Recommended Prerequisites

Buildings and Environment

Teaching Methods

Lessons for the presentation of the fundamental physical concepts and resolution of simple illustrative examples.

Lessons where practical problems are presented, discussed and solved.

Elaboration by the students of a report about specific topics within the HVAC and building systems scope, focused on the best available techniques.

Learning Outcomes

The main scope of this course is to present and develop the fundamental concepts about heating, ventilating and air conditioning of buildings and related systems. The topics related with health and thermal comfort, building thermal behavior and loads, psichrometric processes, ventilation principles and the HVAC components and systems, will give the students the necessary background to proceed in the design, analysis and operation of HVAC systems.
