`Coral-Team 2001Spring Presentation Decision Matrix
Solution Pros Cons
SMRF Simple Design, symmetricFlexible, Central Circulation Quick to erect
CantileverNo reference to the locationCost more than EBF
EBF Core Lateral Load PathFlexible, Central Circulation More connection
Details, CantileverNo reference to the location Cost less
Shear Wall Core
Utilizes Stair-wellArrangement of the rooms analogous to utilization Easy material accessibility
Accidental TorsionRequire additional formwork
Timber
UnexploredArrangement of the rooms analogous to utilizationCost less when space is small
Fear of the unknownNot good for big space, need consider life cost

Specifications2. Facade
Why Sun Blocker
•Save energy on cooling loads
•Most of the heat is gained through the external façade.
Comparing:
Reduce the windows
Vision glazing
Reflective coating
Tint to the glass
`Coral-Team 2001Spring Presentation
Specifications
2. Facade
•Inflexible solar shading from aluminum lamella with different incline angles.
•Laminated coatings: vinyl films are used to provide nonmetallic color and long-lasting finish, and won’t aggregate heat in surrounding area.

Specifications3. Interior lighting
The lighting system
• Passive solar design (daylighting)
• Sensor systems that balance artificial light levels with the ambient light available
• High-efficiency fluorescent lamps and electronic ballasts
• Load monitoring and controls systems
• Automatic shut-off devices

Mechanical HVAC Systems
•Ventilation
•Air conditioning system
Objective:
•Take advantage of mild coastal air.
•Operable windows
•Thermosiphon design
•Underfloor supply plenum
• No ozone-depleting chlorofluorocarbon (CFC) refrigerants.
•Ease of access for maintenance, redundancy / back-up
`Coral-Team 2001Spring Presentation
Mechanical HVAC Systems•Underfloor Plenum
Plenum --------a large air supply or air return space.
A plenum system is based on air pressure (supply) or vacuum (return).

Looking Ahead and BehindBehind
We all did a good job of informing each other when work would be done and then sticking to it
MSN Messenger is a great tool
Switzerland is 9 hours ahead of PST
AheadMore communication with work done
More interaction with Mentors/Owners
A tighter work schedule
3D/4D models
Lessons Learned
Communicate and Plan EARLY
