Flex7 were able to provide a solution at Chapel Hill School that avoided having to use a fully addressable DALI system, which would have involved time consuming and expensive design and commissioning.
The £10.5 million project is a combined primary school and nursery. Its buildings are being constructed to operate at Net Zero, helping reduce their environmental impact whilst also playing a part in reducing the school’s energy bills. The project includes air source heat pumps, variable temperature heating systems, energy efficient LED lighting with daylight linking, and natural ventilation units with heat recover, and PV panels on the roof.
The client required DALI dimmable fittings in all classrooms, with 3 separate switchable & dimmable rows, one with daylight dimming. The light closest to the teaching wall also needed to be switched on/off separately when required, to avoid glare.
Each luminaire row needed a separate switch, so a separate LCM was used to control each one. All flex7 LCMs are suitable for dimmable and non-dimmable luminaires. Daylight linking was enabled in classrooms on all window rows, ensuring that lights only remain on in these areas when there isn’t sufficient daylight available. Luminaires will automatically dim up or down to maintain a constant light level (which is preset using a setup remote control).
Lighting controls were networked to share occupancy between rows, and a 2nd Switch Relay Distribution Box was used to allow for separately switching the luminaires closest to the teaching wall.
