Sheppard Robson’s third visit to Brunel is marked with Kawneer glazing systems. Aluminium glazing systems by leading UK manufacturer Kawneer were “fundamental” in achieving the environmental performance and architectural vision for Sheppard Robson’s second revisiting of a key building at Brunel University London. Kawneer’s AA®100 curtain wall, AA®540 vents, and series 190 and AA®720 doors were specified by the regular Kawneer users for the latest redevelopment of the Wilfred Brown Building at the university in Greater London. The mullion-drained capped and SSG (Structurally Silicone Glazed) curtain wall forms a new sawtooth façade to the first and second floors and is complemented by the AA®540 window vents which are top-hung and also Structurally Silicone Glazed, series 190 heavy-duty doors to the main entrance, and the thermally-superior AA®720 doors. Sheppard Robson had been working with Brunel since first master planning the campus in the early 1960s, designing the Wilfred Brown Building in 1968, and then adding a rooftop extension to the structure in the 1990s. This latest revisiting creates a new identity for the recently formed College of Engineering, Design and Physical Sciences and comprises the £13.8 million external and internal transformation of the 4,710m2 building to create a new gateway at the western boundary of the university. The primary driver in the development of the new Kawneer façade was the response to local environmental conditions – the west elevation employing the ‘sawtooth’ arrangement using clear glazed panels to the north west-facing elements, offering views out, and interstitial mesh to the west and south west-facing elements, to control solar gain. The building was originally designed to accommodate university administration facilities and as such was previously heavily cellularised, with a double row of central columns. It abuts, but previously did not engage with, the adjacent Michael Sterling building to the east and unsuccessfully linked to the adjacent double-height council chamber via a single-storey circulation link, previously cut off from the ground floor by a small courtyard space. Sheppard Robson Associate Neil Price said: “We specified Kawneer’s curtain wall as a simple and elegant response to renewing the Wilfred Brown Building. It forms most of the building envelope and the sawtooth façade arrangement to the west elevation in particular was key to achieving the architectural vision for the project. They were fundamental in achieving both the environmental performance and architectural vision for the project.” He added: “The glazed elements and their sawtooth arrangement to the west elevation are key to the architectural language of the Wilfred Brown Building, enabling the existing 1960s structure to be adapted and reused, whilst creating a distinct and modern identity for the scheme.” As part of the university’s Transformational Project (TxP) programme, and supported by the successful award of capital funding from the Higher Education Funding Council for England (HEFCE), Wilfred Brown has now been reinvented to create a new ‘front door’ for the college. Internally, the ground floor has been opened up and a new double-height atrium constructed to the north, infilling an existing, underused courtyard and connecting the buildings to create a STEM learning centre. This is a cutting-edge teaching facility aimed at engaging young learners through workshops with London schools. ‘INSPIRE – The Brunel STEM Learning Centre’ aims to engage learners from key stages one to five in science, technology, engineering, the arts, maths and medicine – areas in which the UK economy is forecast as having a future skills shortage. The programme is delivered through a series of unique STEM workshops that are research inspired, curriculum linked and industry relevant – an innovation hub comprising part of the suite of technology-led learning spaces. Three storeys of modern, open-plan academic workspace are housed on the upper floors to support progressive ways of working for students and 141 members of staff, ranging from academics and lecturers to heads of department. At third floor, a large open-plan PhD research office is provided alongside communal staff facilities. Formerly housing the university’s senior leadership team, department of estates and facilities management services, the Wilfred Brown Building has been reinvented as a modern, vibrant, student-focused teaching and learning facility. Key learning spaces for the Department of Computer Science are delivered across all levels in the building, including a 60-seat IT laboratory, a digital technology workshop and two technology-rich digital economy laboratories, which are connected via a retractable wall. Several research labs are distributed across the upper floors, while a dedicated cyber security laboratory