Comparison Table
GridPoint
enterpriseBuilding energy management software for monitoring, controls, diagnostics, and efficiency programs.
ECM and reporting templates tied to interval-based baseline workflows reduce analyst rework across many facilities.
GridPoint is geared toward commercial building auditing where interval-meter data and standardized normalization improve audit consistency across facilities. The system supports constructing an energy baseline, running measure assumptions, and producing audit reports that align with common client reporting expectations for site energy and emissions summaries.
A key tradeoff is that governance and data preparation discipline matter because high-quality interval imports and consistent metadata drive calibration stability and reporting accuracy. GridPoint fits best when a portfolio team needs repeatable audit production with shared templates, faster ECM turnarounds, and controlled review cycles for client deliverables.
- +Interval-data driven audit workflow for consistent cross-site baselines
- +Repeatable ECM development and audit report generation
- +Portfolio oriented configuration for standardized deliverables
- +Analysis outputs map cleanly to capital planning narratives
- –Interval data quality gaps can cascade into calibration variance
- –Report customization requires careful template setup discipline
- –Advanced workflows can add operational overhead for admin teams
- –Some integration paths depend on specific importer formats

Best for: Fits when portfolio energy teams need interval-data audits with controlled, repeatable report delivery.
IESVE
enterpriseBuilding performance simulation software for energy audits, retrofit analysis, and compliance studies.
Calibrated energy model workflow ties utility data reconciliation to scenario simulation and audit documentation outputs.
Commercial teams use IESVE when audits need consistent physics-based modeling rather than spreadsheet-only calculations. Core workflows center on simulation setup, load and comfort calculations, and scenario management across building systems. Model outputs can be translated into audit documentation with structured assumptions and result summaries.
A key tradeoff is that the workflow depends on correct model setup and input data quality, which increases effort when teams lack engineering support. IESVE fits best when an organization already manages interval meter data, weather normalization assumptions, and building system definitions, and needs repeatable outputs for multiple audits.
- +Calibrated energy model workflows support audit-style scenario comparisons
- +Simulation run management enables systematic ECM screening across alternatives
- +Structured reporting links outputs to modeling assumptions for repeatability
- +Strong engineering focus suits complex building systems and schedules
- –Model setup overhead is high for teams without energy modeling experience
- –Automation depth varies by workflow and may require template discipline
- –Import and reconciliation for utility interval data can be time intensive

Best for: Fits when engineering teams need repeatable calibrated modeling and audit reporting from simulation outputs.
Energy Elephant
SMBEnergy management software for utility data collection, analysis, reporting, and audits.
Audit-to-report generation keeps ECM inputs, assumptions, and results connected across the review cycle.
Energy Elephant guides teams through an end-to-end commercial audit process with structured inputs for site energy modeling inputs and ECM definitions. Audit reports are generated from that same structured work, which reduces retyping and mismatched figures during review cycles. The workflow also supports typical utility bill and interval-data import patterns used for normalization and load analysis.
A key tradeoff is that deep customization of calculations can require configuration discipline instead of fully free-form spreadsheet edits. Energy Elephant fits best when organizations need repeatable audit outputs for capital project prioritization and standardized client deliverables, rather than one-off analysis work.
- +Audit workflow links assumptions to measures and report outputs
- +ECM documentation reduces version mismatch during reviewer edits
- +Template-driven report generation speeds client deliverables
- +Interval-data and bill normalization inputs support consistent analysis
- –Advanced custom calculations need configuration discipline
- –Less ideal for teams that rely on fully manual spreadsheet workflows

How to Choose the Right Commercial Energy Audit Software
We separate options in commercial energy audit software by how each one handles audit-ready reporting, data input fidelity, and model transparency. The biggest differences show up when you test energy-baseline behavior and the way ECM outputs turn into a final audit-ready report.
Audit-ready report templates
Why it matters
Audit-ready report templates matter because teams need consistent deliverables across buildings and reviewers. If the outputs don’t match your internal format, rework can erase time savings.
How to check
In a demo, ask for a complete sample audit report from uploaded building info through the final PDF or export. Check whether sections, charts, and assumptions can be edited without rebuilding the workflow.
Utility data import handling
Why it matters
Utility data import handling matters because the audit’s credibility depends on what happens to missing, partial, or messy usage data. Strong import reduces guesswork before you build the energy baseline.
How to check
Run a sample upload with at least one gap and one meter/account mismatch. Verify whether it flags issues, how it treats missing periods, and whether you can review imported interval-meter data.
Weather and normalization options
Why it matters
Weather and normalization options matter because results can shift when assumptions change between seasons. The energy baseline output should reflect a clear, repeatable approach.
How to check
Request a side-by-side run with the same data using different normalization choices. Then inspect whether the degree-day adjustment and related settings are visible in the audit trail.
ECM assumptions traceability
Why it matters
ECM assumptions traceability matters because reviewers need to see why each energy conservation measure change leads to new savings. If the chain of inputs to outputs is hidden, capital project prioritization becomes hard to defend.
How to check
Pick one example ECM and open the full assumption view behind its savings results. Confirm you can edit key inputs, see the resulting energy balance change, and export assumptions for documentation.
Provisions, RBAC, and audit logs
Why it matters
Provisions, RBAC, and audit logs matter because multiple roles often touch the same audit package. Without clear governance, revisions can’t be trusted during review cycles.
How to check
Ask the admin demo for role setup and a protected workflow where analysts and reviewers act differently. Then verify you can view an audit log of edits tied to specific projects.
API and automation exports
Why it matters
API and automation exports matter because teams frequently connect audits to downstream workflows. Extensibility reduces manual re-entry and helps keep audit-ready report content consistent.
How to check
Ask for example endpoints or export formats for audit outputs and assumptions. Check whether you can automate updating project records and regenerating the audit-ready report from the same configuration.
Red flags
- Reports look editable but assumptions can’t be traced or exported
- Missing or mismatched utility data is silently corrected without an issue list
- Normalization choices are hidden or don’t show clear degree-day adjustment settings
Fit by situation
- If you run audits across many facilities with frequent reviewer edits, prioritize audit-ready report templates.
- If you inherit imperfect utility histories, prioritize utility data import handling.
- If you need to rerun savings with controlled assumptions for governance, prioritize ECM assumptions traceability.
