Hello everyone,
As I am conducting thermal simulation in a high glazed zone (conservatory), I am concerned about thermal mass of glazings. According to the documentation, thermal mass is set as null for glazings.
But, after a hard work of fitting between my simulation model and some experimental data, I noticed that my simulation model is “lighter” than the experimental one (air temperature variates more reactively in simulation).
So, I calculated the thermal mass of all inner glazings (well I approximated it) and added the result to the zone capacitance. The result is very encouraging and I’m quite happy with the simulation model as it is set now. However, I would
like to have your feedback on this. What would be your judgment on this method as thermal experts and is there another way to add a thermal mass to the glazings ?
Best regards
