Numbers & Facts: Passive House vs Code-Built Homes - YouTube
This video from EkoBuilt Passive Homes compares code-built homes to passive houses, highlighting significant differences in insulation, efficiency, and cost.
Key Comparison Points:
- Building Envelope & Insulation (R-Values): Passive houses utilize superior insulation to maintain a stable environment. While code-built homes often rely on standard fiberglass or rock wool, passive houses use materials like cellulose (which is 100% recycled/renewable and can be made fire/mold-proof with borate) to reach significantly higher R-values (0:56 - 5:51).
- Walls: R-24 (code) vs. R-75 (passive)
- Floors: R-10 (code) vs. R-40 (passive)
- Windows/Doors: R-3 (code) vs. R-12 (passive)
- Roofs: R-36 (code) vs. R-110 (passive)
- Window Performance: Passive house windows are triple-glazed, thermal bridge protected, and engineered to maximize solar heat gain in winter (6:02 - 8:05).
- Cost & Savings:
- Incremental Build Cost: Building a passive house is roughly 5-10% more expensive initially due to the high-performance envelope (2:19).
- Utility Savings: While the average Canadian utility bill is ~
50/month** (with net metering) or $100/month without it (8:20 - 10:28).
