The University of the West of England (UWE) in Bristol has recently quadrupled its solar generating 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 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 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 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 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% 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.”

British Airways i360 is the world’s tallest moving observation tower and first vertical cable car. At the entrance of the attraction on Brighton Seafront is an accessible roof terrace area that features over 1,500m2 of Bauder’s reinforced, inverted hot melt waterproofing system with hard landscaping.

The futuristic British Airways i360 is a 531 foot tall structure located at the landward end of Brighton’s historic former West Pier. Eleven years in the making, British Airways i360 is the brainchild of architect-entrepreneurs David Marks and Julia Barfield of Marks Barfield Architects, best known as the practice that conceived and designed the world-famous London Eye. Groups of up to 200 visitors will glide gently upwards to a height of 138 metres in a futuristic, fully enclosed, hand-crafted glass viewing pod to admire 360-degree views across Regency Brighton and Hove, the South Downs, the English Channel and the south coast east to Beachy Head.

Passengers board each flight via the alluring outside terrace deck, which features reconstructed tollbooths of the original iconic West Pier that now serve as a ticket office and café, where people can relax and socialise. Understandably this roof top area will experience significant amounts of foot traffic all throughout the year, so the client wanted to install a waterproofing system that was both robust and of the highest quality. Given these requirements, Bauder’s hot melt structural waterproofing system with hard landscaping was a natural choice. The system is designed to last the lifespan of the building and provides a monolithic, fully bonded membrane that is self-healing to minor punctures and ideal for use on protected roof areas. As part of the system approved contractor Accurate Roofing also installed inverted insulation, to deliver high thermal performance in exposed conditions and help retain heat within the beachfront building below that houses a brasserie, café and gift shop.

This new landmark is an exceptional example of how modern architecture and roof landscaping can revive a historical monument, which is expertly and intricately intertwined with over 150 years of history. British Airways i360 has already attracted significant interest and proven extremely popular, welcoming its 100,000th visitor just three weeks after it was opened to the general public in August 2016. The attraction was given a Royal opening by His Royal Highness the Duke of Edinburgh in October.

There is growing demand for improved safety within the education sector, especially in relation to refurbishing school and academy buildings. In response, flat roof manufacturer Bauder has developed various high-performance waterproofing solutions over the years that can be installed using flame-free methods; removing the need for a naked flame or hot bitumen at roof top or ground level.

The Construction (Design and Management) Regulations 2015 place specific duties on designers, contractors and building owners to take fire safety into account throughout a building’s life cycle, making sure that all people on site are protected if a fire does ever occur. By utilising flame-free roofing solutions it not only eliminates any risk of fire from hot works but also means that school buildings can remain fully operational throughout, causing minimal disruption to the school term.

Bauder has a comprehensive system portfolio that includes a choice of bituminous, cold liquid applied and single ply waterproofing solutions, which all deliver a safe, flame-free alternative to traditional application techniques without compromising on quality, performance or aesthetics.

Bituminous solutions

Bauder’s bituminous system Airtech has been specifically developed to meet the need for improved safety, combining the latest generation of heat activated self-adhesives, polyurethane adhesives and hot air welding for an unrivalled flame-free installation that is faster, cleaner, quieter and safer than traditional pour and roll or torch-applied methods.

The single layer elastomeric bituminous membrane features patented lap joint technology that is sealed using electrically driven hot air welding equipment, which can be powered from the mains supply or by generator where appropriate. This process is simple but precise and avoids operatives having to carry buckets of hot bitumen on site and having unattended pot boilers at ground level, removing risk to school staff, students and visitors alike.

The system has an estimated life expectancy in excess of 30 years, can easily withstand foot traffic and permanent loads and features elastomeric detailing membranes that make them practical for full bond application even during cold conditions. The membrane also includes expandable graphite fire retardant to prevent the spread of flame in the event of a fire ever breaking out.

Cold liquid applied solutions

Bauder’s cold liquid applied systems, LiquiTEC, are based on the most advanced PMMA (Poly Methyl Methacrylate) resin technology, combining ease of application, exceptionally fast cure and durability without using any hot works, making them suitable for use in all kinds of flat roof, balcony, walkway and terrace waterproofing applications.

