Hi all,

I was wondering if anyone knew how to utilize room symbols in heat load calcs.  One fine day, my architect drew in rooms in his architectural model.  I remember from basic training that these rooms were used in load calcs, however at that time, I recall putting in room symbols in our mechanical model.

The way it is now with the architect doing that (which I now believe to be the correct way), I don't know or have any experience in using them, since they are part of the linked file.  Hope someone can help!  So far you guys have been a great help!  Any leads would be fantastic.

You're going to want to read the help file on using spaces and zones.

In previous versions you copied / monitored the rooms from the RAC file but this changed in 2009 and now you add spaces, then zone and use those for you load calcs.


snipet from help:

"...Zone and spaces are independent components but are used together to achieve a common result. Spaces contain information about the areas that they have been placed in. This space information is used to calculate the volume of the area and to help determine a heating and cooling loads analysis. Zones consist of a one or more spaces that are controlled by equipment that maintain a common environment (temperature, humidity, and so on). Each zone contains zone information, such as heating and cooling temperatures and outdoor air information. Revit MEP uses both zone and space information during a heating and cooling loads analysis to determine the energy demands of the building."
