“

e shape our buildings; thereafter they shape us” – these great words of Sir Winston Churchill form a profound architectural truth that applies to both public and private buildings. For Birmingham’s new library this statement could not be more literal. Since its initial go-ahead in 2007, the design plans have been heavily influenced by the city’s cultural and industrial heritage. Now with the building officially open, the stunning new knowledge hub will inspire, educate and entertain thousands of visitors from around the country.

Named The People’s Palace by lead architect Francine Houben, the new Library of Birmingham is a project of outstanding execution. The 10-storey building is wrapped with a futuristic film of geometric cladding, drawing visitors to Centenary Square on which it sits.

As well as housing literary treasures such as one of the world’s greatest Shakespeare Collections, this new centerpiece comprises an adult and children’s library, study centre, music library, community health centre, offices, exhibition halls, café and lounge space and roof terraces. For more information on how this striking resource will shape Birmingham’s city, turn to page 28.

Elsewhere in this edition, we profile a striking array of projects from a sustainable woodland kitchen through to a well-respected arts venue that is aspiring to be the first carbon neutral theatre in the world. In industry news, Hilson Moran’s Sustainability Director Chris Birch reflects on the latest revisions to Part L of the Building Regulations and asks the question “was it worth waiting for?”

Meanwhile, in this month’s Voice of the Industry Contour Casings explores how, as an industry, we can overcome one of the significant hurdles in BIM implementation – BIM components.

a nourishing lunch but a warm shelter from the weather during winter.”

The new eco building, designed in a ‘snail shell’ framework, enables the college to serve lunches for up to 100 students and staff working on the farm and woodlands and provide training opportunities for young people with learning difficulties and disabilities.

A build for self-discovery

The new woodland kitchen and classroom for students and visitors of the Ruskin Mill College, Gloucestershire was officially opened in June 2013. With an eco-friendly design and technologies, the kitchen was planned to enable students to have cooking lessons, host events and be taught all within an inspiring and unique building structure which complements its natural surroundings.

T

he Ruskin Mill kitchen has been built on the site of the previous sheltered kitchen which was set up where the farm meets the woodland edge, isolated and calm, out of sight of roads and houses, which provided lunches for students and staff working on the farm and woodlands. This tented structure housed a kitchen sufficient for students and tutors to prepare lunch as part of the educational course using food grown on site. After over 10 years’

use, this field kitchen was outgrown, and architects, David Austin & Associates, were commissioned to design a new woodland kitchen building with increased capacity and high quality kitchen facilities.

Janine Christley, Director of Fundraising for the College explained: “The college is located on a 120 acre campus with much of the educational curriculum based in the landscape, through the farm, fish farm, woodlands and market gardens. The kitchen is a vital facility to provide not only

In addition to the communal function and design of the kitchen, sustainable and renewable technologies were embraced.

The timber structure creates a sustainable foundation to which a turf roof was added to benefit from natural insulation.

Matthew Austin, Architect at David Austin & Associates commented: “The building’s nautilus plan form arises from the client’s desire to embody the spirit of selfexploration, discovery and transformation through its built form. The central douglas fir structure, with a rising exposed ridge beam, follows the spiral plan form. A series of tree-like posts, jointed with galvanized steel connector plates, cruciform at the base and springing diagonal braces at eaves level, support the ridge beam and set a rhythm within the space.

“The palate of materials is tied between rough structure and refined finishing through the use of douglas fir for fine joinery elements including windows, sills, skirtings and dado. Birch ply completes the palate of timbers, lining the internal walls to dado height, facing the internal doors, and forming fitted furniture,” adds Matthew Austin.

The task to assemble the rough sawn structure and refined finishes fell to Principal Contractor JR Building. John Ramsden, Director explained that the

The turf roof means rainwater can be harvested, the surrounding habitat can be enhanced and complemented while the shelter will have added natural insulation in winter.

Low impacting technologies were incorporated into the design with a grey water system, compost toilet, energy efficient heating and rainwater harvesting.

challenge to build a snail shaped timber frame structure in the woods was a pleasure to undertake, making full use of adapdability and flexibility to produce the architect’s design using a combination of traditional and modern timber construction methods. The end use and benefits of the building makes the project all the more special.

The timber frame construction uses native species for many of its elements, with nearly all construction carried out by the JR Building’s own highly skilled team.

The roof uses earth excavated from the site, and is planted to match flora found on site using locally sourced seed.

Ruskin Mill College is an independent specialist further education college and part of the Ruskin Mill Trust. It provides residential education for 16-25 year olds from all over the UK with severe learning difficulties, including autism, Asperger’s Syndrome and developmental delay. In 1994 Ruskin Mill Trust expanded their land based training facility bringing in livestock, expanding their market gardening programme from the Ruskin Mill valley to an agricultural scale, and developing their woodworking and woodland management courses.

David Austin & Associates Ltd were retained architects for Ruskin Mill Trust for many years from 1990, and have continued their work with the college for 23 years as the campus has grown in Gloucestershire as well as sister colleges being established in Stourbridge and Sheffield. Works through Ruskin Mill, Horsley Mill and Fishery, and Gables Farm have established an architectural unity throughout the college’s estate which responds to the needs, aspirations and values of the organisation whilst both drawing on and developing a spirit of place.

Sustainability in Development

Groundbreaking investment The stunning new development designed to underscore Robert Gordon University’s ambition to raise its global profile is remarkable in many ways, not least the low carbon footprint of the central campus building. of cooling should be provided.

Consequently the amount of CO2 produced is far lower than for conventional heating and cooling, creating the potential for considerable carbon savings – a prime attraction for the university which, in common with other universities, has to meet tough statutory obligations to reduce its carbon footprint.

These figures are not pie-in-the-sky: GI Energy’s installation at the iconic One New Change complex in the shadow of St Paul’s Cathedral in London has in practice produced a Co-Efficient of Performance for heating and cooling of 4.1 over a full year of operation. Performance data was collected over an entire year by GI Energy’s sophisticated monitoring and

he stylish new main campus building which has a superb setting on the banks of the River Dee houses the largest commercial Ground Source Energy System (GSES) in Scotland, recently commissioned

by GI Energy.

By drawing on the heat stored naturally underground – and returning excess heat from the building to the ground – the GSES provides a truly renewable form of heating and cooling that dramatically cuts the building’s carbon footprint.

Its performance is expected to outstrip conventional forms of heating and air conditioning: for every kilowatt of power required to run the system, up to five kilowatts of heating and up to six kilowatts

Sustainability in Development control unit.

Similarly the company’s GSES system at Oxford University’s new Oxford Earth Sciences building, where the constraints of the site required there to be back-up heating and cooling from gas boilers and electric chillers, operated so effectively that it produced carbon savings 23% higher than originally anticipated, despite the building requiring more heating and cooling than expected when it was at the design stage on the drawing board.

Ground Source Energy Systems work by exploiting the fact that heat from the sun is stored in the earth. They consist of an array of underground pipes linked to a series of heat pumps. Liquid pumped through the pipes extracts heat from the surrounding ground. It is then passed through the heat pump which brings it up to a temperature high enough for central heating. For cooling, the system is simply used in reverse. GSES

systems are especially efficient when both heating and cooling is required, as heat is cycled between the ground and the building then back again.

The pipes – commonly known as earth loops – can be arrayed horizontally a few metres below the surface or sunk in deep boreholes. They can also be submerged in lakes or reservoirs or (low pressure) underground aquifers. A technique developed by GI Energy and Cementation Skanska also allows them to be incorporated within the foundation piles of a building.

Great expectations Robert Gordon University in Aberdeen – voted Best Modern University in the UK 2012 – is moving all of its teaching to its Garthdee campus which aspires to become the best riverside campus in Europe.

