Much time and sweat has gone into the science of climate change prevention. As one of its chief architects, the building industry has also been at the forefront of efforts to ameliorate the effects. But much less time has been spent on constructing homes and commercial properties which plan for the hotter more unpredictable future which most experts agree is coming anyway.

Increased flooding; hotter, dryer summers; loss of biodiversity; and risk to human health are the hallmarks of the scaremonger鈥檚 case for a behavioural change today. But at its most prosaic level, we are looking at a future in 70 or 80 years from now when summers are going to prove an expensive and uncomfortable time to sit around on sofas on a Sunday afternoon watching England battle to prevent a fourth day innings defeat against Australia in the Ashes.

The Department for Environment, Food and Rural Affairs (defra) has recognised this and called for private and public institutions to think creatively about adaptation. It has introduced a website containing the latest information on how climate is expected to alter, links to practical tools for adaptation, and examples of what is already being done around the country.

Climate change minister, Joan Ruddock said the industry needed to think clearly about future proofing buildings. And it has begun to listen. At November鈥檚 Thames Gateway Forum, a talking shop revolved around the vast regeneration project set for development in and around the Thames estuary, the industry will debate climate change and its effect on the building industry in a series of seminars.

鈥淲e鈥檒l need good design that works with the environment rather than against it,鈥� says Ruddock, 鈥渃reating buildings which stay cool in the heat and deal with water that will be in short supply in summer and pouring into the drains during heavy storms. This one stop shop will help people identify the challenges we will face in the future and to make the decisions now that will help us to manage them.鈥�

Summers are going to prove an expensive and uncomfortable time to sit around on sofas on a Sunday afternoon watching England battle to prevent a fourth day innings defeat against Australia in the Ashes.

But Chris Twin, Arup director says the industry鈥檚 fledgling interest and the government鈥檚 website are no more than 鈥渁 first tentative step.鈥� He believes that government and the building industry have been woefully slow to understand the need to plan for adaptation. 鈥淓ven if the technologies and techniques are not used today, they need to be in place for when it becomes an issue in 30 or 40 years time.鈥�

An example is the Bedzed development in Sutton, South London where residents complained that the unshaded sunspace made their living rooms too hot. But that, says Twinn, was because they were using the sunspace incorrectly.

He says: 鈥淭he whole idea of a sunspace is to close it during the day when you are out and keep your inner room ventilated. Then you open it up in the morning and the evening to cool it off.鈥�

The misunderstanding is not an issue for Twinn who says it will take a generation or two before people in the UK adapt to living in a warmer climate. The important thing is that the technology and engineering is there to cope once people are forced to start behaving like southern Europeans.

Adapting to a Mediterranean-style climate means binning many of the rules of thumb which architects use to maximise today鈥檚 temperate north Atlantic climate. Improved insulation and warmer winter temperatures means homes and offices can retain warmth without needing to trap heat from low winter sun with large south facing windows. The corollary is smaller north facing windows which help to prevent overheating in the summer.

The key is to make sure buildings are designed to remain cool without air conditioning until the case for artificial cooling becomes overwhelming in about 70 years, by which time solar powered cooling will be effective enough to provide the one or two degrees C heat reduction which will be required.

But for Twinn, the challenge for architects and engineers goes beyond just homes and offices and out on to the streets. Roads, he says, should be made narrower and either tree lined or shielded with buildings like medieval Mediterranean alleyways to prevent the sun beating down on them all day long. The alternative is empty streets in the daytime.

And as cataclysmic as this prediction might seem to a country whose inhabitants strip down and break out the suntan oil as soon as the temperature sneaks over 16 degrees C, architects and engineers are not equipped to manage the change alone. Twinn reckons that for a built environment equipped for the coming challenges, government needs to require the industry to think as clearly about adaptation as it already does about prevention.

The alternative is the country sweating as heavily in summer as the average English batsman.
