How AJEC Compares to Other Energy Compliance Consultants

An honest look at the main options for Ontario home builders. We've included cases where a competitor may be a better fit — because the right match matters more than the sale.

Choosing the wrong energy compliance partner means failed inspections, missed rebates, and delayed closings. We want you to make an informed decision — even if that means pointing you elsewhere. Here's what we know about each option.

This is us
AJEC — A & J Energy Consultants
📍 Markham, ON — serving all of Canada

We specialize in OBC SB-12 performance path compliance and CMHC MLI Select energy modelling using HOT2000, primarily for Ontario production home builders running multiple subdivisions. With 315 subdivisions completed and over 25,000 homes evaluated, this is our entire focus.

Where we're different: we don't just deliver a report and leave. We provide on-site crew training and pre-inspection support so your team knows what inspectors are looking for before they show up. This is how we prevent failed inspections rather than respond to them.

Where we may not be the right fit: if you're building outside our core programs, pursuing Net Zero labelling as your primary goal, or need energy advisor training for your internal staff rather than compliance services.

Best for: Ontario production builders needing SB-12 or CMHC MLI Select compliance, with on-site support included.
Building Knowledge Canada
📍 Ottawa, ON & British Columbia

Building Knowledge Canada is primarily a training and certification organization for energy advisors. They offer courses, designations, and continuing education — their consulting services are secondary to this educational mission.

One practical difference for production builders: BKC does not provide on-site support after delivering a report. If your crew installs something incorrectly and the home fails inspection, resolving it is your responsibility. There's no pre-inspection visit or site training included.

Best for: Companies needing energy advisor certifications or building science training programs for their internal staff.
Worth knowing: No on-site crew training or pre-inspection support. Once the report is delivered, execution is on your team.
Homesol Building Solutions
📍 Perth, ON — serving 6 provinces across Canada

Homesol Building Solutions has been operating since 1999 and is one of the most established energy advisory firms in Canada. They serve builders across Ontario, BC, Nova Scotia, New Brunswick, Newfoundland, and PEI — a genuine strength for multi-province operations. They're recognized leaders in Net Zero Home labelling with 150+ certified projects.

Their national footprint and program depth make them a strong option if your scope goes beyond Ontario or if Net Zero certification is central to your brand.

Best for: Builders operating across multiple provinces, or those pursuing Net Zero Home labels as a market differentiator.
Clearsphere — John B. Godden
📍 East York, Ontario (Greater Toronto Area)

Clearsphere is led by John B. Godden — a veteran energy rater with over 35 years of experience, operating as a small boutique consultancy in the GTA. His specialty is HERS ratings and EnerGuide, working with production builders in Ontario.

John is genuinely credentialed: a RESNET conference speaker, founding board member of CRESNET, and a Qualified Net Zero Energy Advisor with CHBA/BILD. If you already know John, he's worth a conversation. There's no active website or public intake process — new clients come through referrals and existing relationships.

Best for: Builders with an existing relationship with John Godden, or those specifically seeking HERS ratings alongside EnerGuide.
Note: Small boutique team. No public website or online intake — new clients typically come through referrals.

Our Honest Take

Which option fits which situation

Choose AJEC if…
You're an Ontario production builder running multiple subdivisions who needs SB-12/ENERGY STAR or CMHC MLI Select compliance — and you want a partner who provides on-site crew training and pre-inspection support so failed inspections don't happen in the first place.
Choose Building Knowledge Canada if…
You need energy advisor training or certifications for your team, not on-the-ground compliance support for active subdivisions. They're educators first — if that's your need, they're the right call.
Choose Homesol Building Solutions if…
You build across multiple provinces and need consistent energy compliance coverage from Ontario to BC and Atlantic Canada. Or if Net Zero labelling is a core part of your product offering — they're the recognized leaders in that space.
Choose Clearsphere if…
You already have a relationship with John Godden and value his 35+ years of experience with HERS ratings and EnerGuide. He's not findable online — this is a referral-based engagement with a veteran in the field.
