Abstract

The impact of ventilation efficiency on radon (222Rn) and carbon dioxide (CO2) concentrations in the indoor air of a residential building was studied by applying transient data analysis within the CONTAM 3.4 program. Continuous measurements of 222Rn and CO2 concentrations, together with basic meteorological parameters, were carried out in an apartment (floor area about 27 m2) located in Ljubljana, Slovenia. Based on the measurements, a transient simulation of 222Rn and CO2 concentrations was performed for six sets of scenarios, where the design ventilation rate (DVR) varied based on the ventilation requirements and recommendations.

Secondary abstract:	Vpliv učinkovitosti prezračevanja na koncentracije radona (222Rn) in ogljikovega dioksida (CO2) v notranjem zraku stanovanjske stavbe smo proučevali z nestacionarim modeliranjem s programom CONTAM 3.4. Kontinuirane meritve koncentracij 222Rn in CO2, skupaj z osnovnimi meteorološkimi parametri, so bile opravljene v stanovanju (površine približno 27 m2), ki se nahaja v Ljubljani, Slovenija. Na podlagi meritev je bila izvedena simulacija koncentracij 222Rn in CO2 za šest sklopov scenarijev, kjer se je načrtovana stopnja prezračevanja (DVR) spreminjala glede na zahteve in priporočila prezračevanja.
