Daylighting fit for Kings

Recent redevelopment of the food court at Kings Mall Shopping centre, on a five-acre site in London’s Hammersmith area, exposed up some interesting and complex challenges.

As part of the ongoing development, the new residential apartments above the shopping centre were being adversely affected by light pollution and lack of privacy from visitors looking through the food court atrium.

To solve this problem, owners and developers Schroders decided to install Kalwall translucent cladding around the whole of the atrium. This screened the external courtyard above, thereby mitigating the issues around privacy, while maintaining the maximum levels of interior daylight.

Installed in a Verti-Kal pattern, the Kalwall panels complement the industrial feel of the redevelopment and its hard concrete and stone surfaces, while providing several benefits for shoppers and residents alike.

This project perfectly illustrates the advantages of Kalwall over traditional glazing. Here it offers complete line-of-sight protection, maintaining privacy for the residents and controlling light pollution, while bathing the interior with diffused daylighting, regardless of the weather. The panels are lightweight but very durable with excellent resistance to impact and scratching. They are also vandal resistant with good protection against windborne debris.

In addition, Kalwall’s insulating properties mean that U-values down to 0.28 can be achieved while daylight is driven deeper into the interior space below, thereby reducing energy costs for both artificial lighting and temperature control.

The exterior face is colour stable and includes a UV resistant, self-cleaning surface. This means that normal rainfall helps to keep the surface free of dust and dirt while at the same time retaining the original colour during the weathering process. All this helps to reduce the costs of maintenance and cleaning.

Passivhaus Estate constructed with Kingspan TEK

The Kingspan TEK Building System is providing a precise offsite building solution for one of the country’s largest Passivhaus developments in Bowthorpe, Norwich.

Rayne Park is the first development by Norwich Regeneration Company, wholly owned by Norwich City Council, and will include a mixture of private and affordable housing. RG Carter are constructing 112 of the 172 properties on the development to the Passivhaus Standard. The internationally renowned energy efficiency standard requires buildings to be both highly insulated and airtight.

After reviewing the market offering to achieve the demanding fabric requirements of the Passivhaus Standard, it was concluded that the Kingspan TEK Building System was the best solution for the project on the basis of technical specification and value offered.

Kingspan TEK structural insulated panels (SIPs) feature a high-performance insulation core sandwiched between two layers of OSB/3. The panels were fabricated to the site’s requirements by Kingspan TEK Delivery Partner, Kingspan Timber Solutions. This offsite fabrication process allowed the panels to be factory cut to the specific design requirements, minimising waste and allowing an accurate, fast-track erection process on site.

Kingspan TEK Building System panels can achieve U-values of 0.20 – 0.17 W/m2.K, or better ‘out of the box’. With the addition of an additional layer of insulation, the site team were able to further improve the thermal performance of the external walls – achieving a final external wall U-value as low as 0.09 W/m2.K.

The panels’ proprietary jointing system not only allows continuity of insulation at junctions but, in combination with the OSB/3 facings, also helps to create highly airtight buildings. Once the outer shell was erected, RG Carter installed an additional internal membrane and applied airtight tape to all joints, resulting in a final air leakage rate of from 0.37 to 0.56 air changes per hour @ 50 Pa. This highly airtight design necessitates the use of a mechanical ventilation heat recovery system (MVHR) to maintain a constant supply of fresh air within the properties. MVHR units use the heat from outgoing stale air to warm incoming fresh air, further reducing the property’s heating demand and creating a fresh and comfortable indoor environment.

It is expected that the properties will have a heating demand of just 11 kWh/m2a and a primary energy requirement pf 77 kWh/m2a. This heating demand is around 10% of that of an average home (estimated to be 140 kWh/m2/yr ), making them both cheap to run and comfortable to live in.

Sika concrete repair solution rises to challenge of tower block refurb

Sika supplied the corrosion-resistant repair solution as part of a huge refurbishment involving six social housing tower blocks.

The Brentford Towers in west London form an imposing cluster in an estate within the capital’s Hounslow district. Built between 1968 and 1978, the towers contain 88 homes in each of 6 twenty four storey point blocks with exciting views over the Thames and West London. Over time, the structures’ concrete façade had become cracked and spalled in areas, leading to Hounslow Council implementing a repairs programme as part of a major overhaul of the buildings.

