TAMPERE – The 25th edition of the Glass Performance Days Conference (GPD), chaired by Jorma Vitkala, GPD, and focusing on “Growth, Knowledge, New Generation,” was held at the TähtiAreena in Finland from June 28 to 30, 2017.

On June 29, CTBUH Research Manager Dario Trabucco presented a paper published in the GPD 2017 Conference Proceedings, entitled “Cyclone Resistant Glazing Solutions in the Asia-Pacific Region: A Growing Market to Meet Present and Future Challenges.” The paper was authored by Trabucco; CTBUH Research Assistants Angela Mejorin and Will Miranda; and Reisuke Nakada, Christoph Troska, and Ingo Stelzer of Trosifol.

The paper summarizes the findings of the research project “Cyclone-Glazing and Façade Resilience for the Asia-Pacific Region” that is currently being conducted by CTBUH, thanks to a research grant received from Kuraray –Trosifol. The risk to tall buildings due to typhoon events in the Asia-Pacific region has been examined in detail on a country-by-country basis through Geographic Information System (GIS) modeling, using data from The Skyscraper Center and historic typhoon event data from the United Nations Environmental Program. In the countries discussed, a total of 6,618 tall buildings were analyzed, with 1,772 having been affected by a typhoon event in the past, and a profound 4,290 buildings currently in a typhoon-prone area.

Current state-of-the-art cyclone-resistant façade technology requirements in the Asia-Pacific region have been investigated and compared against the best practices. The purpose of the research is to sensitize Asia-Pacific governments on security issues for typhoon-resistant façades. As mentioned in the paper that Trabucco presented, “[Tall buildings have] always represented a symbol – for a company, for the society, a landmark in the city. This kind of construction has to follow the best practice for typhoon-resistant glazing because in addition to interior damage, the potential effects to the external area due to storms is invaluable.”

During the conference days Mejorin and Trabucco submitted two surveys to the expert attendees. The first survey disseminated the current research to the professional community, with a view to collecting more information about the Asia-Pacific façades market. The second survey was created with the goal of identifying the main gaps in Asia-Pacific glazing system requirements.

The 25th edition of the GPD Conference was held at the TähtiAreena in Tampere, Finland.
The GPD event represented the chance for the second face-to-face CTBUH research project meeting with Trosifol experts, which was held at the Cumulus Koskikatu Hotel in Tampere on Wednesday June 28, 2017. The final output of the first phase of research – code analysis and identification of main gaps in cyclone resistant glazing systems requirements – was discussed. This phase of the research will address a major problem faced by contractors operating in the Asia-Pacific region: the decision on which code to comply with.

In some Asia-Pacific countries, US standard tests are required, but, in most cases, no test requirements are needed for the façade construction authorization process. Australia and New Zealand currently offer the most advanced codes and standards for the region, but they still differ from the best practices in the US. Furthermore, many analyzed countries have been affected by typhoons every year in the past decade, but they still don’t have typhoon resilience construction safety requirements.

Possible future phases of the research were also discussed during the meeting, including the proposition of a new general guideline for the design of typhoon-resistant façades in the Asia-Pacific market.
More than 650 international professionals gathered for the exciting glass industry event.
