2024-02-25 11:35:57 -0500 marked best answer HVAC IdealLoadsAirSystem output metric

Hi!

I'm using EnergyPlus v23.2.0 to model a building and determine the amount of energy needed when I apply different natural ventilation strategies. To mesure the theorically energy demand that I must to provide to get a confort temperature I'm using the HVACTemplate:Zone:IdealLoadsAirSystem.

In the documentation I found that this template is preprocessed and transformed into a ZoneHVAC:IdealLoadsAirSystem object. But here I have a question. The documentation also indicate that the meters for the Template are DistrictHeating and DistrictCooling (InputOutputReference v23.2.0 p. 2530), and for the ZoneHVAC are DistrictHeatingWater and DistrictCooling (InputOutputReference v23.2.0 p.1269). So, which meter I must to use to calculate the energy demand? Heating:DistrictHeatingWater and Cooling:DistrictCooling or Heating:DistrictHeating and Cooling:DistrictCooling.

Thanks!

Hello. I am running a large number of simulations via the EnergyPlus Python API and I have the problem that it takes a long time to write the usual scrolling text during the run. I wonder if there is any way not to show it. I attach here an image of what I do not want to be displayed. Thanks!

2020-12-14 13:01:51 -0500 marked best answer Skip Warming in the simulation data exchange with Python API

Hi everyone. I am using the new EnergyPlus Python API in version 9.4. When I set the callback_begin_zone_timestep_after_init_heat_balance function from the Runtime API, I set a function to run when the simulation starts. In this way, with the Data Transfer API I obtain information on each time step and execute actions according to some calculations.

My problem starts when the Warming process is executed. During this initial stage of the simulation, the callback function is also executed, which I would like to avoid, because it hinders the information that I generate and then do a post-processing.

Is there a way to identify the beginning and the end of the Warming with the EnergyPlus Python API? Or any alternative to execute the callback function after the Warming process finishes? Thanks
