Research On The New Type Of External Blands Based On The Concept Of Energy Saving

Building shade, the principal means of resisting the sun radiation and improving the indoor thermal environment, has been researched widely in south China. And it is widely used in energy saving buildings.With the deterioration of the climate, temperatures in northern cold region are rising year by year and time continues for a longer duration in summer. What’s more, very few application of building external blinds is used in north China, it is not good for building energy saving. Architectural shading design, which belongs to the category of building climatology, attaches strongly regional adaptability, climate and geographical environment, accordingly architectural shading design in the northern area cannot plagiarism the design in the southern region. Reducing heat in summer and collecting heat in winter should be considered at the same time in cold region. And the outside blinds can resist the sun heat in summer and reduce the heat dissipation through window in winter, and they can enrich the building outside modeling as well. So this paper mainly study the blinds combined the climate in cold region and research the applicable blinds design to promote the development of building energy efficiency in cold areas.At first this paper points out the insufficient in the existing shade in cold areas of our country by the analysis of the existing research and practice at home and abroad. This paper aims at exploring performance characteristics of a new blind by combining with cold areas climate, which applies to cold areas. The new blind model is put forward in this paper aiming at the problem that existing blinds can’t satisfy the heat preservation and heat insulation and provide a vision for indoor personnel at the same time. Energy-saving analysis software, Autodesk Analysis Ecotect, is used to analysis the simulated data to research the best parameters of new blinds and design a new one to satisfy the needs mentioned above. At last, the details about the structure of the new blinds are studied, including the structure of the new blinds and the way of connecting blinds and windows. The new type is designed to improve and perfect realization way of the new blinds and the development of energy-saving for buildings in cold region forms.
