CONTRACT NEWS THROUGH THE WIRE Wieland Electric has supplied its Metalynx2 structured wiring system to enable the channelling of power and lighting within the newly redeveloped Belmont in the centre of Uxbridge, West London. With the use of Wieland products, the project exceeds regulatory requirements in the provision of a sustainable and innovative solution, and it is anticipated that the CAT A office redevelopment will result in the building achieving a BREEAM ‘Excellent’ rating. Belmont has reached practical completion, following an 18 month, £30m redevelopment schedule of works, which saw the building stripped back to its frame and rebuilt to create a Grade A office scheme. Large, light filled, agile open plan floor plates – averaging 26,500ft 2 – have been created over five levels, designed to suit either a sole corporate occupier or operate as a multi-let development. Wieland’s Metalynx2 structured wiring system was specified by M&E contractor Phoenix ME to supply lighting and power to the office spaces, as well as lighting in the landlords’ core areas from the ground floor to the fourth floor.

Methane gas extracted from decaying waste at the site is used to generate electricity. The two 45kW VSDs efficiently control the speed of the motors running the gas compressor pumps, which were previously operated direct-on-line. Maintaining the correct gas pressure from the pumps allows more efficient operation. This means an extra 199,368kWh per year can now be exported back on to the grid, increasing revenue by £16,946. The solution uses two ABB general purpose drives to provide constant gas pressure to the generators. The VSDs use pressure transducers to feed back the gas pressure to the drives and allows them to control the speed of the motors to maintain the pressure at the correct level. Paterson’s Quarries’ landfill site at Mount Vernon near Glasgow covers 91 hectares divided into four zones, each operating independently to prevent the migration of gas and other materials. The site also includes a fenced gas management compound. This brings in gas from the zoned sections of the landfill site and burns it to produce heat to convert into electricity. The site produces 40,000MW of green electricity a year, enough to power up to 4,000 homes. This is sold by Patersons to Scottish Power Distribution, producing a significant income stream from the site.

The 3,000 acre Elmley estate is both a family-run farm with approximately 700 cattle grazing the pasture each year, and a special habitat for wildlife. The owners are passionate about nature conservation and have been managing the reserve for wildlife since 1974. As well as the spectacular wildlife and rare habitats, Elmley reserve also has a fascinating cultural heritage. Elmley National Nature Reserve is an inspirational place to visit just one hour from London. It’s a place that PowerGuard has had a close association with for three years, providing eco-friendly solutions to power remote buildings. Powerguard’s off-grid power generation systems have provided a bespoke self-sufficient solution to meet Elmley’s extremely delicate environment. Powerguard used an advanced technology system to ensure maximum efficiency and savings on fuel and maintenance costs. Taken from Powerguard’s standard PS System range, it is specifically designed to offer an effiient off-grid electricity supply. Providing increased performance, lower running cost, lower pollution output and a smoother more reliable power supply. Powerguard MD Graham Chapman commented, ‘We worked closely with Elmley to find a solution for their critical environment. Our PS Systems are designed to allow inputs from a renewable energy source, and we are proud to be associated with such a superb operation. Further benefits have been the ease of adding other power technologies such as solar and wind turbine systems.’ For further information visit: www.powerguard.co.uk TAXI! EVolt has completed the installation of three chargers to assist a Kirkcaldy based taxi business in achieving its environmental ambitions and support its five new private hire Nissan Leaf EVs, which are now fully operational. Taxi Central has installed one of eVolt’s Rapid Chargers, which can charge the 30kWh Nissan Leafs to 80 per cent battery life in 30 minutes, to provide on-shift EVs with essential charging capability and two eVolt AC 7kW wall mount chargers that fully charge the EVs in around five hours. The funding for the charge points came through the Energy Saving Trust (EST) and Transport Scotland, and eVolt achieved its status on the latest EST Scotland-wide charge point framework in 2016. Matthew Eastwood, head of transport – Scotland at EST, said EST is pleased to have provided grant funding on behalf of Transport Scotland to support this installation. He also commented, ‘By facilitating the introduction of EVs into the Taxi Central fleet, these charge points will help Kirkcaldy’s residents experience the benefits of EVs, reduce their exposure to harmful emissions and support the Scottish Government’s aim of decarbonising Scotland’s road transport.’ For further information visit: www.swarco.com 16 | March 2017
