What does overheating mean in your country?
Various countries have their own terminology-regulation for overheating hours (like adaptive EN15251, CIBSE, TM52, 26C). Define the rule for overheating of your country for free running buildings (cooling).

@Theo, can you provide an example? Are you referring to unmet hours under a cooling load?
I think we are talking about, for example, in CIBSE, BB 101 defines overheating as more than 120hrs above 28C, and less than 5C difference between internal/external, or 0 occupied hours above 32C (2 of 3 of these criteria must be met). Theo, is this the kind of info you're talking about?
Yes, but from different countries around Europe and USA
