I get those following codes from os_lib_reporting.rb file. Plesae give me some instruction for change them into SI unit of value and unit shown in result.

result First type:

type: # EUI
    eui =  sqlFile.netSiteEnergy.get / query_results.get
total building area
    query = 'SELECT Value FROM tabulardatawithstrings WHERE '
    query << "ReportName='AnnualBuildingUtilityPerformanceSummary' and " # Notice no space in SystemSummary
    query << "ReportForString='Entire Facility' and "
    query << "TableName='Building Area' and "
    query << "RowName='Total Building Area' and "
    query << "ColumnName='Area' and "
    query << "Units='m2';"
    query_results = sqlFile.execAndReturnFirstDouble(query)
    if query_results.empty?
      runner.registerError('Did not find value for total building area.')
      return false
    else
      display = 'EUI'
'Total Building Area'
      source_units = 'GJ/m^2'
'm^2'
      target_units = 'kBtu/ft^2'
'ft^2'
      value = OpenStudio.convert(eui, OpenStudio.convert(query_results.get, source_units, target_units).get
     value_neat = OpenStudio.toNeatString(value, 2, 0, true)
     general_building_information[:data] << [display, value_neat, target_units]
     runner.registerValue(display, value, target_units)
    return general_building_information
  end
