Isambard Brunel Multi-Storey Car Park
Alec Rose Lane, Portsmouth, PO1 2BX

The Project
Named after famous 19th-century engineer, the Isambard Brunel car park in Portsmouth has 460 spaces. It is open 24 hours a day, seven days a week, and therefore requires a high level of lighting around the clock. When Portsmouth City Council was looking to reduce energy consumption at the car park, making the switch to energy-efficient lighting using ‘Save It Easy®’ was identified as an ideal solution.

Implementation
Using Save It Easy, Energys Services Ltd (ESL) installed 520 energy-efficient lamps over the various levels of the multi-storey car park.

Savings
The higher efficiency of the low-energy lamps, plus the more efficient control gear in the Save It Easy units, has allowed the car park to reduce its energy use in lighting by 49%, making annual savings of £17,573 on its electricity bills. As a result of the project, the car park has also successfully cut its carbon footprint by 45%, saving 87 tonnes of carbon each year.

Project Payback
Portsmouth City Council will achieve payback on the Isambard Brunel car park project in just 11 months.
