LED lamps in PricewaterhouseCoopers have achieved the highest commends from BREEAM

　　UK Building Research Establishment Environmental Assessment Method (Know as BREEAM) is often called the UK Building Research Establishment Green Building Rating System. Founded in 1990, BREEAM green building assessment method is the world's first and the world's most widely used. It is a set of evaluation criteria of green building but also the establishment of best practices in green building design. This should also be the most authoritative description of the environmental performance of building an international standard and a large number of world-renowned landmarks have adopted BREEAM assessment evaluation and certification system for green buildings, including the global headquarters of HSBC, PwC UK headquarters, headquarters of Unilever UK, London, Stratford Tower, Paris HE Métis plot Square, the German Central Museum of shopping centers.

　　Green Building Rating System under BREEAM is related to nine aspects, namely: management, health and comfort, energy, transport, water, materials, land use and ecology, garbage and pollution. Among them, the lighting throughout the building energy consumption accounted for at least 20%, and to use more natural light. It is clear that to meet this requirement, they should try to use more T5S and LED and control systems.

　　BREEAM excellent ceiling lighting requirements 8W/m2, the whole building has 33,500 square meters of open space office area , client area , conference rooms , restaurants and similar non- office space , control of DALI dimming and scene setting , presence / absence detection and daylight control , people work long hours and late-night overtime PwC , this means that you want to split the 400-500 people isolated lighting space, but in order to avoid a darkness around , but also to retain a third of illumination in the adjacent area to switch all circulation are maintained at 50 % of the light output.

　　PwC is located in the most crowded place in London, along Charing Cross Station, where some of the lighting infrastructures are big challenges, such as how to deal with the main entrance of the building, linear LED lamps on each side of continuous operation, using the existing cable ducts and control form, interspersed with additional devices to illuminate ribs spaced across the ceiling. ArcPad extreme double linear LED lamps installed on the underside of the lower beam across the atrium does not produce glare of the lights.
