Charterhouse School, Godalming, Surrey

Charterhouse School improves sustainability and saves 70% on energy use with LED lighting and controls.

Founded in 1611, Charterhouse School is one of the UK’s leading independent boarding schools. Set within an inspiring 250-acre campus, they provide education to over 800 pupils aged 13 to 18. Powercor was asked to implement a new lighting solution in their extensive sports centre. They wanted to be able to quickly adapt lighting for each sport played across their facilities, as well as optimise the environment for pupils during their exams.

Charterhouse School wanted to improve the sustainability of their energy use and create a productive environment for their pupils.

Because of this, Powercor implemented their award-winning automated metering technology to capture energy consumption data. This technology reports Charterhouse School’s electricity in kWh, cost and CO2 emissions and allows you to analysis their energy consumption.

The initial area for review was their busy sports centre which hosts a variety of sporting activities as well as pupil examinations. They were aware that lights were often left on when the sports hall was not in use and in order to become more sustainable by using less energy, we designed a system to suit their needs.

As a result of the installation of LED lighting and controls, Charterhouse now enjoys improved lighting levels whilst also saving money.

Powercor installed Philips LED Lighting, including Gentlespace Luminaires, and the Philips Dynalite Control System to ensure that the lighting could be easily controlled and quickly adapted to the sports activity taking place.

Presence detectors have also enabled Charterhouse to reduce energy wastage and costs as lights were automatically turned off when the halls were not in use.

Energy Saving

Achieved a 70% energy saving. (52,080kWh per year)

Lower costs

Annual running cost reduced by £6,287 per year.

Intelligent design

Lighting scenes can adapt quickly by a touch of a button.

Sustainable design

Lux levels can change for the activity hence making more energy/cost savings.

Powercor has not only improved the quality of lighting across the school but also helped us deliver on our sustainability objectives.
