LMOB used a diverse range of products at The Quadrant:MK including: ■ Under fl oor busbar and accessories -– Electrak. ■ Offi ce lighting – Thorlux Lighting. ■ Specialist lighting – Photonstar, Reigens, Whitecroft, WE-EF, Trilux, Hess, iGuzzini, Deltalight, Encapsulite.
■ HV and LV distribution – ICW Power using Schneider Electric equipment.
■ Rising power distribution busbars – Siemens. ■ Sub-main cables – Cleveland Cables. ■ Main electrical wholesaler – Edmundson Electrical.
than one reliant on traditional water supplies, and rainwater harvesting technology will be installed to fl ush toilets. Exterior solar shading panels will reduce heat gain, improve the effi ciency of natural ventilation and allow effective use of natural light. The building also uses the latest energy monitoring
technology to meet its objectives, and Network Rail has demanded maximum visibility and control of its energy use. Therefore, a building management system (BMS) has been installed to regulate and monitor heating, ventilation, air conditioning (HVAC) and lighting. The system’s software tools and smart metering system will enable Network Rail to extrapolate and analyse energy usage patterns in detail across an entire building and instigate changes where necessary.
Under control Going one step further, LMOB has also installed an intelligent lighting control system to further maximise energy savings. The lighting system utilises a Digital Addressable Lighting Interface (DALI) control system, which has been integrated within the BMS. The DALI network consists of a controller and one or
more lighting devices – such as electrical ballasts and dimmers – that have DALI interfaces. The controller can monitor and control each light by means of a bi-directional data exchange. Each lighting device is assigned a unique static address in the numeric range 0-63, making it possible to have up to 64 devices in a standalone system. Alternatively, DALI can be used as a subsystem via DALI gateways to address more than 64 devices. The system allows each area of the building’s lighting

use to be controlled separately, Marry explains: ‘Not only can lighting be turned on and off from fl oor to fl oor, it will only come on in occupied areas. It utilises a daylight compensating dimming system, and it is also possible to control the lighting in each individual workstation.’ The fi ttings installed in the building are both stylish
and energy effi cient. In the offi ce areas, products from Thorlux Lighting will work with the lighting control system, while in other parts of the building a range of specialist and architectural luminaires from Photonstar, Reigens, Whitecroft, WE-EF, Trilux, Hess, iGuzzini, Deltalight and Encapsulite have been used to complement the building’s unique design.

Above and beyond Each company working on the site has had to demonstrate a green approach to its work. This includes, where possible, recycling some of the materials from the demolished National Hockey Stadium and sourcing new materials locally. This means fewer lorries driving to site, and that those having to make the journey will have less distance to travel. In order to demonstrate its commitment to
sustainable practices, LMOB is working towards its ISO 14001 accreditation, which will help it identify and systematically reduce any harmful effects it may have on the environment, by developing processes to lower energy and raw materials use, reduce waste and pollution, and mitigate the risk of emergency situations. Marry comments: ‘We strongly believe in recycling and
have limited the amount of on-site waste as a result of our work wherever possible. We have also encouraged manufacturers and distributors to reduce the amount of packaging used to deliver items such as luminaires, and made sure that any packaging is recycled. This is in addition to sourcing 90 per cent of the products used from within a 20 mile radius of Milton Keynes and recruiting additional labour from the local area.’
