Integrate OpenStudio-Standards into FloorSpaceJS to Speed Up Model Development

Implement OpenStudio-Standards Space Types in FloorSpaceJS

FloorSpaceJS is an awesome drawing tool for the OpenStudio ecosystem (if you're an energy modeler and haven't tried it, its a great alternative to SketchUp so take it for a spin!). One feature that I really wish was implemented however is first class support for OpenStudio-Standards - that is, implementing space types, loads, constructions, and schedules from the project automatically.

FloorSpaceJS has a nice feature that allows the import of a library file - the file consists of JSON containing space types and constructions and rendering colors. The trouble is that they are just strings; nice to have for organizing your model components but inherently disconnected from the data required by OpenStudio and EnergyPlus. Thinking about this problem I came up with a solution - inelegant considering that I would much prefer these things to be built right in, but hey, we do what we can.

In Superstudio you can now export a library JSON file containing types from OpenStudio-Standards templates; the library file includes randomly created color renderings as well so you can take advantage of that feature in FloorSpaceJS. If you clone down the repository you can export a file in one line:

# give permission to the superstudio CLI first:
chmod +x bin/superstudio

bin/superstudio export --template 90.1-2004 --building_type LargeHotel --output ./hotel.json

# you can also use the rake task 
rake test_export

exporting a library file

So now you can import that file directly into FloorSpaceJS: import library

After you complete the geometry for your model, export the FloorSpaceJS model and use the superstudio CLI to merge OpenStudio-Standards data into an OSM along with your geometry:

./bin/superstudio --debug --create -t 'LargeHotel' -z 'ASHRAE 169-2006-5A' -s '90.1-2004' -p './test/denver-model' --weather --epw ./test/data/USA_CO_Denver.Intl.AP.725650_TMY3.epw --ddy ./test/data/USA_CO_Denver.Intl.AP.725650_TMY3.ddy --geometry --json ./test/data/floorplan.json -a true

You should see your terminal spit out the following: model merge
