8 Secrets Ontario Builders Use to Win Big on SB-12 Compliance
Over 90% of builders are overpaying for energy compliance — or boxing themselves into designs they don’t want. The SB-12 performance path unlocks 8 advantages most builders have never heard of.
Talk to Jack About Your Project →Over 90% of Ontario architects, designers, and builders believe prescriptive Package A1 is the easiest and most cost-effective way to meet SB-12. It’s not. This belief is costing builders hundreds of thousands of dollars in unnecessary upgrades, lost design freedom, and missed incentives — every single year.
The performance path isn’t more complicated. It’s just less well-known. Jack Zhou has been teaching these secrets to builders, designers, and building officials across Ontario since 2012 — and in that time, clients have skipped unnecessary triple-pane windows, eliminated continuous insulation requirements, removed DWHR units, and collected up to $100,000 in builder incentives. Here’s what the performance path actually unlocks.
The 8 SB-12 Performance Path Secrets
Build with any window-to-wall ratio — including 22%, 40%, or even 64%
Prescriptive SB-12 caps you at 22% window-to-wall ratio. Through performance modeling, you can design floor-to-ceiling glass, contemporary façades, and cottage-style fenestration and still meet code. Jack’s personal record: a 64% window-to-wall ratio cottage in Barrie.
Get U1.2 window compliance with zero cost premium
Window suppliers will charge you 15–35% more for "U1.2 equivalent" triple-pane or upgraded products. What they don’t tell you: an ER34 basic double-pane builder window is code-equivalent to U1.2. Same compliance, standard product, no premium.
Eliminate continuous insulation — above-grade AND below-grade
Say goodbye to R5ci on above-grade walls and R20ci on below-grade assemblies. Through performance trade-offs, continuous insulation can be eliminated entirely. For townhouses, this means studs right against the foundation — and 5–6 inches of recovered basement space.
Sell energy-efficient homes faster with higher margins
Combine the savings from secrets 3 and 6 to offer buyers a "finish-ready" insulated and framed basement as a premium upgrade. Your home is still code-compliant and more efficient than the reference building — and you charge more for it.
No HRV or ERV required (for townhouses & MURBs)
HRV is NOT mandatory through the performance path — exhaust fans can serve as your principal ventilation system. For back-to-back townhouses where venting every mechanical component is a space challenge, this is a game-changer. (Not recommended for detached homes.)
No Drain Water Heat Recovery units required
DWHR is a mandatory prescriptive requirement since December 31, 2016. Through the performance path, it can be eliminated. This isn’t a loophole — it’s explicitly allowed by the authority. Jack didn’t make it up; the Ministry confirmed it in writing.
Be $100,000 wealthier through the Enbridge builder incentive
If your homes are 15% more energy efficient than the OBC reference building (verified through energy modeling + blower door test), Enbridge will pay you up to $100,000 for 50 lots on your first entry. AJEC is an authorized Enbridge Gas service provider for this program. Spots are limited each year.
Future-proof your builds before mandatory airtightness testing arrives
The NBC is moving toward mandatory blower door testing. By 2032, all homes are targeted for net-zero ready standards (ACH 1.5 or lower). The performance path lets you leverage your airtightness score fully today — and positions your builds ahead of every coming code change.
Who This Is For
- Custom home builders with contemporary, cottage, or large-window designs that don’t fit the prescriptive path
- Production builders who want to pay per model type — not per house — and recover that fee in material savings
- Townhouse and MURB developers looking to eliminate HRV venting headaches and DWHR requirements
- Any builder who’s been told to "just upgrade to triple-pane" without being shown the ER equivalency option
- Builders interested in qualifying for the Enbridge $100,000 builder incentive program
How It Works
Send Us Your Plans & Specs
Share your architectural drawings, window specs, and envelope details. We confirm everything we need upfront — no chasing missing documents mid-project.
We Model Your Home Against the SB-12 Reference Building
Using HOT2000, we compare your design to the code reference house and find the most cost-effective compliance path — applying whichever of the 8 secrets apply to your project.
You Get a Stamped, Permit-Ready EEDS Report
A fully stamped Energy Efficiency Design Summary — exactly what your municipality needs to confirm SB-12 compliance at permit. Ready to submit, no rewrites needed.
Pre-Install Checks & Post-Construction Verification
Not sure if a product will pass? We check before it’s installed — at no charge. If a blower door test is required, we coordinate or conduct it and file the documentation.
Pricing
Straightforward pricing. Production builders pay per model type — one fee covers every unit of that design in your subdivision, whether you build 5 or 500.
Detached, Semi, Townhouse, Stacked
Full performance model, stamped EEDS, blower door test coordination, and one revision included.
- Design freedom from day one
- Pre-install spec checks at no charge
- All 8 secrets applied where applicable
$1,000 – $1,200 per home
Garden suites & tiny homes from $800
Single-Family Model Types
One fee per model type covers all units. Build 50 identical homes — pay once. Recover the fee in material savings on the first house.
- Unlimited units per model type

- Spec vetting before purchase orders
$300 – $500 per model type
Multi-Unit Residential Buildings
SB-12 performance compliance modeled per unique unit type. Efficient pricing for complex multi-unit builds.
- Energy model per unit type
- HRV elimination analysis included
- Permit-ready EEDS documentation
$300 per unit type
ℹ Post-construction revisions $200/hr | Additional blower door tests $350/test | Additional consultations $200/hr. Revisions are only triggered when installed specs fall short of what was modeled — products verified before installation at no charge. Use our pricing calculator →
This Isn’t the Right Fit If…
- Your design already meets prescriptive SB-12 without restrictions — modeling may not save you enough to justify the fee
- You’re looking for the cheapest number with no review, no vetting, and no coordination
- You want to proceed without sharing full architectural drawings and window specs — accurate modeling requires real data
- You’re building outside Ontario without discussing provincial code differences with us first
