Delmatic Lighting Controls Help Rochdale Borough Council Reduce its Carbon Footprint

Rochdale New Municipal OfficesWith sustainability at the heart of the design of Rochdale Borough Council’s new development at Number One Riverside, a Delmatic lighting control system is playing a key role in minimising energy consumption and carbon emissions.

Number One Riverside comprises two S-shaped six-storey buildings joined by an atrium with link bridges at every level. When complete it will bring together around 2000 council staff from more than 30 buildings, saving over £28m in ongoing maintenance costs. It is also designed to reduce the Council’s carbon footprint through a number of energy-saving and other sustainability measures.

The lighting, for example, is linked to a Delmatic DALI bus-wire lighting control system linked to a central PC. Full emergency testing and monitoring is also provided throughout.

The lighting in all internal and external areas is addressable and the lighting is controlled in relation to daylight, presence and absence. This high level of addressability within the system has enabled the designers to establish control parameters that best suit the design and usage of each space. The dimming function is also being used to provide various design illuminance levels in different areas, depending on the activities within each. This creates a highly flexible system that can be easily adjusted should the functions within a space change.

Lighting is divided into four zones, using a Lon router for each zone. The DALI buswire modules are then grouped together at each level within a composite panel. In areas where there are no false ceilings, flush sensors are set into concrete soffits or installed within continuous luminaire troughs.

Other sustainability features of the building include solar thermal and biomass heating, photovoltaic power generation and rainwater harvesting.
