HVAC design for Capitola
The California Energy Commission's design-day data for Capitola gives the outdoor conditions a Manual J load calculation uses: a summer design temperature of 86°F and a winter design temperature of 27°F.
| Summer design (1%) | 86°F dry bulb / 65°F wet bulb |
|---|---|
| Winter design (median of extremes) | 27°F |
| Daily temperature range | 24°F |
| Elevation | 64 ft |
Both seasons matter here. The heat pump is usually sized for the 86°F cooling condition and then checked to confirm it still covers the heating load at 27°F.
Electrical service from Pacific Gas and Electric (PG&E)
If the load calculation shows you need a service upgrade, a second meter or a relocated service, Pacific Gas and Electric (PG&E) handles that through its Your Projects portal, separately from the building permit.
