The active role of the user in the search for thermal comfort of dwellings in a temperate arid climate

User behavior is one of the main factors of uncertainty in the thermal performance of a dwelling. This study contributes to identifying variables that would influence the user behavior and, in turn, how these affect the thermal performance of houses located in the city of Mendoza. For this, a thermal audit of a representative dwelling was made in summer and winter, while also recording occupancy and occupant actions. It was concluded that, in summer, correct management of the envelope through night cooling favors reaching indoor comfort in 89% of the recorded data. In winter, the correct use of direct solar gain favors reaching comfort in 60% of the recorded data. Finally, alternatives for building improvements are evaluated for the most unfavorable season.
