Beijing Star Garden
initial sketch for final
This project initially began as the site plan for
the Asian Games site in Beijing. With the collaboration with Tsinghua
University, we designed a strategy of low-rise high-density apartments.
Site ventilation was examined in detail. (See studies)
After market considerations and developer decisions,
the low-density scheme was dismissed in favor of a site plan consisting
of several towers ranging in height from 18 - 33 stories. MIT and
Tsinghua's task was to design four towers at the north of the site.
To minimize heat loss in the winter due to northern
winds, service functions such as bathrooms, stairs, and elevator
cores are placed to the north. To minimize circulation while promoting
natural ventilation, we implemented a circulation scheme consisting
of a skip-stop elevator service which stops every 3 floors, thus
creating a mix of duplex and single-story apartments.
Considerations are as follows:
Architectural Design Priorities
Reduce energy consumption
Improve air quality and ventilation
Create duplex apartments with
double-height spaces and floor-through apartments - maximizing
potential for natural ventilation
Design units to have 2 sides available for ventilation
Elevator stops every three floors - to the
circulation level of the cluster
Residents then can enter apartments at the circulation level
or take stairs to levels below and above.
Savings on capital and maintenance costs.
Divide building into separate cluster zones
of three stories within a high-rise apartment complex
Sixteen Units make up one cluster
Each cluster has a shared social gathering space.
Possible shared functions such as for laundry, mailboxes,
or place for children to play
Double-height atrium space functions as lobby and creates
landscaped terrace gardens in the sky
South-facing rooms must have
proper shading in the summer yet allow low-angled winter light
to pass through
Design at site level o to promote good
ventilation for each building
Understand 'microclimate' created at lower zone of building
Design the exterior form to signify 'green'

Climatic Design Priorities
Winter: · Keep heat in and cold temperatures
Protect from the cold winter winds.
Let the winter sun in.
Use natural ventilation to decrease need for dehumidification.
Intermediate season has to be stretched for minimizing energy
Keep the hot temperatures out.
Protect from summer sun.
Minimize solar gains.
