[esp-r] Re: Heating and Cooling Loads

[Felipe Durán]

Leen,

I am working with the EPW climate file of Santiago de Chile in both  
soft wares. I ve modelled a zone of 10 x 10 x 3 mt. high with no  
ventilation and no internal gains. The results are:

ESP-r = 11.9 (heating), 1.86 (cooling)
IES = 14.6 (heating), 5.2 (cooling)

Now we got great differences in the cooling load. IES gave me 3 times  
more cooling loads than ESP-r

Any ideas how to go proceed?
