Measurements and simulation of CO2 concentration in a bedroom of a passive house

Abstract

W artykule przedstawiono wyniki pomiarów i modelowania stężenia dwutlenku węgla, jako wskaźnika jakości powietrza wewnętrznego, w  sypialni zasiedlonego domu pasywnego. Pomiary prowadzono w okresie jesiennym, nie zaburzając normalnego cyklu życia domowników. Umieszczone wewnątrz obiektu testowego czujniki w sposób bezprzewodowy mierzyły poziom stężenia zanieczyszczenia co 30 sekund, przez okres dziesięciu dni. Pomiar był dokonywany w sposób ciągły, w warunkach i czasie rzeczywistym, gdy mieszkańcy swobodnie poruszali się wewnątrz budynku. Poziom stężenia dwutlenku węgla odzwierciedlał wpływ aktywności mieszkańców na jakość powietrza wewnętrznego, gdyż byli oni jedynym źródłem CO2 w obiekcie. Podczas pomiarów instalacja wentylacyjna, w którą dom został wyposażony, była włączona i regulowana przez domowników według wypracowanego przez nich schematu. Przeprowadzone symulacje miały na celu określenie czy możliwe jest odtworzenie warunków zmierzonych w sypialni analizowanego budynku. Do modelowania wybrano oprogramowanie CONTAM, narzędzie przeznaczone do analizy systemu wentylacji i jakości powietrza wewnętrznego, opracowane przez NIST. 

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
