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