HOLY CROSS SIXTH-FORM COLLEGE

Staff and Students at Holy Cross College are extremely pleased with the results of Dextra Lighting’s modern solution for their renovated state-of-the-art library and classroom facilities. 

ABOUT THE CLIENTS

Holy Cross Sixth-Form College and University Centre in Bury, Greater Manchester, offers A-Level education and a selection of Undergraduate courses to a large student base of 2,200. It has been ranked as of one of the best colleges in the UK for their excellent staff and teaching facilities, with students consistently performing above the national average. Rated outstanding in its last OFSTED inspection in all performance categories, the college continues to strive to provide the best possible facilities for its students and staff.

In recent years, the college has made considerable investments into improving its facilities, with the latest project being the major expansion and upgrade of its library. Like the rest of its estate, the standard of the new library’s interior design was set high, aiming to achieve a fresh, modern aesthetic whilst providing all the core requirements of a university-style library. Holy Cross took on board staff and student feedback concerning the need for more

individual and group study areas, and incorporated ideas for more comfortable and functional furniture, improved lighting, and layout tailored to the students’ needs.

Lighting was to play a key role in creating a stimulating, open and welcoming learning environment, whilst generating substantial returns for the college through cutting electricity bills and improving its ranking in the Carbon Reduction Commitment Table. Upon the strong recommendation of DDA Building Services and Consultant Engineers, Dextra Lighting were selected for the project, to provide a unique, attractive and sustainable solution for the college. Over many years, DDA’s experienced and highly qualified team of Low Carbon Consultants and Assessors have specified Dextra Lighting’s precision-engineered products to provide quality, reliability and future-proof efficiency for its diverse clientele. Following the procurement phase, local contractors, Performance Electrical Ltd, carried out the installation.

THE BRIEF

To carry out the brief, Dextra Lighting needed to design, manufacture and deliver a bespoke system for the open plan library with classrooms separated by glass walls. New lighting was also needed for circulation areas and stairwells throughout the building. Given full design responsibility for the project, Dextra’s design team proposed a highly varied selection of luminaires to mirror the library’s contemporary style, layout, and unconventional ceiling.

The installation would also need to ensure visual comfort for prolonged hours of study and support the use of computer monitors by minimising glare and providing a uniform light distribution. With energy-efficiency in mind, the design was based on products using the latest LEDs and high-efficiency T5 lamps, whose performance is enhanced by Dextra Lighting’s advanced optic designs. Efficient, low-maintenance emergency lighting was to be provided in accordance to the buildings safety regulations.

THE solution

Primary Lighting – The MODLED Surface / Suspended

The attractive slimline luminaire was suspended from the highest point of the ceiling in a continuous run stretching across the main open plan area of the library. The suspended system has a striking presence and its appealing minimalist design harmonises well with the library’s decor. But beyond aesthetic appeal, the MODLED Suspended uses the latest Lumileds LEDs and advanced optics with 93% transmission to deliver similar or greater performance than fluorescent equivalents whilst operating at an impressive average of 113 luminaire-lumens per circuit-watt (Llm/w).

The versatile luminaire can be installed individually, joined into multiple run configurations, or be surface mounted onto different ceiling types, to suit the

architectural design of the building. The continuous run option, however, allows for a more a creative approach for lighting designers to explore. A total of 50, 1200mm luminaires formed a U-shaped run covering the entire area, joined at the corners by 90 degree blind units. Supplied in a 5000lm option from a range of outputs as high 13,600lm (across three body sizes), the luminaires were suspended 3 meters from the ceiling, with the length and the width of the  run calculated to achieve the desired light intensity and balanced distribution, whilst complementing other nearby lighting. A wide range of dimming functions, sensors and emergency options are also available with this product, offering increased flexibility to tailor each installation to the client’s specific requirements.

Accent Lighting – The Gyro-Light LED Recessed Gimbal Luminaire

As support for the main lighting, 40 Gyro-Light LED luminaires were fitted at the lower section of the angled ceiling, boosting light levels around the edges of the hall, whilst also providing a more focused light for the individual desk areas and computer stations. The luminaire’s attractive steel housing with powder painted white front surround (also available in black) and high-quality die-cast aluminium heads, offer both durability and an appealing contemporary touch to the interior.

Flexibility is at the core of this range, with a choice of either single, twin, triple or quadruple head configurations, allowing the Gyro-Light to offer lumen outputs between 2800lm and 12,000lm. Each recessed luminaire head is also capable of pivoting and rotating to direct the lighting in the desired location. As most of the library’s items of furniture such as shelving, chairs, and desks can be moved to

adjust to a new layout, the Gyro-Light can accommodate such future rearrangements, ensuring that light is always angled where it is most needed. LED technology has allowed this range to be offered with either Switch Dimming or DALI dimming function, whilst both LED and CDM-T variant can also be provided with 3000k or 4000k colour temperature to suit the application. Both the Gyro-Light and Modled Suspended were installed with Switch Dimming to allow staff to adjust the lighting according to their needs.

The Gyro-Light is suitable for pull-up installation and can be fitted quickly and cost-effectively by being delivered fully assembled and ready to install, and can be supplied with prewired leads of choice to facilitate installation further.

Stairwells & Circulation Areas – Discalo LED & Modled Curve

The Discalo LED offered a highly efficient, low-maintenance solution for the stairs leading up to the library, adding a modern decorative touch with its white halo effect (also available in blue). The luminaire is available in lumen outputs of 1500, 2000 and 3000 to match the performance of 28W 2D, 38W 2D or Circular T5 model
