s summers go, it feels like we’ve been short-changed somewhat. Last month’s floods and severe weather warnings caused devastation and disruption throughout – some parts of the UK even witnessed a month’s rainfall in one day. In light of July’s downpour, now seems like an opportune time to reflect on the savings and benefits that can be gained from systems that utilise unwelcome weather forecasts.

Rainwater harvesting is just one area of focus for water management. As significant contributors towards carbon footprint, new and existing builds are continuously under scrutiny regarding their water consumption. BREEAM ratings are determined through a variety of requirements – water use being one of them – therefore both public and private sectors have been forced to re-address their existing systems and look for alternative solutions to become more sustainable.

Readers can turn to page 26 to see just how one company is meeting the demands of existing builds striving to manage their water more efficiently. With its latest RainStore system, Kingspan Water outlines the greater savings that can be achieved without affecting water supply continuity.

Elsewhere in this issue, FC&A takes a look at the developments of the upcoming Timber Expo event – the annual showcase delivering unprecedented networking opportunities for professionals working within the timber industry. Promising to be even bigger and better than last year, the event has a whole host of special features and seminars lined up for attendees seeking to enrich and enhance their knowledge and understanding of this low-carbon construction material.

The Wales region includes three castles, eight mansions, 55 holiday cottages and five farms under direct management, amongst other properties

Sustainable preservation Over 400,000 buildings in England and Wales have listed status, and, being of historic importance, have traditionally been viewed as difficult or impossible to retrofit for improved energy efficiency. The National Trust has shown through its work in Wales that such properties can in fact be retrofitted, and is now expanding the work to its other regions.

T

he National Trust owns 29,000 buildings, most of which are historic and have listed status, and so cannot be modified in ways that significantly alter their visible appearance.

Energy use for heating and lighting is high

because of poor insulation and inefficient equipment, and the energy cost of £6.5m per year diverts funds from the core purpose of the Trust – to preserve heritage. However, in the past it has been assumed that nothing can be done to improve energy efficiency, due to

the historic nature of the buildings.

The National Trust is not alone in this situation – there are over 400,000 listed buildings in England and Wales, most of which are currently not energy efficient.

To tackle this problem, the Wales region of the National Trust has developed and implemented methods of improving energy efficiency without changing the character of its properties, and also changing staff culture to promote energy saving.These methods are now being rolled out across the whole Trust.

The Wales region of the National Trust was selected to pilot the energy efficiency work for the whole organisation as it had already made progress in this area, and had developed significant expertise within its staff.

The Wales region includes three castles, eight mansions, 55 holiday cottages and five farms under direct management, amongst other properties.The work is part of the National Trust’s ‘Fit for the future’ campaign, in which it aims to reduce its environmental impact while

too much heat. The National Trust has worked with several lighting manufacturers to find LED lights that meet their requirements and has made extensive use of a new ‘candle’ dimmable LED bulb, ideal for use in chandeliers, which was specially developed by Heritage Lighting.

Other improvements include more

efficient hand dryers in public toilets, improved tamperproof time controls for heating in holiday rental cottages and voltage optimisation. Heating systems have been improved as well, initially by more rigorous maintenance of boilers, and then by replacing gas or oil fired boilers with renewable sources of heat.

developing new business opportunities and empowering others to cut their impact too.

Before any changes were made to buildings or procedures, detailed monitoring of energy and resource use was implemented, so the benefits of the work could be measured and used to inform future decisions.The programme then moved on to analysis of the existing buildings, energy use, transport and methods of work, providing the information to make decisions about what steps could be taken to reduce environmental impact.

Following the analysis, a range of technologies was implemented, along with changes to the culture and behaviour of staff, to reduce energy demand and improve efficiency.

The National Trust carried out an environmental audit of its properties in Wales, and commissioned energy surveys of the properties. As expected, the main energy use in most buildings was for heating, due to their lack of insulation and poor draughtproofing. Thermal models identified where changes could be made, and thermal imaging was used to present the information in a visual way that could be easily understood and presented to non-technical staff.

Measures to improve efficiency were installed before those to generate renewable energy, as efficiency yields faster paybacks and saves more energy for a given investment. Heat loss has been dealt with through several methods; lofts have been insulated and secondary glazing installed, dramatically improving the airtightness of the buildings. Where secondary glazing is not appropriate for a historic building other measures have been taken, such as installing thick curtains or bringing existing shutters back into use, repairing them where necessary. Other appropriate draught proofing measures have also been taken for windows and doors.

Lighting the way Significant efficiency improvements have also been possible for lighting, as when National Trust properties are open to the public the majority of the rooms in them are lit for the whole day. Existing lighting was almost exclusively incandescent bulbs, resulting in high energy consumption – especially in rooms with chandeliers. The requirements for lighting in historic buildings that are open to the public are stringent, as the right atmosphere needs to be created.

The colour and intensity of the light and the appearance of the bulbs are important, and they must not be too heavy or generate

Greenhouse Biomass boilers have been a popular option as the National Trust owns and manages woodland and can therefore supply some of its own fuel. It is currently using 200 tonnes a year from its own estate in Wales, and is investigating what the maximum sustainable yield is. Heat pumps have also been used, both air-source and ground-source, and a marine source heat pump is currently under construction at Plas Newydd, on the Menai Straits. Renewable sources of electricity have been installed, including several solar PV and hydro power systems.

energy use and CO2 emissions.

The National Trust has also been taking action to replicate its work in other organisations. It has participated in numerous presentations and workshops on saving energy, involving the Society for the

Protection of Ancient Buildings, the Historic Houses Association, Historic Scotland, the Prince’s Regeneration Trust, the Irish Historic House Association, the Museums and Libraries Association, Pembrokeshire National Park Authority and others.

The potential for replicating the National Trust’s work is significant; there are over 400,000 listed buildings in England and Wales, many of which could benefit from the same measures to save energy while preserving their historic nature.

Widening the scope, there are 5.3 million homes in Great Britain that were built before 1918; these usually have solid walls and are considered hard to treat when it comes to improving energy efficiency. These homes could also benefit from what the National Trust has learned about how to analyse energy use and implement measures to save energy while taking account of the age and construction of the building.

â–

By April 2012, the National Trust in Wales had carried out a range of efficiency and renewable energy work in the 300 Welsh properties it has direct responsibility for.

It had insulated eight mansion properties and 95 smaller properties, and installed 18 ground-source heat pumps, 18 biomass heating systems, three log heating systems and 12 solar water heating systems. It had also installed nine solar PV systems with a combined capacity of 313kW, and over 250kW of hydro power. More solar PV and hydro schemes are under construction at present, including a 650MW hydro site near Snowdon, which will generate 1900MWh/year.

The work, which the National Trust has piloted in Wales, has recently been given board approval to be rolled out rapidly across all the other regions.The system for monthly meter readings is already in use in all regions, and included in staff key performance indicators. National Trust properties in Wales represent a small proportion of the total number, so the roll-out to other regions is expected to result in significant reductions in

Eco-friendly learning environment In collaboration with Liverpool City Council and designers 2020 Liverpool, Morgan Sindall has recently delivered a brand new sustainable learning facility, in the form of Croxteth Community Primary School.

The new school replaces an old building and encompasses a wide range of innovative, sustainable elements – aiding children’s development and enhancing their learning experience through the provision of a custom-built, eco-friendly school building.

The project included the demolition of the old primary school following the construction of a new single-storey school

building with classrooms arranged around three central courtyards with direct access to outdoor play areas.The development included the construction of a library, art and music rooms, a synthetic area for sport and games, two grass sports pitches, a large community room and a crèche.

Sustainability in Development is currently on track to achieve a BREEAM rating of ‘Very Good’.

One of the school’s most visual sustainable features is its striking sedum roof.Three of the building’s south to south westerly elevations have a green roof system which is covered with sedum turf.The turf changes colour with the seasons and converts carbon dioxide to oxygen, creating a practical, beneficial roof space, which absorbs rainwater and provides insulation.

