“…Furthermore, thermal acceptability was rated at 68% during the cool season and only 33% during the warm season. These results may suggest that these houses are more suitable for the cool season; however the divergence from the neutral temperature was of a similar magnitude in both seasons (see tables 12,13). It may be concluded therefore that people in this region find it easier to cope or adapt to cooler conditions with the aid of warmer clothing during the day and the use of thick blankets at night, but find it more difficult to adapt to warmer conditions.…”

“…Previous studies have reported positive findings from the use of multi-layer construction strategies for houses in warm climates such as Turkey [12] and Mexico [13]. Findings indicate that when two construction systems with the same thermal resistance and thermal capacity are compared, the system with more layers results in an improved thermal performance, defined as a reduction in the decrement factor or increase in the time lag (see section 3.2.).…”

Key wordsPerformance evaluation, Thermal comfort, Thermal adaptation, Housing design, Industrialised building systems, Mexico Highlights¥ The thermal performance of a low-cost concrete house building system is analysed. ¥ Monitoring and a field survey are used to assess environmental performance. ¥ Thermal adaptation is easier for subjects in the cool season than the warm season. ¥ Poor performance is blamed on a ubiquitous design unsuited to the local climate. AbstractThis paper examines the performance of a case study of low-income housing situated in a warm-temperate climate (Morelia, Mexico). It represents the first comprehensive evaluation of thermal comfort in a widely used concrete formwork construction system in that country.The study was conducted in two seasons, determined by climatic analysis identifying the months that presented the most extreme conditions during the year. Indoor thermal conditions were monitored and are compared with the adaptive comfort temperature and comfort zone derived from existing standards.A thermal comfort field survey was also conducted, including the distribution of questionnaires in both seasons. The findings are compared with monitored data to assess the overall thermal performance of the housing typology.The results reveal poor thermal performance with houses falling significantly outside the thermal comfort boundaries in both periods due to a number of factors, including the properties of the building envelope, the impact of solar radiation, the number of occupants and their behavior. The results indicate that it is easier for subjects to adapt to cooler rather than warmer conditions. These findings expand existing knowledge of the performance of this concrete formwork system in Mexico as well as other industrialised building systems in similar climates. It demonstrates the urgency of designing viable solutions according to local climate, and questions the use of identical housing prototypes across different climatic regions.

“…A recent study conducted by Rincón et al [27] in this location used an adobe building of similar size to assess thermal comfort in earthen buildings. Other authors used similar test cells to investigate thermal performance of building in locations such as Mexico [28], France [29] and Switzerland [30]. Their work showed that test cells represent practical and efficient means to gather high quality data for empirical validation.…”

“…Alonso (2015) for her doctoral thesis used the same test cells from GESLAB to study the energy rehabilitation of facades: Methodological proposal for the evaluation of innovative solutions, based on the diagnosis of social housing built between 1940 and 1980 [14]. Additionally, Rojas et al (2015) used two non-air-conditioned outdoor test cells and simulations to study the thermal performance of two envelope systems in Mexico [15]. in Ireland, studied the behavior of a suspended particle device switchable glazing in an outdoor test cell with heat removal under varying weather conditions.…”

Thermal Performance of Facades Based on Experimental Monitoring of Outdoor Test Cells in Tropical Climate

The high cost of energy consumption in buildings highlights the importance of research focused on improving the energy efficiency of building’s envelope systems. It is important to characterize the real behavior of these systems to know the effectiveness in terms of energy reduction. Therefore, the aim of this paper is to characterize the thermal performance of facades based on experimental monitoring of outdoor test cells in tropical climate. To carry out this research, a case study was presented to compare two construction systems. One of them is a light façade (M1) and the other a reference façade (M2). A thermal simulation was performed for the opaque and glazed facades. In addition, several parameters were measured with different types of sensors, as well as environmental variables to evaluate the thermal and lighting behavior of multiple facades systems under real conditions. The findings show that light façade behavior was the opposite of what was expected, since by incorporating a window in the façade it has allowed solar radiation to increase the interior temperature in both modules. In the case of the light facade the penalization was higher than the reference facade, which has a lower thermal transmittance than M1. Doi: 10.28991/cej-2021-03091773 Full Text: PDF
