Σχετ: [EnergyPlus_Support] Validation -> Zone Mean Air Temperature

[Simeon Oxizidis <simeonagas@xxxxxxxx>]

Hi George,

what type of heating system do you have?

If you have an air system obviously it cannot charge the thermal mass of the building since as soon as the room air temperature reaches the setpoint the system turns off (there is not time to add heat by convection to the buildings elements).

The storage effect can be experienced with a radiation system since in that case first the building elements are being charged (by radiation) and then by convection the room air warms up (which triggers the thermostat operation).

I hope that helps.

Simos

Dear forum

In the framework of a fp7 project, we have to validate the simulation model of a building located at Greece-Chania, to check whether the model leads to the same results as specified in terms of provided measurement data. What seems absurd is that once the heating system turns off a sharp 2 C zone air temperature decrease is occured, which in my opinion means that building does not store heat energy, although the inner layer of the buildings envelop consists of materials with high density. We tried to define an extraterrestrial furniture thermal mass (~35 m^2 - it is not exist in the real building) for each office room and it seems that the simulated temperature curve converges to the measured temperature curve. Any answer would really help.

Thanks in advance,

Giannakis G.
