Cathedral House

In 2016 we commenced a small LED pilot project in the main GF entrance and corridors. Since then LED has been rolled out to the whole building, the final phase in the song school being completed in early 2023. By phasing the roll-out we have benefitted from falling prices and improvements in LED efficacy such that the payback is typically now 5yrs for LED panels. Adding motion sensors has created additional savings. Total number of fittings has been reduced by 20% and kW/hr demand by 69%. The work has in effect been funded by the continuous ‘recycling’ of energy bill savings and feed-in tariff income from our onsite electricity generation.

The Cathedral

The Cathedral presents a greater cost challenge for LED lighting because most existing fittings on dimming circuits linked to 30yr-old central control packs. As a low cost short-term measure, we have re-lamped the shop, greeting area and Nave without materially compromising the system. This alone has reduced demand by 15% but we ideally need to undertake the full upgrade to LED before 2025.

Externally the old floodlights have not been used since the 2008 recession. New LED lighting was, however, added to the bell tower in 2017. This consumes minimal power and has a variety of colour options enabling us to illuminate the tower to mark special occasions and causes.
