REX Heat Load

REX Heat Load is an add-on that extends use of the Autodesk Revit MEP software. The extension enables calculation of design heat losses and design heat loads in accordance with EN 12831.

By default, design in Autodesk Revit MEP is based on the ASHRAE standards. Thus results of heat loads calculation differ significantly to those based on EN 12831.

Therefore, where accordance with European codes is required, values calculated with REX Heat Load can be used for design of heating systems in buildings – e.g. to select appropriate mechanical equipment as radiators, boilers, etc. and then implement them into the Autodesk Revit MEP model.

Moreover, calculation results received with REX Heat Load are saved in the Autodesk Revit MEP model and can be used later e.g. for schedules or space tags.


 
REX Heat Load automatically imports data from Autodesk Revit MEP. Therefore spaces and zones should be defined in the Autodesk software prior to the use of  the REX Heat Load add-on.
