BUILDING DESIGN, COMFORT AND HEALTH: an urban refuge for heat waves Bianca Bonachela de Oliveira (Diploma student) Professor Denise Helena Silva Duarte (Advisor) Research: Diploma Project Research period: 2020/08 - 2021/08 2021/APRIL
Reason for interest in the subject: URBAN CLIMATE & ARCHITECTURE AND URBANISM Research Group: Study of the positive impacts that vegetation (evapotranspiration process and shading) provides to the urban microclimate 2 years of scientific initiation: Urban Plans Regulations for land use and occupation
How do cities around the world plan to implement the vegetation of the densest urban environment? Do the plans or policies mention any relationship between green and the microclimate, urban climate or climate change?

Adaptation minimize impacts ( in a short term)
“Cooling centres”
changing habits and adapting to the new reality (long term) + green infrastructure
The problem
Heat waves and its reflection in human health:
Frequency of heat waves in the city of São Paulo

What is considered a “heat wave”? - 3 consecutive days with maximum temperatures above the expected for a certain region during a certain time of the year. (GEIRINHAS et al, 2017) How does it affect the human body? (“Heat related illness”) - Intense heat affects the thermoregulatory system, aggravating cardiovascular and respiratory diseases or causing deaths by hyperthermia, especially among the elderly and children. (DINIZ et al, 2020) Increase of deaths - France (2019): Agnès Buzyn, French Minister of Health, reported the was increase of 9.1% on the average of deaths during the summer (heat waves).
Green Corridors
Adaptation I Link between remnants of native vegetation
the insertion of vegetation is defended through more “technical” arguments
"Breathe" / Urban "Empty" (wind currents)

“Cooling Centers” What is it ? - network of public or private buildings with air conditioning systems that allow free access to the public during heat waves events.

Questions: - Why not encourage public equipment projects that are intertwined with green area projects? - Why not try to develop of an architecture with a good thermal performance basing in the choice of its materiality, design or natural ventilation instead of encouraging the use of air conditioning systems?
Diploma’s project idea: Why not propose a “cooling center” for São Paulo connected with a green corridor?

Definição de Cooling Centers
Architectural program
(...) ” is a location, typically an
air-conditioned or cooled building that has been designated as a site to provide respite and safety during extreme heat. This may be a government-owned building such as a library or school, an existing community center, religious center, recreation center, or a private business such as a coffee shop, shopping mall, or movie theatre. Some counties have set up cooling sites outdoors in spray parks, community pools, and public parks. Sometimes temporary cool spaces are constructed for events such as a marathon or outdoor concert. “ “Center for Disease Control and Prevention” (CDC) - USA https://www.cdc.gov/climateandhealth/do cs/UseOfCoolingCenters.pdf
SESC Program is based in 5 premisses:
educação cultura lazer saúde assistência
Why not try to create :
Culture House Community pools and public park Health Basic Unit (UBS) Mental health clinics, dentist, nutritionist etc. (support to UBS)