is created at third floor in support of current research projects. Initial appraisal of the existing building, alongside interrogation of the university’s aspirations for the project, quickly established the need to replace the previous envelope with a modern façade system. Crucial to this decision was the need to significantly upgrade the performance of the external fabric, coupled with the aspiration to deliver a ‘world class’ gateway building, marking the establishment of a new college and the strategic objective to enhance provision of STEM outreach facilities. The facade strategy was conceived as an environmentally driven design response to the building’s orientation and its influence on the required performance of the façade. The completed facade achieves a significant improvement in performance through the enhanced thermal properties of the envelope, exceeding current air tightness requirements, improving the efficiency of the building services installation, and addressing solar energy transmittance through the installation of high performance glazing in response to site conditions. Alongside the wider sustainability strategy, enhancement of the envelope contributes to an improvement of 31.8% over Building Regulations Part L requirements, while the improvement over a baseline case representing the existing building is estimated to be 49.7%. Central to the viability of the project was the retention and alteration of the existing structural frame. Being marginally larger in plan, the façade extending a metre outwards of the existing footprint to the west, and with the addition of an extra storey at roof level, the structural capacity of the existing frame was maximised, the existing frame containing very little redundancy in its original configuration. Through thoughtful reuse of the existing building
Leading paving and building manufacturer AG has ramped up its production capacity by 50% following increased demand for facing brick and paving products from throughout the UK and Ireland. The family-run business has been at the leading edge of hard landscaping and building solutions for more than 60 years, providing world class products and services to architects, specifiers, contractors and homeowners across the UK and Ireland. The past 12 months has seen unprecedent challenges hit the construction industry with firms across the sector facing supply chain interruptions, increased lead times and significant skills shortages. CEO, Stephen Acheson said: Covid-19’s impact on our business was instant, but innovation and resourcefulness – two key components of our corporate DNA – have enabled us to not only survive but thrive. By continuing to invest in research and development and harnessing technology we have been able to embrace these new challenges by adopting new processes and capabilities throughout the business.” The third-generation family business has also created a number of new jobs across its manufacturing plants in response to the heightened demand across the domestic and commercial sectors. Acheson said “AG employs more than 230 people across eight locations meaning we were well placed to react quickly when the pandemic caused a nationwide shortage of building products, subsequently increasing lead times to unprecedented levels. In response, we introduced additional shift patterns into our plants as well as adding even more talent to our fantastic team, enabling us to increase stocks of Country Cobble, Facing Brick and paving products. “The past year has seen us achieve some record-breaking sales in both the domestic and commercial sectors which is testament to the resilience and outstanding work of our team”. Acheson said that the company expects demand for building products to continue to grow in the coming months: “We predict this exceptional demand will continue to grow over the next 12 months, placing considerable pressure on building merchants. In response, we have introduced new processes enabling us to significantly increase production input and massively reducing our lead times. We have greater stock levels of some of our most popular products which can be easily called off at short notice and lead times on some made to order items is as little as four weeks, which will be satisfying news to our customers.” AG – which has built a solid reputation for innovation – launched its ground-breaking Enduur advanced concrete technology earlier this year, a factory-installed enhancement process that improves the environmental performance of its products. It also launched its new revolutionary Fiamma range – a reconstituted flagstone resembling flamed granite – that the firm regards as its most advanced product ever. Stephen Acheson commented “2021 has been a big year for us and as we look towards the new year, we remain committed to delivering the best products to our customers”.
