Hello from Las Vegas! This week is Autodesk University, and you may sign up for access to many great sessions and presentations from the comfort of your homw/office via Virtual AU (there is a registration fee). Check out http://au.autodesk.com/ for more info.
In my virtual session (which I'm about to also present 'in-person' in about a hour or so here at Mandalay Bay), I addressed that there is a commonly asked about limitation regarding non-coincident loads.. for example, if a building is strictly in a heating or a cooling mode, and you only need to account for the greater of the two in your electrical distribution. There is no specific functionality for this, however, I hinted that there may be a creative way to accomplish this. I had tried unsuccessfully to do this previously... when we first shipped Revit MEP 2011, there was a issue that one couldn't use calculated values in the 'Load Summary' section of the panel schedule (or something to that effect)... however, this had been addressed in one of our prior Service Packs, making this method possible.
See the method demonstrated in this video, and be sure to check out the AU Virtual Experience for more great information!
