Radiation
Posted: Mon Mar 18, 2019 5:47 am -1100
Hello,
I was testing WUFI Plus with some External Climatic Files (we bought to the Portuguese Meteorological entity) and I found that "Global Radiation" does not have an influence on the internal climate simulated (with or without that column, the results of internal climate are the same). On the other hand, "Direct Radiation" and "Diffuse Radiation" plays an important role once the results are much different considering it or not.
So, i would like to understand which Radiation Parameters are the most important, considering i want to simulate the internal climate of my building (and not the component itself), and which Radiation parameters are not that important (Maybe the "Counterrad" radiation for instance, or the "Global Radiation Horizontal" once it has no influence in my test model).
Another question is: if we don't insert any Radiation in the External Climatic File, does Wufi considers any default value? Once in "Location/Climate / Analyse" i can see a "Counterradiation Sum" Value, even when i didnt insert any Radiation Column....
And how it distributes by different orientations?
On WUFI Wiki it refers:
"The radiation rose shows the yearly sum of global radiation for receiving surfaces with different orientations and inclinations"
Does wufi considers any default value and any distribution by Orientation?
Thank you very much in advance.
