  spaces_array = BTAP::Common::validate_array(model, spaces_array, "Space")
  thermal_zone = BTAP::Common::validate_array(model, thermal_zone, "ThermalZone")[0]

end

.filter_core_spaces(model, spaces_array) ⇒ Object

This method will filter an array of spaces that have no external wall passed floors. Note: if you wish to avoid to create an array of spaces, simply put the space variable in [] brackets Ex: get_all_surfaces_from_spaces( [space1,space2] )

Parameters:

  • spaces_array —

    an array of type [OpenStudio::Model::Space]

Returns:

  • an array of spaces.

.get_space_placement(space) ⇒ Object

This method will return the horizontal placement type. (N,S,W,E,C) In the case of a corner, it will take whatever surface area it faces is the largest. It will also return the top, bottom or middle conditions.

.get_spaces_from_storeys(model, floors) ⇒ Array<OpenStudio::Model::Space>

This method will return a SpaceArray of surfaces that are contained within the passed floors. Note: if you wish to avoid to create an array of spaces, simply put the space variable in [] brackets Ex: get_all_surfaces_from_spaces( [space1,space2] )

Parameters:

  • model
  • floors
