Hi Dominic,

Also, just in case you were not aware, please note that Energy Simulator can already do Overheating simulations, via the Frequency Simulation:

Overheating Simulation - OpenBuildings | Bentley Communities

As Krishnendu mentions the specific reports for TM52 etc are to be added to this, however Hevacomp remains available as an option for this in the meantime, as it can accomplish openable windows and TM52 results as shown here.

Models can easily be brought from Energy Simulator to Hevacomp via GBXML to aid with this:

Hi Krishnendu, good to know you guys are working on it. As you may know it's a 'hot topic' at moment given the record temps reached in the UK this week.

Looking at some of the reports produced to show compliance, it would be good to have a purpose made tool and workflow for this.

Don't fully get the differences between 52 and 59 but the window openings g value, shading etc ie envelope and context would be key feedback and input items for the model. OBD etc seem well placed as a physical and analytical modeler here.

Hey Dominic,

Great point! We are storming internally here to inculcate overheating assessment features in OBD, hence your query adds tremendous value to that. Hevacomp is capable of performing CIBE TM 52 calculations at the moment, hope that helps you to a certain degree?

Regards,

Krishnendu
