Previous research and statistical data have shown that buildings in Europe consume about 40% of total energy, and most of it is spent on heating. Due to the use of fossil fuels, many harmful gases are emitted into the atmosphere, especially greenhouse gases. Therefore, the study of new technologies and solutions in the field of construction of housing and other facilities is a priority task that is inevitably set before experts in this field. In addition to the need to optimize the envelope of buildings to reduce energy consumption, there is also a need to preserve the environment, in terms of reducing emissions, preventing the formation of heat islands and air purification. For these purposes, specific green systems are used, in the form of vertical greenery systems (green walls and facades), as well as green roofs. The biggest role in achieving the energy efficiency of a building is its envelope. This paper deals with the study of innovative technologies for materialization of building envelopes that contribute not only to the achievement of energy optimization, but also to environmental protection. Because of this concept of urban development and design, the possibility of reducing the consumption of fossil fuels has been analyzed, which would greatly reduce the negative effects of climate change, as one of the aspects of achieving sustainable cities and communities.
