Green Mark Ratings: What Singapore Buyers Can Check Under v7.0

13 octobre 2026
Green Mark Ratings: What Singapore Buyers Can Check Under v7.0

A Green Mark rating is a certification issued by the Building and Construction Authority (BCA) that scores a building's environmental and energy performance against a national standard. Ratings run from Certified through Gold, GoldPLUS and Platinum, with the newer v7.0 scheme adding energy-only tiers (EE, SLE, ZE, PE). A higher band signals lower running costs, better occupant conditions and stronger positioning with tenants and buyers.

TL;DR:

  • Under v7.0, owners can pursue energy tiers from EE 45 through positive energy; sustained performance can extend certificate validity from three to five years.
  • Because Green Mark scores carbon, health, resilience, intelligence, and maintainability alongside energy, request the project scoresheet; two Gold buildings may qualify through different strengths.
  • GoldPLUS and Platinum nonresidential projects that use energy modeling must provide 12 months of actual operating data at Stage 2, so owners should plan early.
  • Before signing, verify the building’s rating and expiry date in the Green Mark directory, then request its current certificate from the landlord.
  • Certified commercial buildings in Singapore’s central business district have reportedly earned rents up to 12% above comparable uncertified properties, though results vary by building.

Green Mark tiers and the v7.0 energy-performance pathway

The original Green Mark bands remain in circulation across the building stock: Certified is the entry point, Gold and GoldPLUS sit in the middle, and Platinum marks the top-performing projects, each tier reflecting a minimum score against BCA's assessment criteria. Buildings that fall short of Certified simply do not receive a rating.

Green Mark v7.0 adds a separate, energy-only pathway that lets owners certify purely on measured energy savings rather than the full criteria set. The tiers under this pathway are:

  • EE 45, EE 50 and EE 55, reflecting rising minimum energy-savings thresholds for standard energy efficiency.
  • SLE 60 and SLE 70, the Super Low Energy tiers, which demand considerably deeper energy cuts.
  • ZE (net zero) and PE (positive energy), the highest tiers, reserved for buildings that offset or exceed their own consumption.

Certificates typically run for three years. Under v7.0, buildings that sustain their performance can qualify for an extended five-year validity, reducing the recertification burden for owners who keep delivering results.

What the Green Mark assessment covers: criteria and scoring structure

A Green Mark assessment is not a single energy audit. It scores a building across several linked categories, and the final rating reflects how well a project performs across all of them rather than excelling in one area alone. The main sections are:

  • Energy efficiency, including the Super Low Energy pathway for projects targeting deep energy cuts.
  • Whole-life carbon, covering embodied carbon in materials and construction alongside operational emissions.
  • Health and wellbeing, addressing indoor air quality, thermal comfort and daylighting.
  • Resilience, covering a building's ability to withstand climate and operational stresses.
  • Intelligence, assessing smart systems that monitor and adjust performance.
  • Maintainability, checking that sustainability features can be kept running over the building's life.

Certain requirements act as prerequisites: a project must clear baseline thresholds before it can be scored for advanced green efforts in other categories. BCA also publishes annexes within its Green Mark 2021 technical guides for specialised building types, such as healthcare facilities or data centres, where standard scoresheets do not fit.

Pro Tip: Ask for the project's scoresheet breakdown rather than just the headline rating, since two Gold-rated buildings can hit that band through very different combinations of criteria.

How certification and verification work

Certification follows a defined sequence, and understanding it helps explain why a rating takes months rather than weeks to secure.

  1. Application: owners apply digitally through the BCA Green Mark Online portal using CorpPass, specifying the building type, size and target tier.
  2. Fees: assessment fees vary by building type and floor area, with separate schedules for new applications and recertification.
  3. Stage 1 verification: BCA reviews submitted design documents and evidence against the chosen criteria.
  4. Stage 2 verification: for GoldPLUS and Platinum non-residential projects relying on energy modelling, this stage requires 12 months of actual operational energy data to confirm that modelled savings were achieved in practice.
  5. Recertification and portfolio options: owners with similar building stocks can pursue portfolio certification under v7.0, grouping multiple assets into a single process rather than certifying each separately.

