Unscrambling the Building Envelope Insulation Technique in 'Tianjin energy efficiency design standard for rural residential buildings

摘要

In order to solve problems of high energy consumption and poor indoor thermal comfort in existing rural residential buildings, Tianjin city developed "Tianjin energy efficiency standard for rural residential buildings", the building envelope insulation technique in the standard-including determination of heat transfer coefficient, principle of choosing insulation materials for building envelope, energy efficiency standards of walls, windows, and roofs are unscrambled particularly in this paper. It is suggested that natural materials and appropriate techniques are used to achieve the energy-saving goal for rural residential buildings with minimum energy consumption.
