Energy Simulations (FSI-IES)

Academic year 2018/2019
Supervisor: prof. Ing. Miroslav Jícha, CSc.  
Supervising institute: EÚ all courses guaranted by this institute
Teaching language: Czech
Aims of the course unit:
The main goal of the course is to make students familiar with capabilities and limitations of energy performance simulation tools for buildings and building equipment. During tutorials students will acquire basic skills in the practical use of the simulation software TRNSYS-TRNFlow.
Learning outcomes and competences:
Students are made familiar with capabilities and limitations of energy performance simulation tools for buildings and building equipment. They will also acquire basic skills in practical use of energy simulation tools.
Prerequisites:
Students should have fair knowledge of energy performance of buildings and building equipment (heating, ventilating and air-conditioning). They should be familiar with numerical methods and they are expected to have basic computer skills.
Course contents:
The course is aimed at the computational energy simulations. Energy simulations provide more detailed information about the performance of buildings and building equipment than steady-state calculation techniques. The input parameters of energy simulations (outdoor temperature, solar radiation intensity, occupancy, air change, etc.) vary significantly during a day and throughout a year. The energy simulations allow to change input parameters in each time step, which is usually 1 hour, and thus to model reality quite accurately. The importance of energy simulations in building design in the EU countries increases with the progress of implementation of the EPBD (Energy Performance of Building Directive).
Teaching methods and criteria:
The course is taught through lectures explaining the basic principles and theory of the discipline. Exercises are focused on practical topics presented in lectures.
Assesment methods and criteria linked to learning outcomes:
The graded course-unit credit requirements: 20% continuous assessment (activity during tutorials) 80% completion of a project assigned by the tutor
Controlled participation in lessons:
The students are obliged to attend seminars and complete a project assigned by the tutor.
Type of course unit:
    Lecture  13 × 1 hrs. optionally                  
    Computer-assisted exercise  13 × 1 hrs. compulsory
