For existing buildings, the measure of total square feet occupied (indicated as a Move-In) over a given period of time with no consideration for space vacated during the same time period. Sublet space and lease renewals are not factored into gross absorption. However, in a lease renewal that includes the leasing of additional space, that additional space is counted in gross absorption. Preleasing of space in non-existing buildings (Planned, Under Construction or Under Renovation) is not counted in gross absorption until actual move in, which by definition may not be any earlier than the delivery date.
