Bringing a new level of versatility and sustainability to building controls
Delmatic connected lighting management systems enhance flexibility and save serious amounts of energy by connecting all energy consuming services to occupation using smart sensors and open protocols.
Delmatic systems use smart multi sensors throughout a building to control lighting based upon occupancy (presence/absence) as well as other factors such as the extent of natural daylight. The information from these smart sensors generates interactive graphical maps of occupancy and daylight which are then shared with other connected building systems so that not only lighting but also other energy-consuming services such as HVAC are related to actual occupancy patterns.
Pooling and sharing this real-time knowledge optimises the operational effectiveness of buildings and ensures efficient and economic use of energy. When someone enters a room, for example, a single connected sensor sends information to the lighting and VAV controllers which determine whether lighting is required or, for example, the VAV needs to be activated to heat or cool the room. When an area becomes empty the connected sensor alerts the relevant systems to conserve energy by switching off or reducing lighting, heating and other services in unoccupied rooms or even entire sections of a building.
The key to connected services is the use of open, international ISO protocols such as BACnet and LonWorks which enable seamless sharing of data between lighting, HVAC, solar shading, room booking, fire alarms, access and security systems.
Systems and products using proprietary manufacturers’ protocols are to be avoided as these can only interface in a limited way through expensive, custom gateways, while a ‘closed’ proprietary system also ties the client into lifetime support from a single supplier.
Connected systems not only share information and knowledge, they also share hardware and network infrastructure – so reducing capital and installation costs too.
Delmatic’s interactive maps provide “windows” into the connected services and display real-time information including lighting levels, lamp run-hours, lamp failures and energy statistics so enhancing operational efficiencies.
Despite the powerful connectivity of systems and services, connected controls are far from centralised solutions which determine how the services should operate. Instead, connected controls use distributed, organic intelligence and provide users with complete control over their lighting and services environment.
With Delmatic connected lighting management systems, building services can be locally controlled and adjusted via touchpads, touchscreens, IP phones and mobile devices. As a result, occupants can set levels of lighting, heating and cooling to suit their own preferences as well as control other amenities such as window blinds and solar shading within their own area – all of which makes for a more comfortable and enjoyable environment in which to live and work.
Implementing Connected Systems
Connected systems are being implemented on many major projects including commercial buildings such as The Shard in London, educational and research institutes including the Medical Research Council Laboratory of Molecular Biology (LMB) in Cambridge, and major infrastructure projects such as Crossrail across London.
The world-leading Medical Research Council Laboratory of Molecular Biology (LMB) demonstrates the positive impact of connected lighting management on a building’s operational effectiveness and energy-efficiency. The Delmatic connected system incorporates Dali presence detectors and Dali multisensors which provide absence detection and daylight linking (to maximise energy efficiency) and pass on real-time occupation data of individual areas to the BMS so that heating/cooling as well as lighting is linked to out-of-hours occupancy and only used where required. The connected system provides extensive real time monitoring of the installation including individual lamp failure, ballast failure and emergency monitoring failure of every luminaire in the building including lighting in plant areas and basement link tunnels.
Crossrail is the UK’s largest ever single public infrastructure development and currently Europe’s biggest construction project. Delmatic connected systems are providing intelligent, secure and energy efficient networked control and management of lighting within front-of-house, back-of-house and external areas at the key central London and Docklands stations.
Energy-efficiencies achieved through digital dimming, presence/absence detection, and daylight-linking in naturally lit areas are coupled with operational efficiencies gained through real-time management and monitoring. The connected systems link with other services including the UPS network, fire alarm and BMS – sharing information and linking systems through DALI and open protocol communications. The Delmatic systems connect with the station UPS networks to provide emergency light monitoring and testing via the Dali protocol as well as comprehensive monitoring of normal and emergency lighting across each site.
