@shorowit The command above with the "-r" option will not run the simulation. "-r" is short for --readvars, which runs

In addition to the zone humidistat, you also need to add components to the air system serving the zone that add or remov

The prototypes were recently updated to address Addendum av, which characterizes the new thermal bridging requirements.

If the callback function isn't too complicated, you could try to re-write it in Erl within the IDF as an EnergyManagemen

Good advice, always run/inspect the CSE and/or EnergyPlus files separately when the CBECC error message isn't helpful.

No, latent loads can be output for any zone with Output:Variable,*,Zone Total Internal Latent Gain Energy,hourly;

The workaround Scott mentioned above has worked for me, sometimes. I tried it on 3 different computers; it has worked on

Run this Python script to create a list of all IDFs in a folder (that you want to update): import glob, os f = open("u

@prophet please post a link to your IDF, this question is impossible to diagnose without inspecting the input file.

What HVAC equipment is serving the zone? Some equipment can be specified with a control type of Load or Setpoint. If the

EnergyPlus assumes zone air is well-mixed by default, so the addition of a ceiling fan would not aid in air circulation

These are EnergyPlus objects, I'm not sure whether they're available in OS.

You input these coefficients directly into the fan object. The dependent variable is full load power (PLF); the equation

The simplest, and most common, way to represent a DSP reset in EnergyPlus is to specify a different fan curve. Either th

There is a multispeed heatpump object as well as individual multispeed heating and cooling coil objects that can be used

Not sure about OpenStudio, but EnergyPlus has a ZoneHVAC:WindowAirConditioner.

See the IDF I linked in my previous response, it runs without error.

Ok it's because the Fan Operating Mode Schedule is set to Always 1. Always 1 for a fan operating schedule means it'll al

You have a ThermostatSetpoint:DualSetpoint but no ZoneControl:Thermostat. You need to include a ZoneControl:Thermostat

No, it is common to have several versions of EnergyPlus installed on the same machine.

If the prototype models don't represent Baseline models (ECB Method), why are they developed for each code/standard year

ASHRAE/IECC Baseline VAV Fan Curves and Min Flow Fraction What are the appropriate fan curve coefficients and Fan Power

Spaces were introduced in EnergyPlus 9.6. As for the other questions, I don't know.

@Keigo interesting, thanks for that info. So, how would you determine the throttling range in a model? Wouldn't that req

You could potentially expand your tolerances for zone heating/cooling setpoint not met. If cooling setpoint is 21C and h

It seems you answered your own question (the CurveFitTool.xlsm that comes with E+). Are you asking about how to use this

Thanks for this detailed explanation Aaron!

You can download a Windows executable for DView here.

Maybe it's because the cooling towers are not achieving the entering condenser water temperatures at the PLRs in that ta

You only need to specify one heating design day and one cooling design day, but if you specify more than one, loads are

You can always upload files to the cloud and post a link. Glad you found a solution.

You used the unitary system template (HVACTemplate:Zone:Unitary) which, when expanded (see the *.expidf), creates a Sizi
