D2-U-value estimations based on measured temperatures - internal surface heat transfer
The theory of 1D steady state heat transfer learns that the thermal transmittance U of a wall with parallel layers easily can be derived from the environmental temperatures θi and θe, the internal surface temperature θis and the internal surface heat transfer coefficient hi.
This would in theory allow to estimate the U-value of 1D-building components based on IR-thermography measurements.
In a case study a temperature distribution in steady state conditions for a well-defined building zone is generated numerically. The detailed numerical heat transfer simulation, based on 3D conduction, view factor based radiation (radiosity method) and empirical convection, guarantees a quite realistic temperature distribution.

Visual validation of 3D heat transfer
At first sight a visual validation of heat transfer seems to be a contradiction: only the infrared radiation and not the visual light emitted by surfaces is related to the temperature. However, as surface condensation is visual and depends on the surface temperature, a visual validation of heat transfer is possible by comparing the pattern of drying surface condensation to the simulated isotherms on the surface.

Dealing with thin metallic layers in the program BISCO
The heat transfer through thin metallic layers can be simulated using the Physibel programs TRISCO and BISCO. Whereas thin layers are possible in TRISCO (through thin grid widths), the lowest layer thickness in BISCO is limited to the pixel size. A very small pixel size sometimes results in a too large bitmap due to a memory problem. An alternative approach for such cases is proposed. The method is validated for a plastic glazing spacer covered with a metallic layer.

C10-Thermal simulation of vacuum glazing
Creating a vacuum layer between 2 glazing panes, of which one has a low emissivity coating, results theoretically in a glazing with a very low thermal transmittance, due to a very low heat transfer by conduction and radiation over the cavity. However, practically border and punctual spacers are required to maintain the vacuum. These spacers cause an additional 3D conduction heat transfer effect, increasing the thermal transmittance. The vacuum glazing is simulated in 3D using the program TRISCO with the RADCON module.
