GM: 2021 Energy Efficiency

The Energy Efficiency section provides a set of harmonised, parallel routes for buildings to demonstrate their energy performance, from GoldPLUS through to Positive Energy Buildings. The levels are aligned for both new and existing building and complement our national commitments to carbon abatement within the built environment. The energy savings levels are a significant step up from previous versions of Green Mark. Projects are encouraged to look holistically at their energy systems from passive design solutions, active system efficiencies and right sizing, energy management and opportunities for renewable energy,

The GM 2021 Energy Efficiency section (EE) has been created leveraging our vast database of building energy performance, using AI calculation tools to ensure correlation between the standards, leveraging our work within the international community and refined through a collaborative approach with our Singapore Green Building Masterplan Taskforces. It is a data driven standard, that maps the longer-term vision towards super low energy and zero energy buildings. The approach is aligned and been an integral part of the development of ISO draft technical standard 23764 ‘Approach for non-residential Zero Energy Buildings’.

GM: 2021 is a key national lever under Singapore’s Long-Term Low-Emissions Development Strategy (LEDS) aligned to meeting our international obligations under the Paris Agreement, and part of an aggressive move towards the necessary climate action within our sector.

Green Mark 2021 Ecosystem

Green Mark Framework

[1] Mandatory requirements are based on development control and building plan provisions for new buildings, for existing buildings under retrofit, the requirements would vary depending on the type and extent of the works being undertaken.

Green Mark Certification

Project teams can choose either to follow the Green Mark Gold^PLUS or Platinum certification, or Green Mark SLE certification, or choose to do both by demonstrating world leading environmental asset performance.

GM Series	GM SLE Series
-	SLE, ZE, PE
Gold^PLUS	Gold^PLUS SLE/ZE/PE
Platinum	Platinum SLE/ZE/PE

Green Mark for Super Low Energy (SLE) buildings is an Energy (EE) focused series with robust holistic underpinnings from mandatory sustainability requirements through the national regulatory and policy system.

Energy Efficiency Pathways

GM: 2021 and GM: SLE use the same parallel pathways for projects to demonstrate their energy performance. The GM SLE Criteria groups these together in one place for each building typology. For buildings not covered, Pathway 3, Energy Savings would be the default compliance route. However, BCA could work with the project team on bespoke arrangements for the other pathways. Bespoke pathways will be updated periodically and will be made available.

The Green Mark Energy Pathways are:

Data driven and flexible – aligned to real project performance with validated data. Flexible routes for projects to demonstrate their performance.
Outcome based – full recognition of passive design strategies and renewable energy systems’ contribution to energy savings.
Supportive of innovation, encourage the use of new technologies, approaches and solutions to energy performance.

Pathway 1 – EUI

Total Building annual energy consumption over the gross floor area of the building (kWh/m² /yr). Based on:

Energy modelling (Design) for new buildings
Energy Calculation and measured data (for existing buildings with major retrofit)
Measurement – In operation

Additional Notes	New	Existing
AC Total System Efficiency (kW/RT)	0.8	0.9
Airside efficiency for buildings supplied by DCS/DDC/CCS (kW/RT)	0.2	0.25
Occupancy rate for EUI	100% (design)	≥60%
Renewable Energy included	On-Site

Pathway 2 – Fixed Metrics

Key performance metrics (ingredients) that make an energy efficient project. All aspects must be met individually.
Any shortfall in performance can be made up with the use of onsite renewables, subject to the building typology multiplication factor.
For projects utilising a District Cooling System (DCS), Distributed District Cooling (DDC) or Centralised Cooling System (CCS), the airside performance shall be used in lieu of Total System Efficiency (TSE) and shall be as follows:

Green Mark Certification level	Air distribution system efficiency requirement (kW/RT) For projects Using DCS/DDC/CCS
Gold^PLUS	0.2
Platinum	0.18
SLE	0.16

Pathway 3 – Energy Savings

Demonstrated energy savings following the Green Mark Energy Modelling guideline which looks at holistic energy performance against a reference model. This is the default pathway for projects not covered in Table 1A.

