Thanks for your answer, I want to check about something... i measured the SHGC by dividing Surface Window Transmitted

calculate dynamic SHGC for Electrochromic glazing hi, i want to calculate SHGC on energy plus hourly for example in 21

glazing properties (visible transmission) output I am working on Energy Plus and modelling dynamic glazing which change

Can any ony help me with how to dynamic horizontal overhang width more than 1 meter??????

this what I did exactly, for dynamic shading, to have 3 windowMaterial: blind with different slat angle (30,60,135) and to have three construction with these three blinds, and to design EMS Program to change these three constructions according to temperature ( like the idea of thermochromic glazing )

I want to ask, how to have a dynamic horizontal sun breakers with EMS with wide more than 1 meter because the blind are not more than 1 meter?? @JasonGlazer

my work is with accumulating between electrochromic glazing with dynamic horizontal and vertical shading with wide more than 1 meter, I used energy plus, but I was asking if there is another simulation program may be more efficient with dynamic shading ???

Which tool - EnergyPlus or grasshopper -is the best to simulate dynamic glazing like electrochromic glazing and dynamic shading? Why?

for dynamic shading, how to have a dynamic horizontal sun breakers with EMS with wide more than 1 meter, because the blind are not more than 1 meter??

thank you for replying

for dynamic shading, I want to chek if is right or not, to have 3 windowMaterial: blind with different slat angle (30,60,135) and to have three construction with these three blinds, and to design EMS Program to change these three constructions according to temperature ( like the idea of thermochromic glazing )???

@JasonGlazer

In case of using dynamic glazing and shading in EnergyPlus, how can I output the hours of each condition, that the shading was closed, opened, and partially shaded?

CAN ANY ONE HELP ME which is the BEST way to report glazing dynamic glazing which has many states from clear to dimming, from WINDOW LBNL to energy plus in WINDOW there are two ways: 1- idf file 2- BSDF idf file for each state

if the BSDF is the best way, how can I combine many states together ??

@aaron sorry i cannot understand what have i do ??

A problem with inputting BSDF .idf from WINDOW to energy plus for Glz system

To report *BSDF IDF for all of the states of an electrochromic glazing system,* and in case of copying the( window material:glazing - window material: gas - window thermal model: params - construction : complex fenestration state) which in the BSDF.idf generated from WINDOW LBNL to my case study .idf file it shown like the picture what can I do input the four states of the Electrochromic glazing to my idf file to control them with EMS ?? is way is right or any one have another suggestions?

thank you so much

I have a problem with the EMS for dynamic blinds for windows in three facades of the building can any one help me with it??` Here what is errors file says:

* Severe * Problem found in EMS EnergyPlus Runtime Language. * ~~~ * Erl program name: SET_SHADE_CONTROL_STATE * ~~~ * Erl program line number: 1 * ~~~ * Erl program line text: SET INCIDENTANGLERAD = @ARCCOS SOLAR_BEAM_INCIDENT_COS * ~~~ * Error message: * Error: EvaluateExpression: Variable = 'SOLAR_BEAM_INCIDENT_COS' used in expression has not been initialized! *

by using EMS for Switchable windows, it doesn't calculate the cooling loads for the zones .. can you help me with this ??? @maryam

@Roel Loonen by using EMS for Switchable windows, it doesn't calculate the cooling loads for the zones .. can you help me with this ???

@Julien Marrec by using EMS for Switchable windows, it doesn't calculate the cooling loads for the zones .. can you help me with this ???

but still my second problem that the cooling load doesn't calculate with EMS ?????

the EMS modelling approach can be considered a suitable alternative to the EnergyPlus built-in model, and it could also be successfully extended to other dynamic glazing technologies that do not have a built-in model available in EnergyPlus, provided that an accurate thermo-optical characterisation of the dynamic glazing is available.

EMSThermochromicWindow AND ThermochromicWindow in examples files, each one give different results so, which is the best way to add Thermochromic window to my modelling with EMS or with window material glazingGroup thermochromic ???

by using EMS for Switchable windows, it doesn't calculate the cooling loads for the zones .. Any one know WHY???

I am working on INTELLIGENT DYNAMIC GLAZING , by reporting the glazing from LBNL WNDOW 7.0 as idf. file and using it as a construction in energy plus, so usually the simulation processing loading stops writing "Entire ESO file treated as data dictionary - check for end of data dictionary line what can I do to solve this problem???

EP is installed in C drive

JasonGlazer can you help me

THANK YOU , but when i open errors it is empty

During the simulation stops and this message "Entire ESO file treated as data dictionary - check for end of data dictionary line." What i can do???

Here is the screen shot:

this what said in errors Eric Ringold

Unable to find required file while creating LocalProcess: Energy+.idd: C:/Users/ESS/AppData/Local/Temp/OpenStudio.o11452/resources/run/2-ExpandObjects-0/Energy+.idd basepath: [openstudio::RunView] <-2> Tree finished, status is: Failed

Eric Ringold i see the answer which you told me but i couldn't discover the error, do you have more information about what i could do?

thank you for your effort

in open studio running simulation, it doesn't do more than 75% and here what is written:

**FATAL:IP: Errors occurred on processing IDF file. Preceding condition(s) cause termination.
EnergyPlus Run Time=00hr 00min  0.39sec

My master is about intelligent dynamic window glazing glazing and shading, and using energy plus is not friendly, so I am trying to use OpenStudio and importing the intelligent window structure from WINDOW LBNL.

Are there any suggestions? How can I import IDF file from WINDOW LBNL to OpenStudio?
