Hi Alan, I have repaired the project - could you please hover over my name and send me a Private message with your email address so I can return it to you?

Morning Shane

I have a problem with loading the building database. Having traced out all of the building's rooms, including a reception room, I decided to delete the reception room to re-trace it.

The software threw up a database access error dialog box stating ' Room RECP, not found in database. To prevent possible data base corruption, Design Database will now shut down. '

When I try to reload the project, the Project Explorer says existing data 0 rooms. When I navigate to the database using Windows path/file it says there are 39 rooms ?

But the same database access error dialog box keeps appearing when I try to reload the project.

Is there a simple fix to reconnect the database? or is the data lost?

No problem at all, let us know how you get on. The roof sections with adapted U-value should be perfect in that instance.

Thanks Shane - its tricky for sure. I had thought about using vertical roof sections and giving it the same fabric u value as the exposed walls. I need to carry out heat loss and gains primarily. But I will take a look at the guidance and get back to you if I get stuck. Cheers.

Hi Alan,

This can be tricky to achieve however there are a few options - please see guidance here. An additional option may be to use vertical roof sections, if appropriate in this instance. The most valid method will be largely be determined by what calculations you wish to perform however.

Going forward, Hevacomp calculations are being transitioned over to OpenBuildings Energy Simulator. This offers much improved 3D modelling capabilities where this should be much simpler to achieve.
