Global Building Impacts
1. GB definition
What is a green building?
• Environmentally responsible and resource-efficient throughout their life-cycle.
• Designed, constructed and operated to reduce the overall impact on human health and the natural environment by:
Efficiently using energy, water, and other resources
Reducing waste, pollution and environmental degradation
Protecting occupant health and improving employee productivity
1. GB definition
• GHG Emission reduction potential
• Healthier working/living place
• Higher productivity
• Occupant Brand Value
• Lower operating costs
• Increased selling and renting value

What is a Green Building Rating Tool?
A framework for:
o benchmarking building performance
o encouraging integrated building design & construction
o raising awareness of „GB‟ benefits
o meeting legal obligations
o attaining resource security
o 3rd party verification of environmental credentials

In Vietnam
Industry:
• Wrong perception of GB cost premium
• Lack of technical/management skills
• Scarce “green” products
• Highly speculative market
Government
• Insufficient regulation & law enforcement
• Insufficient guidance & lack of incentives
• Highly subsidised energy cost
Users:
• Lack of clear demand from end users
3- GB development triggers and obstacles
What drives green initiatives in Vietnam?
• MNC corporate guidelines
• Financial long term benefits of investors/operators
• Sales and marketing considerations
• Implementation of more stringent EE and environmental codes
• Increasing awareness of global environmental issues

GB development in South East Asia
A growing interest and substantial development since 2009. Mainly through voluntary systems run by non for profit organisations. This global momentum has been coordinated through the World GBC platform. Only in Singapore and China, government has been leading GB development. Recently IFC introduced EDGE, a resources efficiency tool, to address social housing and other lower end construction segments.

Life Cycle Cost analysis
20
Viewed over a 30 year period: Initial building costs account for approximately just 2% of the total, while operations and maintenance costs equal 6%, and personnel costs equal 92%. O&M costs = 2 X cumulated design and construction costs. This clearly illustrates the importance of planning and running operations at an optimised level.
