| Course abstract | |
| The course paper aims to gain knowledge of the heating and ventilation systems at residential buildings. Structure and parts of the ventilation systems. Some basic methods of calculation and design are needed for the proper operation of the systems. | |
| Learning outcomes and their assessment | |
| After course acquisition students must be able to make the right decisions in assembling heating, ventilation, and air conditioning system elements, calculations of them, to assess the consequences of wrong operation of systems, planning of right sequence of works, safety and quality control of works. Defending the course project presented in the LBTU e-studies. • Knowledge about microclimate systems for residential buildings, their structure, components, and preconditions for proper functioning; • Skills to calculate simple engineering systems, selection, and calculation of main equipment and energy resources; • Competence in the field of water, steam, air, gas, electric and heat pump heating systems of the buildings and ventilation. | |

| Requirements for awarding credit points | |
| Course projects have to be defended. | |
| Description of the organization and tasks of students’ independent work | |
| After receiving a task for the independent course project, students need to get acquainted with the content of the assignment and the work plan. Drawings of the building should be checked to understand the building structure and division of premises fully. Students should study the normative literature and manuals required for the work. By completing an independent course project, students must acquire skills to make simplified calculations in the areas of heating, ventilation, and air conditioning in buildings. | |
| Criteria for Evaluating Learning Outcomes | |
| Skills for practical use of theoretical knowledge in the design of heating, ventilation, and air conditioning systems of the buildings - choosing the rational and effective solutions of the systems and the choice justification. Evaluation of capabilities to analyse the project solution. Skills to choose heating, ventilation, and air conditioning solutions for specific buildings. Knowledge of the requirements of LBN and MK regulations in the areas of heating, ventilation, and air conditioning: https://likumi.lv/ - LBN and MK regulations for heating, ventilation, and air conditioning and knowledge of their changes. The course project is judged to be excellent if the lecturer does not show any unfulfilled claims and the student correctly answers all 6 questions; excellent if the score for the 6 questions is greater than 50; very good if the score is over 45; good grades receive course projects with a score greater than 40; almost good if the score exceeds 35; average if the score exceeds 30; almost average if the score is over 25, but course projects with 25 errors are judged unsatisfactory and the student is given a new course project assignment. A course project with less than 25 errors may try to defend in response to 6 questions. | |
