[Equest-users] eQuest - Electricity consumption for cooling in winter

[František Bartoš]

You´re right that we didnt define server room as a distinct zone. This 
model is for LEED precertification and the documentation is in very 
early stage so we don´t know positions and sizes of these rooms. Thats 
why I thought it would be enough to add expectation of percentage of 
floor area to zone description.

We just need to be sure to get 28% improvement of proposed building 
against baseline building.

I´m sending files from equest so you can look at it. Floor plan is in 
file "pokus002.dxf".

I´m using eQuest 3.65. Thanks for advice.

Best Regards

F.Bartos
