Creating a Vibrant and Attractive Office Environment, Including the Roof!

Iko Ireland

A detailed visual and physical inspection, together with core and moisture probe analysis carried out by IKO on the roof, patio and walkway areas, indicated that the waterproofing membrane was in a condition commensurate with the age and the type of the traditional membranes installed. They had become fragile and brittle. The decks were saturated due to water ingress, and natural ageing had played a principle part in the deterioration of the waterproofing system. The build-up would not have met the requirements of the current building regulations Part L. IKO worked to refine the specification for the main roof,

Replacing an Original 1949 Roofing Waterproofing System Including New Rooflights

Replacing an Original 1949 Roofing Waterproofing System Including New Rooflights

Iko Ireland

Perry Hall Academy, a large primary school built in 1949, with original waterproofing still in-situ. IKO assisted the Academy funding bid by providing a detailed survey report, including intrusive core sample analysis. The roofs were suffering from water ingress, cracks in the mastic asphalt, pooled water and poor heat retention, so decision was made to replace the roofs throughout. New rooflights were also specified to allow more natural light in while the design chosen reduced the external noise transmission. IKO worked with specifier Concept Education Services to deliver the project (some work during term-time) within 6 months.

Standard Coniston Wall Mounted Canopies: 8m x 2.1m and 8.9m x 2.1mCanopy Frame Colour: Light Blue RAL 5012, matt finishInstallation Date: August - September 2019Contractor: Morgan SindallArchitect: Miller Bourne ArchitectsThe BriefIn September 2018, an invitation to tender was received by Able Canopies from Morgan Sindall Construction Ltd for a number of canopies at the brand new two-storey, primary and nursery school for which they had been awarded the contract to build to form part of the Hailsham Community College Academy Trust.After reviewing the tender documents we put our recommended products forward, which was a large Kensington wall mounted canopy and two Coniston wall mounted canopies.The architect then contacted us directly to detail that the main building frame was made up of large timber SIPS panels and the large steel posts were required to support the roof. However, they were also decorative in essence and played a significant part in the building aesthetic appeal, and they required Able Canopies to supply and install them as part of the package as they would run through the larger canopy.The original design and price we submitted did not require the inclusion of the steel posts, however we were then asked to include in our canpy costs. We therefore went back to the drawing board to come up with a canopy design which would fit the aesthetic and structural features required.The SolutionWhilst in talks with the architect, they explained that they favoured our Coniston Wall Mounted Canopy system and also requested the NBS spec for the product which wasn’t a problem as our products are all listed on the NBS National BIM Library.We therefore looked at the Coniston system and worked with the structural engineer to ensure the steel beams could be incorporated into the canopy. This enabled us to supply the contractor and architect with an estimate so we could secure the works as an early package enabling them to cast the foundations required within the main slab.Because the bespoke Coniston would have the required large steel beams through the roof, we designed a solution to ensure the canopy would still be a fully waterproof system. This was easily achieved with the Coniston because we were able to comfortably flash/dress around the roof support columns, to create a seamless walkway with a watertight roof.However, the large steel beams and underside required a lot of design work, we diligently designed bespoke connections for the posts to the beams, bespoke connections for the roof bar to the steel beams and bespoke guttering & gutter connections. This replaced the Coniston’s standard integral guttering system with an external gutter system that worked with the design perfectly.Click the link to continue reading..... https://www.ablecanopies.co.uk/c/wall-mounted-canopy-case-studies/hailsham-community-college-primary-academy-case-study.html

