HVAC design for Emeryville
The HVAC is sized from a room-by-room Manual J using the outdoor design conditions for the address, in Climate Zone 3's mild Bay Area climate. Load calculation on an older service before you assume a panel upgrade (or skip one).
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.