The extensive grounds were generously donated in the 1950s by Scottish architect Scott Sutherland during his lifetime. He handed over the house in which he had lived for many years and helped to fund its extension in order for it to accommodate the School of Architecture of the then Robert Gordon’s College where he himself had studied. The Scott Sutherland School of Architecture and the Built Environment has been based in the house for more than half a century.

The £115 million redevelopment of the Garthdee Campus has been designed

by BDP architects and the centerpiece of the 120-acre site is a new building for the School of Art and Architecture which is arranged as two shallow plan linear teaching blocks grouped around an internal street and courtyard space.

Sustainability in Development The new campus building at Robert Gordon University in Aberdeen did not present the same level of challenge as One New Change, where critical parts of the GSES system had to be incorporated into foundation piles, or Oxford Earth Sciences, where the size of the system was limited by the size of the site and the fact that pipes could not be sunk beyond 64 metres underground lest they hit a high-pressure underground aquifer that ran underneath the building. There was a very real danger of flooding parts of Oxford!

Solid foundations With Aberdeen being known as the “granite city” unsurprisingly the ground underneath the site was solid granite rock which, although hard to drill through and abrasive, had other advantages.

John Mackintosh, Engineering Manager, of GI Energy, said: “Granite has really good thermal conductivity. It’s very dense, so is ideal for geothermal systems. Despite it being a hard and difficult rock to drill, it’s all very consistent, so we know what to expect and get good, stable results.

“From the modeling we are expecting a Co-efficient of Performance of up to 5 for heating and up to 6 for cooling.”

All of the building’s cooling and its base heating load are provided by GI Energy’s GSES system, which can provide 900 kilowatts of heating and 900 kilowatts of cooling. Back up heating is supplied by conventional gas boilers.

The new building is arranged as two shallow plan linear teaching blocks grouped around an internal street and courtyard space

The ground underneath the site was solid granite rock which, although hard to drill through and abrasive, had other advantages

GI Energy, which as one of the market leaders and pioneers of the use of Ground Source Heat Pump systems in the UK, has built up considerable expertise in drilling, sunk 66 boreholes to a depth of 200 metres to accommodate the earth loops.

These were buried underneath the three car parks created adjacent to the main campus building.

There are eight heat pumps – all reversible – and the performance of the whole system is controlled and remotely monitored by GI Energy’s bespoke computerised control system in order to optimise its performance. Sensors throughout the system take readings and the control system can switch each pump individually between heating and cooling mode, depending upon factors such as the external and internal air and ground temperatures.

Chris Davidson, Director of Development at GI Energy, is expecting the GSES at the BREEAM excellent rated

Garthdee main campus building to provide “exceptional” Co-efficients of Performance.

He explained: “The local granite rock acts as an inter-seasonal energy store, absorbing the summer heat that is rejected from the building and storing it for re-use in the winter period when heating is required.

“Ground Source Energy Systems have an enormous role to play in reducing carbon emissions and providing energy efficient heating and cooling.

“They have become even more attractive since the Government nearly tripled the level of Renewable Heat Incentive payments for large GSHP heating systems and should provide considerable savings on running costs in the long run.

“The question for developers now is – why would you not want to benefit from a Ground Source Energy System?”

Voice of the Industry

Standard practice

The quality of data is key to being able to form comprehensive and accurate specification

Driven by the Government’s BIM agenda to make ‘Level 2 BIM’ mandatory on government contracts by 2016, BIM is being championed as the vehicle to a more sustainable industry and its processes. Here, Contour Casings outlines the importance of quality data. a powerful tool.

As the primary advantage of designing using BIM is enhanced co-ordination and the ability to extract comprehensive information at various stages of the design and asset management process, the ability to easily locate, download and import manufacturer-specific BIM objects containing rich embedded data will be fundamental going forward. The latest BIM content is now loaded with exhaustive background data, allowing pre-emptive decisions to be made throughout the full life-cycle of a building.

Steven Attwood from Sprunt Architects, comments: “The quality of data is key to being able to form comprehensive and accurate specifications. By sourcing good

quality BIM families from progressive BIMready suppliers, we know that all technical information is up to date, removing the potential for error. All consultants working together on the project also need to be BIM-ready; essentially the project needs to be fully-BIM or not BIM at all.”

Although rapidly gathering pace, the adoption of BIM in the industry is still at a relatively early stage, with standards and protocols regarding data still being formalised.

At the beginning of its 5-year program, the UK Government’s requirement for the first year was that every project should have a “spreadsheet containing as much information about a building in as complete and as useful form as

O

ne quote that echoes through the annals of time is “knowledge is power” – this is the essence of BIM (Building Information Modelling).

With the uptake of BIM now gathering significant pace in the industry, designers, contractors, facility managers and manufacturers are now benefitting from the time and cost savings, clash detection, estimation and scheduling efficiencies and enhanced collaboration that BIM can deliver.

However, it has been concluded from numerous industry reports that a distinct lack of high-quality BIM components was one barrier slowing the rate of adoption in the industry, with those that are available, not containing sufficient background data to allow the full potential of BIM to be levied.

High-quality, powerful BIM objects consist of three essential attributes, visual representation, embedded data and modelling capability.

Embedded data A visual representation allows key dimensions to be gathered, the latest BIM content is now also created with dynamic rendering, which can map an array of vibrant pre-loaded finishes across the surface of the object. As well as being a useful visualisation tool permitting designers to take a client on a virtual tour of the building, the selection of finishes can now be done at design stage, reducing construction time and removing any opportunity for human error.

However at a later design stage deeper levels of information are required, this is where the embedded non-graphical data becomes the focus. It is the connection between the visual representation and the rich background data that makes BIM such

Voice of the Industry interrupt the design process to create an object themselves, or spend time locating objects in paper-based catalogues.

Early-adopters amongst building product manufacturers are now providing highquality BIM components that can be downloaded fast and for free from BIM Libraries located on supplier websites.

Some of these websites are now increasingly being used as complete BIM toolkits for architects and consultants to deliver their BIM projects, containing extensive technical literature and case study information and catering for both experienced BIM designers and those who have recently invested in software and training.

“Being able to download an object and import it directly into a BIM saves designers considerable time,” says Steven Attwood from Sprunt Architects. “Having access to websites and objects that have extensive up-to-date information allows the architect to instantly know what is available. Previously we would have to draw the object ourselves, only to discover that it is not achievable and then having to find some middle-ground with the contractor and client. This allows specification at a much earlier stage in the design process.”

The most innovative objects from building product manufacturers embracing BIM has been built parametrically to allow flexible modelling techniques. Parametric objects allow the user to ‘stretch’ an object into a range of sizes and shapes, but with inbuilt constraints that prevents manipulation of an object into a form that cannot be manufactured. The highest-quality BIM content is built with maximum design flexibility for the user in mind, containing a multitude of user-controlled design options.

“This is a much better way to work,” says Steven Attwood from Sprunt Architects. “It allows the designer to maintain design control, flexibility and freedom. When we alter the size of an object, all the project information is also updated, making scheduling and estimation a far more efficient process and removing any margin for human error.”

The effective creation and availability of powerful, data-rich BIM objects that combine all essential visual, data and modelling attributes, is fundamental to the rate at which BIM becomes a standard industry practise. It is also key to the full power of BIM being levied, benefitting designer, asset manager and end user.

possible”. This spreadsheet is known as COBie – Construction Operations Building Information Exchange.

COBie helps organise information about new and existing facilities and document both Buildings and Infrastructure assets. It is a means of sharing structured information taken from multiple platforms and software, just like CDM and BIM. All high-quality and powerful BIM components will be compatible with the COBie 2012 specification and will contain links through to where information such as manufacturers O&M instructions can be obtained; typically this is downloaded from the manufacturers’ website.

