Study On Residential High-rise Passive Energy-saving Design In Shijiazhuang

A collection of high-rise residential building in the 1990s as an important means to improve the volume rate began large-scale promotion of universal,with the rise of high-rise residential buildings,high-rise residential building energy consumption is gradually revealed,in addition,there are still affecting the living environment,public lack of space and other issues.Building energy consumption accounts for more than 27%of all energy consumption,and an annual rate of 1 percentage point increase.In building energy consumption,heating,cooling is the most energy-intensive,accounting for more than 60 percent of the overall proportion.Statistics show that China's unit of floor space heating energy consumption is 2-3 times the climate is similar to the state.In Shijiazhuang,Hebei Province,the maximum air-conditioning electricity load is about 150-2000000 kilowatts,accounting for 26%to 35%of the city's peak load of society;the total building electricity load accounted for more than 43%of the total load,and there increasing trend.Aiming at these problems,based on passive energy-saving methods of research on high-rise residential design in Shijiazhuang,Hebei Province,to be part of the preliminary design stage in building energy consumption and livable solve the problem of inadequate collection of high-rise residential.In order to achieve a comfortable indoor thermal environment,as far as possible through rational design passive approach designed to minimize the active non-renewable energy consumption amount.Select the appropriate technology of choice for building passive energy-saving design,the direct use of renewable energy as much as possible,avoid energy conversion;should also be encouraged to adopt cost-efficient technology to avoid the blind pursuit of zero-energy and high-tech.Passive energy-saving materials and technologies in addition to rely in good design skills can also significantly reduce both energy consumption.Therefore,the emphasis on the design level research papers,trying to involve fewer levels of technology,but more to explore fundamental concepts and principles of passive heating and cooling.Thesis on the theory and climate profiles passive Shijiazhuang prior analysis and study,by Survey of Shijiazhuang high-rise residential analysis,using analogy,induction,case analysis and comprehensive survey methods.Energy consumption and energy saving in Shijiazhuang gave rise residential appraisal,then propose optimized passive design deficiencies and potential for the status quo.Papers were outside the building environment from passive energy efficient design and construction of energy-saving design single passive Shijiazhuang two aspects to make possible high-rise residential energy-saving measures,described its passive design elements.Examples of high-rise residential and conduct analysis,the passive energy-optimized design.Subsequent sections from the application point of passive heating and cooling,as well as passive energy-saving system integration design study,the first to study the high-rise residential population distribution under the south facade of sunshine long problem,and analyzes the high-rise residential flat,profile organization and solar integrated use of passive design issues;secondly for the underlying processing high-rise residential,balcony form,roof forms and other interface features,the external interface to integrate passive energy-saving design of the inquiryThe final conclusion in part based on geographical factors and climatic conditions in Shijiazhuang City,Hebei Province,made from high-rise residential layout,the external environment and the monomer passive energy saving aspects of the design phase of optimization and integration of design patterns.High-rise residential development on future trends and energy-saving potential to make certain predictions.
