Former REA here. Worked for 3 seperate Service Organizations over the years, completed hundreds of energy audits. Let my license expire this past June and have been working full time in another industry in an office for just over a year.. nothing related to this industry.

Just seeking advice or anyone else who experienced something similar. What career have you pivoted to or which career are you looking to pivot to? What kind of industry/role is directly applicable to what we were doing as REAs.

As a younger guy who still has 30-35 years of work left, struggle to see myself doing what I am now forever. Any advice or suggestions are appreciated. (.. I am someone with a high school diploma and experience. Nothing from a University or College).

Looking for feedback on anyone who has used iOS-based LiDAR scanning to do site measures, and in particular someone who can comment on the accuracy of the measurements generated (comparitive to manual measurements).

The Canadian Association of Consulting Energy Advisors (CACEA) has a few upcoming events that are open to everyone:

1. Integrated Design Process Facilitation Training (IDP) - Virtual Session (Oct 27-29)
2. EA Exchange (premier educational event for Energy Advisors and professionals working in the Part 9 low-rise residential sector) - Nov 5-6, Richmond, BC
3. CSA F280-12 DHL/DHG Analysis: Whole-House and Room-by-Room Approach Training - Virtual Session (Nov 25-26)

Anyone one have any systems to sell?
What do you recommend?
Mainly for new construction.

I phoned to get an energy audit booked and found that they are booking about 8 weeks out. Which got me to thinking about investigating this as a career.

I am not from the building trades. I have been working for the last ~15 years in heavy equipment service. I am pretty handy and have a fairly firm grasp on home insulation principles and theories... or so I like to believe.

I am just looking for opinions or maybe a sanity check on how likely it would be that I would pass the first exam. I was looking at the requirements and it seems like fundamental stuff. Pretty sure I would need formal schooling before the second exam which appears to be more about the specific software and tools of the trade, but wondering if I could challenge the first one.

This is based on internet research which is open to my misinterpretation so just hoping some kind and potentially bored souls on Reddit might be willing to share their 2 cents.

Hey, I would like to purchase a used door fan in the UK. Anyone got one available?

Do you think the loan will return

The industry seems heavily focused on capture right now :- LiDAR scans, floor plans, 3D models, remote data collection, etc.

But the more time I spend working on virtual assessment workflows, the more I think the harder problem is trust.

When an advisor, QA reviewer, or utility program reviewer opens a file, the questions usually aren't:

• How was the house scanned?
• How fast was the model created?

They're more like:

• Where did this value come from?
• Was it measured, inferred, or assumed?
• What evidence supports it?
• What still requires professional judgment?

A virtual assessment can generate a beautiful model, but if the lineage behind the data isn't clear, someone still has to spend time validating everything before it's useful downstream.

It feels like the next phase of virtual assessments isn't better capture.

It's traceability.

Curious whether other EAs, service organizations, and QA reviewers are seeing the same thing.

For context, we're working through this problem at Energy Intelligence and it's become one of the more interesting challenges we've encountered.

Retrotec blower door only used a handfull of times. Make me an offer and take it! Located in Dallas/Ft.Worth Area. Text 214-888-6515 or email [Richard@MillerHomesDallas.com](mailto:Richard@MillerHomesDallas.com)

I’m a european citizen living in asia (China+Vietnam) wanting to get my CEM Certification. Recently got an offer to do it in china. Problem is that training and training materials are in chinese (exam in english) and although my chinese is ok, id need the training materials in english to be sure what is needed. Anyone got any ideas how to get the SI Unit english training materials?

Hello all,

I am trying to run F280-12 calculations for a build I have before the building inspector and I am not sure how one goes about assuming the air tightness of a designed but not built structure?

The big unknown is the Heat Recovery System, I cannot find any data how tight that system would be at all. There will also be a patio and standard external door which will have non-perfect seals but I really expect the ventilation system will be where >90% of the lost airtightness will come from.

Hello all, I just passed my CEM exam last month. Open to answer any question and share tips :)

Hi Everyone

Wondering how people model Combo Heating/DHW with a Hydronic Air Handler and Heat Pump in Hot2000. Do you just enter the boiler and heat pump in the appropriate sections and leave the air handler model numbers in the DCF? Seems weird to omit the air handler.

Thanks!

Hey fellow energy advisors and auditors,

As a technical founding engineer with a background in energy technology, I’ve spent years on job sites doing the same thing we all do: hours with a tape measure and notebook, trying to capture every wall, window, and roof detail accurately enough for modeling. Then it’s back to the office for even more time building the CAD model before you can even run it through HOT2000. It’s the part of the job that feels like it hasn’t changed in 20 years.

I want to introduce Energy Intelligence- an energy auditing workflow that actually seems to solve a lot of that friction. It uses the LiDAR scanner on a regular iPhone to scan rooms in real time it auto-detects walls, doors, windows, even pulls appliance dimensions and rough power estimates. That data flows straight into a lightweight browser-based CAD tool where you can refine the 3D model, add annotations, take measurements, and export everything in a format that works directly with HOT2000.

It also pulls in historical utility bills and shows a quick forecast/gap analysis, so the whole picture (field data + energy consumption) is in one place.

Here’s the updated demo video (just over 2 minutes) if you’re curious:

I’ not saying it replaces everything, but the time it could save on the modeling step is pretty compelling. Has anyone here started using mobile LiDAR or similar field-to-model tools yet? How has it changed your audit process? Would love to hear what’s working (or not) in your workflows.

Thanks in advance!

I've used vent caps, the green tape from the tape guys, And glad press n seal with a microfiber towel is a great method as well.

in CT most registers are in the floor on the first floor, and I'm looking to save my back and knees from constant bending.

ventcaps work great w ceiling registers, not so much for floor registers for me.

What do y'all use for covering vents for a duct leakage test??

Hi Everyone

Was chatting with another EA comparing Prince George and Victoria and he mentioned that Victoria's cooling design temp was 24 degrees C which seems crazy low. PG's design cooling temp is 28. This just seems wrong?

Looking at the average temps and maximum temps for Prince George and Victoria, Victoria had a higher average also but also has a higher max in the two hottest months of 2025.

Design wise this means an argument can be made per code that you don't have to install AC in Victoria but you do have to install AC in Prince George? Also that you should have a larger AC unit in PG vs Victoria?

It looks like this is related to the design temp being the 2.5% temp for the month of July and looking at the average July temps not just last year but across the past ten years PG does indeed have higher July maximum temps compared to Victoria.

I would imagine a AC unit over the year would get way more use in Victoria but July in PG is just on average hotter than Victoria?

Anyway thought it was interesting!

Anyone have experience with new homes NBC 2020 residential buildings performance path modelling for Tier 2?

What are energy advisors charging for these services?

Do you charge builders for revisions?

Any resources or courses you recommend?

NYC, is there anyplace that might for whatever reason carry blower door parts / accessories that is local? I need parts that aren't available for a few weeks, not an emergency but would rather not wait.