Owners targeting the higher energy tiers should plan the 12 month measurement window well ahead of their intended certification date, since stage 2 cannot be shortened.

What a Green Mark rating means in practice: benefits and market impacts

For owners, a Green Mark rating is a lever BCA itself frames as a business strategy rather than a label, used to differentiate a building in leasing negotiations and tenant pitches. Certified commercial buildings in the CBD have reportedly commanded rents up to 12% higher than comparable uncertified stock, a gap that reflects both lower operating costs and the ESG signalling value tenants increasingly expect.

Investment payback on the underlying sustainability upgrades often falls within five to six years for some commercial retrofits, after which savings on energy and maintenance flow directly to the owner. Occupants benefit too, through better indoor air quality and daylighting captured under the health and wellbeing criteria. The extended five-year validity available to sustained performers under v7.0 adds a further practical benefit: fewer disruptive recertification cycles for buildings that keep their numbers up.

How to check a building's Green Mark status and quick examples from Singapore

Checking a building's status is straightforward. The Green Mark Building Directory and its open dataset on data.gov.sg list every certified project with its rating, certificate date and expiry, and flag whether it holds an SLE, ZE or PE designation.

When reviewing a listing, look for:

  • The rating band itself (Certified, Gold, GoldPLUS or Platinum).
  • Any SLE, ZE or PE flag, which indicates the v7.0 energy pathway was used.
  • The certificate and expiry dates, which show whether the rating is current or due for recertification.

The directory's exemplar entries include JTC Jurong Island DC, listed at Platinum, and The Gateway, listed at Platinum with SLE flags, both drawn from the published Green Mark dataset. For older commercial stock being upgraded toward certification, structural retrofit strategies are worth reviewing before assuming a building can simply be recertified at the same tier. Before signing a lease or offer, it is reasonable to ask a landlord or agent directly for the current certificate and its expiry date rather than relying on marketing claims.

When we assess a property's long-term value, we treat a Green Mark rating as one input alongside transaction history, rental yield and comparable sales data, not as a standalone score. Our Property Analysis tool lets you cross-reference a building's sustainability flags with its pricing trends, while our affordability checks help you weigh any rent premium against realistic running costs.

We recommend looking beyond the headline rating: check whether a building has kept up maintenance records and energy bills consistent with its certified tier, since a Platinum rating earned years ago is not proof of current performance.

Pro Tip: When comparing two similarly priced units, ask whether either building's Green Mark certificate is nearing expiry, since recertification timing can affect near-term service charges.

Short expert take on near-term market effects of Green Mark v7.0

The v7.0 energy pathway and portfolio certification option make it cheaper and faster for owners to certify or recertify, which should accelerate retrofit activity across older commercial stock over the next two to five years. Expect leasing and resale listings to lean more heavily on energy tier flags, particularly SLE and ZE, as that shorthand becomes a quicker signal than the rating band alone.

FAQ

What is Green Mark certification?

Green Mark certification is a rating issued by the Building and Construction Authority that scores a building's energy efficiency, carbon impact, health and wellbeing features, resilience and maintainability. A higher band, such as GoldPLUS or Platinum, indicates stronger performance across those criteria than a Certified-level building.

What are some examples of green buildings in Singapore?

The public Green Mark directory lists Platinum-rated examples such as JTC Jurong Island DC and The Gateway, the latter also carrying Super Low Energy flags under the v7.0 pathway. Both appear in BCA's open dataset with their certificate and expiry dates listed.

Is Singapore the greenest city?

Singapore runs one of the most established green building certification schemes in the region through Green Mark, with a stated target to green 80% of its buildings by 2030. Whether it qualifies as the greenest city overall depends on the measure used, and that broader ranking sits outside what Green Mark data itself establishes.

What are some conserved buildings in Singapore?

Conservation status and Green Mark certification are separate schemes: conservation protects a building's heritage features, while Green Mark assesses its environmental performance. A building can hold both designations, and checking the Green Mark Building Directory remains the most reliable way to confirm a specific conserved building's current certification status.

How do I check if a building still holds a valid Green Mark rating?

Search the building's name in the Green Mark Building Directory, which lists the current rating, certificate date and expiry date. If the certificate has lapsed, the building may no longer meet the standard it was originally rated against.
