Recycling company of the year

FM Conway has been named as Recycling Company of the Year in the Construction Recycling Alliance (CRA) awards 2011.

The company was selected by a panel of judges, comprising academics, journalists and government policy makers who said that FM Conway’s work was deemed ‘commendable throughout’.

Michael Conway, CEO of FM Conway, said: “Being named as recycling company of the year is a fantastic achievement for the company and makes everything we do worthwhile.

“We try to demonstrate a commitment and embedded approach to improving our sustainability within the organisation and promoting an environmentally aware ethos across the company.”

FM Conway has invested £25 million on in-house recycling infrastructure over the past five years and now has the ability to recycle a wide array of materials in-house including; 100% of highways arisings into new aggregates and 100% of asphalt into new 95% recycled content asphalt.

With the only gully waste recycling plant in the UK, 95% of gully waste is recycled as well as all kerbs, paving, concrete, asphalt, sub- base, sand and granular materials.

In 2010, FM Conway saw more than 250,000 tonnes of waste diverted from landfill, 220,000 tonnes of recycled products supplied to sites and more than 220,000 tonnes of virgin aggregates saved.

The company’s new asphalt plant, which opened in 2010, incorporates the latest automated technology and is the UK’s only asphalt recycling solution and recognised as one of Europe’s most innovative construction recycling plants.

FM Conway has developed a 95% recycled binder and surface course which exceeds the 40% recycled content of the material used by its competitors, at a similar cost. This recycled product has already been successfully used in resurfacing contracts for its clients in London Boroughs.

Figures also show in 2009/201 that 5,000 tonnes of CO2 emissions were saved and it is estimated that in 2011/2012, there will be a further reduction of 7% in energy use and a commensurate reduction in CO2 emissions, saving more than 8,250 tonnes per year.

More than seven million litres of water were recycled in 2010, reducing the company’s water needs. The newly constructed Thames-side jetty, which will open later this year, will enable materials to be delivered and dispatched by river, saving more than 15,000 lorry movements per year.

Michael Conway added: “We are working hard to develop and deliver innovative products that meet our client’s growing needs for green solutions, and being recognised for our hard work shows we are in the right direction.”


Sustainable drainage guide

A detailed and informative Guide to Sustainable Drainage Systems (SuDS) in the Urban Landscape has been published as part of the Engineering Nature’s Way initiative by Hydro International.

The guide can be downloaded for free by visiting www.engineringnaturesway.co.uk, the web-based knowledge resource for SuDS and flooding in the UK. It is jointly authored by Prof Richard Ashley of EcoFutures, Sue Illman of Illman Young Landscape architects and Alex Stephenson, Stormwater director of Hydro International and chair of the British Water SuDS focus group.

The Guide considers the issues surrounding the development of SuDS techniques in urban settings. Topics considered include SuDS and ecosystems services, green infrastructure, water sensitive urban design and retrofitting SuDS, including in highways applications. The Guide also provides practical advice on component selection from the full SuDS toolbox.

“Sustainable surface water management measures can help create a more balanced and natural ecology in our towns and cities. For too long, we have paved over green spaces and treated the resulting surface water runoff as a problem or waste,” said author Alex Stephenson.

“A creative approach to planning for water above ground – in which stormwater is seen as a resource providing multiple benefits – can help make the urban landscape a more balanced, healthy and enjoyable place to live.

“The Guide demonstrates that a correct interpretation of SuDS is one that can be applied to every development. It’s simply no longer acceptable to have an ‘either or’ choice between SuDS or ‘not possible’. A range of techniques, natural, manufactured or combined are available to recreate (or improve on) natural drainage paths.”

Halving landfill waste

Staffordshire manufacturer, Instarmac Group, has recorded a 51% reduction in its waste to landfill.

Instarmac, incorporating Ultracrete, Ultrascape, Ultra Tile and Ultra Floorbrands, has more than halved its waste to landfill as part of its dedication to reducing its environmental impact.

The company has a list of environmental programmes that have included transparent waste stream development, investment in solar and wind powered energy, and providing shredded paper for use at local Twycross Zoo to keep the animals warm in winter.

Instarmac has received recognition for its environmental and sustainability schemes, as well as its projects to boost lean efficiency. The most recent accolade comes from UK’s FeRFA (Resin Flooring Association) where it was shortlisted for an ‘Environmental Initiative’ award. For two years running the company won the same award presented by The Tile Association, for its waste stream processes, recycling and green ethics.

Darren Gough, QHSE manager said: “I am delighted we have reduced our landfill waste by such a huge percentage in a short space of time. We are now looking towards achieving zero waste to landfill.”

Passiv Haus range

Internorm claims to be the only window manufacturer in Europe with nine Passive House certified components.

