The lowest outdoor air temperature used in the calculations, ie the lowest outdoor temperature that the indoor temperature should be maintained.
The temperature to be kept inside the room in question.
The lowest temperature in the ground to be used to calculate the transmission loss to the ground.
Refers to the temperature of the air that is blown into the room through the ventilation.
Specific heat capacity or cp is a measure of a material's ability to store thermal energy. If the unit for the specific heating capacity is J/(kg*K).
The density of the air that enters the room in question. Density or volume mass is a SI unit and is a measure of the density of a specific substance, ie mass per unit volume. A synonym for density that can sometimes occur is specific weight.
| Exterior wall | A wall that limits the room to the outdoor air. |
| Basement wall | A wall that confines the room to the ground. |
| Window | A window that limits the room to the outdoor air. |
| Door | A door / door that limits the space to the outdoor air. |
| Ceiling | A building part that limits the space to the outdoor air. |
| Floor (0-1) | A floor that limits the space to the ground and is between 0 and 1m from the facade. |
| Floor (1-6) | A floor that limits the space to the ground and is between 1 and 6m from the facade. |
| Floor (>6) | A floor that limits the space to the ground and is more than 6m from the facade. |
Refers to the area of the building part to be calculated.
An area that is removed from the area specified under "Area" this to facilitate the measurement of the area such as reducing the wall area with the area for windows and / or doors.
Is the area on which the calculations are made.
The difference in temperature between the different sides of the building part in question.
A value that shows how much heat goes through the wall, the higher the value the worse the insulation part insulates.
A measure of how dense the current building part is.
The power needed to compensate for the transmission losses.
The amount of air that enters the room through the ventilation.
