Prerequisites
Basic knowledge of Mathemathics and Physics.

Learning outcomes
The aim of the course is to specify the basic notions of applied thermodynamics, thermal transfer, applied acoustics and lighting technique.

Program
Introduction to thermodynamics. Basics of thermometry. State thermodynamics. Thermodynamics Charts. Vapours, ideal gas, incompressible substances. First law of thermodynamics for closed and open systems. Application of first law to simple system components. Second law of thermodynamics. Clausius and Kelvin postulates. Direct and reverse thermodynamic cycles. Direct and reverse Carnot cycle. Entropy. Vapour compression reverse thermodynamic cycle. Heat transfer mechanisms. Steady state conduction. Electric analgy and resistive model. Thermal convection. Flow regimes. Adimensional numbers and correlations for practical use. Thermal radiation. Black-body and real-surfaces radiation. Heat transfer between black bodies, gray bodies within cavities. Heat transfer combined mechanisms. Walls transmittance. Enhanced heat transfer. Thermodynamic properties of gas-vapor mixtures. General definitions. The psychrometric charts. Human thermal comfort. Fanger equation. Comfort parameters. Building thermophysics. Heat and mass balances. Acoustic comfort. Fundamentals of sound waves. Phono adsorbance. Phono insulation. Visual comfort. Photometric parameters. Indoor lighting computational methods.

Development of the examination
LEARNING EVALUATION METHODS
The assessment of student learning consists of two parts: - A written test, consisting in the solution of two or three exercises on topics covered in the course, to be completed in two or three hours, depending on the type of exercise; - An oral, consisting in the discussion on one or more topics covered in the course. To access the oral exam, the student must have obtained at least a pass in the written test. In case of failure of the oral exam, the student must also repeat the written test.

LEARNING EVALUATION CRITERIA
To successfully pass the exam, the student must demonstrate, through the tests described above, to have understood the concepts of applied thermodynamics and heat transfer exposed during the course.

LEARNING MEASUREMENT CRITERIA
For each one of the tests specified before, it is assigned a score between zero and thirty. The overall grade, thirty, is the average of the marks obtained in the two tests, with rounding to the entire excess.

FINAL MARK ALLOCATION CRITERIA
Because the overall outcome of the evaluation is positive, the student must achieve at least eighteen points in each of the tests described above. The highest rating is achieved by demonstrating a thorough understanding of the course content in the tests.
