WHAT WE DID
-
Our first task was to install two of our data monitoring devices – one positioned in the main entrance and the other positioned for the corridor/stairwells. Devices were installed for ten days collecting relevant data based on how long lights are on for in relation to how often movement was detected.
-
It was found that by using sensor-controlled lighting in these areas, we were able to reduce the energy consumption of the lighting by 77%, saving a total of approx. 225,894 kWh over 5 years. This amounts to a cost saving of £47K (based on energy pricing being around the £0.15 / k Wh)!
-
For carbon footprint reduction, we estimate a total reduction of around 57,800 kg worth of CO2 could be saved.
-
All existing light fittings were removed and safely disposed from site.
-
27 new modern, stylish fittings were installed – 13 of which had an integrated emergency pack to ensure total safety.
-
New fittings were equipped with occupancy sensors to ensure they are only lit when necessary, along with 10% dimming function when no occupancy is detected. This reduced the energy consumption to an absolute minimum while the building benefitted from never being in total darkness.
