Course detail

Energy Simulations

FSI-IESAcad. year: 2019/2020

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).

Learning outcomes of the course unit

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.

Co-requisites

Not applicable.

Planned learning activities and teaching methods

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
