Story

Following the decision by Wolseley UK and its appointed Consulting Engineer, Fulcrum Consulting, to specify Hepworth Building Products’ SuperSleve drainage system, Hepworth was asked to advise the sub-contractor on ways of improving the sustainability of the project on site.

Application
The site investigation report identified that the lower level sub-soils at the Sustainable Building Center were of a sandy nature and did not contain any large stones. Hepworth confirmed that the sub-soil would provide a supply of low cost pipe bedding and surround material. Unfortunately, insufficient quantities were being excavated on site to be used throughout the project and therefore Hepworth suggested that a local supply of recycled aggregate be selected as the next most sustainable option. These principles made the development more sustainable by preserving primary aggregate resources and reducing costs, without compromising the build quality of the development.

Testimonials
Allan Homewood of Fulcrum Consulting (a company member of the UK Green Building Council) said “Our approach to sustainability is the application of an integrated engineering design to buildings and infrastructure to provide the optimum solution for each of our clients' particular needs”. Allan continues “we have known for some time that SuperSleve clay pipes themselves provide a sustainable installation and was an obvious choice for this project, as it embraced the client's ideal of a sustainable building. But in addition to this, it is also sustainable in installation as recent research has demonstrated that suitable recycled construction demolition material can be used as a replacement pipe bedding and surround material. This reduces the need to import primary aggregates, thus reducing the overall amount of embodied energy in the building.” On the use of recycled aggregate, Lou O’Malley from Flair Build said: “Hepworth was very involved with this project from the start and spent a lot of time advising us how to implement a sustainable drainage system. The technique that really impressed us was the use of recycled aggregate. Not only did this process save money, it also reduced installation time with less bedding required. Hepworth’s advice helped us to be more efficient and environmentally aware. We will definitely use the techniques, including the use of recycled aggregate where possible, in the future”.

Conclusion
Paul Wydell, Product Manager at Hepworth Building Products said: “If more developers thought about sustainability in this way we would all be in a greater position to support good environmental practices.” He adds: “This project proved that if you assess the site before construction starts you can reduce its carbon footprint further and reduce cost without reducing quality.”

The water delivery system for highly innovative ‘pre-wash’ stations being installed in the entry and exit corridors that athletes will use leading to and from the Beijing Olympic swimming pools has been designed by Cheltenham based Rada Controls, the commercial division of Kohler Mira.

The stations are a triumph for global inter company co-operation as the exterior elements are fronted with Kohler Water Tiles which create an invigorating 22 nozzle body spray. But behind the scenes it is Rada equipment that will consistently deliver the water through the nine tile banks that are ceiling mounted.

The spectacular $100 million ‘Water Cube’ which houses the Beijing National Swimming Centre for the XXIX Olympiad bristles with innovation. It has two full Olympic size pools, a diving pool, leisure water features and can seat 17,000 spectators. It has been designed for year around use by the residents of Beijing once the Olympics are completed.

The centre is designed by Australian architects and it was the style and quality of the Kohler Water Tiles that they felt complemented the pools overall design and quality. Having approached the Kohler China sales team to supply the tiles, they in turn contacted Group sister company Rada in Cheltenham UK to create a water delivery system that is consistent and fully automated.

Rada specified its Rada Pulse multiple outlet infra red control system with ceiling mounted sensors that activate the water supply to the panels. Each pre-wash station is served by 2 Rada 222-T3 thermostatic mixing valves which are fully TMV3 compliant.

The Rada 222-T3 is well proven, wholly reliable and offers safe, accurate temperature control under varying supply conditions, which will prove invaluable to the contractors in Beijing where, in a complex so large, maintaining constant water pressures is likely to prove a challenge.

On the installation, Roy Minett, Rada’s commercial manager comments; “to be associated which such a prestigious project is a great honour for Rada. We specialise in all aspects of commercial washroom activity and our design expertise and product range reflects that.

“As such, when we received the initial enquiry from our colleagues in Kohler China, we were able to respond with a constructive proposal. Our design theories were proven in our test facilities in Cheltenham before shipping the units to Beijing where they were successfully installed at the end of January this year.”

In total there are 10 water stations servicing the two Olympic pools in the Centre, each with nine Kohler Water Tiles, two Rada 222-T3 TMV’s and a Rada Pulse installation on each.

Environmental award-winning building products manufacturer, Hambleside Danelaw, has been presented with a Plan Vivo certificate in recognition of the carbon offset payments that it has made into a plantation and forestry project for farmers in south-west Uganda.

Carbon offset is an important, but only one, aspect of a comprehensive environment strategy operated by Hambleside Danelaw which involves the careful design and selection of raw materials for its energy-efficient products to ensure an extended service life, coupled with the recycling of production waste. Landfill waste is expected to be no more than 3 tonnes by the end of 2008, having stood at 900 tonnes per annum in 2001.

