New teaching accommodation guide

Foremans Relocatable Building Systems, UK supplier of recycled and refurbished modular buildings, has published a new report – ‘A Guide to Expanding Teaching Accommodation’.

This latest in a series of reports and technical papers from Foremans provides education professionals with a comprehensive guide to procuring a modular building and can be downloaded from the Foremans website – www.foremansbuildings.info/industryreports. It gives 23 practical tips to help schools avoid some of the most common pitfalls, and to help ensure modular building projects are completed on time, on budget and to the required quality standards.

The new paper provides clear guidance about how to expand teaching accommodation using off-site construction, quickly and efficiently, for the smooth running of each building project. Areas to consider include:

• Key decisions to take in the planning stages to ensure clarity and focus for the project team
• Advice on obtaining planning permissions
• The complexities of project management
• How to ensure the modular building meets the relevant guidelines and legislation
• How to set the design criteria
• What to look for when selecting a modular building supplier.

Kevin Jones, managing director of Foremans, said: “Modular teaching accommodation offers a host of benefits for schools and LEAs, whether the building is for interim or permanent use, to meet place planning requirements, or to upgrade or expand school or college facilities.

“The speed of delivery is important, as is the need to minimise disruption to teaching. However, it is also vital that every school building project is completed on time, on budget and to specification.

“This report shares our team’s experience and expertise to help education professionals avoid some of the most common mistakes and to choose the right modular building partner for their project. Building users need to be aware that not all suppliers are the same – whether they specialise in new manufacture or recycled modular buildings – and not all will be able to provide the services required for a particular project.”

The use of recycled and refurbished modular buildings continues to increase as more schools, colleges and LEAs recognise the advantages of this highly innovative solution to providing new and purpose-designed teaching accommodation.

Pre-owned modular buildings can reduce programme times by up to 70% and are a highly cost-effective alternative to new build and new manufacture – an important benefit in the current economic climate where budgets are severely restricted.

This is also one of the most sustainable methods of construction – helping to reduce carbon emissions, waste sent to landfill, and improve a building’s carbon footprint.

Smart heat recovery

Achieving 0.47W/l/s, with 93% heat transfer, and incorporating new Greenwood Smart Technology, the new Fusion HRV2HT takes one of the UK’s best performing heat recovery product to the next level.

Assisting in the delivery of GIP (Guaranteed Installed Performance), new Greenwood CommissionSmart technology provides a fuss-free method of commissioning.

Smarter thanks to wireless technology, one single and simple to operate LCD controller can be used to set up, adjust and commission numerous units on-site, helping save valuable time, as the installer does not need to keep going back to the unit to make adjustment.

One hundred percent variable airflow settings ensure Fusion HRV2HT meets Building Regulation requirements on-site first time. Ensuring year-round comfort for homeowners Fusion HRV2HT also boasts Greenwood SummerSmart and Greenwood WinterSmart technologies. Providing an intuitive response to seasonal variations they sense the outside temperature and automatically make changes to the way in which the supply air is delivered into the dwelling to create the perfect indoor climate all year round.

Additional Smart features and technology improve the overall energy efficiency and performance of Fusion HRV2HT. Greenwood HumidiSmart, a new way of using humidity to provide ventilation into domestic dwellings, reacts only to man-made humidity rather than a preset generic setting, and Greenwood TimerSmart measures the duration of occupancy to determine run time. Both technologies help remove nuisance running noise and reduce unnecessary energy wastage and heat loss throughout the year in the home.


Humidity regulating foil

Free solar energy

Oxford Sustainable Group, a European independent renewable energy and sustainable development businesses, has launched Sol et Libre in the UK – a second-generation 'free solar' business.

Sol et Libre is offering free solar installations plus cash payments to domestic and commercial property owners located in the south of England. The Oxford Sustainable Group is an experienced developer and investor in the UK solar market having funded and developed ISIS Solar (the UK free solar brand) from scratch.

Sol et Libre will now enable its customers to benefit from annual savings on their electricity bills, typically around £360 for the average domestic property at today's electricity prices, and receive £250 cash.

Sol et Libre customers will save on the upfront cost of the solar installation, which is around £15,000 for most residential properties. In return, Sol et Libre will benefit from the Feed-In Tariff payments.

"Oxford has been highly successful with solar, wind and biomass across Europe," said Robin Paine, director, Sol et Libre. "We want to repeat that success with Sol et Libre and help to grow the production of renewable energy in the South of the UK. We're offering a great deal – free electricity and an initial cashback payment of £250 – this is a first on the market and is proving to be very attractive to our customers.

