Securing BCA GMIS-EB 2.0 Subsidies for Haze, IAQ, and Ventilation Upgrades

When transboundary haze returns, Facility Managers (FMs) and Building Owners find themselves facing a capital expenditure wall. Retrofitting aging mechanical systems to handle heavy smoke, installing high-efficiency filters, and deploying active indoor air quality (IAQ) monitoring can quickly cost hundreds of thousands of dollars.

However, the Building and Construction Authority (BCA) provides a massive, under-utilised financial lifeline: the S$63 million Green Mark Incentive Scheme for Existing Buildings 2.0 (GMIS-EB 2.0).

For qualifying commercial, institutional, and industrial assets, GMIS-EB 2.0 provides up to S$1.2 million or 50% of qualifying retrofit costs. Instead of absorbing the capital hit for critical air-side, filtration, and BMS upgrades, you can heavily offset these costs through government co-funding.

Understanding Outcome-Based Subsidies
GMIS-EB 2.0 is not a passive grant; it is strictly outcome-based. The payout you receive is tied to the Green Mark rating your building achieves post-retrofit.
To unlock the maximum co-funding tier of S$1.2 million (or 50% of eligible costs), the retrofitted asset must demonstrate extensive, sustained energy savings and target a high-performance standard, such as Green Mark Platinum Super Low Energy (SLE).

The Baseline Trap: Many FMs initiate upgrades first and attempt to claim subsidies later. BCA will disqualify claims for any work started or contracts signed before the formal grant application is approved.
The Energy Balance Requirement: Modifying fan speeds, adding physical filtration ( $\Delta P > 120\text{ Pa}$ ), or adjusting outdoor air intakes alters the building’s Energy Use Intensity ( $\text{kWh/m}^2/\text{yr}$ ). To ensure you don’t lose your existing Green Mark certification (or miss grant performance targets), any air-quality upgrade must be balanced with energy-saving measures, such as chiller plant optimization.

Step-by-Step Grant Capture Strategy

Step 1: Diagnostic Assessment & Verification of Energy Use Intensity (kWh/m²/yr)

Step 4: Award Retrofit Contracts & Install Energy-Efficient Air Triage Upgrades

1. Formally Verify Your Baseline
Conduct a comprehensive, non-invasive diagnostic energy audit of your central chiller plant and air-handling circuits. Document your current Energy Use Intensity ( $\text{kWh/m}^2/\text{yr}$ ) and indoor Air Quality (IAQ) baselines to establish a verified performance “before” photo for BCA’s assessment.

2. Scope eligible IAQ and HVAC Upgrades
Detail the precise technologies you need to combat haze and maintain building health. The grant typically covers:

High-efficiency primary air unit filtration (e.g., electronic air cleaners, low- $\Delta P$
electrostatic or MERV 13 banks).

Automated Demand Control Ventilation (DCV) and BMS sensors to regulate fresh air dampers based on outdoor $\text{PM}_{2.5}$ and indoor $\text{CO}_2$ levels.

Active air-scrubbing and UV/bipolar ionization systems inside PAHUs.
Variable Speed Drive (VSD) and fan motor upgrades to reduce the energy penalty of increased static pressure.

3. Submit Your BCA Application Before Starting Work
Bundle your energy modeling, engineering scopes, predicted savings, and financial projections into a formal submission. Secure BCA pre-approval before signing any vendor agreements. Once BCA issues the Letter of Offer, your co-funding is locked in, and physical works can begin.

Secure Your Government Funding Before Upgrading
Don’t forfeit your eligibility for up to S$1.2 million in direct cash grants. Let ES Management engineer your IAQ upgrades and secure your BCA GMIS-EB 2.0 approvals before you contract equipment vendors.
