Problems with building envelopes:

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

On-site check on the tempered glass to find out the glass of a high-risk of spontaneous breakage is always a dream to many building users. Wilson Curtain Wall Consultant (HK) Limited has used 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 to curtain walls or windows is a very headache problem to building owners. Remedial works to seal the leaking systems are hardly effective simply because the real leaking source is very hard to determine. Dr. Wilson ZHOU has good experience in building failure (including water leakage) inspections. His experience plus his knowledge on curtain wall designs has enabled him to determine successfully water leakage sources.

Cracking sounds are always heard from curtain walls that are more popularly used nowadays on residential buildings. Such noises are usually of low sound levels (less than 55 dBs) but are very annoying when the resident is 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 sound 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. To give a requirement of “no cracking sound is allowed” in the specification for the curtain wall is not enough to avoid this problem.

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

Dr. Wilson ZHOU graduated from Fudan University in Shanghai, P R China, and attained Bachelor degree and Master degree of Science in Mechanical Engineering 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 fellowships 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 include: structural calculations of 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. The failures of the curtain wall systems during the tests whenever happens 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 wall, window wall, glass wall and granite cladding systems etc.

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

During his 17 years in the industry, Dr. ZHOU has conducted performance tests for 1000 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 on cladding failures to 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 20 projects in Hong Kong.

In the Summer of 2001, 2003 and in the Autumn 2009 respectively, 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 this 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 and marketing business in both Hong Kong and Mainland China.
