Most builders think of energy modelling as a compliance checkbox. Something you need to get the permit, then file away and forget. But the builders who use energy models strategically are consistently saving $15,000 to $30,000 per project. Here is how.
What an Energy Model Actually Is
An energy model is a computer simulation of your building. Using software called HOT2000 (the standard in Canada), we input every detail of the building: wall assemblies, insulation values, window specs, orientation, mechanical systems, and more.
Think of it like a flight simulator for your building. We can test different scenarios before you commit to any of them.
Real Example: The Triple-Pane Window Trap
One of our clients was building a 2,800 sq ft custom home targeting Step 3. Their architect had specified triple-pane windows throughout, a common assumption for Step Code projects.
Total window cost with triple-pane: $68,000.
We ran the energy model and discovered that by increasing the attic insulation from R-50 to R-60 ($1,200 extra) and improving the air sealing details at rim joists ($800 in spray foam), the home could meet Step 3 with high-quality double-pane windows instead.
Total window cost with double-pane: $42,000.
Additional insulation and air sealing cost: $2,000.
Net savings: $24,000.
What It Costs vs. What It Saves
| Item | Cost |
|---|---|
| Energy model (typical single-family home) | $1,500 to $3,000 |
| Typical savings from optimization | $10,000 to $30,000 |
| ROI | 5:1 to 20:1 |
| Time to complete | 5 to 7 business days |
