Running attic wires is easy - especially if the house has a chimeny. That chimeny means a hole exists all the way to the basement.
BUT fire codes have a stand off distance from chimneys,fire walls( fire proof walls to contain a fire) as do heating and cooling ducts.
what I was talking about was running wires thru closets that lign up from floor to floor ,
or if'n your feeling Gungy you can run said wires in side interior walls ,generally no insulation , but some time there are cross braces (
)
Or if all else fails you could run some pipe on the out side wall , this is a LAST resort as it costs more ( pipe , fittings , paint , sealer , etc,,, )
