Summer Thermal Environment And Planning For The Residential Districts In Cold Area

As global climate warms gradually and hot island of city was aggravated, partial cities of our country in the cold area have also arisen the summer extremely hot climate . In order to get comfortable thermal environment, people begin to use the conventional energy unlimitedly. As a result, it makes the hot island effect more serious , and have formed the course of vicious circle. To build an ecological district, it becomes a urgent task, that the person must explore and construct a good dwelling environment, which is combinated nature and has a good cycle of ecology.With the method of theoretical analysis and the data analysis, Paper has analysed summer thermal process in cold area, and has found out the factors, the region climate, building environment and architectural form, which affect the thermal environment of the district in summer. Natural climate condition, the self -quality of the building and comfortable standard indoor is the determinative factors of the building energy consumption. Residential district planning design must emphasize to research the relation between building-form and region climate as well as the biological feeling of human-body; architecture design must follow climate-design principle, which is knowing and grasping local climate feature, through environmental design and building means, to apply the passive technology of low energy consumption combined local climate as far as possible; and eliminate the disadvantage effect of outside climate on the comfortable thermal environment as far as possible, consequently raise comfortable environmental quality while reducing traditional energy consumption.Based on summarizing the measures of constructing comfortable thermal environment (indoor and outside) in cold area, the paper has put forward the " use " > "defend" and "eliminate" principle. Through reasonable designing, solve the environmental problem and the comfortable problem, which usually need equipment consume to solve, and reach the natural harmonious unification between building and human being. Offer a kind of "green" train to architect, a kind of the "green" method in the residential district planning design, eventually get to a green-key of residential district design in cold area. Finally, the paper discussed prospect of this subject, and pointed out the directions, which need to keep on researching for us.
