Independent specification tool for metal roofs and facades free to users combined
Story

www.metalinfo.co.uk has been launched to provide the first independent source of reference for specifiers of zinc, stainless steel, copper and aluminium roofing and faÇade systems. The site actively promotes the use of hard metals and has been designed to simplify the design and installation process by making detail drawings and build-up information for inclusion in contract documentation available in an industry-recognised format. The service can be used either on site via a mobile device or in the office.
Metal roofing and faÇade systems attract an understandably high level of interest among specifiers given the critical contribution they make to the aesthetics and functionality of any building envelope. With so many subtle variations in colour, texture, finish and application technique, the availability of a single source of information which is not linked to any manufacturer is already proving to be an invaluable specification tool.
Users need no longer search for information and register with individual manufacturers' websites, so product comparison is easier and downloading of essential information far quicker. Only an e-mail address is required rather than lengthy registration, after which drawings can be sourced using a simple search tool and previewed prior to downloading.
The site includes a comprehensive listing of manufacturers, distributors and installers with contact details and web links. To view an introductory video on the site go to www.metalinfo.co.uk/video.html

WILO KEEPS WATER AT BAY FROM UNDERGROUND STATIONS
Story


For many years, Wilo UK has been supplying submersible pumps to customers across Europe. In the UK, these hardworking, high quality pumps have been keeping water at bay in a wide range of applications that day to day attract little attention, but keep buildings, and people dry by removing water from where it's not wanted.
Network Rail has a number of stations that are underground and below the level of rivers that flow close to the rail tracks. To keep them safe and operational, a constant flow of water is required to be pumped away from the stations and away from tracks. Mersey Rail in the north west is one such application. Several stations are located underground and for many years submersible pumps have been managing to keep the water away from the public areas and the tracks, but the existing pumps had been failing increasingly regularly due to corrosion and wear. Network Rail was looking for something different that would replace the failing pumps but maintain their performance in difficult circumstances, and not cause problems on a fairly regular basis.
Step forward Sean Fearn from Wilo UK, who recommended the Wilo EMU NK87 submersible borehole pump for the job. Able to shift the volume of water required, these clever pumps offer a self-cooling design and simple installation, but importantly come with a Ceram CT coating which increases their effectiveness and ensures reduced wear and counteracts corrosion. Several months after installation, they are performing perfectly.
Sally Whitter from JP Whitter the contractor on the Mersey Rail project says these pumps have done the job required: “We put six of the pumps in back in the summer of 2013 and they've been doing the job excellently. In the past we've had some emergency situations where a pump has gone down and we've had to replace it at short notice to keep the water level down. Replacing a pump is a pretty major task €“ it's not just a case of pulling it out and popping a new one in €“ it's a complex procedure, so we don't want that happening too often! Since the Wilo pumps have gone in, we've had no emergency situations at all and the underground part of the Mersey Rail system has functioned perfectly.”
Simon Oakes is Sales Director €“ Water Management for Wilo UK: “This is an excellent example of where the pumps we can offer can both do the job they are specified for and offer that little bit extra. Clever technology linked to the standard offering from the pumps means that we can offer pumps that perform well, but which importantly offer longevity and resist wear and corrosion as well. This is what our customers are looking for from us and Network Rail has been delighted with the performance they are seeing from the first pumps of this type they have taken from us. There are a myriad of applications requiring a similar approach and we're talking to many companies and organisations that are impressed by what we can offer, proven by the results we have achieved on the Mersey Rail project.”