Thomas Hagen from Internorm said: “The window in a Passive House plays a key role. It can reduce heat loss while optimising thermal gain. In order to achieve this, there are a number of essential principals that need to be met. Firstly, the system requires highly insulating glazing, with a U-value less that 0.80 W/m2K, and should have a g-value of 50% or more.”

The newest addition to Internorm’s Passive House certified range, Thermo Passiv, is a PVCU or PVCU/aluminium window system, which is available with an aluminium attachment cover on request. The system is fitted with new triple glazing as standard and achieves heat insulation values up to 0.69 W/m2K. The product’s sash in ‘Vetro’ design allows frameless, modern glass architecture and narrow view widths up to 87mm.

Internorm also offers Dimension 4 and Passion 4, which are composite PVCU/aluminium clad window options. This system offers integral blinds for privacy and sun protection and is available in both Premium and Softline design.

For a timber/aluminium Passive House certified window, Internorm offers many designs – Premium, Softline and Classic. For a timber/aluminium composite window, there are three options – Varion 4 in flush design, the Varion 4 in Vetro design and Edition 4, which is available in Premium and Softline design. All three windows have integral blinds for privacy and sun protection. The windows feature excellent energy performance and outstanding sound reduction of 45db (with standard glazing).

The PVCU/aluminium clad and the timber/aluminium-clad can be used in the same project as both systems use the same aluminium cladding on the outside. Visually there is no difference – even if one is a PVCU window.

For Passive House entrance door specification Internorm offers its Selection and Selection 2. Both are timber/aluminium house entrance doors with the capacity to deliver a thermal insulation value of 0.79W/m2K. Each comes in a wide selection of designs to suit different architectural styles. There is also a range of balcony and side entrance doors available.

Aiming for net-zero energy

Kingspan Insulated Panels’ head office in Kingscourt, Ireland has installed the Kingspan Roof PowerPanel System.

1000m2 of photovoltaic modules were installed by Northeast Electrical to more than offset the total annual electricity usage of the Group offices in what is thought to be one of the largest PV installations in Ireland. The 130kWp system, which comprises of five hundred and fifty three 235Wp Yingli crystalline PV modules, is expected to generate circa 100,000 kWh per annum.

Similar systems have already been installed at Kingspan Insulation’s manufacturing facility in Pembridge and Kingspan Insulated Panels’ plant in Holywell. At 800kW and 406kW respectively they are currently two of the largest roof-top PV arrays in the UK, the company claimed. At both plants the PV systems were designed to supply a significant proportion of the site’s lighting and manufacturing electricity needs.

Gilbert McCarthy, managing director of Kingspan Insulated Panels, said: “There are so many ways we can take action towards achieving net-zero energy, and it is important to lead by example. We are planning to roll out a basket of measures across all of our operations, and are already working on the next phase to move our own manufacturing sites towards net-zero energy. It is a real challenge for manufacturers, but one that is well worth pursuing, both in terms of cutting energy costs, reducing our reliance on power from the grid and exceeding customer expectations in managing our own environmental impacts.”

Commissioned and approved by ESB on the 10th October, the Kingscourt system took just two weeks to complete, and is predicted to save around 52,500Kg/CO2 per annum. The installation will make a significant contribution to reducing carbon as well as generating energy.

The addition of a Kingspan Safetraxx off-ridge fall arrest system, which was designed and installed by Skyway, means that the ongoing maintenance of the Kingscourt PV system has been made both safer and easier. Safetraxx complies with BS EN 795 and, when installed in conjunction with Kingspan insulated panels, is available with the Kingspan 25 year Total System Guarantee.


‘Eco’ infill panels

Panel Systems has released an environmentally friendly window infill panel – the Aluglaze eco.

This new addition to the company’s range of architectural panels comprises a tough, double skinned polyester-coated aluminium bonded to a core of Styrofoam LBA insulation.

Aluglaze eco is predominantly specified where aesthetics and sustainability are required.

Danny Phelan, sales manager for Panel Systems, said: “Aluglaze is widely used for many projects and we expect this latest addition to the range will enhance its popularity even further. Specifying Aluglaze eco infill panels can help building designers to achieve the highest performance and sustainability requirements on BREEAM projects.”

The insulating properties of Aluglaze eco are provided by its Styrofoam LBA core, designed for projects that require high standards of environmental performance. This is because the material uses carbon dioxide as the blowing agent, which has an Ozone Depletion Potential (ODP) of zero and Global Warming Potential (GWP) of less than five, therefore meeting the requirements of BREEAM.

Concern about ozone depletion in the stratosphere has led to international agreements to phase out the use of such depleting chemicals, making Styrofoam LBA a popular choice.

The new Aluglaze eco panels can achieve very low U-values, down to 0.15 w/m2K with an increased thickness of Styrofoam LBA over the standard 28mm panel, which achieves a minimum U-value of 1.12w/m2K.

