| Definition: | Proposal of a guide to represent the solutions implemented to counter urban overheating, with some keys to map these solutions in a coherent way. |

Proposal
The idea for this proposal came from discovering an urban development intended to bring freshness to the city. This composite material structure turned out to be impossible to enter into the Openstreetmap database for lack of suitable tags.
This page is therefore mainly intended to identify existing tags, guide the contributor in the proper use of them and serve as a basis in the proposals for additional tags if necessary.

Rationale
Categories
'Green' and 'blue' solutions: nature, vegetation and water
'Gray' solutions: choice of urban materials
'Soft' solutions: limiting heat input from humans
'Urban form' solutions: bioclimatic (architecture and town planning)