"Our aim is to install 50MW of solar modules by summer 2012 and with the Oxford Sustainable Group behind us, we have the knowhow and finance required. Beyond that, we want to develop more broadly in both commercial and community solar projects in the South of England. We are happy to hear from people with suitable domestic and commercial properties and community projects."

Oxford Sustainable Group, Sol et Libre's parent company, has over 800MW of renewable energy projects in development across Europe. It has more experience of operating free solar business models than any other UK company, having completed the full lifecycle of solar development and is now on its second-generation company.

Kits with different output sizes will be available in the near future. To give customers complete peace of mind, all Schueco components carry written guarantees and warranties.

Installers can place an order either by telephone (01908 289185 or 289177) or by fax (01908 289123), quoting article no 272 732. There is also a dedicated technical helpline (01908 289188) to deal with queries and to provide information.


Door to energy efficiency

Sheerframe offers fabricators and installers a bi-fold door system capable of delivering future-proof energy performance with U-values as low as 0.8W/m2K.

The current Building Regulations Part L allows for bi-fold doors with minimum U-values of 1.8W/m2K, which means door-sets with 1.4 to 1.8W/m2K U-values are typically available in the marketplace. However, this could mean the bi-fold doors are the energy efficiency weak-spot in the building fabric as the surrounding wall into which the doors are fitted offers a much better thermal performance – new ICF housing for example from market leader ICF Tech achieves 0.15W/m2K as standard.

Future Building Regulations may also lower the 1.8W/m2K U-value for doors limit in 2013 and 2016 as the zero carbon homes and PassivHaus standards already demand a 0.8 maximum.

Sheerframe marketing director David Strang said: “Given the serious investment that homeowners make when they choose to install bi-fold doors, it’s crucial that they have access to the most energy efficient option. The thermal performance of homes is only going to get more important and this coming winter is looking likely to bring a financial shock when gas and electricity bills arrive.

“With the Sheerframe bi-fold door system achieving a 0.8 U-value, fabricators and installers have a proposition that any serious customer will warm to. Replacing a large section of their exterior wall with a stylish door-set that will help them save money on heating is a fantastic selling point, and one which other bi-fold doors on the market will struggle to beat.”

Manufactured in the UK from 100% lead-free PVC by LB Plastics, the Sheerframe bi-fold door profile features five chambers for minimal heat transmission through the frame and the system accommodates 44mm triple glazed units as standard. The thermal properties are enhanced by its four interlocking weatherseals which ensure air and weather tightness.

Exceptional air-tightness results of 300 pascals, matching the maximum category for air tightness in doors to BS6375 Part 1 2009, are achieved by the new range. Water tightness results show performance to 600 pascals, way above the 100 pascals required fro BS (Class 3A).


New triple glazed bead

Swish Window and Door Systems has launched new triple glazed bead options capable of achieving U-values as low as 0.8W/m2K.

Developed to support commercial fabricators in winning business in the new build sector, the triple glazed bead allows specifiers to achieve Code Level 6 and beyond.

Swish is also pitching the triple-glazed system at retail sector where the Epwin Group systems house argues it supports sales by giving installation businesses a tangible point of difference.

Rob McGlennon, divisional sales director, at Swish parent Epwin Group Extruded Products division, said: “Clearly it enjoys significant appeal in the commercial sector but equally its appeal in retail shouldn’t be underestimated.

“It’s something that is tangible – consumers can see a third pane in a way that they can’t see low iron glass or argon gas, even though those elements are far more important in increasing thermal performance.”

The triple glazed bead option means that the Swish system can accommodate a 44mm triple glazed unit. Fully tested on the industry standard side hung fixed combination 1230mm by 1480mm window, development also included hardware trials and full opening/closing cycle testing.

Lawson Price, divisional technical sales manager, Epwin Group Extruded Products Division, said: “The fact that the product has been tested against an industry standard window, rather than a product that has been ‘manipulated’ to achieve a certain level of performance is significant.

“For example, window styles and dimensions can be adjusted to increase the size of the glazed area to artificially ‘bump up’ performance to support headline sales claims.

“By contrast in testing a window made to an industry standard specification we know that it will deliver across a broad range of specifications and that eliminates complexities and delay at the fabrication stage.”


Warm tie

Ancon’s range of low thermal conductivity wall ties minimise heat loss through thermal bridging, improving the energy efficiency of a masonry cavity wall.

The use of these ties can reduce insulation depth and wall footprint.

