[Greenbuilding] [BULK] Furnace Efficiency Question

[Steve Houlihan]

HVAC-Calc assumes 71 and 38 as design temps for Santa Cruz and does account 
for bodies in the house and size and orientation of all windows.  I don't 
have, and don't need, AC even though it gets over 100 a few days each year. 
Typical Summer day is in the low 80's. It is a little colder up here in the 
Santa Cruz Mountains (only 800 feet elevation) than it is down in Santa Cruz 
itself so the Winter design temp may be a little high.

As I mentioned in another post yesterday, Sacramento is in the Central 
Valley and is in a whole different climate than the coast or Coastal Range 
were I am.
