Mitsubishi Electric is using the Ecobuild Show (1-3 March 2011, ExCel, London) to highlight the energy saving potential of advanced heating, cooling, ventilation and power generating equipment, whether for new build or retro-fit.

“We all know the importance of reducing energy consumption and the impact this can have on cutting fuel bills and there is a real potential to tackle the problem of existing buildings using advanced energy saving equipment,” explains Donald Daw, Mitsubishi Electric's Commercial Director.

The company's stand (S2030) will show off the latest developments in domestic and commercial heating, with the Ecodan® range of products that can help achieve renewable energy targets, cut fuel bills and provide reliable, renewable heating for almost any building. Ecodan provides low carbon heating and hot water, with domestic models available in 5kW; 8.5kW and 14kW units and the commercial range starting from 25kW.

Also on the stand will be advanced Photovoltaic (PV) Arrays which can not only lower overall power consumption but can also help generate an income through the Government's Feed In Tariff (FIT) by selling excess energy back to the grid.

Mitsubishi Electric is unique in the world of PV because it manufacturers all of the individual components – the cells, the panels and the inverters – and is also the first manufacturer in the UK to develop a complete PV Pack, designed specifically for residential properties with pitched roofs.

As our homes become more energy efficient and air tight, ensuring appropriate ventilation is increasingly important and the company will be showcasing its DC Lossnay heat recovery ventilation system, which addresses the need to provide energy efficient ventilation to well-insulated modern homes.

One of the major advantages of the Lossnay system is that in summer, when houses have heated up during the day, a special bypass mode can be used to bring in cool fresh air at night, eliminating the need for mechanical cooling.

Mitsubishi Electric has taken a stance against any major growth of air conditioning for the UK's homes because it is unnecessary and unsustainable.

In the commercial sector though, the company is a strident advocate of the increased use of advanced air conditioning to provide energy efficient buildings with a comfortable internal environment. On the stand will be the new City Multi YJM-A outdoor unit which offers some of the highest levels of efficient simultaneous heating and cooling available.

“Legislation is increasingly driving the way we use energy in our buildings and rising fuel prices mean that there has never been a better time to find ways of improving things,” explains Daw. “With this comprehensive range, we are providing energy efficient equipment that can help achieve this.”

Among the many heritage refurbishment projects being undertaken by traditional metal roofing contractors, VMZINC is now providing specialist advice to a growing number of architects. Experience drawn from regular restoration work using zinc throughout Europe has led to the company supplying materials for projects such as St Mary's Church Plas Power and the highly acclaimed Clapham and Sheffield Bandstands.

St Mary's Plas Power is of late 19th century construction and still owned by the Fitzhugh family. As the last remaining privately maintained chapel in Wales to hold regular services, Heritage and CADW funding was obtained to replace the original zinc roof and rainwater system, dating from 1875. Use of pre-weathered zinc not only captured the style of the decades old patina but provided a colour which will continue to age normally.

By contrast, the £1.2m refurbishment of Clapham Common's Grade II listed bandstand involved VMZINC in the manufacture of a bespoke, 62-section natural zinc roof and central finial. Designed by Thomas Blashill, then architect to the London County Council, it was erected in 1890 and is believed to be the largest of its type remaining in the UK. In 1995 it had been placed on English Heritage's 'Greater London Buildings at Risk' but had fallen into serious disrepair. Among factors affecting zinc's specification by architects Dannatt Johnson were its resistance to corrosion, weight and the ability to meet a highly complex roof design. 1:1 roof replication was undertaken, manufacture being divided into sections for cutting and shaping. Plaster prototypes were also used to create drilled sections and to design the punching moulds. A finely crafted curved wooden structure was built to support the zinc covering and the end result is an exceptional illustration of zinc's versatility.

Renovation of the derelict Grade II listed Victorian bandstand in Weston Park Sheffield formed part of a £2.7 million Heritage Lottery funded project to create the city's first municipal park. It is again thought to be the only surviving example of such a design, VMZINC's 0.8 gauge natural zinc having been fitted using sliding caps, one of the earliest techniques for constructing a zinc roof. The material was laid hollow, supported by timber boarding, and wired to the wrought ironwork frame. Archive photographs were used to ensure all original detailing was accurately replicated. Work was carried out to English Heritage Best Practice standards for conservation and restoration, with components being hand crafted.

Zinc has proved to be equally suited to church projects in which a combination of styles was required. There is no better example than the Community Centre Annex to St Pancras RC Church Lewes. The sweeping curves of the pre-weathered, standing seam zinc complement the traditional Victorian style in which clay plain tiles and brick have been used.

