BU620 Managing wind effects around buildings (2018)

Reducing the impact of wind at a site improves the micro-climate around the building, reduces wind loads on the structure, improves energy efficiency by reducing heating demands and gives an improved, safer living environment. Wind impact can be reduced by the siting, layout and shape of buildings, planting, fences and screens and reshaping of land forms. 

This bulletin replaces Bulletin 321 Reducing the impact of wind at building sites. 

This bulletin covers: 

• the nature of airflows
• site analysis
• site planning
• building design 
• fencing
• planting
• modifying landforms.