Welsh Slate helps Attleys catch a curve ball at Coal Drops Yard

Welsh Slate helps Attleys catch a curve ball at Coal Drops Yard

Welsh Slate

Some 92,000 Cwt Y Bugail slates feature on a ground-breaking new/old roof. Formerly a seedy area worth avoiding, London’s Kings Cross has now been transformed into a go-to destination for office workers, students and tourists. Developer Argent’s regeneration of the area has sensitively re-purposed the early Victorian railway buildings into variously, a college campus, supermarket and offices, in which the interior changes are radical but the exteriors have been left largely unaltered. Not so for Coal Drops Yard, a pair of elongated Victorian coal warehouses originally built to distribute coal from the North of England across London. Here, the pitched roofs of two almost-parallel buildings, 150m and 100m in length and 39m apart, have been reconfigured to curve up at their northern ends and gently kiss each other. Designed by Heatherwick Studio, the roofs peel upwards and extend into the middle of the space between the two buildings. A new floorplate sits below the roof structure, with glazing filling the gap between the two, creating a third level of retail. The new roofs of the ornate cast-iron and brick structures have been slated with 92,000 new versions of the original Welsh Slates – 500mm x 250mm Cwt Y Bugails from the manufacturer’s Llan Ffestiniog quarry in North Wales – by Banbury-based specialist sub-contractor Attleys Roofing. Attleys already had some Kings Cross experience, using 6,400 500mm x 300mm Heather Blues from Welsh Slate’s main Penrhyn quarry for the re-roof of the nearby German Gymnasium - the first purpose-built gym in England - which is now enjoying a new lease of life as a designer restaurant. Coal Drops Yard was a whole new ball game, testing Attleys to the limit, but the result is an extraordinary reinterpretation of the canal-side site. Main contractor BAM Construction was responsible for the structure of the new roofline. More than 50 new steel columns were carefully threaded through the existing structure to support the roof independently of the building, a point cloud survey being carried out to help calculate where to put the columns without clashing with the existing building fabric. Primary support is provided by a set of large cranked beams supported on cores in each building which join in the middle over the yard. There are four primary beams, two on each building. These dip down towards the centre to create the valley between the two roof structures and have been nicknamed “giraffe beams” in reference to their angled neck and head - the structure looks like two giraffes rubbing noses together. Tie beams at floor level take the tensile loads generated by the weight of the roof. The giraffe beams support two ribbon trusses that define the upper and lower edge of each roof structure and connect in the middle over the yard at the lower edge. These are 7m deep in the middle and taper to 5m at the ends where these join the existing roof. Tubular steel sections were used to create the trusses because of the complex geometry. The new floorplate below the roof is suspended from above using macalloy bars and is tapered towards the perimeter to minimise the impact on the view. More than 60 panels of full-height structural glazing between the floor and new roof are stepped rather than curved or faceted for aesthetic reasons and has the added benefit of hiding the macalloy bars. Temporary trusses were erected to support the giraffe beam assembly and ribbon trusses during construction. The giraffe beam assembly was erected first. The ribbon trusses were brought to site as components, bolted together on the ground into fully-assembled sections complete with rafters, craned into position and bolted together where they meet in the middle. The whole roof structure was then de-propped. Visually, it was important to maintain a seamless transition from the existing roof to the new section so the original timber roof trusses were retained where possible, with some localised strengthening required where the timber had been damaged. The gap between the existing and new roof structure was then boarded over ready for the new Welsh slates.The two roofs are bolted together where they meet in the middle. Heatherwick Studio chose to position the new roof element at the northern ends of the two buildings as the eastern building had been devastated by a fire in 1985. Used more recently for warehousing and nightclubs, they were largely abandoned in the 1990s. Group leader Lisa Finlay said: “Our challenge was to radically remodel this Victorian infrastructure to meet the needs of a modern urban development without losing what made them special. To do this, we focused on understanding their original function and how they were adapted over time so we could appreciate how best to preserve and reuse the existing fabric, whilst also introducing new elements. One of which is an entirely free-standing new structure threaded through the historic buildings, from which a spectacular new third level is suspended.”  