3. 1. PURPOSES OF CLIMATE MAP
Definition
◦ The concept of UCMapping was first developed by German
researchers in the late 1970s(Matzarakis, 2005).
◦ Urban Climatic Map integrates urban climatic factors and
town planning considerations. It provides an information
platform to planners for making informed environmental/
planning decisions.
4. 1. PURPOSES OF CLIMATE MAP (Cont)
Purposes
◦ To understand principles of climate and to define
information of climate for an area/ region;
◦ To have better urban planning;
◦ Respect natural conditions and environment
◦ Urban Climatic Map integrates urban climatic factors and
town planning considerations. It provides an information
platform to planners for making informed environmental/
planning decisions.
5. 2. KEY PRINCIPLES (INPUTS)
Two main UCmap components:
◦ UC-AnMap (Analysis Map): visualizes and spatializes
various climatic evaluation and assessment by different
Climatopes.
◦ UC-ReMap (Planning Recommendation): includes
planning instructions from the urban climatic point of view.
Parameters
Wind directions and speeds
Solar radiation
Air temperature
City topography
Landscape
Building bulks
Street grids
Etc,

9. 3. ANALYSIS THE CLIMATE MAPS OF HCMC
1 Fresh & cool air production zones
2 Cool air production zones.
3 Mixed & transitional climate zone
4 Overheating potential zone
5 Overheating zone 1
6 Overheating zone 2
10. 3. ANALYSIS THE CLIMATE MAPS OF HCMC
Green colours mean cold air production with downstream drainage
or fresh air with or without relief energy
The light green and orange areas are mixed zones which can be
warm during day but are able to cool down at night
The red colours indicates areas with more risk of heat accumulation.

13. 4. CLIMATE MAP & PLANNING
“Place which requires an improvement”
“Place which should be conserved”
14. 5. RECOMMENDATION
Guidelines of using climate map;
Properly study climate in planning City;
Collaborate with related organization for the best results;
Raise the awareness of climate importance;
Planners should consult urban climatologists to interpret
UCMap and planning instructions appropriately
