Description

BRANZ is monitoring sun, rain, wind and wind-blown sea salt in different positions on a building envelope. 

These conditions help to create a variety of micro-environments over the building that can be very different from the surrounding atmospheric environment.

This bulletin reports on the first monitoring of how micro-environments affect material performance on a BRANZ test building near Wellington.

Scope

This bulletin covers: 

• Testing and the test building
• Temperature
• Time of wetness
• Wind-driven rain
• Salt deposition
• UVA irradiation
• Corrosion rates of mild steel coupons
• Corrosion rates of mild steel nails in timber