Attleys were on site for a total of almost 18 months. The roof pitch of the original sections of roof was 28° but as the curves swept around and met in the middle this changed to 47°. Thereafter the length also decreased from 8.4m to 6.9m at the kissing point where the two curved roofs met but the same number of courses of slates (44) had to be maintained. This meant Attleys had to decrease the gauges and not only cut the sides of the slates to take them around the curve but also the tops of the slates to maintain the same number of courses. No clever nailing or hidden bibbing was required to stop rainwater flowing diagonally at this point as the pitch was so steep. Attleys’ managing director Shaun Attley met with Heatherwick Studio and BAM’s design team up to two years prior to commencement on site to discuss the design issues and how to achieve the aesthetics requested while using the products selected.  Shaun advised the project team that the Cwt Y Bugail slates could not be used for their initial roof design which exceeded a 90° pitch so it was re-designed to ensure that where the eaves met it was at a pitch commensurate with Welsh Slate’s fixing recommendations and warranties. Due to space being at a premium, all the Cwt Y Bugail slates were cut off-site at Attleys’ depot in Banbury. To do this, Attleys had to calculate how much of the slates needed cutting off. This was done by taking measurements from the steel work underneath - from steel to steel at the eaves and steel to steel at the ridge which was generally over 10-15m depending where you were on the curve (on the internal curve or external curve). The kissing point determined how the slates were cut to ensure the perp lines and side laps were maintained.  And because the roof pitch was increasing while the rafter length was decreasing, Attleys also had to cut the tops of the slates down so they suited the decreasing gauges. A total of 32,000 of the 90,000 slates used on the project had to be cut with hand guillotines so the dressed edge could be maintained around the curve which comprised 1,600m2 of the total 4,600m2. Shaun Attley said: “Our timescale for the sections of roof was provided to BAM Construction and this was put into their overall programme with all other sub-contractors but unfortunately our commencement on site was delayed due to previous issues in the construction of the steel frame prior to us starting.  “This meant we were up against the clock in trying to pull back time to ensure the overall programme was still met and we were asked by BAM to find ways of doing as much as possible off-site and increasing labour and production on-site to pull back the time lost. By working together with other sub-contractors and the main contractor we managed to finish a week earlier than our anticipated 43-week overall programme.” He added: “The project was challenging at the beginning to ensure we set the roof out properly but as the contract progressed it became easier. Welsh slates are easy to work, and we work with them all the time, but in this case it was challenging getting the slates to course all the way round. Attleys’ SMSTS-trained supervisor ran the day-to-day safety, conducting Toolbox talks every morning and attending daily safety briefings by BAM Construction staff and supervisors from all trades on site to brief each other of any risks and ensure trades were not disrupting one another.  The team of 10 Attleys operatives, which included two NVQ Level 2 apprentices, carried out daily visual inspections of tools and all power tools were PAT tested every three months. Shaun Attley visited weekly to inspect the job for workmanship and production and also to gather feedback on any safety issues or to see if any safety measures could be instigated to improve the overall safety for their and other operatives on site. “We found some of these measures not only improved safety but also helped improve production,” said Shaun. Attleys also had an independent safety inspector (from The Health & Safety People) visit site monthly to see if there were any safety improvements they could recommend. Far from handling eight million tonnes of coal a year, Coal Drops Yard is now forecast to pull in 12 million visitors a year.

