Whole-Building Energy Modelling and Compliance Reporting

Technical models and clear reports for Part 3 permit applications, Toronto Green Standard submissions, MLI Select and performance-based design decisions.

From drawings to defensible results

A coordinated model, not just a software output

Enerways can translate architectural, envelope, lighting and mechanical design information into a whole-building energy model and a structured submission package. The model is developed around the applicable code, municipal, lender or incentive methodology.

We use tools such as eQUEST and OpenStudio/EnergyPlus, selected according to the project and the accepting authority’s requirements. Toronto Green Standard Version 4 expressly lists eQUEST 3.64 or higher and EnergyPlus among accepted modelling options.

Typical deliverables
01

Baseline & proposed models

Whole-building simulations that compare a reference case with the proposed design and document the selected assumptions.

02

Performance metrics

Annual energy use, peak loads and applicable metrics such as TEUI, TEDI and GHGI.

03

Compliance documentation

Energy-efficiency design summaries, modelling narratives, calculation tables and supporting schedules required for the submission path.

04

Design coordination

Review of envelope, lighting, HVAC, service-water heating, schedules and controls with the project team.

05

Scenario analysis

Comparison of practical design options to understand how system and envelope choices affect performance.

06

Review responses

Model revisions and technical clarification during municipal, program, lender or third-party review.

Submission pathways
Building permit

OBC / SB-10 support

For new large residential or non-residential buildings and additions, municipalities may require documentation demonstrating compliance with the Ontario Building Code energy-efficiency requirements, including the applicable SB-10 path. We can support the model, calculations and report package for coordination with the project’s qualified designers.

Site plan & higher tiers

Toronto Green Standard energy reports

For Part 3 buildings over 2,000 m² GFA, Toronto’s Version 4 guidelines require a Design Development Stage Energy Report before Site Plan Approval to demonstrate Tier 1 performance. Projects pursuing higher tiers and the Development Charge Refund may also require an As-Constructed Stage Energy Report based on as-built or issued-for-construction information.

CMHC MLI Select

Energy simulations can support points for climate compatibility in eligible new and existing multi-unit projects. CMHC requires appropriate simulation software and documentation from a qualified professional; results are submitted through the approved lender’s application process.

Design & incentives

Option analysis and savings calculations

A calibrated or project-specific model can help compare HVAC, envelope, controls and electrification strategies, prepare defensible savings estimates and support applications where an incentive program requires engineered calculations.

Our modelling workflow
01

Confirm the compliance path

Identify the code, municipality, program, lender and project-stage requirements.

02

Collect design inputs

Review drawings, specifications, envelope assemblies, mechanical schedules, lighting and operating assumptions.

03

Build the model

Develop the reference and proposed cases in the selected modelling environment.

04

Quality-control the results

Check geometry, schedules, loads, unmet hours, energy balances and the consistency of baseline assumptions.

05

Prepare the report

Summarize methodology, inputs, performance metrics, compliance results and supporting calculations.

06

Support review

Coordinate revisions and answer technical comments within the agreed project scope.

Important project note

Requirements vary by jurisdiction and submission route.

Software acceptance, baseline rules, professional responsibility, signatures and required forms must be confirmed for each project. Enerways’ scope is defined around those requirements and coordinated with the architect, engineers and other qualified designers where applicable.
