Análisis climático del Alto Valle de Río Negro para implementación de estrategias de diseño bioclimático

Abstract

Climate change, the energy crisis and energy poverty invite us to rethink the role of buildings in providing comfort in interior spaces. This study is applied to the region of the Alto Valle de Río Negro, Argentine, where 15 cities are located along an 88-kilometer valley, in a cold temperate climate with warm summers, where we expect to determine the most suitable bioclimatic design strategies for achieving hygrothermal comfort decoupled from the consumption of non-renewable energy. Given the lack of open climate records, we analyzed the feasibility of using remotely sensed data estimated by the MERRA-2 satellite. Furthermore, we evaluate the possibility of unifying the same strategies throughout the region. The results show that it is acceptable to use this database given the good fit between the estimated satellite data and the existing empirical records; as well as we observed high similarity between the climatic variables compared in a sample of 4 of the 15 cities in the region. By generating an EPW climate file for the area, and representing it in the Givoni diagram, we noticed that the most effective strategies are internal thermal gains, high thermal mass night flushed, and direct solar heat gain. To the best of our knowledge, this is the first study that carries out a detailed climatic description of the Upper Río Negro Valley, to determine bioclimatic design strategies in architecture.