Three internal courtyards link to classrooms and circulation areas, one of which is an open area with tiered seating, while the other two internal courtyards are covered by polycarbonate sheeted, steel framed roofs which create a tropical greenhouse effect within.The two tropical areas contain planters with various exotic plants and fruits and vegetables.

Two external canopies provide covered play areas for pupils outside. One of the canopies is covered with photovoltaic panels, which convert sunlight into electricity which is then fed into the school’s electrical system.

Ian Weir, technical director from 2020 Liverpool, says: “Croxteth Community Primary School is designed to be an organic building, from the green roof which will change colour with the seasons, to the flexible learning spaces and the environmental features which will help support education as well as saving energy.

It’s going to be an inspiring place in which to work, to learn and to grow.”

A ‘smart metering’ system display panel which is mounted in the school’s main circulation area monitors and displays information about power and energy usage and is used as part of the school’s curriculum to raise children’s awareness of sustainability.

The school also includes a number of state-of-the-art facilities including an ‘immersive learning space’, featuring a projector which can transmit images and film across an entire wall, and special mood lighting which enables teachers to transport pupils to anywhere in the world.

Councillor Jane Corbett, cabinet member for education, says: “The new school has transformed education for children in the area and is also a brilliant facility for the whole community to use. It is an absolutely fantastic asset for Croxteth and, combined with the already excellent teaching at the school, is giving a bright future to hundreds of young people.”

Inspiring facilities The whole building is insulated to a very high standard and glazed with high tech inert gas filled double-glazed units. All of the building’s systems are fully integrated and controlled by the building management system.

Barry Roberts says: “We have thoroughly enjoyed working closely with 2020 Liverpool, the school and Liverpool City Council to create this fantastic learning environment which pupils will benefit from and enjoy for

many years to come.

“The innovative sustainable elements of the school will not only enhance the children’s learning experience but also benefit the environment, and we are delighted to be on track to achieve a BREEAM rating of ‘Very Good’ for this project. This development will provide a superb learning and recreational facility for the school and the local community and we are delighted to be celebrating the handover of the project to the school with this special ceremony.”

John Pass, project manager for Morgan Sindall, says: “It has been a pleasure to work with the head teacher, the staff and pupils

and we are all very proud of the facility we have created. I am sure that 2020 Liverpool’s cutting-edge design, combined with our high quality construction, will provide a superb learning facility for many years to come.”

Morgan Sindall has completed a number of education projects in Liverpool, including Park Brow School in Kirby and Park Primary School in Wallasey.The company also constructed the city’s largest school, Alsop High School in Walton, which was the first scheme of the planned Liverpool Building Schools for the Future programme.

The building is heated by ground source heat; 17 135 metre-deep bore holes under the school’s south playground are linked together by underground thermal fluid filled pipework, which runs back to a central plant room where the pipes are connected to heat pumps. The heat pumps extract the heat from the incoming ground source fluid and this is used to power the school’s under-floor heating system. There is also a back-up gas powered boiler which could be used in the event of a failure with the ground source system.

The school also benefits from a natural ventilation system.Wind catchers have been installed on the school’s roof, some of which incorporate solar panels to power their own internal fans. Many of the school’s windows also have opening lights with power actuators, which are linked to temperature and C02 sensors and which are controlled by a central building management system.

Details in the fabric

As ‘fabric first’ is becoming the widely accepted approach to creating low energy, low carbon buildings, Neil May, a director of the Passivhaus Trust and the Good Homes Alliance and CEO of Natural Building Technologies, argues that it’s essential to employ a systems approach in designing a building envelope to maximise performance.

that the building actually delivers on its design specification in practice.

Specifically, it’s essential to take a

systems approach to the delivery of an effective building envelope. This means that all of the materials used in the structure must be selected so that they complement each other and work as a single system, rather than simply being a ‘pick list’ of individual building components.

A united front

Neil May is CEO of Natural Building Technologies (NBT) and a founder and director of the Good Homes Alliance and a director of the Passivhaus Trust. Neil sits on a number of Government Committees including the Technical Advisory Group for the Code for Sustainable Homes and the Zero Carbon Hub.

Simplifying building design, generally, is also an important factor in translating design performance into reality. Far too often, supposedly low energy, low carbon buildings, when tested, have failed to live up to their design promise.

Much of this can be attributed to over complexity of design not being able to be delivered by the current skill levels in the construction industry and over-reliance on new and unproven technologies that depend on occupant behaviour to function efficiently. Designs which employ building systems that accommodate the current skill levels within the industry are far more likely

reating a well-insulated, coherent building envelope has gained widespread industry acceptance as the fundamental first step in delivering energy efficient, low carbon buildings.

An energy-efficient, airtight structural shell that minimises the need for space heating means that CO2 emissions will also be minimised, without relying on complex and expensive renewable technology. By designing energy efficiency into the building fabric, and specifying materials that have proven longevity of performance, buildings constructed today will still be delivering their ‘as designed’ energy savings in 50, or even 100, years from now.

However, in specifying the building products to be used for wall and roof constructions, there are a number of other considerations that need to be taken into account to safeguard the long-term health of the structure and its inhabitants, deliver a comfortable living environment all year round and ensure

wall studs in timber frame constructions without leaving gaps. Materials and systems that do not rely on highly skilled craftsmen to achieve their theoretical performance are more likely to deliver an energy efficient building than those materials and systems that require very precise or complex installation.

Most importantly, the wall and roof systems used must deliver ‘breathability’ to the building fabric, so that any moisture vapour that gets into the structure is dealt with in such as way as to protect the building from structural damage due to interstitial condensation and to protect the building’s inhabitants from the health side effects of damp and condensation. These can include asthma and other autoimmune diseases, resulting from mould growth and other pathological organisms.

To achieve true breathability all of the key elements of the building envelope must be breathable, including the insulation, as well as finishes, such as renders, plasters and even paints.

Breathability is equally important, if not more so, in refurbishing and upgrading the energy performance of existing buildings. In the case of buildings where the external walls are insulated from the inside, the situation becomes critical. By installing standard insulation against an existing wall, warm moist air will travel through the insulation and condense when it hits the ‘cold’ inside face of the external wall. If this happens, the same consequential outcomes outlined above will occur. Only by using a specialist insulation system, such as a made-forpurpose woodfibre system, that is able

to avoid the formation of interstitial condensation in the wall structure and utilise the hygroscopic and capillarity of the fibre to absorb and return the moisture back into the room, will a safe and effective insulation solution be delivered.

Advanced insulation As well as providing effective insulation to minimise space heating, it’s equally important that the building fabric has sufficient thermal mass to mitigate the effects of solar gain in summer to avoid overheating. This means, for example, that in a timber frame structure, the insulation and wall/roof finishes must provide the thermal mass that the structural elements (i.e. the timber frame) don’t. It is also possible to construct masonry wall systems using insulating clay blocks that deliver both good thermal performance and thermal mass, and, indeed, are also breathable – such systems are widely used throughout Europe.

Finally, in delivering a truly low carbon building, the building materials themselves must be from sustainable sources, with low embodied energy.

Fabric first is the natural and sensible starting point for the delivery of low carbon, energy efficient buildings.

However, it is only by taking a holistic, systems approach to the design and practical delivery of a building envelope that we can ensure a ‘fabric first’ design delivers an effective and healthy building in practice.

to deliver the desired results.

To optimise energy efficiency, the building envelope system needs to minimise cold bridging. Good practice methods in helping to achieve this include the use of homogenous building materials to simplify design details at junctions and openings, enclosing timber or steel frame structures within a continuous layer of (breathable) insulation boards, and using insulation materials that fully fill the space between

HVAC

Implications for coastal heat pumps When an air source or ground source heat pump is specified for a coastal property, there are certain factors that should be considered as part of the system design, says Nu-Heat Underfloor & Renewables.

the heat pump itself, as this will be in a plant room, but for the energy source. For borehole installations, Nu-Heat calculates the amount of energy that the heat pump is expected to harvest from the ground each year in kilowatt-hours, as well as the steady state peak power draw in kilowatts. A borehole contractor then uses these two values to determine the amount of ground collector required while considering the thermal properties of the ground beneath the property. In some cases, thermal response testing may be necessary.

