“…To evaluate the thermo-energetic performance of the strategy, the EnergyPlus [12] software was used through the GroundDomain: Basement (GDomain) input, which calculates the temperature of the interface between the soil, the external walls, and the slab of the bermed earth-sheltered spaces, obtained three-dimensionally by the simulations [13]. Thus, the simulation was carried out considering temperature models named "Finite Difference", which use a model with finite differences to obtain the soil heat transfer.…”

This study addresses passive adaptation strategies to reduce the effects of global warming on housing, focusing on low-income houses, for which passive adaptation strategies should be prioritized, aiming for environmental sustainability. The passive strategy chosen is thermal mass for cooling, through the adoption of earth-sheltered walls in contact with the ground. Thus, the goal of this study is to evaluate the thermal load and thermal impact of implementing a thermal mass strategy for cooling, using bermed earth-sheltered walls in bedrooms, for a building located in a tropical climate region. For that, a base scenario (1961–1990) is considered alongside two future scenarios: 2020 (2011 to 2040) and 2050 (2041 to 2070), both considering the effects of climate change, according to the Fourth Report (AR4) of the Intergovernmental Panel on Climate Change (IPCC). The methodologies adopted are (i) the computational simulation of the annual thermal load demand and (ii) the quantification of the Cooling Degree-Hours (CDH) with the subsequent comparative analysis. The results show that in both the 2020 and 2050 scenarios there will be an increase in the thermal loads for cooling and the CDH, regardless of using a bermed earth-sheltered wall. Nonetheless, it is shown that this passive strategy works as a global warming adaptation measure, promoting building sustainability in tropical climate regions.

“…One way to evaluate the thermal performance of a building is through computer simulations, and these properly validated tools allow the prediction of thermal comfort indices in a representative manner (Silva et al, 2016). According to Resende et al (2019), EnergyPlus stands out among thermal performance simulation programs, and it is one of the tools recommended by the NBR 15575 standard (ABNT, 2013).…”

For studies of thermal performance, computational modeling has been presented as an important decision-making tool to solve complex and everyday problems in poultry production and research. Thus, the present study aimed to validate computational models developed using the EnergyPlus software package and, based on these, evaluate the thermal performance of a poultry house with different types of tiles (thermoacoustic, ceramic, fiber-cement, and metal). The research consisted of two stages: an experimental phase and another phase in which the climatic conditions in four aviary models are numerically simulated, considering different types of tiles. The experimental phase was conducted in two climate seasons, winter (2019) and summer (2020), where air temperature and relative air humidity data were measured and recorded using six HOBO model H12 data loggers distributed inside an aviary located in the semiarid region of Pernambuco state, Brazil. For the computer simulation, a virtual model of the house was developed using the OpenStudio graphical user interface in Sketchup, and the thermal performance was calculated using the EnergyPlus software package. The models were validated, showing a strong correlation between the experimental and simulated data, with Pearson’s correlation coefficient (r) values greater than 0.95. The simulations demonstrated the influence of the roof tiles on the thermal performance of the evaluated building. For the climatic conditions of the semiarid region of the Pernambuco state, thermoacoustic roof tiles presented the best thermal performance, followed by ceramic, fiber-cement, and metal roof tiles.

Bermed Earth-Sheltered Wall for Low-Income House: Thermal and Energy Measure to Face Climate Change in Tropical Region

Climate change impact is one of the most important global concerns at present. In the building environment, climate-responsive design may help to enhance the adaptation capacity through a better building energy performance. In this sense, this study addresses an adaptation strategy to reduce the effects of global warming on low-income houses, for which bioclimatic passive strategies should be prioritized, aiming to improve environmental sustainability. The technique chosen to be analyzed is thermal mass for cooling. Thus, the goal is to evaluate the energy consumption and thermal performance impact of implementing bermed earth-sheltered walls on bedrooms in low-income housing (LIH), considered deployed in tropical climate regions. For that, a base scenario (1961–1990) is considered, alongside two future scenarios: 2020 (2011 to 2040) and 2050 (2041 to 2070), both considering the effects of climate change, according to the Fourth Report (AR4) of the Intergovernmental Panel on Climate Change (IPCC). The methodologies adopted are (i) computational simulation to estimate the annual energy consumption demand and (ii) quantification of the cooling degree-hours (CDH), with the subsequent comparative analysis based on Brazilian regulation for energy efficiency in buildings (RTQ-R). The predictions show that there will be an increase in the energy consumption for cooling and in the CDH in both 2020 and 2050 scenarios, regardless of using a bermed earth-sheltered wall. Nonetheless, this adaptive measure enables the building to be resilient in terms of cooling energy demand in the 2020s, since it is 12.3% lower than in the building without the strategy use, compared with the base scenario. In the 2050s, resilience was almost reached with energy consumption only 10.7% higher, for the same conditions described previously. Therefore, bermed earth-sheltered walls work as a climate-responsive design strategy to face the potential global warming effects, promoting building sustainability in tropical climate regions.
