Tallinn university of technology CFD study

How do heat and air behave in building insulation? The nZEB research group used greenteg’s heat flux sensors in their 3D computational fluid dynamics study.


The nZEB research group at Tallinn University of Technology, led by Jaanus Hallik, used a steady-state 3D computational fluid dynamics (CFD) method in this study.

Using a parametric method, the heat transfer coefficients were evaluated inside the building envelope’s 20-cm thick insulation layer with partially and fully permeable air cavities. The greenteg gSKIN® heat flux measurement sensors were an important part of the validation process.


The gSKINgt is a sensor for measuring heat flux in building envelopes, building components and building fabric.