Britmet Lightweight Roofing: LiteSlate Residential Roof Renovation

Britmet Lightweight Roofing

This case study focuses on the successful implementation of Britmet's Structural Conversion System, BritFrame, and composite slate tile, Liteslate, installed by ART Contracts LTD in a residential flat roof renovation project near Llangollen. The existing roof had been plagued by ponding and water ingress, necessitating repeated repairs and replacements over 20 years. This case study explores the benefits, challenges, and outcomes of utilizing the Britframe and Liteslate, providing a long-lasting and aesthetically pleasing solution. Residential flat roofs are susceptible to issues such as ponding water, water ingress and yearly inspections, which can lead to recurrent maintenance and repair requirements. This case study showcases the utilisation of Britmet Lightweight Roofing's Britframe Structural Conversion System and Liteslate to overcome these challenges and deliver a durable, low-maintenance roofing solution. Britframe is a versatile and innovative solution designed to convert flat roofs into pitched roofs, providing improved water runoff and a new more aesthetically pleasing finish, and reduced risk of ponding water and improved thermal performance. This can be covered using a variety of different roofing materials, and Liteslate, a lightweight synthetic slate roofing slate, was specified due to its excellent weather resistance, durability, and aesthetically appealing finish. Llangollen is part of the UNESCO World Heritage Site along eleven miles of canal from Gledrid to the Horseshoe Falls and required a durable yet authentic roofing solution.The project involved the renovation of a residential flat roof that had undergone multiple repairs and replacements over 20 years due to ponding and water ingress, and constant maintenance. ART Contracts LTD was tasked with implementing and installing LiteSlate to resolve recurring issues.The Britframe System converted the existing flat roof into a pitched roof, enabling efficient water runoff and preventing ponding, thereby eliminating the risk of water ingress, and reducing the need for yearly inspections and constant maintenance to site, Britmet’s Liteslate offered excellent weather resistance and durability, reducing the need for frequent repairs and replacements while offering an attractive finish replicating the appearance of natural slate. Overall offering the advantages of lightweight construction and ease of installation.Conducting a thorough structural assessment of the existing flat roof to ensure compatibility and feasibility of the Britframe required careful analysis and engineering expertise. Coordinating the installation of the Britframe and Liteslate with existing roof features, such as skylights or ventilation systems, posed challenges in achieving a seamless integration.The implementation of Britframe has effectively addressed the issue of ponding, providing efficient water runoff and preventing water ingress into the residential property. The utilisation of Liteslate offered exceptional durability, weather resistance, and longevity, significantly reducing the need for future repairs and replacements, and thereby providing long-term cost savings. Liteslate also improved the overall aesthetic appeal of the residential property, replicating the natural beauty of slate roofing while offering the advantages of lightweight construction. The integration of the Britmet Lightweight Britframe System and Liteslate successfully addressed the challenges the building was facing. The project resulted in improved water runoff, enhanced durability, a more aesthetically pleasing roofing solution, along with a new 60+ year life expectancy. This case study emphasizes the importance of selecting innovative and reliable roofing systems to overcome recurring roofing issues and deliver long-lasting and visually appealing outcomes.

Golden Side Return Extension, Including Opening Vario Rooflight.

Golden Side Return Extension, Including Opening Vario Rooflight.