All Bauder LiquiTEC products are solvent, isocyanate and halogen free; and unlike many other systems do not contain styrene and isocyanate, which are linked to serious health risks. The waterproofing products are resistant to ponding water and also incorporate a polyester fleece to provide increased membrane strength, life expectancy and resilience to cracking.

The fast curing times and cold application make this an ideal solution for refurbishing school buildings; as it causes minimal site disruption, the roof area can be accessed within hours of installation and it delivers a UV stable, seamless waterproof membrane of the highest quality.

Single ply solutions

Bauder’s single ply waterproofing systems, Thermofol (PVC) and Thermoplan (FPO), offer a lightweight, fast track, flame-free installation suitable for new build or refurbishment projects. The systems are installed using hot air welding techniques with mechanical fastenings or adhesive bonding to provide high-performance solutions, which are durable and give excellent fire resistance.

The membranes deliver strong and flexible polymeric waterproofing that is resistant to weathering, chemical oxidisation and UV radiation. They not only possess exceptional performance characteristics but are also incredibly versatile to meet the specific design challenges of each individual project.

Flat roof manufacturer Bauder launched its revolutionary solar PV mounting system for biodiverse or extensive green roofs, Bauder BioSOLAR, at the inaugural ‘European Biosolar Roof Conference’ that took place in September at City Hall in London. Designed primarily for new build applications where environmentally friendly solutions are required to meet planning and BREEAM requirements; this integrated system addresses the misconception that green roof and PV technologies are mutually exclusive options.

The construction industry has long been calling for rooftop solutions that include a duality of technologies for environmental advantage, and a biosolar roof delivers just that providing reciprocal benefits in terms of maximising the energy output from the PV module and the footprint for the green roof. Bauder’s innovative BioSOLAR system uses the substrate and vegetation to provide the ballasted installation mechanism, removing the need to penetrate the waterproofing to secure the mounting units to the roof and making the most of the available area for vegetation, enabling the entire roof to qualify as a biodiverse green roof.

A key feature of Bauder’s unique system is that the front edge of the polycrystalline PV panel is raised 300mm above the finished green roof level, allowing light and moisture to reach beneath the panels whilst ensuring the mature vegetation will not shade the panels and can be easily maintained. The mixture of sunny, shaded and sheltered areas together with a variable depth of FLL compliant extensive substrate gives a matrix of different habitats that allow a broader range of plant species to thrive, and a rich foraging environment for bees and insects.
The biosolar solution also delivers advantages to the building, as the cooling effect of the vegetation and water held within the green roof system preserves the ambient temperature around the PV array, which in turn increases the solar output by over 5%. The PV mounting frame features a 100% recycled high-density polyethylene base board and consists of just three components – a quick fix angle support, profile module rail and module fixings – that make for an extremely quick and simple installation process.
Although well suited to new build applications, the Bauder BioSOLAR system can also be retrofitted on many existing roofs without the need for any structural modification to the building; and with Bauder able to supply and install all of the waterproofing, green roof and PV elements you can be confident of the significant synergy effects created by this energy efficient and cohesive system.

