Common problems with building envelopes:

Spontaneous breakage of tempered glass has been complained of by many building users. Nickel sulfide inclusions in the tempered glass are responsible for most such breakage. The heat-soak test, which is very effective in breaking the tempered glass with potential danger for spontaneous breakage in an oven, can only be conducted on the glass before it is installed.

An on-site check on the tempered glass to identify the glass with a high-risk of spontaneous breakage has always been a dream to many building users. Wilson Curtain Wall Consultant (HK) Limited has used a non-destructive method to test and check the tempered glass on site to assess its future risk of spontaneous breakage for several projects. Results are encouraging.

Water leakage through curtain walls or windows is a great inconvenience to building owners. Remedial works to seal the leaking systems are hardly effective simply because the real leakage source is very hard to determine and sealing materials, such as sealant, can age. Dr. Wilson ZHOU has good experience in checking building failures (including water leakage). His experience plus his knowledge on curtain wall designs has enabled him to successfully determine water leakage sources for many projects. Remedial works proposed and carried out by capable contractors are found very effective.

Cracking sounds are often heard from curtain walls. Since curtain walls are used also on residential buildings recently, although such noises are usually of low sound levels (less than 55 dB), they are very annoying when the residents are sleeping and are awakened by such sounds. Remedial works are seldom effective because the sound sources are hard to determine and remedial works are not adequate. Dr. Wilson ZHOU has helped to solve such problems for various projects in Hong Kong. The results are satisfactory.

To avoid cracking sounds from curtain walls, the design for the curtain wall should take into consideration of this problem and should be carefully checked by a qualified curtain wall consultant.

    13. Personal Resume of Dr. Wilson Y.S. Zhou

    Dr. Wilson ZHOU graduated from Fudan University in Shanghai, P R China, and attained a Bachelor degree and a Master Degree of Science in Mechanics in 1982 and 1985 respectively. From 1985 to 1990, he worked in the Applied Mechanics Department at Fudan University as a teacher and subsequently promoted to a lecturer in 1987. During this period, he lectured and tutored several courses on Fluid dynamics, Mechanics of Materials, Calculus and Partial Differential Equations etc. He had also carried out research in the field of Biofluid Dynamics.

    In 1990, he left Fudan University to study for a PhD at the Centre for Building Studies, Concordia University in Montreal, Canada. He obtained fellowship awards from the Concordia University in two successive years of 1992 and 1993. He carried out Computer Simulation as well as Wind Tunnel tests to study the wind effects on buildings. He was awarded the PhD in 1995 for his success in the research.

    Dr. Wilson ZHOU became involved in the curtain wall industry in 1995 when he joined a curtain wall manufacturer. His responsibilities included structural calculations for curtain wall systems and management of curtain wall projects.

    Dr. Wilson ZHOU joined a leading curtain wall testing company in Hong Kong in early 1997 where he had the opportunity to see a lot of different curtain wall designs from the testing mock-ups which were built for performance tests based on their typical designs. Any failures of the curtain wall systems during the tests were analyzed and remedial works were witnessed and recorded in testing reports.

    In his role as a senior engineer and a general manager of this testing company, Dr. Wilson ZHOU helped the company to expand the testing business to various tests other than the curtain wall mock-up tests. He had also helped the company to expand the business into some new fields such as curtain wall consultancy, structural calculation and engineering design of curtain walls. He had carried out or instructed other engineers to carry out structural calculations, engineering design and OTTV calculations for curtain walls, window walls, glass walls, granite cladding systems etc.

    In January 2002, Dr. Wilson ZHOU established his own company - WILSON CURTAIN WALL CONSULTANT (HK) LIMITED.

    During his 23 years in the industry, Dr. ZHOU has conducted performance tests for more than 1500 projects on different building cladding systems. Tests were conducted to various international standards including ASTM, BS, AS/NZS and PR China's GB/T.

    Dr. Wilson ZHOU has inspected cladding failures on various buildings and provided remedial proposals. He has also helped cladding contractors to determine the wind pressures on buildings of different shapes and at different locations by using wind tunnel tests and/or the Hong Kong wind code.

    As a consultant for the Clients, Architects, Main (General) Contractors and Curtain Wall Subcontractors, Dr. Wilson ZHOU has checked, commented and approved as Independent Design Checker (IDC) the designs for curtain walls for more than 30 projects in Hong Kong.

    In the summers of 2001 and 2003 and in autumn 2009, Dr. Wilson ZHOU organized and gave lectures for a course on the design of curtain walls, glass walls, skylights, window walls, windows and stone claddings etc. More than 140 professionals in the building facade industry or academic attended the course. Course notes were prepared and distributed during the classes. Dr. ZHOU has also written and published a book on curtain wall design based on these course notes.

    As an engineer educated in Canada and China, Dr. Wilson ZHOU can understand both the western and the Chinese styles of doing business in both Hong Kong and Mainland China.
