A comparative study of indoor environmental quality in temporary emergency shelters

Patrick Bonzi
2020
Student project
Abstract

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.

Wet-bulb temperature
The wet-bulb temperature (WBT) is the temperature read by a thermometer covered in water-soaked (water at ambient temperature) cloth (a wet-bulb thermometer) over which air is passed. At 100% relative humidity, the wet-bulb temperature is equal to the air temperature (dry-bulb temperature); at lower humidity the wet-bulb temperature is lower than dry-bulb temperature because of evaporative cooling. The wet-bulb temperature is defined as the temperature of a parcel of air cooled to saturation (100% relative humidity) by the evaporation of water into it, with the latent heat supplied by the parcel.
Wind speed
In meteorology, wind speed, or wind flow speed, is a fundamental atmospheric quantity caused by air moving from high to low pressure, usually due to changes in temperature. Wind speed is now commonly measured with an anemometer. Wind speed affects weather forecasting, aviation and maritime operations, construction projects, growth and metabolism rate of many plant species, and has countless other implications. Wind direction is usually almost parallel to isobars (and not perpendicular, as one might expect), due to Earth's rotation.
Natural disaster
A natural disaster is the highly harmful impact on a society or community following a natural hazard event. Some examples of natural hazard events include: flooding, drought, earthquake, tropical cyclone, lightning, tsunami, volcanic activity, wildfire. A natural disaster can cause loss of life or damage property, and typically leaves economic damage in its wake. The severity of the damage depends on the affected population's resilience and on the infrastructure available.
