To calculate the u-value of the building element, the r-value of all the different components that make up that element will be considered. U-value (of building element) = 1 / (rso + rsi + r1 + r2 …) where rso is the fixed external resistance, rsi is the fixed internal resistance and r1, r2 etc.
How to Calculate U Value?
Calculating U Value is an important part of energy conservation. U Value is a measure of thermal resistance or a measure of the rate at which energy is transferred through a material.
The U Value measures the amount of energy that is lost through a structure, such as a wall or roof, when the temperature difference between the inside and outside is one degree Celsius.
U Value is used in both residential and commercial buildings to ensure that energy is conserved and that the building is as energy efficient as possible.
The most important factor when calculating U Value is the thickness of the material used in the construction of the building. The thicker the material, the less energy that is lost through it.
This is because thick materials have a greater insulation capacity and therefore are better able to keep the temperature of the building stable.
It is also important to consider the type of material used in the construction of the building, as some materials have a higher U Value than others.
Another important factor when calculating U Value is the type of glazing that is used in the windows and doors of the building.
The type of glazing used will affect how much energy is lost through the window or door and so this needs to be taken into account when calculating U Value. When calculating
