67‘’.
