CASE STUDY Comfort Meets Sustainability at UK’s Ealing Hospital Challenge To provide an indoor and outdoor LED lighting solution for Ealing Hospital including LED luminaires, sensors and controls that substantially reduces energy cost while providing an appropriate and comfortable lighting environment. Solution The extensive hospital upgrade included installation of 38 variations of luminaires with different lumen outputs, optics, dimming/sensor controls, and integral emergency packages. The luminaires, sensors and lighting controls were installed in wards, waiting rooms, circulation areas, loading bays, cafeterias and reception areas. Fixtures in the imperial ceiling were replaced with bespoke recessed luminaires — a far less expensive approach than replacing the entire suspended ceiling. Benefits and Results Ealing Hospital officials determined that the LED lighting upgrade reduced energy use by approximately 50%? The complete upgrade was performed in 12 months. Return on investment is estimated to be reached in 5 years. All waste products were disposed of in line with WEEE legislation. An LED renovation of a hospital in the UK reduced lighting energy usage by approximately 50% while creating a lighting environment that is more conducive to healing. Challenge Due to their round-the-clock operation and high lumen output requirements, hospitals devote a great deal of their energy usage to lighting. According to the U.S. Department of Energy, lighting can account for 44% of a hospital’s electricity bill – nearly double that of a commercial building’s. In this light, it is no surprise that hospitals in many parts of the world are updating their lighting systems to LEDs to reduce their operating costs. Last year, the London North West HealthCare NHS Trust, one of the UK’s largest care trusts that serves over 850,000 patients and employs 8,000 people, spent 9% of its total budget on energy. In the interest of reducing lighting energy and maintenance costs to relegate those savings to other forms of health care services, the Trust secured government funding to upgrade its Ealing Hospital in Southall, Greater London, to LED lighting. The Trust partnered with the Dextra Group (Dorset, UK) to provide luminaires, controls and sensors for the upgrade. One of the substantial challenges involved the presence of imperial ceiling grids throughout the hospital, a size that is currently not offered in standard European lighting products. Rapid installation was also considered a necessity for the lighting upgrade. “When we accepted the 2014 Lux Award for Manufacturer of the Year, the judges described our ability to deliver custom product rapidly and in large quantities as ‘remarkable.’” We have recently expanded our design and manufacturing facilities to provide the fastest delivery times. —— Rupert Martin, Group Chairman and Owner, Dextra Group plc CS117 Comfort Meets Sustainability at UK’s Ealing Hospital Case Study ©2015 Lumileds Holding B.V.

All of the luminaires were designed for rapid installation and minimum interruption of work areas using cable flex and click ceiling rose design. In the wards, corridors, stairwells and cafeterias, custom For outdoor areas, the Amenity Plus LED luminaires with LUXEON 3535L LEDs provide 1500 lm or 2000 lm with light output ratios of 80%, matching the performance of fluorescent sources at a fraction of the energy cost. DEXLED recessed luminaires using LUXEON 3535L LEDs, with imperial dimensions of 1220 x 610 mm and 610 x 610 mm, were manufactured and installed. Due to the wide range of Benefits and Results lumen outputs achieved with the luminaires, fewer overall Ealing Hospital officials determined that the LED lighting fixtures were required than originally installed.

The MODLED is compliant with BSEN 12464 glare limitations for visual comfort. Other luminaires used throughout the hospital included the Graduate Surface LED and Protec LED downlights, using Philips Fortimo DLM Flex modules with LUXEON 3030 2D LEDs.
