Estratégias de condicionamento térmico passivo para edificações de clima subtropical - Estado do Rio Grande do Sul

Abstract

This dissertation aims to search and present passive design strategies which could be used in buildings located in subtropical climate locations, focusing in Rio Grande do Sul, Brazil, where the temperature varies throughout the year with four welldefined seasons. Its focus is to find and demonstrate solutions including the thermal conditioning of environments since the architectural project conception, presenting to the client the best options on building wraps – combined to aesthetic quality – ensuring the comfort of the users and reducing the energy consumption with air conditioning. This study was prepared through bibliographic review of energy efficiency, passive architecture and climate characterization. It also searches and presents more appropriated passive design strategies for buildings in subtropical climate zones. The exposed results offer insights into strategies of air conditioning such as solar heating, natural ventilation and the thermal inertia. It also highlights more effective materials and construction techniques such as the use of double wals, the sealing of openings and penthouses, the implementation of green roofs and the use of Brise Soleil. These solutions, provided that they are in the project, will offer more comfort to the users with lower energy consumption over the building life.
