`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 illuminium

The conductance(C) of the Isulating-board backed aluminum is 0.55

Comparing:

Plastering Materials (Sand aggregate)11.10

Architectural glass 10

Wood, with insulating backer board, 0.71

Concrete blocks, (sand and gravel) 1.4

Lightweight aggregate 4in 0.67


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


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


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
