Micro Climate Perspective Settlements Outside Space Environment Ecological Optimization Design

Micro climate- the micro perspective of climatology, external space of residential environment is important and comprehensive. Through the micro climate of the concept of carding, reveals its constituent elements, and discuss the factors’ influence to external space environment design of residential and characteristics. For residential building energy efficiency, full use of natural conditions, climate, resources, or from the residential users comfort point of view, in today’s increasingly serious environmental pollution, the subject is particularly important.The first part put forward the micro climate and settlements of external space environment analysis, refining their basic components,exploring the relationship between elements. Combined with the related research, summarized the micro climate elements standards meet occupant comfort, provide theoretical basis and data support for the next step of simulation and optimization design.The second part put some settlements in tianjin area as the main research object. In view of the actual typical architectural layout, through to the tianjin hexi district of field survey and data statistics multiple residential research, summarized in the modern residential planning and design, usually ignore the common problems such as the user’s comfortableness, and summarize tianjin residential common architectural layout mode.The third part, at the same time,summing up the basic mode of typical architectural layout, based on tianjin climate characteristics, use EOTECT simulation software, the solar radiation simulation, winter summer monsoon environment simulation.First of all, analyze the building layout. Then, according to the above solar radiation simulation, winter summer wind environment simulated wind figure and work out the best position, using the method of overlapping, the position of the optimal activity area, the setting of road system, and the best possible conditions. Finally, according to the simulation of wind environment vector diagram and the activity space is obtained and the overlay, the road system and according to the fundamental principles of wind in winter, summer ventilation, to set up the shade of green landscape, even water system Settings.Through the above research work, not only profoundly discussed the layout characteristics, it summarizes the best basic layout mode of "negative Yin embrace Yang, is summarized according to the results of software simulation, attention to the outer space environment optimization design method of the basic strategy.Finally, practical engineering case to prove the best basic layout pattern and settlements outside space environment design method can be implemented.The six for tianjin rural residential area, combined with the discussion of the results of the simulation software, the best design patterns, adjustments to its architectural layout, the location of the activity space optimization. Energy-saving residential planning design should start from the beginning of the design, planning construction layout can be more in line with the ecological principle; In the same climate conditions, increasing the settlements residents comfort in outdoor activities.
