Chelsea & Westminster Hospital LED Lighting Upgrade

Ferguson Brown were appointed to carry out the design and implementation of an upgrade programme to replace existing lighting with LED lighting throughout the hospital.

The Chelsea and Westminster Hospital is 20 years old, and occupies 7 floors. The lighting in approximately 80% of the building is the original installation, comprising mostly of 1200mm T8 lamps with high frequency control ballasts. There were bespoke solutions required for the architectural luminaires within the atria common areasand stairways.

Funding was received from the Department of Health scheme ‘Improving Energy Efficiency in the NHS’ to fund the design and installation of LED lighting.

Installation and Maintenance
The replacing ‘like for like’ concept minimised disruption and inconvience to patients and staff. Alterations to the existing ceiling were also kept to a minimum. Maintenance work and therefore costs will also be reduced as the LED arrays installed in the luminaires do not require replacing as would be the case for fluorescent luminaires.

Cost Savings and Payback
Thorn lighting undertook an evaluation of the cost saving per annum and payback term. Their assessment was that there was a energy saving cost of £96,562 per annum and a payback term of 4.7 years.
