The tactics of urban planning and architectural design on urban construction of energy-saving and environmental affinity

People have to increase energy-saving technology of urban planning and architectural design because of the dual crisis of energy and environment. Many countries have drawn up the policy and standard of energy saving one after another. In our country we have planed and designed on a large scale in the aspect of old city's reform, new city's extension and new rural communities construction. Old energy-saving tactic of urban buildings is not enough to meet the needs of development. So it is essential to probe multi-domain's ,all-directional, innovative and more in line with China's national conditions design method and tactics on the basic of national standard of energy-saving design. Environmental load more and more with each passing day should be reduced in order to implement the planning of energy saving and environmental affinity. And it is important to decrease and control load, use efficiently resources and energy, recover prevenient function and create, etc to build safe and reassuring human settlement. It can supply comfortable and convenient life and raise glamour and quality. The field of view on planning is necessary from building monomer to the extent of block and city.The control of entire process from planning to design must be strengthened. The matching technology of the energy-saving planning and design should be explorated and used. The multipurpose use of many methods of architectural design, which including using the natural energy flexibly and efficiently, the control of zeroth energy consumption in indoor environment, interdict energy consumption by structure measure, research and develop efficient electromechanical device ,and so on, may aim at realizing energy saving building of environmental affinity. © 2009 IEEE.
