Building Energy Performance Calculation
General details of the subject
- Face-to-face degree course
Description and contextualization of the subjectThe subject of "Building Energy Performance Calculation", taught in the Erasmus Mundus Master in Smarts Cities and Communities (SMACCs), is a compulsory subject of 6 ECTS that is part of the major Energy Efficiency in Buildings.
The final objective of this course is to put into practice the fundamental and advanced concepts of buildings physics through the use of tools for estimating the energy demand of buildings, as well as their energy consumption through the analysis of different types of thermal systems. By means of these tools it will be possible to evaluate the energy performance and energy efficiency of buildings, quantifying the impact that different actions (active or passive) may have on residential or office buildings, as well as the use of different thermal systems (boilers, heat pumps, thermal panels, etc.).
Generally, this type of building energy simulation tools are used for thermal systems design and to evaluate the economic/environmental costs or energy benefits of different strategies, both in the building design stage and for decision making in retrofitting.

TemaryThis course is focused on the acquisition of fundamental and advanced concepts in the field of energy in buildings. The variables and parameters influencing the thermal behaviour of buildings and HVAC systems will be analysed and evaluated from a theoretical and practical point of view through their implementation in a building energy simulation tool. In addition to this, guidelines will be given on the possible modifications to be made in buildings to improve their energy efficiency. For this purpose, Design Builder software will be used as a computer calculation tool.