In a coastal location that is very close to the sea, it is possible for the tide to affect energy levels.With one recent installation, a higher heat extraction was available at low tide than high tide, most likely because the natural water-courses are held back during high tide, reducing the warmth of the ground. In this instance Nu-Heat specified additional boreholes to meet performance requirements.

Sand is not the best type of soil for ground loops as it is free draining and is unlikely to stay wet for long. Additionally, sand granules are unevenly-shaped, allowing gaps of air to form and, as air is also insulative, the combination is not ideal, so for sandy soil, the best option is boreholes that reach beyond the sand layer to more moisture retentive and less insulative soil.

With a ground source heat pump utilising a horizontal ground array, it is again the moisture content of the soil

that will affect performance, as wet soil is conductive and dry soil is insulative.This is true anywhere in the UK due to rainfall and damp conditions and must be taken into account when sizing the array.

For either type of heat pump, an exposed coastal location such as on a cliff top facing out to sea may impact on heat loss calculations, so an increased ‘exposure’ figure should be included.

As with any heat pump installation, ultimately it is the design of the system that will ensure energy efficiency and high performance.

oastal refers to a property that is located within 4 kilometres of the sea. Such a location should be flagged up by the estimator who will look at property location in order to size the heat pump (in accordance with MCS).

For air source heat pumps located on the coast, the main issue is that salty air may corrode the heat exchanger within the heat pump.The solution is straightforward, and every air source heat pump that NuHeat specifies for such a location is treated with Blygold anti-corrosive coating. Blygold has traditionally been used to protect HVAC coils, and is ideal for air source heat pumps. One coating should last for five years or more with minimum maintenance.

With a coastal ground source heat pump installation the considerations are not for

art of Wombwell’s awardwinning Brunel Quays scheme, the Old Carriageworks comprises eight loft style apartments, 10 offices and a state-ofthe-art dentist’s surgery within the grade II listed former Brunel Engine House on the banks of the River Fowey. The building sits in the kind of idyllic spot that developers’ dreams are made from, but its historic importance as the location where the UK’s first rolling stock was repaired and maintained meant that the design team had to contend with the building’s limitations as well as realising its potential.

One of the key challenges of the development programme was the need to refurbish the roof without altering the roofline. The issue was business critical for the developer: the building’s

properties should conform to Part L building regulations, which would require installation of insulation in the new roof.

Craig Thomson from Wombwell Homes explains: “Any heritage building represents design challenges and we were always committed to preserving the authentic appearance of the building. Even a minor change to the roofline can have a dramatic effect on proportions so we knew we had to find an insulation solution that would bring the building up to modern standards of comfort and environmental performance without compromising on a sympathetic redevelopment.”

The solution that the developer found was TLX Gold reflective insulation from insulation specialist, Web Dynamics.

An all-in-one breathable multi-foil and heavy duty roofing membrane, TLX Gold

Roofing, Cladding & Insulation is designed both to act as a thermal barrier and to replace roofing underlay, providing an efficient insulation option whilst fitting into confined roof build ups with insufficient space to accommodate conventional insulation and roofing underlay. The innovative technology sandwiches a core of PET wadding interleaved with reflective films between a high performance breather membrane top layer and a bottom layer that reflects infra-red rays back into the habitable space. The result is a slim insulative layer that minimises heat loss in the property whilst preventing condensation.

Slimline solutions

The ethos of the scheme involved preserving as much of the original material as possible

membrane to size to fit the size and shape of the roof exactly. Once it was in place, the contractor installed counter battens onto which the new slate roof was fixed. The all-in-one process for installing both breather membrane and insulation not only offered a slimline solution to improving the thermal performance of the building but also reduced the time and labour requirements on site.

The result is a roof that looks exactly like the original roof of the historic building, however it is not only watertight but is also breathable and well-insulated.

Mark adds: “There is a widely held assumption that the only way to achieve thermally efficient buildings is to construct new ones but that attitude is both environmentally and culturally disastrous. This project proves that, with the help of cutting edge building

materials, it is possible to preserve our built environment heritage and make it fit-for-purpose as a contemporary building too.”

■

“The secret,” explains Mark Seddon, sales director from Web Dynamics, “is that all the layers within the product are breathable so moisture passes through freely. The advanced technology has a European Technical Approval (ETA) awarded by the Deutsches Institut fûr Bautechnik (DIBt) in Berlin and also complies with the recently introduced BS EN16012:2012 European standard for reflective insulation, providing specifiers with peace of mind that it will not simply address the challenges of maintaining an existing roofline but will also fulfil their requirements for thermal performance too.”

To carry out the roof refurbishment element of the re-development scheme, roofing contractor, WC Roofing, first stripped out the existing roof completely, including removal of all the existing slates. The ethos of the scheme involved preserving as much of the original material as possible, however, so the strip out only went as far as the existing timbers, the contractor then had to find a way of laying the TLX Gold between the existing wooden boards which covered the beams and the new slate roof, while ensuring that there was plenty of free air movement between the two roofing components.

Mark continues: “The timbers were in good order so instead of replacing them the decision was made to re-felt over the top to provide a waterproof layer between the breathable membrane/ reflective insulation. Battens were then installed and the TLX Gold was laid over the top of this structure.”

To fit the TLX Gold, the contractor simply had to cut the insulation

Legal & Business

According to Hörmann’s Alan Jenkins, there has been considerable confusion over CE marking of industrial doors, since both manual and automatic doors fall under different directives. Manual doors are covered by the Construction Products Directive while automatic doors are under the Machinery Directive.

F

rom 1st July 2013 this will change, when all doors intended for installation in a building – and for which a harmonised EN standard exists – become subject to the European Construction Products Regulation (CPR). This will make it a criminal offence to place a construction product on the market anywhere in the EEA without a CE mark.

This means that manual doors and automatic operators will all be CE marked by the manufacturer or supplier.

However this is where care needs to be taken.

In the first case it must be stressed that CE marking does not signify that a product is fit for purpose; it simply

24

means it complies with essential health and safety requirements of the European single market legislation.

Assuming that the door chosen has been correctly specified for the use to which it is to be put, the confusion comes when a door and automatic operator are sourced independently.

Both will be CE marked under the new legislation but this does not mean they are compatible.

In this instance, the installer of the door is deemed to be the ‘manufacturer’ of the completed door and needs to CE mark the ‘new’ door. In order to do this they need to create a ‘technical file’ and issue a declaration of conformity. The technical file protects both the installer

■

False sense of security

and end user since it is proof that the door and operator are compatible and have been fitted correctly. If this combination of door and operator have been type tested by either manufacturer they will be able to supply documents to support this. Alternatively, documentary proof that the specifications of the two components are compatible and suitable will suffice.

Safety and liability are the key issues here. There have been a number of serious and fatal accidents that has prompted the Health and Safety Executive to issue guidance since they consider that industrial doors pose particular health and safety risks.

A simple solution is to source all the components from a single supplier who has already “type tested” the operators and doors, to ensure compliance with the highest applicable standards. In this case where the manufacturer supplies the powered door as a ready to assemble kit, then they can apply the CE mark.

Even in this case, should the installer make structural modification to the door, or any changes that may require further risk assessment, then the installer will have sole responsibility to create the technical file and CE mark the product.

All specifiers and contractors should be aware of this potential pitfall, and ensure the correct procedures are followed both on new developments and refurbishment projects.

lower water bills.The latter will also benefit from another government scheme – the Enhanced Capital Allowance.

Given the obvious environmental and financial benefits afforded by rainwater harvesting and the need to improve the environmental performance of existing buildings, Kingspan Water has been hard at work at solving this conundrum.

Supply continuity The upshot is RainStore, an above-ground system that has just been launched through a number of pilot schemes.The new retro-fit system can be installed onto a wide range of buildings from offices and schools, to prisons – even aircraft hangers – however, they are not yet suitable for a domestic home installation.

