Pass energy code. Avoid the redesign. Get to close on time.
AJEC handles energy compliance for Ontario home builders — so you never pay for a failed inspection, miss a rebate, or lose weeks to a code revision.
The Wrong Energy Strategy Has Real Costs
If you’re relying on the SB12 prescriptive path—or trying to figure out compliance on your own—here’s what that costs you:
❌ A failed energy audit can delay occupancy by weeks — and trigger $10,000–$40,000 in redesigns
❌ The prescriptive path locks you into upgrades you don’t actually need
❌ Most builders leave thousands in rebates unclaimed — because no one told them to look
❌ Poor energy performance means callbacks and complaints long after closing
❌ Every hour spent on code compliance is an hour away from your next project

We Know What It’s Like to Be in Your Boots
Juggling trades, inspections, client calls, and deadlines — and now you’re expected to be an energy code expert too? You shouldn’t have to be.
AJEC becomes the energy compliance arm of your team. We handle the modelling, documentation, and code strategy so you can stay focused on what you’re actually good at: building.
Our team is led by Jack Zhou — named Energy Advisor of the Year by ENERQUALITY — with 23 years of experience and 25,000+ homes assessed across Ontario.
Simply put, the A&J team is amazing to work with! With their outstanding technical experience and knowledge, they’ve been able to assist us during both our pre-construction and construction phases, as well as keeping our site superintendents and trades well informed.

We have had the pleasure of working with A&J for the past five years and have nothing but good things to say. The entire team is very knowledgeable and are great to deal with. Since working with A&J we have surpassed any of our expectations and have had quite a few homes test below 1.00 ACH (the gold standard for airtightness in Ontario’s new home construction).
