Hi I am trying to find the right output variable to calculate the energy balance for a building with idea loads system.
as I have understand until now the following variables is the soloution to this answer
1. Zone Air Balance Internal Convective Gains Rate --> Heat gains from Internal gains to the zone node air
2. Zone Air Balance Surface Convection Rate --> Heat from all surfaces to the zone air node
3. Zone Air Balance Interzone Air Transfer Rate --> infiltrarion / ventilation heat to the zone air node
4. Zone Air Balance System Air Transfer Rate --> hvac system supplementary heat
5. Zone Air Balance Air Energy Storage Rate --> heat storage in air
6. Zone Air Balance Deviation Rate --> imbalance, in watts, in the energy balance for zone air
The part that I cannot resolve is the solar energy that comes into zone due to windows. One question that i have is bout the variable Zone Air Balance Internal Convective Gains Rate. Does this include the transmitted solar energy or I should add the variable Zone Transmitted Solar.
also I would like to ask about the Interzonal heat transfer from zone to zone. is there any variable that can give this heat transfer for each zone or the only way is to sum the heat transfer of each individual internal wall ?
thank you in advanced
