Office Buildings outside the U.S. should use the Energy Star Portfolio Manager to benachmark their energy performance. Do the energy consumptions entered to the protfolio manager have to include user electricity (for computers etc.) or does the Energy Star look at consumptions of the main building operation only? This would have a strong influence on the benchmarking result.

How would energy consumptions in multi tenant buildings be tracked? Is it common in th U.S., that the building owner /property manager has access to the consumptions of his clients?