The library roof at the Queen Mary University of London (QMUL) had surpassed its natural life expectancy and been experiencing considerable water ingress, requiring urgent remedial work to prevent disruption to students.
In order to determine the most appropriate remedial solution the 2,000m2 roof area was surveyed by flat roof specialists Bauder, who proposed stripping the existing roof covering down to the structural metal deck and replacing it with a high quality and long lasting bituminous system. The client also decided to use this opportunity to make a positive and visible contribution to the university’s carbon reduction programme through the addition of energy producing solar panels. The library is the core study area for most students and is unsurprisingly one of the highest consumers of electricity out of all the campus buildings, so it seemed extremely appropriate that the PV would be situated there.
The main library roof and three connecting tank rooms were all waterproofed with Bauder’s premium bituminous system, BTRS, which is capable of withstanding permanently sited loads of up to 2000Kg/m2 and has a life expectancy in excess of 40 years. The system build-up included a highly efficient 120mm PIR FA-TE insulation for superior thermal performance, achieving the required 0.18 U-value. Tapered insulation was also used around the perimeter of one of the tank room roofs to effectively provide drainage falls without having to incorporate them into the structure.
Roof areas totalling 1,000m² were fitted with 126 monocrystalline PV modules, set at a 10 degree angle to optimise energy generation. The panels are expected to generate 32.43 MWh of energy within the first year and deliver CO2 savings of 17.155 tonnes, equal to 8,358 kg of coal burned. The PV system was installed using a unique drill-free technique that ensures the integrity of the roof is completely upheld; and the simplicity of this method also meant that roofing contractor, R T Roofing Services, could install the entire array in just two days.
One of the major challenges for this project was performing the required works on a busy campus and keeping noise levels to a minimum. To overcome this challenge the project team worked closely with the client to develop a work and delivery schedule; with many of the materials brought to site and unloaded at the weekend. Bauder also provided ear plugs for all library users to make sure that they weren’t disturbed from their work. Despite these logistical challenges, all roofing works were completed in time for the start of the new academic year and were undertaken as part of the university’s long term maintenance and regeneration programme.
Jennifer Raagas, QMUL Project Manager, stated her delight with the finished works at the university, “We are incredibly pleased with the work performed by Bauder and their approved contractors on the library roof. They have been extremely accommodating during an eventful summer period at the university, and their service has been of the absolute highest quality. Our new BauderSOLAR PV panels will not only help us generate our own solar energy but will also provide excellent research and learning opportunities for our students. With Bauder delivering a single source solution of roof renewal with PV install we have complete peace of mind over our roof’s guarantee and long-term future performance.”

Morris Blitz Court is a residential housing estate located in Hackney that has recently undergone an extensive amount of refurbishment works as part of the Decent Homes Programme. Included within the approved scheme was the refurbishment of all of the building’s balconies and walkways, as well as the transformation of the 1,000m2 concrete podium deck located above the car park into an aesthetically pleasing social space.

Prior to any work commencing on site, Hackney Council hosted regular consultation meetings with all Morris Blitz residents where plans were presented and discussed. Upon receiving approval for the proposed refurbishment works the building was surveyed by flat roofing specialists Bauder to investigate the options available for improving the aesthetics and functionality of the podium deck, and to determine what course of action needed to be taken to ensure the building was watertight. The client’s main priority for the podium deck was for it to be totally free draining so that there was no standing water, which had previously caused problems. Various waterproofing system options were explored, however it was decided that Bauder’s cold liquid applied systems would be the most suitable solution given all the requirements.

One of the major challenges for this project was the low door thresholds connecting to the podium deck, which couldn’t be raised, meaning that the entire build-up for the majority of the cold liquid waterproofing and landscaping elements would need to be less than 100mm in height. Because of these restrictions the only drainage and protection board suitable within the system was Bauder’s Versicell 20, which is just 20mm in height but can withstand extremely high loading. The LiquiTEC system also incorporated 140mm of Bauder’s JFRI insulation in sunken areas of the podium, ensuring a level surface across the deck and combining thermal efficiency with environmental friendliness. The surface of the deck consists of three distinct finishes; permeable paving on the ground floor patios and walkways, artificial turf featuring fibreglass planters to serve as a communal garden and rubber mulch to create a play area for children.

The cantilever style balconies and communal walkways were waterproofed with Bauder’s LiquiBALKON system; demanding a high degree of workmanship from Bauder approved contractor Armour Group due to the amount of intricate detailing requirements. This waterproofing system features PMMA resin technology that provides exceptionally fast curing times and can in fact withstand foot traffic within an hour of being installed. This was essential as the residents of Morris Blitz remained in situ throughout the installation and working hours had to be scheduled between 10am and 2pm to accommodate for school hours. Despite the various design, technical and installation challenges encountered all waterproofing and landscape works were completed on time and to budget much to the delight of all project stakeholders.

Harsha Amin, Project Manager from Hackney Homes, stated “The required refurbishment works at Morris Blitz Court were by no means straight forward. However Bauder were able to deliver a comprehensive, single source waterproofing solution of the absolute highest quality; providing expert technical support throughout the project and demonstrating exceptional levels of workmanship. They caused minimal disruption to residents and have successfully transformed this housing estate in terms of appearance and functionality; creating a visually appealing and inviting communal space where residents of all ages can relax and socialise.”
