The modern buildings are becoming more and more different from the traditional buildings, especially regarding their parameters of the indoor environment and low energy performance. For this reason, the real estate market has been looking for new criteria to estimate their market value and to distinguish them one from another. As they are trying to find the most objective parameters for establishing the market value of the buildings on the real estate market their attention focuses also on the quality of the indoor environment. The real estate market perceives a building with high quality of the indoor environment traditionally in the context of the technical, economic and energetic parameters but with higher and higher emphasis also put on social and environmental connections [1,2]. This paper is focused on the analysis of how much the quality of the indoor environment is taken into account in the process of the market valuation of the buildings in modern context.
