I Have Been working in the model to submit to LEED and I had a similar problem in some of my zones. Without see your model, I would bet that you are having problems in the beggining of the ocupation. So, try to start your HVAC system before the occupation starts. Another important point is to create a thermostat schedule in small steps, I mean, do not set the 30° C and then 23 ° C. Make this transition gradually in order to prepare your zones to receive ocuppation (and other loads). The most part of my problems, I solved using this two strategies.
Unfortunatly, I still have two zones of my reference model that are presenting a big amout of unmetloadhours. I already identified the problem: in both cases, the unmetloadhours are happen between 14:00 and 16:00 as shown in in the pictures below, seems that the system do not have enough capacity to control this (currently, I am using a throttling range temperature of 0.5K; the area between the red lines in the picture below).
Any advice to solve it?
