The Environmental Performance Of Temporary Urban Interventions: Technical Assessment Of Regeneration Initiatives In The City Centre Of São Paulo, With Focus On Thermal And Acoustic Performance

Temporary urbanism is an approach to reactivate urban spaces through short-term interventions in a range of urban contexts. In central São Paulo, the Luz and Santa Ifigênia neighbourhoods, characterized by deprivation of their physical environments and social structures, were the focus of this investigation. The Mungunzá Container Theatre and the General Osório Square, located within these neighbourhoods, were selected as case studies. Whilst the thermal performance of the container theatre itself was the main interest, in the case of the Square the fundamental issue was the environmental noise. The objective was to identify adequate strategies to improve environmental conditions in these locations in order to enhance positive social impact, and, then, contribute to the regeneration of these neighbourhoods. This research was based on fieldwork and analytical procedures of thermal and acoustic performances. In the container theatre building, the adoption of external shading and wider openings for ventilation reduced its indoor peak temperatures and delivered thermal comfort during the warmest period of the year. In the Square, sound absorber road surface material and an acoustic shell were proposed to reduce noise and promote better acoustic quality for outdoor performances.
