Burhan Ergüner, Design Development Director, Metal Yapi, presented an innovative natural ventilation system for these tall buildings.

Fırat Oğuz Edis, a Professor of Space Engineering Department of Istanbul Technical University, shared experimental results obtained in the EDS Wind Laboratory.

Murat Seyhan, CEO, FTI & FTI-Wacker shared information about the tests to determine the performance of the façade systems.

ISTANBUL – On Tuesday 18 June 2019, CTBUH Turkey organized the Wind Effects on Tall Building Façade Systems seminar. The event was hosted by MBY at ITU Teknokent. Guests from a variety of disciplines attended the seminar and expressed enthusiasm in hearing presentations on wind effects on tall building façade systems.

The evening kicked off with CTBUH Istanbul Representative Mehmet Kılıç, Country Director (Turkey), Turner International, providing a brief introduction of the Council, its mission, and various initiatives.

In his presentation, Burhan Ergüner, Design Development Director, Metal Yapi, pointed out that most dominate and persistent effect on the façades is unquestionably the wind load. In the course of his presentation, he focused on sustainable design. Furthermore, he stated that when the construction field is introduced with new methods of technologies, architects can design taller buildings. Ergüner also emphasized an innovative natural ventilation system for these tall buildings that can operate in extreme weather conditions such as thunderstorm and lightning. Then, he presented a high performance, high wind-resistant and special sliding system which is designed to provide natural ventilation in high-rise residential buildings.

Dr. Fırat Oğuz Edis, Professor, Istanbul Technical University, started his speech by defining turbulence, mean components, gradient and directivity of the wind. Next, he introduced the interaction of the wind with the building structure. He briefly mentioned the field of wind engineering on tall buildings. For instance, pedestrian comfort, occupant comfort (based on vibrations of floors), determination of loads both for claddings and entire structure. Edis compared the capabilities of experimental and computational wind engineering, and explained the pros & cons of these methods. During his enlightening presentation, he shared  experimental results obtained in the EDS Wind Laboratory.

The last presentation was made by Murat Seyhan, CEO, FTI & FTI-Wacker Ingenieure. The topic of the presentation was “Wind Effects and Performance Tests.” At the beginning of his presentation, he presented remarkable field research. As a result of the inspections carried out in 140 buildings, 46% of the building shell defects were reported to be in horizontal systems, 26% in vertical systems and 25% in operable systems. He categorized the causes of problems in façade systems into three groups:  design, assembly and material. In order to solve these problems, Seyhan suggested the use of quality control processes. For the rest of his presentation, he shared information about the tests to determine the performance of the façade systems.

The seminar concluded with a panel discussion. The event was organized by CTBUH Turkey Future Leaders Committee members İlayda Öner, Business Development Engineer, Turner International; Emre Toprak, Senior Structural Engineer, Arup and Burak Yılmaz, Founder, MBY. This event was kindly sponsored by Turner International and MBY.