Additional Notes	New	Existing
AC Total System Efficiency (kW/RT)	0.8	0.9
Airside efficiency for buildings supplied by DCS/DDC/CCS (kW/RT)	0.2	0.25
Savings from onsite Renewable Energy	no cap
Savings from Passive Design	no cap

Green Mark EE Criteria

Certification Level	Requirement
Gold^PLUS	To achieve more than 50% of energy saving through adopting energy efficient measures and onsite renewable energy. Through demonstrating the stipulated performance through the relevant pathways indicated in Table 1A.
Platinum	To achieve more than 55% of energy saving through adopting energy efficient measures and onsite renewable energy. Through demonstrating the stipulated performance through the relevant pathways indicated in Table 1A.
SLE	To achieve at least 60% of energy saving through adopting energy efficient measures and onsite renewable energy. Through demonstrating the stipulated performance through the relevant pathways indicated in Table 1A.
ZE	Use of onsite and off-site renewable energy to generate at least 100% of energy needed for building operation, including all process/ receptacle loads. SLE performance shall be demonstrated. Off-site renewables can be used to offset the energy only where: SLE performance has been achieved through onsite measures. Onsite renewables have been maximised. Where the project is using REC's, these must be generated in accordance with SS 673: 2021 Code of practice for renewable energy certificates through renewable energy generated within Singapore. The length of time of REC commitment is minimally three years with commitment of re-certification
PE	Use of onsite renewable energy to generate at least 115% of energy needed for building operation, including all process/ receptacle loads. SLE performance shall be demonstrated.

Energy Efficiency Assessment

New Buildings under Design and Existing Buildings Pre-retrofit
All projectsshall demonstrate the stipulated performance through the relevant pathways indicated in Table 1A. Pathway 1 - Benchmark EUI (Table 1B and Table 1C), detailed measurement and calculation (Existing buildings) or energy model (new buildings) shall be used to calculate and justify the design EUI. Pathway 2 - Fixed Metrics, the prescriptive performance values shall be met in all areas. Where there is a shortfall of performance, this shall be annualised and required to be offset through onsite renewables with the listed multiplication factor. Detailed calculations, drawings and specifications would be required to substantiate the declared performance. Pathway 3 - Energy Savings, the energy modelling for evaluating the energy performance of a building shall be carried out in a prescribed mannerto quantify the potentialsavings based on energy efficiency measures and improvements that reduce cooling load requirement over the Reference Model. Projects are to refer to the BCA Green Mark 2021 Energy Modelling Guide for details. Note on Renewable Energy: During design or pre-retrofit stage, the expected renewable energy generated percentage and the total annual electricity consumption ofthe developmentshall be calculated. Technical productinformation ofthe renewable energy system and detailed drawings showing the location of the system shall be provided.


New Building Verification Stage and Existing Buildings in Operation
When the building has completed construction or its retrofit, a verification audit shall be carried out. For new non-residential buildings, there are two stages of verification. For existing buildings with commitment, only stage 1 verification is applicable. For Buildings in operation, not undergoing retrofit, the assessment would be based upon its operational data. Stage 1 Verification (New Buildings and Existing Buildings with Commitment): The Green Mark verification shall demonstrate the implementation of the design stage strategies and note any deviations and their effect on the ability of the project to achieve the energy performance. Stage 2 Verification (New Non-Residential Buildings): The building shall demonstrate compliance to the committed performance stated in the pathway using 12-months of measured data with a requirement of minimum occupancy of 60% for the period of measurement. Deviation of less than 5% for the Energy Savings from energy modelling is allowed, otherwise a calibration would be required. Note on Renewable Energy The generated renewable energy, using 12-month actual operation data, will be audited.
