the end use of low radiant floor heating is too low in the os report

Hi everyone,

I am doing a simulation for a radiant floor heating system. Now I am using a template found in BCL(by apply measure). The HVAC template I used named AEDG Office HVAC radiant DOAS. My building is a residential building with 6 stories plus 2 parking lots underground. There are 36 units in the building.

Now after the simulation, the report shows that heating only accounts for 10% for the total end use, while lighting and interior plug loads occupy 48% and 40% respectively. That does not make sense to me. My understanding is heating should be the largest part, around 50%~60% for the total energy consumption.

I tried to adjust the heating schedule. The original setpoint is 18 degree c for heating, I change to 40 C(I guess whenever T below 40C, the radiant heating system will start to work?) However I still get the same number, 10%. I also check the definition for lighting and internal equipment, there are like 4 W/sq meter. Therefore, I guess there is something wrong with the heating only. The number is too low. And when I read the natural gas consumption for heating, the peak shows in Jan and Dec, only 17 MBTU(which is 5kwh). 5kwh one month for the whole building thats ridiculous

Does anyone know how to fix it? Thanks for any help.
