HYGIENIC PARAMETERS CHARACTERIZING THE MICROCLIMATE OF THESE ENCLOSED SPACES

Abstract

Human health and work capacity are largely determined by microclimatic conditions and air quality in residential, public, and industrial buildings.
The importance of this issue is further emphasized by the fact that people spend a significant portion of their time indoors—according to some data, up to 95% of the day. An analysis of the current regulatory and methodological documents in the field of indoor microclimate, along with a review of laboratory and instrumental testing reports submitted to the Inspection Body for evaluation, identified the following key issues: The regulatory and methodological documents (RMDs) currently in force in the field of indoor microclimate are focused solely on ensuring compliance with permissible microclimate parameters. These documents contain inconsistencies and shortcomings, including the absence of a regulated lower limit for acceptable relative humidity, the representation of the standardized humidity range by a single value, discrepancies between the requirements of different sections of the document, and issues related to requirements for measuring instruments, among others. There is no clear description of the methodology for determining the resultant indoor temperature and, consequently, the local asymmetry of the resultant temperature. The issue of  regulating microclimate parameters in preschool educational institutions requires particular attention and discussion. The sanitary norms and regulations specify only the ranges of air temperature and relative humidity (without indicating optimal and permissible values) and do not provide standards for air velocity or resultant room temperature, which makes it impossible to conduct a comprehensive assessment of microclimate parameters.