Aluglaze eco is available in the full range of Interpon D and Syntha Pulvin powder coating colours, for use in architectural applications, where aesthetics and long term low maintenance are all important

All Aluglaze eco panels are supplied cut to size to the contractors’/specifiers’ own dimensions. Customer sizes are optimised using the latest ‘Magicut’ software to minimise the amount of material wasted. All panels are vacuum-pressed with a two part polyurethane adhesive.

Panel Systems is a holder of Bureau Veritas certification and manufactures all products to standard BS EN ISO 9001:2008.

‘A’ for efficiency

Altecnic’s fully accredited Ecocal thermostatic radiator valve has achieved the European ‘A’ efficiency rating.

Altecnic’s patented Ecocal has been tested against the stringent requirements of the European Valve Manufacturers’ Association, ‘Thermostatic Efficiency Label’ (TELL).

The rigorous process classifies the energy rating of individual valves by examining the extent to which the user can detect immediate cost-savings and how easy the device is to fit and operate, all valves must also be BS EN 215 certified.

Engineered for both retro-fit and new installations, Ecocal is available in 8mm, 10mm and 15mm and is designed with a serrated sliding tail piece allowing easy installation by helping to prevent alterations to pipework and ensuring PTFE sealant bonds securely.

The straight or angled device has a fully reversible body for either vertical or horizontal fit that is suitable for on flow or return pipework, providing installers with ultimate flexibility.

The Ecocal is available in a white and chrome finish with matching lockshields and are liquid filled to instantly react to changes in ambient temperature. A positive off position also allows the radiator to be removed without the need to be drained.


Green award

Homeline Building Products has been awarded ISO14001 for its green credentials and environmental responsibility.

The company also attained recognition as the UK’s first roofline manufacturer to launch a BBA accredited recycled roofline system.

The ‘Core’ range of fascias and soffits are virtually indistinguishable from Homeline’s standard range but are manufactured with an inner core of recycled PVC-U encapsulated within a virgin shell to produce the perfect finish.

Julian Allen, Homeline’s group manufacturing manager said: “It has always been our firm intention to drive forward with our goal of producing a range of environmentally friendly PVCU building products to distribute across the UK, meeting the demands of both retail and commercial customers.

“Achieving ISO 14001 – in addition to a further investment in our mixing plant to produce our recycled roofline – demonstrates our commitment to environmentally responsible manufacturing.

“This achievement is testament to all the hard work and dedication shown by our team at Homeline Building Products, and emphasises the company’s commitment towards continuous improvement in everything it does”.

Future proof?

A premium range of windows and doors that is future-proof to 2019 has been launched in the UK by Kawneer.

The AA720 series comprises a tilturn, inward-opening side-hung and bottom-hung, tilt slide, vertical and horizontal pivot, top-hung casement, inward and outward-opening doors, folding/sliding door and a fire-rated door and fixed light.

The range, with U-values as low as 0.9 W/m²K, is expected to outperform the anticipated requirements of the 2013 and 2016 Part L amendments to Building Regulations.

The windows are available in four levels of thermal performance – the AA720, AA720 HW, AA720 HI and AA720 HIPlus. The series of wider 72mm profiles incorporates the very latest thermal technology including extruded polyamide and ABS thermal breaks, insulated centre seals, foam isolators and foam core insulation.

The doors are available in two levels of thermal performance – the AA720 and the AA720 HI. Here, the series of wider 72mm profiles incorporates extruded polyamide thermal breaks and foam core insulation.

Expected to supersede the AA600TE series as Kawneer’s flagship range, the AA720 series is based on a range that has performed in Germany, an even more onerous market, regulations-wise, for several years, becoming Kawneer’s best-seller there. Its launch in the UK has required the largest-ever investment in new dies at Kawneer’s factory in Runcorn, Cheshire.

The windows encompass a wide variety of configurations – the standard window with traditional straight contours, and five new variants – the softline with rounded contours particularly suitable for residential applications, the integral (concealed vent) with narrow sightlines and visible aluminium facets on the vents, the renovation with angular or chamfered contours, a narrow sightline window for the replacement of steel heritage windows, and a curtain wall lookalike.

The doors comprise a standard door with straight contours that is available in open-in and open-out variants, a design door with rounded and angular contours to suite with the softline window for residential applications, and the AA720 FR fire-rated system for doors and fixed screens which has been tested to 30 minutes for integrity and insulation.

All the windows and doors offer extensive hardware configurations including new concealed hinges and barrel hinges for entrance doors as well as a wide variety of handle and locking options.

Move over Movember

Movember is a time when men grow moustaches to raise money for men’s health charities. However, this year, Knauf Drywall’s Beardtober beat it to the charitable finish by a hair’s breadth.

The company renamed the tenth month ‘Beardtober’ and sought to bristle with facial hair from the first and until the beginning of that boring old Movember in order to raise money for Prostrate Project. And that objective was met in whiskery style, with the company raising over £7,000 for the charity.

