French multidisciplinary consultancy firm AREP has developed an urban cooling structure that ticks all the sustainability boxes—it is low-tech, energy-efficient, resource-friendly and affordable.
Vietnam is no stranger to heatwaves, which the country combats with air conditioning units. These units leak coolant gas into the environment, creating a positive feedback that exacerbates climate change. AREP's hyperboloid bamboo tower uses the adiabatic principle to naturally cool water and, subsequently, the surrounding air.
AREP hopes that similar cooling structures can be used in places with dryer climates, such as areas surrounding the Mediterranean basin. Some examples include public squares, unsheltered pedestrian streets and train stations.
