David is author of What colour is your building?: Measuring and reducing the energy and carbon footprint of buildings. Testimonials for the book are reproduced below:
'This book has a key role to play in the development of this important new approach to sustainable urban environments... Using clear, transparent data, it places in context the energy and CO2 emissions associated with the construction and operation of buildings. But more than that, it challenges all those involved in the built environment – policy makers, planners, designers, builders, managers and occupants – to focus on the issues that make a difference.
This book is an accessible, practical guide to reducing energy consumption and CO2 emissions, providing a fresh approach but grounded in commercially available technologies.'
Sir David King, Chair of Future Cities Catapult, Former Chief Scientific Adviser to the UK Government, Senior Science Adviser to UBS
'What Colour Is Your Building? is an important and timely guide to help us navigate the often misunderstood subject of energy use in and around buildings. This is not an academic pursuit, it is an urgent course of action that we must embark on to harvest the most cost-effective energy and carbon savings, and one in which everyone associated with planning, design, construction, occupation and management of buildings needs to play a part. Debunking myths and providing a simple step by step guide to measuring and minimising real energy use, this is essential reading.'
Paul King, CEO of UK Green Building Council
'The premise behind David Clark's What Colour Is Your Building? is a yearning for answers that can deliver meaningful change. What Colour Is Your Building? not only finds practical and realistic solutions to the problem of carbon, it does something even more significant: it forces us to confront the limitations of our knowledge and changes the nature of the inquiry.
Rooted in evidence, tempered by experience, and focussed on performance, What Colour Is Your Building? is an indispensable read for anyone who is serious about tackling carbon emissions. As the environmental and financial converge, David Clark's work presents a clear call to action based on the fundamentals that are indisputable for any good business case.
The ideas presented by David Clark are original, actionable, commendable and ultimately profitable. We can only hope that more practitioners follow his example and that more decision-makers heed this advice.'
Richard Francis, Director of Environment & Sustainability at Gardiner & Theobald and Chair of BCSC Low Carbon Working Group
'Data presented clearly, and with a touch of humour, make this a very good and timely read. The industry has been learning a lot about how to – and how not to – design, construct and manage green buildings. David's book is a concise, accessible summary of the lessons.'
Pooran Desai, OBE HonFRIBA, co-founder BioRegional and International Director, One Planet Communities
'This book clearly sets out the importance of considering buildings in the round, as a whole system. I'd make this compulsory reading for all 'built environment' students and certainly would encourage all practitioners with an interest in the sustainability of buildings to put it at the top of their reading lists. In addition, policy makers involved in the carbon and energy arenas should inwardly digest this book as soon as possible.'
Miles Keeping, Partner of Deloitte Real Estate and Chairman of Investment Property Forum Sustainability Interest Group
'We need technical, economic and aesthetic success stories to dramatically improve the environmental performance of our building stock. What Colour is Your Building? offers a rare combination of asking the right questions and providing detailed answers and is essential reading for all sustainable construction and property practitioners.'
Steven Borncamp, co-Director of Construction21: International, Managing Director of Living Future Europe and Founding President of Romania Green Building Council
'David is one of our leading exponents of low energy buildings. I commend this work to designers and contractors, as an embodiment of professional expertise, scholarly insight and remarkable common sense.'
Andrew McNaughton, CEO Balfour Beatty plc and Vice President of the Institution of Civil Engineers
'This is a timely and very significant work, one of the first to look comprehensively at the energy and carbon impacts of buildings in their totality. David Clark has combined experience distilled from many years as one of the UK's leading building engineers with the latest thinking to provide a compelling account of energy use and carbon emissions at all stages of the building life cycle. More than that, the book provides detailed practical guidance on reducing carbon emissions for all involved in the design, construction and operation of low-energy buildings. Guidance and data is clearly presented and in a straightforward way free from jargon. I would commend it highly to practitioners, clients and researchers alike.'
Professor John Connaughton, University of Reading, School of Construction Management and Engineering
'In the 20 years since we designed our first radically "green" building, the tension between myth and reality has continued unabated, largely due to a lack of real performance data combined with vested interests opposing change. This lucid and comprehensive book demonstrates that lower environmental impacts – critically the reduction of carbon dioxide emissions – can be achieved through design strategies based on a sound understanding of actual building performance. Its message is that the requisite knowledge isn't rocket science; it requires scientific rigour and design innovation for sure, but common sense and objectivity are the primary requirements for the green buildings of the future.'
Rab Bennetts, OBE, Director, Bennetts Associates
'As the Chair of the World Green Building Council, I have a deep respect for the rating systems that help project teams, building owners, and facility operators measure the impact of their buildings and help them make better decisions. But real performance is tied to better metrics and more transparency across every dimension – energy, of course, but also water, waste, and materials. David's call to action rings true for anyone who sees better buildings and communities as the cornerstones for a better future.'
S. Richard Fedrizzi, Chairman of World Green Building Council and President, CEO and Founding Chair of U.S. Green Building Council
'Investing in green buildings can not only reduce carbon emissions and cut costs, but create jobs and revitalise entire communities and cities. With practical information, real world data and case studies, David's book is a valuable contribution to the growing body of knowledge about green building, and will help the global property and construction industry's transition to a more sustainable future.'
Romilly Madew, Chief Executive of Green Building Council of Australia
