Course abstract

The aim of the course is to learn the choice of building heating ventilation and air conditioning solutions, skills in designing simple heating, ventilation and air conditioning systems, understanding of equipment structures and project documentation. By developing the course project "Heating and ventilation of a residential building", students gain knowledge about systems for ensuring the microclimate of residential buildings, their structure, components and contraindications for proper operation. Students also learn the calculation methods of simpler engineering systems, the basic principles of selection and calculation of main equipment and energy resources.

Learning outcomes and their assessment

Students know how to practically use theoretical knowledge in the design of building heating, ventilation and air conditioning systems - in the selection of rational and effective solutions of systems with their justification. Assessment of project solution analysis abilities in the exam.
Students know how to choose heating, ventilation and air conditioning solutions for buildings of specific importance. Assessment in the exam.
Students develop skills and competences in the requirements of LBN and MK regulations in the fields of heating, ventilation and air conditioning. Assessment of knowledge in the course project defense process.

Requirements for awarding credit points

The course project must be defended and the exam must be successfully passed.

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.

Criteria for Evaluating Learning Outcomes

Course job will be assessed in 10 point system depending of explanatory article information rightness and fullness, quality and correctness of graphic drawings.