Proactive building product manufacturers now regularly consult with designers to understand precisely what technical information they require and in what file formats.

Current industry feedback is that although the demand for BIM objects is rapidly growing, during the transition period until BIM becomes standard practise designers will still require traditional CAD documents containing full specification information.

Responding to this, forward-thinking manufacturers are now launching innovative websites where BIM objects

Partition Walls

O

Variflex panels can be separated from the frame, allowing individual units to be replaced if damage should occur

New revenue stream for hotel

■

A modern partitioning system will certainly deliver more flexible space but, if designed with careful consideration it can also generate a new revenue stream for a business, potentially paying for the initial capital investment and increasing profits into the future.

ne such example is the Radisson Park Inn Hotel in Peterborough, where the three stud-wall divided meeting rooms just did not allow them to maximise profits from hiring income.

Working in close partnership with contractor Heritage London and architect Jefferson Sheard, partitioning experts Style aimed to deliver a moveable wall system that would extend the use of the current facilities. “We recommended dividing the spacious functions area with DORMA Variflex sliding panels, creating three large meetings rooms and break-out area that all benefit from an abundance of natural light,” explains Mike Fine, Style’s Director for the Midlands.

“Since Style’s moveable walls were installed nine months ago, we have significantly increased the hiring revenue,” confirms Simon Smith, General Manager at the hotel. “The system is very flexible and allows us to quickly divide the rooms into private areas to meet the requirements of a wide variety of groups.”

Further extending the functionality of the space to the evenings and weekends, the area can now be opened out to create an attractive venue for weddings and social events allowing the hotel to compete in a highly lucrative sector that was previously unobtainable.

Apart from being easy to manoeuvre, DORMA Variflex delivers exceptional privacy to divided areas with sound reduction of up to Rw 60 dB and also has a 30 minute fire rating if required. A long term solution, the Variflex panels can be separated from the frame, allowing individual units to be replaced if damage should occur.

The Radisson Park Inn Hotel currently has the panels finished in a very clean, pearl grey laminate, and when closed each has a pass door with a contrasting wood veneer American oak finish. When the interior decor needs updating however, it is a simple matter of changing the panel finishes without having to replace the whole wall structure.

“Variflex provides a wide choice of elements and stacking/parking arrangements,” explains Mike Fine, Style’s Director for the Midlands. “The system’s particularly high level of flexibility makes it ideal for many scenarios, even in the case of complicated room proportions where sloping ceilings or circular spaces have to be accommodated.”

Drainage

Gas plant specifies robust drainage system Located on the edge of the British continental shelf some 125km north-west of the Shetland Islands, lie the Laggan and Tormore gas and liquid hydrocarbon (Petroleum) fields, surely a uniquely challenging environment, but one with great potential for the UK energy industry.

Offshore Engineering & Operations unit in October 2010. Morrison Construction was then awarded a contract by Petrofac in June 2011 to carry out site infrastructure works including underground and surface water drainage facilities, roadways and buildings.

With the shoreline and waters around Sullom Voe home to large populations of seals, dolphins and other sensitive wildlife habitats – there are a number of off-shore Special Areas of Conservation (SAC) in the area, Morrison Construction and other contractors were asked to ensure any ecological impact was minimised during and after the construction phases.

The Shetland Gas Plant site is situated on a steep slope and required extensive earthworks.This together with the plant’s location and harsh weather conditions characterised by 1000 to 1700mm annual average rainfall and frequent storm events, meant the surface water drainage system employed would have to be robust and very efficient at controlling surface water runoff.

All collected surface water had to be

Calculating the hydraulic performance needed, Morrison Construction was looking for a channel system available in at least three sizes to drain the site’s roads and service areas. After dialogue with Hauraton UK Technical Support staff, the company’s FASERFIX SUPER 300, 400 and 500 channels were specified with Class D400 ductile iron slotted gratings.

The grating specification chosen featured parallel rows of 20mm wide slots, each half metre grating being secured to the channel with the company’s patented SIDE-LOCK system and eight high tensile bolts.The order for the 1425 metres of channel required was placed with Builders Merchants Grafton Group contracts office in Glasgow, who decided to process the orders through their Buildbase Shetland Depot in Lerwick.

Started in early 2010, the Shetland Gas Plant will be connected to the LagganTormore off-shore subsea production system which is being jointly developed by Total E&P UK and Dong E&P (UK). Once operational, the Gas Plant will be capable of processing up to 500 million standard cubic feet of gas per day and will employ around 70 people. Planned to be on stream by mid 2014, the new facility will be operated by Total.

An initial contract was awarded to Irish company, Roadbridge in March 2010 to carry out the site preparation works and the construction of a 2.4 mile access road.

Building protection Architects and engineers should consider a wide range of factors when specifying louvre systems. This will ensure the maximum benefits are gained from this effective ‘fabric first’ solution to improving a building’s sustainability, says Simon Hunter, Product Manager of Louvres at Construction Specialties.

A

n estimated 45% of the UK’s carbon dioxide emissions come from buildings: principally from space heating and cooling, water heating, lighting and other building systems.

As a result, public and private sector clients are seeking ever-higher sustainability ratings for their buildings. The emphasis is on ‘fabric first’ solutions, which means designers are increasingly using natural light and ventilation as well as higher levels of insulation, combined with more energyefficient building systems.

Louvre systems have an important part to play in improving energy performance.

Needed on most buildings, these systems allow air flow, both intake and exhaust, to HVAC and other building systems, while protecting these openings against rain ingress.

As well as allowing natural ventilation, an efficient louvre system can improve air flow, which means less power is needed to move the volumes of air required. In the case of HVAC systems, this energy efficiency improvement can sometimes mean a smaller and less powerful system is required for space heating and cooling.

There are three main types of louvres: screening louvres, standard drainable louvres

22

and storm-resistant (or performance) louvres.

Screening louvres have the simplest designs and are suitable for locations where water penetration will not cause significant problems and economy is the primary consideration, such as screening of rooftop plant or in a multi-storey car park. They have simple blade shapes, which allow good air flow but give limited defence against rain.

Optimum defence Standard drainable blades give good air flow and some rain defence but do not perform so well with wind-driven rain.They are used when occasional ingress is not a major concern and where some drainage of cascading water is required.

Storm-resistant, or performance, louvres on the other hand, typically provide moderate to good air flow with excellent defence against wind-driven rain.They are used when high levels of ventilation and maximum protection from the rain is needed, for instance when sensitive equipment such as HVAC plant is behind the louvre.They have blades with complex profiles and use the “tangential separation effect” to force air entering the louvre to

change direction rapidly and shed water droplets, which then drain away.

To get the best possible results from a louvre system, it is crucial that it is specified correctly. Specification is always a compromise between air flow and water ingress.Traditionally, louvres are specified based on free area (typically 50%), calculated by measuring the clear distance between the blades and multiplying it by the width of the louvre panel (or height, if the blades are arranged vertically).

Clearly, free area is dictated by the size of the louvre. Industry commonly uses a 1m by 1m louvre when quoting free area but, in reality, louvres are never precisely this size.

In fact, the smaller the louvre, the lower the proportion of free area, as it is affected by the space taken up by the head, cill, jambs or mullions. Free area is also affected by other factors, such as additional structural support, or if bird screens or insect meshes are fitted.

Finally, and perhaps most importantly, free area alone does not take into account how the air flows through a louvre. All louvres restrict the passage of air and this resistance is called the pressure drop.This dictates how much air gets through the louvre and therefore how much can effectively be used.

Roofing, Cladding & Insulation

Memorial Hospital, Colorado Springs

Too high a pressure drop and not enough air will be allowed through, which can cause a rapid temperature rise inside a building, in turn causing problems with plant.

