Added Green Roof protection for former WWII bunker

Originally built in 1941 as a special decoy target for German bombers, The Decoy Bunker is tucked away in the rolling hillsides of Monmouthshire and has been fully restored as a unique holiday home.

As the bunker had to blend directly into the hillside, a highly durable waterproofing system was needed to provide full protection against water travelling down from the surrounding landscape: a green roof waterproofing solution that would provide the desired ‘camouflage’ effect by using the existing soil and grass from the surrounding landscape.

Alumasc’s Registered Contractors Span Roofing installed Blackdown Greenroof Drainage Layers, Intensive Substrate and Washed Pebble Ballast to finish the green roof. A Derbigum Black Anti-Root Built-Up System sits below the green roof and provides a highly reliable waterproofing solution and maximum peace of mind for the future, as the Derbigum system holds 40-year durability certification with the BBA (British Board of Agrément).

Rinnai announces price hold for second year

 

Rinnai, the UK leader in hot water heating units and systems for all commercial and residential sites, has announced that it is holding its price for the second year in succession – in the face of reports that some other manufacturers are increasing prices by almost 5%.

Two other manufacturers are reportedly ghosting through price rises of between 3 – 4.5%.

“We see no justification whatsoever to submit price increases and seek to stabilise market prices for our customers. We offer what we believe is a first-class product proposition of energy efficiency, economic cost in use, limitless hot water on demand where you only pay for the fuel you use to heat the water, completely compliant with all existing or pending UK and EU legislation”, says Rinnai Managing Director Tony Gittings.

The Rinnai natural gas or LPG water heaters guarantee a limitless supply of accurately temperature controlled safe and useable hot water. The Rinnai range delivers energy saving performance and low greenhouse emissions through new low NOx burner technology.

All units and systems can be installed as stand-alone or manifolded to provide unlimited hot water for the largest of all commercial sites such as big hotels, busy gyms, high rise offices etc.

Water temperature is and can be pre-set through easy-to-use built in digital controls, eliminating the risk of scalding. The newly updated Rinnai Infinity range is designed for use directly off the mains, with no need for large, ungainly and energy inefficient storage vessels.

Rinnai Heavy Duty water heaters are high efficiency gas continuous flow water heaters with outputs up to 69kW. Incoming water temperatures of up to 60°C are accepted, making the HD50i suitable for secondary return systems. Water can be delivered at high volume with minimum gas consumption. All models have full electronic ignition with no pilot light and operate on demand only, consuming no gas when not in use.

All Rinnai internal HDC condensing continuous flow water heaters, are room-sealed, power flue appliances, while the external weatherproof models have forced exhaust which enables them to be compact, saving both floor and wall space.

Rinnai’s unique condensing technology incorporates two heat exchangers to achieve optimum water heating generated from every cubic metre of Natural Gas or LPG. The condensing process delivers up to 95% thermal efficiency, which translates to significant energy savings when compared to standard on-demand water heaters or conventional stored systems.

Ecobuild keeps finger on the pulse of industry issues with new sustainability showcases for 2018

, ,

A series of exclusive Sustainability Showcases is set to be launched at ecobuild 2018 as new owner, Futurebuild Events Ltd, looks to put sustainability back at the heart of the industry-leading event.

Following its acquisition of ecobuild, Futurebuild Events called on industry to provide feedback, input and support to collaboratively shape ecobuild 2018 and ensure the event remains as relevant and invaluable as possible.

Curated alongside leading architects, manufacturers and designers – and developed as a direct response to industry feedback – the Showcases will form a 1500m2 area at the very centre of ecobuild dedicated to innovative sustainability features.

Building on the conference programme and seminar series, the Showcases will add a further dimension to the event, delivering a range of interactive installations and demonstrations – from full scale builds that could solve the housing crisis to pocket parks that can better build community – that offer direct, tangible solutions to the biggest issues facing the industry.

Martin Hurn, managing director of Futurebuild Events, explains “ecobuild is well-renowned as the must-go event for forward thinkers in the built environment.

This reputation is built on the event’s track-record of collaboratively showcasing and championing the very latest thinking and approaches from across the built environment, and indeed further afield. Under independent ownership, we’re determined to further enhance ecobuild’s commitment to industry innovation and sustainability.

“The Sustainability Showcases represent this commitment in action and are all about bringing the latest thinking from across the industry to attendees in a way that they can physically interactive and engage with. Each Showcase promises to be a thought-provoking and striking event highlight, yet all also offer very practical and achievable solutions to the current issues we face. They will also feed into the main conference programme, which will be shaped around delivering the UN’s Sustainable Development Goals and place sustainability firmly at the heart of everything ecobuild 2018 is about.”

