Salisbury Group recently implemented an initiative designed to ensure its office locations incorporated a comprehensive review of energy reductions and monitoring.

The dedicated specialist team oversaw the specification of lighting, solar film and smart meter installation. The initiative included a review and upgrade of the lighting to the rest of the estate.

The effective lighting design combined with the solar film installation improved the overall office environment, staff experience and has improved productivity. There was also the benefit of greater lifecycle – meaning fewer failures and a lower number of maintenance call-outs – as well as significantly lower energy consumption. The equipment solutions deployed were from leading UK and European based manufacturers such as Philips.

Subsequent results having monitored via the smart meters indicated that average savings were a remarkable 39% during the first year after the refit was completed. It was therefore a fairly straightforward decision to make to retrofit the building infrastructure.

The programme of retrofitting further sites will save between 30% and 60% on lighting expenses, representing significant ROI potential.
