Why am I receiving these errors? I used the standard weather data provided.

3.xml:  Warning: No EPW design conditions found; calculating design conditions from EPW weather data.
1.xml:  Warning: No EPW design conditions found; calculating design conditions from EPW weather data.
2.xml:  Warning: No EPW design conditions found; calculating design conditions from EPW weather data.
4.xml:  Warning: BackupHeatingActiveDuringDefrost does not apply when system has separate backup heating.
4.xml:  Warning: No EPW design conditions found; calculating design conditions from EPW weather data.

Thanks

That's strange, you should not be seeing them for any TMY3 EPW weather file (which is what BEopt ships). Can you provide your BEopt project file?
