BCA-IDA Green Mark for Data Centres scheme comprises of a dedicated green building rating system for Data Centres (DCs) that is designed to encourage the adoption of energy efficient design, operation and management of data centres. The scheme is jointly developed by Building and Construction Authority (BCA) and IDA with supporting partners from Energy Research Institute @ Nanyang Technological University (ERI@N) and Lawrence Berkeley National Labs (LBNL) in the US.

Using the performance based green building rating system it is possible to score the impact of green policies, systems and processes that are implemented at the DC. Based on the total score of the DC a final rating (Platinum, Gold ^PLUS or Gold) is provided that is valid for a period of 3 years and has to be renewed thereafter.

The rating system covers performance efficiencies in areas such as energy, water and environment, with a significantly higher emphasis placed on energy performance of the DC. The scheme covers both existing data centres and new data centres and applies to data centres that are housed in purpose built buildings as well as those that occupy just part of a larger building. The details of assessment criterion and process that is applicable to existing data centres is available on BCA website at www.bca.gov.sg/GreenMark/green_mark_criteria.html . The assessment criterion for new data centres is slated to be launched in early 2013.

DCs that have been successfully certified under pilot run of BCA-IDA Green Mark for Data Centres are:
