Specific course objectives

The course is aimed at engineering students to improve their knowledge about noise pollution, its reduction in urban areas, and about global environmental confort outdoors. The control of air pollutant emissions, particularly CO2, may be performed at the source, by reducing energy consumption in buildings. Air conditioning systems in buildings, and use of solar energy to reduce heating loads in buildings are analysed. The student will have the basis knowledge about analysis of the feasibility of reducing consumption of HVAC Systems and the use of solar collectors. The course of Hydraulic Machines aims to show the characteristics and basic operating principles of hydraulic machines commonly used in industries. Particular attention is focused on the choice of the most appropriate machinery and on flow rate regulation system in order to maximize plant efficiency.

Course programme

Noise Pollution
Noise propagation principles. Sound absorption, materials, noise reduction by means of barriers. Outdoor environment: noise sources in urban areas, classification of noise, noise measurements and evaluation criteria, analysis of actions to reduce noise. Plans to safeguard environmental quality, environmental protection against noise. Analysis of geomorphological, meteorological, anthropological and settlement characteristics of the territory. Noise sources and mapping in terms of noise pollution. Methods of intervention for the noise reduction in highly polluted areas.

Energy performance of buildings
Methods for evaluation of energy performance. Energy balance and international-national standards. Energy-saving technologies. System types existing and innovative solutions. Efficiency of heating and air conditioning systems. Solutions for the building envelope and systems to reduce energy consumption in buildings.

Solar energy
Energy saving is also based on better exploitation of natural resources. The use of solar water heaters offers good ideas for reducing fuel consumption and pollutants into the atmosphere. Evaluation of the solar energy that can be used. Common types and innovative solar panels. Hydraulic system and possibility of use as hot water and support heating systems. Analysis of achievable energy savings . Calculation methods of the benefits of collectors and water heating solar systems. Installation design.

Hydraulic systems
General principles Thermodynamic and fluid-dynamic principles of fluid-operating machines. Mass and energy conservation. Relative motions, Euler equation.-------------- Pumps Classification and selection criteria. Operating parameters: head, efficiencies and power required. Performance curves, design and off-design operating conditions: flow rate control methods. Cavitation, NPSH required. Affinity laws for turbomachines.

Testing and exams

The final verification is represented by a written test and an oral exam (usually the day after the written test) in the dates fixed in the calendar. It is possible to carry an exercise (optional) on the application of concepts. The mode of execution and delivery of the exercise, the access to educational materials are given in the teacher's web page.