As louvre design has changed in response to demand for better water protection, with a resultant change in performance characteristics, engineers and architects should move away from specifying louvres purely on free area and instead consider a number of different factors.These include

site location, prevailing weather conditions (in particular wind direction) and the location and exposure of the louvres (which will dictate air flow rate and the amount of potential wind-driven rain).

These should then be balanced with the required air flow, the maximum acceptable pressure drop, the degree and depth of acceptable water penetration and finally, the building’s exterior design, which can dictate where louvres can be placed and how they fit into the aesthetics.

Louvres come in a wide range of designs to suit any application.Those with visible mullions (the structural members that support the blades) can be used as a design feature, in line with curtain wall panels or windows.Visible mullions are not only aesthetically pleasing, they are designed to be part of the drainage system.

A system with hidden mullions, on the other hand, gives clean, architectural lines because the support system is behind the blades.These systems are normally used to provide screening and protect buildings with multiple openings.

Most performance louvres can be shaped on plan to give curves or the impression of a curve (by using faceted panels). It is important to realise, however, that performance can be reduced, particularly if horizontal louvres are being used on circular shapes, as the drainage characteristics of

their complex blade profiles can be affected.

Louvres are also available with different finishes and colours but some finishes are more environmentally-friendly than others.

All Construction Specialties louvres, for example, can be specified with either an anodised, polyester powder coat, or with a non-toxic,VOC-free powder coat, which is more durable than the standard architectural metal finish of liquid fluoropolymers (the manufacture of which produces VOCs and hazardous waste).

A well-designed louvre can enhance a building’s design and will reduce the pressure drop, allowing a larger volume of air through and thus cutting the amount of fan power needed to deliver the required air flow.

Conversely, poor specification can lead to rainwater ingress, not enough ventilation, wasted energy and poor performance, not only of the equipment being ventilated but that of the building as a whole.

Louvres are clearly an excellent way of helping architects and engineers meet evermore demanding environmental legislation and client requirements for sustainable buildings. Careful design and specification of louvre systems, balancing ventilation, rain protection and aesthetics, can help improve efficiency, lower energy consumption and reduce carbon emissions.

Legal & Business

Adapting to change Chris Birch, Director of Sustainability at Hilson Moran takes an in depth look at the revisions to Part L of the Building Regulations and highlights why the industry must embark on a steep learning curve if targets are to be achieved.

C

entral to successive Governments’ greening of the built environment is Part L of the Building Regulations. Some details of the latest revision, the much anticipated and very late “Part L 2013”, is now in the hands of the construction industry, but was it worth waiting for?

There is no doubt that the carbon emissions targets are a step forward, albeit a small step. In a nutshell, new homes will need to target a 6% cut in carbon emissions over 2010 levels – a smaller decrease in emissions than was consulted upon. The target for non domestic buildings is 9% below the current regulations. According to the DCLG, the new regulations will save 6.4 million tonnes of CO2 out of the estimated 246 million tonnes that are emitted by UK buildings per year (that’s 2.6%).

These cuts go some way to achieving Zero Carbon buildings, but not far enough.

Coupled with the delays, the industry is left with a very steep climb to meet the deadline of 2016 for homes and 2019 for non-domestic buildings.

In the coming months ahead of implementation in April 2014, the suppliers to the construction industry; manufacturers, software developers, architects and engineers will join the three yearly push towards developing viable technical

24

solutions to meet the new standards prior to the next revision in 2016. But this doesn’t mean that we’re actually going to meet them anytime soon. Inevitably, due to recent economic conditions, many developments which have stalled in construction will be able to continue under the old regulations, which means that buildings designed to the old standards will

emerge for some time yet.

Furthermore, the design software needed to meet the new regulations is not available at present and, when it is, will no doubt go through the usual teething period while problems are ironed out. On this basis, it could be 2015 before any new Part L schemes are on site.

Looking at the detail, we welcome the full implementation of Fabric Efficiency Factors for homes promoting a more sustainable fabric first design approach and hopefully discouraging the tendency to over specify renewables as a quick but costly fix. At the same time however, we are disappointed with the lack of ambition in the new regulations particularly in relation to the lack of new standards for refurbishments and existing homes, which represent the vast majority of UK emissions.

Cost is another issue. According to the DGLC, for the latest changes to Part L, the small increase in construction costs will be heavily outweighed by subsequent energy savings, suggesting a £384m net saving for people and businesses over the average lifetime thanks to the new features. However, the cost is borne by the developers and contractors, and the saving by the home owners and tenants – and there is still very little evidence that home owners and tenants are willing to pay significantly more for sustainable buildings.

In design terms, for major development, the deadlines for zero carbon buildings are just around the corner and further delays or dilutions to the targets, such as those experienced with the Carbon Reduction Commitment, Display Energy Certificates, Feed in Tariffs and the Green Deal, to name just a few, will only hinder the industry further. The coalition seems to be developing a reputation for making bold pronouncements about green growth, only to water down its ambitions when it comes to the nitty gritty of actual policy-making.

But as we creep out of recession, the construction industry is craving certainty to make long term investment plans and isn’t shying away from strong targets.

These revisions to Part L may make for the “Greenest Building Regulations ever” issued by the “Greenest Government ever”, but it’s all about degrees. Let us remember that the UK construction industry is one of the best in the world and has an excellent track record in adapting to new standards and innovative construction methods – but it needs the certainty of a government that is willing to be both bold in its ambitions and reliable and consistent in its execution.

Water Management Roca’s W+W utilises waste water from the basin to fill the cistern

Sustainability takes centre stage Public buildings provide the ideal platform to communicate the importance of sustainability to the people that use their services. The Arcola Theatre, in Hackney, has taken this responsibility very seriously, with the aim of becoming the first carbon neutral theatre in the world and a remit to get the ‘green’ message across to its patrons and local residents.

O

ne of the key elements of Arcola’s sustainability strategy is water saving, helped along the way by Roca’s innovative

W+W toilet; a unit that combines the wash basin and water closet in one, with water from the sink used to flush the toilet.

The Arcola Theatre is one of the most

Water usage cut by half Roca’s W+W utilises waste water from the basin to fill the cistern, saving up to 25% more water in a typical household compared with dual-flush systems. Arcola has been monitoring water usage since 2010 and, following W+W’s installation, the savings have been dramatic – spring 2013’s figures are 50% lower than the previous year.

Making W+W work even harder is the Singles-Pro basin mixer, which features Roca’s innovative Cold Start system, designed to help save both water and energy. The progressive cartridge means the tap turns on with cold water first, drawing on the hot supply only as and when it’s required.

Ruth Mulandi, Arcola’s Commercial Manager, commented: “When we researched water-efficient toilets, Roca’s offering just made good sense. We loved the design of their products and now they’re in situ, visitors find them so intuitive to use.”

In addition to saving water, W+W saves space, with the wash basin housed on top of the cistern. Its modern, L shaped design, fits snugly into the restricted area of Arcola’s toilet cubicle.

Arcola Theatre stands as an example of how an arts venue can do more than just entertain, promoting a greener way to live to its audiences and the wider community.

Roca’s part in this project demonstrates the company’s own remit to make sure our most relied upon conveniences are innovative, functional and above all, sustainable.

respected arts venues in the UK, with a commitment to cutting carbon as well as creativity. To deliver its green ambitions, the theatre has a sustainability/education arm, Green Arcola and a sister company, Arcola Energy; an energy technology incubator.

Over the last three years, Arcola, housed in a converted paint factory, has undergone a ‘green’ transformation, which, in addition to W+W, includes waste wood biomass boiler, natural ventilation system and an innovative LED lighting system, powered by solar photovoltaics.

