THE UNIVERSITY of Oxford has become the latest client to demand ultra low-glare lighting for its latest building project.
The move is increasingly seen as an industry trend by major clients who see low-glare as a key differentiator for quality interiors.
The University’s brief for its new Norman Foster-designed Manor Road Building called for high performance and excellent aesthetics that would not compromise the original Foster visual lighting effect, while providing a more sustainable higher education facility and a perfect environment for learning.
The Manor Road site is home to timetables and building information for staff, students and visitors who are based at and attend events in the building. The Manor Road Building is home to several units of the Social Sciences Division and also houses the unified Social Science Library.
To maintain as much of the original design aesthetic as possible, the majority of luminaires have been supplied in custom 4m lengths and finished in black. For the offices Zumtobel’s MIREL Evolution, was chosen as the light source is not visible when looking across the room.
The unique LED optics combine directional light distribution while maintaining a value of UGR < 16.
Light guided via Zumtobel's advanced Quadrification Lens Optic (QLO) allows for high lighting quality, perfect glare control and batwing light distribution.
The Light Fields luminaire, with its minimalist, unobtrusive design has been installed in the lecture theatres. Its micro-pyramidal optic is precisely tuned to suit the distribution characteristics of the LED lighting points.
This guarantees glare-free light (UGR < 16 and L65 < 1,500 cd/m2) with a highly diffuse light distribution.
The luminaire has an efficiency of 120 lm/W at 4000 K.
Control is provided by Litecom lighting management system which can be controlled via conventional switches and control units, smartphones, tablets or other computers. The LIitecom lighting management system is being used in conjunction with a 360-degree Skyscanner on the roof of the building to deliver optimised visual comfort and energy efficiency.
The Skyscanner sends environmental information to the software enabling the setting of specifically designed brightness scenes by room or area to create defined atmospheres based on the purpose of that space.
Robert Gregg, principal electrical engineer, University of Oxford told Lux: ‘It was important for the university to look at the replacement of the existing lighting system which was problematic with large scale failures and had become a burden on the maintenance budget.
‘It was essential that the lighting system was fit for purpose and the lit environment was of upmost importance to the university.
‘The ethos behind the project was to deliver a sustainable solution through design and use of appropriate luminaires and controls whilst also complementing the original design from Sir Norman Foster.
‘With over 2,000 luminaires to be installed, the installation is still ongoing and is approximately 75 per cent completed. We look forward to seeing the project completed towards the end of 2019’.
