Is the Zone Air System Sensible Heating Rate the energy the system used?

I want to know, if the Zone Air System Sensible Heating Rate is the energy, which is used by the HVAC.

In Input Output Refernce is declared that is the energy which is influenced by the environmental. Look at Output Input Reference

These values are calculated by multiplying the supply air mass flow rate by the difference between the supply air temperature and the zone air temperature. This does not always indicate the operation of heating or cooling coils. For example, cooling will be reported if the supply air is cooled due to the introduction of outside air, even if all coils are off.

I want to have the energy, which is used by the HVAC without influence of the environmental and I need it hourly. I can´t find the right one. Which I should take and how do I get it in OpenStudio? Thanks for help

What's your HVAC system?

Also, clearly the answer is no, because it's not homogeneous in terms of dimensional analysis. Heating Rate is in Watts (J/s), Energy is in Joules.

The HVAC is an system with hotwater baseboards and a boiler. There is no cooling. Therefore I have to sum the Energy from the output from the components of the HVAC?

I don't understand your "I want to have the energy, which is used by the HVAC without influence of the environmental"

The Zone Air System Sensible Heating Rate is the Energy which is calculated by the Zone Air with influence of heating by sun or cooling of wind etc. But for the HVAC is used a special amount of Energy independent of the solar energy. I want the Energy which is used by the HVAC. Therefore it is the energy I have to provide to heat my model.
