Hot Summer And Cold Winter In Residential Buildings In The Roof Structure Energy-saving And Environmental Design

Residential roof and direct dialogue took place outside of the natural environment, the most vulnerable, such as wind, such as rain and snow weather conditions. The top-level households, the roof of the building as an external structure caused by the temperature difference between indoor and outdoor heat transfer heat, more than any side of the wall and ground heat.It was on the hot summer and cold winter areas(Xiang Tan city) of residential construction survey results show that: the top-level power consumption for households as a whole 27.91 kw.h /㎡, in the middle tier of households throughout the year that the power consumption of 17.04 kw.h /㎡, and the bottom of household electricity consumption for the year 12.66 kw.h /㎡. It is worth noting here that top-level power consumption of households and the bottom of households compared to 120.46﹪more, but the vast majority of families in the summer and winter of great power. This shows that the building envelope in the area of energy-saving measures fall far short of the national energy-saving standards.We are usually in the construction of energy-saving structural study, the research is the structure of the internal factors, namely, the physical properties of the structure. For example, the energy-saving construction materials used, the structure of energy-saving features, structural level, structure and so on technical points. However, we often lose sight of the external structure in the form of research, such as: energy-saving materials, color, texture, materials, environmental protection, materials, energy-saving construction space in the form of expression, as well as the structure surrounding the environmental impact and so on. In the study of the built environment, we often only existArchitectural study of the external environment, the arts, the environment, such as color, shape and space to express, and so on, but ignores the inherent features of the built environment research, such as the construction of the internal environment features: Optics, acoustics, the application materials to the environment quality of life and many other technical functions. Therefore, only when we are building will be constructed with energy-saving building up a comprehensive environmental study, can we really designed not only energy-saving, environmental protection and practical, beautiful building.The focus of this research is related to hot summer and cold winter areas of the roof of the building energy-saving construction and design of the roof of the built environment of the organic, made the best residential building in the area of energy conservation in the form of the roof.
