Second cycle degree in ENERGY ENGINEERING

Campus: PADOVA

Language: English

Teaching period: Second Semester


Number of ECTS credits allocated: 6

Prerequisites: It is not mandatory, but it is recommended to have a basic knowledge on heating and cooling plants and components, i.e. for Italian students "Impianti termici e frigoriferi/Impianti termotecnici".
Examination methods: Students have to deliver one week before the examination a detailed report of their house showing:
- the electric and heating consumptions based on bills
- a thermal bridge of their house: define the heat loss and the possible condensation problem
- determination of the energy demand for heating and domestic hot water, including energy labelling, with a quasi steady state model (EN 13790)
- determination of the net energy demand for heating/cooling the building by means of a commercial dynamic simulation tool (TRNSYS)
- dynamic simulation with cooling plant switched off and evaluation of the indoor temperatures drift
- Comparison between results of calculations and energy bills

The examination will be based on the result of the report (including discussion) and on two questions: one written common question (half an hour) and immediately after an oral question.
Course unit contents: Indoor environmental quality (comfort, ventilation and lighting). Determination of weather conditions for the energy calculation of a building.
Determination of main characteristics and problems related to building envelope: insulation, thermal bridges, condensation.
Determination of main characteristics and problems related to glazing surfaces: lighting transmission, solar energy transmisison, shading, daylighting and glare.
Thermal balance of a room (steady state and dynamic). Determination of heating, domestic hot water, cooling and electrical consumptions of a building.
Energy and environmental certification and labelling.
The concept of multi-energy systems and ZEB (Zero Energy Buildings).
