What is a building envelope?
The Building Envelope and heat flow
Conduction – In this way, heat will transfer directly from one part of the object to another part by the molecules bumping into each other. Some materials conduct heat better than others, depending on its structure. Insulation is structured in a way that it reduces heat flow with tiny air pockets that are relatively poor conductors of heat.
Convection – Fluid or even just movement of air can transfer heat by the convection method. In an uninsulated wall space air will pick up the heat from the warm side of the wall and then transfers it to the cold wall where it will lose the heat.
Radiation – Any object can radiate heat in the same way a fire radiates heat. When you are standing in front of a window you will radiate some heat to the window hence, you will feel cold even though the temperature in the room is warm.
