- 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.

2nd revised scheme B & scheme B’
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.

Star Garden High-rise Building Design
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.
