The IS Ltd has supplied a CP Electronics Rapid lighting management system to help HFC Bank improve lighting conditions and reduce carbon emissions at its head office in Winkfield, Berkshire. The system is also reducing the whole life costs of the lighting by maximising energy efficiency, reducing maintenance costs and providing integrated automatic self-testing of emergency lighting.
The three storey office building has 2.8m high coffered ceilings and was previously using high pressure sodium uplighters throughout the office areas. These provided very variable lighting levels and proved to be expensive to run. In keeping with its environmental policy, HFC commissioned M&E design consultants PSH Consulting to design a new lighting system.
PSH specified direct/indirect luminaires using T5 fluorescent lamps to provide an even spread of light with good glare control and controlled contrast between the working plane, walls and ceilings. The lighting is linked to a Rapid control system to minimise energy consumption through daylight linking and presence detection.
“This was a challenging project and we selected The IS Ltd because we knew we would be able to rely on good support,” explained Charlie Cross of PSH. “The Rapid System also proved to be the most cost-effective way of delivering the high level of control required by the client.”
As well as enhancing control, the Rapid system monitors the status of all lamps and enables HFC to fine-tune its lighting maintenance strategies. In addition, any future minor re-configurations of the lighting can be carried out via the software, while major re-configuration is simplified by the plug in nature of the control modules. This is a particularly valuable feature at the Winkfield office, as there is no ceiling void and all cabling is in the floor void of the storey above.
In addition, the lighting management system incorporates TridonicAtco’s EM Pro emergency lighting modules linked to the central control software through a DALI interface. This enables HFC to automatically test emergency lighting and maintain a detailed log of testing in compliance with health and safety requirements.
