    Britain’s first zero-carbon homes are being built—and they look like something from a science-fiction movie.

There are 25 eco-friendly homes currently being built in Southmoor, near Abingdon, Oxon. Buyers are able to have the final say on floor layouts，kitchens and bathrooms. One three-bedroom home is on the market for￡801 ,000,with a custom build available to suit your own specification. These eco-friendly houses are powered entirely by electricity from solar panels around the houses. They also have advanced ventilation (通风) systems, making sure that temperatures inside the building don’t go beyond 25℃ for more than 10% of hours annually, as well as mini heat pumps to generate (产生) the heating and hot water on-site. Part of the cooling design includes avoiding east-or west-facing windows, and window shading.

And they’re in high demand. Ian Pritchett, of Ssassy Property, thinks the Government should do more to promote the construction of this type of housing. “Unfortunately, the Government relaxed the proposed 2016 zero-carbon targets after being lobbied(游说)by house builders,” Ian explained. “At present, the main house-building corporations control the land and only build at the rate they are sure will sell, keeping the UK’s housing shortage so that the normal rules of ‘supply and demand’ don’t apply. When there is a shortage of housing, buyers have to purchase what is available rather than what they might want.”

In any sensible society, we would expect the planning system to actively encourage zero-carbon houses，and he tough on anyone failing to deliver the necessary standard. Instead, we have a planning system that focuses on other aspects such as numbers of bedrooms, garden sizes, and parking places. These are important aspects, but they pale into insignificance compared to the catastrophic consequences of climate change.