A prominent polymer system supplier is advocating the specification of more sustainable heating and cooling solutions in educational buildings following the publication of analysis suggesting most UK universities are not on track to hit emissions targets. The recent release of People and Planet’s annual University League asking ‘how sustainable is your university?’ found that despite 46% of higher education institutes making good progress in this area, the majority were still behind. Specifically, the analysis found that over half of the 154 institutions surveyed had failed to match criteria set out for 2020-21 by the Higher Education Funding Council for England in 2010. With these findings in mind, polymer supplier REHAU is highlighting the importance of building design in improving the sustainability of universities. The appeal follows the publication of the company’s recent report ‘Designing Healthy Schools and Universities,’ which surveyed 125 architects and specifiers specialising in educational structures on futureproofing facilities through high-performing building services. “People and Planet’s latest University League re-affirms a long-standing trend in the development of university facilities that must be addressed,” says Steve Richmond, Head of Marketing and Technical for REHAU Building Solutions. “Namely, that current building stock is behind both in terms of sustainability targets, and as far as industry attitudes are concerned. “This can be seen in research carried out in our latest report of REHAU’s Designing Healthy series, which looked at this sector. Our findings showed that 67% of architects and contractors we surveyed saw leaving high-quality buildings behind was a high priority in their work, with sustainability also ranking highly as a design priority. Contrasted against these clearly stated views, this new analysis makes for sobering reading.” The report goes on to highlight Office for Students figures showing that UK’s higher education student population is expected to grow by 12.3% between 2020-21 and 2024-25, and the ensuing need for additional campus buildings. This is contrasted against National Audit Office estimates that 60% of current educational building stock was constructed before 1976. Taking these figures into account, REHAU is advocating that contractors and specifiers working on university facilities ensure building services are chosen with healthy design principles in mind. Examples of implementable technologies raised in the report include Thermally Activated Building Structures (TABS), which are increasingly being adopted into new university structures and pair well with heat pump technology to provide sustainable heating and cooling. By selecting these sorts of solutions for upcoming projects, campuses can lower emissions while also improving student and staff well-being. Steve concludes: “The environment is a huge issue for students today, and will continue to rise in prominence as the effects of climate change become more apparent. Alongside this, rising tuition fees mean those attending university have become extremely aware of their status as consumers, and expect eco-conscious, healthy design to match their own priorities. “However, as our report and the latest analysis suggests, more needs to be done in this field. We would therefore implore contractors, specifiers and stakeholders in higher education to look at other options available, including campus-wide district heating systems, and examine available funding options such as the Public Sector Decarbonisation Scheme.” To download Designing Healthy Schools and Universities, click here.
BAM Wills JV has begun installation of Duradrain as part of the new €241 million N5 upgrade project, in County Mayo, Ireland. The product, a sustainable and recyclable combined kerb and drainage system, manufactured bygreen construction innovators Dura Products, will line a significant stretch of the new 20.3km dual carriageway between Turlough and Westport. It forms part of the biggest single infrastructural investment ever undertaken in the county. Duradrain was chosen primarily as a low carbon kerb and drainage solution, recording a carbon footprint of just 1.71kg of carbon dioxide per kg in its recent Life Cycle Assessments. In addition to its low carbon footprint, its lightweight nature increases productivity, while also reducing risk of injury during installation, making it a safer, simpler and greener alternative to concrete kerb and drainage systems. Dura Products, who supplied over 4km of Duradrain in October, and will supply another 10.5km between now and the New Year, uses a blend of recycled polymers to manufacture its products, ensuring it continues to divert waste from landfill and reduce demand for virgin plastic. The company has installed more than 400,000 units of its flagship product Durakerb in the UK since 2003, reflecting a burgeoning demand for sustainable construction solutions. BAM Wills JV, who signed the contract for the N5 upgrade project in October 2019, are equally committed to sustainable practice. Its parent company BAM Ireland recently partnered with the Irish Green Building Council to decarbonise Ireland’s building stock, promote circularity in the construction industry and enhance biodiversity, whilst also planting 150,000 trees to mark its 150th anniversary in 2019. Commenting on the installation, Steve Bennett, Managing Director of Dura Products said: “We’re delighted that BAM Wills JV selected Duradrain as its chosen kerbside and drainage solution for this project, and that we can help them continue leading the way for sustainable construction in Ireland. Knowing what this project will bring to the region in terms of accessibility, employment and road safety, it fills us with great pride to be involved.”
