According to the prediction from 2000 to 2020, the number of people over the age of 65 will be increased from 16 to 20 %. In this case, the elderly people spend approximately 19–20 hours a day in the rooms. This circumstance indicates the importance of studies dedicated to the assessment of the environment conditions in the residential premises, particularly the formation of the comprehensive assessment of thermal comfort and indoor air quality. The need is shown concerning the formation of the general index of the environmental quality in the rooms, which considers both thermal comfort and air quality.
Classic example of the air quality assessment is US EPA index determined by linear interpolation of factors such as O3, PM10, PM2.5, CO, SO2, NO2, and, which allows to form seven levels of air pollution hazard for the human body. The main disadvantages of the air quality index are: neglect of air pollutants such as CO2 and formaldehyde; neglect of causes and consequences of global warming in terms of the dynamics of temporary increase in the concentration of CO2 in the air; impossibility of considering EPA index in the complex dynamic indices, which take into account temporal development of individual assessments of the influencing dynamic factors.
The objective of the article is to study the possibility of formation of the new dynamic environmental index for residential and industrial premises, combining both the partial assessment of growth dynamics of CO2 concentration in the air, and the thermal comfort index, which takes into account the rise in average temperature on the planet due to increase of CO2 concentration in the atmosphere.
Multiplicative quality criterion of the environment is proposed, which considers the trend time of CO2 concentration in the atmosphere. It is shown that the proposed index retains the main positive properties of the Fanger comfort index, i.e. it is reset to zero at complete comfort and allows to determine the degree of discomfort of people staying in the room by way of calculating non-zero value of the entered index.
