Premeasurement and Analysis of the IAQ Parameters

Abstract

Indoor Air Quality is one of the most essential factors for ensuring a healthy and comfortable environment inside the buildings. In order to obtain precise and reliable measurements for IAQ, it is necessary to implement a pretesting phase and to perform an analyze of the the data resulted before using the measurement device Testo, according to standards: ISO 7730 and ASHRAE 55. Pretesting is important to identify and eliminated possible errors or external factors which can influence in the end the measurement data all of this so the quality of the data can be improved. This paper aims to analyze a data series of IAQ measurements by using a measurement device, special dedicated for monitoring and evaluation of different ventilation systems. Data taken out of the monitoring phase is processed and the results show the issues with the existing air ventilation systems as well as the potential improvement solutions for the identified nonconformities. The usage of the standards ISO 7730, ASHRAE 55 and Testo measuring device has a big potential in assuring good and reliable measurements of the IAQ. It is important to highlight the importance of pretesting phase and the analyze of the measurement data in order to ensure a good evaluation and finally a sum of solutions focused on providing healthy and comfortable environments.
