ACPV’s ‘Lighthouse’ Office Tower Crowns Green Regeneration Of Local Area

4

The headquarters of Italian multi-utility company A2A is a major new urban development that comprises a new 144-meter-high tower with a contemporary design inspired by the industrial past of its location. International architecture and interior design practice Antonio Citterio Patricia Viel (ACPV) has unveiled the design for the new Milan headquarters of Italian multi-utility company A2A. ACPV’s project reimagines the company’s office spaces as capable of adapting to people’s everchanging needs at work, while reviving the local urban fabric with 6,320 sqm of new green public spaces.

VISION

The 144-meter-high office tower – named Torre Faro (lighthouse tower in Italian) – will connect Milan’s historic center and periphery by reactivating a north-south axis that runs from the city center through Via Crema and Piazza Trento all the way to ACPV’s Symbiosis business district, located just across the disused railway yard.

“The A2A Headquarters project creates a new vertical village for the firm’s operations. It is designed for people to enjoy working in the company of their colleagues and to encourage spontaneous professional and personal interactions,” Antonio Citterio, architect and co-founder of ACPV, says. ACPV won the architectural competition for the design of the new office building and the adaptive reuse of the existing structures in 2018. The new tower can accommodate 1,500 people in spaces that are flexible, open and are complemented by a green courtyard shared with the Museum of Energy – located inside the existing buildings that will be revitalized with the project.

Vertically, the tower is divided in the middle into two sets of office floors framed by the spacious entrance hall on the ground floor, the Sky Garden in the middle and the Belvedere on top. Just like the Sky Garden at mid-height (61 meters), the Belvedere provides panoramic views of Milan at 125 meters above ground. The tower’s large atrium and the suspended mezzanine create a generous and welcoming environment, enhanced by the multifunctional office spaces located on the floors above. The architecture of the buildingaddresses future professional needs by integrating flexible spaces – including co-working lounges and informal meeting rooms – that can be reconfigured for multiple uses.

The tower’s footprint is minimized by ensuring the site is open to public use, and by creating a new pedestrian-friendly urban district where local businesses can thrive. Beyond the A2A Headquarters, the urban regeneration project extends from the neighboring Piazza Trento to the closest metro station through via Crema. Enlarged pedestrian areas, two new squares, additional green areas and bicycle paths will turn the area into a diverse, multigenerational and attractive neighborhood.

“The new tower and the renovation of the firm’s existing buildings transform the architectural volumes to allow for a seamless passageway from Milan’s city center to the Porta Romana disused railway yard and the Symbiosis business district that is currently taking shape,” Claudio Raviolo, head of the project and partner at ACPV, says.

Expected to be completed by 2024, A2A’s new headquarters is located in an area of Milan that is currently undergoing profound transformation.

The new tower will redefine the role of the district in harmony with the nearby Symbiosis business district, facilitating the transfer of major service sector operations to this part of the city. The project confirms Antonio Citterio Patricia Viel’s deep expertise in the design of office buildings and workspaces. Recent works include NOVE, an office building in Munich (Germany); NEXXT – Fastweb HQ in Milan; and the restyling of Enel’s headquarters in Rome. www.citterio-viel.com

LLI Design's Total Refurbishment Of Highgate Edwardian Townhouse LLI Design has recently completed a total refurbishment of a 3 storey Edwardian townhouse on a leafy residential road in Highgate, a desirable residential area of North London. LLI Design's clients wanted to create a warm, comfortable home with modern touches. Although the house was in reasonable condition, the joinery and fittings throughout the house were dated, had been well used and looked tired.

Many of the period features had been stripped out and those that remained had not been maximised. The house lacked character and personality although it benefited from ‘good bones’, nicely proportioned rooms, a delightful garden and a handsome exterior. LLI Design felt that more could be made of the period features, enhancing some and reinstating others to bring out more of the Edwardian feel of the property.

The brief was to create a warm, comfortable and welcoming home referencing and emphasising the house’s Edwardian past as well as adding more contemporary elements to the scheme.

By subtle changes to the spaces and by adding texture, color and interesting material choices LLI Design was able to create a warm, comfortable and welcoming family home. LLI Design has achieved a harmonious and calm aesthetic throughout with modern touches within a timeless design.

LLI Design offers a comprehensive design service, taking projects from briefing through to Handover; creating beautifully crafted interiors for discerning clients. Recent projects include the interior design and modernisation of properties in Hampstead, Belgravia and Highgate including a 10,000 sq ft Victorian residence, a 12,000 sq ft new build home and the co-joining and replanning of two apartments to provide a single luxury penthouse. www.llidesign.co.uk

£5.4M Museum Extension Housing Iconic WW2 Plane Celebrated Thousands of visitors have now visited the £5.4 million extension to the Potteries Museum and Art Gallery in Stoke-on-Trent, which now houses an original Spitfire aircraft thanks to specialist project management from national property, construction, and infrastructure consultancy Pick Everard.

The project comprised the design and construction of a new 3,800 square foot, double height exhibition space with mezzanine and the alteration and refurbishment of the existing café space within the art gallery and museum, alongside extensive external landscaping.

Utilising a steel frame and rainscreen cladding, the new exhibition space has been designed with specialist structural glazing to allow the main attraction, the city’s iconic RW388 Spitfire Aircraft, to be exhibited.

The area also houses a flight simulator, model Hurricane aircraft and other exhibitions. Seeking an expedited project process to ensure scheduled delivery, Pick Everard – operating under Perfect Circle’s unique collaboration – was appointed as Stoke-on-Trent City Council’s multi-disciplinary construction consultant through SCAPE’s Built Environment Consultancy Services (BECS) framework.

10

VISION

Stoke-on-Trent is internationally renowned for its ceramics. The area has a history of coal mining, so specialist geotechnical design input was critical. In conjunction with the Coal Authority, an approach was agreed to backfill existing mine workings beneath the proposed building, which allowed construction to proceed.

Matt Hall, national director for project management at Pick Everard said: “We are delighted to have delivered such a historically significant development, which creates a lasting legacy for the city of Stoke-onTrent. Our expertise, combined with that from tourism and leisure architect Glancy Nicholls, has created a spectacular display space for the iconic Spitfire – a centrepiece the city can be proud of.”

The new spaces, constructed by Morgan Sindall Construction, allow the exhibition space to be enjoyed by people both inside and outside of the Potteries Art Gallery and Museum.

Cllr Daniel Jellyman, cabinet member for infrastructure, regeneration and heritage, said: “We are really happy with the outcome of this project. Not only have we managed to pay homage to one of Stoke-on-Trent’s true icons – Reginald J. Mitchell, the designer of the Spitfire plane – but we have also improved the aesthetics and accessibility for those walking to and around the site, through our new pedestrian links. The site will add tangible value and energise the community, providing them with a new landmark the city can be proud of.” www.pickeverard.co.uk

RecordBreaking Design and Build Project In The UK

12

Originally built in the 80’s, One Portsoken Street is 233,000 sq ft of premium office space for a range of tenants; located on the edge of the City of London, the iconic brutalist building is connected to both London’s financial sector and creative industries.

The UK’s largest design and build project is recently completed and now ready for occupation. Leading office design and build company, Oktra, have delivered the record-breaking project, redefining the boundaries of design and build by gutting the nine-storey building and filling what was once one of the largest atriums in Europe. The interior optimisation has led to a 20% increase in lettable space.

VISION

“We’ve fused the defining characteristics of design and build with comparatively traditional delivery and management processes in order to deliver the largest project in UK design and build history,” explains Craig Smith, Oktra’s Chief Development Officer.

“The result is a redefinition of what’s possible in design and build: One Portsoken is a ground-breaking project for Oktra and for the London design and build market. It’s a great thing to be involved in.”

The refurbishment includes restoration of One Portsoken’s original design elements in order to preserve the building’s history, with all modern finishes kept neutral in order to complement the design.

Standout elements include circular turrets, exposed concrete, terracotta floor tiles, exposed steel beams and sweeping London views from the top floor featuring the original atrium’s glass ceiling. One Portsoken Street is in the process of achieving a ‘Very Good’ rating from BREEAM, the world’s leading sustainability assessment method. 100% of site waste was diverted from landfill; 99.35% of waste was recycled, while the other 0.65% was incinerated to produce energy.

These recycling efforts reduced the project’s carbon emissions by 73%. The new One Portsoken features a lively public ground floor and landscaped open space. Floorplate sizes range from 10,000 to 30,000 sq ft and are designed to accommodate up to three separate tenants.

The building features impressive ceiling heights ranging from 4-10 metres and improved destination control with nine new lifts and a striking lobby space with a twoand-a-half-storey atrium. www.oktra.co.uk

CONCRETE CHANNEL WITH BASALT FIBRES – NEW ERA BEGINS FOR HAURATON Hauraton makes concrete material even more efficient for modern drainage technology by enhancing the formulation with natural basalt fibres. The addition of mineral or textile fibres increases maximum stability, strength, and impact resistance. By amplifying the impact resistance, the more robust and durable the product. This is particularly important for components that are exposed to considerable dynamic stresses, in this case, drainage channels subject to vehicles at high speeds or regularly trafficked by heavy loads.

