@kflemin Jenkins passes all the tests but fails the rake task and still sets the build to green. I'm looking forward to relying on GHA instead of Jenkins.

Refactoring to not require number_of_stories (as requested in #232) would take some thought. It, along with floor_to_floor_height, is used for the shading calculations in building.rb & helper.rb. Using maximum_roof_height and/or roof_elevation would not help because those aren't available with os-hpxml or osm either.
