Hi everyone!

Someone can suggest me which Output:Variable should I select in EnergyPlus in order to segregate all heating loads by source type? I would like to get a pie chart showing the one which contributes the most with heat to the thermal zones: Lights, Electric Equipment, People, Walls, Ceillings, Floors, Windows or Infiltration. Well, if there is another one which I forgot, please let me know.

I've already tried these ones:

• Zone Lights Electric Energy [J] and Zone Electric Equipment Electric Energy [J], for lights and electric equipment, respectively.
• For People, I'm not sure if I sum Zone People Sensible Heating Energy [J] with Zone People Latent Gain Energy [J] or I select directlly Zone People Total Heating Energy [J]. Seems like the the sum of sensible and latent is different from total heating energy.

Thanks in advance!

Energyplus: is it possible to increase the variability of power demanded for a chilled water plant? Hi everyone! I have

Hi everyone!

I have this Energyplus model which simulate a hospital building energy consumption. The building has 3 air-cooled chillers with a total capacity of 220 TR which deliver only cooled air. The system has 27 fancoils and 4 pumps without modulation. Comparing the real and simulated plant shows a big deviation: to illustrate, I plotted the measured data and Energyplus output (time axis over X) for a little period (temperure of outdoor air included).

As you might remark, the measured data has a great variability! To put in numbers, the standard deviation for measured data is about 34 kW (whole measurement period), while the simulation stands for 5 kW (almost seven times lower).

I am wondering which setting I can change in my model in order to increase the power demand variability for the chilled water plant. Some attempts that I already tried without success:

 - Change Chiller COP;  - Change Chiller Flow Mode from NotModulated to LeavingSetpointModulated;  - Change constant speed pump to variable speed;  - Change constant volume to variable volume.

Someone can help me in this issue?
