Thermal resistance in some common building elements are indicated in the table below. The values can be used to approximately heat loss calculations from buildings.
|Thermal Resistance Inside and Outside Walls||Resistance (m2K/W)|
|Ri = 1/fi 1)||Ro = 1/fo 1)||Ri+ Ro|
|Building parts against the surrounding environment||0.13||0.04||0.17|
|Building parts others||0.13||0.13||0.26|
|Thermal Resistance for Building Elements against Earth||Resistance (m2K/W)|
|Floors 0.5 m above to 0.5 below earth bound, 0-1 m from inside outside wall - without cold bridge protection||0.2|
|Floors 0.5 m above to 0.5 below earth bound - with cold bridge protection||1.0|
|Center-field above 1 m from inside outside wall||1.5|
|Basement floors 0.5 m below earth bound||2.0|
|Basement walls under earth bound, the whole wall against the earth, where h is the basement floors level below the earth bound (m)||0.2 + 0.3 h|
|Basement walls under earth bound, basement floor against the earth and partly against air||2.0|
- 1 K/W = 0.5275 (h oF)/Btu
