MURB Energy Roadmap & CMHC MLI Select Modelling
Building-level baseline, upgrade scenario comparison, energy and GHG modelling, and a prioritized decision roadmap for multi-unit owners, developers and financing teams.
Ontario projects · Existing buildings and pre-construction
A dedicated decision tool for an owner’s next capital step.
This page focuses on the planning and modelling deliverable—not the full range of MURB assessment, installation and ongoing HVAC services.
Retrofit or Repositioning
Compare practical upgrade bundles before major HVAC replacement, refinancing, acquisition or phased capital work.
Pre-Construction Roadmap
Test the intended design path early, while envelope, HVAC, DHW, ventilation and electrical choices can still be adjusted.
MLI Select Pathway
Organize baseline and proposed modelling, energy and GHG results, assumptions and supporting information for financing discussions.
From building facts to a finance-ready action plan.
The exact scope is confirmed by building type, available records, project stage and the decision the owner needs to make.
Roadmap Stage
Work Included
Decision Output
1 · Scope & Inputs
Confirm property type, unit count, project stage, current systems, available drawings, utility information and the owner’s decision question.
Agreed modelling and assessment scope.
2 · Building Baseline
Establish the existing or code-reference baseline using confirmed assumptions and the applicable modelling pathway.
A defensible starting point for comparison.
3 · Upgrade Scenarios
Develop two to four coordinated bundles covering envelope, HVAC, DHW, ventilation, controls and relevant electrical constraints.
Comparable options—not isolated equipment choices.
4 · Energy & GHG Results
Model scenario performance and compare energy use, GHG reduction, assumptions, sensitivities and material risks.
Clear evidence of which pathways are worth advancing.
5 · Priorities & Phasing
Sequence measures into immediate, near-term and later phases around replacement cycles, design needs and capital timing.
A practical order of work and next-step list.
6 · Decision Package
Summarize the selected pathway, key results, limitations and information required for lender, consultant or project-team review.
A financing-ready roadmap and follow-up discussion.
The value is in comparing complete pathways.
A boiler replacement, suite heat-pump conversion, DHW change or envelope measure cannot be assessed in isolation when the building systems interact. The roadmap compares coordinated bundles using the same baseline and assumptions.
- Existing-condition or code-reference baseline
- Two to four realistic upgrade bundles
- Energy and GHG impact
- Installation and electrical constraints
- Phasing, risk and information gaps
The objective is not to force the highest theoretical result. It is to identify a pathway that is technically credible, financially relevant and practical to advance.
What the roadmap does—and what follows afterward.
Included in the Roadmap
- Building and project-scope review
- Applicable baseline and energy modelling
- Upgrade-bundle comparison
- Energy and GHG results
- Assumptions, sensitivities and risks
- Prioritized roadmap and decision summary
Normally Required Later
- Detailed engineering and permit documents
- Final contractor quotations and procurement
- Authority, lender or CMHC approval
- Installation, commissioning and close-out
- Final attestation where applicable and only after the design pathway is confirmed
Program rules, reference baselines and documentation requirements may change. Final eligibility and financing decisions remain with the applicable lender, CMHC, program administrator or authority.
