La incidencia del uso de la tierra de la Ciudad de Liberia como material constructivo en el desempeño higrotérmico de los espacios internos mediante técnicas de simulación.

Liberia city, head of the homonymous canton, located in the Guanacaste province, is characterized by its
earthen architecture. In this city there are more than 120 buildings with earthen architecture, 9 of them were
declared as Historical Architectural Heritage. At the same time, Liberia is in one of the most impacted regions
by the effects of climate change. Every year, extreme events cause variations in its temperature between -
0.9ᶱC and +0.9ᶱC, it is also the city with the lowest average of rainfall in the region and during dry external
events, annual precipitation could decrease by 26%.
Earthen walls have a high thermal inertia, which results in a slower thermal transmission inside the spaces,
so the houses remain cool during the day. In addition, earthen walls breathe, which helps regulate air humidity.
Based on these aspects, which are problems detected in the study area, and the notorious presence of
earthen architecture and its hygrothermal characteristics, this project is proposed, which aims to analyze the
incidence of soil use in Liberia City as a construction material and its hygrothermal performance in internal
spaces through simulation techniques. To this end, a research team is made up of professionals from the
following TEC schools: Architecture and Urban Planning, Agronomy and Materials Science and Engineering.
This project is planned in three phases, each one corresponds to a specific objective and its methodological
strategy involves professionals from the different disciplines that formed the teamwork. The first objective
proposes to analyze the physical, chemical, and thermal properties of Liberian soil as a construction material
used in the manufacture of adobe and bahareque. To this end, a series of analyzes of soil samples from the
area will be conducted at the CTLSC Agronomic Analysis Laboratory, as well as at the Materials Engineering
Research and Extension Center (CIEMTEC) attached to the Materials Science and Engineering School.
The second objective is to determine the climatic characterization of Liberia City, to obtain factors that allow
the identification of comfort aspects in internal spaces of buildings. For the development of this phase, in
addition to the consultation of data from the existing meteorological stations, a monitoring of the hygrothermal
conditions will be conducted inside the Liberia’s Cultural House located within the Historic Center, through
electronic devices for data recording. (datalogger).
The third objective proposes to determine the hygrothermal behavior through simulations conducted with a
climate analysis software in the internal spaces of the Liberia’s Cultural House. To this end, a three-dimensional model of the House will be developed, with a level of detail (LOD) one hundred, based on the
point cloud generated by three-dimensional scanning.
