92 Overheating

To avoid exacerbation of the Urban Heat Island (UHI) effect, improve micro-climate conditions, and provide thermally comfortable environments, overheating will be prevented by:

A. Optimising the layout, orientation, materials, technology and design of new development to minimise any adverse impacts on internal and external temperature, reflection, overshadowing, micro-climate and wind movement;

B. Ensuring major development proposals follow the cooling hierarchy in alignment with the London Plan, considering future climate change;

C. Implementing adequate mitigation measures to minimise overheating, including landscaping, tree planting and the use of blue and green infrastructure; and

D. Ensuring all major developments undertake dynamic overheating assessments in line with Chartered Institute of Building Services Engineers (CIBSE) Technical Memorandum 59 (TM59) or equivalent.
