Green Buildings and Super Low Energy Buildings

Green and Super Low Energy buildings reduce usage of energy, water and materials while improving indoor environmental quality for better health and wellbeing.

What BCA is doing to promote green buildings

Our national target is to have at least 80% of buildings in Singapore to be green by 2030. We are running multiple schemes and programmes to create a greener built environment in Singapore, including:

 Scheme/Programme  About

A programme for students in Institutes of Higher Learning (IHL) to help their alma mater schools attain Green Mark certification.

 BCA-SGBC Behavioural Change Programme   

A programme developed by BCA and the Singapore Green Building Council to help building occupants and end-users adopt sustainable habits and reduce environmental impact.

Super Low Energy (SLE) buildings