Daikin Europe increases use of green energy with solar panels at Ostend plant
Story

Daikin Europe N.V. has added to its green energy bank by the installation of almost 2,000 solar panels at its Ostend, Belgium production plant. Designed to produce around 400,000 kW electricity per year (the equivalent consumption of 115 households), the system went on stream at the end of August and the energy generated will help power Daikin’s on-site operations.
Daikin Europe originally considered the use of solar panels some five years ago but since the efficiency of the then available technology was inadequate, purchased green electricity on the market, reducing its environmental footprint and resulting in a drastic reduction of CO2 emissions. However, solar panel efficiency has improved considerably and the decision to install panels was examined again and approved in 2010. Work began at the end of April and the system became operational at the end of August.
The deployment of solar panels is very much in line with the overall environmental policy of the company and its intention to decrease dependence on electricity suppliers and the choice of solar panels was taken after considering other solutions including wind turbines. The installation will result in a yearly savings of up to 160 tonnes of CO2. System capacity of 400,000 kW per year was dictated by limitations in the region’s electricity grid due to the high number of renewable systems already in place.
The solar panels are located on certain plant roofs at Ostend site and to highlight the effort and increase environmental awareness the performance of the installation will be visible via screens in the factory and reception area. Real time data will include daily energy production, CO2 saved and comparisons with previous periods. Minimum life of the installation is 20 years but actual life is expected to be 30-40 years.
Daikin Europe N.V. announces the expansion of its Daikin Altherma heat pump range to cover large-scale commercial applications in which space heating and hot water production are a priority. Due to the use of Daikin Altherma cascade technology, large volumes of hot water (with temperatures up to 80°C) can be produced efficiently, making the system ideal for applications with a high demand for space heating and/or hot water heating.
Large capacity hot water production for the commercial market
The optimised Daikin Altherma Flex Type series produces leaving water temperatures from 25° to 80°C, making it suitable for all types of radiators, under floor heating, fan coil units, heat pump convectors as well as hot water production. Typical applications include hotels, fitness centres, spa facilities, hospitals, libraries and schools. The high leaving water temperatures also make it ideal for upgrading existing heating systems, allowing retention of existing high temperature radiators.
The use of Daikin Altherma cascade technology: two refrigerants – R-410A and R-134a – in a cascade configuration, enables the system’s high leaving water temperatures to be produced without an electric heater. The outdoor unit elevates the temperature and pressure level of the first refrigerant cycle (R-410A) and the indoor units raise this to even higher levels with the second refrigerant cycle (R-134a), resulting in water temperatures up to 80°C using only heat pump technology.
Hot water temperatures up to 75°C result in highly efficient hot water production with rapid heat-up times and the system can be connected to Daikin hot water tanks as well as to (existing) 3rd party tanks. Daikin solar heating can also be integrated for even greater efficiency.
Low running costs
Daikin Altherma cascade technology, in combination with inverter controlled compressors and weather dependant temperature control, results in extremely efficient operation. Running costs can be up to 36% less than comparable oil or gas installations, with up to 35% less primary energy use and up to 71% less CO2 emissions.
Furthermore, optimal dimensioning further enhances efficiency, the system’s modular construction and several different capacity classes of indoor and outdoor units allowing precise configuration for specific needs. The indoor and outdoor units are compact and lightweight, for quick, flexible installation.
The Daikin Altherma Flex Type units extend the existing Daikin Altherma range of low temperature and high temperature systems intended for individual houses and apartment blocks.
Daikin Europe products are distributed in the UK by Daikin Airconditioning UK Ltd and Space Airconditioning plc.

The AMZ Solar awning blind – 21st century technology and styling combined
Story

FAKRO's new generation of contemporary awning blinds includes the AMZ Solar which, in addition to being solar-powered, is also activated by photovoltaic sensor. It is around 8 times more effective than an internal blind in terms of passive heat reduction while still allowing light through. In addition to preventing heat absorption, the AMZ Solar opens automatically in cloudy weather to increase availability of natural light. In winter, it reduces noise from rain and hail and protects the window from accumulation of snow and leaves.
The blind's construction ensures that the correct fabric tension is maintained between guides, enabling it to withstand gusts of up to 120 km/hr and lateral winds of up to 220 km/hr.
The AMZ Solar can be operated either automatically or by using the remote which is supplied for complete flexibility in terms of positioning. It can also be supplied for use within a Z-Wave system.