Coventry’s redeveloped Warwick Arts Centre has opened its doors as one of the region’s key venues for the city’s tenure as the 2021 UK City of Culture, with low noise level air distribution products supplied by Waterloo. Located on the University of Warwick campus, Warwick Arts Centre has been transformed into an environmentally sustainable multi-artform venue offering three state-of-the-art cinema screens, new gallery, spacious foyer, café and bar, alongside the existing large theatre, and other performance spaces. And coinciding with the long-awaited season when audiences were able to get back inside to enjoy the arts after months of lockdown, the October opening took on a special significance. With a proven track record of providing bespoke air distribution systems for spaces used for performance and exhibitions, this exciting project was the perfect challenge for Waterloo’s expert sales and technical teams. The Warwick 20:20 Project, which began in 2019, has transformed the original 1974 building into a vibrant showcase for the very best in contemporary art, events and entertainment that will appeal to the widest possible audience. Following the phase one refurbishment of the existing theatres, entrance area and restaurant, phase two began in autumn 2019 with the creation of a brand new building to house the new cinemas, large accessible ground floor gallery, new café and a welcoming, spacious foyer. When specifying air terminal devices for performance spaces, optimum air quality is not the only consideration. For moments when the audience should be able to hear a pin drop, low noise generation is crucial. Mechanical & electrical services subcontractor Dodd Group, working in association with engineering consultants Hoare Lea and supported by the Waterloo team, selected Waterloo’s Thermally Actuated Swirl Diffusers (SDACH) for the three auditoria to ensure the lowest possible noise levels. By using a temperature controlled actuator, this diffuser achieves very good control levels in both heating and cooling modes to provide ideal comfort at all times of year. In contrast, the exhibition galleries presented a different requirement. To ensure that the regularly changing exhibits would not be disturbed by air flow, Waterloo’s adjustable Hi-Flo Jet Diffusers (RWH) were chosen because of their ability to provide long throws and 360˚ rotation. Dodd Group’s mechanical engineer James McGugan said: “It was crucial that the air terminal devices chosen for Warwick Arts Centre delivered more than just optimum indoor air quality. Keeping noise levels to an absolute minimum for a performance venue was also top of our list when choosing who to work with on this project. Waterloo was able to provide exactly what was needed to achieve the required standards and the responsiveness of the team ensured on-time delivery.” The requirement for low noise levels also applied to the exterior of the building. Waterloo’s Large Format Fixed Blade External Louvres (WG-EF) were selected due to their 75mm pitch which ensures low noise and pressure drop characteristics whilst offering the necessary protection against water ingress. A polyester powder coating provides long term protection against the elements and a fully galvanized bird screen prevents unwanted inhabitants from nesting in the ventilation system. Air Valves were used in the toilets and for the areas immediately outside the toilets Waterloo specified the adaptable Louvre Faced Diffuser (DF41) which is ideal for integration with a variety of ceiling types whilst maintaining consistency in appearance. The DF41 is available with five frame styles and 14 different air pattern control core designs for vertical and horizontal diffusion.
