Rosi Fieldson

An architect at a medium-sized practice in the East Midlands, Rosi Fieldson is part of a small group of consultant practitioners and researchers who set up the Construction Emissions Community of Practice in 2007. The group was formed to drive a grassroots shift among architects and engineers in addressing the problem of carbon emissions from new building. It plans to continue raising awareness of embodied and end-of-life emissions until this becomes a nationally recognised and utilised key performance indicator. Such activities show that it is not necessary to be a big name or to move among the London elite to influence a sea change. Fieldson holds up Hill Holt Wood as an example of the future of architecture, demonstrating a different way of thinking about development and construction. She says: “It may seem like a one woman crusade at times, but I am determined to bring as many people to see that building our best can be profit in itself.”

Philip Hawtin

Philip Hawtin is project architect with Stride Treglown on the Oak Building office development for the Ministry of Defence at Abbeywood in north Bristol. By designing from first principles, the development questions the perceived wisdom of many new sustainable projects. Despite using no biomass, photovoltaic panels, solar water heating, sedum or cedar cladding, the scheme is still rated Outstanding on the DREAM scale (the defence specific version of BREEAM). Focused on reduced energy consumption rather than on-site generation, it uses an insitu concrete frame and masonry cladding to produce a high-mass, slow-response building, but with high insulation values. BMS controlled windows give night purging for cooling, but with manually controlled natural ventilation. Designed for natural light, active brise soleil tracks the sun, reducing thermal gain and removing glare from PC screens. Moreover, life-cycle costing techniques have produced a solution that represents good value for the client, without a long-term maintenance burden.

Jonathan Hines

For 20 years Jonathan Hines has been pushing the boundaries of sustainability in the built environment as director of Architype. A uniquely radical company, many of its innovations were UK firsts, including breathing timber construction, timber I-beams, use of non-treated timber and organic paints, six-storey timber frame, and use of UK-grown timber in construction. Originally dismissed as fringe, many of these have now been adopted by the mainstream. Recognition has come through a series of awards, including Green Building of the Year in 1995, Sustainable Architect of the Year in 2007, RIBA Sustainability Award in 2007 for the design of Architype's own office in Hereford, and most recently Hines became the first architect to win the Ashden Award for Sustainable Energy. He regularly writes on sustainability and speaks at conferences and universities, assists others in developing their approaches and participates in research. He is still at the forefront of sustainability, challenging conventional thinking, regulations and zero-carbon targets, and promoting forward-thinking innovative but practical solutions.

Jes Mainwaring

Jes Mainwaring joined the newborn ECD Architects to execute Futurehome2000 for the BBC Money Programme in 1981, introducing low-energy design to the public. Deeply involved in many ECD projects, developing innovative energy and environmental strategies, he led his team to win Green Building of the Year in 1996 for Linacre College, Oxford, and his scheme at Boxfield Farm, Stevenage, was the first BREEAM rated housing scheme. Mainwaring, who has long believed that sustainable architecture should be a mainstream activity rather than a hair-shirt philosophy, has been among the first to bring green architecture to Portugal, developing the Coolhouse adobe-based sustainable construction system to meet local climatic conditions, including an alternative to air-conditioning shown to reduce comparative carbon emissions by 94%. His work at AlmaVerde has won international awards for sustainable architecture and innovation, including the pan-European Royal Award for Sustainability. He also speaks at sustainable construction conferences and seminars and has contributed to many best practice and design guides, publications and broadcasts.

Arthur Tatchell

Architectural director of NPS South West, which he joined 12 months ago, Arthur Tatchell has been inspirational in leading design teams on numerous projects and drawing recognition for the green agenda. He was actively involved in developing the initial philosophy for Montgomery primary school in Exeter, which aims to be the first zero-carbon-in-use primary school in the UK by utilising Passivhaus methodologies (supported by the Zero Carbon Task Force), and is continuing to inform and direct the efforts of the design team there. He is working alongside Exeter University’s Centre for Energy and the Environment to turn theoretical ideas into practical reality. Not only does his enthusiasm for the project inspire members of the design team, the client and end user, but Tatchell engages with the pupils too and clearly wants to inspire the next generation to tackle the issue of climate change with innovative architecture. He also recently mentored students at Tavistock College to a creditable second place in the national RIBA competition to design a new parliament building to replace the Palace of Westminster.

Sarah Daly

After becoming managing director of Heath Avery Architects last year, former international marketing consultant Sarah Daly launched the firm’s sustainability auditing and consulting services and is now working with a software company to package up the services to reduce the cost of delivery and to sell on to other practices. She is also developing research bids with academics from the universities of Bath and Reading to quantify the benefits of holistic approaches to sustainable auditing, refurbishment and return on sustainable investment, with NHS Gloucestershire as the client collaborator. As well as publishing articles on sustainability and contributing to a sustainability book, Daly gives many free masterclasses, seminars and workshops, including at NHS Innovate 09 and Ecobuild 2010. Besides planning an eco-home for her own family as an example of low-cost green innovation, at the opposite end of the spectrum she is about to launch a major campaign called Green Gloucestershire to create the first low-carbon county with sector-specific messages for all offices, schools, hospitals, factories, retail, leisure and homes.
