Abstract

En 中文

It remains challenging to conduct an efficient dynamic facade design. In this article authors try to address this issue introducing the facade daylighting performance improvement (FDPI) indicator aimed to evaluate the performance of a dynamic (adaptive) facade from its daylighting performance point of view. To illustrate the FDPI application the authors introduced the preliminary dynamic facade concept for an office building located in Tel Aviv (Hot-summer Mediterranean Climate Csa) with further shape modification based on the daylighting performance analysis compared to the three alternatives representative of different typologies of dynamic facades. Al Bahr, One Ocean and The University of Southern Denmark facade systems were simulated under the same weather and building conditions of the preliminary dynamic facade concept and were considered as a benchmark for the study. The final dynamic facade concept elaborated by the authors in the preliminary comparative workflow showed noticeable daylight performance improvement with respect to the case studies comparative scenarios. The FDPI metric allowed to estimate a daylighting performance improvement of 43% of the final dynamic facade concept over the case study dynamic facade that showed the best performance in the daylighting simulations.
