Screen air quality impacts for planning applications using IAQM/EPUK guidance. Assess construction dust, operational emissions, NO2 exposure, and required mitigation measures.

For residential; set to 0 if non-residential
Distance from development to major road; <50m = higher risk

Total vehicle movements (both directions) per hour at peak
% of trips that are HGV/buses; typical range 2–8%
Total off-street parking; includes surface & multi-storey
Typical new build 12–24 months; demolition/excavation adds risk
