Climactic Design Properties

Winter:
1) Keep heat in and cold temperatures out.
2) Protect from the cold winter winds.
3) Let the winter sun in.

Spring/fall:
1) Use natural ventilation for dehumidication
2) Intermediate season has to be stretched for minimizing energy consumption.

Summer:
1) Keep the hot temperatures out.
2) Protect from summer sun.

Comparison between original design and proposed alternatives

Original Block Plan and First Revised Scheme A

Problems
- North wing units do not receive enough southern light.
- Privacy compromised between north wings.
- Building plan exposes too much surface to outside, increasing heat loss.
- Too compact unit plan creates poor natural ventilation within units.
- Symmetry of plan does not consider local climate conditions.(ie. west sun, north winds)
Original Block plan  
Improvement
- More compact design decreases exterior surface area.
- Improvement of natural cross ventilation.
- Privacy provided between north wing units.
- Interior south-facing areas increased for apt units.
- Sequential hierachy of spaces in unit plan.
Scheme A  

 

Second Revised Scheme B and Scheme B'

Features:
- A more compact form decreases surface area of the building. This greatly reduces heat loss thru exterior walls.
- Service core at north of building buffers residences from winter winds.
- Each apt. has both south-facing bedrooms & living areas.
- Living areas contain sunspaces that mediate extreme outdoor conditions.
- Deep closable niches between units provide ventilation in summer and act as buffer spaces in winter.

Scheme B Section - A through sunspaces
Schem B' Elevation & Section - B through niches

 

5 Unit Scheme A

Features:
- Building is divided into 5-story cluster configurations.
- Each cluster contains a common space for ventilation. This common space allows for natural ventilation of building in temperate seasons thru the stack effect.
- Each unit has both south-facing bedrooms & living areas.
- Living areas contain sunspaces that meditate extreme outdoor conditions.
- Roof garden absorbes heat gain from roof.
- Cross ventilation possible thru each units.

South Elevation

 

5 Unit Scheme B

Features:

- 2 floors / elevator stop (skip-stop).
- Maximum southern exposure.
- Minimum north expsure.
- Service core north-west buffer.
- Natural ventilation for common space.
- Avoids west exposure.
