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

Steps to reproduce
All the monitoring raw data were collected by using electronic Temperature sensors in modules simulating a portion of a Chilean social housing. The experiment was done under real weather conditions for the winter of 2017 and for the Summer of 2018 in Chillán City. A city of the Ñuble region in the south of Chile. These conditions were considered to test an experimental Low-cost and prefab Trombe wall. The experiment consists in measure the Temperatures difference between two “houses” or test cells. One, as a Case Base and the other with the designed low-cost and prefab component integrated in the North façade. The main experimental goal was looking for an affordable Trombe wall as a solar heater and demonstrate the energy-saving potential, and the capacity to provide some extra thermal comfort, in Winter and in Summer as well. Both houses were distanced the necessary to not shadowing each other even in the worst situation in Winter(Solstice of 21 of July). Because this mutual shadowing could affect the thermal behaviour of the shadowed module. Air Volume: Test cells, expressly reproducing the most commonly used area of a social housing unit (living room-kitchen) in combination with the most used type of window for the North facade. The interior space has the following interior dimensions: 3.45m(East and west facades) x 5.90m(North and south facades) x 2.25m(height). Both modules are identical and with an approximated interior volume of 45,78 m3.