In addition to a number of stainless steel wire wall ties, the range includes the Ancon TeploTie which is manufactured from pultruded basalt fibres set in resin. This BBA-approved product is available exclusively from Ancon. It has a thermal conductivity of just 0.7W/mK, making it the most thermally efficient wall tie on the market, the company claimed.

It has already been used on the first certified Passivhaus to be built with traditional masonry cavity walls and the first retrofit to be built to Level 6 (Zero Carbon) of the Code for Sustainable Homes.

Ancon now has a BBA-approved, low conductivity wall tie for cavities from 50mm to 300mm.


Tackling VOCs

Fermacell is a modern building which can help improve the overall BREEAM rating of a building.

A new product called Greenline was launched by Fermacell at Ecobuild and effectively tackles VOCs. The main difference between Greenline and standard Fermacell high performance dry lining boards is the addition of a natural additive that absorbs VOCs leaching out of compounds as gases.

Fermacell is a multi-purpose board providing high acoustic, fire, moisture, impact resistance and excellent racking strength properties.


On cue for recycling

Snooker legend Steve Davis gained another winning frame when he called in on Network Veka fabricator Glazerite Windows to find out about recycled PVC-U windows.

The six-times World Champion had set out to learn hands-on every step of the recycling process for a consumer DVD and dropped in on Glazerite’s North West division in Bolton to help make a window from Veka’s Infinity recycled profile.

Steve was filmed through every stage of fabricating the frame before declaring it “a new kind of window for a new generation of homeowner”.

Recently, Glazerite made the first ever recycled window to go into a UK private house. In the final DVD, produced by Network Veka, Steve will be seen helping to install that window before following the journey of one old frame all the way through Veka Recycling in Kent to Veka in Burnley, where the Infinity system was conceived and is made, then on to Glazerite.

Infinity uses a co-extrusion process where pure recycled PVC-U is locked inside a thin outer wall of virgin polymer, making it nearly 80% recycled material in total and with only a third the carbon footprint of a conventional window.

The Infinity system is fully compatible with the existing Matrix 70mm range and available on a standard five-day lead time. Glazerite is confident the profile will appeal to environmentally conscious homeowners and commercial specifiers alike – both expanding markets – as well as demonstrating considerable corporate social responsibility and commitment to the environment.


Underpinning success

Low-carbon energy company, LowC Communities, has underpinned its recent progress with the appointment of Jane Mellor to the role of finance director.

Based at its headquarters in Stamford, the company specialises in the design, construction and operation of renewable energy infrastructure for public and private-sector buildings. Launched in 2007, LowC has become known in the energy sector.

Richard Griffin, managing director, said: “We are really pleased to welcome Jane into her new role at LowC. Her qualifications and experience will be vitally important as our company continues to implement its strategy for growth.

“With irrefutable evidence of climate change hitting the headlines and our Government having signed up to internationally binding targets to reduce global carbon emissions, LowC’s offering is becoming ever-more relevant. Jane will be a key part of the team and we are all looking forward to working with her.”

Jane had previously run her own accountancy practice, after a 19-year stint with the American-owned, Liant Software. Having worked her way up to the dual role of managing and finance director, Jane was responsible for a turnover of £3m and a team of 13 staff covering Europe, Middle East, Africa and parts of Asia.


Super efficient doors

Solarlux has launched its most efficient glass door to the UK market.

Combining four core elements that enable the door to achieve a U-value of 0.80Wm2K, the new SL97 wood/aluminium folding glass door is specially designed with the demands of energy saving in mind.

By using wood internally and a combination of insulating material and protective aluminium externally as well as triple glazing, the SL 97 has been able to combine the advantages of four materials.

Inside, the wood panels create a natural warm atmosphere and, on the outside, the fully insulated rear-ventilated aluminium facing sheets guarantee permanent protection from the elements with only minimal maintenance. The company envisages applications both in luxurious private homes and multi-storey high-quality rented and owner-occupied flats.


Sustainable alternative

Timbmet, one of Europe's leading timber distributors, and the UK's exclusive supplier of Red Grandis, a Pure Forest Stewardship Council (FSC) red hardwood, is to offer a legal and sustainable alternative to Sapele or Meranti timber.

The introduction of Red Grandis demonstrates how a new plantation-grown species with Pure FSC certification can be brought to the market with customer benefits in terms of sustainability, natural durability, ease of use and continuity of supply – particularly important given ever increasing global demands on timber as a natural resource.

A high-grade clear timber delivering consistency of colour, appearance, grain and workability, Red Grandis – or Eucalyptus grandis, to give it its generic name – is most often used in the production of internal mouldings, including skirting, architrave and thresholds, furniture, cabinets and exterior cladding profiles, as well as within the window and door frame industry.

