BRITO- PENA, Rodrigo; VILLA- ENDERICA, Daniel  and  ZALAMEA- LEON, Esteban. COMPARATIVE ANALYSIS OF THERMAL COMFORT OF A SINGLE- FAMILY HOUSE IN LSF AND BRICK MASONRY. Ingenius [online]. 2022, n.28, pp.100-124. ISSN 1390-860X.  https://doi.org/10.17163/ings.n28.2022.10.

Residential construction in Ecuador has recentlygrown by 35.6%. The typical construction systemfor housing envelopes is concrete block or brick, constructionin LSF, Light Steel Framing or galvanizedsteel frames (LSF,) is emerging. To solve the housingdemand, the thermal interior comfort of a two-storysingle-family home in the city of Cuenca is evaluatedwith both construction systems to know thecomfort standards offered by homes in accordancewith the Ecuadorian Construction Standard. (NEC).The research was carried out with Design Builderand Therm where the parameters that influence theenergy performance of homes are analyzed. Underlocal conditions, the predominant system reaches annualhourly thermal comfort values of 51%, but theLSF system reaches 62%. However, with improvementstrategies in the overall envelope, the LSF reaches86%. The variables in order from greater to lesser thermalinfluence resulted: Air infiltrations, constructionsystem of the envelope and implantation of the house.In Cuenca it is feasible to use the LSF with minimuminsulation to reach acceptable levels of comfort,being an adequate alternative to promote to buildsingle-family homes.