The basis of basalt rock is available all over the world in large quantities which is formed naturally on the earth’s surface. By combining basalt fibres with the well-known material concrete, both the structure and the service life of the product is increased. Since the end product is a purely mineral mixture, there is no need for material separation during disposal.

This protects the environment as it is simply fully-recyclable at the end of the product's life cycle. Basalt fibres have outstanding properties.

They can withstand temperatures of up to 800°C and are highly resistant to alkalis, acids, salts, oxidation and radiation.

Drainage systems made of basalt-reinforced concrete will assure longer performance. Basalt fibres are mineral fibres that have a higher melting temperature, better resistance to water, acids and alkalis, and more positive flexural strength. The energy consumption during production also clearly speaks in favour of basalt fibres, as basalt it has the lowest CO 2 footprint. www.hauraton.co.uk

ADSA HELPS DEVELOP A FUTURE WORKFORCE The success of an apprenticeship scheme created by the Automatic Door Suppliers Association (ADSA) is helping to develop a future workforce for the industry. A third cohort of Powered Pedestrian Door Technician Apprentices started South Staffordshire College in June with places for a further course in September now being booked. Members of the initial group, which began their two-year apprenticeship in March 2021, are completing projects for end point assessments with should be fully qualified by the end of the year. A second, which started last September is concluding its first academic year with another to follow.

Says ADSA Managing Director Ken Price, “It is good to know that the industry has embraced the opportunity to develop a future workforce utilising the apprenticeship. It provides a thorough learning opportunity, combining academic study with on-the-job experience. The automatic door sector is considered niche within the wider building products and construction industry – but it is one that requires a particular set of skills and learning to demonstrate competency and meet exacting standards."

“Automatic doors, gates and entrances may be widely used within commercial and public buildings, enabling convenience and accessibility but awareness of the businesses that make, install and maintain them may not have been as prominent as it might, which has led to a skills gap within the industry. ADSA’s efforts to professionalise it through the provision of end-to-end learning and development opportunities should help attract and retain talent for the future.”

Yorkshire Housebuilder Specifies Stelrad Radiators For All Its Developments Radiators are the key sharer of heat around homes in the UK and many housebuilders are specifying designer radiators because they want their customers to benefit from a premium product as part of the new home’s specification.

One of these is Erris Homes, based in Leeds.

Erris Homes is a provider of modern and luxurious new family homes across Yorkshire.

The company has chosen the Compact with Style design radiators from Stelrad – another Yorkshire-based company – with more than two and a half million radiators a year manufactured at its manufacturing plant in Mexborough, near Rotherham in South Yorkshire.

Purchasing radiators from a locally based manufacturer is definitely a plus for Erris Homes as it means it is not only supporting its local supply chain but also minimising its environmental impact due to the reduced

distance of transport for the radiators from the National Distribution Centre alongside the Stelrad factory to the sites around Yorkshire.

The Compact with Style offers a clean, crisp, flat fronted radiator with a horizontal lined fascia.

The subtle architectural look and feel of the Compact with Style is combined with value, range and availability to provide a sophisticated, designer styling for any room, commercial or domestic, at affordable prices. It’s available in 126 different models – horizontal, vertical, loline and coloured versions. www.stelrad.com

Working Towards Better Workspaces Across Europe, co-working is continuing to buck the trend of traditional office decline, with an estimated growth of 158% over the next two years. With many companies not demanding a return to the office but conversely trying to remove people from working at home, co-working spaces have proved to be an excellent solution.

These were then perforated on-site with different sized holes to give an unusual three-dimensional effect. Not only do the high performance panels offer an interesting textural and visual appeal but they absorb the ambient noise created by talking as well as the echoes and reverberation caused by the hard surfaces and large glazed areas.

A good example is here at LUI House in Herford, Germany. Archwerk Architects have developed this four-storey building into a sustainable co-working hub which is fully self-sufficient using heat pumps and PV cells.

Founded on the Cradle-to-Cradle design concept, Troldtekt’s natural and inherently sustainable panels are available in a variety of different surfaces and colours and contribute positively to a building’s BREEAM, DGNB and LEED ratings. In addition to their high sound absorption and tactile surface, they offer high durability and low-cost lifecycle performance.

Complete with large break-out areas, hot desks and meetings rooms, the building exudes an aesthetic and inspiring ambience with high-quality furnishings and top-class media technology. With large open spaces and hard surfaces, the architects specified ultrafine bespoke Troldtekt wood wool acoustic panels in a natural grey.

Available in various sizes and in four grades, from extreme fine to coarse, the panels can be left untreated or painted in virtually any RAL colour. www.troldtekt.co.uk

Sto Acoustic Ceiling System Brings Calm To Refurbished Museum

26

An acoustic ceiling system provided by Sto has created a quiet and calm environment for a museum in Hampshire. The StoSilent Distance system has been installed in Petersfield Museum, which has been created by the conversion and refurbishment of Victorian premises that previously housed a police station and court house.

“The StoSilent Distance system is wellsuited to this type of refurbishment project,” comments Sto’s acoustics project manager, James Gosling. “It delivers outstanding acoustic performance, but also offers tremendous flexibility as it can be used to create large seamless ceilings, sharp joints and creases, or curved ceilings and vaults. This gives architects and designers great freedom while still allowing them to accommodate the existing structures found on a refurbishment project such as this.”

INTERIOR DESIGN

The Sto system was specified for the building by Hampshire County Council Property Services, as part of a project to create a series of new, welcoming spaces at the museum.

The StoSilent Distance system can function as a suspended ceiling, or as a wall-covering over a cavity. It features a metal profile subconstruction fitted with acoustic panels, which are manufactured from expanded glass granulate, making them lightweight and easy to handle, and allowing them to be adjusted to suit any room shape and create a smooth, seamless surface. Different system variants are offered to suit different types of application.

The boards were finished with StoSilent Décor M, a spray-applied acoustic plaster which can be tinted to match an extensive range of shades from the StoColor system.

This solvent and plasticiser-free plaster creates a classic fine-stipple finish which is ideally suited to a museum environment.

It is also Natureplus approved and easy to refurbish.

The construction work formed part of the museum’s £3.75m ‘Pathways into the Past’ expansion and refurbishment project. This has seen the museum’s buildings and exhibition spaces undergo a complete transformation, along with the creation of an exciting new outdoor courtyard space. www.sto.co.uk

DOORS, WINDOWS & GLAZING

NEWLY RENOVATED CAMBRIDGE CHURCH BLESSED WITH WARMTH FROM SECONDARY GLAZING INSTALLATION Downing Place United Reformed Church is situated in Cambridge. It was formed in June 2018 following the joining of Emmanuel and St Columba’s United Reformed Churches. The redeveloped St Columba’s site has been extensively renovated and main contractor Coulson Building Group contacted Selectaglaze to discuss secondary glazing solutions for the purpose of thermal retention.

56 units were installed; comprising of four Series 45 side hung casements in the Chapel and 52 Series 46 slimline fixed lights installed in the Nave. A large circular primary window in the Nave was perhaps the most complex treatment due to its shape and elevated position. A timber mullioned cartwheel frame was crafted to securely hold the secondary glazing. Seven bespoke Series 46 fixed light segments were made for it and glazed with 6mm toughened glass to give additional rigidity and structural strength.

The church has now been made more thermally efficient with the inclusion of secondary glazing and DPURC should start to see a reduction in heating costs, with less heat escaping and uncomfortable draughts practically eliminated. www.selectaglaze.co.uk

HELPING TO PRESERVE AN INDUSTRIAL LANDSCAPE Two former furniture factory buildings in East London have been transformed into high-end apartments with the help of Crittall windows. Long Street in the Hackney conservation area was a key component in Shoreditch’s industrial heritage.

The four-storey structural steel-framed blocks were built in Long Street in 1959 with plenty of natural daylight and generously sized lifts for transporting uncut sheets of plywood to the upper floors. The two blocks now form part of a luxury residential development, Long and Waterson. Architects Fletcher Priest have taken their design cue from the industrial lineage of the area, retaining original external brickwork and window settings and adding two rooftop penthouse levels creating a total of 71 apartments.

Crittall Corporate W20 and MW40 systems were specified, in fixed and opening format together with Crittall cold form tubular doors that meet the RC3 burglary resistance security standard; a choice that preserves both the original appearance and the industrial heritage of the area. www.crittall-windows.co.uk

SAFE BY DESIGN Helping ensure the safety of pedestrians, TORMAX automatic sliding door systems can be fitted with a full-glass screen behind which the door leaf can recess as the entrance opens. This removes the risk of the sliding door mechanism being interfered with or blocked by anyone, allowing immediate clear opening as people approach the door. To keep the entrance looking smart, the pocket screen features a lockable hinge, allowing it to be quickly opened out for easy cleaning and for any accumulated debris to be removed.

“Without the screen, if someone is, for example, leaning on the side panel as the door opens,” explains Simon Roberts, MD for TORMAX UK Ltd, “the sensors on the outer edge of the leaf will pick up the obstruction and cause the door to stop moving and return to the closed position. This is obviously unhelpful for those walking through the doors, as the sensors on the inner edge then respond to the obstruction in the doorway and try to re-open.”

