Indoor environmental quality index (IEQ) involves a set of IEQ sub components, provides an assessment of building user comfort and satisfaction and may be used as a tool to support the design of energy efficient buildings. Unfortunately, the unknown reliability of the IEQ model is a recognized barrier for its wider practical use. The measurement uncertainty based on the physical parameters is first analysed; then corrected by considering the impacts of the instability of the physical parameters. In the end, all sources of uncertainty are recognized, including uncertainties introduced by the probability distribution of panel sensory tests. A procedure for detecting internal incongruity in the IEQ model structure is also provided and a criterion for elimination of this syndrome is proposed. Finally in standardized indoor environment the estimated uncertainty of the IEQindex is presented to be no less than ±17%.

Wskaźnik jakości środowiska wewnętrznego (IEQ) definiuje elementy odczuwania poziomu komfortu i zadowolenia użytkowników budynku ze środowiska i może służyć jako narzędzie w projektowaniu budynków energooszczędnych. Niestety nieznana wiarygodność modelu IEQ stanowi barierę jego szerszego zastosowania. W artykule przedstawiono schemat analizy wiarygodności modelu IEQ, zawierającej oszacowania niepewności pomiarów parametrów fizycznych środowiska następnie skorygowane, przez uwzględnienie zarówno wpływu niestabilności tych parametrów jak i specyfiki panelowych badań sensorycznych postrzegania przez ludzi elementów środowiska. Podano również procedurę wykrywania sprzeczności wewnętrznej w strukturze modelu IEQ i zaproponowano kryterium eliminacji tego syndromu. W znormalizowanym środowisku wewnętrznym szacunkowa niepewność IEQindex będzie niemniejsza niż ±17% odsetka niezadowolonych.
