[EnergyPlus_Support] Re: Heating/Cooling load

["Jean marais" <jeannieboef@xxxxxxxxx>]

Simulate the building without heating and cooling and see if it behaves as expected.

How, if at all, do you model infiltration? What kind of U-Values do you have for your constructions? Are they realistic? Are you outputting an AllSummary report to check things?

Check that your outdoor environment temperatures are what you expect.