The new £3 million Bramall Learning Centre at RHS Garden Harlow Carr stands out as a resplendent two-storey structure, surrounded by beautiful landscaped gardens. The Centre has exemplary environmental credentials and as part of the theme of environmental sustainability, Timbmet was commissioned by joinery contractor, Dalton Joinery to source and supply FSC European Oak worktops for the interior of the new Blundell Library, which forms part of the construction. The specification called for timber that complemented the other sustainable materials used in the build process. FSC European Oak is a solid wood that does not deteriorate with age, rather it matures and improves to give a richer, deeper colour. Being solid, any surface damage in future to the worktops can be repaired simply and quickly.

Since it was opened in Summer 2010, the Centre has achieved its design aim to be amongst the most sustainable buildings in the country, achieving an excellent carbon zero BREEAM rating, proving its green credentials. According to David Dalton of the the consistent dedication to its responsible business commitment to pursue the principles of sustainable development in its operations. “Dealing with Timbmet is always easy due to their professionalism, knowledge and helpfulness,” he commented. “The Timbmet business manager sourced the exact products we required for this high profile and very meticulous project.”

The result is a visually stunning interior, with the worktops complementing the quality of the rest of the building, the entire fabric of which has been constructed primarily from natural and unprocessed materials. Head of RHS Garden Harlow Carr, Liz Thwaites is understandably proud of the sustainable achievement, commenting: “We are absolutely thrilled with the opening of the Bramell Learning Centre in Harlow's 60th year. Its creation is a tremendous achievement for all those involved.”

Grant Shapps MP for Hatfield and Welwyn and Housing Minister for the Coalition Government, has opened a new Renewable Energy Centre at Mitsubishi Electric’s offices in Travellers Lane, Hatfield.

The company is a leader in the manufacture of residential air source heat pump heating and photovoltaic power generating systems which can reduce a home’s heating and energy bills and the local MP was invited in to officially launch the centre on Friday 10th December.

“At the moment, there are few homes in the Hatfield and Welwyn area that are benefiting from the lower fuel bills that these systems can offer,” explained Martin Fahey, Mitsubishi Electric’s Green Gateway Manager. “As a major employer in the area, we wanted to show our MP how simple and reliable the technology is, and how homeowners, housing associations and landlords can have the confidence to make the switch from gas and oil.”

Mr Shapps was shown around the new centre, which will be used to train thousands of plumbing, heating and electrical engineers over the coming year.

Mitsubishi Electric’s Green Gateway Manager, Martin Fahey explained to the MP how the company is ensuring the highest standards of training to provide reliable power generation and home heating. These high standards are also carried through to the company’s commercial heating and air conditioning products.

The MP immediately issued a report on his visit on twitter, the contents of which can be accessed at http://twitter.com/grantshapps . He has also included a photo of his visit available at http://twitpic.com/3emznw .

Mitsubishi Electric is fully committed to the Government’s Microgeneration Certification Scheme (MCS) which sets out the high standards of installation and maintenance required for renewable technology. Mitsubishi Electric’s Ecodan air source heat pump and its range of Photovoltaic (PV) power generating equipment is both MCS accredited.

Electrical industry folklore has it that lighting controls are complicated and suitable only for large projects. Not so. Thorn has introduced SensaModular, a simple ‘plug-and-play’ dimming solution for single room applications that is capable of taking in and responding to sensors and other interfaces, without the need for extra commissioning tools.

Central to the system is the SensaModular controller which processes the inputs from the sensors, photocells, scene plates, switches and hand held IR devices to operate up to three groups of luminaires, thus creating ideal conditions for daylight-linking, presence-linking and scene setting. The device can automatically detect and operate DSI or DALI ballasts, or any combination thereof (up to 50 DSI or 25 DALI ballasts per group), and two screwdriver adjustable rotary switches set the operation mode (‘On/Off’, ‘only Off’ or ‘On/Corridor’) and off delay time for the presence-link function. This makes commissioning quick, easy and safe. The controller comes in two sizes: for two or three luminaire groups.

Compared with traditional dimmer pack or building-wide solutions, SensaModular is easy to install via polarity-free 2-wire connections, using standard mains rated installation material.

The new range will open up completely new markets for dimming applications, particularly in offices, schools, leisure buildings and warehouses. Stefan Hauer, manager of Thorn’s indoor controls, explains: “With the latest advances in electronics it is now possible to offer controls for single rooms which can be remarkably cost effective and which will appeal to people who may never have thought of using lighting controls.

