Abstract:
Over 40% society energy consumption is contributed by the construction industry, where the building materials play an important role in the energy saving performance of a building. Research reveals that the energy consuming of air conditioning and heating system has taken 70% of the overall building energy consumption through all its life cycle, mainly due to the thermal transmission of building envelope structure. Therefore, this paper focuses on the exterior heat insulators, windows and wall materials, which are critical to building heat-insulating property, to study their resource consuming and environment impact during the life cycle from mining, production, transportation, utility, until disposal. In the end, the author aims to provide a robust rationale and database to optimize environmental friendly material selection for the green building.
