I have (what is supposed to help) notes like "East BldMaterial-0 4.492825". I have spent hours checking my materials or looking for an wall, slab or roof with an area of 4.492825 square meters. I don't know if there is another way to solve this issue. Thanks in advance for your help.</P> <P>&nbsp;</P> <P><FONT face="courier new,courier" color="grey">Operating system used: <EM>Windows </EM></FONT></P> Wed, 18 Mar 2026 16:35:48 GMT Bidaya 2026-03-18T16:35:48Z https://community.graphisoft.com/t5/Sustainable-design/Missing-building-materials-during-energy-model-review/m-p/696285#M1334 <P>Hello everyone I am desperatly trying to launch the energy model review and I get a message mentionning errors with missing materials.
