Hi, I tried taking one of the 90.1-2016 prototypes (https://www.energycodes.gov/developme...) for Small Office, updating it to EnergyPlus 9.2 using the IDFVersionUpdater, and importing the updated .idf in OpenStudio 2.9.1, and I get this error:

File is not valid to draft strictness. Check that IDF is of correct version and that all fields are valid against Energy+.idd.

I've pasted the error details below but before I go too far down a rabbit hole, is there an easier way to get the 90.1-2016 prototypes into OpenStudio format? Thanks!

Thanks for the reply! I've just "thumbs upped" that feature request.

With EnergyPlus is it possible to assign individual coils to end-use subcategories? I don't see the end-use subcategory field for the coil objects like i do for fan objects. I'd like to break out energy consumption by system in the html tabular output.

I am working with a high-rise apartment model in EnergyPlus v9.2; it's a modified DOE prototype, with one modification being the addition of baseboard heating via the ZoneBaseboard:OutdoorTemperatureControlled object. I am trying to get the annual electric energy consumption for all of these baseboard zone objects reported in the html output.

I attempted to do this by defining an Output:Table:Annual to sum the Zone Baseboard Electric Energy [J] Output:Variable. What I've noticed is that the Output:Variable doesn't appear to take floor multipliers into account. This model has one ground floor, one mid floor with a multiplier of eight, and one top floor; but the mid floor Zone Baseboard Electric Energy [J] Output:Variables are 1/8 of what I'd expect. It appears that this is as designed: https://github.com/NREL/EnergyPlus/is...

If this is truly how the output is meant to be reported (without the multiplier applied), how can I go about getting the true total annual electric energy consumption for all of the baseboard zone objects included in the html output?

Much thanks for the info!

I've just used the "Create Typical Building From Model" OpenStudio measure on BCL and set the Service Water Heating Source option to HeatPump; after applying the measure I noticed this funny warning:

Warning: [openstudio.model.Model] Simple but crappy workaround to represent heat pump water heaters without incurring significant runtime penalty associated with using correct objects.

Does anyone have more insight into this warning, i.e. what is the workaround being used and what would be the "correct" objects to use? The measure added an OS:WaterHeater:Mixed object with a Part Load Factor Curve Name of HPWH_COP_2.8.

Yes, my understanding is that the unregulated energy cost is meant to be the same for both the baseline and proposed sce

I don't have the SketchUp plug-in and am trying to create a building in OpenStudio 2.9.1 with the built-in Geometry tool (using FloorspaceJS); I want to set the Space Types to represent a primary school and try using the "Create Typical Building from Model" OpenStudio measure in BCL but the only Space Types showing up in my Library are for an office building.

So cool - it worked! Thanks again.

Thanks very much - I'll give this a try!

Is it possible to use tabular output to report average demand over a specific period with EnergyPlus?

I want to add a table to be included in the eplustbl.htm file that shows "peak demand" as defined by a particular utility or region (ex. California DEER peak demand savings are the average kW reduction over a 9-hour window - 2pm to 5pm over a three-day period).

I currently do this via post-processing of hourly output:variable output, but I was wondering if EnergyPlus can do the averaging for me somehow and report it in the .htm file.

Just wanted to add, I found an output variable in the .rdd file called Site Daylight Saving Time Status that is either a

It appears EnergyPlus can account for daylight savings time but doesn't update the timestamp in hourly output - from this it sounds like hourly output timestamps are not shifted ("reporting is always in standard time") but schedules are: https://bigladdersoftware.com/epx/docs/8-5/tips-and-tricks-using-energyplus/schedules-off-by-1-hour.html

Is it possible to have EnergyPlus output daylight savings time instead of (or in addition to) standard time?