Earlier this year, a school in the West Midlands became the first academic institution in Britain to have a system fitted onto an existing building. Campion School, a mixed comprehensive in Leamington Spa, has had a RainStore system installed – a move that is expected to reduce mains water usage by up to 85% and save around 250,000 litres per year.

It collects water from the roof of the

sports centre and uses it for flushing WCs within the block. The rainwater is stored in a 5000 litre tank outside the sports hall, and if there is insufficient rainfall to meet demand, the system will automatically default to using mains water, ensuring total continuity of supply. A Kingspan Water Vision remote monitoring pack provides information about its operations to a wallmounted Control Panel – making installing, managing, and maintaining it easy to do.

Within the Control Panel is a GSM card.

A unique web address was set up for the school, which can be accessed from any computer with wireless internet access, so that the pupils can see how much water they are saving.

For those considering retro-fitting rainwater harvesting onto an existing building or portfolio of buildings, the initial steps include a free assessment of the property’s suitability as well as an audit of the level of savings in an average year. This is based on a number of variables such as the annual rainfall in the region, the size of the roof area, the size of the storage tank, WC usage levels etc.

■

W

ithin the construction industry, sustainable water management has been on the agenda for a while.The Code for Sustainable Homes, for example, tackles the issue of mains water consumption head on, requiring mains water usage to be restricted from an average of 150l to 80l per person/day by 2013 for public sector housing and by 2016 for private sector housing.This is over and above the recently introduced limit imposed within building regulations (Part G) which requires usage levels to be reduced to125l per person.

BREEAM, similarly, places a heavy emphasis on reducing mains water consumption to achieve an excellence rating.

These are targets that would be hard to achieve without the installation of watersaving devices – such as water-efficient washing machines and aerated taps – and, most particularly, rainwater harvesting. Its rapid take-up and success as a technology has been broadly as a consequence of its proven ability to reduce the amount of water used by householders by more than 50%, and by commercial users by as much as 80% – which clearly also translates into

Design & Desire

Bay South Garden is built on reclaimed land, a low lying, flat area on the shore of Marina Bay

Cool cultivation

Two of the largest climate-controlled conservatories in the world have been constructed as the architectural centrepiece of Singapore’s new 54-hectare Bay South Garden, the first completed part of the spectacular Gardens by the Bay project.

L

ocated in Marina Bay, Gardens by the Bay is a key project in delivering the Singapore Government’s vision of transforming Singapore into a ‘City in a Garden’. At a total of 101 hectares, the

At the heart of Bay South Garden is the £350m Cooled Conservatory Complex, which is the focal point of the Gardens

Gardens by the Bay project comprises three distinct waterfront gardens – Bay South, Bay East and Bay Central.

Masterplanned by UK-based landscape architecture firm Grant Associates, this lively and vibrant garden showcases the

best of tropical horticulture and garden artistry with a mass display of tropical flowers and coloured foliage and more.

At the heart of Bay South Garden is the £350m Cooled Conservatory Complex, which is the focal point of the Gardens.

The two main Conservatories, designed

by Wilkinson Eyre Architects, cover an area in excess of 20,000m2 and are among the largest climate-controlled glasshouses in the world. They provide a spectacular, all-weather attraction and comprise a 1.28-hectare cool dry conservatory – the Flower Dome – and a 0.73-hectare cool moist conservatory – the Cloud Forest.

Each has its own distinct character, but both explore the horticulture of those environments most likely to be affected by climate change.

The Flower Dome tells the story of plants and people in the Mediterranean climate zone, and how the plants cultivated in these regions will gradually become endangered as temperatures rise.

Climate control To maximise the daylight entering the conservatories, the gridshell is constructed from manufactured steel members that are triangular in section.These standard members are linked at plate steel nodes, designed in standardised ‘families’ to lower manufacturing cost whilst efficiently accommodating the changing geometry of the building.The ribs, which are anchored into concrete ‘shoes’ at ground level, are painted off-white to reflect light and heat, their sections tapering along their length in relation to the loads placed upon them.

Bay South Garden is built on reclaimed land, a low lying, flat area on the shore of Marina Bay. In the absence of a natural landscape the conservatories are

envisaged as landforms, a pair of artificial landmarks that prominently address the bay and the skyscrapers of dense urban districts around it.

A tiered approach has been taken to the energy design of the Cooled Conservatories with as much environmental control achieved through passive means before resorting to highly efficient, active systems.The principal design challenge of the Cooled Conservatories is the conflicting need to maintain the high light levels required by the plants whilst minimising the associated solar heat gain.

The form of the biomes is optimised structurally but also works well environmentally by containing a large volume within a relatively small surface area. In addition the Flower Dome is tilted forward so that it leans over towards the Marina Bay; the north facade is therefore self-shaded and never receives the full glare of the sun.

The envelope is critical to the success of the system: the structure has been designed to cast as little shadow as possible whilst highly selective glass is used to filter out as much heat as possible.Thanks to a low-e coating, the glass has a high visible light transmission coupled with a low solar heat gain coefficient (SHGC). In practice this means approximately 64% of the available light is transmitted into the building with only 38% of the corresponding heat gain.

Singapore is often overcast but even a cloudy sky transmits enough light for the exhibited flowers to bloom.When the sun does come out, deployable shades are used to control the light levels and limit the heat gain.These automated fabric shades are concealed within the arches so as to not cast any extra shadow when not in use.

Inside cool air is delivered at low velocity, trickling in and between the planted displays.This collects in pockets of the shaped internal landscape, providing

to the baobab and pachypodium trees in the Strange Worlds area, the visitor is presented with a unique collection of plants. The landform of the conservatories draws inspiration from Mediterranean landscapes and evokes the language of dry, sun-baked hillsides punctuated with rocky terraces and stony outcrops, and the intimate bond between land, geology, vegetation and cultivation. At the centre of this permanent display is the Flower Field – a vast carpet of flowers in bloom, which will change seasonally.

The Cloud Forest highlights the relationship between plants and the planet, showing how the warming of the cool tropical cloud forests will threaten biodiversity. With a smaller footprint but greater height than Flower Dome, it has at its heart a planted ‘Mountain’ from which a 35m high waterfall drops.Visitors can experience the forest at different levels from a Cloud Walk, a Canopy Walk and the Forest Floor and Ravine Walks.

Both conservatories have a dual system structure of gridshell and arches to permit as much light as possible through to the planted displays within. The gridshell portion is very fragile (like an egg) and is designed to only support its own weight and the weight of the glass. Wind loads are resisted by the arches that are set away from the surface of the envelope, and arranged radially in line with the geometry of the gridshell. This structural combination creates a distinctive, lightweight clear-span structure which, in the shallower slope of the Flower Dome, is thought to be among the largest gridshells in the world.

The Supertrees are embedded with sustainable energy and water technologies integral to the cooling of the Conservatory.

Given the equatorial climate, the grove of Supertrees will help to ameliorate discomfort by providing shade and shelter with the canopy.The Supertrees support a bar at the top of the tallest tree (designed

by Wilkinson Eyre Architects) and an aerial walkway experience 20m above the ground (designed by Grant Associates).

Superior structures In the day, the Supertrees’ large canopies provide shade and shelter. At night, the Supertrees come alive with lighting and projected media created by Lighting Planners Associates. A 128-metre-long aerial walkway connects the two 42-metre Supertrees in the Supertree Grove to enable visitors to take in a different view of the Gardens from a height of 22m.

The 50m Supertree has a treetop bistro designed by Wilkinson Eyre offering a panoramic view of the Gardens and surrounding Marina Bay area.

The Supertree comprises four major parts created by structural engineers Atelier One: reinforcement concrete core – inner vertical structure that upholds the Supertree; trunk – a steel frame attached around the reinforcement concrete core; planting panels – installed on the trunk in preparation for the planting of the living

skin; canopy – shaped like an inverted umbrella, the canopy was assembled and hoisted via a hydraulic jack system (with the exception of the 50m Supertree canopy assembled at its final height).

