Systematic Analysis on Sustainable Retrofit of Typical High-rise Community Based on Building Performance Simulation Model


Abstract: This article presents a methodological procedure of high-rise community retrofit and takes Xinyuancun residential district in Tianjin University as a case study with simulation-based process which demonstrates a „whole house’approach combining form, fabric and system strategy in order to promote occupant comfort and reduce house-hold energy consumption without prejudice optimization of aesthetics attributes in retrofit design. In this article computer-based simulation is utilized as a flexible method in diagnosis, prediction, and determination. A hybrid method is used to assess occupant comfort and energy performance of existing building in order to diagnose the retrofit potential. Then built environment elements (fabric, ventilation and light) of potential buildings, are predicted and quantified before and after retrofit by using DesignBuilder, PHOENICS, and Ecotect. These simulation results are aim to determine the most effective retrofit strategies. The findings validates that simulation can provide guidance to the organization and implementation of retrofit process. The integrated „whole house‟ approach rather than „elemental‟ strategies, can serve as a multi-objective optimization approach for retrofit which can balance energy consumption, occupant comfort and architectural aesthetics.
