A lesson in sustainable lighting management

Delmatic is supplying a comprehensive DALI lighting management system for a new 16,500 m2 development which will house the University of Greenwich’s Department of Architecture and Landscape from late 2014 .  The £76 million development, which is located at the heart of a UNESCO World Heritage site, is composed of two buildings linked around internal, open-air courtyards.
The Delmatic system controls lighting throughout the development and, through a combination of presence-detection, absence-detection and daylight-linking, will play an important role in meeting the energy efficiencies required to secure the project’s BREEAM ‘Excellent’ rating.
In 2012, the University of Greenwich was named the UK’s ‘greenest’ university by the prestigious “People and Planet Green League”[1] and the University’s continuing commitment to sustainability is evident in the new development which has already been awarded two prestigious BREEAM Innovation credits.    The development uses a combination of passive design features  - including  the UK’s largest landscaped roof gardens – and efficient systems to reduce energy demand, emissions and wastage.
Technology – DALI system
The Delmatic 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.  Different strategies are used across the development to provide flexible and effective lighting control appropriate to the particular area and the way in which it will be used.
DALI multisensors, presence detectors and absence are installed throughout the development to provide presence-related control and dimming of lighting groups related to daylight levels at the building perimeters.
Many areas are lit by suspended luminaires controlled by remote Delmatic DALI buswire modules which enable individual addressing, switching, dimming and monitoring of each luminaire via a common Dali buswire.
The system also includes DALI scene-set panels to provide local scene selection and adjustment of lighting levels.
The Delmatic lighting control system will also help the university reduce its water usage.  Solenoid water valves in the toilets are switched via Delmatic DALI Relays which relate water use to occupancy monitored by the lighting management sensors.
Emergency Lighting
The Delmatic system will provide comprehensive DALI monitoring of emergency lighting throughout the building, including areas such as plant rooms where the general lighting is not linked to the Delmatic system. This is achieved by using DALI Buswire modules which individually address and monitor DALI emergency devices.