The Supertrees were planned from the outset to showcase innovative environmental technologies and to become an integral part of the overall site environmental systems. In addition to the creation of habitat and shaded spaces through the use of vertical planting, some will have photovoltaic cells to harvest solar energy, others include rainwater harvesting and some will be integrated with the Cooled Conservatories and energy centre to serve as air exhausts.

Paul Baker, project director at Wilkinson Eyre, says: “Sustainability was our starting point for Bay South Garden.

To house an organisation focused on preserving ecology in a building with a huge carbon footprint caused by air conditioning would have been madness.

Completing the Conservatories is an extraordinary technical achievement, which wouldn’t have been possible without the comprehensive design brief, the vision of NParks, the expertise of our partners and the close working relationship we enjoyed.

“In my opinion, our design represents an unprecedented integration of sustainability principles into a structure of this size. This is a remarkable project with staggering ambition. It will play a big part in Singapore’s future, not just as a centre for trade, but also as a travel destination.”

comfort to the visitors and – most importantly – the right growing conditions for the plants. Only these lower, inhabited levels are cooled. In the space above the planting and people the air is allowed to stratify according to temperature and a reservoir of hot air collects at the top of the dome.

Fresh air is drawn into the plant rooms and dried with a dessicant prior to passing through conventional chillers.The dessicant reduces the amount of energy required to cool the air but itself becomes saturated with extracted moisture.The hot air collected from the top of the glasshouses (along with surplus heat from the on-site biomass boiler) is used to regenerate the dessicant by driving off the moisture.The biomass boiler is fuelled entirely with green waste collected from around the city’s national parks and creates sufficient energy to cool the conservatories.

Additional highlights include the 18 unique Supertrees. Designed by Grant Associates as tree-like structures between 25 and 50m in height, the Supertrees are

banks disappeared overnight. However, having quickly secured a partnership with Resolution Property, the Brewery Square Development Company was born.

The development’s first contractor then became a casualty of the recession.

Although the first phase of the development – including a health centre, retail space and

the conversion of the Eldridge Pope building into apartments – was already completed, it looked like the second phase was going to be severely delayed.

This was when Leadbitter came in.

With experience in building mixed use developments throughout southern England and Wales, Leadbitter demonstrated very quickly that it was more than capable of hitting the ground running and delivering a high quality development.

The contractor was in a unique position of being able to bring the financial security of a national operator together with extensive local knowledge, having recently started work on the building of a new sports centre for Dorchester.

“It was vital we found a quality contractor that was financially stable, had the ability to jump into the saddle and take the project forward at such short notice,” explains Andrew Wadsworth. “A presentation by Leadbitter showed us that they had the skills, ability, appetite and will to take over the project quickly and deliver the quality of build required.”

In the space of just 17 months, the second phase of the development is well underway, and Brewery Square looks set to continue to go from strength to strength.

rewery Square is a 21st century redevelopment of a dilapidated Victorian industrial site that was, until the Brewery Square Development Company came along, a poor shadow of its former self.

But now it is well on the way to becoming a cultural, retail and leisure destination for a large part of Dorset.

Derelict listed buildings are being turned into high specification apartments, together with a cinema multiplex, two hotels and a theatre.

Built in 1837, the Eldridge Pope Brewery was originally designed by WR Crickmay, the architecture practice for whom the town’s most famous son, Thomas Hardy, worked until he became a full-time writer in 1872.

Sadly, as modern brewing methods took over, the Brewery became outdated and gradually the buildings fell into disrepair.

That is when Andrew Wadsworth and Robert Ackland formulated their vision for the Square’s redevelopment.

Andrew Wadsworth explains: “We researched our market thoroughly and examined the profile of those who want to live in high quality apartments such as these. People don’t want to use their cars to access amenities, so it was vital that we provided them with what they want

HVAC

A home that has been installed with Low-H20 radiators can emit as much as a ton less CO2 each year

Dynamic design Phil Marris, Managing Director of Jaga Heating Products, examines why radiators with Dynamic Boost Effect are the most attractive solution for an environmentally friendly refurbishment.

I

n recent years there have been two major changes in the domestic radiator market. Firstly, building occupants are placing increasingly value on attractive, stylish radiators, and are willing to invest for the right look.

Secondly, and more recently, there has been a huge increase in the demand for energy-efficient heating solutions.

The latter trend has been driven by various converging factors. Of course, not only are we all increasingly aware of our collective duty to protect the fragile natural environment, but new regulations are in place to cut Britain’s CO2 emissions in accordance with international climate change initiatives.

Part L of the new Building Regulation (2010) aims to reduce CO2 emissions by 25% over Part L1A 2006 – which corresponds roughly with the trigger point for Code for Sustainable Homes

34

Level 3, in line with the government’s strategy for getting new-build dwellings to zero carbon by 2016 – is the most pertinent to our industry. Heating is the key to hitting these targets – figures from the Ground Source Heat Pump A DBE product delivers the required room temperature up to nine times faster than a standard radiator

Association assert that 40% of CO2 emissions are derived from the heating of buildings. It is therefore no surprise that installers are increasingly turning to energy-efficient and environmentally friendly heating solutions, like those that utilise heat-pumps.

However, it has been widely and wrongly assumed by many in the construction and H&V industry that the low flow temperature associated with heat pumps has generally meant that they have to be used in conjunction with either under floor heating, or oversized and bulky radiators.

When refurbishing an existing property, the installation of underfloor heating is often an impractical solution. There can be high levels of disruption as floors are taken up, and sometimes the substrate needs to be re-laid to install the system.

HVAC emerge – which may cause delays to the project or cause costs to spiral.

The alternative of a space-consuming bulky radiator is decidedly unappealing to today’s customers, who want their radiators attractive, elegant compact and fast-responding.

Dynamic Boost Effect radiators can now help in the fight against climate change whilst looking good

Compact efficiency

exchanger inside a Jaga radiator has been proven in testing undertaken by the Building Research Establishment (BRE) to provide energy savings of 10% a year, which ultimately translates into lower annual fuel bills. A Low-H20 radiator will adapt to any changes in room temperature which means you can gain maximum benefit from free heat sources in the home such as the sun shining through the window or the heat energy produced from your household appliances. It also means eco-friendly heating – a home that has been installed with Low-H20 radiators can emit as much as a ton less CO2 each year.

Finally let’s remember too that fanassisted radiators aren’t just ideal for low temperature systems in refurbishment projects. They are equally suitable for use as part of energy-efficient heating

systems in new build projects, as can be seen from recent projects such as the acclaimed new Department of Environment, Food and Agriculture (DEFA) building on the Isle of Man which achieved a BREEAM Excellent rating.

■

Innovations in heating technology such as Jaga’s Low-H20 and Dynamic Boost Effect (DBE) mean radiators can now help in the fight against climate change whilst looking good. A fan-assisted DBE product significantly boosts heat output levels, which allows for harmonious working with any heat pump technology – be it water, air or ground source. This technological advancement has paved the way for beautifully-designed, compact radiators to be used with heat pumps, offering high levels of sustainability and significant energy savings.

However the benefits of a DBE product don’t stop at their compatibility with heat pumps. The combination of low thermal mass and powerful boosted output means that a DBE product delivers the required room temperature up to nine times faster than a standard radiator. DBE radiators are also fitted with intelligent sensors to constantly measure room temperature, so if the temperature drops below the programmed limit, the integrated microprocessor immediately sends a signal to the DBE units which silently increase the heat emission. Once the desired temperature is approaching, the DBE units then reduce output to achieve the perfect temperature – without energy-wasting overheating.

In refurbishment projects, the marriage of DBE and heat pump technology provides the perfect solution from both the installer and building occupier’s point of view. In fact, the recently published new Domestic Heat Emitter design guide, which forms part of the MCS Installation Standards for heat pumps, is conclusive on the matter. Developed by the Heat Pump association, this guide is endorsed by the Department of Energy and Climate Change and The Energy Saving Trust, and clearly illustrates that fan-assisted radiators are suitable for a much wider range of applications than underfloor heating or conventional radiators.

Renewable Energy

Taking a long term view

■

There are plenty of savings to be had by being more openminded when planning construction projects

Businesses seeking to save money should use this as the decisive driver when in the early design stages of a construction project.

