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.
Energy modelling connected to real building conditions.
PWH combines energy-assessment work with hands-on HVAC and building-upgrade experience. That helps us challenge model assumptions before they become project problems.

Existing mechanical conditions
Usually, there is one decision holding the project up.
We do not begin with a generic report. We begin with the financing question, available building information and the decision your team needs to make.
Your financing team asked for energy modelling.
We confirm the building type, modelling pathway and information needed before you spend money on a report.
You need to know which upgrade path can reach the target.
We compare complete options—envelope, HVAC, DHW and ventilation—using the same baseline.
The result is close, and small assumptions could change it.
We show the assumptions, sensitivities and missing inputs so the team can act before submission.
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.
Design-stage review
First, we confirm the pathway and the missing information.
A short preliminary review helps avoid ordering the wrong model, using an inapplicable baseline or promising a result before the design is stable.
- Property type, location, unit count and storeys
- Existing building or pre-construction project
- Current or proposed HVAC, DHW and ventilation
- Drawings, utility information and design status
- Lender request, target and submission timing