The Sustainability Showcases are:

Zero Bills Home Lite
ZEDfactory returns to ecobuild with a full-scale build designed to tackle the housing crisis. The zero-net carbon home is designed to minimise fossil fuels and annual energy bills, while also reducing build times to four weeks.

Passive Pod Exhibition House

How the life-cycle of a product can reduce its environmental impact

In October 2009, the European Commission (EC) published a framework Directive for energy-related products, thereby extending the scope of application to products that use, generate, transfer and measure energy. This includes products under the previous scope (e.g. electrical appliances) as well as other products such as windows and insulation.

The objective is to reduce greenhouse gas emissions and other adverse environmental impacts throughout the life-cycle of a product. Emphasis is being placed on the design and development stages of a product with a view to improving its energy efficiency.

Ecodesign regulations require manufacturers to decrease the energy consumption of their products by establishing minimum energy efficiency standards. By setting these standards at European level, manufacturers do not have to navigate through multiple national regulations when launching their products on the market.

The ecodesign requirements for individual product groups are created under the EU’s Ecodesign Directive, a process managed by the European Commission.

From a product perspective, there are really two main aspects that manufacturers need to consider, namely seasonal efficiency of the appliance and the emissions, notably of nitrogen oxide. The regulations establish how these factors are calculated but the essence is to increase efficiency of the appliance whilst reducing its emissions of nitrogen oxide.

The energy-related products directive has already been implemented for washing machines, TVs, kettles, gas boilers and a number of other products and the new regulations will be applying to warm air heaters from January 2018.

There are essentially two critical dates that need to be recognised.

  • For all warm air heaters, the requirements for Seasonal Efficiency must be achieved on the 1st of January 2018.
  • For all warm air heaters, the requirements for Emissions (NOx) must be achieved on the 26th of September 2018.
  • For Johnson & Starley air heaters this means that the standard efficiency Hi-Spec and Economaire ranges will not meet the seasonal efficiency requirement at the 1st of January 2018.

To enable the heaters to be placed on the market they must be fully compliant with the regulation.

However, appliances in the supply chain after the implementation date, can still be sold but they must be covered by an order, written or verbal. In other words, orders would need placing for the non-condensing ranges of warm air heaters, the HiSpec and Economaire, by the end of December 2017 to comply with the new regulation. Providing these orders are in place, Johnson & Starley are able to sell these two models of heaters up until 26th September 2018

Naturally, Housing Associations and Social Housing who currently own, or are looking to upgrade their stock will wonder what the availability of spare parts will be. There is need to worry.

Johnson and Starley has always been committed to keeping spare parts for heaters available for as long as possible and will not be making exceptions for these or any of our model ranges. Parts will be available for a minimum of 10 years after production of these 2 models of heaters has ceased. Johnson & Starley currently supply spares for heaters that are 50 years old as we believe cost of ownership is extremely important to our customers.

We are so confident in our products that we are extending the guarantee period for the Economaire and Hi-Spec heaters from 1 to 3 years

So what will be the Johnson & Starley warm air heater line-up be from 2018 onwards? We launched our highly successful range of WarmCair condensing heaters in 2013 which now come with a 5 year Guarantee. Our market leading QuanTec range of boilers can connect to the Aquair our warm air heat emitter range. Again these come with extended Guarantees of 8 years for the QuanTec range of boilers and 5 years for our Aquair range.

These units are highly efficient, giving customers significant savings on running costs and meeting all future ecodesign regulation requirements, future proofing our market leading products and giving warm air a strong footing for the coming years as Hi spec and Economaire hand over the baton.

Westgate Oxford revitalized with Kingspan Kooltherm

The premium thermal performance of Kingspan Kooltherm K106 Cavity Board has led to it being installed as part of the £440 million redevelopment of Westgate Oxford, a retail and leisure destination in the city centre.

Developed by the Westgate Oxford Alliance and constructed by Laing O’Rourke, the development is scheduled to open in October 2017. It has been designed by Glenn Howells Architects to reflect the heritage of the surrounding Oxford architecture, with an articulated brick façade and a focus on long-term robustness, quality and endurance. This concept was carried throughout the project, leading to the selection of the Kingspan Kooltherm K106 Cavity Board to ensure the building achieved a high level of thermal performance within a minimal cavity width.

Installed by Kilnbridge Construction Limited on the stair cores at each level, the rigid insulation board has a thermal conductivity of just 0.018 W/m·K, whilst its water-tight, vapour-open polypropylene fleece outer facing allows it to be installed with a 10 mm residual cavity. This combination makes it ideal for projects such as Westgate Oxford, where developers want to meet demanding U-value targets, without moving away from preferred cavity sizes and reducing the internal space.

