HOT2000 Energy Modelling For Penticton Builds
HOT2000 energy modelling for Penticton Part 9 builders: permit-stage model inputs, Step Code reports, design coordination, and as-built updates.
Permit drawings need to be translated into an energy model before a builder can know whether assemblies, glazing, mechanical design, and airtightness assumptions line up with the selected Step Code path. Waiting until the permit package is already assembled can turn simple design decisions into late coordination problems.
Apollo reviews the drawing set, builds the HOT2000 model, coordinates assumptions with the builder or designer, and uses the model to support the pre-construction compliance report. The same file then carries forward through airtightness testing and the as-built report, so changes do not get lost between permit and occupancy.
Timing: Start before permit submission so the design team can adjust assemblies, glazing, airtightness targets, or mechanical choices while the drawings are still easy to revise. Update the file when construction changes affect the model, then use final test and commissioning inputs for the as-built closeout.
What to send: Send architectural drawings, window and door schedules, orientation, assemblies, insulation values, mechanical and ventilation notes, and any target Step Code or Zero Carbon Step Code requirement from the AHJ. If the project also needs mechanical sizing or permit ventilation documentation, include the inputs for CSA F280 or the TECA ventilation checklist at the same time.
Send the details that control the model.
- Floor plans, elevations, sections, and foundation details
- Wall, roof, floor, slab, and foundation insulation assemblies
- Window and exterior door schedules with sizes and performance values where available
- Mechanical notes for heating, cooling, domestic hot water, ventilation, and heat recovery
- Project address, municipality or AHJ, orientation, and target Step Code or Zero Carbon Step Code path
Use the model before choices are locked in.
- Check whether envelope assemblies and glazing assumptions support the target path
- Coordinate airtightness targets with the blower-door testing strategy
- Flag mechanical assumptions that should line up with F280 and TECA ventilation checklist inputs where those scopes apply
- Compare practical design adjustments before permit submission
- Keep model assumptions consistent with the drawings being submitted
Connect the model to permit and closeout reports.
- Use the model to support the pre-construction BC Energy Compliance Report
- Keep model-derived values aligned with the compliance checklist rather than overwriting them manually
- Track design or construction changes that affect the energy file
- Bring final airtightness and commissioning inputs back into the as-built package
- Provide the reporting package to the builder or applicant for the AHJ file
Avoid modelling delays before permit.
- Missing window schedules or unresolved glazing performance values
- Assemblies described differently across drawings, notes, and specifications
- Mechanical equipment or ventilation assumptions not identified before reporting is due
- AHJ Step Code or Zero Carbon Step Code target not confirmed
- Construction changes reported only after the as-built report is being prepared
What builders ask before booking.
Is HOT2000 needed before permit?
For Part 9 Step Code workflows, modelling is normally part of the pre-construction compliance package before permit submission.
What information affects the model?
Geometry, orientation, assemblies, insulation levels, glazing, mechanical systems, ventilation, domestic hot water, and airtightness assumptions all affect the model.
Can modelling change the design?
Yes. Modelling can identify whether envelope, glazing, mechanical efficiency, and airtightness assumptions should be adjusted before construction.
Who receives the model output?
Apollo provides the reporting package to the builder or applicant for the AHJ file.
Send the drawings and project basics.
Jesse Cummings reviews the file and returns a quote - base compliance package and applicable add-ons, priced by stage - within one business day after receiving the drawings and project basics.
