The performance of external wall systems in tropical climates

Abstract Early failure in external wall systems of multi-storey buildings can incur high costs of maintenance and repair works. The prevention of rain penetration, the control of temperature changes, and resistance to pollution and climatic effects are vital requirements for achieving better performance. Imported technologies and materials are partially responsible for problems occurring but design, construction and maintenance processes also contribute. This paper presents a number of case studies specific to tropical climates to define common problems, determine particular causes and recommend suitable solutions.
