The thermal performance of economical housing located in hot climates remains a pending subject, especially in emerging economies. A cellular concrete mixture was designed, considering its thermophysical properties, to apply the new material into building envelopes. The proposed materials have low density and thermal conductivity to be used as a nonstructural lightweight construction element. From the design stage, a series of wall systems based on cellular concrete was proposed. Whereas in the second phase, the materials were analyzed to obtain the potential energy savings using dynamic simulations. It is foreseen that the energy consumption in buildings located in these climates will continue to increase critically due to the temperature increase associated with climate change. The temperatures predicted mean vote (PMV), electric energy consumption, and CO2 emissions were calculated for three IPCC scenarios. These results will help to identify the impact of climate change on the energy use of the houses built under these weather conditions. The results show that if the conventional concrete blocks continue to be used, the air conditioning energy requirements will increase to 49% for 2030 and 61% by 2050. The proposed cellular concrete could reduce energy consumption between 15% and 28%, and these saving rates would remain in the future. The results indicate that it is necessary to drive the adoption of lightweight materials, so the impact of energy use on climate change can be reduced.

The performance of a three-story laboratory building was analyzed to reduce its annual energy consumption. The analysis was performed through a whole-building simulation approach and dynamic simulations to calculate the potential reduction of heating and cooling energy requirements by evaluating various construction systems. The main objective was to accomplish a decrease in energy consumption without the implementation of sophisticated constructive systems, which are commonly unavailable or unfeasible to apply in developing countries. Therefore, a two-stage analysis was carried out. At the first stage, a set of commonly available construction materials were implemented. From this analysis, it was shown that the use of an insulated concrete wall, double tinted glass, and an insulated terracotta roof corresponds to the optimal combination of materials, resulting in a decrease of 36% on the total annual energy requirements. Finally, from the second stage analysis, where double-wall systems and a green façade were implemented, an additional energy saving of up to 16% was achieved.

The energy market in Mexico is facing changes due to the incorporation of clean energy certificates (CEL) on the Electric Industry Law (LIE, Ley de la Industria Electrica). One of the aims is to increase the percentage of clean energy use in the national energy matrix. Consequently, the integration of energy efficiency strategies prior to the incorporation of renewables has become essential at different levels. Industrial buildings have significant heat gains and losses through the envelope, mainly due to their vast surface and simple construction systems. This work analyses the typical envelopes of industrial buildings in Mexico and the effect of industrial rooftop photovoltaic (PV) systems over the annual energy consumption. It was found that for temperate climates, the best option would be to insulate the roof. For cities with warm climates, the best approach is to implement a cool roof on a non-insulated layer or to simply insulate the roof. Additionally, the industrial buildings with metallic roofs situated in warmer climates would benefit the most from the implementation of rooftop PV systems. After all, the results point out that the decrease in the required CELs would not influence the savings.

Four different shapes of a 182 m2 research greenhouse were analyzed using dynamic simulations. The thermal performance was evaluated using different cover materials at an equal floor area. In developing countries, the selection of the greenhouse shape, structure, and cover material generally is made based on the availability of the materials and considering the initial investment costs. The greenhouse is located on a cold semi-arid (BSk) climate according to the Köppen climate classification. This study aimed to determine the best choice of the greenhouse shape and cover material according to a technical-economic analysis. The analysis was conducted from a technical-economic perspective for this specific climate region. The results show the heating and cooling energy consumption for different cover materials and greenhouse shapes. The economic analysis was made to assess the investment and operative costs through the life span of the greenhouse.

Some of the greatest potentials for improving building energy efficiency are found in the residential sector. Social housing, in particular, has drawn heavy research interest because it affects the welfare of large populations, is the source of significant energy consumption, and has outsize importance in the construction and regulatory sectors. Energy regulation in Mexico focuses on reducing the energy needed to cool buildings down, neglecting the importance of heating buildings built in the colder regions of the country. To address this gap, the present work focuses on the thermal behavior of social housing in the regions of Mexico with cold semi-arid climate. We found that thermal discomfort inside houses is primarily driven by low temperatures. We calculated annual heat flows in houses, visualizing heat gains and losses through each part of the building envelopes, and found that the highest heat flows occur through the floor. We also found that windows have the greatest heat transfer per unit area of all construction elements. We estimated the energy that each building would require if heating and air conditioning were used throughout the year to bring indoor temperatures within the range of thermal comfort. Finally, we used evaluation schemas from several countries to evaluate the energy demand per unit area (kWh/m2) of several local houses in a typical year. The houses analyzed here presented low scores under these schemas.

The analysis of solar thermal systems through numerical simulation is of great importance, since it allows predicting the performance of many configurations in any location and under different climatic conditions. Most of the simulation tools are commercial and require different degrees of training; therefore, it is important to develop simple and reliable methodologies to obtain similar results. This study presents a parametric methodology to size stationary solar collector fields, with operating temperatures up to 150 °C. The costs of the collector loop piping and the pumping power of different series–parallel arrays is considered. The proposed tool was validated with experimental data and through simulations using commercial software. The tool allows establishing series–parallel arrays and calculates the volume of the storage tank according to the thermal load. The calculation is based on the system energy balance, where the mass flow and the heat losses in the interconnections of the collectors are taken into account. The number of collectors and the optimal series–parallel array were determined. The results show deviations lower than 7% in the relative error of the temperature profiles and in the solar fraction, with respect to the results obtained by dynamic simulations.

