2. Macro climate: The climate of a larger area such as a
region or a country
Micro Climate: The Variations on Localized climate in or
around a building
In the built environment we are concerned with the local environment
systems because the macro and micro climate have a very important
role to play in the energy performance of a building.

7) Encourage Heat Loss Through Conduction
7. Increase ventilation by cool breezes.
Replace hot air next to building wall and roof with cooler air.
8. Reduce surface temperatures in prevailing wind directions
•Prevent
infiltration of hot
winds.
•Reduce wind
speed.
• Deflect Hot
Winds.
•Insulate Building.
9. Increase rate of evaporation.
Increase evaporative surfaces
Increase convection over evaporative surfaces.
10. Block incident radiation to ground surface
Trap air cooled by evapo-transpiration next to ground surface.
Reduce conductivity of ground.
11. Expose building walls and roof to cool conductors.
Trap air cooled by evapo-transpiration next to building walls
and roof.
12. A building or landscape design should exploit the
maximum number of complementary-design strategies
for passive cooling.
There are seven types of landscape and building
elements: walls, windows, screens, roofs, canopies,
floors, and courts.