“The idea was that anyone in the business who can grow facial hair should do so and donate £25 to The Prostate Project for the privilege, while raising sponsorship from friends and family, as well as ‘non-growing’ colleagues, customers and suppliers,” explained Ian Dean, sales and marketing director.

To best judge who produced the best beard in Beardtober, all Knauf Drywall participants participated in a controlled ‘shave off’ on September 30th – with David Riddell, national account controller, receiving an award for sprouting the most prolific set. There was also an award for the worst beard and this was given to Dan Dixon, flooring business development manager.

Ian continues: “We were in a pretty dishevelled state during Beardtober and it sure was an itchy month, but it was all for a very good cause.”

Bright idea

Mitsubishi Electric is using the roof of its three-storey headquarters in Hatfield to significantly lower its carbon footprint by generating electricity and earn income from the Government’s Feed In Tarriff (FIT) scheme.

The company has installed a photovoltaic (PV) system with a net install capacity of 49.4kW using the latest hi-efficiency, monocrystalline PV modules – the MLT255HC – and these are now expected to deliver over 42,000 kWh per year with a CO2 saving of over 22 metric tons.

The two roof sections of the L-shaped building are typical flat roofs with a waterproof membrane covering and in order to avoid penetrating this membrane, Mitsubishi Electric has used a ballasted A-frame system designed and supplied by Big Foot Systems.

The installation was completed by Mitie Energy, the strategic outsourcing and energy services company and the modules are pitched at 10° and orientated at 30° east of due south – a configuration which maximised the use of the available roof space. A Fronius CL48 three-phase central inverter, which has a nominal ouput of 48kW, links the PV array to the building.

As a major player in the PV industry, we thought we should take advantage of the huge flat roof we have here at our Hatfield headquarters to highlight how simple these systems are to install and just how much carbon can be saved and how much electricity generated,” explained Perry Jackson, general manager of the company’s photovoltaics division.

The company is monitoring the performance of the PV system using a Fronius Datalogger web monitoring system. This displays real-time and historical data on a web page that can also be accessed by Mitsubishi Electric’s customers.

New call centre

Quotatis has opened a new UK based call centre to cope with the growing volume of leads and subscribers the company now handles.

At present 15 staff work seven days a week to qualify the leads received from homeowners seeking the services of the qualified trades people registered with Quotatis, a number that will be increased in the New Year.

Every enquirer is contacted and asked key questions about their enquiry, after which the leads are passed on to subscribers.

The opening of the call centre, which is based at the Quotatis offices in Norwich, follows an increase of more than 40% in the number of leads received by the company. There has also been significant growth in Quotatis’s subscriber base as more tradespeople and contractors are experimenting with online lead generation, finding that the costs and quality improve upon their alternative methods.

Quotatis offers a 'pay-as-you-go' system of providing business leads with no join up fee or contract. This offers subscribers control, with businesses paying for as many leads in their area as they require and without any commitment.

Quotatis has also promoted Janet Small to the post of national sales manager with a replacement team leader being recruited to head the customer service and sales team. Scott Wilson will be responsible for 12 staff in this area.

“We are delighted with the volume of sales leads we are receiving from homeowners,” Quotatis’s sales director Teresa Gizzi said. “Business is really booming in a number of home improvement sectors, especially for photovoltaic panels and boiler replacement and the new call centre is essential to qualify and pass on the leads whilst they are still current and effective.”


Efficiency award

Rehau won the Energy Efficiency Initiative of the Year award for its Rehau Geneo Passivhaus certified window system and 0.8 triple glazed window with Rehau Thermo insert at the recent G11 awards.

Wolfgang Gorner, business unit director at the Rehau Window Division, said: “Rehau Geneo is a really exciting innovation – not just a new profile design but also a new composite material which showcases the very best of Rehau’s product design expertise.

“Over the past year, we’ve successfully introduced Rehau Geneo into the UK, established a network of fabricators in England, Scotland and Wales and completed a number of high profile contracts in both domestic and commercial projects.

“It demonstrates perfectly the benefits to our customers in the UK of Rehau’s strategy of applying successful product platforms across several markets and of using our experience in one market to inform our development in others.

“Alongside our new 0.8 window and other initiatives such as our online U-Value and WER calculator, it confirms Rehau’s commitment to ongoing innovation in the energy efficiency sector. I was delighted that Rehau come out on top in what was a very competitive category.”

Green credentials

Synseal was nominated and shortlisted for the Green Manufacturer of the Year Award at the ‘Insider Made in the Midlands Awards’, a scheme that rewards the work of the region’s manufacturers.

The Awards Presentation Dinner was held at the Ricoh Arena in Coventry on Tuesday November 2nd.