In particularly busy locations, such as shopping centres and hospitals, the pocket screen can significantly improve the flow of foot traffic into and out of the building whilst protecting those people on either side of the doors.

Aesthetically it also neatly finishes off the doorway, creating a sleek and minimalist entrance that is safe for all users. TORMAX has always been at the cutting edge of safety when it comes to automatic access and their range of revolving, sliding, swing and folding doors feature sophisticated sensors that can include infra-red, radar and light beams, delivering precise movement control in all directions. www.tormax.co.uk

Aluprof Helps Push The Boundaries Of Passivhaus

by Wojciech Brozyna MD of Aluprof UK

When we talk of Passivhaus we generally think of ‘one-off’ grand designs style projects where costs seem no objection, but this is a dated view as Passivhaus is rapidly becoming a mainstream construction methodology. Recent cost analysis from the Passivhaus Trust suggests that a Passivhaus certified residential scheme is around 8% more expensive than an equivalent competitive tender build; further analysis suggests as Passivhaus claims more middle ground in construction, the extra-over costs can reduce to just 4%.

Passivhaus is not all about cost, it is about a commitment to net-zero carbon emissions.

Currently housing stock is accountable for approximately 35% of our total global energy consumption, so insulation is key in order to reduce our reliance on energy and our ability to reduce and phase out fossil heating fuels, such as gas. There are also health benefits and fuel poverty issues which are completely covered by adopting a Passivhaus construction.

DOORS, WINDOWS & GLAZING

Given the background growth of Passivhaus, Aluprof are delighted to announce their involvement in what is claimed to be the world's largest lowcarbon student residential development taking place in Bristol for The University of the West of England (UWE). The new development taking place at the Frenchay Campus covers approximately 65,000m2 and provides 2,250 new student residences. The scheme started on site in 2021 and is set to have the first phase complete for first-year student intake in 2023. Designed by Passivhaus Trust members Stride Treglown Architects and QODA Consulting, the new halls will offer carbon neutral accommodation which falls inline with the University’s ‘2030 strategy’.

The project follows on from what now will be the second largest student accommodation project completed to date, ’The House’ at Cornell Tech in New York. Aluprof UK became involved in the design development of the scheme from RIBA Stage 2 and worked alongside Stride Treglown, QODA Consulting and Turner & Townsend to develop a high performance facade solution which helps the new development to achieve Passivhaus standards.

Facade detailing and cost analysis support was provided by Aluprof UK prior to tender release to ensure budgets met stakeholder's expectations.

Aluprof UK also offered tender support to VINCI Construction UK, the main contractor awarded the scheme, in the careful selection of Aluprof experienced subcontractors to deliver a compliant tender. Aluprof UK have been involved in a collaborative process from RIBA Stage 2 onwards and will continue to support the project through to its completion. Denval, located in Cardiff, have been nominated to install the high insulation windows and doors on the project.

Alex Wysom, Operations Director at Denval takes up the story, “Aluprof worked with Stride Treglown Architects to provide a comprehensive specification for their high performance Passivhaus certified MB104 window system from the earliest stage, Denval provided cost plan and technical support to the project management company and subsequently

the main contractors who were providing tenders for the scheme. “Since the earliest stages of our involvement with the project, we have worked closely with Aluprof, who have supported Denval with excellent technical information, to enable the most cost effective solutions to be established for this large Passivhaus development".

The Aluprof systems specified for the project consist of MB-104 SI (Passivhaus Certified) windows and doors and the MB-SR50N HI+ (Passivhaus Certified) curtain walling system. The specified finish uses a Super Durable Polyester or Class 2 powder coat in an AkzoNobel Interpon ‘Gold Pearl’ colour, reference YY217E. Aluprof have long been recognised across Europe for providing Passivhaus certified products and Aluprof UK are active members of the Passivhaus Trust in the UK. The project is to be completed in two phases, first is the redevelopment of Carroll Court on campus where student houses have been demolished to make way for the start on site in November 2021 by main contractor Vinci Construction. Phase one will see the 900-bedroom Stride Treglown designed buildings take shape and will be the first to complete in 2023. Installation of the Aluprof windows and doors on site is anticipated to begin in July 2022. The second phase will see the redevelopment of three existing car parks offering a further 1,350 rooms that will comprise phase two are expected to be available one to two years after the completion of phase one.

Once complete the new buildings will yield a 54% reduction in running costs and carbon emissions compared with a typical building built to current building regulations. Aluprof UK are delighted to be leading and supporting the development of Passivhaus construction across the UK and are already working with specifiers and developers on further schemes to help active the UK’s challenge of achieving carbon neutrality by 2050. www.aluprof.co.uk

SELECTAGLAZE CURVED ON PLAN UNITS CREATE A SPLASH AT KIDDERPORE HALL Working with Mount Anvil, a swimming pool area in a Grade II Listed home has been restored to its former grandeur, with the assistance of Selectaglaze sealed units and curved on plan secondary glazing. Kidderpore Hall sits looking over North London, in what was referred to as the Childs Hill neighborhood of Hampstead; once a relatively rural area. It has been beautifully reimagined through extensive refurbishment and brought back to a livable state as a single family home.

One of the areas of the house which needed particular attention was a new pool and spa area in the basement.

The original single glazed sash windows did little to provide heat retention. Selectaglaze secondary glazing was chosen to assist in upgrading the thermal insulation in this Grade II Listed building. To ensure maximum U-values were gained in this exposed corner of the building, 24mm double sealed secondary glazed units were required with obscure glass to provide privacy. Six window and one door were treated with Series 41 side hung casements, glazed with 4-16-4 gas filled sealed units.

However, to match the sightlines of the bay window framing the jacuzzi, curved on plan units were specified. www.selectaglaze.co.uk

Heat Pumps Now Officially Less Expensive To Run Than Gas Boilers….

For the first time, efficient heat pumps in the UK are now cheaper to run than gas boilers. That’s according to new analysis from RAP - The Regulatory Assistance Project (RAP)® - an independent, non-partisan, non-governmental organisation dedicated to accelerating the transition to a clean, reliable, and efficient energy future. This exciting news for renewables in the UK is mainly down to gas prices increasing more than electricity pricing. This news has been welcomed by leading air to water heat pump manufacturer LG. The detailed analysis shows that with a coefficient of performance (COP) of 3, a heat pump starts to become cheaper to run than a gas boiler. In the past, a COP of around 3.7 was required to achieve the same running costs as a gas boiler. Heating with a gas boiler will cost households an average of £934 per year, up from £579. A very efficient heat pump will only cost £723 per year, up from £536 per year. For an average household this is a 27% saving of £261 per year.

Recent press coverage by EUA claiming that heat pumps will cost more to run were based on pessimistic assumptions of heat pump efficiency assuming they only achieve a COP of 2.5. EUA data also assumed best possible efficiency for gas boilers (92%)

38

which is not supported by real-world data. In-situ monitoring studies of UK installed condensing boilers have shown an average measured boiler efficiency of less than 85%, highlighting perhaps the sheer number of elderly, inefficient boilers that are still out there in homes around the country.

As a result, under the April 2022 energy price cap for UK energy suppliers, it can confidently be stated that a heat pump will be cheaper to run than a gas boiler if its "COP" is at least 3. This is a very important 'tipping point' for the UK and may only make the case for air to water pumps even stronger as the volatile price of gas continues to increase as it has done over the past 12 months. “Whilst higher prices for gas and electricity help no one, the prices reflect the global issues that confront the costs surrounding fossil fuels,” says LG’s Peter Spurway. “Whilst electricity is needed to run heat pumps, their ability to deliver up to four and half times as much energy in the form of heat and hot water as they consume clearly makes them a very serious option to the traditional gas and oil fired boilers that run the heating and hot water of so many homes in the UK".

"The impending arrival of the ban on using traditional boilers in new build properties from 2025 looks ever more likely to be rolled out to replacement heating systems in existing homes as well and heat pumps are clearly becoming the best option – with heat pump technology proven and growing in importance across Europe and being seen as a sensible and energy efficient solution here in the UK.” partner.lge.com/uk

DOMUS VENTILATION MVHR SYSTEMS PROVE IDEAL RETROFIT SOLUTION FOR LONDON RENTAL DEVELOPMENT Domus Ventilation’s HRXE-HERA® Mechanical Ventilation with Heat Recovery (MVHR) systems have been specified for the be:here Hayes build-to-rent residential development in West London. When the building was designed, Domus Ventilation’s Silavent MVHR ceiling mounted units were installed. These are now being gradually replaced with Domus Ventilation’s latest MVHR model, HRXE-HERA®. As a retrofit solution, HRXE-HERA® has proven ideal for be:here Hayes as they readily use the existing Domus ducting.

Domus Ventilation’s HRXE-HERA® MVHR have proved an ideal solution. It filters and pre-warms fresh air drawn into the apartment using the heat from waste stale air extracted from the kitchen and bathroom using a heat exchanger. It’s advanced heat exchange proficiency enables up to 95% of waste heat to be recovered. It comes with 100% thermal (summer) bypass which automatically activates when the air temperature reaches a pre-set level, allowing in cooler, fresh, filtered air without warming it through the heat exchanger.

