In my opinion you shall report the CO2 concentration at hourly interval and then using excel you can easily identify when is higher than 1500 ppm (or directly on the graph)
You can use the Output:Table:Annual object where you specify "Maximum" for the Aggregation Type field. This will tell you both the maximum value and the time the maximum value occurred.
Thanks for the suggestion. I think it would be useful. Is it possible to tell us the duration that the co2 concentration is more than a specific value in the run period? For example, 2 hours of the whole day, co2 concentration will be higher than 1500 ppm.
Ah, sorry, I misunderstood that you want duration, not an instantaneous time. I think the only way to achieve this is to create an EMS program with a variable that increments when the CO2 concentration is above 1500. You could then request that EMS variable as an annual output variable. I believe you would also need to specify the EMS variable as an EnergyManagementSystem:GlobalVariable so that its value is preserved across each execution of the EMS program for a new timestep.