UK Gunite was selected to apply the Sika repair system on behalf of the project’s main contractor, Engie UK. With work starting in 2017, it initially involved applying Sika® FerroGard®-903+, a surface-applied mixed corrosion inhibitor. This ingenious solution, which is based on organic compounds, is designed for use as an impregnation of steel- reinforced concrete. It is spray-applied and penetrates concrete to form a protective monomolecular layer on the surface of the reinforcing steel, thus delaying the corrosive process and the rate it progresses.

Surface cracks and spalling were then repaired using Sikagard®-545 W Elastofill. This quality product provides a crack-bridging intermediate coat, which closes pores, cavities and blowholes. It also offers excellent resistance to water ingress and damp. Sikagard®-550 W Elastic provided the concrete surface’s crack-bridging protective coating. Class ‘O’ fire-rated, Sikagard®-550 W Elastic the product is particularly ideal for exposed concrete structures susceptible to cracks and openings and the like. For the Brentford Towers refurbishment, Sika’s repair and corrosion protection solution was used across a surface area covering 25,000m².

John Dorling at Engie, said: “This was a huge project to undertake. Therefore, we required a concrete repair and protection system that was proven to be effective over large areas. The spray-applied Sika® FerroGard®-903+ was not only the best solution in terms of the protection it offered, it was also the most time and cost-effective, as its penetrative properties negated the need to break-out large areas of concrete. The Sikagard®-545 W Elastofill was also a revelation in terms of its crack-bridging ability and the light-grey finish it provided.”

Cllr Lily Bath, Cabinet Member for Housing and Social Inclusion, Hounslow Council, said “We are excited to be working with Sika, Engie and other suppliers to repair and return these iconic buildings to the landmark status that they have in West London, and to a condition that our residents deserve.”

By specifying Sika’s concrete repair and corrosion protection system, the project’s clients, Hounslow Council, have a 15-year guarantee on work involving large areas of concrete with carbonation beyond the depth of the reinforcement. Therefore, the structural integrity of these striking tower blocks has been future-proofed for the reassurance of client and occupants.

York Hospital again chooses Rinnai hot water heating units for upgrade

Clifton Park Hospital in York, advised by A J Gastech – has chosen Rinnai to upgrade its hot water heating system to meet the increasing demand whilst staying economically and environmentally efficient.

Clifton Park Hospital opened in 2006 has first-class medical facilities including 24 beds, two theatres, a day case unit, a large outpatient department with X-ray facilities and on-site physiotherapy, including a small gym area. In 2018, the hospital opened a new outpatient department with 11 consulting rooms, two treatment rooms and x-ray facilities.

Clifton Park prides itself on offering exceptional care and service to all its patients and currently has a 5 star rating on NHS Choices, 4 star rating on Google and 4.7 rating on Facebook reviews. In the most recent survey – NHS Family & Friend’s Test, 100% of inpatients and 98% of outpatients recommend the hospital.

The new water heating system features 3 Rinnai HDC 1200i plus a 500 litre cylinder. A Rinnai HD50i looked after the hot water demand for 10 years, without missing a beat, but due to expansion at the hospital a new bespoke system was required.

The decision was taken to upgrade to more energy efficient condensing hot water heaters and incorporate the 500 litre storage vessel to give the hospital a means of dealing with peak hour demands.

The heating engineer contractors, A J Gastech, were given just a 14 hour window in which to remove the existing system and replace it with the new one. This was achieved with a bit of time to spare, such is the expertise and professionalism of A J Gastech.

A J Gastec Ltd provide plumbing and mechanical contracting and maintenance for private customers, construction organisations in domestic, commercial and industrial sectors. The company offers services from installation to maintenance contracts with the variety of works involving sites throughout the UK for both public and private sector works.

Says Adam Stante for A J Gastech, “We are based in Bradford, the heart of Yorkshire, and we have a dedicated team of specialists that work throughout the UK, delivering high spec projects on time and on budget. Our standards are of the highest quality, cost effectiveness and to our client’s approval.”

The Rinnai HDC 1200i continuous model is for use on all high demand sites as it is easily capable of delivering 2000 litres per hour. It guarantees unparalleled levels of efficiency and hot water delivery for the end user whilst streamlining installations and guaranteeing future regulatory compliance.

This is a precision engineered water heating unit can also be combined as multiple units into one single, easy to handle module. Both HDC1200 internal and external models turn in a market leading energy performance of 107% net efficiency and offer superlative ranges of modulation as the system’s internal analytical system can modulate the burner range from 54kw to 2.4kw. The Rinnai HDC 1200i is engineered for minimal energy wastage and maximum energy performance.