Heavyweight newcomer floors competition with strength and flexibility
Story

Power and data delivery specialist Marshall-Tufflex has beefed up its Underfloor to Desk range with the launch of a new raised floor box strong enough to withstand the combined weight of ten baby elephants.
The new box is quicker and easier to install and comes as standard with a market-leading 3mm support plate allowing it to handle ‘medium load’ traffic. For installations requiring ‘heavy load’ classification a steel sub-frame can be ordered and quickly inserted (at a later date if building usage changes) to support the lid without restricting space for wiring and accessories.
During load testing this steel sub-frame, which also allows for fine adjustments to accommodate uneven flooring, proved itself capable of withstanding a 1.25 tonne load – more than the combined weight of 10 newborn elephants.
In addition, the floor box has been designed with earth fixing points at each end, giving installers greater flexibility when positioning sockets. It is supplied with dividers that make it suitable for use as either a three or four compartment box.
“Our aim when designing this floor box was quite simple, to provide installers with one product that meets a wider range of needs, offers more flexible installation and can be upgraded to increase load capacity as required. Earth fixing points at either end solve the problem of modifying boxes on site (saving time) and the compartment dividers simply drop in to give either a three or four compartment unit, massively simplifying the specification and ordering process,” said Jeremy Dodge, Marshall-Tufflex Head of Marketing & Technical Services.
The 83mm deep unit, which replaces existing Marshall-Tufflex floor boxes URF32/URF42, is supplied with two easy fit cable retainers/guides, a cut-out within lid for carpet/carpet tiles of up to 6mm deep (extra deep lids are also available), metal screws to attach trim to surrounding carpet for a more secure fix, pre-punched fixings, a barrel lock option for extra security (installer to fit), other box depths, an RCD option and pre-wired option with MT32 Connectors.
The floor box has been designed and manufactured in accordance with the latest standards (BS EN 61534-22:2009, BS EN 60670-1:2005, BS EN 60670-23:2008, BS EN 50085-1:2005 and BS EN 50085-2-2:2008).

A New Source Of Renewable Information For Architecture
Story
The country’s architects have access to a new information source on renewable technology with the installation of a permanent exhibition stand at the Building Centre in London’s Store Street from Mitsubishi Electric which focuses on sustainability in the built-environment.
The company, which has long pioneered energy efficiency in our buildings, is using the space to highlight the potential that heat pumps offer in reducing the energy load required to heat, cool and ventilate both commercial and residential properties, and is also focusing on the energy producing potential of Photovoltaic panels.
“The Building Centre is renowned for providing essential information for all involved in the built environment, so it made perfect sense for us to use this venue to convey the energy saving potential of these technologies,” explained Sharon Oliver, Marketing Communications Manager for Mitsubishi Electric’s Photovoltaic and Domestic Heating Divisions.
Both air source and ground source heat pumps are classified as renewable technology by both the European Union and the UK Government because they harvest free, renewable energy from the air to maximise efficiency and minimise energy consumption.
Mitsubishi Electric has led the way in the use of heat pumps for commercial air conditioning and has pioneered air source heat pumps for both domestic and commercial heating systems.
The permanent stand at the Building Centre includes a touch screen panel which provides essential information on the technologies and highlights how their energy saving potential can be used to meet the Code for Sustainable Homes and other energy performance legislation. In addition to gaining advice on reducing energy costs and emissions levels, architects can also source information on equipment to help with indoor air quality and ventilation.
“Everyone involved in the construction industry, whether new-built or retro-fit is under immense pressure to demonstrate how low carbon the buildings they design now are and we wanted to raise awareness of the potential that this equipment can offer,” adds Oliver.
The Building Centre – established in 1931 – has developed to become an independent forum dedicated to providing information and inspiration to all sectors of the built environment. It is open from 9:30am – 6pm, Monday to Friday and on Saturday’s from 10:00am to 5:00pm. Further information can be sourced by visiting www.buildingcentre.co.uk.

