2017-03-02 20:53:47 -0600 commented answer How to compile Energyplus in Ubuntu 14.04 after souce code modifying?

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

@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.

2017-02-22 10:17:23 -0600 asked a question Adding an actuator to EnergyPlus

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?

2015-09-23 11:20:16 -0600 asked a question How to run EnergyPlus measures?

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+.
