Retrospect last century, it is not difficult to find that, while human’s living ways and living states are changing enormously, they cost lots of source and energy, which leads to environmental pollutions and resource’s shortage and have a bad effect on ecological balance. To urban architectures, the developing mode has to be done from traditional high-consumption developing mode to low-consumption and low-pollution developing mode. Ecological architecture is the essential way for such transformation and also the essential trends to current world development. Ecological architecture refers to minimum affect environment; make full use of environmentally natural resources to realize high-efficiency utilization of resources and energy; satisfy people’s demands with healthy, applicable and effective living environment, to achieve harmony between man and architectures; it is a big and complex systematic engineering including nature, society, economy and civilization, etc. Only if in a balanced state, the ecological architectures can be realized in overall significance and realize the object of sustainable development. Ecological construction in the design process should follow the overall design principle, Low-consumption and pollution-free principle, decrease the consumption on materials and energy, improving the utilization of energy, decrease energy consumption of architectures by smart architecture systems. Designers also have to make reasonable use of sunlight, wind, rain and other natural energy according to various climate characteristics, design properly, decrease waste of non-renewable resources and advocate the recycles and reuse of energy. This paper analyzes design methods of ecological architecture from aspects of water utilization, energy utilization and ecological buildings, etc., and explores relationships of man-nature-environment, so as to start architects’ thoughts in resolutions to effects on environment from the source.
