The building sector with the highest energy consumption is also a priority area in which the possibilities of solving environmental and economic problems are great. Achieving benefits from the energy, environmental and economic aspects, can be achieved by using renewable energy sources whose implementation does not require large and expensive interventions on facilities. One such possibility is the passive use of solar energy to achieve a higher level of energy efficiency. The paper will present the basic concepts necessary for understanding the topics and research related to solar energy, energy consumption of residential buildings, the use of the Trombe wall as a heating system and extensive green roofs as a natural insulator of buildings. Accordingly, the paper describes and comparatively analyses three possible solutions to achieve a higher level of energy efficiency of a residential building, through the implementation of 3 scenarios: thermomechanical measures, Trombe wall and extensive green roof. The positive impact of this type of using the alternative solutions, has other advantages: reducing greenhouse gas emissions, achieving more favorable microclimatic conditions of built environment (preventing heat island) and the preservation of the environment and the health of modern man.
