Title 24 in Climate Zone 9
- Windows: U-factor 0.30 or lower and solar heat gain coefficient (SHGC) 0.23 or lower, with total window area up to 20% of floor area (west-facing up to 5%).
- Whole-house fan required (at least 1.5 cfm per square foot of floor area); units of 500 sq ft or less are exempt.

HVAC design for Granada Hills
The California Energy Commission's design-day data for Granada Hills gives the outdoor conditions a Manual J load calculation uses: a summer design temperature of 93°F and a winter design temperature of 28°F.
| Summer design (1%) | 93°F dry bulb / 68°F wet bulb |
|---|---|
| Winter design (median of extremes) | 28°F |
| Daily temperature range | 37°F |
| Elevation | 1,032 ft |
| Heating degree days | 664 |
Both seasons matter here. The heat pump is usually sized for the 93°F cooling condition and then checked to confirm it still covers the heating load at 28°F.
Electrical service from Los Angeles Department of Water and Power (LADWP)
If the load calculation shows you need a service upgrade, a second meter or a relocated service, Los Angeles Department of Water and Power (LADWP) handles that through its Electric Service Planning, separately from the building permit.