New BBA Rig Tests for CE Marking
Story

The BBA has just taken delivery of a new rig which tests the hygrothermal performance of solid wall insulation systems called external thermal insulation composite systems (ETICS) to the European Technical Approval Guideline (ETAG) 004. ETICS are external wall insulation systems (EWIS) comprising insulation coated with render. The new rig is extremely versatile and can meet the requirements of a number of different test specifications.
The ETAG 004 test regime involves subjecting an insulated solid wall to a series of extreme temperature cycles. This tests how the insulation system will react over time to changes in moisture (humidity) and temperature. The tests and assessment methods outlined in ETAG 004 have been written with an intended working life of 25 years in mind.
The test regime subjects the insulation system to repeated cycles of heat and rain, then heat and cold, and finally heat, rain, freeze and thaw. These cycles are completed in strict order for a set amount of time. During these series of cycles the system can be exposed to temperatures as high as 70°C and as low as -15°C mimicking the extreme weather conditions the insulation system could face during its expected working life. Once complete the test wall is assessed for damage such as surface blisters, flaking, delamination, cracks and other visible changes.
Although mainly aimed at ETICS, other materials such as cement particle boards, glass reinforced plastic (GRP) and MgO boards can also be tested.
The new rig is a significant investment by the BBA and it has been made to address the growth of interest in hygrothermal testing of external wall insulation systems due, in part, to the ability to CE mark this type of insulation system. Although CE marking remains voluntary, for products that do not fall within the scope of a harmonized European Standard (hEN), a manufacturer can obtain CE marking through assessment against the appropriate European Technical Assessment (ETA) and a system of assessment and verification of constancy of performance procedure.
The ETAG 004 hygrothermal test is significantly shorter than other similar tests and coupled with the improved efficiency and versatility of the new rig, cycle times are significantly reduced compared to the test rigs previously used by the BBA. This means a quicker throughput of work increasing the capacity to cope with the anticipated higher level of demand. However, companies are advised to contact the BBA as soon as possible to ensure their products can be scheduled for testing in plenty of time.
To contact the BBA e-mail testing@bba.star.co.uk or telephone 01923 665300.

Permo® air for £3m school extension
Story

The £3m development of two blocks for sixth-form boarding in Housman Hall at Bromsgrove School will create 49 new en-suite study bedrooms. The first building was completed in October 2013 with the second due to be finished by the end of August. Robothams Architects specified Klober's air-open roofing underlay Permo® air as one of only two membranes approved by the NHBC Standard for use without supporting high level ventilation.
The old central house at Housman Hall, formerly the home of Old Bromsgrovian poet AE Housman, is listed with the site overall in a conservation area. Permo air therefore enables both long span roofs to be unaffected by vents within a roofline which is in the vernacular style. As such, Permo air made a tangible contribution to a development which preserves and enhances the character of Housman Hall by replacing the former boarding wings with a more sympathetic development.

VMZINC provide face of iconic Thameslink viaduct
Story


Jestico and Whiles design becomes London landmark
London Bridge station, the capital's oldest railway terminus, presented a major bottleneck through lack of capacity either to increase train frequency or service longer trains. Three different operating companies use it with six lines continuing to Cannon Street, Charing Cross and Blackfriars. Of 86 trains each hour only one Thameslink train could be accommodated in the face of demand for 18.
A new 400 metre viaduct and 1,080-tonne, 70-metre bridge over Borough High Street was therefore built to address the congestion issue. Described by architects Jestico and Whiles as an iconic structure, its distinctive appearance is provided by 2200m2 of VMZINC curved cassette panel facades in pre-weathered QUARTZ-ZINC®. The material was fabricated by EDM Spanwall and installed by specialist architectural metalwork and faÇade contractor the McGrath Group. The material will retain its appearance for years to come and in doing so requires minimal cleaning and maintenance.
In addition to construction of the viaduct work also included demolition of existing buildings, temporary relocation of Borough Market to adjacent land and removal, refurbishment and reconstruction of the existing cast iron market structure.
