Course detail
Environmental Engineering
FSI-ITP Acad. year: 2021/2022 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.

Learning outcomes of the course unit
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.
Prerequisites
Practical knowledge of mathematics, physics, thermodynamics, heat transfer and fluid mechanics.
Planned learning activities and teaching methods
The course is taught through lectures and seminars. Lectures are an explanation of basic principles and theory. Seminars (tutorials) are focused on the practical mastery of the subject matter covered in the lectures and include basic design procedures and calculations in indoor environmental engineering.
Assesment methods and criteria linked to learning outcomes
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.
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.
Specification of controlled education, way of implementation and compensation for absences
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).