At the GML offices in Coxheath, we advocate a green energy ethos and have installed our own 50kW peak PV solar array, which is saving 75% (£7500 a year) on our overall electricity bill.We also have a solar thermal system in place linked to a ground source heat pump, meaning no need for a gas supply anymore.

As part of long-term design strategies, we actively encourage businesses to buy in to renewable energy solutions as an ‘invest to save’ option.This requires businesses to invest initially with a view to securing a strong return on investment, allowing thousands of pounds to be saved over the years. Government incentives should also be acknowledged as a long-term benefit.

There are plenty of savings to be had by being more open-minded when planning construction projects and preparing scope for an energy strategy. But the net gain is also fundamental for the environment and the whole community.

www.gmlgroup.co.uk

It is important to think about renewable energy in the initial design stages of a construction project rather than it being an afterthought, explains Trevor Barnes, Contracts Director at GML Construction.

W

hen starting a project it is vital to think green and identify areas where renewable energy systems could be installed. By forming an energy strategy early, the cost benefits – both in terms of money saved and global environmental benefits – can be assessed.

Some of the renewable energy solutions available to businesses include: photovoltaic (PV) solar panels; solar thermal; biomass boilers, space heating and hot water from wood chip fuel; ground source heat pumps; and wind turbines, allowing buildings to use electricity generated from wind.

Having green credentials associated with a building is viewed positively by planners and can support the overall planning application process. Experience tells us that if renewable solutions are not incorporated into the original design specification there is a risk they will be omitted due to space or budget constraints. So it is essential, in the short

36

term, to consider these solutions as part of the wider energy design strategy.

Thinking about green initiatives has become a key part of business thinking due to steadily rising energy costs.

Therefore a long-term view on alternative energy is essential.Those that pledge to be environmentally friendly now will be leading the way for others in future years.

Building Information Modelling

Who should take the lead?

As the pressure to adopt Building Information Modelling (BIM) increases, a collaborative approach to construction is essential in order to carry out a successful project. As the first in a series of forum-based articles, FC&A asks a number of BIM experts who they think should take the lead when its come to delivering and managing a BIM-tendered project.

Asta Developments Paul Bamford, MD

Project managers could find themselves in an ideal position to take a lead role as BIM evolves due to their expertise with planning and scheduling.This will become integral to every stage as it can unify information that makes sense of the flow of activities through the whole chain.While the traditional preserve of the project manager has been mainly in the construction phase, the ability to look upstream and downstream with an expert eye on scheduling, key stages, and the marshalling of resources in the right timeframes (especially if supported by tools which create a clear view of the wider process) could open up a range of new opportunities to deliver value. Project managers may find that they can create a new position of authority, supporting not only a single phase but also multiple phases of the construction process.

38

BSRIA John Sands, Principle Consultant at Sustainable Buildings Group A successful BIM project will depend, amongst other things, on clear leadership and the adoption of ‘standard’ procedures by all those involved throughout the life of the project. Part of these procedures is to identify and define key roles and responsibilities, and Building Information Management – A Standard Framework and Guide to BS1192 details many such roles, including the lead designer. This is redefined in PAS 1192-2, just back from public consultation, as being ‘…responsible for the coordinated delivery of all design information. On small- and mediumsize projects, this could be the same as the Project Delivery Manager’. This latter role is described in the PAS as the ‘…keystone for timely delivery and the output at each of the information exchanges and key decision points’. This would seem a good place to start, and would ensure a single point of control for the management of the BIM process and model.

Exactal Software Simon Lovegrove, Director BIM is transitional therefore the leadership role will evolve over time. Currently, higher levels of BIM maturity lie within the design professions resulting in a design lead approach. The key requirement is for organisational and change management initiatives to create the environment to support BIM workflows. Client demand and government intervention, rather than industry consensus, will be central to this. Moving forward, the issue becomes one of information management and development of a specialist BIM or Model Management discipline. As software develops, both inherently and through application of Lean and other techniques, the industry will move to BAM – modelling the building as an assembly of manufactured parts. Assembly processes will dictate product design and component sourcing. Supply chain linkages will shorten dramatically, new supply methodologies will emerge, and the industry will undergo profound structural changes.

Building Information Modelling BIM Technologies Rob Charlton, Chief Executive At BIM Technologies we are not precious as to who is the leader. Our only stipulation would be whoever is the leader understands the requirements of the role.

Traditionally a project has had a lead consultant and this role in the majority of cases falls on the architect.

From experience, architects have considerable complexity to embrace on a project at the early stages and sometimes do not have the time to focus on coordination. In practice what happens is the main contractor picks up some of this coordination via their design manager or on site during construction.

Building Information Modelling identifies this lack of coordination early and encourages the removal of clashes early in the design process.

At present the profession which has the best overall understanding of the complete building is the architect. In the current structure of the industry it is the architect who has the best overview of the design process and who would be best placed as the design coordinator. This may change in the future if there is ever a separate BIM coordinator profession. We do not believe the BIM coordinator replaces the role of the lead consultant but is able to use tools that assist in the coordination part of the role.

Birmingham School of the Built Environment Prof. David Boyd, Director of Centre for Environment and Society Research The real economic benefits from BIM are in building production and, ultimately, building operation. Thus, the lead for the development of BIM needs to come from building contractors using BIM to take more authority of the overall design and construction process. This will involve early involvement in the design in order to maximise its value economically and aesthetically but also a more integrated supply chain to better manage the risks and uncertainties of delivery.

Currently, the implementation of BIM emphasises design and its associated software too much. This is at the expense of an understanding of effective production both its planning and site implementation. To realise these benefits, clients need to understand what BIM can do for them so that they demand changed practices of procurement so that design and construction can be integrated better through the use of BIM.

Asite Nathan Doughty, Chief Operating Officer The way I see it, the path to success in BIM is through collaborative working. Collaborative BIM is just as much about revolutionising supply chain management and procurement practice as it is about technological innovation. One of the key lessons learned from the last 15 years implementing collaborative solutions in UK AEC is that leadership from an engaged client is fundamental to success. The same applies to BIM. The right starting point is for the client to quantify their own business benefit to operations and FM from receiving BIM outputs. Then they need to set clear direction on the deliverables they want to see from the design and delivery processes, and work with their professional advisers to bake these into their forms of contract. Combine this with long-term partnering in procurement practices and we will be that much closer to true collaborative BIM.

NBS Stephen Hamil, Head of BIM

For public sector projects, the UK Government should and is taking the lead.

Through its spending power and wellconsidered construction strategy, it is doing exactly the right thing. By mandating BIM, the UK Government aims to make a 20% financial cost saving and greatly reduced environmental impact within the construction industry. By mandating an open standard, structured data format at specific points throughout the construction phase, the whole supply chain has a very clear set of requirements.This will not only ensure better value for money for the UK tax payer, but it will continue to stimulate innovation and competition within the whole construction industry.

One problem that may arise from a central driver is the risk that small businesses are left behind. However, by ensuring that the requirements can be fulfilled in open standard data formats, expensive proprietary software or complex training programmes should not be necessary.

Concrete Waterproofing

Low risk concrete solutions Concrete is an excellent building material.

It is strong, versatile, inexpensive and available just about everywhere. Concrete is used to build structures ranging in scale from patio stones to hydroelectric dams.

When concrete does deteriorate though, it is generally due to the penetration of water.

42

the opportunity for poor workmanship is high. Membranes require a clean and dry surface, which must also be smooth and even.The membrane must be carefully wrapped around corners and protrusions and pipes and other penetrations require skilful cutting and lapping. Opportunity for failure, risk of high cost repair and liability for the contractor are all unacceptably high.

Crystalline technology is an alternative, and for new build concrete structures, a crystalline admixture is ideal.The admixture comprises chemical compounds that react with available water and partially reacted cement particles within the concrete, and generate the growth of long, prism shaped crystals inside the capillary pores, cracks and joints of the concrete.

These crystals block the passage of water, and as micro-structures they are comparatively rigid and strong – thus they will withstand extreme hydrostatic

pressure and ensure the concrete is entirely waterproof.

