Energy and Green Mark Evidence
Use this guide when Facility Operations needs to support energy review, sustainability reporting, ESG preparation, or Singapore Green Mark evidence preparation. The workflow connects meter data, facility systems, Brick Schema or asset ontology relationships, documents, work records, inspection evidence, and customer-side review.
The output should help the facility and compliance team organize evidence, understand assumptions, and prepare review packages. Official certification strategy, submission, and assessment remain with the customer's appointed project and compliance owners.
Evidence Flow
Prerequisites
| Requirement | Why it matters |
|---|---|
| Evidence owner | Confirms review scope, evidence package, and external-use approval path. |
| Meter and system mapping | Connects readings to spaces, systems, equipment, and review periods. |
| Asset ontology | Explains relationships between spaces, meters, equipment, systems, and documents. |
| Source freshness | Shows whether readings, work records, inspections, and documents are current enough. |
| Assumption register | Records weather, schedule, occupancy, carbon factor, and simulation assumptions. |
Scope
| Review area | Typical evidence |
|---|---|
| Energy consumption | Meter readings, demand, normalized period, operating schedule, and source freshness. |
| Carbon-related review | Energy type, emission factors, reporting period, and calculation assumptions. |
| Equipment operation | Chiller, HVAC, lighting, IAQ, UPS, water, and other subsystem records. |
| Maintenance evidence | Work orders, inspections, repairs, setpoint changes, and commissioning records. |
| Document evidence | Drawings, manuals, SOPs, certificates, test reports, and owner approvals. |
| Green Mark clauses | Clause mapping, evidence item, gap dashboard, pack generation, and reviewer notes. |
Step 1: Define the Evidence Boundary
Confirm the boundary before collecting data.
| Decision | Example |
|---|---|
| Facility scope | One building, campus, tower, plant, or specific system. |
| Period | Month, quarter, retrofit period, handover period, or assessment cycle. |
| Meter scope | Whole-building meter, floor meter, tenant meter, system meter, or equipment meter. |
| System scope | HVAC, lighting, envelope, IAQ, water, renewable energy, or commissioning evidence. |
| Owner | Facility manager, ESG lead, Green Mark consultant, project owner, or compliance reviewer. |
Step 2: Map Spaces, Systems, Meters, and Equipment
Energy and Green Mark evidence is easier to review when relationships are explicit.
| Relationship | Why it matters |
|---|---|
| Meter measures space or system | Explains which area or load the reading represents. |
| Equipment serves zone | Connects HVAC, IAQ, or comfort evidence to affected spaces. |
| System feeds equipment | Helps explain upstream or downstream operational impact. |
| Work order affects evidence | Links maintenance actions to the operating period. |
| Document supports clause | Connects drawings, reports, or certificates to the evidence item. |
Brick Schema or another asset ontology can provide a consistent vocabulary for buildings, floors, rooms, zones, equipment, meters, and relationships. Use the asset ontology view to explain how records connect through reviewed relationships.
Step 3: Prepare Data Sources
| Source | Preparation |
|---|---|
| Meters | Confirm unit, interval, timestamp, meter-to-space mapping, and missing intervals. |
| BMS | Confirm point meaning, equipment mapping, setpoints, schedules, and alarm status. |
| Work orders | Link maintenance work to assets, systems, dates, and evidence files. |
| Inspections | Capture field checks, photos, notes, QR records, and reviewer status. |
| ECM | Organize drawings, reports, SOPs, commissioning records, and approvals. |
| DFS | Keep connector state, mapping, quality, lineage, and validation visible. |
Use Connect BMS Data to a Facility Twin and ECM Recipes for source preparation.
Step 4: Review Energy Assumptions
Energy outputs need clear assumptions.
| Assumption | Review question |
|---|---|
| Time window | Which period does the data represent? |
| Meter coverage | Which systems, spaces, or equipment are included? |
| Normalization | Are weather, occupancy, schedule, or production context needed? |
| Units and scale | Are units consistent across source and target fields? |
| Carbon factor | Which factor is used, and who approved it? |
| Missing data | How are gaps, stale readings, or estimated values marked? |
AI-assisted energy analysis can summarize profiles, anomalies, benchmark context, or carbon-related calculations when the input package is ready. Treat the output as engineering review input that must retain assumptions, source references, and reviewer notes.
Step 5: Use EnergyPlus-Oriented Analysis When Prepared
Some projects may prepare building simulation inputs for deeper review.
| Input | Review before analysis |
|---|---|
| Geometry and zones | Building, floors, zones, and envelope data are aligned with the facility model. |
| Materials and schedules | Assumptions are documented and approved by the project owner. |
| Weather and operation | Weather file, occupancy, equipment schedule, and operating mode are known. |
| Meter and system data | Source data is mapped, current, and traceable. |
| KPI target | The team knows which KPIs the analysis should produce. |
AI Engine can support KPI extraction, IDF input preparation, and EnergyPlus-oriented run workflows where project data is ready. Use the results as reviewed scenario input, with assumptions visible in the evidence package.
Step 6: Assemble Green Mark Evidence
Use the Green Mark workspace to organize evidence by clause and review state.
- Review active clauses and required evidence types.
- Map each evidence item to source modules, assets, systems, or documents.
- Upload manual evidence when approved by the project owner.
- Auto-collect available operational records where mappings exist.
- Review the gap dashboard for missing or stale records.
- Generate evidence packs for customer-side review.
- Record reviewer notes before external distribution.
The evidence pack should show source records, assumptions, owner review, and unresolved gaps.
Validation Checklist
- Scope, period, meter coverage, and owner are defined.
- Spaces, systems, meters, and equipment relationships are explained through asset ontology or reviewed mappings.
- Meter and BMS data include timestamp, unit, quality, and source freshness.
- Work orders, inspections, documents, and evidence files are linked to the correct context.
- Energy analysis shows assumptions and data gaps.
- Green Mark evidence packs are reviewed by the customer's responsible owner.
Failure Handling
| Symptom | Response |
|---|---|
| Meter coverage is unclear | Hold the evidence item for owner review and map the meter to the correct space or system. |
| Source readings are stale or incomplete | Show the gap in the evidence pack and request source correction or approved supplemental evidence. |
| Clause evidence is missing | Assign an evidence owner and record the missing item in the gap dashboard. |
| Simulation assumptions are incomplete | Keep EnergyPlus-oriented analysis in preparation until geometry, schedule, weather, and operating inputs are reviewed. |