The smart design of the HRXE means there is no reduction in airflow when operating in bypass mode. www.domusventilation.co.uk

SMOKE EXTRACTION SOLUTION Fire safety remains a top priority for all involved in the construction industry, with many manufacturers offering many solutions. GEZE, a leading manufacturer of door and window control systems, offers one more, which they believe is a unique solution for smoke extraction systems in the market place.

The RWA K 600 retractable arm drive can be fitted to emergency exits on escape routes and in the event of a fire it can be used as a fresh air supply which when the fire alarm is sounded the door opens automatically allowing a large amount of air to flow into the building and forcing smoke out. The powerful drive with¬¬ high torque opens a door to 90 in less than 60 seconds. Yet the door remains readily accessible due to the freely positioned activation of the lever by means of a pressure roller.

The RWA K 600 is perfect for use in supply air systems where large opening angles are required, it is suitable for single and double leaf smoke and heat extraction fresh air doors and can be installed on both the hinge or opposite hinge side. Said Andy Iredale, National Sales Manager for Automatic Doors and Window Control, “The RWA K 600 is a unique solution in the extraction of smoke from a building in the case of fire.

TBA FIREFLY SYSTEM SUB-DIVIDES SUPERMARKET ROOFSPACE During the recent pandemic supermarket chains have had to continue with property maintenance and improvement programmes to ensure the safety of their premises, including a store in Staffordshire where the APOLLO Lite 30:30 barrier, manufactured by TBA FIREFLY TM , was installed within the roof- space as part of a major refurbishment project. The work at the store was carried out by sector specialist, The B Team.

All of the APOLLO Lite 30:30, together with the heavy duty stainless steel staples and other ancillary Firefly products, have been supplied by distributor, CCF. All of The B Team’s work had to be carried out while minimising any disruption to the store’s long hours of business, with the new APOLLO Lite fire barriers being concealed above the building’s reinstated suspended ceilings. The APOLLO Lite 30:30 has been developed for use in vertical separation or compartmentation situations, offering 30 minutes integrity and insulation thereby exceeding the minimum requirements of the Building Regulations. It is widely specified to form fire barriers within roof voids and floor voids in many different property types, including tower blocks and other HMOs. The flexible woven and non woven glass fibre material is easy to cut and fix and is treated with a proprietary coating to improve its fire performance properties and therefore prevent temperatures rising in adjoining areas.

The system has been fully tested to BS 476 Parts 20 &22 and is third party certified by IFCC. The six metre long rolls of APOLLO Lite 30:30 have a minimum thickness of 6mm and are installed using specialist staples as well as heat resistant adhesive. www.tbafirefly.com

How To Specify Outdoor Power Distribution Units To Meet Anticipated Demand Adding a power supply infrastructure to an outdoor public space, such as a courtyard or enclosed garden, is an excellent way to unlock the potential for holding events and creating more revenue-generating space. But how can you ensure that the proposed power supply will meet the demands and needs of the site given the versatility that comes when an outdoor space is power-connected?

Over-specifying the services infrastructure and distribution units could be a costly mistake. But under-specifying could result in the need to hire temporary generators or run lengthy trailing cables from adjacent buildings, creating avoidable trip hazards.

Whether you are a site owner or an architect or landscape architect working to enhance an outdoor space, the starting point is to ask three basic questions about demand and needs: 1) How do you envisage that your proposed power unit or power distribution system will be used?

2) How many power sockets will be needed?

3) Would the location also benefit from a supply of water or data connectivity?

42

VIEWPOINT

Designing-in versatility - Equipping any outdoor space with a power infrastructure is going to add a great degree of flexibility of use to the location. But when designing the power supply, it is important to have a picture of the typical and maximum usage that will be required.

Going back to basics, why is the site going to benefit from a power infrastructure? For a business such as a restaurant, bar, café or hotel, the outdoor space could add additional areas for eating and drinking primarily. Such uses would typically require the power distribution to provide access to sockets for lighting, till points, AV equipment or outdoor serving

The type of power unit you choose will depend on how the site will need to look or be used when the space is not being used for events, catering, etc. Both the pop-up and in-ground units can be hidden away when they are not in use, with the only evidence being a cover which can be designed to match surrounding surface materials.

A power bollard has a permanent presence, but the designs available from Pop Up Power Supplies® are elegant to avoid the utilitarian appearance that would be expected with a typical feeder pillar.

What should each power unit provide? - Consider what the electricity demand will be for the equipment that is to be connected to ensure the power supply units can handle the load. This is an area where Pop Up Power Supplies® has a wealth of expertise to help, given our experience of providing power units for a diverse range of sites across the UK, from Caerphilly Castle visitor centre to Chelsea FC’s Stamford Bridge pitch.

The retractable power units available from Pop Up Power Supplies® can be specified to provide a total power supply from as little as 63 amps right up to 600 amps. In ground units offer the option of 63 amps or 125 amps and power bollards provide up to 125 amps. The sockets in all can be configured to suit usage requirements.

points such as mobile counters or drinks dispensers. But is that the limit to such a site’s potential? Could it also be used as a stage are for outdoor music performances and other entertainment, for example. And if so, would your proposed power supply solution accommodate these requirements too?

Also think about the location of the power units in relation to how they will be used.

These units can also be designed to provide a water supply or data connectivity. Access to water can be particularly useful for ground maintenance and cleaning purposes, so consider that too and the units can become extremely useful assets. www.popuppower.co.uk

If the site is to be used for market stalls, where will the stalls be set up on site and where will the main pedestrian routes be? Installing power units in the correct locations will help reduce the risk of trip hazards as cables trailing across the main footfall areas can be minimised or avoided completely.

Once you have a picture of how the site could be used, it is time to consider how you feed power to the locations across the space. This can be achieved with the installation of a Pop Up Power Supplies® power distribution unit in one of three forms: 1) Pop up, retractable power unit – this is submerged in the group until it is needed, and raised/lowered using a turning handle.

2) Flip-lid, in ground power unit – this is permanently submerged in the ground with access provided via a flip-lid which can be used while the lid is locked down.

3) Power bollard – a street furniture element which has power sockets integrated, accessible as required behind a lockable cover.

When Does Cost Outweigh Conservation?

Paul Trace of Stella Rooflight discusses the importance of maintaining the historical integrity of buildings during an economic downturn.

It’s hard to imagine a tougher economic climate.

Having emerged from the pandemic, businesses and homeowners are beset by the rising costs of fuel and materials, economic shockwaves from the war in Ukraine and stark warnings of 11% inflation from the Bank of England. This is compounded by ongoing building supply issues that are still being experienced as a result of Brexit.

As the cost of most building materials such as timber, steel and glass continues to increase, the impact will most keenly be felt among those working on selfbuild, renovation and extension projects. No doubt, this perfect storm of economic woe has resulted in the postponement of many such project, however, for those that are pressing on, most will be looking to cut back on budgets in whatever way they can and compromises

44

on quality are inevitable. Fortunately, when it comes to the majority of building projects, especially new build or modern homes, there is plenty of choice out there for most materials and components, and shopping around a little can yield useful savings.

However, if your project is historically sensitive, for example a Listed building, barn conversion or a property in a conservation area, then choices may be more limited.

There are many examples of imitation ‘conservation’ products on the market, for example plastic being used as a replacement for cast iron rainwater goods, windows and rooflights. While these products might offer a cheaper alternative, there are few, if any examples where these materials should be considered appropriate.

VIEWPOINT

According to Historic England, the public body that looks after England’s historic environment, in their Materials for Historic Building Repairs article 1 “The use of authentic traditional materials helps to retain the character of historic buildings and in turn supports traditional industries and vital craft skills. They argue that “some materials can actually harm the existing historic fabric and speed up deterioration”, and urge for consideration to be given to “the potential durability of the material used and its future maintenance requirements”, they conclude in saying “what might seem like the cheapest option might not always work out so in the long run”.

Looking more closely at the rooflight market; just because something is sold as a conservation product, that doesn’t automatically make it suitable for all building types. If a rooflight is going to be introduced it has to meet the conservation specifications of that particular area or type of building. If your building is Listed or in a conservation area then the criteria for using conservation rooflights are much stricter and you should always gain approval, not only for their use but also the manufacturer that you would want to use. There are only a handful of companies that specifically make conservation rooflights and even fewer who design, manufacture and assemble in the UK. Many conservation rooflights available online are simply other products which have been spruced up to look like they meet the requirements of that type of product.

There are many elements which go into a genuine conservation design and price is always a reflection on quality. If a conservation rooflight is all frame, then there is little point in having one. Genuine conservation designs should be manufactured with slim, clean lines and a low-profile to match the roofline. A number of skylight companies try to produce conservation rooflights using modern bulky aluminium or plastic profiles, which sit proud of the roofline, particularly slate. It is widely accepted that most authentic conservation rooflights are manufactured from steel because it provides great strength while offering a slim profile and excellent glass to frame ratios. There are many types of steel conservation rooflights and for unrivalled protection and lifespan, one should always consider 316 stainless steel, which will protect against the common issue of rust.

