Paradoxically, indoor air can be more harmful in an insulated, above-standard insulated apartment without a high-quality ventilation system than in an old building, where it blows due to leaks. To measure the quality of the indoor environment, we therefore chose more places, differing not only in location, but also in the method of insulation and ventilation techniques.
Measurement of carbon dioxide (CO2) and volatile organic compounds (VOC) or relative humidity and temperature values was designed to compare air quality in apartments in old buildings, prefabricated houses, new buildings and in energy-saving projects with an automatic system of controlled ventilation with heat recovery.
