Thank you! this is a smart approach!

add new actuators by changing the source code of EnergyPlus I am working on an ASHRAE project for demand control ventila

Thanks a lot. That would be great help.

i need to generate a random number with bounds [lower, upper], every time step in EMS programming on EnergyPlus. How to implement this idea?

@Jason DeGraw. Thanks. I am still one step close to success, when i do "make -j N package", i got several similar errors. How to fixs them? A snapshot is as below:

Run CPack packaging tool... ... ...... ...... +++ AutoDocs: completed processing example file links summary: processed 513 files. install_remote failed, trying again: https://raw.github.com/NREL/EnergyPlu... error CMake Error at ....../cmake_install.cmake:334 (message): install_remote failed, trying again: https://raw.github.com/NREL/EnergyPlu... error

@Jason DeGraw, thanks alot. I got some error during the ccmake . The error said: No GITHUB_TOKEN found in environment; package won't be complete. Call Stack(most recent call first): CMakeLists.txt:190(include). Do i need to use my own github account? or what else?

Thanks a lot. what does the mean of EnergyPlusTeam as in the sentence: "ccmake ../EnergyPlusTeam"? I did not find file name of EnergyPlusTeam.

thanks. what does this paragraph mean as below for compiling?

Navigate in the terminal to the root of the build tree. You will launch the cmake GUI from this location. The program must be passed an argument that specifies the location of the root of the source tree. For example, if the build directory is directly next to the source directory, the command could be called for the default build environment by calling the GUI as such: ccmake ../EnergyPlusTeam

I did not find a executable named: EnergyPlusTeam

i modified some part of the source code of EnergyPlus, and i need to recompile them. i am using Ubuntu 14.04. How to recompile them? what environment/libraries will be needed for recompiling? Thanks

@Adam Hilton. Thanks. I am trying to do the sensitivity analysis of sensor accuracy through EnergyPlus. In such case, i need to manipulate the values of sensor readings with some errors for the zone CO2 concentration. So i need to create an actuator in EMS for zone CO2 concentration.

thanks @rraustad. I am doing the sensitivity analysis for zone CO2 sensor accuracy. I need to manipulate the zone CO2 concentration.

yes. overwrite the zone CO2 concentration.

thanks. i am talking about the EMS.

I am doing CO2-based demand control ventilation, i need to add an actuator for EMS programming: Zone_CO2_Concentration.

Details of my idea: assume the sensor readings of CO2 sensors have faults in real buildings, and the readings have some deviations. The demand control ventilation rely on the accuracy of sensor readings of CO2 concentration. I try to implement such a problem in EnergyPlus. In EMS there is a sensor: zone CO2 concentration, and during each timestep i try to add some deviations to the sensor results in EMS, send it back to the EnergyPlus by actuator of EMS for next timestep calculation. Such approach will make different responses to DCV and thus different building energy consumption. I will need to conduct large scale simulations for about 10000 cases, and study the sensitivity of sensor readings to the building energy consumption.

current actuator list does not have such actuator for EMS. how to implement this?

when i create OpenStudio measures, i find it is possible to create Energyplus measure? How do i implement the Energyplus measure? Do i need to run the E+ measure through OpenStudio, which will finish the desired task in the back? Or do i need to import the E+ measure into energyplus to do the desired task? But it seems no place to import energyplus measure in E+.
