Energy Management

Recommended Prerequisites

Termodynamics and physics (elctricital current).

Teaching Methods

The teaching methodology involves lectures for the presentation and development of concepts and/or tools, using slides and, often, the illustration with real situations; Exercise classes for the practice of application of concepts and tools to concrete situations. The teaching methodology involves also a significant tutorial support during the conducting of a group work energy analysis and optimization of an industrial process.     

Learning Outcomes

The purpose of the Energy Management curricular unit is to provide the students with a set of knowledge and tools to allow them to realize the economic and environmental importance of the rational use of energy and to enable the analysis and optimization of the energy production or consuming systems.

LO1 Provide students contact and familiarity with the mandatory aspects, rules and directives applicable in the context of energy management and energy efficiency;

LO2 Promoting the ability to develop, determine and analyze energy performance indicators;

LO3 Develop the ability to evaluate in detail, by performing mass and energy balances with chemical reaction, for example, the operating conditions of the main energy consumers in a particular installation;

LO4 Develop the ability to propose measures to improve energy efficiency;

LO5 Provide students familiarity with the concept of exergy and promote its use in the analysis of the energy performance of complex systems.
