In Singapore’s highly regulated built environment, compliance with building energy efficiency standards is not optional—it is mandatory. One of the most critical requirements for new developments and major retrofits is the submission of EPSS (Energy Performance Submission System) to BCA. Many building owners, consultants, and facility managers struggle with incomplete documentation, system integration gaps, and last-minute rejections. This is why having a clear and structured EPSS submission checklist in Singapore is essential.
At Smart Touch Technology, we support developers, consultants, and building owners with a complete EPSS submission Singapore solution, including system readiness, data preparation, and compliance support aligned with BCA requirements. Learn more about our EPSS solution here:

What Is EPSS Submission in Singapore?
EPSS (Energy Performance Submission System) is a mandatory submission to the Building and Construction Authority (BCA) of Singapore. It verifies that a building’s energy-related systems—such as HVAC, lighting, and controls—are designed, installed, and configured to meet BCA’s Green Mark and energy efficiency standards.
EPSS submission typically applies to:
- New building developments
- Major additions and alterations (A&A works)
- Buildings seeking Green Mark certification
A complete EPSS submission requires accurate system data, proper BAS integration, and verifiable performance documentation.
Why an EPSS Submission Checklist Is Critical
Avoid Rejection and Resubmission
Incomplete or incorrect submissions are one of the most common reasons for EPSS rejection. A checklist ensures nothing is missed.
Save Time and Cost
Late corrections can delay TOP/CSC approvals and increase consultant and contractor costs.
Ensure BCA Compliance
A structured checklist ensures alignment with current BCA EPSS technical requirements.
Improve System Readiness
EPSS is not just paperwork—it validates real system performance and integration.
EPSS Submission Checklist Singapore: Key Components
Below is a comprehensive EPSS submission checklist Singapore that building owners and consultants should follow.
1. Building Automation System (BAS) Readiness
EPSS requires verified data from the Building Automation System.
Checklist:
- BAS fully installed and commissioned
- All relevant HVAC systems connected to BAS
- Sensors (temperature, flow, pressure, energy) calibrated
- Real-time monitoring operational
- Historical data logging enabled
A compliant BAS is the foundation of successful EPSS submission.
2. Energy Metering and Data Accuracy
Energy data must be accurate, traceable, and verifiable.
Checklist:
- Electrical submeters installed and labeled correctly
- Chilled water meters calibrated
- Energy data mapped correctly in BAS
- Meter readings consistent with design intent
- Data export capability for EPSS platform
Incorrect energy data mapping is a common EPSS failure point.
3. HVAC System Information
HVAC systems represent the largest energy load in most buildings.
Checklist:
- Chillers, AHUs, FCUs fully listed
- Equipment capacities and efficiencies documented
- Control strategies configured (scheduling, reset logic)
- Operating parameters aligned with BCA requirements
- Sequence of operation (SOO) available
4. Lighting Control and Power Density
Lighting performance must comply with BCA efficiency limits.
Checklist:
- Lighting power density (LPD) calculations
- Zoning and scheduling details
- Occupancy and daylight sensors installed (if applicable)
- Lighting control integrated with BAS (where required)
5. Control Strategies and Setpoints
EPSS evaluates how systems are controlled—not just installed.
Checklist:
- Temperature setpoints defined
- Scheduling implemented and active
- Automatic shutdown during non-operational hours
- Demand-based or load-based control logic documented
- Alarm and exception handling enabled
6. Documentation for EPSS Submission
EPSS submission requires proper technical documentation.
Checklist:
- System architecture diagrams
- Equipment schedules
- Control logic descriptions
- Metering layout drawings
- BAS screenshots and data samples
All documents must match the installed system exactly.
7. System Testing and Verification
BCA expects systems to be functional—not theoretical.
Checklist:
- Functional testing completed
- Trend logs captured and reviewed
- Energy data verified over required duration
- Faults resolved before submission
- System stability confirmed
8. EPSS Platform Data Entry
Once systems are verified, data must be entered accurately into the EPSS platform.
Checklist:
- Correct building and project details
- Accurate system classification
- Energy values entered correctly
- Supporting documents uploaded
- Internal review completed before final submission
Common EPSS Submission Mistakes to Avoid
- BAS installed but not fully integrated
- Energy meters not mapped correctly
- Missing or inconsistent documentation
- Control strategies not activated
- Rushing submission without verification
A proper EPSS checklist helps eliminate these issues early.
