Abstract

This work aims to study the thermal performance of small apartments in multi- family residential buildings (up to 50 m²), with fully or partially glazed facades, recently built and launched in São Paulo. Given the increase in global temperature, added to the local characteristics of urban heating, it is essential to problematize and study the thermal performance of these small environments in future climate scenarios. The objective is to evaluate the thermal comfort of users and the energy efficiency of these buildings, given the demand for artificial conditioning, also considering the longer stay of residents and the new uses arising from confinement during the pandemic and, eventually, after - pandemic, due to new habits. Thermal analyzes were carried out using computer simulations based on current climate data and future projections. The analyses, developed with the support of thermodynamic simulation, made it possible to evaluate thermal comfort and energy efficiency indices, in a qualitative and quantitative way, in the face of climate change and new demands resulting from confinement, due to the pandemic. With this, it is possible to qualify and quantify the impact that decisions about the design, materials and construction components on the facades can have on the space built in this typology. The results presented that two (2) of the four (4) scenarios of proposed passive strategies are capable of achieving up to 85% and 80% of hours in thermal comfort by the year 2076, 10% more than the original project, and 20% more than in the glazed scenario. It was also found that in home office occupation the hours in discomfort are greater than in typical occupation and generate an average kWh/ YEAR consumption of 34% more than in typical occupation, including all scenarios, and all years of use simulation.
