However, 5ZoneWaterCooled _Baseboard idf is not an easy example to follow.
In this example IDF, the water baseboard heater is used as an auxiliary zone equippment.
I have not look at all the schedules, etc. in detail. It appears to me that the baseboard heater will be used when the main air system is not sufficient or turned off.
If you know how to extract the requred objects for the baseboard heater from this IDF, you can form a much simpler IDF, with just the boiler and the pump and the baseboard heater. There is also a chiller in this example.
You may send me the extracted IDF and your building envelop, if you cannot get the reduced IDF to work.
By the way, you do not have to delete all the unwanted components, and change the building envelope. Simply change the settings of the available schedules for the different zones and
leave the one you want to operate. The chiller and the air terminals will all be turned off. This appears to be difficult, but is a process you should try, to understand how the schedule are working and interacting.
------------ --------- --------- ----
The second question, I am not sure whether you have mixed up the zones with rooms.
One Energy Pluse zone may have many rooms. However, you may only have one thermostat control per zone.
If you want two rooms, each with a thermostat, you cannot combined them into one zone, and you must have a air terminal in the zone which can be controlled by the thermostat.
You may have one air handler unit (AHU) feeding two zones (each zone with many rooms), one master zone with thermostat is temperature controlled. The other, slaved zone, receives a fixed proportion of air through a spliter and an air terminal with no control. (a
fixed damper) If the two zones have load demands that are not varying with time, the arrangment is usally very acceptable.
Many small/medium size offices are arranged this way with one or two AHU's per floor. The occupant will adjust the air diffuser damper slightly to suit their indevidual requiement in a common office area. Manager's room may have a thermostat controlled air diffuser, which may the room slightly warmer or cooler than the general area.
If the two rooms (zones) are not of the same size, you can set the damper to a different ratio, 0.5:0.5,(equal) 0.3:0.7, (small, large) etc. The total amount of air flow is that available from the AHU. The return air will be through a mixer or the plenum, which is not controlled.
The last paragraph may also answered the question posed by another member of this group on how to feed two
zones from one AHU using one duct.

hi
one simple example file which use also Zone HAVAC:Baseboard Convective Water as zone equipment to heat space is:5ZoneWaterCooled _Baseboard idf file.
second question I'm not clear what you mean.
good luck

Hello
I am writing to you because i have two questions
I am looking for the simplest example file in the energy plus that has space heating radiator (Zone HAVAC:Baseboard Convective Water) combined with a boiler. Or something similar to that, because I want to use the energy plus for space heating simulation.
Besides I would like to know if we can combine 2 energy zones to one, and how.
Thanks for
your time and consideration
