U-value from Delphin
Verfasst: 25 Mär 2021, 16:24
Dear Delphin Team,
I would like to evaluate the effective U-value of a wall from my Delphin simulation.
1. Is there a direct output of the U-value in Delphin?
2. If the U-value cannot be directly exported from Delphin, then I assume that it should be calculated from the temperature difference and heat flux. If this is the case, is there a certain recommendation for the threshold of the temperature difference for the U calculation? (Naturally, simulation results in the days with small indoor/outdoor temperature difference cannot be used for such calculation).
3. Is there a recommendation on how to average the transient hourly calculated U-values into a single U-value? This would depend on how the thermal mass is considered in Delphin.
Thank you very much for your help.
