The $100 million Green Mark Incentive Scheme for Existing Buildings (GMIS-EB) scheme was first launched on 29 April 2009 which aims to encourage developers and/or building owners to adopt energy efficient retrofitting design, technologies and practices in their existing building to achieve a significant improvement in the building energy efficiency. BCA has enhanced this scheme which now provides:-

(a) A cash incentive for upgrading and retrofitting that co-funds up to 50% (capped at $3 million) of the costs of supply and installation of energy efficient equipment and professional services to improve the energy efficiency of existing buildings.

(b) A 'health check' , which is an energy audit to determine the efficiency of the air-conditioning plants. BCA will co-fund 50% of the cost for conducting this Health Check and the remaining 50% will have to be borne by the building owner.


The GMIS-EB Health Check scheme has expired. We are currently reviewing the scheme and will provide updates here subsequently.

The enhanced GMIS-EB cash incentive for upgrading and retrofitting has expired with effect from 28 April 2014. The funds for the enhanced GMIS-EB cash incentive are now fully committed.


In general, the GMIS-EB is applicable to existing building owners if their building meets the following criteria:

  • Existing private commercial (non-residential) developments.
  • Minimum gross floor area of 2,000 sqm.
  • Buildings must have central chilled water air-conditioning plants or which will be upgraded to have central chilled water air-conditioning plants.
  • Buildings must have attained a Green Mark rating which is still in its validity period preceding the application; or the Building owner must, at the time of application, have applied for Green Mark certification and the Green Mark assessment has not commenced or been completed, the Building owner must, at the time of application, be applying simultaneously for Green Mark certification in respect of the Building.

For the 'Health Check', the building owner must submit the application concurrently with the application for Green Mark certification.

All applications must be lodged before the start of the energy audit.

The scheme will not be applicable to buildings from the public sector as such projects have already being substantially funded by the government.


All Green Mark Incentive Scheme (GMIS) applications are to be submitted via BCA GMIS Online.
