The Earth-Air Heat Exchanger (EAHE) is a device where the external ambient air is cooled or heated when circulating inside ducts buried in the soil, which can bring benefits in terms of reducing energy consumption and providing thermal comfort conditions. This system has been employed in several countries in different climatic contexts, however, little explored in Brazil. The use of this technology in conjunction with bioclimatic strategies benefits buildings, increasing their efficiency. This study aims to evaluate the thermal performance of an EAHE alongside optimization parameters of the building envelope in two Brazilian bioclimatic zones and propose strategies that enhance energy efficiency in buildings. The study consists of the validation and verification of a computational model and the thermal evaluation of a Social Housing (SH), in which characteristics of solar orientation, thermal envelope, and the installation of an EAHE will be modified, combined, and investigated in the proposed models. These evaluations were conducted through dynamic simulation with the EnergyPlus™ software. The results demonstrate that the installation of an EAHE in SH brings improvements in the thermal performance of environments, thus contributing that future projects can rely on validated references and parameters.

• A dynamic climate change impact evaluation framework is proposed. • Bamboo bio-concrete is a good climate change mitigation and adaptation alternative. • Bamboo bio-concrete presents a reliable carbon-thermal energy solution. • Bamboo bio-concrete provides a promising alternative for developing countries. This study aims to present a framework to quantify the climate change impact during the buildings' life cycle. The proposed framework is tested on a bamboo bio-concrete (BBC) building and compared with conventional constructive systems, in a Brazilian housing project considering six cities using Dynamic Life Cycle Assessment (DLCA) and thermal energy simulation. The increase of BBC in the building envelope, from 10 cm to 20 cm, leads to the improvement of carbon stock and reduces operational carbon. The BBC can be considered a potential alternative for climate change mitigation and adaptation and developed where bamboo is an available source. [ABSTRACT FROM AUTHOR]
