### Thermal Comfort Levels  
This section analyses the thermal comfort levels for each scenario and in each location. The prototype is considered a single thermal zone, so operative temperature is constant in all rooms. Besides, it should be noted that Discomfortable Applicable Hot Hours and Discomfortable Applicable Cold Hours have been categorized as \"comfortable\" because in those situations occupants may adapt to the thermal environment if they are in a free-running building; for that reason the value of these two categories is always null. Table 6 depicts the most relevant information. In the cities of Barcelona and Rome, Comfortable Hours increased from the current scenario to the SRES scenarios, mainly because the decrease of Discomfortable Non-Applicable Cold Hours was greater than the increase of Discomfortable Non-Applicable Hot Hours, with the rise of temperature being

the origin of both. However, this rise of temperature was greater in the RCP scenarios, thus leading to an increase of Discomfortable Non-Applicable Hot Hours, which were greater than the decrease of Discomfortable Non-Applicable Cold Hours, so the number of Comfortable Hours decreased. In the cities of Berlin, Bern, and Vienna, Comfortable Hours increased in all scenarios, except for the B1 in the cities of Bern and Vienna.