Consideration should also be given to the viewable area of a rooflight. Large rooflights do not always guarantee lots of light and you should always check what the finished viewable (often referred to as clear viewable) area of the rooflight will be. You might think that a conservation rooflight with a whole frame size of 900mm (w) x 1200mm (h) would have a similar clear viewable area regardless of the manufacturer, but you would be wrong and bulky framed modern types or the flat rooflights posing as pitched conservation styles will let in considerably less light than a genuine steel framed version.

Understanding what constitutes a genuine conservation product is vitally important in an age where we are witnessing far too many cheaper, often imported, plastic products, being used in sensitive buildings across the UK. The use of such products very rarely contributes anything to historic character of a building, indeed the visual impact of using modern materials on older buildings usually has quite the opposite effect. While there is no denying that bone fide conservation products are more expensive - and hopefully the reasons for this have been demonstrated above - builders, architects and homeowners must resist the temptation to use alternative materials when looking at areas in which to cut back on budgets. As we continue to feel the economic squeeze we can only hope that decisions are taken in the best interests of the long term preservation of our heritage and that cost cutting does not end up having a long term impact on our important historical buildings. www.stellarooflight.co.uk

Looking to complete the exclusive lodges, roofing contractor, Summit Roofing Solutions utilised a number of CUPA PIZARRAS’ products. Likewise, the project team also chose to use the company’s natural slate to complete a renovation of Tregenna Castle’s original roof. The lodges and castle are subject to difficult coastal conditions, including extreme winds and sea spray.

As such, the project team needed access to roofing solutions that could deliver long-lasting, durable performance. Likewise, given Tregenna Castle’s status as a Grade II listed property, the team had to ensure that any selected products were able to deliver a traditional aesthetic, whilst still providing modern performance. Fortunately, CUPA PIZARRAS natural slate was able to meet all the desired criteria.

Therefore, roofs on the lodges at Tregenna Estate exclusively used CUPA PIZARRAS’ 400mm x 200mm CUPA 12 natural slates, fixed using 100mm stainless steel hooks that were also produced and supplied by CUPA PIZARRAS. Notably, Summit Roofing Solutions was able to install the natural slate as a closed mitred hip system. In doing so, the project team ensured that all slates lined up perfectly with one another, which is only possible on account of the products’ uniform size and quality.

This was particularly important on the lodges, where sections of roof were stepped down in certain locations and visible from ground level. Speaking on the project at Tregenna Estate, Adam Palmer, Company Owner of Summit Roofing Solutions commented: “Upon receiving the brief, we recognized that CUPA PIZARRAS’ solutions could help us to meet all key project goals. What’s more, the company helped us to overcome logistical challenges.”

In anticipation of the event, enhanced security provisions were put in place on the site, which made the logistical side of the project more difficult.

Thankfully, through its extensive distribution network, CUPA PIZARRAS was able to devise a well-considered delivery and logistics plan to ensure that supplies could reach the project team at critical times. CUPA 12 was chosen for this prestigious project as it is a high quality dark grey slate with a smooth finish.

With a life span of more than one hundred years and very little maintenance required, natural slate is a durable, weatherproof product, un-matched by artificial alternatives. CUPA 12 has also received approval from Snowdonia National Park as a Welsh Slate alternative and has been certified by BRE Global as A+ for its quality, transparency, and sustainability credentials. www.cupapizarras.com/uk/

Following project completion, the Tregenna Estate played host to key stakeholders attending the G7 Summit in Cornwall, including the Prime Minister and US President Joe Biden.

PROJECT INSIGHT

The Anzeiger-Hochaus in the centre of Hannover, built in 1928 and 51 m high, with its characteristic facade in the style of ‘brick expressionism’, is a unique example of German skyscraper construction. The city’s planetarium was once located under the 17 m high dome, and subsequently the highest cinema in Germany. The 2019 renovation included a completely new Nordic Copper Special Patina dome roof meeting strict listed building protection.

Sustainable Restoration With Nordic Copper Although considered to be a thoroughly modern material offering limitless possibilities for contemporary architectural design, copper is also – of course – one of our oldest building materials, traditionally covering the domes and spires of city skylines. Nordic Copper Special Patina has been developed specifically to help with repairs, restoration or extensions to historic buildings. Copper’s unique architectural qualities are defined by its naturally changing patina – which cannot be successfully replicated using other materials with surface coatings.

Within a few days of exposure to the atmosphere, a copper surface begins to oxidise, changing from the ‘bright’ mill finish to a chestnut brown, which gradually darkens over several years to a chocolate brown. Continued weathering can then result in development of the distinctive green patina – or blue in coastal locations. This process is an expression of the metal’s propensity to revert to mineral compounds that resemble the ore from which it originally came. Some rainwater is needed for the patina to form and its rate of development will depend on the water “dwell time” on a surface.

As a result, vertical cladding and sheltered surfaces will take much longer to patinate naturally than exposed roofs. Airborne pollution also increases the rate of patination, which therefore takes longer in more remote, cleaner environments than in cities or industrial areas. The complex combination of factors determines the nature and speed of development of patination, giving copper unique, living visual characteristics developing over time in response to local conditions.

50

Natural Surface Treatments - All these naturally developing surfaces can be provided straightaway with the ‘Nordic Copper’ range. The factory processes involved are generally similar to those taking place over time in the environment utilising copper mineral compounds, not alien chemical processes. The surfaces form an integral part of the copper, generally continuing to change over time, and are not lifeless coatings or paint.

The architectural range includes Nordic Standard ‘mill finish’ and Nordic Brown pre-oxidised copper, offering lighter or darker shades of brown determined by the thickness of the oxide layer.

Copper alloys include Nordic Bronze and Nordic Brass, which can also be supplied pre- weathered. The innovative Nordic Royal is an alloy of copper with aluminium and zinc, retaining its golden colour and simply losing some of its sheen over time with exposure to the atmosphere to give a matt finish.

But of particular interest to architects and conservation specialists working with historic buildings are the extensive Nordic Blue, Nordic Green and Nordic Turquoise ranges. They have been developed with properties and colours based on the same brochantite mineralogy found in natural patinas all over the world. As well as the solid patina colours, ‘Living’ surfaces are available for each with other intensities of patina flecks revealing some of the dark oxidised background material Individually Developed Special Patinas - Copper’s patina film provides impressive protection against corrosion and can repair itself if damaged, defining the exceptional longevity of copper cladding – counted in hundreds of years.

Suomenlinna Church, built in 1854, is on the Unesco world heritage list as a unique example of military architecture. The presence of the church on the Helsinki skyline is significant and patination of the master tower – which doubles as a lighthouse – particularly important. The new Nordic Copper Special Patina roof does not just resemble the old one but was actually made from recycling the original copper

But repairs and restoration – following substrate or structural failures, or other damage – or extensions to historic copper buildings may still be needed. The Nordic Copper Special Patina system is designed specifically to help architects with restoration projects. Aurubis has several decades of experience of developing unique patinated architectural copper products, successfully applied on historic – including listed – buildings in the UK and abroad. With Nordic Copper Special Patina, unique pre-patinated copper material can be produced to match naturally patinated copper, especially for historic buildings.

An original sample from the building is used but initial development can be started with the help of a Special Patina Tool (which can be downloaded from www. nordiccopper.com and printed). The card is simply placed on the original copper surface and photographed.

Meg Makes A Splash!

Located in the foothills of the Franklin Mountains in El Paso in Texas, Camp Cohen is one of three new waterparks designed to celebrate the culture of the city’s diverse communities. Parkhill Architects were appointed by the City Authority to design them and Camp Cohen was the first.

It was decided to use Abet Laminati’s MEG exterior grade laminate for this exciting and creative camp-themed park which includes water slides, a toddler pool, lazy river and more amenities for all ages. MEG was specified as the architects were looking for wood effect cladding which would complement the camp theme and which could be cut into planks to simulate a cabin.

It was also heavy duty enough to cope with the sustained usage and the extremes of sunlight and temperatures which can easily range between -2°C in the winter and 35°C in the summer. As a result, MEG 754 Padouk was seen as the perfect solution. This visual plank look can now also be achieved with the

newly-launched and competitively-priced Easy MEG siding product.

Camp Cohen is another example of MEG in action where the need for high performance and durability is married up with low life-cycle costs, aesthetic design and resistance to weathering. The range comprises 58 colours and 29 woodgrains together with 5 concrete and metal effect finishes. MEG is a self-supporting high pressure laminate (HPL) for cladding the exterior of buildings, balconies and other applications.

It features high resistance to temperature, climate shock, weathering, UV light and impact. Samples and technical literature are available from Abet Ltd on tel: 020 7473 6910 or visit uk.abetlaminati.com

MAGPLY FEATURES IN FIRE-FIGHTING ROLE AT SKY STUDIOS ELSTREE Magply boards are being used as part of Sky’s efforts to create the world’s most sustainable film and TV Studios, Sky Studios Elstree. Currently under construction by main contractor BAM, the build has recently included the use of 9mm thick Magply boards as part of a flat roof build up specified for the product’s proven fire-protection capabilities and allround performance benefits.

