# IEQ 3.4 Thermal comfort - Shading - Non-Residential
# Applies to
All non-residential development
# Objective
To provide comfortable indoor spaces and reduce energy needed for cooling.
# Summary
Points are awarded where a minimum of 50% of east, west and north facing glazing (by area) to regular use areas has appropriate external shading.
Additional points are awarded where a higher percentage of glazing has appropriate external shading.
Maximum points are awarded where all east, west and north facing glazing has appropriate external shading.
# Documentation & evidence required
Reference to floor plans and elevations showing shading devices.
# Other Considerations
Fixed external shading to north facing glazing, such as overhanging eaves, can reduce excessive heat gain in summer while allowing warming winter sun to reach the glazing.
A variety of shading options are suitable for east and west facing glazing, including vertical shading structures such as adjustable louvres, as well as sliding screens, pergolas and roof overhangs, awnings and verandas.
