Abstract
Kriging is an interpolation technique that is used to estimate a variable at an unmeasured location from observed values at nearer locations. In this study, it is used to analyze the spatial distributions of the health risk of indoor air pollution. The study case is an air-conditioned office building that has 16 floors, located in Taipei, Taiwan. The Kriging method is used in drawing health risk maps on the basis of limited sample points and facilitates investigating the possible source of pollution.
Highlights
Clean air is a basic requirement for human life
Indoor air pollutants that are defined in the Taiwan Indoor Air Quality Act include carbon dioxide (CO2), carbon monoxide (CO), formaldehyde (HCHO), total volatile organic compounds (TVOCs), bacteria, fungi, airborne particles with a particle diameter ≤10 μm (PM10), airborne particles with a diameter ≤2.5 μm (PM2.5), and ozone (O3)
CO2 can cause choking at high concentrations
Summary
Clean air is a basic requirement for human life. The indoor air quality of homes, offices, schools, health care centers, and private and public buildings is critical for human health because most people cannot be separated from these spaces. Some buildings, building materials, and interior equipment or even cooking and heating fuel combustion may release harmful substances that cause serious health damage. People spend approximately 80% - 90% of their time inside office buildings or other structures; poor indoor air quality can cause sick-building syndrome, directly affecting work quality and efficiency and negatively affecting health [1]. Indoor air pollutants that are defined in the Taiwan Indoor Air Quality Act include carbon dioxide (CO2), carbon monoxide (CO), formaldehyde (HCHO), total volatile organic compounds (TVOCs), bacteria, fungi, airborne particles with a particle diameter ≤10 μm (PM10), airborne particles with a diameter ≤2.5 μm (PM2.5), and ozone (O3).