The building sector is considered a key area for sustainable development, due to the potential to reduce greenhouse gas emissions in the numerous economic activities that this sector involves. A low-cost lightweight cementitious composite consisting in perlite mortar was fabricated and evaluated. The thermal conductivity and heat capacity of the proposed composite were tested in the laboratory. The lightweight composite was integrated into a prototypical house and its thermal performance was tested for two different arid climates during a typical meteorological year. A techno-economic analysis of this integration was carried out, which showed the lightweight system integration could reduce the energy demand up to 10.3% due to the decreased use of heating and cooling systems. The CO2 emissions associated with electricity and gas use on cooling and heating systems could be reduced up to 10.9%.

In Mexico, residents of low income housing mainly achieve thermal comfort through mechanical ventilation and electrical air conditioning systems. Though government and private efforts have risen to meet an increasing demand for social housing, the average construction quality and thermal comfort of new housing stock has decreased over the years. Various programs and regulations have been implemented to address these concerns, including the 2011 residential building standard NOM-020-ENER-2011. This standard attempts to limit heat gains in residential buildings, in order to reduce the energy consumption required from cooling systems, and was intended to be applied throughout Mexico. NOM-020-ENER-2011, however, divides the country into just four climatic zones and only considers the energy use of cooling systems, disregarding heating costs. The recommendations of this policy are thus inadequate for the many regions in Mexico that have mild to moderate winters. This study discusses the assumptions and calculations that underlie NOM-020-ENER-2011, identifying several problems and recommending specific changes to the standard that would lead to greater comfort and lower energy use throughout Mexico.

A thermal analysis of a two-storey building was made using a dynamic simulation software (TRNSYS). Thermal performance of a 2000 m2 building was examined by means of several dynamic simulations. The building is located in a region within the BS climate (steppe) according to the Köppen climate classification, where both air cooling and heating are needed to provide comfortable thermal conditions through the entire year. This weather often represents an energy saving challenge, where heat gains and heat losses need to be efficiently managed. A selection of common construction and glazing materials was implemented, and a simple but effective ventilating strategy was tested. Six thermal zones were defined in the building and a comfort temperature range was established as an operating parameter. The results show hourly mean temperatures and energy consumption due to air conditioning throughout a year.

The experimental and numerical results of the heat transfer and airflow by turbulent mixed convection in a ventilated cavity are presented. The experimental setup was built to use air as the heat transfer fluid. One vertical wall receives a uniform and constant heat flux, whereas the opposite wall is maintained at constant temperature. The remaining walls are thermally insulated. The experimental temperature profiles were obtained for different heat fluxes and air inlet velocities. Five different turbulence models were used to obtain the numerical results. The comparison between experimental and numerical temperatures indicates that the standard k–ε turbulence model presents a better agreement, with maximum percentage differences between 2.0% and 3.0%. The heat transfer coefficient had values between 2.2 and 3.4 W/m2 K, and it increases with the Rayleigh number and the Reynolds number. The experimental and numerical convective heat transfer coefficient predictions are closer for the higher Reynolds number (inlet air velocity of 0.5 m/s). The effects of varying the Rayleigh and Reynolds number on flow patterns and temperature fields were analyzed numerically.

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.

A thermal analysis of ventilated office building was performed by the use of a dynamic simulation software. This work focuses on the analysis of a ventilation strategy, contribution to the thermal performance of a 2000 m2 building. The studied building is located in a region within the BS1kw climate according to the Köppen climate classification. In this climate, commonly referred as steppe, both air cooling and heating is needed in order to provide a satisfactory thermal comfort condition throughout the year. Within this weather it is possible to incorporate several energy saving strategies so the heat gains and losses can be calculated. The analysis starts with the incorporation of basic bioclimatic notions and the selection of commonly used construction and glazing materials. Several energy saving strategies were established; this strategies, such as the study of different materials and natural ventilation during the warm season. The results show hourly mean temperatures and energetic demands due air conditioning during the course of a year

Experimental and numerical results of heat transfer by mixed convection in a ventilated cavity are presented. The results were obtained for a 1.0 m × 1.0 m × 1.0 m cavity. The inlet and outlet dimensions were of 0.08 m × 0.08 m, and the air velocity at the inlet was set to 0.1 and 0.5 m/s. The left wall receives a uniform and constant heat flux whereas the right wall was maintained at a constant temperature. Experimental and numerical results of temperature profiles and heat transfer coefficients are presented and compared. The results showed that the variation of the Rayleigh number increases about 1% the percentage differences between experimental and numerical values, and the maximum percentage differences on heat transfer coefficients are 2.0% for Ra = 2.7 × 108 and 3.0% for Ra = 4.5 × 108.

This study is focused to airflow and heat transfer analyses in an air-cooled room. Three-dimensional numerical results of a rectangular room considering three different inlet configurations are presented. The study was carried out considering turbulent flow and the radiative exchange between the walls. A vertical wall receives a constant heat flux, and the opposite wall is maintained at a uniform and constant temperature; the remaining walls are adiabatic. The air inlet velocity was 0.5 m/s and the emissivity of the walls was considered as 0.8. The mathematical model was solved numerically with Computational Fluid Dynamics software. The temperature fields, flow patterns, heat transfer coefficients, and temperature distribution effectiveness are presented and discussed. It was found that the heat transfer due to the radiative effect is around 50% for the three cases studied; besides, the heat transfer coefficients and temperature distribution effectiveness are highly dependent on the inlet position.
