The definitions and standards for "low energy" buildings vary from country to country. For example, the USA, in broad terms, regard homes that use at least 15% less energy than standard new homes as a low-energy home, although many homes achieve 20%-30% savings.

To design and build a low-energy homeyour need to combine any number of passive and active energy savings and energy generation techniques. But for future generations, the building of "green", eco-friendly and low-energy buildings are becoming a major issue in many countries.
