The columns are:
Calculation time - this will show the time steps used by the simulation and by the sizing calculation.
Sizing Calculation Fields[LINK]
Each of the Zone Sizing output fields has the Zone Name, the Environment Name for the peak prepended to the item that has been calculated. The four fields calculated are:
- Des Heat Load
- Des Sens Cool Load
- Des Heat Mass Flow
- Des Cool Mass Flow
These are repeated for the number of zones in the sizing calculation.
Field: Des Heat Load [W][LINK]
This is the calculated design/required heating load at the time step.
Field: Des Sens Cool Load [W][LINK]
This is the calculated design/required cooling load at the time step.
Field: Des Heat Mass Flow [kg/s][LINK]
This is the calculated design/required heating mass flow rate at the time step.
Field: Des Cool Mass Flow [kg/s][LINK]
This is the calculated design/required cooling mass flow rate at the time step.
This indicates the peak calculation (load or mass flow) over the 24 hour condensed sizing period.
Line: Peak Vol Flow [m3/s][LINK]
For the mass flow rates, this indicates the peak volume flow calculation (m3/s) over the 24 hour condensed sizing period.
Or as depicted in a chart:

This file is a result of the zone sizing calculation. Zone Sizing (see Sizing:Zone object) performs a special calculation, using a theoretical ideal zonal system, and determines the zone design heating and cooling flow rates and loads, saving the results in the zone sizing arrays. The file has a similar format to the eplusssz. file.
