Extreme natural or man-made disasters are events caused by factors that injure, displace people and damage property. Victims of such events are often forced to live in temporary emergency shelters for prolonged time. It is therefore important to evaluate the indoor environmental quality in emergency shelters, which is the objective of this project. In addition to literature review, this project includes testing and integration of sensing modules that will be installed inside and outside of different emergency shelters in Fribourg (Switzerland). The sensing instruments will be able to detect a bouquet of air quality factors (CO2, VOC, NOx, SOx, PM2.5, PM10, O3), dry-bulb and globe temperature, noise levels, pressure differential, wind speed and illuminance levels.
