The aim of the course is to acquaint the students with the building and environmental aerodynamic phenomena and problems occurring in engineering practice, their investigation methods. Significant emphasis is placed on the study of wind effects on buildings and engineering structures using wind tunnel measurement techniques, in addition to the issues of urban climate, wind comfort and the spread of atmospheric pollutants. The course also describes the characteristics and requirements of the application of flow numerical simulation (CFD) in this field. During the preparation of a group project task, students are introduced to the use of one of the above-mentioned research methods.

It strives for a thorough acquisition of environmental and building aerodynamic knowledge. He strives for active participation in the lecture, for interactivity. He / she independently expands his / her knowledge on the topic of the chosen semester task by processing the literature. Supports your classmates in solving a measurement or simulation group task. It strives to complete the task on schedule, to overcome existing obstacles. Expands your knowledge for demanding, high-quality, precise presentation of measurement / simulation results in the task report.
Independence and responsibility
Collaborates with the instructor and fellow students to expand knowledge. He feels a responsibility for an in-depth understanding of the issues surrounding environmental and building aerodynamics. They are responsible for the completion and quality of the joint task. If necessary, direct the work of the group during the (partial) task. Accepts critical remarks about the work done.
The teaching of the subject takes place in the framework of lectures and laboratory practice. The lectures basically introduce the students to the information determined by the knowledge competence elements using the technique of frontal education. During the second half of the semester, several invited industry speakers will give lectures on each chapter of the topic. The application and skill-level acquisition of knowledge takes place in laboratory exercises, where an issued project work has to be solved in groups, which also develops teamwork skills. The project work must be presented at the end of the semester in the form of a written report and a presentation. In addition, one or more laboratory demonstrations / demonstration measurements will take place.

Validity of the course description
|Start of validity:||2020. March 3.|
|End of validity:||2024. December 31.|
Learning outcomes are assessed on the basis of a mid-year written summary performance measurement as well as a partial performance measurement. Summative academic performance appraisal is a complex, written way of assessing the knowledge and ability type competence elements of the subject in the form of an in-house dissertation, which requires the necessary lexical knowledge during the performance appraisal, the available working time is 90 minutes. Partial performance assessment (homework): a complex way of evaluating the knowledge, ability, attitude, as well as independence and responsibility type competence elements of the subject, the form of which is the homework prepared in groups.
Detailed description of mid-term assessments
|Mid-term assessment No. 1|
|Purpose, description:||Cumulative performance evaluation (in-house), which is expected to take place in the 8th week of education. 50 points can be obtained in the summary performance evaluation. A minimum of 40% is achievable. The aim of performance appraisal is to check the acquired knowledge and ability competencies with theoretical, short essay questions and simple practical numerical examples. The performance evaluation covers all the knowledge materials given in the lecture until the 7th educational week.|
|Mid-term assessment No. 2|
|Type:||formative assessment, simple|
|Purpose, description:||The method of partial performance evaluation is the preparation of a project task to be prepared in groups, followed by a presentation of the subject to the students. Assignments and assignments for groups of up to 4 should be finalized by the second week of education. The content and form requirements and evaluation principles of the prepared project dissertation are included in the terms of reference. It will be completed on the date specified in the study performance assessment plan, expected to be in the 14th week of education. A maximum of 50 points can be obtained with the task, a minimum of 40% can be achieved.|
