PROGETTO DELLA QUALITA' ENERGETICA DEGLI EDIFICI E DEGLI IMPIANTI

Learning Objectives

• QUALITA' ENERGETICA DEGLI EDIFICI E DEGLI IMPIANTI

  The course aims at providing the students with the technical and scientifc bases needed to evaluate the energy performance of buildings and their technical systems, and to perform the sizing and the preliminary design of the different components (e.g. radiators, distribution networks, heat generators and security components).

  To this aim, the course will show the most recent technologies for the energy efficiency of buildings and technical systems, and the corresponding sizing approach. The course will also deal with passive and active strategies for space heating and cooling, including solar thermal and photovoltaic systems. Indoor air quality and thermal comfort will also be thoroughly discussed. These background will allow the students to address the energy certification of buildings and their dynamic energy simulation, in order to verify the compliance with the most recent and strict regulations.

Course Structure

• QUALITA' ENERGETICA DEGLI EDIFICI E DEGLI IMPIANTI

  All course contents will be presented through traditional lectures.

• Dynamic energy simulations - Energy Certification

  A first assisted exercise will deal with the dynamic energy simulation of buildings. The students (organized in groups of two people) will perform the dynamic energy simulation of a residential building, in order to assess the energy needs for space heating and cooling, as well as the indoor thermal comfort conditions. After evaluating the performance of the building in its current configuration, the students will propose and discuss suitable renovation strategies. The results will be commented in a final report.

  A second assisted exercise will deal with Energy Certification and the sizing of the heating systems. The students will generate the Energy Performance Certificate for the same residential building already considered during the first period, and will perform the sizing of the main components of the heating system.
