Optimizing Needs Fresh Air for Healthy Microclimate

摘要

The aim of the experiment was to verify the CO_2 concentration in the indoor environments in different flows of fresh air per person, based on the legislative requirements of the Czech Republic and the European Union. The experiment was performed in a passive house at the Faculty of Civil Engineering, VSB - Technical University of Ostrava. Legislative requirements regarding minimum fresh air flow (25 m~3/h) according to the measurements do not comply with the recommended limits on CO_2 concentration of the valid legislation. The paper analyzes the impact of variable fresh air flow on CO_2 concentrations in the interior of building. The article describes the method of the experiment and evaluate the results of the real test.
