Course developer

Prior knowledge

BūvZ6042, Building Physics Sspecial Course

Course abstract

Students gain knowledge about the energy audit procedure of buildings, methods, activities to be included, necessary measuring instruments, equipment. Students must learn the principles of energy efficiency assessment for residential, public and industrial buildings. It must be possible to analyze specific technological processes that take place in production buildings.

Learning outcomes and their assessment

After the course studies the student will have:
• knowledge of the procedure for conducting energy audits of buildings and technologies
• skills to assess the energy efficiency of buildings and production processes
• Competence on indicators affecting the energy efficiency of a building

Requirements for awarding credit points

Developed and successfully defended individual work. Successfully passed the test with a mark.

Description of the organization and tasks of students’ independent work

The student independently gets acquainted with the Law on Energy Efficiency of Buildings and regulatory enactments subordinate to these laws on the application of State Standards in the performance of energy audits of buildings.
The student individually develops individual work (inspects the building and its engineering systems, performs calculations, prepares a building energy certificate and energy audit report) according to the course content.

Criteria for Evaluating Learning Outcomes
