The solar envelope: how to heat and cool cities without fossil fuels

Energy Bulletin -- Modern buildings rely on a massive supply of cheap fossil fuels for heating, cooling, and lighting. Take the supply of cheap fossil fuels away, and they become completely uninhabitable for most of the year: they are too cold, too hot or too dark. This radical change in architectural design was caused by both the arrival of cheap and abundant energy sources and the resultant urbanisation. The Industrial Revolution relocated millions of people from the countryside to the cities. When most of us lived and worked on farms or in hamlets, it was fairly easy to orientate one's house towards the sun. In an urban environment, however, building orientation is generally determined by street layout, and one building can easily overshadow another. High-rise buildings further complicate solar access.

Energy from Solar, water, wind, & fire (from wood etc.) were being used long before Petroleum. It became King because of efficiency & availability among other reasons. To replace it you have to build "the better mouse trap" and they haven't been able to succeed in that so far. Thus Government again is trying to force something onto the people that isn't really in existence yet.

As the article points out, we don't need to rely on fossil fuels. Time for alternate energy.

That was a slog, but worthwhile and interesting. Mostly glad we live in suburbia, while we are stuck with the direction the house faces we don't have to worry about other factors.

Great idea, and thanks the poster for this one. eromitlab.

I working on forming a solar Hot water company, but in my research have decide to make shop building solar heated in the winter, through simple hear exchanger system on the south catherdal ceiling.

Density is a pet subject of environmentalists, who argue that densely populated cities are the solution to lower the energy requirements for transportation. On the other hand, the solar envelope shows that above a certain treshold, density can also raise energy requirements, in particular those of heating, cooling and daylighting buildings.