“Synseal are delighted to have been nominated alongside such a respected group of manufacturers that included Jaguar Land Rover, Morgan Motor Company, AGA Rangemaster Group, Wade Ceramics and SI Group to name a few,” production director Robin Byron said, who attended the event with HS&E manager Glenn Evans.

Synseal was shortlisted on the night, but narrowly beaten by Alumet Group for the Green Manufacturer award. CEO David Leng said: “We are very proud of our carbon reducing ethos which, via our processes and products, stretches to all corners of the UK and beyond.”

Synseal impressed the judges with its environmental strategies that include: a year-on-year reduction in energy consumption of 8%, producing an average saving of 600 tonnes of carbon; a 30% reduction in vehicle emissions through the introduction of 34 new delivery vehicles; and the on-target achievement of zero waste to landfill by the end of the current year.


Solar calculator launched

The recent headline grabbing changes to the Feed In Tariff has left the consumer in the dark, and it is now more critical than ever to restore consumer confidence and provide an accurate calculation of the financial benefits of installing Solar PV, Ecovision has claimed.

Ecovision has developed a Solar Calculator, which should put to a rest any ‘false’ calculations that some companies have been claiming. “Inflated savings and inaccurate installation costs have left many disappointed,” the company said. “Ecovision provides the only service on the internet which quickly and simply works out how much a roof can earn and at what cost.

“The Solar Calculator enables the consumer to click on a Google map image of the house, mark the size of the roof, select the pitch, fill out details and the results are then submitted to applicant’s inbox.”

A quote for two systems will be generated:
• The largest possible solar panel system that can fit, what it will cost and the income it will generate.
• The most efficient solar panel system that can fit on the roof, what it will cost and the income it will generate.
• The quote will include the installation cost, annual tax free payment to you and totals that figure over 25 years at an index linked inflation rate of 3%. The income is made up of the annual FIT, the annual export benefit and the annual savings benefit.

Ecovisions have reacted to the Government’s revised Feed In Tariff with a measure to ensure that consumers committed to reducing carbon emissions and electricity bills can still get maximum benefit from the FIT. With a significant £5,000 reduction in the installation costs to £9,495, the payback is 10 years with 15 years of tax free profit.

“I wanted to create an online tool that could calculate the cost and return from solar panels, of the total or part portion of an individual’s roof space offering the most beneficial solution not just the largest,” Jeff Ryder Ecovision project manager said.

“No-one else did this. It took the full weight of the company's extensive expertise to achieve, from creation of the customer journey to fine tuning the extremely complex formula involved! I encourage anyone considering going green to use the Solar Calculator, it's free to use and backed by the friendly expertise of Ecovision.”


Four panes

Fakro’s FTT pivot roof windows offer exceptional heat transmission co-efficients, having been designed to meet the requirements of energy-efficient buildings such as those built to Passivhaus standards.

Glazing units are set in specially designed wider sash frames which minimize the potential for thermal bridging. With a 50mm thick glazing unit, the FTT U8 Thermo quadruple-glazed roof window has a U-value of 0.68W/m2K, while that of the triple-glazed FTT U6 is 0.81W/m2k. Both have a glass U-value of 0.3W/m2K.

Though of pivot design, the axis of rotation of some FTT sashes has been raised to enable even a tall person to stand comfortably by an open roof window. FTT windows benefit from a quadruple-sealing system using flexible thermoplastic elastomer (TPE) which limits air leakage. As a result, when closed both the U6 and U8 provide a 38 dB acoustic performance.

FTT roof windows can be installed in pitches between 15º and 70º and the sash can be positioned at any point between 0° and 45°. Unlike the relatively open-grain whitewood pine used by some manufacturers, the timber used to manufacture the FTT is exclusively slow growing, close-grain, redwood pine which is guaranteed to be knot-free.

With the additional benefits of vacuum pressure treatment and use of a three-coat matt lacquer finish the timber keeps its appearance for years. Through use of a modified locking mechanism which secures the sash either side of the frame, the patented topSafe system provides an exceptional standard of security and safety – Class 4 EN13049.


Awards trio

Litchfield Group’s Sheerframe, Masterdor and ICF Tech products were successful in the 2011 Housebuilder of the Year Awards.

The trio of low-carbon building products form the structural envelope of homes at Brookwood Farm – the Code level 5 social and private housing development in Woking. The scheme, by the William Lacey Group for Woking Borough Homes, won best low or zero carbon initiative at the Housebuilder of the Year Award which were presented by comedian Alexander Armstrong earlier this month at the Millennium Mayfair Hotel in London.

In total there are 12 homes at Brookwood Farm, of which ten are ‘affordable’.

The combination of ICF Tech walls, Sheerframe zero carbon HED windows and high performance Masterdor entrance doors, all designed and produced by the Derbyshire-based Litchfield Group of Companies, provides the structural framework on which the new homes’ code level performance is based.

