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.

4.  1) Prevent Heat Gain Through Radiation
 2) Encourage Heat Loss Through Radiation
 3) Prevent Heat Gain Through Convection
 4) Encourage Heat Loss Through Convection
 5) Encourage Heat Loss Through Evaporation
 6) Prevent Heat Gain Through Conduction
 7) Encourage Heat Loss Through Conduction

5. Block incident radiation.

6. Avoid reflected radiation and emitted radiation

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.

13.  plant wall
 planted berm wall
 peat moss wall
 planter wall
 stepped wall
 stepped planters
 tree/shrub wall

14.  window planter
 window planter wall

15.  tree screen
 balcony edge
 bris soleil planter
 freestanding planter screen
 vine-covered wall
 vine-covered lattice
 vine-covered cables
 detatched lattice
 sliding wall planter
 sliding window planter
 hinged planter screen
 pivoting screen/trellis

16.  roof lattice
 turf roof
 roof garden
 trellised roof garden
 glazed planter roof

17.  tree canopy
 freestanding trellis
 attached trellis
 fixed window shade
 sliding window planter
 pivoting screen/trellis

18.  plant floor
 unit pavers in grass
 grass pavement

19.  shade court/sun pocket
 hinged planter screen

20. Evergreen trees retain green foliage all year round.