“Considerable interest is likely to be aroused for a wide variety of applications, driven by the ability to select from three methods of daylight-linking. For example, a large, zoned office is a place where two or three ‘look down’ multi-sensors, one for each luminaire group, can be quite useful. Alternatively, for smaller offices one ‘look down’ multi-sensor can be used for all groups. For applications with rows of fittings and/or high ceilings – such as sports halls and factories – simplicity of daylight control can be provided by one ‘look out’ photocell.”

Thorn has developed a high-lumen output LED version of its already successful Cruz downlight. It uses active cooling technology to outperform compact fluorescent (CFL) in terms of energy efficiency and quality of light from a third smaller aperture.

Cruz LED delivers 2,000 lumens, with only 6% optical losses in either warm white (3000K, 51 lm/W) or cool white (4000K, 55 lm/W), equating to 2 x 26W CFL downlights.

The downlight is DALI dimmable and delivers 100% instant light with a rated life of 50,000 hours (70% lumen maintenance), which is five times that of a CFL.

System filters have been much in evidence for the past few years as a means of offering a 'belt and braces' type response to debris circulating in a heating system. Whilst chemical water treatment will address the bulk of the debris in a system, even after careful use of a cleaner and an inhibitor, some debris will still be circulating in the system. To ensure that this doesn't cause grief, its best to get the debris out and this can be done quite simply through the use of a system filter.

The system filters available vary massively both in technology and materials – and to be fair, in the results they achieve and the reliability with which they operate. Some system filters remove just magnetic debris. Others claim to remove magnetic and non-magnetic debris. Some are manufactured from plastic others from brass. Choosing the right filter that will last as long as the system, is a key consideration when making that choice.

Sentinel has for some time been successfully selling its System Filter, providing a solid, reliable and cost effective solution to the need to shift all types of system debris from domestic heating systems. Its popularity with housing associations and local authorities who traditionally test their purchases pretty hard, suggests that it's a reliable and cost effective solution to removing muck and 'gunge' from systems.

The Sentinel System Filter, is a compact, robust, fully sealed brass unit, that's quick and easy to fit and will last the lifetime of the system, helping to eliminate those unwanted call backs, saving you time and your customer money. The unit removes all debris, not just magnetic debris, protecting the boiler and maintaining design efficiencies. With no moving parts, it will not clog and is very easy to clean and maintain, with no magnets to remove, no need to dismantle and no valves to shut off.

The Sentinel system filter has been designed to work alongside Sentinel X800 Jetflo cleaner. X800 is a powerful, highly active cleaning agent. Its unique composition allows it to act as a penetrating dispersant under neutral pH conditions. The formula also importantly contains agents to protect metal from corrosion. Sentinel products comply with the BS7593 Code of Practice for correct water treatment in domestic systems, which states that “Filters which collect magnetite may be beneficial as part of the flushing procedure. These should be used with a chemical cleanser to mobilise the magnetite and aid its transport to the filter”.

So ideally, installers need to cleanse the system with Sentinel X800 Jetflo, then fit a Sentinel System Filter. X800 and the Sentinel System filter have been specifically designed to work together in mobilising magnetite and other forms of heating system debris, to enable its removal from the system, thereby restoring system efficiency.

There have been a number of reports in recent months emanating from social housing providers in particular, suggesting that a number of boiler heat exchangers have become blocked due to dirt particles building up between the heat exchanger plates

Two London & Quadrant Housing Association owned properties and ten owned by Enfield Homes were identified to carry out 'system cleans' using Sentinel X800 Jetflo cleaner followed by treatment with Sentinel X100 inhibitor/protector. After the clean had been undertaken in each case, Sentinel System Filters were fitted in all properties to the heating systems on the return to the boiler, to provide long term protection from, and removal of, any circulating debris – magnetic or non-magnetic, left in the system.

Between four and six weeks later, samples were taken from each of the properties, where access could be gained, from both the system water and the 'blow down' from the installed Sentinel System Filter.

Analyses of the samples are presented below:

These results clearly show the benefits of fitting a Sentinel System Filter. Although the systems were cleaned, flushed and inhibited, there still remains the potential of some level of suspended solids still remaining in the heating system.

The use of a Sentinel System Filter removes this debris effectively and will continue to remove it for as long as it is in place, resulting in a very low level of suspended solids in the re-circulating water.

So it is clear that fitting a Sentinel System Filter as part of the water treatment regime offers the permanent, on-going level of protection required by social housing providers in the heating systems in the homes they own and manage. Having the Sentinel system filter in place eliminates unwanted call backs to contractors or a providers own direct workforce, to remedy problems associated with debris in circulating water in a domestic heating system.

The Sentinel system filter is clearly a solid, reliable and cost effective response to magnetic and non-magnetic debris in a heating system. And it doesn't leak and it certainly doesn't split!
