Bioclimatic Prosthesis 01: Experimental dataset for a Low-cost Trombe wall to existing social housing refurbishment for two cities in the south of Chile.

This dataset is part of the research article entitled “Design and experimental study of a low-cost prefab Trombe Wall to improve indoor temperatures in social housing in the Biobío Region in Chile,” Ref. No.: SE-D-19-03183, submitted to Solar Energy journal. Specifically, the dataset presented is centered in experimental results for a 1-year monitoring campaign for an adaptable and low-cost prefabricated Trombe Wall (TW) with a vertical storage system. The tests also included periods for mobile insulation during winter nights and external shading during summer effects on Thermal performance.
Measuring was done using temperature sensors and compared to a similar test cell situated on the same site but without the solar passive component. The experiment was done in 2 different microclimates, consequently results from a coastal city (Coronel) and the interior valley (Chillan), were collected. Mediterranean temperate Csb(i) and Mediterranean (Csb), respectively, according to the Köppen climate classification.
In every city, two test cells were built, designed to represent the most used area of a social housing unit in combination with the most widely used type of window in north façades in the region. One of them was installed exactly like a social housing with the typical window to north facade, and in the other one, a low-cost Trombe wall was installed. Five temperature sensors were installed in the module with the BP_01(Bioclimatic Prosthesis 01); tree sensors were integrated on a vertical column(Sensors 1,2, and 3) to measure stratification degrees on the house. Another one on the opposite side of the space(Sensor 4) and the last one inside the Trombe wall(Sensor 5).
Electronic Temperature Sensors with Measurement error 1°C and a 0.1ºC resolution were used. The monitoring states (scenarios) and data collection were 6 for Coronel and 4 for Chillán. Including the first period with closed vent holes, secondly, open vent holes, and gradually adding more features as night shutters with insulation on Winter and an auxiliary fan, also a summer scenario with an external specially designed shadowing.
Observing all these measurements, the thermal efficiency of the TW was monitored and analyzed by the very first time in Chile, also the potential effectiveness of seasonal variations to improve winter and summer performances.
