Luminaires from Zumtobel Group companies Zumtobel Lighting and Thorn Lighting have made an important contribution to the aesthetics, environment, and sustainability credentials, of the Spire Nottingham Hospital in Tollerton, Nottinghamshire.
The two companies have supplied a range of fittings to illuminate all areas of the 58-bed hospital, including the main entrance, offices, consulting rooms, operating theatres, corridors, bedrooms, and nurse bases.
The £60 m facility is a new two-storey building with external single-storey buildings, service yard, 300-bay car park, and access road, complete with roof plant deck and ground floor plant rooms. It has five theatres, an endoscopy suite, a 20-room outpatients’ department, and an oncology suite, plus an advanced radiology department.
Zumtobel Caela pendants, featuring ‘edge-lit’ LED technology, chosen for their flexibility and aesthetic qualities, illuminate the main entrance. Zumbtobel said: “Caela’s precisely processed diffuser material enables precise dispersion of the light emitted, and the luminaires can also turn 355° and tilt 45° so several luminaires can form a curve, wave, or architectural feature. Zumtobel Slotlight Infinity, in the main entrance and throughout the en suites and circulation areas, creates ‘a continuous flow of illumination with no shadows’. Additionally, the en suites utilise Zumtobel Panos Infinity and Panos Evolution recessed LED downlights.
Zumtobel Lightfields Evolution was selected for the consulting rooms and Lightfields Evolution mini for the bedrooms to deliver ‘a glare-free light’, while the operating theatres incorporate Zumtobel Clean Advanced LED ‘to protect against contamination, including airborne dust particles, bacteria, and viruses’. A continuous, precision-formed, foam non-ageing seal between the cover and luminaire housing, and the luminaire and ceiling, ‘ensures a perfectly tight joint’. Trouble-free operation in positive and negative pressure containment rooms is ensured, as is IP65 protection from below, while internal catch locks prevent particles from accumulating on external fastener components. Cleanly mitred corners, precisely welded joints, and precision workmanship, further enhance protection.
Other Zumtobel luminaires used include Resclite & Puresign, Sequence, and Slotlight II RGB in the meeting rooms, ML5 for offices, Helissa on the stairs, and Supersystem spots at the nurse bases.
Zumtobel’s Litecom lighting management system is being used for the emergency lighting, and to optimise the lighting visual comfort and energy efficiency-wise in bedrooms, corridors, the board room, and main entrance. From control of individual rooms to several floors or whole buildings, the system’s functions and dimensions can be configured to suit the user, with control via conventional switches and Zumtobel control units, smartphones, tablets, or other computers. This includes dimming luminaires, saving lighting scenes, and controlling screens, windows, and blinds. Other functions, such as daylight-based lighting management, are covered by optional apps. Glare protection is also integrated into via scene call or manual, independent adjustment of the blinds and slat positioning.
Zumtobel says the resulting ‘extremely efficient luminaires’ achieve maximum energy savings, reducing energy consumption by 25 per cent through the use of luminaires fitted with electronic control gear with a dimming function. Presence detectors and switch-on times stored in Litecom’s central building calendar can yield additional potential savings of 20 to 40 per cent.
