In most of the building structures rock wool KnaufInsulation DP-8 fibrous insulation in the form of boards with size of 120 x 60 cm is placed. Part of the wall in the bathroom is thermally insulated with flock insulation KnaufInsulation SUPAFIL, which was blown into wall cavity. In some structures are used, due to the smaller thickness, in addition to rock wool, insulation with foil CMC Ekocon TRISO-SUPER and vacuum panels of company TURNA Turvac. The measurement results of U values of these structures can be found in chapter: >monitoring >report. As part of the façade system JUBIZOL a layer of expanded polystyrene with added graphite with thickness of 2 cm and layer of expanded polystyrene on the inner side as part of the heating system TITAN Uponor is built.

     

Thermal transmittance was calculated using the software KI ENERGIJA 2010. The majority of building construction has a U value that is 50% less than allowed (Uwall 0.28 W/m²K, Uroof 0.20 W/m²K), the average thermal transmittance of the Cell envelope meets the requirements of passive buildings.

Thermal bridges in building constructions were evaluated with the software PHYSIBEL. Linear thermal transmittance of most thermal bridges has a value of less than 0.01 W/mK, so they do not affect the heat transfer. The only exception are the thermal bridges at windows, which at the appropriate temperature factor, due to the small length practically do not affect the thermal properties of the Cell envelope.