The work on the new production buildings is being carried out by London based Waterproofing specialist, Guaranteed Asphalt Ltd. which is installing their BBA Agrement certified hot melt flat roofing system over a reinforced concrete deck with the Magply boards being used to protect the mineral wool insulation. The Magply boards were secured in place over the 300mm thick StoneWool insulation using an adjustable length TIA fixing from the SFS range: drilling down into the concrete substrate. The fixing consists of a mushroom-type plastic sleeve which inserts in the bore hole, followed by a secondary concrete screw that is dropped into the sleeve, which is driven into the deck.

Magply MgO boards present a fire-safe and environmentally friendly alternative to conventional plywood or OSB products. The different thicknesses of panel are also widely used for flooring and pitched roof installations as well as being approved by many different manufacturers of render finishes as a suitable substrate. www.magply.co.uk

Public Realm Regeneration With Permeable Paving A new case study explores recent urban realm regeneration projects in Tottenham, London exemplifying the synergy of concrete block permeable paving and street trees to address climate change while delivering SuDS. It demonstrates important new techniques with permeable surfaces applicable to all urban areas. Completed in 2018, the regeneration of White Hart Lane in north Tottenham, by muf architecture/ art, was a pilot designed using ‘Healthy Streets’ principles.

These aim to create: ‘streets that feel pleasant, safe and attractive. Streets where noise, air pollution, accessibility and lack of seating and shelter are not barriers … streets with seating, shade and greenery, and reduced dominance of vehicles by designing for slower vehicle speeds.’ The project delivers these aspirations and was one of the first to use the ‘Healthy Streets’ indicator as a metric.

Multifunctional Permeable Paving - But it also applies innovative sustainable drainage (SuDS) techniques introduced by design collaborators Robert Bray Associates. This approach reduces flooding and pollution of the hidden Moselle River through the integration of bioretention raingardens to collect and treat polluted road runoff. In addition, extensive concrete block

54

permeable paving (CBPP) surfaces not only act as SuDS elements – attenuating and treating rainwater runoff – but also enable essential air/CO 2 exchange and optimised water supply for tree roots, using a range of techniques. A focal point of the scheme is a new Pocket Park, enabled by relocation of a bus stop and removal of extensive asphalt paving.

The park is separated from the road by bioretention raingardens, intercepting runoff from the whole width of the ‘side-hung’ carriageway which acts as a catchment. It also includes long planters to accommodate mature and new trees, and other green infrastructure, incorporating seating. This also enabled de-paving around a mature but suffocated and asphalt-locked Plane tree.

Love Lane, which runs perpendicular to White Hart Lane in front of the new landmark Underground station, is now a concrete block permeable paved, adopted highway.

CBPP can also accept runoff from White Hart Lane and other impermeable surfaces. At two points, structural tree pits span the full width below the road surface connecting road-narrowing tree planters on each side, in readiness for future planting.

Based on the ‘Stockholm Solution’ for urban tree planting, the deep structural soil zones form sumps which are hydraulically connected to the coarse graded aggregate sub-base of the permeable paving.

it to the tree. It can then simply discharge horizontally into a raingarden, with overflow into existing adapted gulleys. The raingarden stores water during heavy rain for SuDS, retains soil moisture during dry weather and provides additional water quality ‘polishing’, as well as irrigation.

Alternatively, CBPP can be used over standard tree pits, proprietary tree planters, Stockholm System or other structural soil installations, enabling irrigation and simple air/carbon dioxide exchange essential to trees – without additional

Healthier Resilient Street Trees - This means that in heavy or prolonged rain, once percolated runoff begins to move laterally along the interface between the sub-base and subgrade, it moves toward the structural tree pits where it begins to be attenuated. Once the pits fill to the level of the base of the road sub-base, the attenuation and infiltration spread out over the whole road zone.

This pattern of flow and attenuation means that trees benefit from rainwater collected from an extended catchment, making them healthier and more resilient to drought. Although initially unfamiliar with the structural tree pits, with support and advice the installation contractors soon became comfortable and are now installing them elsewhere.

At the renovation of Broad Lane Square in south Tottenham, the same designers take forward these principles with further innovations. In particular, ‘inverted raingardens’ protect existing trees and new green infrastructure, supplied with a gradual supply of clean water from extensive CBPP catchments.

reservoirs or pipes. CBPP also avoids tree root disruption common with other paved surfaces. Concrete block permeable paving technology will prove invaluable in delivering the street trees now demanded by planning policies for new developments as well as regeneration.

so that the slices close together. Even tighter radii can be achieved by folding the boards so that the ‘teeth’ open up.

They can either be fixed against a blockwork of other solid surface using a continuous coating of tile cement or secured to timber battens at 300mm centres using screws and the special Marmox washers. This flexibility makes Curved Multiboards ideal for creating archways, curving partitions and cubicles or even moulded tiled seats. www.marmox.co.uk

The acoustic performance of a major London landmark building was upgraded using the StoSilent Distance acoustic system. Hayward Gallery at London’s Southbank Centre underwent a complete refurbishment, and the StoSilent Distance system helped create a new and dramatically improved acoustic environment for this worldrenowned art gallery.

The 66 pyramid-shaped skylights which originally featured on the building had become damaged over time, while internally, a series of impractical sound-absorbing baffles and a translucent suspended ceiling had been used below them. The aim was to remove the suspended ceiling, reclaim the original height of the gallery spaces, and allow more natural light to enter. The pyramid roof lights were reconstructed using modern materials, and this meant that reliable acoustic treatment needed to be fitted into the coffer spaces below them in order to create the required acoustic environment.

Unlike conventional acoustic treatments which use exposed grid and tile systems and offer limited design possibilities, the StoSilent Distance solution allows the creation of modern, clean, monolithic and seamless solutions, and can accommodate unusual design features such as the gallery ceiling and its pyramid-shaped skylights. StoSilent Distance was installed in the deep acoustic coffers which sit below each of the pyramid skylights. www.sto.co.uk

AFFORDABLE HOUSING GIVEN SUPERIOR VAPOUR BARRIER AND AIRTIGHTNESS SOLUTION A series of 10 newly built affordable Council houses in Montrose, Scotland has been fitted with a highperforming variable-permeability vapour control layer from the A. Proctor Group. Procheck® Adapt is designed to protect the building fabric from the potential risks of condensation and act as an effective airtight barrier.

Contractor, Andrew Shepherd Construction, proposed the use of the Procheck Adapt available from the A. Proctor Group. Thanks to its unique design, the Procheck Adapt membrane offers variable permeability which adapts to changes in humidity levels and allows the structure to dry out in the summer and in sunny days during spring and autumn while protecting it from moisture overload in the winter. This is possible because the membrane adapts its vapour resistance to the environment i.e., vapour tight in the winter and more vapour open in the summer.

This ensures that the building fabric is protected from damaging moisture levels during cold, wet winter months, and allows the fabric to dry out effectively in warmer, drier months. Procheck Adapt has a translucent structure which eases fixing to structural frames and in combination with its integral tape allows for a fast installation time. Procheck Adapt is suitable for a variety of commercial and residential applications and provides airtightness to the structure as well as vapour control. www.proctorgroup.com

Major Innovative New Solution From The Ever Progressive Schöck Over six decades Schöck has built a formidable international reputation for innovative and progressive product design. The company is best known for its market leading range of Isokorb structural thermal breaks, but its pioneering reinforcement technology and impact sound insulation solutions are also a significant part of the product portfolio.

Innovation though is not always about original product development. The Schöck philosophy of rethinking existing product capabilities can lead to derivative technology and the new Sconnex product range is a perfect example. It offers outstanding insulation performance, combined with an exceptional load-bearing capacity.

Closing the last major thermal bridge - Type W, for insulating the thermal bridge at the base, or the top of the reinforced concrete wall; type P for insulating the column head and eliminating the need for flank insulation; and type M, a capillary barrier that insulates at the base, or the top, of a masonry wall.

With these ingenious high quality solutions, the company has transferred its Isokorb expertise in balcony technology to walls and columns. But what necessary development steps and which building physics obstacles had to be overcome for the concept to become an approved component?

PROJECT INSIGHT

Building physics and expert analysis - The main focus of the 2050 building policy guidelines is to reduce energy losses and a critical area is the thermal performance of the building envelope, through a fabric first approach.

Sconnex contributes significantly to meeting such a challenging and vital sustainable concept. About 40% of all thermal bridges in a building are caused by walls and columns, resulting in around 10% of heating energy losses. So the objective was to be the first company to develop a component for wall and column connections that both minimises thermal bridges and makes external insulation unnecessary.

However, bringing a major new product to market requires extensive due diligence. First, building physics analysis confirmed the solution as being realistic in its practical implementation. Then, extensive expert opinions were prepared for the German Institute for Construction Technology (DIBt), where all mandatory legal requirements, including 90 minute fire resistance, were met. Because of the variance from practiced construction methods, Schöck also involved scientists from the University of Darmstadt.

With groundbreaking innovations, Schöck often teams with specialists from universities and high-profile engineering firms in the development of calculation models. In one dissertation, an empirical design proposal was created for the application of the connection element in construction practice, based on extensive experimental studies on its load-bearing behaviour. Schöck test results were also incorporated and the design proposal ratified by expert opinion.

