Getting 'Annual Visual Resilience' summary reports (in html file) using design builder (for Jeplus parametric analysis)

asked 2025-06-18 17:16:50 -0500

ajith's avatar

I am trying to obtain an annual summary of indoor illuminance results (such as the percentage of occupied hours with illuminance levels <300 lux, etc.) from DesignBuilder simulations for parametric analysis in jEPlus.

In OpenStudio, when using EnergyPlus daylighting controls and reference points, such illuminance metrics are available in the EnergyPlus output HTML (e.g., "% occupied hours below 300 lux" in the Annual Visual Resilience summary section). However, in DesignBuilder (I am using v6.0.1), even after enabling "All Summary Reports," I cannot find a similar Annual Visual Resilience summary in the output.

I understand that when using the Radiance engine in DesignBuilder for daylighting simulations, the results are not written to the EnergyPlus output HTML file, but rather to Radiance-specific reports. How can I configure DesignBuilder to generate the desired illuminance section ' Annual Visual Resilience summary in the EnergyPlus output HTML file — similar to what OpenStudio does — so that the results can be easily used for parametric analysis runs in jEPlus?

Just add "VisualResilienceSummary" to the SummaryReports definition in the exported IDF should do the trick.

For example:

Output:Table:SummaryReports,
    AnnualBuildingUtilityPerformanceSummary,    ! Report 1 Name
    DemandEndUseComponentsSummary,              ! Report 2 Name
    SensibleHeatGainSummary,                    ! Report 3 Name
    InputVerificationandResultsSummary,         ! Report 4 Name
    AdaptiveComfortSummary,                     ! Report 5 Name
    Standard62.1Summary,                        ! Report 6 Name
    ClimaticDataSummary,                        ! Report 7 Name
    EquipmentSummary,                           ! Report 8 Name
    EnvelopeSummary,                            ! Report 9 Name
    LightingSummary,                            ! Report 10 Name
    HVACSizingSummary,                          ! Report 11 Name
    SystemSummary,                              ! Report 12 Name
    ComponentSizingSummary,                     ! Report 13 Name
    OutdoorAirSummary,                          ! Report 14 Name
    ObjectCountSummary,                         ! Report 15 Name
    EndUseEnergyConsumptionOtherFuelsMonthly,   ! Report 16 Name
    PeakEnergyEndUseOtherFuelsMonthly,          ! Report 17 Name
    VisualResilienceSummary;                    ! Report 18 Name

@Yi Zhang,

Thank you sir. It works. As per my understanding, while modelling in DesignBuilder, we just have to switch 'on' lighting controls, specify lighting levels, required lux, etc. and then add the 'Visualresiliencesummary' in the IDF file for analysis in Jeplus. Please let me know if something else has to be kept in mind while doing these tweaks.

Yes, I think so. According to E+'s documentation, you only "need to define the Daylighting:Controls and the Daylighting:ReferencePoint objects, even if no daylighting controls are actually implemented in the building simulation model"
