Year	2
Semester	S1
ECTS Credits	6
Workload	PL(30H)/T(30H)
Scientific area	Construction
Entry requirements	Knowledge of Building Physics.
Learning outcomes	The curricular unit of Energy Efficiency in Buildings aims to provide theoretical and practical knowledge concerning the implementation and evaluation of energy efficiency improvement solutions in buildings. The following competencies will be developed in this curricular unit: a) Ability on the methodology of evaluation of the energy performance of residential buildings. b) Ability on current legislation to evaluate the energy performance of residential buildings. c) Ability on building thermal design and determination of energetic classification and CO2 emission. d) Ability to identify the processes and measures to improve energy efficiency of buildings, to identify the requisites of the nearly zero energy buildings (NZEB) and to understand the concept of passive house. e) Ability on assessment of the economic impact of the implementation of energy efficiency improvement solutions.
Syllabus	1) Framework of energy policies related to energy efficiency in buildings; 2) Heat transfer by transmission in the building envelope elements (opaque and glazed); Heat transfer associated with air renewal; Solar gains and internal gains; Thermal inertia and useful heat gains; Energy balance in heating and cooling seasons; 3) Active technical systems for heating, cooling and preparation of sanitary heat water; Renewable energy systems; Passive systems for heating and cooling; Energy needed for the preparation of sanitary heat water; Primary energy; CO2 emissions and Energetic Class. 4) Processes and measures to improve energy efficiency in buildings, requirements for nearly zero energy buildings (NZEB) and the concept of passive house. 5) Calculation of energy bill, increased investment costs, energy savings and simple investment return period.
