Energy Evaluation missing walls and Openings

fuzzytnth3 — Thu, 11 May 2023 08:26:53 GMT

I'm trying to use the Energy Evaluation tool. What is puzzling is that it isn't including all the walls and it doesn't list any of the openings.

I have had a read of the manual and I've watched a youtube tut but all of them say they will appear in the appropriate UI window.

Any ideas what I am missing?

I have used Composite walls built for the Existing cavity wall with another Composite wall as the dry lining.

Darn just found the answer (obviously I read the wrong bit of the manual) wot it says is....

For best results with Energy Evaluation, follow these conventions of building energy modeling in ArchiCAD:
•
Use the Mesh tool to model the building site’s grade level, especially if it is uneven.
•
Do not use multiple separate parallel walls (or slabs or roofs) to model composite structures. If such constructions exist in the building model, make sure that only one of the parallel structures is visible in the energy model, and that the adjacent Internal Space Zones touch that structure.
•
Use fills consistently within your project: a particular fill should always indicate the same single building material or composite.

Hmmm yes and no.

I now have all the walls but still missing all the Openings.

The Zone Volumes look like this

If you select opening and choose opening elements(windows and doors) then it will highlight them from 3D window.

Thanks for the reply but sadly what you said didn't work for me. Any other ideas?

A tad weird but after going round checking reference lines were correctly meeting all the walls but no success. I then kept updating (a lot of times) the Zones and finally it is working.

I have now been able to make a comparison between an existing uninsulated property compared to an insulated property with better performing windows results in 25 percent reduction in Co2 emissions.
