In the initial phase, the proposed regulatory requirements to meet minimum Green Mark Standards will apply to the following building types with gross floor area (GFA) exceeding a certain minimum area specified and to the installation/replacement of the building cooling systems of a specified minimum capacity: a.

PROPOSED REGULATORY MEASURES TO RAISE ENVIRONMENTAL SUSTAINABILITYSTANDARDS FOR BUILDINGS
Proposed Minimum Green Mark Standards for Buildings undergoing Installation/ Replacement ofCooling Systems
Who will be affected?
In the initial phase, the proposed regulatory requirements to meet minimum Green Mark Standards willapply to the following building types with gross floor area (GFA) exceeding a certain minimum areaspecified and to the installation/replacement of the building cooling systems of a specified minimumcapacity:a. Hotel;b. Retail buildings; andc. Office buildingsIt is expected that up to 1,000 buildings will be included in the initial phase.
ObjectiveOne of the targets of the Sustainable Singapore Blueprint was for 80% of Singapore’s buildings toachieve Green Mark certification by 2030, of which improving the energy efficiency of existing buildings
was key.
The installation/replacement of the building cooling system is an extensive and costly building work. It isthus timely and important for building owners to relook at their existing building design and makeimprovements to the other parts of the buildings as well to achieve even greater energy savings in futureyears.
Proposed Legislative DetailsBCA will require buildings which intend to install/replace their building cooling systems to comply withGreen Mark (Existing Buildings) (GM(EB)) standards at Certified level (i.e. 50 points).
The owners of these buildings must engage a consultant to look into the overall building design, propose
necessary retrofitting measures, meet GM(EB) standard at the design stage and submit the design andthe score to BCA.

Annex B
Proposed Legislative DetailsBCA will require owners of the following building types to conduct three-yearly audit on their buildingcooling systems. This will ensure that the buildings, after being designed with efficient energyperformance, will continue to be operated efficiently.a. Buildings which have undergone retrofitting to comply with GM(EB) standards; andb. New hotels, retail buildings and office buildings with centralised chilled-water building coolingsystem which are required to comply with the enhanced Green Mark standards for new building
implemented on 1 December 2010.
A consultant must be engaged to conduct the audit.
The above measure has minimal cost impact as building owners would have put in place permanentinstrumentation when they retrofit their buildings to meet minimum GM(EB) standards. Theinstrumentation installed will allow them to monitor their cooling system efficiencies in a cost-effectivemanner.
Compulsory audits on the other aspects of the building (e.g. lighting system, water fittings and wastemanagement systems) will not be necessary.

Annex B
Proposed Mandatory Report on Annual Building Energy Consumption
Who will be affected?It will affect both building owners (excluding owners of industrial buildings or dwelling units) and utilitysuppliers. However, the data will primarily be obtained from the utility suppliers. This will drasticallyreduce the need for building owners to submit the data individually and separately to BCA.
ObjectiveThe data will form the basis of the national energy benchmarks, which BCA will share with buildingowners so that they can pro-actively improve their buildings’ energy performance. With the availability ofthe data, BCA will also be able to monitor energy consumption patterns and measure the effectiveness ofvarious initiatives that have been adopted to improve energy efficiency.
Legislative DetailsThe proposal will require the submission of electricity consumption data of all buildings (excludingindustrial buildings and dwelling units) on an annual basis. Primarily, such information will be obtainedfrom the utility suppliers. This will drastically reduce the need for building owners themselves to submitthe data individually and separately to BCA.
The proposal will also require owners of buildings (excluding industrial buildings and dwelling units) toprovide basic building information such as the gross floor area (GFA), building activity and buildingsystems (e.g. air-conditioning and lighting systems). This will be conducted in phases starting withcommercial buildings (office, hotel and retail buildings). BCA will also approach owners of selectedbuildings for more detailed information to support a comprehensive study on energy efficiency of thebuilding stock.
ConsultationBCA will be consulting the industry on the details of the proposals over the next few months.
