Course detail

Environmental Engineering

FSI-ITP Acad. year: 2023/2024 Winter semester

On average, people in developed countries spend more than 90% of their time indoors (buildings, vehicles, etc.). The course is focused on environmental technologies, i.e. technologies for creating healthy and comfortable indoor environments. These issues include thermal comfort, indoor air quality, ventilation, heating, air-conditioning, energy conservation, and basics of engineering acoustics.

Language of instruction

Czech

Number of ECTS credits

6

Department

Entry knowledge

Practical knowledge of mathematics, physics, thermodynamics, heat transfer and fluid mechanics.

Rules for evaluation and completion of the course

The written exam consists of theoretical and practical part. The theoretical part is a multiple choice test. The practical part includes solving one task. The theoretical and practical parts have equal weights for exam grading.
Attendance at seminars is obligatory. Condition for granting the credit is proper completion of exercises. In justified cases, the absence can be compensated by elaboration of individual tasks in the area of solved problems (tasks are assigned by the teacher).

Aims

The course addresses technologies for creating healthy and comfortable indoor environments with a special focus on minimizing energy consumption. Students get familiar with basic design and computational procedures in various areas of indoor environmental engineering.
Students get familiar with the technologies for creating healthy and comfortable indoor environments. Students also learn basic design and computational procedures in various areas of indoor environmental engineering.
