Wireless lighting controls enable 25% labour cost reduction in hospital refurb

Moreover, the intuitive wireless design of the solutions, coupled with the consultative approach of CP Electronics experts, helped to make the installation process considerably easier, saving valuable time and money on the project.

Located in the Liverpool suburb of Broadgreen, Liverpool Heart and Chest hospital is a renowned medical facility that specialises in the treatment of heart and lung disease. 

 

One of the main challenges of the project focused around the design of the outpatient’s department which features three separate hallways intersecting to form a crossroads leading to the hospital waiting room. The difficulty here was that the lighting in each of the hallways was run on individual circuits. The consultant on the project wanted to address this by running them on the same circuit, since this would allow them to be switched on and off simultaneously, whichever entrance was used. Ordinarily, the contractor would need to re-wire the lighting back to the distribution board before installing the PIR-activated contactors used to operate the light fittings on and off. However, on this occasion an approach like this would have added additional complexity, cost and time to the project.

 

Wireless PIR presence detectors from CP Electronics were recommended as a means of reducing the amount of wiring needed on the project. Given that labour accounts for a sizeable portion of the cost on any project, any measure which enables a faster and easier installation can have a real impact. Only power supplies for the wireless PIR presence detectors were needed, resulting in a significantly reduced installation time. Using wireless PIRs saved a minimum of 25% on total labour costs, making them a worthwhile investment. From the perspective of the end user, in this case an NHS trust with limited financial resources, presence detectors help to avoid unnecessary energy consumption by activating the luminaires only as and when required.