Litchfield Group managing director James Litchfield said: “There’s still plenty of talk in the industry about the best ways to meet zero carbon specifications. Our system is already helping to deliver new homes to this standard.

“The fundamental principle to successful delivery is getting the envelope fabric right, and that means well thermally insulated walls, windows and doors which allows for the application of green technologies to enhance the building’s performance.”

The three-step building system from The Litchfield Group, which brings together the proven technologies of thermally superior ICF Tech walls, Sheerframe windows and Masterdor doors for the building envelope, is easy to construct, even in challenging weather conditions.

Walls can be clad or faced to look exactly like a standard red brick and block construction from the outside but they’re dual skinned with ICF Tech’s insulated concrete form walls, which offer U-values as low as 0.11W/m2K, air infiltration performance which meets Code level 6 standards, and a Y value as low as 0.013.

Sheerframe PVC windows with a low 0.8 W/m2K U-value and Masterdor door sets – which are all UK-designed and manufactured specifically for British homes – integrate with the walls to maximise thermal efficiency, air tightness and security.


Multi-occupancy efficiency

Sirius SAT from Potterton Commercial is a range of Heat Interface Units (HIU) for the provision and control of heating and hot water within each dwelling of a residential block of flats that is served by a centralised plant room.

Suitable for use in local authority building stock, a centralised system removes the necessity for individual boilers within each dwelling, allowing quick and easy access for maintenance. This method of heating also results in reduced installation costs, no flues or visible plumage and reduced annual appliance service charges.

Furthermore, it is easier to integrate Low/ Zero Carbon (LZC) energy solutions, like the Andrews Solarflo solar thermal system, the benefits of which can be distributed to all the residents.

The Sirius SAT HIU range includes eight models, depending on the size of the residential block and whether domestic hot water is required in addition to heating. No matter what size they are, the units are all compact and can be installed where space is limited, ensuring ease of installation.

For dwellings with larger hot water loads, HIU models are also available for integration with hot water cylinders.

One of the technologically advanced benefits of this product is its heat consumption meters that have the option of being able to transmit data by wireless, allowing the local metering of heating and hot water consumption in each dwelling to take place from one single position. This reduces meter reading costs and avoids possible reading mistakes. The direct consumption reading is also shown via the clear, digital display on the HIU, which helps to encourage efficient use of heating and hot water by individual residents.

Sirius SAT comes with a range of optional extras, including a programmable room thermostat, aerial/receiver, radio modules, weather compensation module and DHW/ cold water meter and pipework loop.


WiFi enabled

Heatmiser UK has launched its new WiFi Enabled Thermostats that can be controlled via any web browser and the company’s free iPhone app.

Four models have initially been launched, including non-programmable, programmable and time clock versions. All are 230v powered and all offer volt free switching, catering for most types of boilers.

Heating comfort levels, holiday program and temperature hold functions can all be operated and, apart from a wireless router and broadband line, no other equipment is required to gain access to the system remotely.

This range will be extended further in the coming weeks with the release of a wireless switching model – compatible with the UH1-W wireless wiring centre.

Deluge of responses

Nu-Heat is delighted with the response to its rainwater harvesting offer, introduced just over a year ago.

Nu-Heat stocks a selection of Roth systems with the best seller currently being the 5,000L package; 3,500, 7,000L, 10,000L packages complete the range. Nu-Heat believes that the Roth tanks are among the best available due to overall quality and two features in particular.

Firstly, the tanks are low profile so don’t require such as deep installation pit as other models that have more of a goldfish bowl shape. This also means that the tank can be installed in locations with a higher water table. Secondly, the tank is made from a single moulded piece without seams, ensuring integrity and making installation more straightforward as the pieces don’t have to put together on site. The tank is still relatively light for manoeuvring into position.

There is no requirement for a break tank, so no water is stored in the loft, and the only internal installation required is the control unit. Nu-Heat’s unit is comparable to other high spec systems on the market, and pumps water round the system at mains pressure of 3-4 bar.

One major advantage of the control unit is that it measures what is in the tank, so when there has been no rainfall and the level reaches a pre-determined limit, the unit automatically switches to mains water. The control unit includes a 9L storage tank, so unlike other models that flood the rainwater tank with mains water, Nu-Heat’s system only holds 9L of mains water in store, so that if there is sudden rainfall, mains water isn’t used unnecessarily. When there is sufficient rainwater in the tank, the control unit will automatically switch the system back to the tank supply. The display on the control unit indicates the status of the rainwater levels and what mode the system is in.

Nu-Heat has recently added a number of useful accessories available for purchase to widen the potential for installation. The first is a stronger lid which is suitable for tanks being installed under a drive. The lid is able to withstand a 600kg wheel load. As with any tank installation on a drive, a concrete ring must still be put around the lid so that it doesn’t get pushed down when driven over.

