Energy Efficiency Evaluation of Guangzhou West Tower Facade System1

摘要

Guangzhou West Tower is an extremely tall public building. The energy efficiency evaluation of its facade should be different than that of ordinary public buildings. Based on the national code GB50189-2005, "Design Standard for Energy efficiency of Public Buildings", typical meteorological yearly data for Guangzhou were used and revised according to architectural character of Guangzhou West Tower. The energy efficiency design of a single skin facade and active airflow curtain wall was analyzed by a dynamic energy simulation tool and modified weather data. The payback period of initial investment in the facade system was evaluated based on simulation results. In addition, the results confirm the facade system scheme of Guangzhou West Tower.
