Educational objectives | The Environmental Applied Physics module has the main objective of providing students with fundamental knowledge on environmental comfort and impacts due to different types of polluting sources (odors, noise, light radiation). In addition, students are provided with the fundamental notions of thermodynamics, the basic concepts of heat transfer and the air treatments that characterize air conditioning plants. The main knowledge acquired will be: 1. the methods of heat transfer and their characteristics. 2. The main configurations of air conditioning plants and the air treatments that characterize them 3. Methods and parameters for evaluating thermohygrometric comfort. 4. Methods of assessing the odor impact. 5. the main acoustic parameters and the evaluation indexes of the noise disturbance 6. The parameters for evaluating light comfort. The main skills (i.e. the ability to apply the acquired knowledge) will be: 1. to be able to identify thermohygrometric comfort problems in closed and open environments. 2. how to identify problems of environmental pollution in the workplace. 3. how to estimate the effects of noise sources in closed and open environments. 4. how to identify problems of light comfort. |
Prerequisites | No specific prerequisites. |
Teaching methods | Methods of teaching Lesson hours: 20 Supports for Teaching and Learning - Video projections of the lessons - Educational materials distributed by the teacher - Recommended texts for the study - Handouts available on web site Learning mode (in addition to the attendance of teaching activities) - Reading and personal study on material given by the teacher - Reading and personal study on online material made available by the teacher - Reading and personal study on reference books |

Learning verification modality | The exam consists of a written test, with an open question and a series of multiple choice questions. The questions will focus on the topics covered during the lessons. The open question can be replaced by the writing of an in-depth text on a topic covered by the lessons. |
