Strategies Summary And Quantitatively Analysis Of Natural Ventilation Passive Energy-saving Building In Cold Areas

Air conditioning energy consumption accounts for a large proportion of energyconsumption in buildings, the use of natural ventilation technology to reduce buildingenergy consumption has important significance for the sustainable development of thewhole building and the community. Currently, the development of green buildingconcept conceived through trial and error stage and the macro level, the micro levelhas gradually entered experience and quantitative research. This article is discussedin cold regions passive energy-saving building natural ventilation strategy.The first chapter is the introduction, stating the background and significance of thetopic of the article, summarizes the contents and results at home and abroad, a cleardirection and research methods. The second chapter of this paper is the concept ofanalytical part, the first part of this article explains the meaning of the topic " sectionpassive natural ventilation in cold regions can Strategy" and defined the scope of itsresearch. Secondly, from a different perspective on the current common passivenatural ventilation energy-saving measures are summarized, and lay the foundationfor further study. Again, discusses the role of passive energy-efficient naturalventilation and indoor thermal comfort period the basic requirements, the content willbecome an indispensable part of the test and reference premise. The third chapter isthe focus of this article, on the basis of qualitative summary, using CFD fluiddynamics simulation software Airpak specific conditions of different strategies in thequantitative analysis of effects, from the micro-level effects of different ventilationstrategies in cold regions environment under use. Through computer simulation, thefirst group of buildings under wind pressure layout, feature set, catching the windcomponent (to catch wind well, for example) the role of quantitative analysis carriedout. Secondly, to pass under the hot high spatial effects were analyzed simulatedsolar chimney. Finally, research is under complex conditions and pressure hot jointaction. The fourth chapter gives three examples of cold areas of green buildingconstruction, ventilation strategy was discussed.
