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,

8. 3. ANALYSIS THE CLIMATE MAPS OF HCMC

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.

 “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
