Abstract

Human activities have caused an excess of energy consumption. Buildings correspond to a considerable part of the electricity consumption, in special office buildings, which commonly have an air-conditioning system to provide thermal comfort. Many strategies have been studied to ensure energy efficiency for those buildings, such as the hybrid ventilation system, also known as mixed-mode system. A first literature review showed discrepancies between the expected and the real performance of mixed-mode buildings, in particular to Brazil's circumstances. This research intends to investigate the impacts of natural ventilation strategies on thermal and energy performance of mixed-mode office buildings, focusing on comparative analyses between single sided and cross natural ventilation. A field survey will be performed, in order to collect information about architectural design strategies of mixed-mode office buildings located in the city São Paulo, Brazil, which will be kept in a database. From the database, a detailed analytical study of five projects and two reference computer simulation models will be built - one provided with single sided ventilation and the other provided with cross ventilation. As a result, we intend to compare the thermal and energy performance of both ventilation strategies and discuss the thermal performance and energy consumption reduction potential for each analyzed strategy, considering industry restrictions.
