MOLINA-FUERTES, Juan; HORN-MUTSCHLER, Manfred  y  GOMEZ-LEON, Mónica. Systematic evaluation of the thermal performance of an experimental module of high Andean housing to achieve thermal comfort with solar. Tecnia [online]. 2020, vol.30, n.1, pp.70-79. ISSN 0375-7765.  http://dx.doi.org/10.21754/tecnia.v30i1.841.

The objective of this work is to evaluate experimentally the thermal performance of an Experimental Housing Module (MEV) through systematic evaluation of twelve different configurations of operation, from nightly closing of window shutters until overnight stay, human activity, use of gas stoves and use of two active solar heating systems. This objective was based on the measurements of temperature and humidity, considering the first as the main parameter of thermal analysis to verify the thermal performance of the MEV by increasing the internal temperature with respect to the outside, according to the operability of the MEV, given that the variation between the average daily indoor and outdoor temperature, shows the effectiveness of passive heating or cooling strategies. Based on this, the temperature increases inside the MEV considering a conscientious operation of its implemented bioclimatic techniques and internal gains to reach its thermal comfort, are of the order of 9.5 ° C on average and, up to 16.6 ° C during critical hours of the morning with respect to the outside temperature of 7.1 ° C at 6 a.m.

The study is complemented by dynamic thermal simulations using the EnergyPlus software supported by the 3D SketchUp graphic environment, and OpenStudio interface to determine the indoor temperature and validate it with the actual measured indoor temperature. The results show a good agreement between the simulation and the experimental data, with an average square error of 15 and 16% in the MEV environments.