Red Grandis has undergone independent third-party testing by Trada Technology and Building Research Establishment, achieving great results for natural durability and resistance to fungi – key for long-term performance – as well as Class D35 for strength and stiffness, and Class C35 for density to prove its suitability for joinery and structural use.

Under the plantation growing process, intensive pruning is carried out to provide a knot-free, clear, uniform timber with sapling thinning to enable the trees to reach significant diameters. It is easy to machine and shape, and because all lengths are identical, there is less waste and reduced production time, as well as a much better finish overall.


Warm roof

In a bid to provide a more cost effective and thermally efficient alternative to solid roofs, and which escapes local authority ‘red tape’, Ultraframe has developed Utopia, a new style of double layered conservatory roof technology which has been designed to dramatically improve a roof’s U-value and extend the use of a conservatory to 365 days a year.

Using fully thermally broken integrated support extrusions, Ultraframe’s Utopia eco roof features two layers of polycarbonate, 35mm Heat Guard Opal externally and 32mm Opal internally, along with an internal chambered ‘T’ cladding and a chambered ridge undercladding.

The centre pane U-value of the two sheets of polycarbonate is just 0.6, producing a conservatory roof that requires only 788kWh of heating energy a year, 1300kWh less than the average and saving the average household at least £200 on heating their conservatory.

Andrew Thomson, technical director at Ultraframe, said: “It’s common knowledge that conservatories can often overheat in summer and become too cold in winter, making them uncomfortable to sit in. The reason for this is that in summer, most conservatories simply don’t reflect the heat and end up overheating, while in winter, the roof’s low insulation value can become a problem.

“Traditionally, homeowners have looked to combat this and achieve lower U-values by retrofitting a solid roof and turning the conservatory into an extension, which can often mean doubling the cost and obtaining Building Regulation approval.

“As the industry leader in conservatory roofs, we knew we had to develop a new technology which would improve the U-value of a conservatory roof and allow consumers to enjoy their conservatory 365 days a year, come rain or shine.”

Until now, conservatory roofs have been designed with a single layer of polycarbonate or a double glazed sealed unit, resulting in an average U-value between 1.1 and 1.7. By adding another layer of polycarbonate, Ultraframe’s next generation roof solution can achieve a centre pane U-value of 0.6 and save homeowners hundreds of pounds on their heating and energy bills, as well as increasing winter usage of the area.

Andrew continued: “By installing a Utopia system as opposed to a solid roof extension, consumers are able to enjoy the benefits of light and space that come with a conservatory.”

Manufactured with heatguard externally and opal polycarbonate internally, sunlight is better reflected off the Utopia roof, extending the number of hours homeowners can use their conservatories in the summer months. In addition, the double layer polycarbonate also acts as a great barrier to noise transmission, reducing disturbance from outside sources.


New triple glazing

Network Veka fabricator, Blair Neill, has launched a triple glazed PVCU window with a U-value of just 0.8Wm2/K

“We want to give customers something better than A rated windows,” said Peter Blair, MD of Blair Neill. “Rising heating costs are a continuing worry for homeowners and they are looking for new ways to keep bills down. So we’re launching a window that meets the U-value of Passivhaus standards for windows giving installers a real advantage over competitors.

“The frame is insulated with a foam thermal-core and combined with the triple glazing gives a window with just 0.8 U-value and the good looks of a PVCU frame.

“The benefits of the new window are easy to show homeowners with a brochure dedicated to EnviroHome.

“Adding new products and marketing support through EnviroHome is just part of a substantial investment programme for our customers. We know it’s a tough market that’s why we’ve put everything possible into making it easier for customers to sell more. These additions ensure that Blair Neill continues to lead the market for professional installers.”

‘Advanced’ window

Pioneer Trading has launched the Signature High Performance Window.

The company’s managing director Danny Williams claims it is ‘the most advanced window available in the market’.

Pioneers has developed the sash to accept both triple and double glazed units. Danny said: “When I designed this sash it was with the future firmly in mind. It has been clear for some time that the present Window Energy Ratings maximum can be relatively easily exceeded and future advances in performance would require triple glazing. We took that into consideration and we have a window that can accept triple glazed units without modification, in addition to relatively low specification glazing units that will still achieve an A rating. Our claim will stand the test: this is the most advanced frame you can buy today.”

The sash incorporates a sophisticated cell structure that allows the production of a C Rated frame with a standard IGU, and an A Rating with the simple addition of a warm edge spacer – no argon required. The preclusion of expensive low iron glass for even the highest WER alleviates the problem with condensation associated with this type of glass.