Sto’s External Wall Insulation System And High-Performance Façade Paint Help Bring New Innovation Studio To Life A new state-of-the-art business incubation building in Dorset has been completed with the use of an integrated package of Sto thermal insulation and external render and paint products. The company’s StoTherm Vario and StoTherm Classic insulation systems were specified for the new Innovation Studio at the Arts University Bournemouth, along with StoSilco exterior render and StoColor Dryonic façade paint.

The new Innovation Studio now provides a base for digital and creative start-up businesses, providing support with their research, innovation and development initiatives. “This is an important building, part-funded by the Dorset LEP,” explains Tim Culverhouse of project architects, CRAB Studio. “It needed to combine a very specific mix of internal facilities with a modern, dramatic, external appearance that reflected the creative nature of the occupants.”

60

The cost-effective StoTherm Vario system installed onto this unique two-storey building has an efficient single-leaf construction that provides excellent thermal performance whilst also protecting the external wall surface from weathering.

A mineral bonding and reinforcing mortar was used to adhesively fix the insulation to the cement particle boards and lightweight steel frame, and the system was able to accommodate the curved substrates which feature in the building’s design. Although an alternative insulation system was originally considered, it was decided that Sto solutions could provide the same thermal performance, but also deliver cost benefits.

PROJECT INSIGHT

StoTherm Classic K insulation was also specified for certain parts of the building. “We needed a different solution for some areas,” adds Tim Culverhouse.

“These sections carry painted murals, and we wanted those to extend right down to the bottom of the walls, so the insulation had to extend down below the damp-proof course."

"The StoTherm Classic K was perfect for this. It didn’t require any additional expansion joints, and so created a smooth surface onto which the murals could eventually be added. The murals now appear to ‘flow’ down into the ground and create a striking visual effect.”

A reinforcing coat with embedded reinforcing mesh was applied to the insulation, followed by the StoSilco K1.0 silicone resin render, to add extra protection.

This genuine silicone resin-based render is robust, durable and provides a very high

degree of CO2 and water vapour permeability, to reduce the risk of interstitial condensation. The overall external façade system was completed with the application of Sto’s innovative StoColor Dryonic façade paint in yellow and orange shades.

This unique paint uses principles borrowed from nature to create a surface which simultaneously repels water and channels it away, to encourage the surface to dry more rapidly and protect against the growth of algae and unsightly staining. The façade will look exactly the way the architect had planned, and will go on looking that way for many years to come, with far less maintenance than any conventional alternative would require. www.sto.uk

Cupa Pizarras Supplies Contemporary Rainscreen Cladding Solution For Impressive London Home CUPA PIZARRAS has been heavily involved in the development of a new self-build residential property in North West London. The manufacturer was initially approached due to its range of natural slate façade designs, with its CUPACLAD® 201 Vanguard system eventually specified to create an impressive and striking façade. Located in Dollis Hill, the property is situated next to a housing estate and opposite an existing slate clad façade, while views to the rear give the illusion of a peaceful woodland setting.

The designers sought to create a family home with a high-end exterior finish that felt like an escape from London, while also working well with the surrounding structures. Early on, natural slate was identified as a material that could help to create an attractive contemporary façade around the rear, sides and the upper elevation of the front of the property. It was also crucial that the façade would act as a rainscreen cladding system so the project team approached CUPA PIZARRAS about its CUPACLAD® natural slate rainscreen cladding.

The project team visited Taylor Maxwell’s London Bridge showroom – the exclusive distributor of CUPACLAD® in the UK - to discuss options with the Taylor Maxwell and CUPA PIZARRAS teams as well as view a CUPACLAD® sample wall. This session helped to establish that the CUPACLAD® 201 Vanguard system was the ideal solution. A fully BBA approved system, CUPACLAD® 201 Vanguard is 100% non-combustible and offers a lifespan of over 100 years.

Following the initial consultation, CUPA PIZARRAS worked closely with the project team, including carrying out a number of site visits.

62

PROJECT INSIGHT

The use of CUPACLAD® 201 Vanguard was kept in mind throughout the design process, with the dimensions of the slate determining the placement of windows, vents and corners. This meant that when it came to construction, it was a simple installation process with minimal wastage and resulting in a clean finish.

The CUPACLAD® 201 Vanguard system is constructed from horizontal aluminium profiles, mechanically fastened to an aluminium sub frame support. Once fixed in place, the rows of natural slate are clipped on, and in the case of the Dollis Hill property, using visible fixings to create an attractive pinstripe effect.

“The product looks fantastic in-situ on this project,” commented Tom Ward, Cladding Product Advisor at Taylor Maxwell.

One hundred metres of Hauraton RECYFIX® PRO 100 channel system, fitted with FIBRETEC® C250, 9mm HEELSAFE slot gratings, was used by groundwork subcontractor GPB Construction Ltd to drain the asphalted Blue Badge parking bays for visitors. The channels were installed between the bays and the path leading to the entrance of the new arrivals hall.

The material, PA-GF used to make the FIBRETEC® grating, was especially developed by Hauraton; the tough, UV resistant, fibre reinforced moulding offers high stability and huge strength for its weight. Complying with loading category Class C250 (BSEN 1433) the grating can easily take the weight of cars and commercial delivery vehicles.

The FIBRETEC® C250 HEELSAFE slot grating was specifically designed by Hauraton R&D engineers to enhance the flow of water into the channel. The slots are super smooth, elliptical openings with the moulded bars having slightly raised triangular bosses along their outside edges.

As well as providing an elegant appearance, the feature ensures surface water is directed into the slots. This configuration also helps eliminate any cross-flow over the grating.

The RECYFIX® PRO 100 channel component is made from 100% recycled polypropylene (PP). The six sizes offered are 160mm wide and range in height from 75mm to 250mm with the FIBRETEC® grating factory fitted on all models. As the largest unit is only 5.8kg, the channelling is easily handled and quickly installed on site. www.drainage-projects.co.uk

The design is a real innovation as its non-corrosive material provides a visually appealing surface finish that retains its black colour.

The Sky Is The Limit For The Riverside Museum, Glasgow, With The Help Of Bilco UK Housing the Glasgow Museum of Transport, one of the UK’s foremost transport and technology collections, the Riverside Museum reflects Glasgow’s historic role as a centre of shipbuilding, train manufacturing and engineering. Previously located in a former tram depot on the Glasgow South Side, the Transport Museum’s exhibits have moved to The Riverside Museum, designed by renowned architect, Zaha Hadid.

distinctive roof. Expertly engineered to meet the requirements of Manual Handling Regulations, the E-50TB Roof Access Hatch allows for regular and convenient maintenance by facilitating easy one-handed operation.

The museum’s iconic and beautiful design dominates its riverside location, whilst paying homage to the heritage of its surroundings.

Crucial to the museum’s flowing design is its roof, which curves and undulates and continues around the east and west sides of the building to constitute the majority of the external structure. Silver-grey zinc panels complete the effect, placing the building firmly in the context of the River Clyde.

Specified to ensure strict adherence with relevant fire safety regulations, the two ESW-50REM Smoke Vents open to 140 degrees in the event of a fire within 60 seconds, guaranteeing the highest standards in fire safety and allowing for the venting of smoke, heat and noxious gases in the event of a fire. Open to Glasgow to the North and the Clyde to the South, the museum’s interior is complex, inviting visitors to snake their way around the various exhibits. www.bilcouk.co.uk

As part of the roof construction, Bilco UK was commissioned to manufacture and supply a E-50TB Roof Access Hatch, in addition to two ESW-50REM Smoke Vents, to meet strict requirements for convenient access and building safety regulations. Both the roof access hatch and smoke vents were custom-designed to unique specifications by Bilco UK’s in house team and clad in zinc to create a seamless, aesthetic finish with the museum’s

Howe Green On The Right Track With Crossrail Contractor, DMC Contracts

As Europe’s largest current infrastructure project, spanning over 60 miles via 41 different stations, the Elizabeth line will transform rail transport for London, with annual expected passenger levels reaching 200 million. The landmark project has seen the construction of 42km of new tunnels and the development of 10 new stations, with 31 existing stations also undergoing extensive upgrades.

As part of the formation of the central line, which spans from Westbourne Park to Plumstead and Pudding Mill Lane, official Crossrail contractor and one of the UK’s leading fit-out contractors, DMC Contracts, has installed over 1,500 Howe Green Floor Access Covers throughout seven stations. This includes Whitechapel, Farringdon, Paddington, Bond Street, West Ealing, Ealing Broadway and Acton Mainline, where over the last five years DMC Contract’s team of engineers have also installed over 30,000 square metres of Terrazzo and Granazzo floor tiles.

Howe Green’s 7500 Series stainless steel Floor Access Covers have been installed throughout the ticket halls, walkways and main concourses of each station to provide engineers with secure and concealed access to under-floor services, whilst the tamper proof construction also prevents unauthorised access. This is due to the cover’s unique design, which features unobtrusive barrel

cover lifting points that can only be accessed with specific lifting and securing keys. As only the securing bolt and barrel edge are visible, the covers provide the highest standards of security, without impacting on the overall design scheme or presenting a potential trip hazard.

