HERRERA-SOSA, Luis Carlos; VILLENA-MONTALVO, Edgar Elias  and  RODRIGUEZ-NEIRA, Karin Rosario. Evaluation of the ashlar (ignimbrite) thermal performance of Arequipa, Peru. Rev. Arquit. (Bogotá) [online]. 2020, vol.22, n.1, pp.152-163. ISSN 1657-0308.  https://doi.org/10.14718/revarq.2020.2261.

The ashlar, construction material for walls and roofs commonly used in Arequipa (Peru) has lost its validity of use, due, among other things, to ignorance about its thermal performance. Thus, the aim of this research was to evalúate such performance compared to adobe, clay brick and concrete block. The methodology consisted of an experimental monitoring of six modules in summer and eight in winter, in field models with cause-effect analysis through simulation. By comparing the temperature of the outdoor and indoor air with that of comfort, the material that has the best thermal performance in the two climatic seasons of Arequipa was identified. With the use of the DesignBuilder V4.7 software, the modules were thermally simulated, the results were correlated for validation and energy consumption Índices were obtained. Field results showed that the ashlar in its soga and canto placement shows the best thermal performance, while the concrete block is the most inefficient.
