Cyclone-Glazing and Façade Resilience for the Asia-Pacific Region
Stage 2 – Current Problems and Existing Solutions
Project Started: January 2018
Anticipated Project Completion: December 2018
Funding Sponsor:
Trosifol
Principal Investigators:
Dario Trabucco, CTBUH; Antony Wood, CTBUH; Angela Mejorin, CTBUH; Ray Nakada, Trosifol

CTBUH received $116,200 in funding from Trosifol to embark on Stage 2 of the successful research project “Cyclone-Glazing and Façade Resilience for the Asia-Pacific Region.” Stage 1 of the research investigated current, state-of-the-art cyclone-resistant façade technologies requirements in 12 Asia-Pacific jurisdictions. Stage 2 of this research will dive into the specific problems with cyclone glazing, through the analysis of the effectiveness of solutions for existing projects and buildings. In order to identify the most optimal strategies used in the construction of cyclone-resistant structures, this stage of the research will examine specific case studies in four cyclone-prone jurisdictions.

Project Overview
A study of existing standards and best practices for the design, construction, installation, and post-event inspection of curtain walls in 12 cyclone-prone Asia-Pacific jurisdictions has been carried out by this Research Project – Stage 1. First, in cyclone-prone areas, this issue is strongly related to the general safety of building occupants and of the physical property.

Looking at these 12 analyzed jurisdictions – Australia, Bangladesh, China, Hong Kong, India, Japan, New Zealand, the Philippines, South Korea, Taiwan, Thailand, and Vietnam – only four already have standard testing procedures for cyclone-resistant glazing systems in their building code, although they all are frequently hit by high-intensity cyclones. These are Australia, New Zealand, Bangladesh and the Philippines. In Japan, the testing requirements are changing in order to adapt foreign standards to local building component characteristics, and to adopt these procedures.

Stage 2 of the research project, “Cyclone-Glazing and Façade Resistance for the Asia-Pacific Region,” presented herein, will dive into specific problems through the analysis of the solutions found for new and existing buildings in four Asian jurisdictions: Australia, Hong Kong, Japan, and the Philippines. Australia has its own rules for cyclone-resistant façades. Hong Kong has no requirements for cyclone-glazing at the moment. Japan is improving its rules by studying international standards on specific topics. The Philippines adopted US standards to certify its curtain walls.


Cyclone intensities in the Asia-Pacific region.

Thus, in order to identify optimal strategies for the construction of cyclone-resistant structures in the Southeast Asian market, this stage will examine specific case studies. Through the collection of case studies, which are under construction or which have undergone a façade retrofit process, CTBUH aims to summarize the best adopted solutions in terms of:

        - Feasibility of adoption by existing projects (technical and cost sustainability);
        - Economic viability of cyclone-proof solutions on new buildings in each jurisdiction.

The ultimate objective of the second stage of the research is to:

        - Identify current solutions for curtain walls in selected cyclone-prone jurisdictions (Australia, Hong
          Kong, Japan, the Philippines);
        - Identify solutions in the case studies that are compliant to meet local/client requirements for
          cyclone-proofing;
        - Create a Technical Publication, which presents and evaluates the selected case studies.

This Technical Publication could be used as a preliminary guide for industries and professionals in the design of new façades and in the renovation of existing curtain walls.

This work will be conducted with the support of the international panel of experts formed during Stage 1 of the research (Market Study and Code Survey) and of building owners, building managers, and façade contractors.
