I'm currently using OS 2.9.1 and model a residential building in which I wanted to apply a Low Temperature Radiant Floor. I seemd to have read all posts regarding this topic (this seem closest link text) and might have found the the reason for the error message: * Severe * ZoneHVAC:LowTemperatureRadiant:SurfaceGroup = LOW TEMP RADIANT CONST FLOWFLOORS does not have any surfaces listed.

Comparing a working model with mine (both have the same construction set) I can see in the Spaces Tab -> Surfaces, that in the working model the internal source floor is applied to a surface that is another one than the surface of the ground floor. In my model there exist only the surface of the ground floor (even tough I applied exterior, interior and ground floors in my construction set).

I was wondering how I can apply the internal source construction that it creates a new surface for the interior floor or whether I have to make changes in the geometry for which I use Floorspace JS.

Thank you for your help!

I have only found a "quick and dirty" solution in applying the MEASURE AedgOfficeHvacRadiantDOAS (this should happen in first place before starting with your HVAC as this measure replaces existing HVAC).

The Measure kind of created the missing surfaces for the internal source construction which is necessary for the LOW TEMP RADIANT CONST FLOWFLOORS. I could easily exchange the automatically applied varbiable radiant system to the constant one in Thermal Zones Tab and adjust the automatically created internal source constructions that they correspond to my former floor constructions. Now my model is working.
