The installed lighting electrical load of the 784 light points is just 5.9W/m2, delivering significant energy and carbon savings compared to traditional office lighting installations. All of the lighting is fully addressable and controllable with links to daylight and occupancy sensors. Sensor and dimming settings can be adjusted to fine-tune the control of the lighting in relation to any changes in building usage. Under the Pay Per Lux agreement the lighting will be monitored online with annual reporting back to NUS.
Jamie Agombar explained: “The Pay Per Lux scheme enables us to delegate the responsibility for managing the lighting to those with the most expertise, while giving us predictable costs over a 15 year period. At the same time it ensures that we will continue to benefit from the best energy-saving opportunities with a guarantee that the required light levels will be maintained through the period of the contract.”