The Oxford development is expected to achieve a minimum BREEAM rating of ‘Excellent’ for Block 1. Kingspan Kooltherm K106 Cavity Board can assist, both directly and indirectly, towards the award of credits within the Energy and Materials sections of the assessment. All Kooltherm, Therma and KoolDuct insulation products and cavity closers manufactured at Kingspan Insulation’s facilities in Pembridge and Selby are certified to BES 6001 (Framework Standard for the Responsible Sourcing of Construction Products) ‘Excellent’.

Kingspan Kooltherm K106 Cavity Board is BBA certified. Its rigid phenolic fibre-free insulation core is manufactured with a blowing agent that has zero Ozone Depletion Potential (ODP) and very low Global Warming Potential (GWP). The insulation boards are non-deleterious, easy to handle and install, and are unaffected by air infiltration.

Zero Waste Goal and CO2 Savings for SFS intec in Latest Sustainability Boost

Leading fastener manufacturer, SFS intec, has strengthened its position as one of the sustainability innovators in the roofing and cladding sector by implementing two new initiatives that significantly reduce the environmental impact of its Leeds HQ and production site.

The company, which is one of the world’s largest producers of fastening systems for the built environment, has just made a major investment to reduce energy consumption within its premises located close to Leeds city centre. Working in conjunction with its OEM customer Kingspan, SFS intec has installed a new ultra-low energy LED lighting system that will save 65 tonnes of CO2 per annum, in addition to providing a much brighter and more comfortable working environment for SFS personnel.

By removing the 349 original light fittings and replacing them with 155 low-energy LED lights, SFS intec is cutting its annual electricity consumption for lighting by nearly three quarters. The new LED lights allow for customised lighting levels which adapt to the amount of natural light entering the building through rooflights and windows.

In a separate programme to reduce its carbon footprint, SFS intec has also appointed a new partner to help it maximise recycling and eliminate landfill waste. Working with waste management specialist ACM Environmental PLC, new processes implemented right across the site will ensure all the company’s cardboard, dry mixed recyclables, wood, scrap metal and general waste is separated and sent to recycling plants, with none sent to landfill.

Luke Wood, QES Manager at SFS intec, who led both sustainability programmes, said “We’re always looking at utilising new technology, services and processes to ensure we’re operating in a sustainable way, guided by the three ‘P’s of sustainability – People, Planet and Profit.

“Cutting our energy consumption and waste help us to minimise our carbon footprint and maintain our position as an environmentally sustainable supply chain partner for all our built environment customers. Our next programme is looking at our consumption of gas for heating and to power our air-handling systems and, when implemented, could deliver even further CO2 savings.

“The fastening systems we manufacture and supply are often used in low and zero carbon buildings, so it is important for our customers to have confidence that each SFS intec product used is manufactured sustainably. That’s where we add value and give the industry a ‘greener’ choice.”

SFS intec manufactures a wide range of fastening systems for all types of roofing and cladding applications. The company is part of the Swiss-based SFS Group which has annual sales in excess of £1.1bn and a history dating back to the 1950s serving customers in the construction, automotive, electronics, industrial and medical products markets.

Leading Eco-Roof company calls for Yorkshire colleges to upskill or risk being left behind

,

Huddersfield-based energy efficiency roofing specialist, Ploughcroft, has issued a stark warning to construction colleges across the region: upskill and evolve, or risk being left behind in the fast-moving roofing industry.

With hundreds of students leaving construction colleges to seek employment this summer, Chris Hopkins, Divisional Director at Ploughcroft, is warning the majority of those leavers will be untrained and unprepared for the energy saving construction techniques that consumers now demand.

An industry first

As a consequence, Ploughcroft has taken the initiative to develop its own pioneering, Eco-Roof apprenticeship scheme – which has already been trailed over the last 12-months. This is believed to be an industry first.

This proactive approach from Ploughcroft is essential to provide apprentices with the skills and knowledge required to succeed in the fast-growing energy efficiency industry, and to underpin the cost-effective installation of new roofing schemes.

While under the current college curriculum, the focus quite rightly covers the basic roofing installation essentials, it fails in the view of Chris Hopkins, when it comes to the incorporation of now crucial energy efficient-related skill sets, such as U-Value calculations, condensation risk analysis and heat-loss monthly savings.

This means forward-thinking companies such as Ploughcroft, which lead the way with its unique Eco-Roof product, are unable to find suitably qualified staff, even at entry-level positions, further exacerbating the industry-wide skills shortage. Ploughcroft believes that by ‘future proofing’ the Apprenticeship schemes, this will also have the knock-on effect of attracting the brightest and best to the industry.

Chris Hopkins is now calling for urgent dialogue with course and curriculum planners to collaborate to address this key area. He said “Over the past three years we have seen a rapid growth in our Eco-Roof business, as energy prices continue to rise, and customers become increasingly clued-up when it comes to greener living and the impact it can have on their energy bills.

