Recommended Prerequisites

Buildings and Environment, Building Envelope - Outside Environment, Indoor Environmental Quality.

Teaching Methods

Oral lectures with audiovisual resources to explain theoretical concepts and solving practical illustrative problems. Lectures for use of simulation tools, solving practical examples. Tutorial support for individual practical work where the students must use simulation tools to analyze the energy performance of buildings, with auxiliary HVAC systems.

Learning Outcomes

The Programs for Building Energy Simulation (BES) reached a state of maturity and reliability that allow to be fundamental tools to help in the efficient energy design of buildings, including the study of the energy performance of architectural solutions, building elements and HVAC systems. Thus, the objective of the course is to teach the main theoretical issues related to the BES calculations, but also give to the students the procedures and practices of good and effective use of BES programs. In this second perspective the students will acquire skills to apply the general criteria for the definition and parameterization of buildings models and perform a critical analysis of the results.
