Tropics
the earth is divided into:

4. Philippines
•Longitudinal lines
( 114°-127º east )
•Latitudinal lines
( 4°-18.5°north )

5. Climate
Encompasses the stats of temperature, humidity, atmospheric particle count.
Weather
Present condition of these elements and their variations over shorter periods.
Annual mean temperature
given approximately by the average temperature of the maxima and minima for the warmest and coolest months

6. Climatic factors
•Latitude
•Temperature range increases with distance from the
equator
•The sun rays are dispersed over a large area of land as you
move away from the equators
•Polar regions are colder because the sun rays have further
to travel compared to place on the equator.

7. Climatic factors
•Altitude
•Temperature decreases with height
•Air is less dense and cannot hold heat
1500 meters above sea level high altitude
3000 meters very high altitude
5000 meters extreme altitude
8000 meters death zone

8. Climatic factors
•Winds
•Hot winds high temperature
•Cold winds low temperature
❖Prevailing winds
•Southwest monsoon (habagat) (warm, humid)
•Nortwestmonsoon (amihan) (cold, dry)
Habagat Amihan
-May -November
-June -December
-July -January
-August -February
-September -March
-October -April

9. Climatic factors
•Continentality:
❖As the distance from the sea increases, people experience extreme
weather conditions, i.e., very hot during summers and very cold
during winters. This condition is known as continentality.
❖Land heat and cools faster than the sea.
❖On the coast winter are mild and summers are cool.
❖Because of its high heat capacity, water can minimize
changes in temperature. For instance, the specific heat
capacity of water is about five times greater than that of
sand.

10. Climatic factors
•Aspects:
❖Slopes facing the sun is warmer
❖Air temperature are cooler when morning sun shines
❖Air temperature are warmer when afternoon sun shines

11. Climatic factors
•Solar Radiation:
❖Warms the air over the Equator, causing it to rise

12. Climate
❖MicroClimate–localized climate that
surrounds the building
❖Mesoclimate–(intermediate geographic
scale)
-influenced by physical characteristics
of a local area (terrain, hills, vegetation, )
example Baguio.
❖Macro Climate –regional climate , 10-
100km+

14. Season in the Philippines
Dry season –Dec. to May
▪Cool dry season –Dec. to February
▪Hot dry season –March to May
Rainy season –June to Nov.
❖Tropical Cyclone -Storm system
characterized by a large low pressure center
and numerous thunder storms that
produce strong winds and heavy rain.
❖Typhoon and Hurricane –Defending on
its location and strength.
PAGASA
The Philippine Atmospheric, Geophysical and Astronomical
Services Administration.
The major services provided by PAGASA include the provision of
weather forecasts and tropical cyclone warnings, flood bulletins
and advisories, hydrological, climatological and farm weather
forecasts.

15. Passive Cooling
Design of building interiors without the use of sophisticated mechanical equipment, but rather with a use of principle and techniques of
tropical design.
Passive Cooling Techniques:
Stack effect
Building OrientationUse of windows

16. Passive Cooling
Passive Systems For Various Climates
Hot-Humid Climate Hot-Dry Climate Temperate Climate Cool Climate
maximum wind exposure minimum radiant heat gain moderate thermal retention maximum thermal retention
maximum internal airflow moderate wind resistance moderate radiant heat gain maximum radiant heat gain
minimum radiant heat gain moderate internal airflow slight wind expose (humidity control) minimum wind resistance
moderate internal airflow

17. Principle of Airflow
1. Air flows from a high pressure to a low-pressure area
2. Air possesses inertia. Once set in motion it tends to continue to flow in its initial direction until some intervening force is
met.
3. Air flows through the path of least resistance

18. Global Air Movements
1.Air flows to the cooler arctic from the warm equator
2.Surface movement is from the cooler region to the warm coast

19. General Circulation of Winds
1.The rotation of the earth deflects the air from its direct paths, (Coriolis Force)

20. Land and Sea Breezes
1.Land and sea breezes
