Equitable Urbanism integrates sensory elements into the urban landscape of Barcelona, Spain. By tackling the issue of thermal comfort and safety, diverse and active communities are supported through inclusive and considerate public space.
The implementation of botanic gardens serves to provide sensory stimulation, fixtures for play, and shade creating cooler temperatures, social engagement, and reduced heat risk.
JAMO is a sensor platform created for use with Arduino Uno that collects temperature, light, and humidity data.
The user turns JAMO on and simply walks through a site. JAMO then collects environmental data and writes it onto an on-board SD card as comma separated values.
The data is paired with an athletic 'track my run' phone app to provide GPS coordinates.
Using Microsoft Excel, both data sets are input into Rhinoceros and Grasshopper.
The output is a data driven visualization of existing environmental conditions.

DESIGNING WITH DATA!
Spain experienced three heat-waves in the summer of 2003 that led to a higher than projected mortality rate. The mortality rate in Barcelona alone rose 17.05% above average.
With 21.6% of Barcelona's population 65 years of age and older, the aging at risk population continues to grow. It is projected that in 2029 a quarter of the population will be over 65, and by 2064, 38,7% of the population will be over 65.

Botanic Street Gardens utilizes a reactive cooling system of in-ground fountains to cool spaces via evaporation. Passive cooling strategies are also employed via tree shade and foliage cover.
The primary goal is to engage communities with spaces that provide sensory stimulation and appropriate autonomy. By creating cool accessible spaces, those at risk of heat related illness such as seniors and children have a place to gather during all times of the year.