VELUX Company Ltd

Jessica's home renovation and extension. Please see below a brief overview of Jessica's renovation journey in a blogpost:I’m not going to lie, renovating in a pandemic with no kitchen, was extremely stressful at times, particularly during the long stretches we were home-schooling, and it’s not something I’d want to repeat, but it definitely could have been worse, and we survived it.We bought this house six years ago and I have wanted to do the kitchen side return extension ever since Day One, but we had to wait and save, and then finally in September last year (2020) the day finally came, and we started the renovation. For reference, this is what it looked like when we bought the house. We did do a budget makeover in the interim by painting the cabinets and replacing the handles, but by the time we came to do the major building work we had doors hanging off, shelves collapsing, and the major lack of storage meant things were stuffed in and precariously balanced on top of each other and ready to topple as soon as anyone dared to delve in. I shared lots of my inspiration and ideas for the new kitchen before we started. I knew from very early on that I didn’t want to spend a huge amount of our budget on creating a fancy architectural kitchen extension. For me, the space inside was what was most important, and I just wanted to make sure we were maximising that to its full potential. We hired architect to draw up just the plans for us. I had initially wanted a pitched glass roof to run the length of the side return extension, but council planning regs and the unusual way our house is laid out, put paid to that idea. Our local council had recently introduced a height restriction of 2.5m at the boundary when extending more than 3m at the rear. Which we weren’t. Or so we thought! What we hadn’t realised is that the existing kitchen had already been extended and that counted towards the allowance, so the restriction did apply. This caused a lot of stress at the time, as we were so worried that the ceilings were going to feel low and dark. The good news is that as soon as the Vario by VELUX rooflights went in, all our worries melted away, and it’s not something I even notice or think about now.Another thing we did was speak to our neighbours about a third-party wall agreement. This was pretty key for us, as the buttress was on our side of the wall and if we had to build around it we would have lost at least half a metre of the side return. What we needed to do was take it down and build up right up to the boundary (saving as many of the London stock bricks as we could in the process). Luckily our lovely neighbours agreed, as this really did make a huge difference to the internal space.The LayoutI have had a lot of questions about many different aspects of the kitchen, but I think the thing I have been asked about most is the dimensions and the layout. We extended out 1.5m at the rear and around 2.5/3m to the side, bringing us to a total of 5m wide x 8m long. I think our layout is fairly unusual for a kitchen, and it seems to have inspired lots of people to try and do the same in their own kitchen renovations. The good thing about waiting almost six years to renovate your kitchen is that you get plenty of time to mull over what your dream kitchen might look like. The Design  knew I wanted to go with a seamless sleek, understated design and let the other materials do the talking, so I settled on the Urban kitchen, with slab doors. I worked with a kitchen designer to fine tune the space, and that’s where it really comes into its own, because they think of all the details you wouldn’t necessarily think of, and they know exactly how much space you need to allow you to move around your kitchen comfortably. The area around the island and peninsula was a tricky one to get right, because we didn’t want to interrupt the flow too much, but having lived in it for the last few months, I can confirm the kitchen designer got it spot on. We also included a fluted glass cocktail cabinet in our kitchen design, which houses all our glasses and drinks bottles and sits on the dining/entertaining side of the kitchen.The Vario by VELUX rooflightsOur previous kitchen had very little natural light and as a result none of us ever wanted to spend any time in there. So getting as much natural light as possible was a major priority in this renovation. We planned for two large rectangular rooflights along the side return (as we knew we needed a steel in between) and a square one towards the rear. Once we got planning permission, I asked our architect to tell me the absolute maximum amount of glazing we were allowed, and then headed straight for the Vario by VELUX website to design bespoke rooflights to the exact size we needed, using every last bit of glazing we were allowed! The bespoke nature of Vario by VELUX means you can tailor your sizes exactly to your needs. Using the 3D configurator online, you can also choose the frame colour, the type of glazing, and whether you want them to open or not. We have two 2.3m x 1m Rectangular rooflights (one opens) and a 1m x 1m square rooflight. Our builders had never worked with them before and were really impressed by the ease of fitting. The moment they went in, was the moment we really start to get excited about the new space. Even with screed floors and bare brick walls in November, the light was incredible in there. Now it’s finished, one of my favourite things is to work in the kitchen and watch the light as it changes and moves throughout the day. Even watching the rain is epic.

Britmet Lightweight Roofing: Slate 2000 and BritFrame in Social Housing Case Study

