</strong>This is a great article from the ASHRAE magazine on
modelling. I hope I have given proper source credit to the people
involved so they don't mind my passing on of this information.<br>
My main point is modelling software is a tool and has wildly varying
accuracy depending on how it is being used and how skillfully it is
being used. Even in the hands of experts it produces coarse
results. There is a good graph on accuracy vs # of variables.<br>
Just something to keep in mind when you are trying to get rid of the
last 100 unmet hours.<br>
Perfection doesn't exist. Reality is, how close is close enough.<br>