Man-hours, the need for specialist skill, risk of failure, liability and whole-life cost are all minimised, and long term effectiveness remains perfect as the compound lies dormant indefinitely within the concrete.

If a new crack should form in the concrete and water begin to penetrate, the chemicals will react to form new crystals at the leaking location and grow to shut off the flow of water – the concrete has the ability to self-repair cracks of up to 0.5mm.

The result is no liability issues, and no distraction from the other demands of the project. Repair and maintenance costs are minimised, and the project manager has peace of mind – the structure they have built is 100% waterproof, and always will be.

■

T

here are several systems out there that set out to eliminate this water penetration, and among the most effective, efficient and maintenance free is crystalline technology.

Sheet membrane products continue to hold a majority market share in the UK though, and despite several advancements in material and application methods over the last 30 years, a membrane still provides insecure protection.

Such systems can be compromised by a single puncture or tear, and carelessness during backfilling and compacting can damage the sheeting; strict schedules and cost restrictions mean such damage will often go unreported and unrepaired.Water entering behind the membrane will lead to loss of adhesion and potential failure at the seams.They also add an unnecessary process to a build schedule.

Installation can also be challenging and

The first and natural choice

Timber fenestration has progressed from the post-war period to present day where it now meets high standards of performance, achieving essential eco credentials and reallife cost savings in energy, carbon and CO2 emissions.

W

hile most manufacturers have been developing new products and systems to achieve ultimate goals of energy efficiency, leading brands within The Performance Window Group (PWG) – Mumford & Wood, Clearwood UK, Dale Windows, Timber Windows and The English Glasshouse – have been at the forefront of this development and have set a benchmark in timber window design and manufacture. Achieving high performance windows that will look good for years to come requires the use of premier grade materials; here engineered timber takes centre stage.

This timber is taken from the heart of the tree where the real strength lies. In

46

■

Engineered timber provides strength, durability and stability and ensures that engineered timber windows will not warp, stick or twist

into three, four and six part lamels.

PWG’s double glazed and factoryfinished windows and doors are energy rated ‘A – C’ and can achieve a whole frame U-value of as low as 0.85 W/m²K, depending on specification.

As a greater proportion of windows made by the PWG companies are larger than a standard unit, there is more capacity to achieve the comfort of an equivalent ‘A’ rated window which reduces energy loss to zero.

House building methods have also improved and factory-finished windows installed into prepared openings and fitted behind a reveal rather than forward in the opening will make considerable impact on the performance of the window and can account for an improvement of as much as one rating point. It is these eco points that stack up in the BRE Green Guide assessment in the Code for Sustainable Homes scoring criteria in order to meet the controls for reducing carbon footprint.

An ‘A’ rated window scores maximum eco credits equal to Level 6 Zero Carbon – the ultimate goal.

quite a short time – weeks not months – it will start to curve and twist unless treated and kept in perfectly humidified conditions.

The heart wood is scanned for defects early in the process, a computerised action, identifying resin pockets and knots which are cut out. The clear parts are then finger jointed and glued in six metre lengths to create top quality, clear grade timber.

Improved stability Independent tests have proven that an engineered component is 60% stronger than a piece of solid wood in the same section size which ensures stability and overcomes the risk of mis-shape. These components are purchased direct from European suppliers and specified in grain direction for each and every component size. This significantly improves stability, visual appearance and the performance of the paint finish as paint will not adhere well to over-dry wood.

Mumford & Wood uses larch in its standard specification. It grows very slowly and typically produces timber that has tight growth rings and is darker in colour than sap wood. The logs are converted into vertical grain scantlings, finger jointed then laminated

Roofing, Cladding & Insulation Architects and designers can now create large areas of daylighting, which can be as energy efficient as an insulated solid wall

New light on old problems Architect Christopher Sykes discusses how modern daylighting technology is transforming aged buildings.

T

he UK building industry has suffered an enormous shock as a result of the recession. The days of ever increasing growth and full orders books have gone. At the same time the industry has also experienced a vast sea change. The nature and source of projects may be different but, at the same time, there have come opportunities and the biggest of them all is refurbishment and retrofit. Clients are now focusing their attention on the potential of existing facilities, schools, leisure centres and the like, exploring how these can be improved and transformed.

Unique diffused daylighting system is enjoying a resurgence in the transformation of buildings

48

At the same time, new thinking has opened up new territory for some building products and systems, particularly those which already have a strong foothold in newbuild and offer green benefits, such as energy-saving and insulation, and which have not yet been fully recognised for their refurbishment potential.

A major advance is in the field of daylighting technology and one good example is how Kalwall is providing new solutions to old problems. This unique diffused daylighting system is enjoying a resurgence in the transformation of buildings which have reached critical stages because their structure and their glazing have failed and stringent new Building Regulations make normal patching up impossible.

Eccleshill local authority swimming pool near Bradford is a good example.

Built in the 1960s, the original design was a steel-framed curtain wall with plywood cladding panels.

The solution for the steel frame, which was corroding and had become structurally unsound, was to demolish the flank wall and install a translucent system.

Rebuilding with Kalwall has introduced

diffused natural daylight into the pool, greatly improving the interior ambience.

Running costs have been reduced because of the improved insulation and there is less reliance on artificial light, while overheating on sunny days has been eliminated.Visitors can now swim in a private and safe environment because there is less glare on the water, making it easier for the lifeguards to see a swimmer in distress. Other examples, include a wide range of quite different projects from healthcare and industrial to education and public transport hubs.

It is also important to mention new technology which has revolutionized the insulation performance of translucent systems. This is Lumira aerogel based on the world’s lightest and best insulating solid which dramatically increases thermal insulation with U values as low as 0.28W/m2K. Used within the Kalwall translucent cladding and rooflighting system, its addition means that architects and designers can now create large areas of daylighting, which can be as energy efficient as an insulated solid wall.

Roofing, Cladding & Insulation

SkanDek offers built-in safety with edge protection Safety during construction has to be a paramount consideration when a designer is specifying roof construction. Within the Work at Height Regulations 2005 and Regulation 13 of the CDM regulations there are clearly stated requirements to consider working at height issues from the very inception of a project.

When a SkanDek structural roof element solution is chosen, the designer and contractor have the option to use its special pre-installed edge protection.

SkanDek roof elements can be

Leading engineered timber manufacturer James Jones & Sons,Timber Systems Division, has designed its first fully EC5 compliant roof for a school in Scunthorpe.

This large scale project, which used 2,400 lm of the company’s UK manufactured, FSC, JJI-Joists, was designed in-house using specially developed software.While the actual roof design was fairly standard, with a single ridge and a fall to either side, a solid timber overhang and openings to accommodate windows and automatically opening vents, its sheer scale was significant.This had implications for both the manufacture and supply of the roof, which was carried out by James Jones’ distribution partners, Boards Cottingham.

delivered to site with sockets pre-installed to take posts to support the required rails and toe boards. The ends and sides of

the element have the patented SkanDek steel beam that provides a strong fix for the sockets that are sacrificial and will be hidden by the roof finish.

This edge protection can be installed on the ground just prior to lifting and fixing the element. For many applications a method statement can be followed that will not require netting.

The SkanDek roof system with light, high strength prefabricated elements optimises construction allowing a fast, no-waste and low risk build and now with its special pre-installed edge protection offers safer working with potential cost savings.

A. Proctor Group recently supplied its Profloor Levelling System to Countryside Properties’ recent development of 300 flats at St Paul’s Way, London.

The Profloor Levelling System was developed in order that a level, finished floor could be laid on a cambered, stepped or uneven sub-floor. The Levelling System is used on typical structural concrete floors where differences in level are too great for a finished floor. The floor is levelled by inserting packers in each Levelling Base to adjust the level of the timber battens and thus create a level finished floor, wet trades being completely eliminated. Ideal for new build flats and conversions to flats where impact and airborne sound reduction is mandatory. ask@proctorgroup.com

Doors, Windows & Balustrades Victory Pier is a Berkeley First project on the river Medway in Kent. Described as offering the opportunity for residents to enjoy London-style riverside living in Kent, it is a striking new waterside village development of apartments and penthouses.

