Energy Assessment, Modelling & HVAC Upgrade Planning for Multi-Unit Buildings
We help owners of low-rise and small-to-mid-sized multi-unit buildings assess existing performance, compare mechanical upgrade options, and develop a practical implementation roadmap.
- Existing and new-construction MURBs
- Rental, mixed-use, affordable and co-op housing
- GTA and selected Ontario projects
Discuss Your Building
Share the basic property information. We will follow up to confirm whether an initial discussion is appropriate.
A building-level approach, not a one-equipment sales pitch.
Multi-unit buildings have connected mechanical, electrical, ventilation and operating constraints. A useful upgrade plan must consider how the building works today, what the owner is trying to achieve, and what can realistically be completed in phases.
PWH combines assessment and modelling capability with practical HVAC implementation experience. The objective is a clearer decision: what to upgrade, in what order, and what information is still required before committing capital.
Low-rise and small-to-mid-sized multi-unit buildings
A roadmap, not just a report.
Baseline findings, upgrade scenarios, energy and GHG implications, mechanical considerations, project risks, and a practical next-step plan.
From existing conditions to an upgrade decision.
The exact scope depends on building type and project stage. These are the three areas most projects need first.
Building Assessment & Energy Baseline
Review existing HVAC, domestic hot water, ventilation, envelope conditions, utility information and operating constraints.
Energy Modelling & MLI Select Support
Applicable HOT2000 or other accepted modelling, scenario comparison, energy and GHG results, and supporting technical documentation.
Mechanical Upgrade Roadmap
HVAC, heat pump, DHW and ventilation options, with electrical, installation, phasing and budget-level considerations.
Planning must reflect what can actually be installed.
The report is not the finish line. Where a project proceeds, PWH can support equipment selection, installation coordination, commissioning and project close-out.
Central or unit-level heat pump pathways
Domestic hot water system options and load impact
Existing conditions, code and upgrade coordination
Capacity, distribution and phasing constraints
Build the upgrade plan around the financial pathway.
For many multi-unit projects, the upgrade scope and the financing strategy must be developed together. PWH helps define the technical measures, model the expected results and organize the information needed for program, lender and advisor review.
CMHC MLI Select
Whole-building assessment, baseline and proposed modelling, upgrade scenarios, energy and GHG comparison, and technical documentation support for qualifying new or existing multi-unit projects. This work is most useful when considered before a purchase, refinancing or major capital commitment.
Save on Energy Retrofit Program
Identification of potentially eligible HVAC, heat-pump, control and other retrofit measures, with technical information organized for pre-project review where applicable.
Clean Technology ITC
Potential tax-credit treatment may be reviewed for qualifying heat-pump or clean-technology capital equipment. PWH can organize equipment and project information; final tax eligibility must be confirmed by the owner’s tax advisor.
Financing & Phasing
Upgrade measures can be grouped into immediate, near-term and later phases so owners can coordinate equipment replacement, available incentives, lender requirements and capital budgets.
Program rules and funding availability can change. Final eligibility, financing terms, incentive amounts and tax treatment are determined by the applicable program, lender and the owner’s professional advisors.
Tell us what you are planning, replacing or trying to verify.
An initial discussion can begin with the property type, number of units, current mechanical system and the decision or financing question you need to address.
