Maybe this is a rather elementary question, but I've got two completely different HVAC systems that work in two different areas of an office building (though they're on the same boiler loop), and I can't seem to figure out how to get an annual heating/cooling load from each separately. I have been using the Heating and Cooling report feature, but even when highlighting only one area of the building, I am still getting an overall load for the whole building.
How do I work out the overall loads separately per HVAC system?
Thanks very much!

You can pull out the various room heating and cooling loads separately by simply selecting the required rooms and checking the "combine rooms" box. If you have no rooms selected then the variables will default to whole building values.

Another way would be to set up two separate systems and apply them to the appropriate rooms before you run the model. In Vista you should then be able to look at the global variables per system type.

just to add as it's not immediately obvious, to view results & variables for a specific system in Vista just click on the Room Groups dropdown on the rooms browser and choose the system, this works for apache system or ApacheHVAC systems. Switch the dropdown to the system you want and then select that system from the browser, you should see at that point the rooms assigned to the system are highlighted or the HVAC network is shown
