Organised by the Singapore Green Building Council, the IGBC was held from 9 - 12 October 2012 at Sands Expo & Convention Centre Marina Bay Sands, Singapore. The theme is "Green Community. Green Action".

Held alongside BEX Asia 2012, the IGBC 2012 had brought together the growing international network of green advocates to share in a series of green building activities and knowledge shring platforms. Governments, industries and consumers around the world were becoming increasingly aware and were responding to concerns about the effect of carbon dioxide emissions on climate change by designing more energy-efficient and environmental practices and regulatory regimes.The global movement has to go beyond buildings - to reach, touch and galvanise the community and the individual.


Organised by the Building and Construction Authority (BCA), IGBC 2011 was held from 14 - 16 September 2011 at Suntec Convention Centre, Singapore with theme of "Build Green. Act Now".

Sustainable Construction Exhibition


BCA organised a 3-week exhibition on Sustainable Construction from 23 April to 11 May 2007 at the URA Centre, in conjunction with the Singapore Structural Steel Society. The aim of the exhibition was to raise awareness on the importance of moving towards sustainable construction.

Besides information on posters, there were exhibits to showcase various building components that employ sustainable construction, emphasising that sustainable construction need not be bland and creativity could be enhanced. Examples include a curved steel structure showing the metal cladding and the flexibility of steel structures, another exhibit showing different types of steel panels including those used in the latest HDB lift upgrading projects, a cross-section of a drywall to show its interior structure, and samples of recycled materials and products.

The exhibition included three multimedia containing general information on sustainable construction with the statements of support from industry stakeholders, and highlighting the benefits of drywalls in residential projects with testimonials from homeowners and developers.

The exhibition was also displayed at Republic Polytechnic and Ngee Ann Polytechnic for the past few months.

Seminar / Conference
Special Talk on Sustainable Construction

Two prominent experts, Professor Roger Plank from University of Sheffield and Professor Richard Liew were invited to speak at the Talk.

Conference on Recycling for Sustainable Construction

Sustainable Construction is the adoption of building designs, construction methods and materials that enhances the resilience of our construction industry.

Through recycling, more materials can be readily reused for the same or similar purpose, thereby reducing both waste and burden on our environment. In this conference, local and overseas speakers from Japan, Hong Kong, United Kingdom shared on the waste management plan, development of policies in recycling and the latest technologies in sustainable construction. The potential of these technologies was discussed to give participants a good appreciation of how such recycling techniques can impact our construction industry.
