What EnergyPlus report to use for coil sizing selections?
I need to run loads in OpenStudio 1.11 to size equipment for a commercial 5 story office building. Where in the output reports can I find the following information?
system total cooling coil capacity (MBtu/h);
system total heating coil capacity (MBtu/h);
system design air flow rate (cfm);
outside air flow rate (cfm);
The building will run on district chilled water and have several systems with chilled water fan coils, electric heat, and parellel fan powered boxes. There is also a dedicated outside air system that I need to account for that will deliver neutral air to the air handlers. I am running one zone per system. Here is a screen shot of one of my systems.
I have looked in the E+ output report under "Equipment Summary" and "HVAC Sizing Summary" but have found the design loads and nominal total capacities give conflicting information. I understand the coils show design loads with fan and electric power, the nominal capacity does not have fans nor electric power, and the zone sensible is sensible without system effects nor ventilation loads. My "Cooling Coil Nominal Sensible Capacities" are almost double my "Sensible User Design Cooling Loads".
Have you looked at the "Component Sizing Summary" in the E+ output report?
That is where I am looking, too. It appears to have all the necessary information, but - at least under my configuration - it shows it in W and m3/s. Is there a way to quickly and easily get kBTU/h, ton, cfm and gpm from those? Alternatively, can the Component Sizing Summary be exported to a spreadsheet? Thanks.
@Matt Koch You could write a reporting Measure that unit converts and saves to CSV or you could open the report in a web browser and copy/paste the table to Excel.
@Matt Koch the Set Output Table to IP units measure might help. However, it does interact with the standard OpenStudio report.
