Specifiers, by their nature, love to shop. The trouble is that, over the past five years or so, they鈥檝e become increasingly uncertain what they ought to be buying. The sustainability agenda has unleashed a vast number of products onto the market, but it takes a seriously dedicated shopper to travel to all the manufacturers in the UK and abroad to work out which ones they should be splashing their cash on.

Now materials giant Wolseley thinks it has an answer. In deepest Leamington Spa, it has built the Sustainable 好色先生TV Center (SBC), using many of its own range of 7,000 eco products. Part Ikea showroom, part exemplar building, the idea is that specifiers can see the products in action and get all the information they need with one port of call.

Even though it doesn鈥檛 open until next month, the centre has caused something of a stir in construction circles, and many of the industry鈥檚 biggest spenders have already visited. So we decided get an impartial view by sending along an architect with a no-nonsense approach to assessing products. As technical director of Scott Brownrigg, Peter Caplehorn spends much of his working week looking into new products, understanding how they work and analysing the manufacturers鈥� claims. Only when he鈥檚 satisfied will he specify them on his own projects. So if the SBC is just an elaborate sales pitch, he鈥檒l soon find out.

The concept

Caplehorn certainly seems impressed by the idea behind the centre. 鈥淲henever I鈥檓 looking at products I might specify I like to go and look at them in use,鈥� he says, 鈥渨hich usually means travelling around to several sites or even going abroad.鈥�

Tim Pollard, Wolseley鈥檚 head of sustainability, is showing us around. Caplehorn asks what the criteria were for the products they offer. 鈥淎 lot of the products existed, but they were on the fringes of the construction industry,鈥� says Pollard. 鈥淚f the environment was to become a big issue it required mainstreaming so that major housebuilders, developers, and public clients could access them in commercial timescales and in commercial quantities and prices.鈥�

Caplehorn stresses the importance of having complete confidence in the products and manufacturers that he chooses. Pollard says that this is integral to the concept. Wolseley has spent the past three years building up the list of products, verifying manufacturers鈥� data, putting in place supply agreements, training staff in its outlets as well as producing a 150-page catalogue and building a dedicated website.

Caplehorn鈥檚 verdict 4/5

鈥淣ormally when I鈥檓 looking at a product I鈥檒l assess it to make sure that it does what it says it will and also check out the track record of the manufacturer and supplier. In a way they have cut out that step. It鈥檚 also very rare that you get the opportunity to compare similar products all on the same site, so from that point of view it鈥檚 fantastically powerful.鈥�

Presentation

The tour starts off on the ground floor. Caplehorn is interested to know what the architectural goals were when project architect ECD was given the brief. 鈥淭hey made it clear that the centre should not look like an industrial or commercial building,鈥� says ECD鈥檚 Mark Elton, who鈥檚 also joined us. 鈥淎t the time we didn鈥檛 know what products would be going into it.鈥�

鈥淚t would have been easy to come up with a building that just looked like a sample board of products and materials,鈥� says Caplehorn, with his architect鈥檚 hat on.

Visitors enter through some weighty double doors into a full-height, glazed 鈥渟treet鈥�. This is the buffer zone between the heavyweight building on the right, housing the main display areas, and the lightweight structure on the left which includes a lecture theatre, offices and a cafe. 鈥淚t shows people the sort of approaches they can take,鈥� says Elton.

Caplehorn asks about energy monitoring. Pollard explains that a full energy management system has been installed to show visitors how the equipment and the various areas of the building perform.

Everything that can be seen at the SBC can be bought, from the fired clay blocks and Thermowood cladding to the LED uplighters, guttering and downpipes.

More fringe materials, such as earth-rammed or straw-bale walls weren鈥檛 used for the simple reason that Wolseley doesn鈥檛 sell them, says Elton.

Cutaways reveal the three types of insulation used and the underfloor heating system. Caplehorn seems pleased that so many systems and structures are left exposed. 鈥淵ou get a lot of people who want underfloor heating and there are one or two things they don鈥檛 get: one is that the floor will get hot and the other is you鈥檒l have a huge load of pipes coming up through the floor which you have to co-ordinate and which must go somewhere. If they see this they鈥檒l be able to understand it.鈥�

Nothing in the building is just for show. The three heating sources 鈥� a combi boiler, biomass boiler and ground-source heat pump are all fully functional, as are the two solar thermal systems and PV arrays.

Caplehorn鈥檚 verdict 4/5

鈥淚t would have been easy to create a patchwork building with no integrity, or something that included the bells and whistles but has no real focus. As it is they have achieved a good balance. The building has a nice character, which introduces you in a gentle manner to the technologies that are available. It鈥檚 also a functional building, a good place for demos and a good focus for people to talk about sustainability.鈥�

Range of products

The SBC offers customers a sustainable alternative for every stage of construction, which was the reason the products were chosen. This covers everything from substructure and wall construction to heating and ventilation and renewables.

Technologies on show in the centre will be updated as products come to market. Already there are plans for a domestic air-source heat pump.

What about micro wind turbines, asks Caplehorn 鈥� these don鈥檛 appear in Wolseley鈥檚 catalogue. Pollard and Elton don鈥檛 think they are a worthwhile investment but are still going ahead with one. 鈥淲e鈥檙e going through the planning rigmarole at the moment,鈥� says Elton. 鈥淎t least when if one is installed people will be able to see for themselves the performance characteristics.鈥�

Caplehorn鈥檚 verdict 3+1/2 / 5

鈥淚鈥檝e not seen any new technologies, but I have seen a few things that I had only read about, and ranges I didn鈥檛 know certain manufacturers did. They鈥檝e concentrated on the territory of proven technologies, which fits with their strategy of only showcasing the ones that are commercially available. However, in terms of inspiring a designer the range is slightly limiting.鈥�

Information

A visit to the SBC includes a guided tour and time to explore on your own. Every trip starts with a questionnaire asking what you鈥檙e interested in 鈥� if there are specific areas of interest the display area will be set up with extra information and samples to reflect this.

On arrival everyone is given a PIN which can be used at the information hubs dotted around the centre. By punching in their PIN into a touchscreen visitors can request more detailed installation and operational data on any of the products. These are emailed to them after the visit. 鈥淥ne of my big bugbears is that people are always trying to give you literature, which is hardly sustainable. What you really want is the information in electronic format,鈥� says Caplehorn.

Also scattered around the centre are 21 small video screens mounted on stands, which give information on the products nearby and short videos of the installation.

Caplehorn鈥檚 verdict 4/5

鈥淚鈥檓 not sure if the video screens really get the message across. They were quite small and I鈥檓 not sure whether they can hold people鈥檚 attention.

鈥淭he information hubs are a really good idea 鈥� although they did seem a bit tricky to use.鈥�
