Topic 1: Fundamentals of building physics
In this part of the course, fundamentals of conductive, convective and radiative heat transfer are reviewed, and these concepts are next employed in the context of building physics. Next, the characteristics of solar radiation are explained, providing the student with the possibility of calculating the available irradiation at a specific location, wall direction and time. The concept of thermal comfort is next presented in detail, which enables the students to understand the reason behind the standard choices of desired internal condition in both heating and cooling cases. In the next step, psychrometric fundamentals and the governing equations of humid air are reviewed and the students will learn how to use the psychrometric chart in order to calculate the heat and moisture transfer in airconditioning processes.
The students will then learn about the standard simplifications for calculating the heat transfer through the walls and windows and how to use the corresponding tables. The underlying physical phenomena behind the internal heat gains and infiltration are then presented and the standard methods for determining the corresponding values in buildings are introduced.
Finally, employing the previously presented concepts, the commonly used ASHRAE methods, for calculating the heating and cooling loads in residential buildings (RLF method) and nonresidential dwellings (heat balance method) are presented.
Accordingly, the first part of the course is made up of the following subtopics:
1.1 Review of conductive and convective heat transfer
1.2. Review of radiation heat transfer
1.3. Solar radiation
1.4. Heat transfer through walls and windows: simplifications
1.5. Heat Transfer through the ground and basement along with the thermal bridges (not included in the student evaluation)
1.6. Thermal Comfort
1.7. Psychrometric fundamentals
1.8. Heat gains and infiltration
1.9. Residential heating and cooling load calculation, ASHRAE RLF method

*Simulation Tools:
Python programming language is employed for conducting the abovementioned calculations in an automatic manner. After utilizing python for carrying out single objective tasks, the students will use this tool to implement the whole calculation procedure of the RLF method. GIT version control system and GitHub are utilized for sharing the corresponding codes.
OpenStudio (an EnergyPlus based tool) is also introduced and is then utilized for carrying out the heat balance method in order to calculate the heating and cooling load of commercial buildings.
