Abstract

The subject of this paper is a detailed analysis and evaluation - audit of the quality of the indoor environment in the reference zone of a primary school building in the Czech Republic. The analysis and subsequent evaluation is performed by the certified CTU HAIEQ (Holistic Assesment of Indoor Environmental Quality) methodology, developed at the Department of Building and Construction Engineering of the Czech Technical University in Prague. The analysis is based on a detailed survey of the building, measured data of physical variables of the indoor environment and subjective assessment from the user's point of view. The evaluation of the quality of the environment is carried out in 8 categories - LS Location and location of the building in terms of external environment and social connections; STI Structural-technical design and interior of the evaluated zone; TCW Thermal comfort in cold season; TCS Thermal comfort in warm season; IAQ Air quality; LC Light environment; AC Acoustic environment and EC Electro-magnetic, -ionic -static fields. Each category has 5-8 criteria to be evaluated. The outcome of the indoor environment audit using the HAIEQ methodology is the identification of critical areas and the proposal of possible measures to improve the current situation. The implementation of the proposed measures must be carried out in accordance with applicable regulations and laws by authorized persons. The method used does not guarantee that all problem areas will be found using it and the preparer is not responsible for problems not found during the analysis of the building. The results of the measurement and evaluation methodology are not a substitute for an assessment by a sanitary service.
