We are using following code snippet to generate OpenStudio prototype building using OpenStudio-Standards. (Small office building, ASHRAE Std 2007, Climate zone 3B)

@primaryUseType = "SmallOffice"
@template : 90.1-2007
@standard : ASHRAE 169-2006-3B
@weatherFile = Dir.pwd + "/data/" + "USA_CA_Los.Angeles.Intl.AP.722950_TMY3.epw"

@model = OpenStudio::Model::Model.new()
@model.create_prototype_building(@primaryUseType, @template, @standard, @weatherFile)

There are differences in building construction and hvac terminal unit type between EnergyPlus prototype building downloaded from here and OpenStudio prototype obtained from running code snippet above. Can any one please shed some light about these differences? Is there a known issue with this and other differences or something is wrong with our approach? Any inputs on this is most welcome. Many thanks.