Funded by a £1m grant from the Arts Council, plus additional support from donations and local volunteers, main renovation works took place in 2012, with Roca’s W+W installed last summer.

Design & Desire

Urban narrative Last month, the new Library of Birmingham celebrated its official opening ceremony, where thousands of members of the public attended to catch a first glimpse of the new building – the project’s completion has been hugely anticipated since it was given the go-ahead in 2007. Here, architect Mecanoo and structural & mechanical engineer Buro Happold provide an insight into the building’s outstanding execution.

S

ince opening in 1974, the original Library of Birmingham has become the most visited public building in the city and the busiest public library in the country. It houses an extensive anthology of books, photographs, historical archives and rare printed collections of both national and international significance. While the library served the city well for almost 40 years, the outdated building no longer met the

28

needs of the community. Commissioned

by Birmingham City Council in 2007, a new library is now providing a dramatic setting as a centre for knowledge and a place of entertainment.

The 35,000m2 library comprises an adult and children’s library, study centre, music library, community health centre, multimedia, archives, Shakespeare Memorial Room, offices, exhibition halls, café and lounge space and roof terraces.

Architect Francine Houben comments: “The building is formed with three stacked volumes, each connected to the city at a different scale – the lower volume and terrace relating to Centenary Square, the middle volume to the district and the upper volume to the city scale. The stacking of the library volumes creates an opportunity for outdoor gardens, each one relating to the city at a different scale.

“The lower terrace – The Discovery Terrace – overlooks Centenary Square and is the most public. In contract, the upper garden – The Secret Garden – has a more introverted, intimate atmosphere, reflecting its elevated position in the building. The sloping beds of the garden respond to the gentle slopes around Birmingham.”

Travelators and escalators dynamically placed in the heart of the library form connections between the eight circular spaces within the building.

The energy centre is also connected to the district heating scheme providing additional resilience to the building and to the network itself, contributing to the expansion of the low carbon district heating network in the area. Within the energy centre, a combined heat and power engine and absorption chiller provide cooling, heating and power.

Supplementary heating is provided from high efficiency gas boilers and cooling from high efficiency chillers utilising water towers with acoustic treatment to meet the onerous acoustic requirements for the REP Theatre. Additional free cooling is provided from a ground water cooling system that pumps water from the aquifer below Centenary Square to provide cooling to the areas utilising chilled beams.

The overall result for the library is a building that delivers an impressive 40% reduction in carbon emissions when compared to the Target Emissions Rate defined by the Building Regulations.

Flooring LVT flooring can be made to bespoke specifications to ensure that it is as wearable as necessary

Bespoke surfacing Whilst carpet has been an extremely popular flooring solution in commercial spaces over the years, luxury vinyl flooring is rapidly growing in demand. David Bigland, Managing Director of Moduleo explains why bespoke vinyl flooring is fast becoming more popular than mass-made carpet.

A

s technology has improved, luxury vinyl flooring has developed into the most stylish, durable and high-quality option for commercial solutions like office space.

Designed to reflect the unique patterns and textures found in nature, vinyl flooring tiles have a multitude of benefits and even outperform their natural counterparts in many areas.This includes better insulating properties, as well as being slip resistant, moisture-proof and soundproof.

LVT responds extremely well to the wear and tear of commercial and office use and as a result, can still look brand new years after being laid. Not only this, but in contrast to traditional carpet, LVT is

practically effortless to clean.

A wipe-clean top layer means that LVT flooring is not only low maintenance, but there is no hiding place in LVT for dust mites or any other allergens, it is also the perfect solution for those who suffer from allergies.

One reason LVT is one of the fastest growing floor products in the UK is because of its unrivalled durability. In offices for example, carpets can soon become tired and worn with years of stains and the wear and tear of heavy footfall. LVT flooring however, can be made to bespoke specifications to ensure that it is as wearable as necessary depending upon where it will be installed.

Moduleo flooring is available in our Select range for office use and the Transform range,

â–

The selection of designs available is practically limitless as designers are becoming increasingly imaginative with the looks and effects that they create

which has a thicker Protectonite PU wear layer, for areas which receive a heavier footfall.

Although carpets come in many different designs, textures and colours, they do not offer the flexibility of LVT, and this has had a significant impact on the flooring industry.

The beauty of modern LVT technology is that flooring can be created to be almost indistinguishable in appearance from its natural counterpart.

The selection of designs available is practically limitless as designers are becoming increasingly imaginative with the looks and effects that they create.This means that LVT can be equally at home in a modern, minimalist reception as it can in a cosy staff room.

In both new projects and building renovations, speed of installation is crucial.

Traditionally, the time and expense of floor-preparation and product installation may have been a concern for those considering LVT instead of carpet. However, there are now innovative new formats of LVT available which make installation a breeze.

One example of this is Click from Moduleo, which has been manufactured with a patented push down technology, allowing each piece to simply lock directly into place. This creates the same stunning finish, but means installation is much simpler and does not require any adhesive or time-intensive labour.

As the environment becomes a growing concern, most of us are keen to lessen our environmental footprint.

Traditional carpet production has been associated with the creation of volatile organic compound (VOC) emissions which are damaging to the environment.

LVT manufacturers vary in their ecocredentials, however Moduleo is proud to offer very impressive green credentials; including the creation of our very own wind-powered production plant in Avelgem, Belgium.

As our tiles are manufactured in Europe rather than the Far East, this also saves on unnecessary transportation and is therefore kinder to the planet. Moduleo products also consist of at least 35% of recycled material of verified origin and are themselves recyclable.

As technology has evolved, LVT has swiftly overtaken traditional flooring solutions due to its capacity to better-accomodate the latest trends in interior design whilst also providing the most practical and durable solution. Be it for office or commercial use: LVT is the premium choice for style, durability and longevity.

Making accurate U-value calculations Reviewing or making a U-value calculation for an inverted flat roof? Then these three vital considerations must be taken into account according to Dr Steve Johnson, Technical Manager for STYROFOAM insulation manufacturer, Dow Building Solutions.

W

e are all aware of the importance of U-values when it comes to the long term energy performance of well-constructed buildings. U-values can in general be calculated easily, and there is software available to make such calculations very quickly.

Anything that makes the job easier is welcome – but that doesn’t mean we should overlook vital factors which can lead to misleading calculations if not addressed. With the spotlight turning on the actual energy performance of buildings – not just the designed performance – ensuring U-value calculations are robust is a responsibility the industry must take seriously.

The inverted flat roof is a building element with many unique aspects, which must be tackled at the outset in order to avoid errors when making U-value calculations. Water vapour movement as well as heat transfer should be calculated, and in addition condensation issues need to be satisfactorily addressed if a robust design solution is going to be achieved. Let’s take each issue in turn.

Location, Location, Location Most people understand that two identical buildings, with identical U-values, would not deliver equal energy efficiency performance if built in different locations, due to differences in local climates. But you wouldn’t expect this to affect a U-value

calculation itself – or would you?

Inverted flat roof construction is simple in principle; just place the insulation above the waterproofing layer rather than below it, as would occur in traditional, warm roof construction. Interchanging the position of the waterproofing and insulation layers brings numerous advantages, but also introduces an additional mechanism for heat loss: rainwater can flow beneath the insulation boards and remove heat directly from the building fabric, before finally running off the roof and down the rainwater drainage outlet.

The inverted flat roof concept involves placing all the insulation above the waterproofing layer, however, designers from time to time may be faced with design constraints

Roofing

“Delta U becomes increasingly important as the U-values become smaller. It is particularly important for today’s low U-values”

ROOFMATE SL-A from Dow Building Solutions is for inverted flat roofs

Whatever the approach, there must be no confusion about the thermal conductivity value to be used for the thermal insulation material, since the overwhelming majority of the total thermal resistance which will contribute to the final U-value is down to the thermal insulation layer.

