| Summary |
|---|
The subject deals with building thermal technology and the energy demand of buildings in connection with smart energy (smart grid) of cities. Students will become familiar with calculation methods for evaluating the energy efficiency of buildings, energy evaluation of the operation of heating and ventilation systems, systems for the preparation and distribution of domestic hot water, lighting systems, pumps and fans, cooling systems, technological equipment and other energy consumers, with the principles of digitization of distribution energy networks in smart cities.

| Learning Outcomes of the Course Unit |
|---|
| The student will acquire basic knowledge and skills in the field of energy efficiency assessment of individual buildings in connection with smart energy (smart grid) of cities. They will learn to assess construction structures and buildings according to the requirements of the applicable legislation in the given area. Can solve computational tasks using special software. The student will acquire the skill to design and assess different types of buildings for their energy efficiency, determine the certificate of energy efficiency of buildings, and propose improvement measures. The student will learn about the principles of a decentralized energy system in smart cities using elements of artificial intelligence to predict energy flows. |
