The Energy Efficiency section provides a set of harmonised, parallel routes for buildings to demonstrate their
energy performance, from Gold
PLUS
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, demonstrating world leading environmental asset performance.

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/m
2
/yr). Based on:
• Energy modelling (Design)
• Energy Calculation and measured data (Retrofit)
• Measurement – In operation

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 the airside performance shall be used in lieu of Total
System Efficiency (TSE) and shall be as follows:

EE >50%
Platinum EE ≥55%
SLE EE ≥60%

Pathway 3 – Energy Savings

energy performance against a reference model. The default pathway for projects not covered in Table 1A.

Energy Efficiency Assessment
New Buildings under Design and Existing Buildings Pre-retrofit
All projects shall 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 off set 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 manner to quantify the potential savings 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 of the development shall be calculated. Technical product information of the
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
Buildings in operation, not undergoing retrofit, the assessment would be based upon its operational data.
Stage 1 Verification (New Buildings): The Green Mark verification shall demonstrate the implementation of
the design stage strategies and note any deviance from these and their effect on the ability of the project
to achieve the energy performance.
Stage 2 Verification and Existing Buildings in operation: The building shall demonstrate compliance to the
committed performance stated in the pathway through 12-months measured data with a requirement of
minimum occupancy of 60% for the period of measurement. The Energy Savings from energy modelling
would require deviance less than 5% else a calibration would be required.
Note on Renewable Energy
the generated renewable energy, using 12-month actual operation data will be audited.
Note for Zero Energy Buildings
The building shall demonstrate compliance to the committed 100% net replacement through onsite and/or
off-site renewable sources.
Note for Positive Energy Buildings
The building shall demonstrate compliance to the committed 115% net replacement through onsite
renewable sources.
