Green Mark Scheme (GMS)

GMS for Buildings

CIOB Certification for Green Buildings

CIOB Green Mark is a green building rating system to evaluate a building for its environmental impact and performance. It is supported and accredited by the Building and Construction Authority of Singapore and endorsed by the Ministry of Construction & Housing and the Ministry of Mahaweli Development & Environment. It provides a comprehensive framework for assessing the overall environmental performance of new and existing buildings to promote sustainable design, construction and operations practices in buildings.

Under the assessment framework for new buildings, developers and design teams are encouraged to design and construct green, sustainable buildings which can promote energy savings, water savings, healthier indoor environments as well as the adoption of more extensive greenery for their projects. As for existing buildings, the building owners and operators are encouraged to meet their sustainable operations goals and to reduce adverse impacts of their buildings on the environment and occupant health over the entire building life cycle.

The assessment criteria cover the following key areas:

  • Energy Efficiency
  • Water Efficiency
  • Environmental Protection
  • Indoor Environmental Quality
  • Other Green Features and Innovation

The assessment process involves a pre-assessment briefing to the project team for a better understanding and evaluation of CIOB Green Mark requirements and the certification level sought. Actual assessment would then be carried out at later stage to verify the relevant reports and documentary evidences and that the building project meets the intents of the criteria and certification level.

The assessment identifies the specific energy efficient and environment-friendly features and practices incorporated in the projects. Points are awarded for incorporating environment-friendly features which are better than normal practice. The total number of points obtained will provide an indication of the environmental friendliness of the building design and operation. Depending on the overall assessment and point scoring, the building will be certified to have met the CIOB Green Mark Platinum, Gold, Silver or Bronze rating.

Certified Green Mark buildings are required to be re-assessed every three years to maintain the Green Mark status. New buildings certified will subsequently be re-assessed under the existing buildings criteria. Existing buildings will be re-assessed under the existing buildings criteria.