It is worth remembering that Part L of the Building Regulations 2013 set minimum thermal efficiency levels of 90% for natural and 92% for LPG, consequently outlawing non-condensing gas fired water heaters for use in new build projects.

Rinnai units and systems are now the number one choice for large buildings and businesses with a heavy demand for constant hot water or where high peaks of demand occur at certain times. Any number of modules can be manifolded, so the water handling capacity is truly infinite and there is no risk of the ‘cascade’ of hot water ever running out.

The manifolded 1200i units can be delivered direct to site in one complete, easy to manage package and at a very competitive price. For the end user this guarantees considerable cost savings over other forms of hot water generation. The relatively compact footprint of all Rinnai units and systems means it can optimise plant room space and safeguard accessibility for maintenance and servicing.

There is huge potential for on-demand style water heaters such as the Rinnai HDC 1200i units to play their part in new build and in refurbishments where there are still many old systems that need replacing as well as old-style gravity fed water systems that use stored hot water.

The Rinnai Infinity HDC 1200i has lower greenhouse emissions because of the new reduced NOx burner technology.

As Clifton Park Hospital has a secondary flow and return system, complete range modulation is experienced ensuring that the system is running at optimum performance at all times.

Creating a community with Kingspan TEK

Kingspan TEK Cladding Panels have provided an offsite wall solution for a unique school and leisure campus in Littleport, helping the project to achieve excellent thermal performance within a tight construction deadline.

The £37.5 million development, designed by SNC-Lavalin’s Atkins business, co-locates a pre-school, Littleport and East Cambridgeshire Academy (LECA), Highfield Littleport Academy Special Education Needs (SEN) school and a public leisure centre. It has helped to create an inclusive community where children of all ages and abilities can develop together. To ensure the ambitious plan would be delivered in time for the new school year without compromising on the facilities’ energy performance, 142 mm-thick Kingspan TEK Cladding Panels were specified for many of the external walls.

Kingspan TEK Structural Insulated Panels (SIPs) were designed and factory cut to the project’s unique specifications by Kingspan Timber Solutions. This offsite production process minimised site waste and enabled the panels to be quickly installed onto the steel frame, ready for main contractors, Morgan Sindall Construction, to apply the final external finishes.

The highly-insulated core of the Kingspan TEK Cladding Panels allowed the project to meet its thermal performance targets. Meanwhile, the OSB/3 facing and unique jointing system minimised air-leakage through the building envelope, helping the scheme achieve a BREEAM ‘Very Good’ rating. In addition to supporting a fabric first approach and limiting the heating demand, the product’s excellent thermal performance also helped to keep wall constructions to a minimum depth, maximising the useable space within.

This was Morgan Sindall Construction’s first project implementing BIM design methods up to level 2 compliance. Utilising BIM can help with project planning, clash detection, wastage reduction, and costings. Both the 142 mm and 172 mm Kingspan TEK Cladding panels are available as BIM objects in Revit and IFC formats. Please visit www.kingspaninsulation.co.uk/BIM for more information.

Six Months in the UK’s First Energy-Positive Office

The UK’s first energy positive office, the Active Office, was opened in June last year at Swansea University. Designed by SPECIFIC Innovation and Knowledge Centre to be powered entirely by solar energy, the Active Office aims to generate more energy than it consumes over the course of a year.

The Active Office isn’t just meant to be a high performance building for its own sake, but also to demonstrate how well buildings can perform with technology available today. The building is packed full of cutting edge, commercially available technology to help generate, store and manage energy for the building.

One piece of technology provides both electricity and heat to the building; the photovoltaic thermal (PV-T) system by Naked Energy. Made up of a number of photovoltaic panels contained in vacuum sealed tubes, the system has been mounted onto the front elevation of the building and could potentially provide heat energy for the entire building through spring, summer and autumn.

More solar energy is collected through the roof which is covered in, or more accurately made up of, solar cells. The PV cells are bonded directly onto pre-painted steel to create a roofing system that can be installed using conventional methods. The Active Office features the first commercial installation of BIPVco’s technology on a curved profile, which aside from adding architectural flair, will also generate power throughout the year even in low light conditions.

The various systems are monitored by extensive metering installed throughout the building, enabling SPECIFIC to determine where energy is being generated and consumed. This is reflected in a real time display in the entrance foyer, allowing occupants and visitors to find out how the building is performing.

