Design Strategies for the “Climate” variable

Migration

• Rooms & Courts organized so activities can take place in cooler areas during warm periods.

• Activities can also take place in warm spaces during cooler periods.

• People move from one space to another based on heating/ cooling needs & comfort

Layers of Shade

• Overhead shade protects the courtyard & building from high angle sun

• Vertical shades protect the building from low angle sun

Clustered Rooms

• Reduce skin area

• Reduce heat loss or gain

• Buildings with low skin/volume ratio have less radiation/heat leaving through their walls, windows and roof

• Can be a major advantage in the heating season.

• Usually requires a heat source (furnace, fireplace, etc.)

[Heating]

East – West Plan

• Increase winter sun facing skin (south facade)

• Main rooms open to the south with large glazing

Deep Sun

• Must effectively organize plans & sections

• For thicker buildings (2 or more rooms deep)

Tournai Primary School – Jean Wilfart

Stratification Zones

• Vertically zoned rooms in building to take advantage of temperature stratification

• Takes advantage of natural rising of hot air

[Heating + Cooling]



Buffer Zones

• Buffer rooms (that can tolerate temperature swings) located between protected rooms

Rooms that Face the Sun & Wind

• Increase effectiveness of solar heating and cross-ventilation

• As air flows around a building, it creates higher pressure zones on the windward side and lower pressure zones on the lee side.

• Inlets are placed on high pressure side, outlets on low pressure side to get cross- ventilation

[Heating + Cooling]

Kindred House – Anagram Architects



Direct Gain Rooms

• Open to collect the sun

• Store heat within a space

Thermal Storage Walls

• Collect and store heat at the edge of a room

• Sun passes through glazing (on south wall) and heats up the thermal storage medium

• The thermal storage medium in turn heats the space

• Masonry walls delay transmission of heat

• Water walls transfer heat more quickly

[Heating + Cooling]

Permeable Buildings

• Can combine open plans and open sections.

• Leads to cross-ventilation, stack-ventilation or a combination of both.

[Cooling]

Cross-Ventilation

• As air flows around a building, it creates higher pressure zones on the windward side and lower pressure zones on the lee side.

• Inlets are placed on high pressure side, outlets on low pressure side to get cross- ventilation

Stack-Ventilation

• Ideal for non-windy conditions when cross-ventilation won’t work

• Orientation independence (openings can be on any side of building)

• Warm air rises and escapes high in building, cold air replaces warm air from openings at the base of the building.

Wind Catchers

• Capture breezes above roof level for buildings whose windows have little access to breezes

• Independent orientation of wind catcher to building openings

[Cooling]

Qatar University – Kamal El-Kafrawi

Night Cooled Mass

• Thermal mass can be used to absorb heat from a room during the day

• The mass is then cooled at night with ventilation

[Cooling]

Evaporative Cooling Towers

• Supply cool air to rooms without the use of fans or wind

• Hot outside air passes through high inlets covered with a wet evaporative pad

• Air picks up moisture raising its humidity and lowering its temperature.

• Tower can be used for stack- ventilation if outside air temp is lower than inside temp

[Cooling]

Earth Edges

• Can shelter buildings from extreme heat or cold

• Increases the resistance to heat flow of walls, roof and floor

• Reduces temperature difference between inside and outside

• Can build into existing hillside, berm earth around building, or set building inside an excavation
