ABSTRACT

Contemporary design, realization and operation of buildings based on cost-effective energy savings have an impact on the quality of the indoor environment. We meet completely new questions about the indoor environment quality in buildings with high-energy performance in terms of thermal comfort, air quality, acoustic, light, electro-magnetic, -ionic, microclimate and psychological comfort. The aim of the “Smart Regions Competence Centre” project of the Czech Republic’s Technology Agency is, among others, to introduce a methodology for expressing the quality of the indoor environment in low-energy buildings. The reason for this project is the fact that clients are currently receiving detailed information only on the energy performance of the building – energy certificate – but they have virtually no information on the real or expected quality of the indoor environment in buildings. The methodology is based on a holistic approach to integrate data from smart building control systems, short-term monitoring campaigns and a questionnaire survey among users. In the case of new buildings, the assessment is based on the simulation of the energy performance of buildings. The use of the methodology is documented on the results of long-term monitoring of selected IEQ indicators, energy performance and questionnaires in nZEB buildings.
