Passivhaus component certification of the ROI ELIT 93.2 timber window frames, by Grup-35.

CálCalculation and optimisation of the thermal transmittance, Uf, of the frames according to the EN-ISO 10077 1 and UNE-EN-ISO 10077 2 standards, using the finite element simulation program Dartwin Frame Simulator Pro.Through our work, we were able to improve the thermal performance of the frames. We steered the client through the certification process with the Passivhaus Institut, and in under two months, successfully achieved phB class certification for warm-temperate climates.

Hormipresa Arctic Wall Passivhaus Component certification

R&D

Description

Passivhaus Component certification of the Hormipresa Arctic Wall construction system: a fully industrialized, high thermal inertia solution with an exterior white concrete finish. It has been certified as a Passivhaus component for the warm-temperate climate zone.

To reach the Passivhaus Component certification Praxis undertook three-dimensional simulations of the wall to determine the thermal effect of the steel connections penetrating the insulation layer using Dartwim Mold Pro 3D and Flixo Pro finite element simulation packages.

We calculated and optimised 10 standardised construction details, as required by the certification, associated with wall, roof, and floor connection details, and window installations. Praxis managed the certification process with the Passivhaus Institut.

The certification criteria for warm-temperate climate requires a U_wall ≤ 0.25 W/m2·K and all construction details must be thermal bridge free with Ψ ≤ 0.01 W/m·K.
