Abstract

This paper presents the results of the measurements and simulation of carbon dioxide concentration, as an indicator of indoor air quality, inside the master bedroom of an inhabited passive house. The measurements were taken in the autumn for a period of ten days. A series of sensors placed inside of the test object wirelessly measured the contaminant concentration every thirty seconds. The measurements were taken continuously in real time, when the occupants freely used the household. The contaminant concentration shows the impact of their activity on the air quality, as they were the only indoor air source of CO2. During the measurements, the ventilation system that the house was equipped with was manually controlled by the users according to their daily routine. Simulations were performed to determine if it was possible to recreate the measured conditions within the bedroom of the passive house. The chosen program was the CONTAM software application, a tool designed for indoor air quality and ventilation analysis, developed by NIST.
