3. Results and conclusions
The building analysed is the Building Pavilion, whose construction system is traditional, the spaces are distributed on two floors with central corridor illuminated overhead, the facades have east and west orientation. There is a central heating system that supplies all the useful spaces and cooling systems only in the office spaces. The period analysed objectively covers from November 2016 to February 2019 and records were collected every hour. Table 1 shows that the objective thermo-hygrometer comfort conditions are only reached in a range between 7.24% and 21.17% of the hours, despite the existence of air conditioning systems, and these percentages are duplicated considering only temperature conditions.

The subjective survey was launched in February 2019 and it is still in process. Therefore, the results are still partial. Initial results suggest that the adaptive comfort range is higher than that established by RITE, with users in comfort at slightly lower and higher temperatures than those established in the objective analysis. It must be taken into account that users can interact with windows and blinds, that is, with ventilation and shading; In addition, clothing is adaptable to the operating conditions of the interior spaces for each user.
In conclusion, thermal sensation of comfort could be improved through the user's interaction with the building envelope, along with the selective use of the spaces according to the time of the year, the hours of the day, the orientation, and activity, among other factors.
