• Architects Intentions:
I want not to create together
I want not to create beams
I want not to create walls
I want not to create room
I want not to create architecture
• Flexible and adaptable space
• Main concept ‐ Plate, Tube, Skin
Concept
Location
• Interaction with immediate surroundings
• Dense urban context
• Relatively low rise surrounding buildings
• Little overshadowing
• Building orientated on East‐West axis
• Secondary areas to the north
• Frequently used public and open areas to the south
Level +5

Secondary areas
Passive Design Strategies – Orientation & Organization
Passive Design Strategies – Acoustic barriers
• Double skin façade to reduce noise pollution
• Vegetation acting as a natural acoustic barrier
Double Skin Facade • Used for passive ventilation
purposes
• Thermal blanket – trapping air
Passive Design Strategies – Ventilation
Passive Design Strategies – Ventilation
Tubes • Tubes used natural ventilation
• Active climate control system
Active ventilationsystem Passive ventilation system
• Lightwells
• Free façade
• Sunlight tracking system
• Lighting characteristics based on function
Passive Design Strategies – Daylighting
• Double Skin
• Reduction in solar gain
• Thermal barrier
• Artificial Acoustic barrier
• Glass fins used to retain transparency
and maximise daylighting
Thermal Passive Design Strategies – Double skin façade (South)
West Facade
The west side facade, which faces another plot, is
opaque, coated with a metal frame that reveals the
emergency stairs
Thermal Passive Design Strategies ‐ Solar Shading
Thermal Passive Design Strategies ‐ Solar Shading
East Facade
The east facade of the building has a series of different
facade finishes depending upon use inside the building.
These finishes give a different quality to the daylight inside
each floor.
Construction Techniques – Roof (Ventilation)
•
•
• Secondary non‐structural roof
• Photovoltaic panels
• Defines overall building height
• Used for natural ventilation purposes
• Honeycomb structure disrupting wind flow
Constuction Technique ‐ The Tubes
• Tubes acts as key structure for the building
• Tubes contain all vertical circulation
• Allows for natural ventilation
• Tubes as lightwells
• Free organisation – tubes as part of the space
Q3. What design steps might be used in order to integrate these passive design strategies into your design practices?
Construction techniques to adopt – Multifunctional columns
Daylighting Vertical Circulation MEP Structure
• Structural
• Vertical circulation
• MEP Services
• Daylighting
Advantages:
• Insulation against temperature extremes
• Acoustic Barrier
• Control of solar gain
• Increased glazing area to maximise daylight in
the building
Construction techniques to adopt – Double skin facade
• Lightweight structure • Optimised building height for earthquake
proofing • Damping mechanism – absorbs 70 percent of
seismic energy.
Construction techniques to adopt – Future proofing for earthquakes
• Allows for lean design
• Optimise design solutions for maximum
occupant comfort
Construction techniques to adopt – Parametric design
