Local Authorities in Redditch continue to lead by example through their sustainable renovation of Abbey Stadium. With Dextra Lighting’s precision-engineered LED solutions, the showpiece West Midlands facility has now reduced electricity consumption by 71% compared to the previous fluorescent system.
About the client
In 2015, Redditch Borough Council and five other local authorities in the West Midlands, formed a public sector asset management company known as “Place Partnership”. Sponsored by the Cabinet Office, the joint property venture applies a commercial business model to maximise the value of public estates. Through its “One Public Estate” programme, it aims to deliver real-estate solutions to increase operational efficiency in public buildings, promote regeneration and economic growth in the area, and ensure that taxpayers benefit as much as possible from each investment made. By targeting the energy consumption of its estate, the council and Place Partnership will help mitigate the impact of price increases on its services whilst investing the money saved into the improvement of other public buildings.
The council has recently focussed its efforts and resources on Abbey Stadium and Leisure Centre in Redditch, to ensure the building continues to be a hallmark of sustainable development. Completed in the 2012, the £6m facility attracted national attention for its unique design, which allowed the building to reclaim excess heat from the neighbouring crematorium to heat two competition-sized swimming pools. In 2011, the innovative project won the Green Apple Award which is presented to Britain’s greenest companies and organisations, and has secured its place in the Green Book as an example of environmental best practice. To continue to lead by example in the sustainable development and management of real estate, Redditch Borough Council recently invested in upgrading the leisure centre’s existing fluorescent to high-quality LED equivalents.
For the initial technical assessment with INECO energy, the Council’s Energy Consultants, Sports Centre Managers and Place Partnership representatives, Dextra Lighting presented a series of product samples to discuss a lighting design that would yield maximum return on investment and keep carbon emissions as low as possible. The meeting resulted in a solution that would comply with the councils invest to save funding model for the entire upgrade, with projected savings of a total of 71%; allowing the new system to be paid back in full over 5 years without interest or maintenance savings in the calculations. . Due to the long life and extended lumen maintenance of LED compared to HID or fluorescent lighting, these savings will avoid the council the ongoing expense of hiring external contractors to frequently change failed or rapidly depreciating lamps (particularly costly in high and hard to reach areas) to keep the installation running as intended.
In line with the environmental agenda of the parties involved, Dextra Group’s disposal and Recycling service led by Dexreco, was included in the proposal, to ensure all the old lighting fixtures were swiftly and conveniently removed according to WEEE regulations. Due to its vast and flexible manufacturing capabilities and dedicated transport fleet, Dextra Group was able to assist INECO Energy in completing the entire renovation project whilst the leisure centre remained operational exceeding expectations of quality and cost-effectiveness. By partnering with a reputable UK manufacturer, the project was delivered sustainably by minimising the carbon miles in the supply chain. Products were supplied and installed within less than 2 weeks from the approval of the order. All LED products supplied offered Dextra Group’s comprehensive 5-year warranty for extra support and peace of mind beyond installation.
INECO Energy’s “Designed for Efficiency” approach aims to deliver the optimum light levels using the least resource to deliver the greatest returns. The solution proposed delivered lighting levels which met with Sport England guidelines, reducing the number of fittings by 20% to deliver the best value to the client. LED alternatives were to be fitted in a number of locations including:
• 5-Court sports hall used for basketball, netball, badminton, volleyball, gymnastics, goal-ball and bowls.
• Two fitness suites: A free-weights room and a cardio fitness suite.
• Entrance and open-plan vending and seating area
• Changing rooms and WC facilities
• Storage and utility areas
Lighting design for sports facilities requires the appropriate task illumination levels for each sporting activity are met. Careful consideration is needed for the ongoing health and safety of the proposed solution to include, accessibility for maintenance, durability, integration with the building’s architecture and emergency lighting. Therefore the new system was to abide to British Standards, CIBSE and Sports England guidelines to provide the best lighting conditions for staff and customers alike.
Purpose-built LED luminaires with intelligent controls, were selected for the project, featuring the latest high-efficiency 3535 Lumileds LED sources and a wide range of optical designs and installation formats, to ensure lighting conditions were met whilst minimising energy usage and maintenance for years to come.
For added visual comfort and clarity, as well as overall consistency, all products were to be installed in a neutral 4000k colour temperature with colour rendering of over 80 throughout the premises.
Prosport LED – Sports Hall
High performance at low energy and maintenance costs for modern indoor sports environments
The Prosport LED is designed to make use of LED’s full potential to provide optimal light quality for a safer and more enjoyable player experience whilst ensuring minimal energy and maintenance costs.
By combining the latest Lumileds LEDs with a range of highly efficient optics, the luminaire offers a high light output ratio (LOR) of over 80% and a number of distributions to suit the sporting activity. From a range of three output packages of up to 30,601 luminaire lumens, the Prosport LED was supplied in both 15,079llm and 21,288llm versions to effectively replace the existing 4x55W fluorescent fittings; achieving the 300 to 750 lux level ratio recommended by Sports England for recreational and competition use. These versions offered energy savings of at least 30% compared to the previous T5 fittings, with an improved and longer lasting quality of light.
A symmetrical optic provided a versatile distribution ideal for the multi-purpose sports hall; complying to the correct uniformity ratios and glare control required for each sport. Asymmetrical brackets are also available with this range to obtain an angled, glare-free distribution ideal for badminton or tennis applications. With these options available, the Prosport LED was able to maximise visibility of fast moving objects in all areas of the field of play for a safe and stimulating player experience.
The Prosport offers flexibility at the point of installation, with suitability for trunking, surface mounting and suspension to adapt to a wide range of architectural requirements. In this instance, luminaires were rigidly suspended from the hall’s 9m ceiling to reduce damage from ball strikes, adapt to the existing trunking, as well as position the luminaires at the desired height for greater coverage. To cut the costs of installation, the Prosport was provided with a zintec spine to simplify mounting to trunking at high ceilings and was prewired to the required specifications.
Compared to the old T5 fluorescent tube fittings, the Prosport’s durable LED source eliminates the risk of shattered lamps dispersing into the field of play. Unlike rapidly depreciating HID and fluorescent lamps, these high-quality LM80-verified Lumileds LEDs also offer a 90% lumen maintenance at 60,000 operating hours which ensures that once installed, the luminaire will require little to no servicing to keep light levels as originally intended. With luminaires installed at such inconvenient heights, a sparing maintenance routine will save the council the time and money of technical labour and interruptions in service. The Prosport LED’s sturdy IK10-rated steel housing, polycarbonate end-caps and LED shield also ensure that the luminaire withstands the rigours typical sports environments on a daily basis in years to come.
With a choice of DALI (Digital Addressable Lighting Interface) or HFR (analogue 1 – 10v) dimming options, the luminaire can also be customised to offer flexibility to switch light levels for different sports and work in conjunction with a choice of sensors for further energy savings.