Ashwood House is a development of Manhattan-style apartments in the desirable Surrey commuter town, Camberley. Situated in a converted 1960s office block, developer Berkeley Homes Southern Ltd needed to ensure the 116 luxury flats were as energy efficient as possible. This was a particular concern for the properties situated above the first floor car park, which has open walls to allow adequate ventilation of exhaust fumes. As a result, the specification stipulated a U-value of 0.25 W/m²K. Chris Body, Business Development Director at RPN Ltd, the specialist sub-contractor at Ashwood House said: “We approached several insulation manufacturers to discuss the different options available. Knauf Insulation’s Rocksilk® Soffit Linerboard Standard met the brief in terms of thermal and fire performance. It can be used on uneven substrates and looks fantastic – all of which were key priorities for Berkeley Homes.” Aesthetic appeal How the insulation looked was an important part of the brief as Berkeley Homes wanted a solution that would be aesthetically pleasing. Rocksilk®Soffit Linerboard Standard features a black glass veil facing, so no additional finishing was required. This meant that RPN Ltd has been able to install the slabs perpendicular to the ring beam to create a quilted effect across the ceiling. A high-performance solution The other specification factors were thermal performance and fire safety. Knauf Insulation’s Technical Support Team undertook U-value calculations to determine that 130mm Rocksilk®Soffit Linerboard Standard would be required. It is manufactured from Rock Mineral Wool, has a thermal conductivity of just 0.034 W/mK and is designed to insulate structural soffits in applications such as open sided car parks. It is non-combustible with the best possible Euroclass A1 reaction to fire classification, so will not contribute to the development or spread of a fire should it occur. Rocksilk®Soffit Linerboard Standard also has excellent sound absorption characteristics so will help to ensure that residents are not disturbed by the noise of cars parking beneath their flats. Better for installers The insulation was supplied by distributors CCF Ltd who delivered it to the site in line with the schedule of works. It was then installed by RPN’s specialist team. Rocksilk®Soffit Linerboard Standard is easier to install correctly than other insulants. The product recipe makes each slab rigid, which ensures the insulation maintains continuous contact with the substrate, preventing gaps that can reduce thermal, fire and acoustic performance. Rocksilk®Soffit Linerboard Standard is manufactured with ECOSE® Technology, Knauf Insulation’s unique bio-based binder that contains no added formaldehyde or phenol. It is made from natural raw materials that are rapidly renewable, and is less energy-intensive to manufacture than traditional binders, so it is more environmentally friendly. Products made with ECOSE® Technology are soft to touch and easy to handle. They generate low levels of dust and VOCs, and have been awarded the Eurofins Gold Certificate for Indoor Air Comfort. This means they are kinder to the installers who use them too. A safe solution Ultimately, using Knauf Insulation’s Rocksilk®Soffit Linerboard Standard means the Ashwood House car park ceiling not only looks aesthetically pleasing, but it helps to meet the increasing demand for non-combustible insulation in car parks too.

More than 3.32 million m3 of timber and panel imports were imported in Q3 2021, as the market achieves greater balance between supply and demand after nearly a year of record imports. Analysis of these statistics by the Timber Trade Federation (TTF) statistics show these import levels are more than 23% over Q3 2020 and, significantly, more than 10% higher than the last time Q3 volumes exceeded three million m3 – in 2007. Softwood is being imported in larger amounts from a more diverse range of countries over the past quarter, with Latvia, Finland, and Germany growing to account for 61% (1.1 million m3)of the 1.8 million m3 of softwood imported in Q3 2021. Other timber products, including hardwood, plywood, particleboard, OSB and MDF, have also seen clear increases in Q3 2021 as compared with the previous year. While some goods continue to be under pressure amidst buoyant demand, and logistics issues, the timber supply chain overall has proven resilient, with the timber industry in a strong position to meet demand in 2022. Nick Boulton, TTF head of technical and trade policy, said: “These latest statistics continue to reflect the incredible demand for timber products seen over the past year which have kept the UK on track to surpass previous import records. “After this record period the stock levels have returned back towards their pre-pandemic levels and the logistics supply chain is struggling to find sufficient space for further volume – so much so that in Sweden we are seeing some sawmills reduce their overall production volumes. “However, while we can see stock levels returning, the UK market is clearly in a different place compared to where it was two years ago, with the likes of HGV driver shortages, port delays and Brexit changes likely to continue to impact the market in the coming months. “Despite these challenges, these past 21 months have proven that the timber supply chain is resilient. We are in a strong position to meet growing demand for sustainable, low-carbon construction materials – both now and in the future. “As a low-carbon, low-energy construction material, timber is likely to grow as the material of choice among climate conscious architects, engineers, developers and planners in the UK. “With the tightest period of tension between supply and demand likely behind us, we can expect a return to more ‘regular’ activity in 2022.” Members can read the full report on the TTF website:
