Beijing Star Garden

initial sketch for final design scheme

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 of buildings
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

Minimize circulation

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 zone.
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' building

Climatic Design Priorities

Winter: Keep heat in and cold temperatures out.
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 consumption.

Keep the hot temperatures out.
Protect from summer sun.
Minimize solar gains.
