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.
