Description of the organization and tasks of students’ independent work

After receiving the task of the independent course project, you should familiarize yourself with the content of the task and the work execution plan. Construction drawings of the building must be developed in order to fully understand its structure and the distribution of rooms. Familiarize yourself with the standards, regulations and manuals required for work. By completing the independent course project, students should learn the skills to perform simplified calculations in the areas of heating, ventilation and air conditioning of buildings.
After completing the course, students should be able to complete the heating, ventilation and air conditioning system, perform its calculations, assess the possible consequences of incorrect operation of the systems, plan the sequence of system construction works, safety and quality control. Defense of the course project submitted in LBTU e-studies.
