Research Status and Consideration on the Relationship between Natural Ventilation and Energy Consumption of Residential Buildings

Abstract

Natural ventilation is an important way to bring about energy-saving benefits. So one aim of this paper is to focus on the relationship between natural ventilation and energy consumption of residential buildings in China and other zones; list many studies based on this relationship and present a varieties of factors which are closely related to natural ventilation and affect energy consumption, such as ventilation strategies, climatic conditions, window parameters. Another aim is to provide some consideration by analysis and summary of relative researches, it is found that most studies are to evaluate the energy consumption about natural ventilation in residential buildings from only one or two factors, few people combined three, four or more factors to study, we need to form a system in order to guide building design in the future. In addition, the energy-saving economy index is introduced to evaluate the economic of energy-saving design about natural ventilation in residential buildings.