The luxurious nature of the development means that the contractors were looking for something special at every stage of the specification process, not least when it came to the windows.The contractors were looking for a coloured profile that offered long-lasting, non-fading good looks and excellent energy efficiency.The choice of supplier was also paramount – the manufacturer would need to have extensive experience of working on large-scale, high profile projects.

Dempsey Dyer offered both the product and the experience that the contractors were looking for and were successful in the tendering process.

Dempsey Dyer tendered for the project

Dempsey Dyer’s winning combination using the Deceuninck 3000 Series range coloured in RAL 7031 Blue/Grey using Deceuninck patented Decoroc process.

One thing about the Decoroc structure that the contractors were particularly impressed by was the colour fast guarantee – having seen other coloured profiles used on other projects fail, this consideration was an important one.

Aluminium windows have long been specifiers’ window of choice, especially on design-driven projects such as Victory Pier.

But the Deceuninck Decoroc coloured profiles demonstrate that PVCu can now more than give aluminium a run for its money Coupled with Dempsey Dyer’s expertise, experience and commitment, it was a winning combination for Berkeley Homes.

Now it is even easier to make deep cuts at a low cost thanks to the launch of Husqvarna’s power cutter with the Cut-n-Break function – a unique method for making deep cuts in concrete.

W

ith a more powerful engine, better ergonomics and reduced emissions, the K 760 Cut-n-Break has all the requirements to be a hit with cutting and drilling contractors.

It is a versatile all-round machine for

cutting and drilling contractors who sometimes need to make deep cuts.

Husqvarna’s new power cutter can handle cuts of up to 400 mm, with a lower tool cost than a diamond chain saw. The K 760 Cut-n-Break is the follow-up on the popular K 650 Cut-nBreak, Husqvarna’s first machine with the revolutionary technique.

The technique and performance are significantly enhanced with the new cutter. The biggest innovation is an entirely new engine body – the K 760 Cut-n-Break is equipped with Husqvarna’s low emission X-Torq engine which makes the machine more powerful

Husqvarna launches K 760 deep cutter

while being better on the environment at the same time.

More power, 3.7kW, means that the blade cuts through the concrete with more resilience and consistency. An improved ergonomic design is noticeable, among other things, in the form of a more robust front handle, making the grip more comfortable. An effective vibration dampening system and sounddamping makes the machine more comfortable to use.

The K 760 Cut-n-Break diamond blades boast a new construction too, with a higher strength, which means they are more resistant to thermal strain.

The double, specially developed 230mm blades grant higher cutting speed and power. The areas of application for the K 760 Cut-n-Break are window, door, and ventilation openings where overcutting is to be avoided, grooves for cabling and crack renovation.

Aico’s RadioLINK ensures safety and reliability Providing vital fire detection for domestic residents, Aico’s RadioLINK is consistently building on the success of the market’s first Radio Frequency wireless alarm system.

Aico broke new ground when it launched RadioLINK in 2004 as the very first wireless alarm interconnect system in the domestic field. Today, RadioLINK is the market leader, successfully operating in

thousands of private properties and social housing throughout the UK. Interconnecting smoke alarms in a domestic property is a requirement of BS 5839: Pt.6: 2004 and Building

Regulations. It provides an earlier warning for residents and the best chance of escape.

However, hard wired interconnection is time consuming, disruptive and costly. RadioLINK, on the other hand, works by allowing mains powered smoke, heat and multi sensor alarms to be wirelessly interconnected by Radio Frequency (RF) signals. If one alarm on the system is triggered, radio frequency signals are used to cause every other alarm in the property to sound.

It has made mains powered alarms quicker and cheaper to install, made interconnection itself more popular and also makes it far simpler to make changes to a system to help meet the changing needs of different residents.

RadioLINK provides highly effective fire detection with a number of unique features, including its ease of installation and set up and its ability to wirelessly interconnect to other devices for maximum effectiveness and flexibility. enquiries@aico.co.uk

High efficiency ventilation

Johnson & Starley’s new Q-Vent HRC 8x3 system provides mechanical ventilation to en-suite bedrooms and features high efficiency EC fan technology. Heat is recovered from the stale contaminated air drawn from the bathroom and a high performance heat exchanger recovers the heat and transfers it to temper the incoming fresh air.The ventilation rate will increase when the bathroom is being used for periods in excess of two minutes and the unit switches to boost mode.The extracted air is then discharged to the outside via a single duct and grille. Available in top or bottom opening versions, the case of Q-Vent HRC 8x3 is constructed from aluminium/zinc coated steel.

Over 100 people attended the grand opening of Windhager UK’s prestigious new headquarters in Marshfield, Gloucestershire, which boasts the largest dedicated biomass training centre in the UK. On opening the new company premises, Windhager UK managing director Oliver Duckworth said: “The renewable industry has bucked the current economic trend and our growth over the seven years since we started the company has enabled us to make this significant investment in new facilities and training centre.” He continued: “We are firmly of the belief that quality training of installers will drive the future growth of the biomass market.” Windhager UK is an approved HETAS training centre complete with a line-up of fully functional models from the Windhager biomass range featuring LogWIN, the split log boiler, plus all the wood pellet boilers available namely BioWIN,VarioWIN and FireWIN. The company’s hot water accumulator AccuWIN, its pellet hoppers and suction systems as well as its solar thermal range and controls are also in operation in the training centre.

Paints, Coatings & Finishes

Ultimate new build coatings Crown Trade has developed a range of coatings specially formulated for use in new build properties, delivering the best paint for the job in these environments.

and housing developers alike.

The combination of New Build Acrylic Primer Undercoat followed by two coats of New Build Acrylic Gloss delivers an exceptionally durable high gloss finish that retains its sheen level for years.

Another choice is Crown Trade Acrylic Satin, launched as an alternative to New Build Acrylic Gloss, for customers who prefer a satin finish.

Crown Trade New Build Acrylic Gloss and Acrylic Satin Finish both have less odour than traditional gloss and there’s a much lower risk of sagging.They are quick drying, so a three-coat system can be completed rapidly, and all equipment can be cleaned up in water. Both systems can be used throughout a property, indoors and out and can be applied at temperatures as low as 5oc. A video explaining Crown Trade New Build Acrylic Systems can be viewed online at www.youtube.com/crowntradetv Also new from Crown Trade is its Covermatt Drywall Primer.This versatile ready to use primer has been specially developed to give contractors working on new build sites more control over the wall.

Applying just a single coat to walls and

ceilings by brush, good quality medium pile roller or spray will even out all the differences in texture and absorbency and make it much easier to achieve uniformity across the panels and joints. The primed surfaces can then be given their first decorative coat in just four hours.

A high opacity, dead flat matt coating – and an ideal first decoration product to use with Crown Trade Covermatt Drywall Primer – Covermatt Obliterating Emulsion can be used all the way through a newly-built property, applied by roller, brush or spray.

Due to the fact it is moisture vapour permeable it can even be applied to new substrates, which have not completely dried out. They can be left to dry naturally without fear of the finish cracking or peeling.

T

he very latest new coating system targeted at this sector is Crown Trade New Build Acrylic Gloss and New Build Acrylic Primer Undercoat, introduced in direct response to concerns voiced in the new build market about accelerated ‘yellowing’ problems associated with ‘2010 VOC compliant’ alkyd-based gloss systems on the market.

Alkyd-based gloss is popular because of its very high gloss finish and ease of application. The technology does however have a downside. In order to facilitate proper drying, chemicals have to be added to the formulation. The curing process continues after the paint film is dry and as part of that process, over time, all alkyd paints ‘yellow’. In order to reduce solvent levels sufficiently to comply with recent VOC legislation, higher solids resins have been used which can result in accelerated yellowing in some circumstances as they cure.

Crown Trade’s New Build Acrylic Gloss system is a high performance alternative to alkyd-based gloss, which eliminates yellowing completely and offers additional benefits for contractors