All insulation products have some degree of intrinsic variability in thermal conductivity. European Products Standards therefore take thermal test results and subject them to statistical analysis to create a level playing field. This improves the robustness of thermal conductivities used in calculations, and helps ensure that a consistent approach is used throughout the entire process. It also takes into consideration mechanisms such as aging into account.

This analysis delivers a so-called

“declared” lambda value in accordance with the relevant European norm for the insulation being considered. For extruded polystyrene (XPS) such as STYROFOAM this norm is BS EN 13164.

This declared lambda value is sometimes referred to as the 90/90 value, i.e. 90% of production achieves the quoted conductivity value with a 90% confidence level. Building designers have come to accept that declared (90/90) values for thermal insulation can be used as a design value as they represent a performance over a 25 year lifespan. However in inverted flat roof applications this declared (90/90) value needs to be additionally modified, by applying correction factors based on the unique end use conditions.

ETAG 031-1 states that possible moisture absorption over time needs to be determined by examining two particular

t

This effect is known as Rainwater Cooling, and it must be addressed when we do a U-value calculation. So how do we do that? First, calculate the U-value without taking it into account, and then add a correction (known as Delta U) to obtain the final U-value.

Obviously, the more rain which flows under the boards, the more heat is lost.

The additional heat loss due to Rainwater Cooling will therefore be dependent upon the average rainfall in the building’s location and the percentage of that rainfall which reaches the waterproofing layer.

BS EN ISO 6946:2007 outlines a method which can be used to calculate how much the U-value is affected by rainwater, and by how much we need to correct it. For an edge-profiled, interlocking board, a substantial proportion of rainwater can be expected to flow beneath the boards: European Technical Approval Guideline (ETAG) 031-1 stipulates that 75% can be assumed for calculation purposes.

This large percentage can be reduced by placing a water control layer (not to be confused with the waterproofing layer) over the insulation and beneath the ballast layer. Tests have shown that this can reduce water flow beneath the boards to typically around 5%, making a significant reduction to

the Delta U you would otherwise calculate.

Whatever the magnitude of the penalty that Rainwater Cooling brings, it needs to be correctly taken into account when making U-value calculations for inverted flat roofs.

Identifying differences When calculating U-values, we need to assess the individual materials which make up the construction element and know their respective thermal resistances, which can be derived from their thermal conductivity and thickness. If proprietary materials are used, a manufacturer should be able to provide relevant and – more importantly – accurate information for the calculation. In other circumstances, it may be acceptable to use generic information for the materials.

boards and thereby acts as an efficient vapour control layer. Surface condensation will also present a low risk, as the insulation boards maintain the roof’s waterproofing close to the building’s internal temperature.

Potential effects

Nevertheless, while condensation risks are low, they are not zero, and we need to consider what other physical mechanisms may contribute. As already outlined, rainwater is able to flow beneath the insulation boards, removing heat from the roof structure. This results in a sudden drop in temperature and can lead to condensation.

For concrete decks – which have a significantly large thermal inertia – the

The optimum location for insulation is the outside of the building structure: this minimises thermal issues and helps to ensure that the dew point is on the outside of the building.

mechanisms for water absorption: by diffusion and by freeze/thaw, because the efficiency of thermal insulation is impacted by the amount of moisture it contains.

Only when the moisture levels have been determined can the relevant correction factor be applied – calculated in accordance with BS EN ISO 10456 – to the declared 90/90 lambda value, in order to derive a relevant application design lambda value.

Adding these correction factors will mean an increase in the thickness of insulation required to achieve the same U-value. Ignoring them can lead to a significant underestimate of the amount of insulation required to achieve a target U-value.

duration and extent of deck cooling and therefore the consequent risk of either interstitial or surface condensation can be considered minimal. For lightweight decks, however, rainwater cooling can pose significant risks unless steps are taken to address it.

Strictly speaking, the inverted flat roof concept involves placing all the insulation above the waterproofing layer. However, designers from time to time may be faced with design constraints, and they may want to consider placing some insulation below the deck within the ceiling void.

Care must be taken with this approach, as increasing the thermal resistance below the waterproofing layer only increases the risk of condensation forming.

This increased risk cannot be offset by any ventilation of the insulation layer inside the building, as this would effectively provide a thermal “short circuit” and render the roof insulation ineffective altogether.

There are no hard and fast rules as to how much thermal insulation can be accommodated within a building before problems with condensation effects emerge. However, it is generally recognised that for an inverted flat roof design to perform effectively, the overwhelming majority of the insulation must be placed outside of the building and above the waterproofing layer.

In summary, yes, there is more than meets the eye when calculating U-values for inverted flat roof systems and bearing issues such as condensation in mind.

However, guidance is available to help ensure we all get it right – and help protect the reputation of the building industry as a whole.

The variation in height of the inter-connecting roofs means that some roof areas overlook the roofs of other part of the development

A degree of innovation University campuses have been one area of construction that have seen a significant investment across the UK to address the increasingly competitive nature of the sector. However, those financial pressures are still very real, prompting universities to balance the need for better facilities with the need to implement projects in the most cost-effective way possible.

A

t Huddersfield University, recent improvements to facilities include four new buildings, including a new sports hall, Dean’s office and corporate suite, designed by architects Watson Batty.The four buildings have been constructed with a single steel frame and all adjoin each other but rise to different heights varying from 2-4 storeys.To enhance the biodiversity and aesthetics of the development, green roofs were specified for three sections of the building, including the sports hall, and a warm roof was specified for the corporate suite.

The variation in height of the interconnecting roofs means that some roof areas overlook the roofs of other part of the development, with the lower roofs mostly shaded.This presented challenges both in terms of planting and drainage for the roofs and addressing those challenges became a team effort between the architects, the

38

roofing contractor, Cawston Roofing, the green roof supplier ABG and the waterproofing specialist, Kemper System.

While the intention for the buildings had always been to install a combination of green roofs on three of the four roof areas and a traditional warm roof build-up on the fourth, the architect had originally specified a single ply membrane for the project.

However, having used the Kemperol V210 cold liquid-applied waterproofing membrane from Kemper System for around 30 years, Cawston Roofing suggested to the architect that this would offer a more practical and durable alternative for a similar installed cost as the original specification.

Meanwhile, ABG had developed an innovative ‘blue roof’ drainage system, which puts a High Density Polyethylene (HDPE) reservoir under the growing medium to replace the more conventional SUDS system, reducing the installation time and avoiding

costly and time-consuming excavation of separate drainage tanks.

Explains Nick O’Mara from Cawston Roofing: “The Huddersfield University project demonstrates how important it is to consider specification decisions in a holistic sense rather than thinking about material costs in isolation. For the green roof system, avoiding the need for a SUDS system saved time, money and costs on site.

For the waterproofing membrane, a change to Kemperol V210 meant that we could be more flexible with the programme and more creative with the roof build up as well as providing an FLL certified root-resistant and robust waterproofing membrane with a guaranteed service life.”

For the three green roofs, Cawston Roofing applied Kemper System’s Kempertec EP primer direct to the concrete slab substrate and, once this had cured, the Kemperol V210 cold liquid resin was applied.

The Kemperol V210 resin saturates a nonwoven reinforcement fleece and cures to provide a seamless, monolithic membrane that is tough and permanently flexible.

ABG installed a 40mm deep ‘Blue Roof’ drainage reservoir onto each of the three green roofs which provides collection and storage or rainwater to irrigate planting during dry periods, and offers a continuous drainage layer across the roof structure with attenuation capabilities which helps control the discharge of storm water.

