The SSE Arena, Wembley has installed a new house lighng system in its 12,000 capacity auditorium that is set to lower costs, reduce emissions and open up the venue to potenal new avenues of revenue from major sporng events

SSE Enterprise Contracting, one of the largest contracting businesses in the UK was tasked with the install, which began in late 2018. The work included the removal of 99 x 1500W halogen lamps, with an hourly power use of 148kW, which only gave 300 maximum LUX across the auditorium floor. Once removed, the entire system was updated with 60 new LED lamp units. The new units can provide up to 1500LUX across the auditorium floor and have a maximum power rating of 964W. This means that the auditorium can be lit to the same level as previously with halogen lamps, using just five per cent of the available power. This will lead to an estimated £80,000 saving per year in energy costs and maintenance requirements. Peter Fewings, technical and building services director, The SSE Arena, Wembley, says: “We’re very happy with the install of the new lighting rig at The SSE Arena, Wembley. Not only are we saving in energy costs, but we can now also light the auditorium to a standard expected from major sporting events. We look forward to the new opportunities this system will open up to us as we continue to upgrade our lighting systems throughout the venue.” Peter Ryde, SSE Enterprise contracting marketing manager, adds: “At SSE Enterprise Contracting, we are collaborating with the industry’s leading technology companies to bring energy efficient innovation direct to our customers. This practice has ensured many organisations from local authorities to heavy industry to actively reduce their energy spend

and meet their challenging carbon targets through employing the latest, future proof technology to ensure their facilities operate smart, greener and more effectively.” Nulty strikes the right chord in King’s Cross

Nulty has completed the lighng scheme for the excing new global headquarters of a major record label, based in London’s King’s Cross

The brief was to create a functional yet fun lighting scheme, which aesthetically linked the HQ’s various spaces, whilst avoiding a rigid corporate feel across the imposing new-build’s ten storeys of working space. The creative nature of the client’s business means their spaces have a tendency to switch purposes, with employees customising the layout of their furniture and even the rooms. Therefore, the lighting scheme needed to accommodate the ever- changing requirements of the building’s users. Nulty worked closely with BW contractors to realise McFarlane Architect’s concept of a consistent design style throughout, while also integrating a sense of controlled irregularity reflecting the client’s innovative values. Centrally located breakout areas are on every floor, surrounded by a ring of open plan desk spaces. All the ceilings are exposed concrete, and in the breakout areas there are feature timber slatted ceilings. In the more secluded collaboration areas randomly shaped, large-scale angular cork tiles hang from the ceiling.

Nulty integrated LED luminaires within the feature ceilings, and low glare pendants in the banquette areas giving these spaces a home-from-home, relaxed feel. Amongst the timber-slatted ceilings, in the additional breakout areas Nulty devised a series of seemingly randomised linear LED luminaires that echo the ceiling pattern and create visual interest. The linear luminaires continue into the private office and meeting spaces and are recessed within the ceiling tile system to create a flush finish. Carefully placed spotlighting is also used in these areas to pick up and highlight artwork and a myriad of graphics and music memorabilia displayed on the walls. Suspended circular pendants are included in some of the spaces to soften and provide contrast to the highly angular shapes of the open plan spaces. In the open plan desk areas, Nulty designed 7000 metres’ worth of striking extruded luminaires, providing direct and indirect light (reflecting light from the ceiling). Staord launderee awash in cost savings

Rinnai has just completed the installaon of two HDC1500i connuous fiow hot water heang units at a busy laundree serving businesses and the public in Staord

Rinnai was chosen on the recommendation of another laundrette owner, in Lancashire, who praised the efficiency and major cost savings because of switching to cascaded continuous flow hot water units as they guarantee almost unlimited supplies of hot water at peak demand whilst savings on fuel costs.

Word of mouth is the best possible marketing and a site survey was duly arranged and completed to confirm the best solution in controlling operational costs and efficiencies. The existing system was a heated stored water system, this meant that the site was paying to heat water it was not instantly using.

It was clear from the site survey that Rinnai units configured to maximise both space and energy efficiency, and critically, the system’s reliability, would yield seriously large cost savings to the owner.

Given that the Rinnai units were being wall mounted and externally flued, this gave extra storage space to the premises as there was no need for a dedicated plant room.

Comments Ray Gallimore, proprietor of the Weston Road Launderette, “The old storage system had become completely impractical, inefficient and needlessly expensive to run. “For example, the washers tend to be used sporadically. During a busy weekend there could be a demand for eight to ten people battling to use the machines at once, during the week there might be one or two. That meant we had to store a decent volume of hot water ‘just in case’ in the form of a storage water heater. Needless to say, keeping the stored volume at optimum temperature 24/7 was often wasted

energy, a really bad, expensive idea all round.”

Clearly the site needed to change the system to one that could cater for these fluctuations without running up huge energy bills and the solution wasn’t hard to find.

“I was made aware of Infinity water heaters installed in similar applications to mine and in general their experiences with their products and their personnel, such as the local Rinnai sales consultant, were consistently positive and professional. “The beauty of working with Rinnai is the service they offer. We presented the project to Rinnai’s technical sales team who came up with the design, configured the sizes of unit required and delivered the system complete and to a very tight timescale – this was key as the existing water heater had developed a leak and I was extremely mindful that the business had to remain operational to satisfy local demand. We are very happy with Rinnai and will be spreading the word,” adds Gallimore.

Now two HDC1500i internal mounted water heaters with secondary circulation provide hot water for 12 commercial machines, plus a sink and a wash hand basin.

“The Rinnai system has resulted in an energy reduction and gas saving due to higher efficiencies and because we are no longer maintaining large amounts of stored hot water. It’s not rocket science to work that out! “In terms of gas usage running costs compared to the old wasteful storage system, our bills have virtually been halved since the Rinnai system went live five months ago which is absolutely tremendous,” says Gallimore.
