The increasingly widespread effects of climate change and continuous uncertainty of conventional energy supplies are causing an increasing demand for the transition of our cities through sustainable urban development. However, we are not yet yielding sufficient carbon savings to suggest that adequate action has been taken. The quickest way to reduce greenhouse gas emissions is by being more efficient with the way we consume our energy, by reducing consumption, and by transferring to renewable energy sources. Energy savings require the development and use of more efficient appliances and the retro-fitting of the existing building stock to make the most of natural daylight, rainwater, cooling breezes, and solar exposure – reducing or eliminating the need for artificial lighting, cooling and heating (over the last 20 years, the demand for cooling has increased the most).
