- Climatic Design PrioritiesWinter: 1) Keep heat in and cold temperatures out.

2) Protect from the cold winter winds.

3) Let the winter sun in.

Spring: 1) Use natural ventilation for dehumidication./Fall 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

Star Garden High-rise Building Design

  Problems  - North wing units do not receive

enough southern light.- Privacy compromised betweennorth wings.

- Building plan exposes too muchsurface to outside, increasing heatloss.

- Too compact unit plan creates

poor natural ventilation withinunits.

- Symmetry of plan does not considerlocal climate conditions.(ie. west sun,north winds)

  Improvement  - More compact design decreases

exterior surface area.- Improvement of natural

cross ventilation.- Privacy provided between

north wing units.- Interior south-facing areasincreased for apt units.

- Sequential hierachy of spaces inunit plan.

  Features:  - A more compact form decreases

surface area of the building. Thisgreatly reduces heat loss thruexterior walls.

- Service core at north of buildingbuffers residences from winterwinds.

- 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 andact as buffer spaces in winter.

  Features:  - Building is divided into 5-story

cluster configurations.- Each cluster contains a common

space for ventilation. This commonspace allows for natural ventilationof building in temperate seasonsthru the stack effect.

- Each unit has both south-facing

bedrooms & living areas.- Living areas contain sunspaces that

meditate extreme outdoorconditions.

- Roof garden absorbes heat gainfrom roof.

- Cross ventilation possible thru eachunits.
