CILS turn buildings ‘smart’ via a smart lighting upgrade. Smart buildings leverage IoT and sensor technology to optimise energy usage and enhance the building’s performance. CILS offers a range of smart building solutions that improve energy efficiency while providing additional benefits.
Imagine an office building where lights, heating, and cooling are all automatically adjusted based on occupancy and area requirements, and small power outlets are automatically turned off when not in use. With our customised solutions, you can access data on space use, key assets or staff movement, room temperature. In addition, a smart lighting system is not only 90% more energy efficient but can also ensure the emergency lighting is up to regulation by automating monthly and annual compliance testing and reporting.

CILS refurbished the lights at Peterborough Register Office from the initial discussion and walk-round to removal and installation.
They produced detailed but easily readable plans, communicated excellently, got on with the job and made no mess. The difference it has made to our working environment is much appreciated.

Inspire Sports Village is a great example of a project where we invested our own money in order to provide a better sustainable position for the organisation, and also to provide the client who owns the building something that was future-proof. Those intelligent sensors could allow us to reduce further our cost base and be more efficient in the longer term.
Our savings are over 80%. It will provide a better lighting platform for the next 10+ years.
We want to save money so that we can reinvest into the organisation and into the community.

In a time when energy spend is ever increasing, securing NEEF funding has been very well received at WWL. This is all part of our drive to becoming more energy efficient and delivering LED lighting across WWL, significantly reducing our emissions and electricity consumption, and we were one of the first Trusts in Europe to utilise the Internet of Things within our light fixtures.