Use of a fully specified IGU promotes performance of the Signature Sash to an A+30 rating.

The Signature High Performance Window offers a slimmer section providing a significantly greater glass area, important when replacing smaller windows and frames such as bays. Weight and cost is reduced as steel reinforcement is minimised and the super-stiff profile has extra screw porting for significantly better location of hardware; this significantly improves the security of the sash.

The rigidity allows a wider span for the sash, from the assumed maximum for PVCU of 600mm, to 700mm. Fitting is also easier with the bead ‘especially slippery’ to ensure it drops into place securely with minimal effort and fuss.

Heating evolution

A new highly efficient woodburning stove that incorporates a boiler to generate hot water for central heating and can be connected directly to a sealed heating system as well as plumbed conventionally on an open system has been launched by Broseley Fires.

Like all stoves in the company's eVolution range, the new eVolution 8 combines eco friendly features with a contemporary design and the latest in stove technology, including the Safety Cold Water System (SCWS) which was pioneered by Broseley Fires.

SCWS enables Broseley’s solid fuel boilers to be fitted onto new or existing sealed central heating systems without the need for additional pipework and controls to vent the boiler. The eVolution 8 system can easily link up with other boilers or heat sources such as solar panels or ground source heat pumps through connection via a thermal store or low loss header.

The eVolution 8 boiler stove was developed by Broseley to meet the growing demand in Europe and the UK for highly insulated, air-sealed housing and sealed heating systems. The system means that, for the first time, a wood-burning boiler can be seamlessly integrated into an existing sealed heating system, including combi boilers, with no additional expansion tanks or unsightly pipework.

The eVolution 8 is a free standing stove which is designed to maximise convection heat output from all working surfaces. The huge 400mm x 300mm glass panel has a door designed for a crisp, quality closure and is kept clear with a pre-heated air wash offering high visibility of the flames. The slimline design is finished in grey painted steel and has a nominal heat output of 11kw, 8kw to water and 3kw to room, and is one of the most efficient in the industry operating at 83% efficiency.


Seasonally efficient chiller

Daikin Europe has introduced EWAD~CZ air-cooled inverter chiller range with the highest ESEER (European Seasonal Energy Efficiency Ratio) in the market – up to 6 (with optional fan speed regulation) making it a highly cost-effective solution for use in comfort cooling and other applications where a high quality chiller in terms of performance and reliability is needed. Highest partial load efficiency: ESEER up to 6.

The use of inverter driven screw compressors in the EWAD~CZ range allows units to achieve the highest partial load efficiency levels in their class, making them ideal for systems with variable load requirements such as comfort applications. The high partial load efficiency of these solutions allows substantially reduced CO2 emissions and decreased annual operating costs with attendant reductions in payback times.

The use of inverter technology also contributes to quieter sound levels and precise chiller water temperatures, as well as lower starting current requirements, optimum power factors (always above 0.95), a reduction of water tanks for the hydraulic system and increased reliability due to fewer compressor start-ups and shut-downs.

Inverter control is complemented by a host of other advanced features such as a patented single screw compressor, and ultra efficient fans with a patented blade profile for quiet operation. Furthermore, the new Microtech III controller allows easy control of performance parameters, and a wide range of system integration solutions are supported including LonWorks and BACnet.


Cladding includes PV modules

New from Schueco UK is SCC 60 with ProSol TF, a cladding system for the side of buildings and other structures, purpose-designed for use with ProSol TF thin-film PV modules.

The resulting ventilated facade is multi-functional and can provide weather protection, excellent insulation and sustainable energy production all in one package.

In addition to the cladding system and PV modules, Schueco also supplies all the additional components, known as the BOS (Balance of System), such as wiring, connectors, inverters etc that are needed to achieve an optimum system configuration and low system losses.

ProSol TF modules use amorphous thin-film technology, the key advantages of which are a more effective use of the light spectrum and a low level of dependence on temperature compared to crystalline products. Energy is therefore produced even in cloudy or twilight conditions enabling the system to achieve the highest possible output per installed Kwp.

Modules can be up to 2.6m wide x 2.2m high, but the use of Schueco’s fixed-size module measuring 1.3m wide x 1.1m high offers substantial economic benefits.

Many types of buildings in both the private and public sectors can benefit from Schueco SCC 60 with ProSol TF including multi-storey flats and offices, warehouses, industrial buildings, hospitals and colleges. Moreover, since it is ideal for retro-fitting, the system can be used to rejuvenate old buildings by improving their energy balance, cutting CO2 emissions and equipping them with a new income stream.
