The Urban-rural integration means cities as the driving force to boost the development of rural areas.

Under the condition of orderly division of functions and organic coordination, urban-rural integration network is formed, with resources and service preferentially to the countryside.

Passive house is an energy-efficiency building by intertwining various energy saving methods, such as natural ventilation, natural lighting, solar radiation and indoor non-heating heat source, with energy saving envelope structure.

ICF can significantly reduce the energy consumption while drastically improving the indoor environment, minimizing the dependence on mechanical heating and cooling, eliminating the building from fossil fuel. In the long run, life of the house can be greatly extended and environment can be protected as well.

Passive houses claim the only way for mankind to achieve sustainable development. They are not only the trend of energy-saving building, but also the trend of the whole construction development in China.
