Architect - Shifting of Design Paradigm
• Recently :
– Design iconic, unique, monumental building
– Focus on esthetics, function, room organization
• Shifting to :
– Responsibility on climate change
– First step - building envelope  energy
– Cooling load and natural lighting
What Next ??
Should they perform the same?
NEW ‘Green’ Buildings
EXISTING Grey Building
New Building vs Existing Building
New Building :
Existing Building :
• Start from “zero”
• “Grey” building - is fixed
• Design
• Operation & Maintenance
• Promise
• Improvement
• Most on “paper”
• Actual Performance
• Fill-in the gap
• Energy, Water & Indoor Air
Quality
• Transform the practices
• Continuity from NB
The gap
Regulation
Implementation
Design
As Built
Promise
Achieved
Non-standard Based
Standar based
Building Industry Player
• Still digesting about green concept
• Green label as a marketing tools
• Less concern of green performance.
Green Building Concept
• It is not only a technology or engineering issue
• Nor a trend,
• It is a change of :
– mindset
– behavior,
– a way of life
– culture
• It is a future
GLOBAL FUTURE TREND
TODAY, sustainability is . . .
TOMORROW, it is . . . . . . .
• Nice to have
• MUST HAVE
• An area of interest
• A mandate for action
• A project in individual
building
• A strategy for an entire
portfolio
• A business case to
justify
• A standard & code
