  12. 12. HeatReady Cities Framework Mitigation Actions (make the city cooler and more comfortable) Green infrastructure Materials and coatings Waste heat Shade structures Water features Building geometry Air movement Adaptation Actions (help people cope with heat) Messaging and education Cool public places Cool homes Cool workplaces+ Reliable infrastructure Schedules and routes Social cohesion and support Internal Actions (support decision-making by city staff) Roles and responsibilities Visions and goals City plans External coordination Community input Data resources Capacity building Equity, Sustainability, and Institutionalization
