Computational fluid dynamics simulation of indoor carbon dioxide concentration in rooms in the residential building Available to Purchase

A proper indoor environment in residential buildings is crucial for the occupants comfort. Several studies have analyzed the impact of the increased CO₂ concentrations on indoor air quality (IAQ) complaints and health symptoms in buildings. Many recent studies have shown that non-residential buildings have significant indoor environmental problems, while ventilation levels are below the recommended rates. It is found that air flow rates below 10 l/s and increased IAQ and health symptoms among the occupants. Magnitude of the outdoor air flow to the room, in the residential buildings, determines EN-15251 Standard. This article presents the numerical simulations of mixing carbon dioxide generated by people with air distributed by the system of mechanical ventilation to the rooms in the residential building.