“However, while consumer demand rises, colleges simply aren’t keeping up. Given there was no existing eco roof apprenticeship scheme in place that covered the type of specialist work we carry out, we’ve been trialing and created our own using my professional teaching and roofing assessor qualifications.

“That said, we can only do so much, and today’s apprentices are the people who will drive the energy efficiency industry forward in years to come. As such it is absolutely essential that colleges – and other construction businesses – continue to evolve, and invest in skills and development.”

One of Ploughcroft’s most successful apprentices is 18-year-old Charlie Oakes, who began his apprenticeship in 2015 when the scheme launched. He says: “Joining the Eco-Roof apprenticeship has been a fantastic experience. Roofing is often seen as industry that lacks innovation, but working at Ploughcroft I’ve found that’s not the case, and I’ve learned a great deal about emerging energy efficiency techniques. This is a huge growth area, and one I’m excited to see developing.”

Ploughcroft’s two-year Eco-Roof apprenticeship offers a mix of on-the-job training and classroom-based learning spanning traditional roofing, as well as a wide range of cutting-edge, energy-efficient construction techniques required to meet the needs of this fast-growing eco-construction sector. It is currently seeking graduates to join its Eco-Roof apprenticeship scheme.

Brio puts a curve in it

Brio architectural hardware made an adventurous curved door project a reality for an innovative wedding venue in north Devon.

Tunnels Beaches is a network of hand carved tunnels leading to sheltered beaches and a tidal Victorian bathing pool at Ilfracombe, the location of a breath-taking beach front wedding venue operated by Devon Beach Weddings. The bespoke building curving out of the rock means there are no concerns about the UK weather and whatever turn it takes it is all visible through curved bi-folding glazed doors – whether opened or closed.

The owner had the idea to refurbish and at the same time to extend the upper story of the curved building by 2 metres, installing curved bi-folding glazed doors and thereby increasing capacity from 130 guests to 160. With a full house for weddings in 2017, (120+ weddings booked), over 100 weddings already booked for 2018 and prime dates in 2019 booking fast, the extension was a must.

Awlwood Joinery already had a good relationship with the owners Jamie and Zoe McLintock having worked with them at the Tunnels Beaches Bath House – an old Victorian bath house – which was turned in to wedding accommodation for the venues guests, so when the scheme was mooted to install curving bi-folding doors the McLintock’s turned to David Wray at Awlwood Joinery. “It wasn’t anything we had done before but we are skilled guys and the concept is not beyond the reach of man – after all we can send men to the moon – so we undertook the commission. The architect, RGP of Barnstaple, came up with a scheme and we did as they instructed – but with fewer doors (two sets, opening out). The design included wood cladding and lots of steel.

“We opted for the Brio Weatherfold 4s system after talking to Bob Harrison at Hebden & Holding architectural ironmonger and the Brio team which takes panels up to 1 metre wide. The decision was led by the architect’ plans and the constraints of the timber as you cannot have huge pieces of curved timber so we had to make up the doors from smaller pieces that would eventually be bolted together on site. The actual frame was put together by the owner’s site carpenters.”

David Wray says: “I am very pleased with the results especially with Brio’s new dual point locking mechanism. Most bi-folding doors are locked top and bottom which means reaching up and bending down to operate. The new Brio system is a finger locking mechanism. I am so impressed with it I am using it on all jobs. It may be more expensive but it is well worth the investment for the huge improvement and simplified operation and it looks so much better.

Brio’s 286 Dual Point Lock system launched last year has been joined by Brio’s 288 Lever Furniture to give joiners a deluxe option to offer their customers who now, more than ever, are looking for aesthetics as well as practicality.

Brio’s 286 Dual Point Lock is suitable for Brio’s tough exterior folding system Weatherfold 4s with timber or aluminium panels and for single hinge panels, such as French doors, up to 3.5 metres high, offering an alternative to the standard flushbolts. It is both ultra secure and aesthetically pleasing.

Rather than having the standard flushbolt at the top and the bottom of the door system on the inside of the property the end user can now choose a more sophisticated finish with the 288 lever handle readily accessible in the central part of the door so there is no reaching up or bending down to operate bolts.

“I am also impressed with Brio R&D – they are always coming up with new ideas and fixes. Best on the market. The solutions are effective and the Brio representatives are helpful and thoughtful – that’s a one-off!”

According to David Newton, General Manager UK at Brio, the demand for bi-folding and sliding exterior and interior doors is set to continue apace, with a variety of aesthetic demands from delicate ‘floating’ glass systems to commercial style projects such as this example in North Devon. “What this means in practice is that Brio, with its range of product and flexible attitude, will continue to keep pace with the architect’s need for innovative product that can transform anything they design on paper into reality,” he says.
