Research On Public Building Shading Design In Cold Region

The main content of this topic research has the following three points: first,cold regions represented by xi 'an public building shading condition investigation of typical large and medium-sized cities,and USES the anonymous questionnaire form for practitioners,green construction assessment personnel as well as the use of public construction personnel crowd research,it is concluded that the current problems existing in the cold area public building shading and attitudes cold area public building shading,the lack of public building shade for cold regions;Second,using the method of scale model experiment,experiment under the different shading form and visor size model space temperature test,it is concluded that xi 'an area,different periods towards the sun and the best way and analysis of the energy saving potential of large and medium-sized public buildings in the region;Third,combining with the characteristics of public property and the energy consumption and analysis of the key issues in cold area public building shading,probe into cold area shading season with shade,put forward suitable for cold areas in our country public building shading design scheme.The second chapter through to the public buildings in xi 'an region window wall area ratio research analysis: large window wall than the proportion of the office is very big,a lot of glass to use is a major cause of lead to its summer cooling energy consumption is too high;From the questionnaire survey results,xi 'an district public building large glass Windows(including glass curtain wall)not using shading reason is various,but mainly is the designer and the user is different understanding of public building shading,the proper shade way public buildings and construction practice has not been research analysis,together with the wide use of air conditioning,make people know shade can bring a good indoor thermal environment and less energy consumption,still don't do shading treatment.Scale in chapter 3 of the numerical and experimental conclusions can undertake building shading clear in cold area,its energy saving is of great significance,architectural shading the energy-saving potential is different due to different orientation and shading mode.For the use of public buildings of large area glass,shading is important to reduce energy consumption of air conditioning and direct means.However,due to the cold areas of public buildings from the perspective of energy saving on winter insulation design,so people to shading design should pay attention to problems tend to be ignored.Chapter 4 based on the architectural shading the re-recognition and the related concepts of cold area solar altitude Angle and azimuth Angle of the analysis of the seasonal change rule,the author clarify the basic problems of cold region public shade;Through to form selection and cold area window sunshade shade to analysis the influence of indoor physical environment,the author roughly clear the cold region in the form of public building shade;Based on architectural shading in summer and winter solar heating contradictory relationship analysis,the author find out the key issues in the cold region public building shading design,and further clarified the shade of the season and time.The fifth chapter puts forward the suitable for cold areas of public building shading design principle and design key points,and puts forward a new type of shading mode is different from the traditional shade,building practitioners and public buildings for cold areas to provide the sunshade design basis and reference.
