Delmatic is supplying a comprehensive DALI lighting management system for the University of Greenwich’s new School of Architecture, Design & Construction.
The system enables individual addressing, switching, dimming and monitoring of DALI luminaires, in conjunction with presence-related and daylight-linked control of lighting groups from DALI presence detectors and multisensors.
The 16,500 m2 Stockwell Street development comprises two linked buildings arranged in a ‘finger’ layout with internal courtyards allowing daylight and natural ventilation into the spaces.
The buildings are designed to achieve high standards of sustainability to meet the criteria of BREEAM ‘Excellent’ and incorporate elements such as energy-efficient systems, solar panels, and “living roofs”, where wildflowers and other plants will create a wildlife haven at the heart of Greenwich town centre, within a UNESCO World Heritage Site.
The control of the lighting will play a key role in meeting the strict energy efficiency targets, and the Delmatic system was specified by consulting engineers Hoare Lea and is being installed by contractors SES.
Lighting is controlled throughout the building, using different control strategies in different areas. Many of these areas use suspended luminaires, with Delmatic’s DALI buswire modules enabling individual addressing, switching and dimming of the luminaires via a common Dali buswire.
DALI multisensors and presence detectors are installed throughout the building, many of them mounted within the suspended luminaires, to provide presence-related control and dimming in relation to daylight levels at the perimeters of the building. DALI scene-set panels are used extensively to provide local scene selection and adjustment of lighting levels. Solenoid water valves in the toilets are switched via a Delmatic DALI One Relay which relates water use to occupancy of toilets.
The Delmatic system monitors emergency lighting throughout the building, even in areas such as plant rooms where the general lighting is not linked to the Delmatic system. This is achieved by using DALI Buswire modules to address and monitor DALI emergency monitoring devices.
Delmatic worked closely with SES, producing CAD installation drawings detailing the location and application of hardware.
