The subject of this paper is a description of the method of construction, the possibilities of energy saving, the description of the used renewable energy sources and the amount of reduction of harmful gas emissions, the passive construction method in relation to the classic method of construction. At the beginning of the paper, we talk about energy production, its impact on the environment, and the construction of passive buildings. The continuation shows an overview of energy sources and a more detailed description of renewable sources used in passive construction. Further, the calculations of primary energy consumption and the system for its distribution for the passive building of this project are given. The final part refers to the ecological awareness of the construction of passive buildings in order to reduce energy consumption, i.e., emissions of harmful gases compared to the classic construction method shown by the economic analysis of the project. At the very end, a conclusion is given.
