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.
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.
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.

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
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”
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