A second accessory is a periscope extension. This is for use in situations where a tank needs to be deeper than normal, such as where water needs to travel further from the gutters. The existing periscope is 700mm and the extension is 500mm.

Roth’s rainwater tanks are exclusive in the UK to Nu-Heat.

Daylight scoop

Better aesthetics and performance in natural daylighting is being brought to market with the latest tubular rooflight from Passivent.

The new Passivent Sunscoop features a square, low profile roof dome. The square profile simplifies installation in all roof materials and eliminates the need to create complex flashing detailing inherent with conventional round roof flashings. The low-profile polycarbonate roof glazing improves aesthetics once installed, minimising variations along the roofline without any impact on the amount of natural daylight entering the building below down the highly reflective tube.

A choice of two interior diffusers offers the flexibility to select light distribution according to requirements, be it diffused or a more direct light, whilst optional low energy light fittings incorporated into the diffuser assembly further enable effective lighting even at night without the need for separate electric lighting. In the day, even the 250mm Sunscoop delivers more natural light into the room below than a standard 13W low energy lamp (equivalent to the old style standard 60W bulb), without any electrical consumption.

Passivent is also offering tube insulation to the system, which reduces both the risk of thermal bridging and surface condensation.

“Tubular rooflights such as Sunscoop are already recognised and awarded credits under BREEAM, in both energy and health and wellbeing categories, bringing natural daylight into areas that would otherwise be dark or lit artificially,” Siobhan Gadiot, BPD marketing communications manager, said. “Sunscoop offers specifiers, contractors and end-users more than any other rooflight of its type, as it’s the only one in the market to carry a 25 year guarantee on the reflective tube- the key element.”

Passivent Sunscoop can be fitted in both new-build and refurbishments. Unlike similar products, its flashing are AA fire rated, enabling unrestricted use regardless of the proximity of adjacent buildings. The roof glazing unit is installed in the roofline, while the highly reflective connector tube directs natural daylight down to the ceiling mounted diffuser in the room or corridor below.

More efficient panels

The world’s most efficient solar panels commercially available – as certified by the Guinness World Records – are now available to British homeowners.

US-based SunPower E20 solar panels have signed a deal with the UK solar panel company, Ploughcroft – the solar roof installation partner for Vaillant, Plumb Center (Wolseley) and NPower.

The company is the first in the UK to offer the SunPower E20 panels to British domestic and commercial solar customers.

SunPower E20 panels are designed to offer 8% return on investment, based on the new Feed-in-Tariff (FIT) of 21p per kW. Offering high levels of efficiency in the UK (20%), Ploughcroft claims these solar panels provide more power than any other panel currently available and are sure to appeal to savvy homeowners looking for a great return for their money.

All this extra technology is packed into a standard size panel (1.5m x 1.05m), resulting in a smaller roof space being needed to achieve great returns. Just 12 E20 panels can achieve a 4kW output (the FIT cap level), whereas currently there needs to be 16-20 panels fitted to get this rate.

Chris Hopkins, managing director at Ploughcroft Solar said: “The UK is the world’s fastest growing market for solar technology, and as Ploughcroft is the leading solar installer, then it is fitting that we are able to offer our customers these amazing panels. The ultra efficiency means that even in cloudy or overcast conditions these panels work far better than any other.

“The energy generation is outstanding, and following the recent announcement to cut the FIT rate then these panels are sure to appeal to homeowners looking for a good return on their investment. The E20 panels could quickly become the most popular panel available to homeowners.”

The cell technology within the SunPower E20 panel is now fully Microgeneration Certification Scheme accredited (awarded 28 October 2011) and offers an output of 333w compared to the industry high of 250w.

Chris has recently been appointed to the Green Construction Board (GCB). The GCB consists of government and industry experts who will drive forward the actions set out in the Low Carbon Construction Action Plan.

FITs still an ‘opportunity’

Feed in Tariffs (FITs) still represent a fantastic return on investment, despite the recent reduction announced by the Government, lead generating company Quotatis has claimed.

FITs were launched by the government in April 2010 in a move designed to encourage the widespread domestic installation of photovoltaic panels. To this end the scheme has been very successful – there were more than 16,000 new solar PV installations in September 2011 alone – as homeowners have taken advantage of a generous tariff that paid them 43.3p/kWh for every unit they produced whether they used that energy themselves or sold it back to the grid.

At the end of October 2011, the Department for Energy and Climate Change announced that FITs would be reduced to 21p/kWh for new projects, and homes would have to prove that they are already energy efficient to qualify for the tariff.

“There has been something of a panic following the Government’s announcement to reduce the FITs, which I believe is unjustified,” Teresa Gizzi, Quotatis’s sales director, explained. “FITs make up just a small part of rapidly growing and important industry, and despite people’s fear that it will pull the rug out from beneath it, the opposite is probably true.

