The envelope (enclosure) of the building consists of roofs, walls and windows. The U-value (W/m2.K) of envelope means, the heat transmission through materials of walls and roofs. The lower U-value, the higher thermal resistance.
For example: The area of the wall shown below is 3.0m X 6.0m= 18.0 m2
The area of the window is 2.0m X 0.5m= 1.0 m2
So, the window/wall ratio is = [ Area of the window(s) / Area of the wall ] X 100 = 1/18 X 100 = 5.56%
