The main goal of this final work is to show how smart architectural and construction solutions can be used to solve the problems that we, as well as the whole world, are facing. Shortages of energy sources as well as their high prices have encouraged the development of passive houses. The construction of passive houses implies high energy efficiency, health and comfort of residents and reduction of negative impact on the environment. In order to successfully achieve the above, a number of principles and standards have been prescribed that designers and contractors must adhere to. A passive house meets its energy needs by using solar energy. Adequate orientation, smart layout of rooms, compact building shape, quality glazing and quality thermal insulation are just some of the factors that enable us to make the most of solar gains, while minimizing heat losses. In addition to financial profitability, the high quality of life that can be achieved through passive construction is one of the main reasons why investors choose such solutions. This final paper gives a brief insight into the historical development of passive houses, while emphasis is placed on the design principles and standards, which are additionally shown on the derived examples.
