that new developments seek to, where suitable, incorporate PV and green roofs into their designs, however not many are yet calling for biosolar technology, which is something that must change for this combined system to truly take off and become commonplace.
Future of biosolar
Designs that do not perform optimally for both technologies are often as a result of people assuming that the solar panels require more technical input then the green roof. Getting the green roof element wrong can mean the vegetation is forced to grow around the panels, which results in shadowing and therefore reduced energy generation. For many PV systems shadowing on one panel can subsequently have a detrimental impact on the overall performance of the entire string of modules. Switzerland, Germany and various other European countries
have already proven that when planned, designed and installed well, solar and green roofs can improve the performance of both elements. There are many local authorities in the UK requesting
Back in September, London’s Deputy Mayor for Environment and Energy, Matthew Pencharz opened the inaugural ‘European Biosolar Roof Conference’ at London City Hall. The event featured many expert speakers from across Europe, who are already successfully delivering biosolar technology, which gave architects, landscape architects, developers and suppliers invaluable insight on how to effectively implement and manage a biosolar roof project. The European Biosolar Roof training programme was also
launched at the event and will be delivered across Europe to support the delivery of biodiverse, energy resilient and climate adapted cities. The primary objective of the conference was to ensure that green roofs and solar roofs are no longer considered as an either-or option, but delivered together in perfect harmony; and if the initial feedback from the event is anything to go by, biosolar roofs look set to become an integral part of future building construction in major cities throughout the UK very soon.

TD MEGAPADS FROM WALLBARN
TD Megapads from Wallbarn are the best way to construct timber decking on podium decks, flat roofs, balconies, terraces and walkways.
The timber joists are placed onto the weight bearing pedestals, which can tolerate 800kg each. The joists are housed between the lug fittings for secure placement. A framework of timber joists is constructed and the decking boards fixed to the frame.
Unit 16 Capital Business Centre, 22 Carlton Road, South Croydon CR2 0BS
As all the timber is lifted off the surface, surface drainage is improved and slip hazards reduced. None of the timber is subject to standing water, improving its lifespan.
Address:
Installation is super-fast and straightforward. The plastic pedestals have large base plates which spread the weight evenly, avoiding point loading on the sub-deck.

Type S waterproofing membrane has helped to provide a watertight finish for a complex roof system featuring seven pyramids and a vaulted
rooflight. The entire roof build-up consisted of S-Vap 500E vapour control layer, insulation, tube fixings and Trocal S waterproofing membrane. Cold bridging was minimised with the use of the tube fixings to secure the insulation.

www.sikatrocal.co.uk Optimise efficiency in roof design
A bespoke software service allows designers and installers of flat roofing to optimise efficiency from design to installation. From basic data, Protan’s Proplan package will produce an autoCAD 2D or 3D visualisation of the proposed roof, detailed specification of materials,
the quotation plus manufacturing and site assembly details. The system embraces detailing such as corners, perimeters and penetrations, providing accurate estimating of the total roof cost, and allows comparison between systems. So the designer and contractor can obtain the most efficient way to build the roof, with optimum logistics, installation and virtually zero on-site wastage.