Hambleside’s Plan Vivo certificate resulted from its offsetting of 1,217 tonnes of CO2 last year. A payment by the Group through the BR&D Plan Vivo scheme contributed to an Ecotrust project in the Bushenyi district of Uganda. The project works with established groups of farmers to plan agroforestry and small scale plantations, helping diversify farm incomes and allow controlled access to fuelwood and building materials. The project has been operating successfully since 2003.

Commenting on the award of the Plan Vivo certificate, Hambleside’s environment manager Ray Khan said: “This certificate is a further symbol of our belief that environmental policies are good for business, improve customer relationships and provide far more reaching socio-economic benefits.

“The Plan Vivo project attracted Hambleside Danelaw because as well as making a contribution to biodiversity conservation, it is reducing poverty and helping to sustain livelihoods through sustainable agriculture and micro-enterprises.”

Hambleside Danelaw is also a member of dcarbon8 which encourages clients and end-users in the commercial property market to choose building materials that will help to achieve a sustainable, economical and responsible method of reducing carbon emissions.

Stertil Stokvis has recently completed a significant distribution centre installation for Multipart Supply Chain Solutions. Multipart has invested £20 million in the 268,000 sq ft site in Chorley, Lancashire and the new centre handles operations for the company's client Lex Auto Logistics.

Multipart Supply Chain Solutions is a specialist in supply chain management, delivering a complete range of linked services from cataloguing and order capture to inventory control and supplier management. It also provides specialist storage, handling and transport, as well as reverse logistics and customer services. The company chose the new Chorley distribution centre to relocate its operation for Lex, which had been situated on a site in a predominately residential area. The new centre relies upon 12 dock leveller loading bays and Stertil was awarded the contract to supply and install them.

Stertil worked alongside Bowmer and Kirkland, the main building contractors, to complete the installation, which will allow around 25 deliveries and 10 despatches to be made from the distribution centre each day. The products Stertil installed included a swing-lip dock leveller, wheel guide, collapsible dock shelter and a Thermadoor insulated sectional overhead door for each loading bay, as well as two level access doors, eight fire exit doors and three RapidRoll 660 doors inside the building.

“We have major strategic plans for the future but were constrained by the limitations of our former site,” explains Deven Thakrar, Multipart's Managing Director. “The relocation of the distribution centre is a big step forward and will enable us to pursue new business opportunities and continue to improve our service to existing clients. It also provides job security for our employees and potential for employment growth.”

Multipart has developed high-value propositions for niche market sectors such as automotive, retail, manufacturing, vending and utilities.

Worcester has added to its growing range of renewable technologies with the introduction of a new collection of Greensource air to water heat pumps, offering homeowners an alternative option for ‘greener’ home heating with minimal CO2 emissions.

The technology inside an air to water heat pump works on similar principles to a domestic fridge. An external fan draws air from outside the building into the unit before converting the latent heat within the air into useable heat for home. Designed to work with existing wet central heating systems, Greensource air to water heat pumps transfer the converted heat into water to deliver low-cost, energy saving heating and hot water all year round.

Worcester’s air to water heat pumps are also the perfect partner for underfloor heating and oversized radiators. Even though the heat pump can operate at up to 65oC flow temperatures it is more efficient when operating on lower temperature heating systems. However, even really cold air can be converted into heat, as the Greensource system is capable of working efficiently in outside temperatures of up to -20oC.

When properly installed, an air to water heat pump can produce up to approximately 4 times more heat energy for use in the home than the electrical energy it consumes. Greensource air to water outdoor units have a COP (Coefficient of Performance) of up to 4, which means each heat pump is capable of providing up to 4 kW of energy for every kW used.

A choice of three outdoor air to water units is available from June 2008 – 6kW, 7kW and 9.5kW. And to complete the package, Worcester has also introduced a Greensource hot water distribution unit for indoors with compact dimensions and a storage capacity of 151 litres.

Martyn Bridges, director of marketing and technical support said: “Air source heat pump technology has become increasingly popular in the Swedish market, so with our comparatively mild winters these products will suit UK requirements perfectly. We think they will catch on quite quickly, as the only space requirement for installing an air to water heat pump is an accessible outside wall. This makes them suitable for a wide range of property types, especially those with open plan spaces.

“We have been working hard to develop and test our Greensource products over recent months to ensure they are absolutely spot-on for the British market. Making them easy to install was also vitally important.

“As would be expected, we are introducing a new training course to support installers keen to start passing on the benefits of this new technology to their customers. Given the feedback we have already had from the trade, we are confident that air source heat pumps will become a very popular alternative to traditional heating systems in the next few years.”

The latest in advanced, sustainable heating and hot water solutions, Worcester’s innovative Greensource air to water heat pump and Integrated Cylinder will be available from June 2008 and are soon to be followed by the introduction of an air to air heat pump this autumn.

All air source heat pumps in the range are covered by a comprehensive 2 year warranty* as reassurance of the built-in quality and reliability for which Worcester, Bosch Group is renowned.
