Investigation of indoor air quality and its impact on human activity - case study

Abstract

This paper presents the partial results of human presence impact on indoor air quality in a monitored office room. Indoor air temperature, relative humidity and carbon dioxide concentration are recorded in the investigated room during the operation. Simultaneously, the heartbeat (pulse) and blood pressure of respondents are determined. During the measurements, the investigated room was occupied only by one person. These measurements were repeated several times. Respondents were of different sex, different weight and different age. Measurements were carried out during activities: sedentary office work using computer, exercises for squat and exercises on the stationary bike. The aim of the research work is to determine the relationship between the activities and the determined mentioned factors. Measurements of the heartbeat and blood pressure of respondents were realized in order to investigate the impact of their variation on perceived indoor air quality. The obtained boundary conditions will have a positive contribution to a healthy indoor environment. It can be concluded that the carbon dioxide concentration, measured or calculated inside a room, is the most appropriate parameter of indoor air, based on which the ventilation equipment must operate in order to ensure the indoor air quality. Optimally placed air quality devices and sensors and an appropriate automation system can effectively maintain the indoor air quality at comfortable levels.