Manufactured to BS 476: Part 22, the 7500 Series provides resistance to fire and smoke for up to two hours, providing the highest standards in safety, performance and compliance throughout all seven stations. With each floor access cover withstanding up to five tonne pneumatic tyre wheel loads, the 7500 Series was also supplied in a range of configurations, including singles, multiparts and ducts, to provide unobstructed access to rodding points and winch systems and electrical pits throughout all areas of the stations.

As the lifting blocks are anchored to the inner frame, the floor access covers can be handled easily and safely by contractors, reducing any potential disruption to passenger’s travel as the maintenance can be conducted quickly and safely. www.howegreen.com

High Praise For SureSet Walkways At Chapel Riverside Located on the River Itchen, sits Chapel Riverside, where a new housing development started in 2017. There are six phases to include 457 new homes which will be built near to the Ocean Cruise terminal. The project was approved by Southampton City Council and is now into the third phase comprising of 132 apartments, all with allocated parking and premium specifications that run alongside the Solent Sea Wall.

Southampton City Council had a clear vision of what they wanted to achieve and were determined to have the whole walkway paved in the most economic, cost effective, durable and aesthetically pleasing product possible.

They appointed multi award–winning specialist housebuilder and brownfield developer Inland Homes as main

70

contractor. SureSet were contacted by Kain Dear, the Senior Site Manager from Inland Homes, to attend a pre contract meeting. SureSet were able to provide the requested large resin bound sample panels with various colour options so they could view the paving against the Sea Wall and determine the best appearance.

The SureSet team was also able to discuss the benefits of the products, installation methods and advise on the suitability that the resin bound paving would offer to the walkways. One of the seven key areas in this project was to re-shape the landscapes of the city.

To achieve a consistent aesthetic across the phases of Chapel Riverside Developments, the same materials were to be used throughout.

PROJECT INSIGHT

The colour chosen was 6mm Butterscotch, a permeable resin bound paving material from SureSet's Natural Aggregate range, installed at an 18mm depth. This product was laid to create a desirable waterfront, and due to the smooth nature of the compacted surface, it is suitable for the moderate to high foot traffic and accessible pathways. The area was built above ground level for the apartments and accompanying landscapes to improve ground floor access and create new walkways around the buildings to ensure everyone can enjoy the views.

The work Inland Homes have achieved will further promote investment in Southampton. The 360m2 resin bound paving installation was completed over two days, the asphalt and concrete areas were quality checked and dip tested prior to installation. SureSet ensure that their bases are prepared to safeguard longevity.

These pathways were no exception and using a primer and crack reduction membrane over the concrete areas will minimise movement cracks.

finished by more traditional hand floating.

The SureSet paving looks clean and smooth having the added benefits being low maintenance and permeable. Chapel Riverside has a mix of building types and has been transformed with a new public piazza with cafes, restaurants and shops as well as spaces for retained and enhanced marine industry and activities.

The resin bound walkways are surrounded by green lawns, and seating areas to soak up the views. The 300m stretch of river flood defences, and the reconstruction of a new underground surface water storage tank for Southern Water also makes for an economical build.

Chapel Riverside in Southampton is already a home for many residents and is seen to be a new destination for modern waterside living, and an integral grand plan for economic growth and development within Southampton City.

A sleek stainless steel edging, supplied

by Dural Ltd, was carefully secured to the areas as advised on the plans provided.

SureSet's installation comprised various methods. The first was to level out the resin bound material by batch - this was efficiently compacted by using mechanical power floating, and the edges were

MARMOX THERMOBLOCKS CUTTING CARBON FOR SOCIAL HOUSING RESIDENTS Work is well underway on the first phase of an affordable housing project for Somerset West and Taunton Council, where the use of Marmox Thermoblocks was put forward by specialist developer, Equans Regeneration which is leading the work on the site in Taunton. Phase A of North Taunton Woolaway Project will see the construction of 47 new one, two and three bedroom properties with energy saving and the reduction of environmental impact both being given full consideration.

The issue of thermal bridging, in particular, is being addressed through the decision to utilise the highly insulating Thermoblocks around the perimeter of the ground floor slabs. With over 200 homes to be built in the next few years, the total number of Thermoblocks required will run into the thousands. Each length of Thermoblock is comprised of ultra-high performance XPS insulation, encapsulating miniature epoxy concrete columns, while the top and bottom are covered by alkali resistant glass-fibre mesh, retaining a surface of fibre reinforced polymer concrete to facilitate bonding.

The concrete columns have a very low conductivity, so do not present thermal bridges themselves and when coupled with the highly insulating XPS insulation core, a combined thermal conductivity of 0.47W/mK is achieved. Crucially, being able to employ a defined, very low thermal transmittance – derived by thermal modelling or measurement – offers a far more advantageous result than adopting the ‘default’ figure offered in SAP, which can often result in non-compliance under Part L. www.marmox.co.uk

FIREFLY™ APOLLO LITE CREATING HALF HOUR FIRE BARRIERS IN NEW RESEARCH BUILDING A specialist contractor undertaking all of the fireproofing within a new medical research building in Surrey has been making use of two well proven, flexible fire barrier products from the TBA’s FIREFLY™ range, to provide 30 minutes protection within the majority of the ceiling voids throughout the four-storey structure. CLM Fireproofing has established a reputation as a leader in the fields of both passive fire protection and fire-stopping. CLM is employing Apollo Lite and the Collaroll product in tandem to protect the ceiling voids. The spaces which typically house pipework, power cables and air conditioning units above the suspended ceiling grid, are provided with 30 minutes integrity and insulation through the installation of the flexible Apollo Lite barrier.

The Apollo Lite 30/30 has been developed for use in vertical separation or compartmentation situations, offering both 30 minutes integrity and insulation, thereby exceeding the minimum requirements of the Building Regulations. It is widely specified to form fire barriers within roof voids in many different property types.The flexible woven material is easy to cut and fix and is chemically treated to improve its cooling properties, and therefore prevent temperatures rising in adjoining areas. The system has been fully tested to BS 476 Parts 6.7, 20 & 22 and is third party certified by IFCC. www.tbafirefly.com

Hauraton Drainage Systems At Bonus Arena - Hull Venue Built on brown-field land located on the edge of the main shopping district in Hull and adjacent to Princes Quay, the Bonus Arena – Hull Venue and its associated multi storey car park were opened in August 2018. The £36 million development progresses the legacy of the social and economic impact generated by Hull’s 2017 UK City of Culture status. The Arena, designed

by AFL Architects, is a state-of-the-art music and events complex with a flexible capacity of up to 3,500 people. The facility can provide a venue for concerts or corporate conferences in an 800 seat auditorium.

A 2000m² adaptable space can be utilised for sporting events or exhibitions and trade shows.

Surrounding the Bonus Arena is a public realm laid with grey stone paving and landscaped by reform Landscape Architecture Limited with trees, lawns, flowerbeds and permanent stone seating.

An effective surface water drainage system was essential to ensure all weather access to the venue. 140 metres of Hauraton RECYFIX® PRO 100 channels with FIBRETEC® heel-safe gratings were chosen for the job which blended well with

74

the stone paving and would resist damage from applied grit rock salt in freezing weather. The material, PA-GF used to make the FIBRETEC® grating, was specially developed by Hauraton; the tough, UV resistant, fibre reinforced moulding offers high stability and huge strength for its weight. Complying with loading category Class C250 (BSEN 1433) the grating can easily take the weight of commercial delivery vehicles.

The design is a real innovation as its noncorrosive material provides a visually appealing surface finish that retains its colour. The slots are super smooth, elliptical openings with the moulded bars having slightly raised triangular bosses along their outside edges. As well as providing an elegant appearance, the feature ensures surface water is directed into the slots.

The RECYFIX® channel component is made from 100% recycled PP. The PRO 100 model is factory fitted with the FIBRETEC® grating and only weighs 4.6kg, so the unit was easy to handle and quickly installed on site. www.drainage-projects.co.uk

CUT-TO-FALLS MULTIBOARD HELPS DRAIN TOP FLOOR BALCONY An experienced builder and roofing contractor has made use of some 300 standard and tapered Marmox Multiboards to complete a complex refurbishment of a large, top floor balcony on an apartment building in North London. Lightwood Construction carries out work for mainly residential clients right across the capital and has used Marmox Multiboards on many occasions in the past for both interior and exterior applications.

In this instance, long term exposure to the weather and ponding had caused the original waterproofing system to deteriorate, and leaks to occur. Having stripped off all of the rotten felt and boarding, Lightwood Construction’s operatives installed 90 sheets of 20mm thick standard Multiboards, along with 200 of the cutto-falls variant enabling subtle gradients to be created in draining the balcony to multiple outlets.

Equally suitable for wet room applications, Marmox’s Sloping Boards are made from the same waterproofing products as Multiboard - thermally insulating XPS sandwiched between two layers of Marmox’s patented polymer-concrete. The boards have undergone rigorous tests to ensure they are suitable for external use so can be used on the most exposed balconies, as well as inside a wet room. The board is produced in just one size, 1200 x 1200mm, with the edge thickness tapering from 33mm down to 10mm at the opposite side. They can be combined with layers of 20mm thick Marmox Multiboard to extend the slope indefinitely. www.marmox.co.uk
