After reading through various questions/responses from Unmet Hours and trying many things, I am still unsure how to accomplish what I need. The scenario is:

Designing the HVAC equipment for a new construction building, which first requires the peak heating and cooling loads (sensible and latent) per thermal zone (each room of varying equipment/people loads).

Previously, we have tried turning on various output variables (including Zone Total Internal Latent Gain Energy, Zone Total Internal Latent Gain Rate, Zone Ideal Loads Zone Sensible Cooling Rate, Zone Ideal Loads Zone Sensible Heating Rate, Zone Ideal Loads Zone Latent Cooling Rate, Zone Ideal Loads Zone Total Cooling Rate, Zone Ideal Loads Zone Total Heating Rate), but I believe these only offer either the sum or average of all the zones, while I need values for each zone; we have read through the Input Output Reference; we have tried enabling ideal air loads with and without mock equipment in each zone. Maybe these are working, but then we are also having trouble finding WHERE the information is outputted. The csv file only shows the same four values per thermal zone: "Des Heat Load," "Sens Cool Load," "Heat Mass Flow," and "Cool Mass Flow." We have looked through the idf files as well as rdd and still no luck.

We simply would like the peak sensible/latent heating/cooling loads per thermal zone to be outputted. What am I missing?

I am also interested in the answer to this question!

I noticed that this question may indirectly answer this question: to find peak sensible/latent and/or heating/cooling loads per thermal zone, you need to assign systems to each zone. It seems from this answer, that only multi-zone systems give you the option to output latent loads. I have also asked a similar question here.
