What describes Building physics?
It describes the basics about energy flows in buildings.
List 5 influences on a building
Sun, Wind, Noise, Snow, Rain, Hunidity, Lightning, Earthquakes, Plants, Animals
Describe the ideal building design.
It would create the desired internal room conditions without additiona technical equipment or generating an enrgy demand.
List the two kinds of heat loss:
Heat loss by transmission
Ventilation heat loss
How works the first kind of heat loss?
Heat is transmitted through walls (and windows,doors,roofs) if there is a temperature gradient between the inside and the outside of a building. The magnitude of the heat transmitted is proportional to the thermal insulation (heat transfer coefficient U), to the area of the structure, and to the temperature difference.
Which is the most important part of a building to insulate?
The roof, the warm air rises beneath it and gets stucked there. If the warmth just gets lost there it never gets warmer at the bottom.
Why is there nearly no transmitted heat flux from the outside to the inside even if the outside temp exceeds the inside temp?
This is because most of the time the daly mean temp outside is lower than inside. During the day, the outer wall becomes heated up and during the night the direction of the heat flux changes and the heat stored is emitted to the exterior.
When effects the heated up wall the interior temp?
If its a lightweight wall or roof.