The corporate suite section of the building has a metal deck roof and here the roof build up featured a vapour control layer installed directly onto the substrate followed by Kempertherm warm roof insulation. Cawston Roofing prepared the insulated substrate with Kemper System’s Kempertec D primer and, once this had cured, applied Kemper System’s Kemperol V210 waterproofing membrane using the same wet-on-wet process as with the green roof areas.

Roofing, Cladding & Insulation

Kemperol delivers a factory finish The advanced chemistry of Kemper System’s innovative Kemperol V210 cold liquid-applied waterproofing membrane will help ensure efficient manufacture of fluorochemicals and fluoropolymer materials thanks to a roof refurbishment project at AGC Chemicals in Lancashire.

A

GC Chemicals is one of the world’s leading manufacturers of fluorochemicals and fluoropolymer materials, and its production plant not only requires a dry environment on the inside but also needs a durable roof surface on the outside to accommodate regular footfall from maintenance staff.

The concrete slab roofs on two production site buildings at AGC Chemicals had asphalt surfaces that were widely failing with a potential risk of leaking into the building below. This was evident by patches of blistering. Moreover, the seal around a number of redundant roof lights had also failed so AGC opted to refurbish the roofs as part of a general upgrade to the buildings and Kemperol V210, a cold liquid-applied waterproofing membrane from Kemper System, was chosen as a solution that could be applied quickly with minimum remediation to provide a tough, flexible and long lasting surface.

Castle Contractors stripped away the existing loose material before making good the failed areas using Kemper System’s ‘D’ Primer to prepare the surface; flooding the areas where the old substrate had been removed with special resins and graded fillers to create an even surface. The contractor then applied Kemper System’s Kemperol V210, a fleece reinforced resin based waterproofing system which cures to create a seamless, elastomeric, membrane that is durable enough to withstand regular footfall from maintenance teams and that also has an effective working life in excess of 25 years.

Comments Mark Atherton from Castle Contractors: “The original roof was in a poor state of repair and contained a wide range of roof details, including boxed off redundant roof lights and a brick parapet wall. By using the Kemperol system, we were able to apply a new waterproof membrane with minimal preparation of the existing substrate and could seamlessly apply the new membrane to the exact contours of the details on the roof for excellent leakfree waterproofing integrity.”

Roofing, Cladding & Insulation

A speedy route to compliance On 30th July 2013 the Department for Communities and Local Government issued a directive regarding conservatories and porches and whether they must comply with Building Regulations or whether they are exempt.

The decision of whether or not a conservatory or porch extension is exempt is ultimately a matter for Building Control bodies on a case for case basis, taking into account many factors.

Regulations demand certain parts of a structure be kept dry and free from damp.

In the case of an extension, conservatory or a porch attaching to an existing cavity wall, measures at the roof/wall intersection are necessary to prevent dampness in the external skin above the roofline, from

gravitating downwardly below the roofline where the external skin becomes an internal wall.

Preformed Cavitrays for insertion into existing walls arrest permeating dampness from gravitating downwardly and provide a warranted way to satisfy/regularise this particular construction requirement. Of the various types of Cavitray available – some of which have flashings already attached – the Type E for horizontal abutments and the Type X for sloping abutments are

manufactured by Cavity Trays of Yeovil.

Both types have been awarded European Technical Approval and LABC product type approval. When constructing an extension, conservatory or porch, approved Cavitrays offer a speedy route to regulation compliance and come with a performance undertaking for the benefit of architect, builder and client. *

Forbo’s flooring scores highly

Smart flooring products from Forbo have helped create a high quality learning environment

Products from Forbo’s Marmoleum and Sarlon acoustic vinyl ranges have been installed as part of a major development project at Alsop High School in Liverpool, delivering a contemporary finish in keeping with the specialist technology college’s modern ethos.

T

he project entailed the construction of a new state-ofthe-art facility housing classrooms, a sixth form centre and canteen, and extensive refurbishment of buildings dating back to 1926.

With more than 1700 students Alsop High School is the city’s largest secondary school. As architect Martin Shutt of 20/20 Liverpool explained: “With such a high level of foot traffic, the flooring needed to be hard wearing, resilient and cost effective.

We used sheet Marmoleum as the main flooring component throughout the upper levels. We’ve used it on many previous projects and knew it would meet these requirements, and it also helped us achieve a smart, modern interior that complements

the building’s contemporary design.

“We had strict sustainability targets to meet within the project too,” he added, “and Marmoleum was ideal in this respect, as it is made from natural materials and has a high recycled content.”

Enhanced performance Throughout the ground floor corridors and canteen, Forbo’s Sarlon vinyl was specified in order to achieve the required balance of enhanced slip resistance and acoustic performance. Sarlon Canyon delivers 15dB impact sound reduction, excellent indentation resistance and a slip resistance rating of R10. This range, with its subtle tonal design, is particularly popular within the education sector.

Forbo’s Safestep R12 was installed in the kitchen where there was a need to protect staff from slip hazards associated with food and drink spillages.

Safer Osmani, Business Manager at Alsop High School, said: “A fantastic new learning environment has been provided for our students. The focus throughout the project was on creating a high quality facility with a forward-looking interior and the smart flooring products from Forbo have certainly helped us achieve this.”

Hand-brushing removes pulpy softwood to expose natural graining and annual rings, which reinforce the natural look. Some designs are bevelled and smoked to add further distinction. Each design from the Collection features Kährs’ ethical, high performance construction. Based on Kährs’ original design, patented in 1941, it uses sustainable hardwood down to the floor’s joint.This method, alongside Kährs Woodloc 5S joint, provides greater stability, promotes fast installation and eliminates gapping throughout the lifetime of the floor. *

Hembuild systems central to sustainable community Exercising in silence Torshavn gymnasium in the Faroe Islands is a major addition to the existing municipal stadium. Gyms are often cold, echoing and not particularly welcoming places. However, for this project, careful consideration has been given to the function and performance of the room.

Instead of being cheerless, it positively encourages activities and social interaction with its warm colours, transparency, tactile materials and comfortable acoustics.To help achieve this, the architects opted to use Troldtekt acoustic panels to create a warm and friendly environment. Apart from the ceilings, they are also used on the walls, such as in the main room where a single row of panels have been spraypainted in situ. *

University College London has installed an innovative new boiler plant in its Torrington Place Building. The boiler house, supplied

by Atlantic Boilers of Lancashire, operates throughout the year at 95˚C flow and 75˚C return, and contributes to the UCL ring main that serves scores of buildings, large and small. Normally these ring main temperatures do not allow condensing, but the Atlantic RT add-on condensing exchanger leads to year round efficiencies of 92-97% GCV (102-107% NCV). For the UCL ring main, the result is that the Torrington Place boiler plant can lead all other ring main plants running at 95/75˚C and raise the overall efficiency. *

CVO Fire extends energy efficient gas fire range Being energy efficient has grown to be necessary for everyone as it can save you money. Anyone involved in building new homes, offices, schools and the like, or creating new environments, must consider ways to be energy efficient. Here, CVO Fire gives a few options to consider.

Flueless Gas Fires are 100% energy efficient with all of the energy supplied being returned to the room as heat. The CVO range includes ‘open flamed’ models in wall mounted, built in or traditional styles. Heat outputs range from 2.4kW to 3.5kW and running costs from only 10p/hour.

