| According to China's economic rapid growth and the improvement of people's living standards, dwelling concept and requirement is in a tremendously change. Dwellings begin to develop from"quantity"concept to"quality". The use of installation to have indoors warm in winter and cool in summer already become a design trend. Building envelope and indoor environment are closely linked with each other. This research focuses on how to design building envelope in order to improve the indoor environment's quality as well as to reduce energy loss.From six chapters, the first chapter introduces a brief history of building envelope development and its relevant theory to the research- sustainable development theory and residential theory. The second chapter involves heat comfort and the factors influence to indoor thermal environment, from traditional building envelope design practice compare with present science and technology standard practice and living pattern. The objective is to improve building envelope's design tactics in nowadays dwelling in order to control the flow of energy. The third chapter is discussed firstly, how to preserve indoor energy, especially the movement of heating and air conditioning and secondly, what is building envelope's role or task in heating or cooling energy preservation. The analysis of this from wall, window and to the roof are presented. The forth chapter, energy prevention, discussed how to keep the indoor from over heat in summer by using sun block and ventilation strategies. Chapter 5, energy absorb, describes how to apply building envelope theory in practical with passive means. The last chapter analyzed energy consumption of residential project in Ningbo by using DOE-2 software. |