However, the building can’t reach its energy positive target if all the energy it generates is wasted. “We took a fabric-first approach to reducing energy consumption,” commented Joanna Clark, Building Integration Manager with SPECIFIC and Architect for the Active Office.

The Active Office was designed and conceived by SPECIFIC Innovation and Knowledge Centre and funded by Innovate UK with support from Swansea University and the European Regional Development Fund through the Welsh Government.

It was manufactured offsite by Wernick Buildings, in their factory in nearby Port Talbot. SPECIFIC knew that modular construction could deliver the levels of performance they needed against a challenging programme and budget.

Months later, the choice of modular is being borne out by data. On current performance, SPECIFIC predict an annual consumption of approximately 20MWh versus an annual generation of 24MWh.

The future looks bright for this new type of solar-powered building design. In September, the Chancellor of the Exchequer Philip Hammond annouced funding for the Active Building Centre through the Industrial Strategy Challenge Fund and UKRI. The new independent national centre will seek to remove barriers and accelerate market adoption of new Active Buildings.

It seems likely that modular construction will play an important part in progress towards a low carbon future.

Cementing Compliance…

Over the past 100 years, through-wall construction has probably never seen such a period of significant change as what it has experienced in recent years. Traditional products that have become ingrained in building practices now require adapting because of changes to standards and performance requirements – most notably in relation to fire and thermal. John Taylor, Technical Director at Euroform, discusses the importance of continued product innovation to ensure that popular methods of modern construction – particularly facades in high rise buildings – can still be used.

Following changes to Part L of Building Regulations (England and Wales) surrounding the conservation of fuel and power and Approved Document B in relation to fire safety, there has been a renewed focus on the combustibility and thermal performance of building fabrics. Insurance companies have also tightened their approach and introduced new stipulations which dictate fire strategy. These changes have been welcomed by the industry in the best interest of safety and sustainability, but a new standard has been established for manufacturers and specifiers to comply with.

Building board specialist, Euroform, has responded to these market changes with the launch of A2 Versapanel®… a market-leading cement particle board which has been independently tested in accordance with BS EN 13501-1 and certified as a Euroclass A2 product.

A class of its own

Versapanel® is a widely specified product in building envelope applications and is long established in the market, proven to perform acoustically and deliver exceptional performance in the presence of moisture – cut edges do not require sealing to prevent degradation. In response to market demand for a simplified route to limited combustibility, Euroform has invested in the development of A2 Versapanel® to deliver enhanced fire performance.

The Euroclass A2 certification confirms the high mass and robust exterior lining of the boards is of limited combustibility when exposed to fire conditions.

As compared with standard Versapanel®, the new A2 Versapanel® delivers superior pull out resistance, with comparative tests demonstrating a marked improvement on an already very good performance. Offering superior mechanical performance as compared with exterior gypsum boards, A2 Versapanel® also helps to improve the air tightness of facades when sealed at joints. A wide range of finishes can be applied over A2 Versapanel®, including insulated render systems, terracotta cladding systems, high performance cladding systems and traditional brick coursework.
The launch of A2 Versapanel® is also timely for the construction industry. The simplified route to revised Approved Document B compliance is seeing many developments specify insulation materials which offer limited or non-combustibility – which place additional demands on the performance of the building boards in through-wall build-ups.

In the thick of it

The move to use materials of limited-combustibility in construction, particularly in high-rise buildings has resulted in the specification of heavier and thicker mineral-based external wall insulation. The industry has become accustomed to using light-weight building boards but building boards with a higher mass and robust exterior lining are often required to secure increased volumes of insulation.

A2 Versapanel® is an ideal solution as it offers enhanced mechanical performance and pull out resistance for help attaching insulation. In addition to mechanical strength, A2 Versapanel® also has excellent acoustic properties, which assists developers in constructing buildings which promote occupant comfort by minimising sound transfer from external noise sources.

From a handling perspective, A2 Versapanel® is supplied as standard in 2400mm x 1200mm boards in 10mm and 12mm thicknesses. The product can be cut to size on-site or provided in a pre-fabricated kit to simplify installation processes. CE marked according to BS EN 13986:2004+A1:2015, A2 Versapanel® has been independently tested as A2-s1,d0 reaction to fire according to BS EN 13501-1: 2007+A1:2009.

For further information on A2 Versapanel® or to learn more about specifying the product on buildings above 18m high, please visit www.euroform.co.uk or email info@euroform.co.uk.
