Previous experience in designing and monitoring bioclimatic buildings in central Argentina suggeststhat their thermal behavior is a matter of concern and that further research is needed. Thus, the objec-tives of this work are: to describe the design and the post-occupancy evaluation of a new non-domesticsolar building in a continental semiarid region of central Argentina (37◦38latitude S, 63◦34longitude,175 m above sea level), to analyze the building?s hygrothermal and energy performance, and to estimatethe PMV and PPD. The design guidelines were: to minimize the consumption of conventional energy inthermal-lighting conditioning, to use traditional technology, to maximize the thermal comfort, and toreach an extra-cost lower than 10%. The post-occupancy monitoring of the building was performed alongone complete year (August 9th 2011?August 18th 2012). Data-loggers were installed in each functionalarea to sense the indoor temperature and relative humidity at time steps of 10 min. A meteorologicalstation was installed near the building. The experimental results showed that during winter the averagetemperature in the areas of permanent use was 20.3◦C (average outdoor temperature: 10.1◦C) and theheating energy consumption was around 73.5 kW h/m2. During summer the average indoor temperaturein the building was 26.9◦C, 1.7◦C below the outdoor temperature average (28.6◦C); cooling systems wereturned on when the indoor temperature reached 28◦C, at approximately 11:30 AM, when the outdoor airtemperature exceeded 30◦C. Mechanical cooling consumed around 59% of the daily electricity consump-tion. The PDD results obtained for winter and summer representative days meet the requirements of ISONorm 7730. Heating and cooling energy saving was around 63% and 76.5% respectively. The monitoringshowed that the thermal behavior and energy performance met the expectations of both designers andusers, and it is considered satisfactory and promising for low-energy consumption buildings.
