Abstract
The quality of indoor environment is an extremely important issue, because people spend large parts of the day inside buildings. The quality of the indoor environment is largely dependent on the quality of indoor air. The parameters of the air we breathe affect our health and comfort of room use. Currently, when energy efficiency is a priority, it is difficult to maintain comfort and conditions appropriate for human health. The artificial environment in a room and related inadequate air quality cause many diseases, such as asthma, lung diseases, cardiovascular diseases, as well as poor well-being and reduced productivity. The Disability Adjusted Life Years (DALY) indicator means “loss of life corrected by disability” and is widely used by the World Health Organization to measure a disease burden on the population and identify the causes of a disease. The aim of the article is to present the structure of the DALY indicator and its suitability to assess the impact of indoor air quality on human health. The most frequent diseases caused by low quality of internal air were analysed based on statistical data. In addition, the possibilities of ventilation solutions have been presented, leading to the improvement of air quality in indoor environment.
Highlights
The quality of indoor environment is a very important issue, because users of rooms spend a significant part of the day inside buildings, not being aware of health and well-being implications
Other causes of diseases associated with low air quality are tobacco smoke (4%), bioaerosols (3%), volatile organic compounds (VOC) (1%) and carbon monoxide (CO) (1%)
Disability Adjusted Life Years (DALY) is used to diagnose the main causes of disease, it is important in the area of health protection
Summary
The quality of indoor environment is a very important issue, because users of rooms spend a significant part of the day inside buildings, not being aware of health and well-being implications. Striving to achieve the highest possible insulation of buildings results in limiting the natural exchange of air between the internal and external environment. The air quality in buildings is considered with regards to health protection and comfort of room users It is shaped both by physical and chemical parameters, which make the interior microclimate - an ecosystem that allows the formation of favourable conditions for people. − analyse method of air exchange and movement, both inside and outside the building, − examine ratio of permeability of partitions to the amount of impurities, − determine mutual influence of impurities of physical and chemical nature, affecting the degree of their concentration. The indoor environment and its microclimate has the strongest effect on human well-being, health and productivity. [4, 6]
