I'm sorry to come back again to the problem of radiators but, it seems, even in the 2013 version is not so easy to design the simplest kind of heating system:

A boiler with some radiators. It is not simple in other word verify that the heating power introduced with the radiators is adequate as required by thermal analysis.

The issue was highlighted long time ago and don’t seem solution have been given up to now!.

Using the words of Moby21:

"In a typical scenario, the Max heat load to a space as calculated by the software, might be say 10kW. To maintain the space at the design temperature one might have to add 5 radiators each emitting 2kW"

The solution proposed seems a walk around.

No news for this problem ?

Thanks

Embedded schedules provide the information you are after... if you take a look my the prior posted example, it shows a space-by-space summary of the design heating load for each space, as well as a list of each mechanical equipment component and its associated heating output, with a sum.  So, for each space, you can see if the components in the space meet the load or not.

Perhaps you find this to be a 'workaround' because there is no built in tally for heat-output of elements placed within a space, as there is with the ability to tally airflows on a space.  I can see your point, as we never designed the software to facilitate the specific workflow you seem to be after... which is, to see the value populated 'automatically' on the Spaces.  There are at least a couple of reasons for this.  One, Mechanical Equipment is a rather generic category.  There is no internal mechanism for an element to indicate that it is a radiator, and what values it has for its heat input, output, efficiencies, etc...  Without an element knowing these details, there can be no built-in way to track the info you are after.

Two, there is a built-in mechanism to populate (shared parameters) and retrieve (schedules) the requested information that is in line with other similiar queries one may want to extract from the model, such as 'What is the total floor area required by Specialty Equipment in each Room' or 'What is the total cost of all furniture in each Space'?   By populating the model with the necessary params to track the type of equipment (radiator) and its output, you can extract the results you are looking for.

While there isn't built-in functinoality to address your specific model inquiry, Revit does provide generalizable tools to address the query and others like it.
