BU563 Building on exposed sites (2013)

This bulletin outlines some important factors that should be considered when designing and constructing buildings on sites that are exposed to high winds. As wind speeds and the loads generated are higher, traditional practices may not be sufficient to prevent a building from structural or envelope damage or leaking.

This bulletin replaces Bulletins 405, 406, 407 and 408.

The bulletin covers:

• the effect of high wind on buildings
• design considerations, including collecting site-specific data, mitigating wind effects, structural design, weathertightness, insulation and ventilation
• exposed coastal sites
• working on windy sites.
