We’re on a mission.

Heatwaves can be deadly to vulnerable populations, such as the very young, the elderly, and pregnant women, and are anticipated to be a serious threat to city life in the near future. The World Health Organization has tracked hundreds of thousands of deaths from heat waves affecting cities around the globe and estimates that an additional 250,000 lives could be lost each year between 2030 and 2050 due to the increasing temperatures.

Protecting those most at risk for ill health and death related to heat exposure means cooling the buildings in which they reside. However, current cooling systems worsen the climate crisis by using significant amounts of energy and increase the already rising temperatures of urban heat islands by emitting substantial heat locally. Passive daytime radiative cooling (PDRC), in which technology mimics nature by finding ways to stay cool without significant energy input, has long been a holy grail of the climate change solution. At Pirta, we are proud to announce that our technology is a means of PDRC that is affordable, easy to use, and most importantly, effective. Pirta is passive cooling.
