Bauder delivers largest solar array in higher education sector


capacity through the installation of 1,731 solar panels, which will enable it to produce over 400 MWh of electricity each year and making it the largest solar panel array in the UK university sector. The new solar array has been installed on


T


the roof of the University Enterprise Zone (UEZ) and the Bristol Robotics Laboratory, which have both undergone extensive refurbishment as part of the required works. Prior to the solar panels being installed, approved contractor Mitie Tilley Roofing overlaid the original failing single ply waterproofing with over 12,000m2


of


Bauder’s lightweight, robust PVC single ply waterproofing system Thermofol. The solar modules, which weigh just 12Kg/m2


, were


then fitted onto the waterproofing using a unique penetration-free, welding method by renewable energy specialists Dulas. This


he University of the West of England (UWE) in Bristol has recently quadrupled its solar generating


sustainability and energy efficiency, and this solar project is just part of a much wider plan to achieve its carbon reduction goals and enhance local renewable energy capacity. Fabia Jeddere-Fisher, Energy Engineer at


installation technique means that the roof is not compromised by penetrations for fixings nor is it ballasted, which would add additional weight loading to the roof. The new photovoltaic system will generate


at least 74.32 Megawatt Hours of solar power each year which should; cover half of the energy consumed within the building, save around 200 tonnes of carbon and provide annual savings of over £50,000 a year. The university is highly committed to


UWE, stated, “From its conception, we chose a roofing system that would mean the flat roof would not need to be strengthened if we chose to add solar panels. Normally, panels placed on flat roofs require either weighing down or fixings that penetrate the roof membrane, which can introduce the risk of leaks. The system we have chosen means that the panels are welded into place, reducing load, and reducing the need for roof penetrations. The University will use 100 per cent of the power generated by the PV array, which will be equal to the amount generated by nearly 200 homes with solar panels. As a large organisation we want to set an example for others to undertake similar projects.”

Surface water channels efficiently drains aircraft hard-standing at Cork Airport


Beginning in June 2003 a €144.3 million investment in new 28,300m² facilities at Cork International Airport was completed in August 2006. The development included a new terminal and hard standing for parked aircraft. The hard standing area was drained by three sizes of Hauraton RECYFIX® HICAP®


high capacity channels – 150, 200


and 300. All the sizes had fixed ductile iron 28mm open slot inlets that comply with loading category Class F900. Having supplied high capacity surface


water drainage channels for aircraft hard-standing areas at both Gatwick and Heathrow, UK airports, Hauraton were confident their RECYFIX HICAP channels would comply with the stringent specification asked for by the Cork Airport design engineers. With aircraft tow trucks alone weighing 80


tonnes, manoeuvring aircraft impose an enormous burden on any surface drainage system. Not only must the area be efficiently

drained, the installed system must also withstand the twisting forces exerted by turning aircraft and numerous service trucks. During the construction stage, just


over 300 metres of RECYFIX HICAP were installed in the airport’s taxiways and hard-standing areas adjacent to the terminal building.


director, was pleased when his company’s high capacity channels were chosen for Cork Airport expansion scheme: “The HICAP channel components are made from specially formulated recycled polyethylene (PP), the heaviest one metre channel used, with the ductile iron inlet, weighed 25kg so allowed one-man-lift of the unit. This greatly simplified handling and logistics for merchant and contractor who found the combination of a tough PP channel and ductile iron slotted inlet resisted site damage during installation. The completion of this project means Cork ranks as one of the best regional airports in Ireland with its modern facilities and state of the art equipment. As with all Hauraton surface water drainage channels, the performance of the RECYFIX HICAP range complies with European Standards (hENs) and carries the CE mark”.
