FISICA TECNICA INDUSTRIALE E AMBIENTALE
Module FISICA TECNICA AMBIENTALE

Academic Year 2024/2025 - Teacher: GIANPIERO EVOLA

Expected Learning Outcomes

Modulo "Environmental Physics"

The course provides students with the ability to evaluate the parameters that determine the quality of work environments, and any health risks, in the field of thermal comfort, air quality, acoustics and vision. Students will learn to measure these parameters, compare them with any optimal or regulatory values, and then establish and implement - together with a technician - the most appropriate mitigation strategies.

Course Structure

The contents of the discipline will be discussed through traditional lectures.

Required Prerequisites

Basic knowledge in Physics and Mathematics

Attendance of Lessons

Attending the lectures is COMPULSORY, with a minimum attendance rate complying with the requirements set by the University.

Detailed Course Content

THERMAL COMFORT and AIR QUALITY (14 hours)

- The energy balance of the human body

- Indicators: PMV and PPD (moderate environments), WBGT and WIND CHILL (severe cold environments)

- Measurement of environmental parameters (air temperature, relative humidity, air velocity)

- Practical examples of assessment and case studies

- Indoor pollutants and their effects on health

- Measurement of the concentration of pollutants

- Ventilation requirements for the healthiness of the environments, and related regulatory references

- Case studies: measurement of CO2 and CO concentration in school and work environments


ACOUSTICS AND NOISE RATING (14 hours)

Main definitions (frequencies, levels, dB) 

Basic operations: sums and subtractions of levels

- Physiology of the human ear

- A-weighting and normal audiogram

- Concept of equivalent level and differential level

- Effects of noise on humans

- Acoustics in workplaces: Decree 81/08

- Admissible limits and use of PPE

- Measurements: the sound level meter and related processing software

- Noise mitigation strategies in workplaces

- Examples and case studies

 

LIGHTING TECHNOLOGY (7 hours)

- The light and physiology of the human eye

- Main definitions (luminous flux, illuminance)

- Types of lighting fixtures and their characteristics

- Criteria for assessing the suitability of light in the workplace

- On-site measurements and verification example

- Strategies for improving lighting in workplaces

"Contribution of the Course to the objectives of Agenda 2030 for Sustainable Development
The course contributes to raising awareness and training students on the issues and technologies that underpin Goal 3 (Health and wellness), Goal 8 (Decent work and economic growth) and Goal 12 (Responsible consumption and production).
