“…Taking into account the regulatory requirements for ventilation in apartments in MABs and actually completed unrenovated building energy audit inspection data, which suggest an increased omitted air infiltration through gaps [11], it can be predicted that CO2 concentration level in the existing building indoor air should be according to the recommended standardsup to 1000 ppm [12], [13]. However, inspection and measurement data show that increased air infiltration in local building construction defect places (along the window frames, panel seams) does not enhance the effective natural ventilation of apartments [14]. As a result of increased heat losses in buildings, indoor climate does not provide healthy and comfortable conditions for humans as determined by the standards.…”

The article summarizes the IAQ parameters of multi-apartment buildings before and after renovation in Latvia. In a building with natural ventilation system air exchange is significantly dependent on the position of the apartment within the building. If CO2 as an indicator of indoor air quality is analyzed, the results show that inhabitants' behavior has a considerable impact on IAQ. The planning of adequate investment in buildings to improve energy efficiency and choosing the modern, adequate and effective engineering solutions, it is possible to raise the comfort level of living space and to reduce heat and thermal energy consumption.
