Study On The Big Space's Natural Ventilation

Analyzing from the perspective of the world's energy consumption, energy conservation in buildings is necessary. It is a practical way to use natural ventilation for saving energy consumptions of a building through the researches.Natural ventilation does not belong to a new technology,human beings are also rich in the experience of using natural ventilation.However,it is more and more obvious when pepole depend on the technologic devolpment, natural ventilation technology focused on traditional technology had been forgotten.The conflict between energy consumption and social development makes natural ventilation better developed.It is scientific and effective for the modern buildings using natural ventilation methods combined the modern technologic analysis with the architectural design,In the process of the architectural design, calculations and analysis should be based on building size, usage, flow distribution,comfort requirements etc. Certainly,natural ventilation system in green buildings is only a part of the systemic ecologic design,it is difficult to meet the require of comfort alone.To choose a technology of natural ventilation should have the systemic concept,regard the technology of natural ventilation as an important ecologic means,and also take other technical measures such as envelope insulation and shading into account.In a variety of building types,energy consumption for a large space because of its spatial characteristics is a large factor in particular,it is important to adopt energy consumption in large space.This paper mainly researches natural ventilation in large space,simulates different schemes by Airpak software,and selects the best option to achieve natural ventilation.The architect's design is the premise for a building whether achieves natural ventilation.The architect should grip the natural ventilation technology and apply it for architectural design.This article summarizes a variety of natural ventilation technology applied in architectural design,provides the basis for the design of natural ventilation using the methods of software analysis,simulates the influence factors such as the location and the size of the ventilation openings of a building,finally achieves the optimal design of natural ventilation.
