Applicants and architects should use this range of planning guidance and advice notes to promote good design.

Wind microclimate guidelines

These Guidelines (7MB) provide general advice on wind microclimate studies required as part of the planning applications for new development proposals in the City of London. They focus on the primary factors that affect the quality and consistency of wind microclimate studies. They are the first definitive guidance in the UK, reinforcing the City of London Corporation’s position at the forefront of this important planning issue.

Good wind microclimate conditions are necessary for creating outstanding public spaces in the City. Adverse wind effects can reduce the quality and usability of outdoor areas.

Developers are encouraged to address wind microclimate issues at an early stage in their plans by appointing experienced consultants, discussing with planning officers and commissioning early-stage studies to quantify the wind microclimate conditions.

Expert judgement by experienced wind engineer will always be needed for wind microclimate studies, particularly for issues that are not covered by these guidelines.