Britmet Lightweight Roofing

This case study highlights the successful implementation of Britmet’s flat-to-pitch conversion system, BritFrame, and lightweight metal roof tile, Slate 2000. The project, carried out by Jennings Roofing encompassed a total area of 500 square meters and aimed to improve the infrastructure of the existing roof. This case study examines the benefits, challenges, and outcomes of utilising Slate 2000. This case study highlights the successful implementation of Britmet's Slate 2000 roofing system and Britframe structural solution in a social housing project. The client, a new customer of Britmet, discovered the systems at the UK Construction Week (UKCW) exhibition. Impressed by the innovative design and features, the client expressed interest in utilising Britframe for a flat-to-pitch conversion project in their social housing development. The client is a housing association responsible for managing and maintaining a portfolio of social housing properties. They were seeking an effective solution to address various issues with one of their buildings, including an ageing roof with multiple repairs, inadequate insulation, and inefficient rainwater management. The objective was to enhance the building's aesthetics, improve water tightness, increase energy efficiency, and minimize future maintenance requirements. The initial meeting between the client and Britmet took place at the UKCW exhibition, where the client became acquainted with Britframe, a lightweight and versatile structural solution. Intrigued by its potential, the client arranged for an on-site visit to further assess the feasibility of utilising the Britframe and Slate 2000 roofing system for their project.Slate 2000 is a durable and aesthetically pleasing lightweight roofing material that offers long-term performance and weather resistance. It's stylish design and robust properties make it an ideal choice for enhancing the visual appeal and durability of roofs and cladding. During the initial site visit, Britmet's team evaluated the existing roof condition, rainwater management system, and insulation levels. After careful assessment, they provided the client with a budget price estimate for the proposed project. The estimate included the cost of materials, labour, and necessary ancillary items. To streamline the project, the client signed a Project Assist agreement with Britmet. This allowed Britmet to obtain planning drawings and submit the necessary applications on behalf of the client. Additionally, Britmet provided structural calculations, design drawings, and rainwater calculations to ensure compliance with regulatory standards and best practices. The main objective of the project was to convert the existing flat roof to a pitched roof using Britframe and install Britmet's Slate 2000 roofing system. This conversion offered numerous advantages, including improved water tightness, increased insulation, and resolved rainwater management issues. Notably, the internal gutters, which had caused maintenance problems, were relocated externally as part of the new design.Beyond functionality, the new roofing system and structural solution significantly enhanced the building's aesthetic appeal. The modern design of Britframe, combined with the stylish appearance of Slate 2000, seamlessly integrated the property with its surroundings. The improved visual aesthetics added value to the social housing development. One of the key benefits of choosing Britmet's Slate 2000 and Britframe was the assurance of minimal maintenance requirements. Unlike the previous roof covering, which had undergone numerous repairs and reached the end of its life, the new system was designed to be durable and long-lasting. This eliminated the need for ongoing maintenance and reduced future costs for the housing association.Through the adoption of Britmet's Slate 2000 roofing system and Britframe structural solution, the social housing project achieved its objectives of enhanced aesthetics, improved water tightness, increased insulation, and efficient rainwater management. The collaboration between the client and Britmet, from the initial meeting at UKCW to the successful implementation of the project, demonstrated the value of innovative roofing and structural solutions in the social housing sector.

If there are any doubts about what Grade A office spacereally means, then think touchless entry, bike storerooms, lux changing facilities, an 8,000 sq. ft roofterrace, a 150-metre rooftop running track, 4 activity zones/terrace spaces and panoramic views.The project complements the sustainable regeneration programme along the Clyde Waterfront also,home to the new financial Northern European hub, firmly cementing the business district at the heart ofmodern Glasgow.GOALSThe architects at Sheppard Robson have made sure sustainability and lifecycle credentials remaincentral to the design specification. Occupants’ wellbeing has been carefully considered with a stunningpanoramic rooftop and 150m running track and general outdoor employee wellness facilities.A roofing solution was required to support the lifecycle of the building along with an excellentproduct reputation for this distinguished office space. Given the quality, longevity and environmentalconsiderations required from the roofing design, the insulation properties and warranty performancewere extremely important from the outset.CHALLENGESOur Technical department assisted the architectural and construction teams to resolve numerouscomplex design elements across the varied roof zones including running track, ballast walkways, greenzones, and pedestal zones, to determine the best roofing solution.Installation of the Davit Arm System for a building of this scale was especially important so personnel canbe safely suspended whilst working at height. This presented us with a unique challenge in providing aworkable solution that aligned with the sequence of works, whilst facilitating future routine inspection ofits base plates, and maintaining waterproof integrity without compression.Careful planning and detailing were required around roof penetrations to minimise aesthetical impact,and roof equipment was safely installed above the roof assembly.SOLUTIONThe construction comprises a composite concrete slab receiving our Hot Melt Hydrotech Waterproofing System. Offering a true lifecycle – Hydrotech high performance waterproofing, through its’ unique characteristics and installation process, now forms part of the building fabric. The result offers complete watertightness for the lifetime of the building.The building is also insulated to a high u-value target offering exceptional thermal performance and achieving a high kPa rating. This was essential to receive loadings from all components including overlying finishes, roof equipment and the end use for the building occupants.Key fire performance standards were achieved throughout including the lift overrun and lower roof terrace areas where the preferred solution was switched to our Derbigum sustainable warm roof system to maintain project performance targets.LIFECYCLE MANAGEMENTDesigned with BREEAM credentials and an EPC rating coming in at below 10 the careful focus on lifecycleconsiderations and the choice of materials throughout the building envelope is exemplary.Hydrotech hot melt is a high-performance solution containing 30% recycled content and zero productfailures in over 50 years, offering lifetime peace of mind, designed for the service life of the roof.PROJECT DATACompletion: Autumn 2022Building Type: Commercial OfficeProduct Application: Hydrotech & Derbigum waterproofing systemsCertification: BBA Approved, European Technical Approval & FM Global Class 1Architect: Sheppard RobsonMain Contractor: HFD Group

