1) Deduce the general energy balance equation for a humid environment (in terms of operating temperature of the internal environment) starting from the integral balance equations of mass and internal energy, explaining the meaning of the terms that appear therein; define the sensible and latent heat load and then derive from the energy balance the equation for calculating the sensible heat load in summer (give its definition!), explaining any approximations introduced. 2) Air infiltration through the build ing envelope: define the types of infiltration (cause -effect relationship), the calculation models and the parameters used. 3) Explain what Sustainability means and what is the Building Sustainability Assessment according to EN and ISO standards. 3) What does Indoor Environmental quality means and what could be the best way to asses it. 3) Thermal Comfort: explain the heat balance of the human body, describe the PMV and PPD criteria (definitions and parameters for calculation), and other experimental indices. 3) Indoor Air Quality: explain the air contaminants mass balance equation and the difference between the ventilation effectiveness and the ventilation contaminant removal effectiveness. Explain how to perform an IAQ design using a prescriptive approach. 3) Acoustic Comfort: explain the difference between Acoustic Quality and Acoustic Comfort; explain how we account for human perception in assessing the Acoustic Comfort; explain what is/are the indicators used to assess the acoustic comfort. 3) Visual Comfort: how we account for human perception in assessing the Visual Comfort and what are the main factors influencing it; explain what is/are the indicators used to assess the visual comfort. 3) Explain the definition of a Nearly Zero Energy Building and what…
