Knowledge and application of energy performance assessment methodologies for the existing buildings. Learning of the calculation methods to forecast the building energy demand for the different energy services (i.e. space heating, space cooling, ventilation, domestic hot water production, lighting, lifts and escalators). Analysis and processing of real energy consumption data of buildings. Technical and economic evaluation of energy retrofit actions. Ability to draw up an energy audit report and an energy performance certificate.

Fundamentals of building energy balance, room moisture balance and energy need calculations. Concepts of thermal comfort and indoor air quality, indoor monitoring and measurement of thermo-physical quantities. Basic knowledge of building energy regulations.

Classification of building categories and of energy services: space heating and space cooling, air conditioning, mechanical ventilation, domestic how water production, lighting, lifts and escalators. Summary on indoor thermal comfort and user characterisation: thermo-hygrometric parameters of thermal comfort and indoor air quality, user models and occupant behaviour assessment. Overall energy performance of buildings. Classification and characterisation of technical building systems and thermal subsystems (heat generation, storage, distribution, control and emission). European and Italian regulations framework on the energy efficiency in buildings: Directive 2010/31/EU (EPBD recast) on the building energy efficiency, Directive 2012/27/EU on the energy efficiency, Directive 2009/28/EU on renewable energy sources, Italian Legislative Decree no. 192/2005 and subsequent amendments, Italian Ministerial Decree 26/06/2015, Italian Legislative Decree no. 102/2014 and subsequent amendments, Italian Legislative Decree no. 28/2011. Deepening of the building energy performance assessment according to international technical standards: holistic approach and types of energy assessments (EN ISO 52000-1), indoor environmental quality assessment (EN 16798-1 and ISO 17772-1), building energy needs (EN ISO 52016-1), thermal losses and efficiencies of technical building systems (EN 15316, EN 16798), energy demands for lighting (EN 15193). Specifically, the following arguments will be analysed: building energy balance in dynamic and quasi-steady-state conditions, calculation of thermal systems losses, of delivered energy and of primary energy use, taking into account the primary energy conversion factors of different energy carriers. Data collection and in field measurements, and data cataloguing. Use of data driven inverse models and calibration procedures according to technical standards (ASHRAE Guideline 14-2014). Presentation of energy efficiency measures and technologies for building refurbishment. Technical and economic analysis of investments for energy renovation (EN 15459). Building energy certification. Basic notions of environmental certification.

Teaching is organised both in theoretical and application lectures, and in exercises. The exercises will cover applications of some aspects of energy and economic assessment. In addition, the students will develop a design exercise consisting in a detailed energy audit of a large building.

EXAM DESCRIPTION The exam consists of two parts, both compulsory: a written test and an oral interview. The written test is structured in two parts: • a theory test, with both closed and open answers (duration 45 minutes), aimed at verifying the acquisition of theoretical concepts, and • a numerical exercise (duration 1 hour), aimed at verifying the ability to apply theoretical concepts. The theory test consists of 20 true-or-false statements and 3 synthetic definitions or concepts to be explained. The oral interview is aimed at verifying the design skills. It consists of the presentation and critical discussion of the final product of a design exercise; the student will have to justify the design choices and calculation results on the basis of the knowledge acquired in the theoretical lectures. Questions and insights on the theory are possible during the oral interview. EXAM PROCEDURE The theory test with closed and open answers will be carried out onsite. The numerical exercise will be carried out onsite. The numerical exercise will start immediately after the end of the theory test for the onsite exam. The oral interview will be carried out onsite. The oral interview will be scheduled within one week of the written test. EXAM RULES The written test and oral interview must be taken in the same session. If one fails the oral interview, also the written test must be repeated. The exam booking on the didactics portal is mandatory. During the theory test the student is not allowed to use any support (book, note, lecture notes, slide, technical standards, others). During the numerical exercise the student is allowed to consult: technical standards (the own student copy), books, notes, lecture notes, slides. Texts containing exercises are not allowed. GRADING The score of the written test is in thirtieths, with the following weights: 25% for the true-or-false statements, 25% for the synthetic definitions, and 50% for the numerical exercise. The maximum score of the written test is 32/30. The threshold for accessing to the oral examination is 15/30. The grade of the oral interview depends both on the quality of the design exercise and on the assessment of the interview. The final grade of the exam, in thirtieths, is the arithmetic mean of the written test and of the oral interview (with a minimum grade of 15/30 for each of the two parts).

In addition to the message sent by the online system, students with disabilities or Specific Learning Disorders (SLD) are invited to directly inform the professor in charge of the course about the special arrangements for the exam that have been agreed with the Special Needs Unit. The professor has to be informed at least one week before the beginning of the examination session in order to provide students with the most suitable arrangements for each specific type of exam.
