IntervIew PAtrick Bellew, Atelier ten Patrick Bellew asserts that Atelier Ten aims to lead by example on sustainability 30 Architects have leadership in the design process but building services engineers have thought-leadership reduce mechanical heating and cooling within a building. This means following the process – recognised widely in the industry now – of starting with the creation of a highly insulated, energy efficient building envelope that uses lots of natural light, and then looking at what heating, ventilation and cooling ‘kit’ needs to be installed. This may also mean applying advanced control technology to help deliver the right air movement and heat flow – and to turn off the lights. Bellew’s personal inspiration for pursuing a passive-ventilation approach to building services design – well known to those who have followed his career – is the termite mound, which uses a thermal storage system contained in the ground and an earth tube that brings air into the nest. The nest also uses evaporated water to produce an air-conditioning effect. This natural structure, of course, has its limitations – not least a lack of natural light and poor insulation – but Bellew has used it as a model for the creation of underground concrete labyrinths that ‘integrate subterranean thermal storage into air conditioning pre-heat and pre-cooling systems, to minimise demands on the airhandling plant in the building, providing comfortable conditions with very low energy consumption’. One example of this process in action is the Planet Earth Gallery at the Earth Centre Project in Doncaster, UK. Bellew says that using concrete slabs within buildings – ‘applying their high thermal mass as a friend to maximise night-time cooling’ – together with earth ducts for ventilation, are intuitively low-energy processes that can now be proven to be effective. ‘This is now all underpinned by improved modelling,’ he says. However, clients still expect to see hard evidence of green kit in the form of fan coils and chilled beams, he laments. Atelier Ten is working with two universities to conduct research into nano-materials for buildings, backed by funding from the UK Technology Strategy Board. The aim, says Bellow, is to develop advanced thermalstorage systems that can be applied to larger commercial buildings. This pursuit of innovative technologies to increase the energy efficiency of buildings offers up some hope that the building services industry can achieve the ‘step change’ that Bellew believes is necessary if Britain is to achieve its carbon-cutting targets. But collaborative work among different professionals in the industry supply chain is also crucial. ‘Architects have leadership in the design process but building services engineers have thought-leadership,’ argues Bellew. But will architects be prepared to cede their dominant design role to engineers? ‘Some architects will never be persuaded to change. But most are keen to try to delegate, but they complain that engineers don’t push themselves forward enough to provide the leadership they could offer,’ insists Bellew, who points out that he learnt about architecture as well as engineering as an undergraduate at Bath University. (He is now a Visiting Professor at the School of Architecture at Yale University in the US.) But, decades later, this multidisciplinary approach to undergraduate learning is thin on the academic ground. Bellew suggests that this may be something to do with the building services education sector not wanting to dilute the engineering content of its courses for fear of not being able to attract undergraduates. Does Bellew think that CIBSE is succeeding in taking a lead on raising the status of the building services engineering profession? ‘I don’t sense a huge amount of leadership coming from CIBSE,’ he says, but points out that he’s not directly involved in the institution. He adds: ‘CIBSE could be involved in testing new technologies – for example, jointly with organisations such as the Building Research Establishment.’ Bellew is able to point to several examples of award-winning projects that Atelier Ten has CIBSE Journal April 2011 www.cibsejournal.com Simon Weir
