“…8 shows a detail of the thermal pattern over a typical 48 hour period from week five. Broadly speaking, all rooms followed similar oscillations, with little discernable difference due to orientation except for houses facing south (7,8,9), particularly in the common spaces, which tended to be a little warmer.

“…Air conditioning or cooling represents the third largest electricity end use in Mexico with an average share of 24%, after refrigerators and televisions that have an average share of 35% and 26% respectively [7]. A significant number of new housing developments have serious comfort problems, reflected in a high consumption of energy [8].…”

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.

“…Chitnis and Hunt (2012) estimated that CO 2 attributable to households would not fall by 29 % (or 40 %) by 2020 compared with that in 1990. Rosas-Flores et al (2011) focused on the estimation of energy consumption, energy savings, and reduction of emissions of CO 2 related to the use of urban and rural household appliances in Mexico between 1996 and 2021, which can be useful to policy makers as well as household appliance users.…”

Given the large expenditures by households on goods and services that contribute a large proportion of global CO 2 emissions, increasing attention has been paid to household CO 2 emissions (HCEs). However, compared with industrial CO 2 emissions, efforts devoted to mitigating HCEs are relatively small. A good understanding of the effects of some driving factors (i.e., urbanization rate, per capita GDP, per capita income/disposable income, Engel coefficient, new energy ratio, carbon intensity, and household size) is urgently needed prior to considering policies for reducing HCEs. Given this, in the study, the direct and indirect per capita HCEs were quantified in rural and urban areas of China over the period 2000-2012. Correlation analysis and gray correlation analysis were initially used to identify the prime drivers of per capita HCEs. Our results showed that per capita income/disposable income, per capita GDP, urbanization rate, and household size were the most significantly correlated with per capita HCEs in rural areas. Moreover, the conjoint effects of the potential driving factors on per capita HCEs were determined by performing principal component regression analysis for all cases. Based on the combined analysis strategies, alternative polices were also examined for controlling and mitigating HCEs growth in China.

“…In 2008, total electricity consumption for air conditioning in the residential sector was 9.3 TWh, corresponding to 19.6% of the electricity consumption for the entire sector [4]. Air conditioners had the third highest energy consumption among electrical appliances in urban Mexican households between 1996 and 2006, accounting on average for 24% of the energy usage [5].…”

The Effects of Roof and Wall Insulation on the Energy Costs of Low Income Housing in Mexico

Abstract:Environmental conditions, such as air temperature and solar radiation, have a complex relationship with the energy requirements for heating and cooling of residential buildings. In this work, a comparative analysis of the insulation methods most commonly applied to low income single-family houses in Mexico is presented, in order to find the most energy-efficient combinations of methods for the various climates in this country. A common kind of building, small houses built with hollow cinder block walls and concrete slab roofs, was analyzed considering three insulation scenarios: walls only, roof only and both. We used dynamic simulation to evaluate energy consumption under the climate conditions found in several Mexican cities. From the energy consumption data and the cost of electricity in Mexico, we calculated net annual energy costs, including both annual energy savings and the annualized cost of the initial investment in better insulation. Results of this analysis show that insulating both roof and walls is most effective in cities with cold winters; insulating just the roof is best for temperate climates; and insulating walls (combined with high-albedo roofs) is most effective for cities with year-long warm weather.