Museum of London - Visionary Roof

Museum of London - Visionary Roof

Bauder Ltd

Museum of London - Visionary RoofSynopsisThe Museum of London opened in 1976 on the historic London Wall and is a few minutes’ walk from St Paul’s Cathedral. A visionary approach to roofing had been adopted on a building that, will not only green as much of the exposed roofs as possible, but also provide a strong research aspect for future green roof projects. As with many buildings, the original roofs needed to be upgraded or replaced, at the same time as being brought up to date using environmental and sustainable solutions.Through the recommendation of waterproofing and green roof manufacturer Bauder Ltd, the Museum invited Dusty Gedge, one of the UK’s leading independent green roof consultants, to work directly with them to design 3500m² of varying habitats that encompassed the museum’s sustainable vision. and help in the provision of environments that would attract a range of wildlife, as well as being able to help the city adapt to climate change.Bauder Building BoardProject:Visionary roof, Muesum of LondonLocation:LondonProject type:RefurbishmentRoof size:9512m²Specifier:Museum of LondonRoofing contractor:Russell Trew LtdThe specificationAn independent consultant had previously carried out an energy model on the Museum of London buildings. When the museum inputted the green roof specification, it showed a potential energy saving of 10% per year, as well as a reduction on the future replacement costs of the heating and cooling plant. Some of the green roofs were funded through Drain London, a partnership project led by the Greater London Authority and funded by Defra. The project aims to better understand surface water flood risk across London, with a view to promote interventions (such as green roofs) to reduce surface water flooding. The museum has used the Bauder green roof system and worked closely with Dan Costen of Bauder and the roofing contractor Russell Trew Ltd, to deliver the various green roof spaces.These include:The refurbishment of the lower garden in the central courtyard with hard landscapingThe installation of Bauder’s new wildflower blanket to the upper garden in the central courtyard (funded through Drain London)Plug planting the roofs of the recently completed garden and terrace rooms that provide high quality corporate hire (matching the colour scheme chosen for the rotunda garden refurbishment and integrated with the new rainwater harvesting system funded by Renaissance London)An integrated sustainable urban drainage system (SuDS)Plug planting in other individual small roof areas including outside the boardroom and committee roomsTwo different planting schemes on an area of the main museum roof where the Drain London Project aims to carry out water attenuation researchThe resultRetrofitting green roofs will help to realise the Mayor of London’s ambition, to increase green cover in central London by 5% by 2030. The Museum of London is one of the largest retrofit green roof projects in the City and is certainly to be commended for allowing its roofs to be used for research purposes. Not only will it provide a benchmark for best practice, but it also demonstrates that retrofitting green roofs onto existing buildings is both environmentally and economically viable and is the way forward in helping London adapt to climate change.System installedBauderflex Green 1 BauderPLANT E 42A torch applied SBS elastomeric bitumen capping sheet.

In this case as the museum building had already been energy modelled by outside consultants, it was decided to input the green roof specification into the model. The results showed a potential energy saving of 10% per year, as well as a reduction in future replacement costs for heating and cooling plant. These factors, combined with the longer life cycle replacement of green roofs compared with normal felt roofing systems, enabled me to produce a robust business case for green roofs. With increasing energy prices the economic benefits of installing green roofs can only become more viable”Dusty Gedge added:“One of the major issues that London faces is flash floods during the summer, when sudden rainfall levels overwhelm the current drainage network. With the support of Drain London we will be researching the rainwater run-off for different green roofs. This will help us validate the kind of roofs and depth of substrates that will negate the costly effects that the sudden rainfall has on the infrastructure of the City.”
