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?

With the PHP certification, the overheating in Belgium is solved when the percentage of occupied hours when the operative temperature is above 25°C is less than 5% and for 28°C, less than 1%.
