Home / Concept / Passive house / Superinsulation

Superinsulation 

Superinsulating of the building's envelope means that the elements of this shell should be mainly composed of thermal insulation.

To achieve the requirements of the passive house standard the U-value (thermal conductivity coefficient) should be not greater than 0.15 W/m2K. In Bulgarian climatic conditions, reaching ​​U-values ​​not greater than 0.11 W/m2K could be often achieved.

Scheme of the eligible U-value (thermal conductivity coefficient) of a building's envelope

The U-values ​​of the elements of the building's envelope are balanced to each other and together with all other building components related to its energy consumption should be entered in the overall calculation methodology for the energy model of the building - PHPP.