To achieve 80%+ efficiency, Chimney Gas Fires are a viable option. CVO Fire has recently launched five new, high efficiency gas fires for use with an existing chimney or

flue system. These gas fires are glass fronted and room sealed and are available in various design styles. These fires are perfect for new build or renovations and have heat outputs up to 5kW. Meanwhile, Balanced Flue Gas Fires are 75%+ efficient. These appliances are room sealed and are operated by a concentric flue pipe system. This allows for larger output appliances from 4kW to 14kW. Sizes are available from 400 to 1400mm wide

Enhanced integration with Baxi BIM library The Baxi Commercial BIM (Building Information Modelling) library provides data enriched 3D models for products and solutions in an extensive portfolio. This enables engineers to select and retrieve product requirements and import models directly into the BIM project on which they are working.

As well as dimensions, pipe connections and plant, the Baxi Commercial digital medium attaches product attributes such as outputs, efficiencies, weights, dimensions, in fact all the information necessary to enable a full virtual plant room ‘walk through’. BIM models in the library are also designed to support the commissioning process by helping the engineer to see exactly how an individual product fits into the integrated system along with its performance parameters.

The commissioning firm can call up the design details to use virtualisation *

and respected leaders in the commercial building services industry. BIM lends itself exceedingly well to demonstrating how these various technologies may best be integrated.

Digital representation should almost totally eliminate compatibility conflicts between the structure and the services, whilst making tendering an exact science rather than educated guesswork.

The Baxi Commercial BIM Library can be accessed by visiting http://www. baxicommercial.co.uk/bim/ and completing a simple registration process.

to interpret the design whilst work is in progress, whilst ongoing maintenance and facilities management can be vastly simplified.

The Baxi Commercial BIM library covers the extensive range of energy efficient products and system solutions provided by the component brands, Andrews Water Heaters, Potterton Commercial and BaxiSener Tec UK.

Drainage & Landscaping Tower Wharf, right on the Thames, is one of four unique installations for Cityscapes 2013.

Since August, a show garden from this year’s RHS Chelsea Flower Show has rematerialised, remixed into four new gardens in the same way as a song might be remixed by different producers.

Materials and plants for his latest project come from the Cloudy Bay Discovery Garden, which won Silver-Gilt at the RHS Chelsea Flower Show in May. For his remix, Matthew decided to create and plant out large-scale circular beds raised high at different angles.

In correlation to Best Show Garden at Hampton Court Palace, inspired by the principle that water is life and needs to be recovered, he researched the culverts market for the best products to work with.

Tubosider easily cut and shaped its products to requirement, creating a structure of five pipes 2600 to 1000mm in in diameter. Installing the whole garden took just two days, right on time for opening.

“The culverts worked a treat and make magnificent giant planters!” says Matthew.

Tubosider creates giant planters for South Bank

As one of the UK’s leading manufacturers of steel stormwater tanks, drainage pipes and culverts, Tubosider’s corrugated steel pipes are put to a wide range of uses, but few like this.

In a striking extension to its more traditional roles in water management, RHS Gold medal winning designer Matthew Childs has installed a range of Tubosider pipes as an

integral feature of his latest work – an urban Remix Garden on London’s South Bank.

Opened on 11th September, Matthew’s garden in the courtyard of the iconic OXO

Hörmann sectional garage doors gain accreditation

The break in resistance of Hörmann automatic sectional garage doors has been recognised by the award of Secured

by Design status. The accreditation applies to the combination of Hörmann insulated or solid timber sectional doors with the Series 3 ProMatic or SupraMatic operators.

The double skinned, insulated EPU and LPU doors both feature solid, CFC free polyurethane insulation that adds strength and rigidity to the door.With the EPU door the insulation is 42mm thick at the section joints and 20mm thick across each panel. For the LPU door this insulation is a constant 42mm thick, leading to even better thermal values.

The LTH solid timber doors are offered in a number of styles and buyers also have the option to have their own individual design recreated by Hörmann. These doors can be ordered in either Nordic Pine or Hemlock.

The ProMatic and SupraMatic operators

which are part of the Secured by Design accreditation both feature a mechanical lock. This unique automatic latching system makes it almost impossible to lever these doors open, and as it is a purely mechanical system, it remains fully functional even in the event of a power failure.

An additional security feature of the latest operators is the Hörmann BiSecur system.

This two-way communication between the hand transmitter and operator uses FM radio signals that rely on the same 128 bit encryption used for online banking. Not only does this system make the transmitters

more secure but also means that the signal is more reliable while extending operating distances. Another benefit of the system is that it includes a remote status query.

A wide range of styles and colours and even bespoke timber designs ensure there are doors to suit any home or project.

Additionally matching entrance doors are available including the Hörmann ThermoPro range which also has Secured by Design options. *

First homes must cater for TV savvy generation More than half (52%) of 18-34 year olds in the UK now expect access to a digital TV service as standard in their homes, according to a nationwide survey commissioned by Sky. Only a quarter of those surveyed still consider digital TV services a luxury in their home, and a mere 4% would settle for just terrestrial TV. Brendan Hegarty, Head of Sky Communal TV, comments: “Young people now expect a broader choice of TV programming at their fingertips. It is our job, working together with landlords and property developers, to make sure that future generations of home owners and tenants receive the services they demand.” *

removal of the existing furniture.

Peter Bright, Managing Director of BHC Furniture comments: “I believe this was our toughest ever project, with time a constant factor, the installation team proved admirable and we managed to finish with time to spare on the Bank holiday Monday.

We planned every stage down to the last second there was no room for delay!”

All site surveys and accesses were clarified, inclusive of vehicle size, restricted turning & loading/offloading schedules which had to coinside with road closures and a large crane which was being used for window cleaning on an adjacent building.The Method Statement and Risk Assessments were carried out and issued prior to commencement of works. All products were specified, quantities confirmed and orders signed off within 48 hours of the initial meeting. Floor plans were subject to change up to the day of installation.

Deliveries incorporated an empty second box system to load redundant furniture whilst removing new furniture from the front box. On completion of emptying the front box this was also utilised for additional redundant furniture and removed from site. *

BBA introduces CPS scheme for solid wall installers The BBA’s application to operate a competent person selfcertification scheme for the installation of solid wall insulation has been accepted by the Department for Communities and Local Government (DCLG).

The scheme covers the installation of internal, external and hybrid insulation systems and is an excellent complement to the BBA’s many Agrément Certificates for solid wall insulation systems.

The scheme will mean installers can self-certify that their work complies with Building Regulations without the need for a separate assessment by Building Control.

The BBA will issue a certificate to the installer’s customer and advise the relevant Local Authority that the work has taken place.

Being part of the scheme means installers can save time through not having to notify local authorities prior to commencement or completion of their work, BBA will notify after completion; save money as they don’t

have to pay a local council or an approved building inspector to check their work; and win more business as they can charge their clients lower prices as there are no building control fees to pay.

Membership is voluntary – installers can still use Local Authority Building Control and building inspectors if preferred.

As part of the CPS installers are assessed to ensure they meet the level of competence required before they’re registered. Once registered there will be ongoing inspections of their work to make sure the required standards are met. If you become a registered installer and you are also certified by the BBA under the Green Deal for either external wall insulation, internal wall insulation or hybrid wall insulation, then

the assessment of competence and ongoing surveillance is already undertaken by the BBA and no additional inspection is required.

The only additional fees are an annual registration fee to cover membership of the scheme and a small charge for each job self-certified and registered through BBA as Building Regulations compliant.

3M finishes create shimmering colourful surface effects Helifix presents solution for bowed walls The recently upgraded BowTie HD, from masonry repair specialist Helifix, is the ideal solution to the problem of bulging and unstable building walls. Fully concealed once installed, it rapidly restores structural stabilisation by securing the wall to internal joists or rafters without the need for any unsightly tie bars or pattress plates. Its heavy duty, unique rolled profile with selfcutting end, mechanically connects floor joists or roof timbers. It provides stiffness, generally without the need to install noggins or additional bracing and, once bonded into the masonry, reliably connects the walls to the internal wood frame. *
