Building Physics 1

Academic Year 2023/24

BHA044 course is part of 1 study plan

BPC-APS Winter Semester 3rd year

Proper design of thermal technical properties of building structures, rooms and buildings ensures the prevention of thermal defects and failures, ensuring the desired state of the internal environment and low energy performance of buildings. In addition thermal microclimate can be optimized design of the structure and the doors and windows to ensure a desired humidity microclimate.

Objective

Construction must be design for and adjudicate so that not happen to rise of the heat technical deficienty or dificiency. Must be fulfil requirements of regulations and from the viewpoint of the thermal cover of buildings and must be securing of low energy costingness of designing building and requisite thermal microclimate.

Knowledge

By attending the course the students will learn the basics of building desing with respect to given standards and regulations, to meet indoor comfort conditions. The will be taught how to assure low-energy demands of a given building by proper thermal desing of the boundary and divisionary construction, and how to eliminate the possibilities of failures and defects.

Syllabus

1. Fundamentals in heat transfer. Thermal comfort in buildings.
2. Steady state heat flux, U-value determination.
3. Temperature profile for steady state conditions.
4. The effect of volume weight and humidity of building materials on the thermal conductivity coefficient.
5. Surface properties, risk of a surface condensation and mould grows, critical surface temperature and humidity, dew point temperature.
6. Thermal properties of windows and doors.
7. Two dimensional temperature profile of characteristic details (critical places in structures - thermal bridges and corners).
8. Assessment and determination of condensation regions into structures, additional protection against vapour and moisture.
9. Annual balance of condensated and evaporated amounts of water in the structure.
10. Non-stationary thermal field, temperature attenuation, phase shift of the temperature oscillation.
11. Floor categories, surface temperature drop.
12. Thermal stability of rooms.
13. Energy efficiency and energy consumption in buildings.