“When FITs were launched 18 months ago, the cost of an average PV installation was about £13,000. That figure has dropped to around £9,000 and is still falling. Therefore, homeowners will still get a return of anywhere between 4% and 10% on their investment – far better than what the high street banks are offering! Plus, energy bills will still be lower.”

Teresa went on to explain that looking at the FIT in isolation ignores the many other benefits that energy efficient products bring. “The Government’s other announcement – that homes have to prove a minimum level of energy efficiency before they qualify for FITs – is positive news for industry,” Teresa explained. “You can’t view solar power on its own – generating your own energy is just one piece in a huge jigsaw puzzle of reducing our reliance on fossil fuels. There’s no point in enjoying free electricity when the sun shines, only to whack up the heating when it gets dark.

“Therefore, the industry must work together to educate homeowners on how to save energy by making their homes more efficient, rather than just sell them the sexy shiny panels for their roofs.”

Quotatis was recently endorsed by the Energy Saving Trust to give impartial advice to homeowners on energy saving matters. “This means we can now offer in-depth advice – backed up by the highly respected Energy Saving Trust – on a range of energy saving methods, including double glazing, insulation, replacement boilers and renewable energy,” Teresa said.

“This, in turn, provides opportunities for our business partners. Energy prices are still increasing, and homeowners are looking at a variety of ways to make their homes cheaper to run. They approach us for advice, and any resulting leads are then passed on to our registered team of installers.”

Concluding, Teresa said: “People are not going to lose interest in the energy efficiency of their homes just because FITs have been reduced. Now, more then ever, businesses need to position themselves to make the most of a revolution in sustainable home improvement.”


Fresh new dimension

Vivix panels enable architects or specifiers to create a unique building identity or accentuate its architectural elements with either a ‘bespoke’ or unified design, complementing or adding interest to public, cultural or sports facilities.

Lightweight, resistant to impact and abrasion and UV and weather resistant, Vivix panels are highly resilient against cracking, do not rot, and include double-sided UV protection as standard.

Available in plain colours with sophisticated neutrals and striking accents, nature-inspired abstract patterns and rich woodgrains, Vivix panels can be installed on top of an existing facade, bringing a fresh new dimension and improved performance efficiency to an existing building.

Panels from the Vivix range can be used with a variety of fixing systems, from simple timber battens to proprietary metal systems and hung by visible face-fixing or by concealed fixing arrangements depending on the aesthetic requirement.

Certified as low-emitting by GreenGuard Environmental Institute, Vivix panels incorporate Formica Group’s commitment to sustainable principles and practices.

Official authorisation

The German Institute for Construction Technology has given BASF's Styrodur 3035 CS, Styrodur 4000 CS and Styrodur 5000 CS technical approval for multiple layers as perimeter insulation in groundwater [no. Z-23.5-223].

The XPS (extruded plystyrene) boards can be used for multiple layers of external insulation for structural components in contact with the ground (perimeter insulation).

Previously, only a single layer of XPS in the perimeter insulation was approved. The approval makes it easier for the construction companies carrying out the work to use the insulating materials and makes it possible to meet the increasingly stringent energy requirements on new buildings.

This means that BASF now has approvals from the Institute to install multiple layers of Styrodur C for foundation slabs, inverted roofs and perimeter insulation.

Perimeter insulation reduces heat loss at the bottom of a building. Styrodur C is good for perimeter insulation because of its high compressive strength and low water absorption due to its closed cell foam structure and foam skin on both sides. Up to three layers of the insulating material can now be used under non-load-bearing foundation slabs and on basement walls at a total thickness of up to 400mm. Styrodur C can be immersed up to a depth of 3.5m in groundwater.


New members hit the floor

Carpet & Flooring, a UK distributor of floorcovering products, is the latest member to join Recofloor and increase the number of strategic collection points for the UK’s award-winning vinyl flooring recycling scheme.

Established in 1973, Carpet & Flooring has grown into one of the largest distributors, stocking and distributing products from Europe’s leading manufacturers as well as its own domestic and contract floorcovering brands.

Having successfully piloted the Recofloor scheme at its Birmingham branch in August, Carpet & Flooring has now rolled it out to the remaining seven branches across the country.

“I am delighted that Carpet & Flooring is now participating within the Recofloor Vinyl Take Back Scheme through our national network of branches,” managing director Paul Gordon, said.

“The scheme fits perfectly within the company’s environmental objectives and targets, while providing an opportunity to assist our customers with the segregation and recycling of vinyl and safety flooring to maximise waste diverted from landfill.”

Recofloor bins accepting waste vinyl off-cuts and waste smooth uplifted vinyl flooring are now located at all their depots in Bristol, Bow, Camberley, Cambridge, Gateshead, Glasgow and Manchester.

Flooring contractors and installers can also collect polythene bags from the trade counters for their waste material. When full, these can be left at the depots from where they are sent for eventual recycling into new flooring and traffic management products.
