Solutions with little storages can be hybrid, using free air conditioning at the beginning of the warmer season before changing to a warm pump to further cool the flow coming from the storage later on in the season. These heat pumps are added-in due to the fact that the storage space functions as a warm sink when the system is in air conditioning (in contrast to billing) mode, causing the temperature level to gradually raise during the cooling period.

In both cases, the outdoors air has to be less energetic than the return air for the system to enter the economiser setting., and public structures during building and construction, however due to the fact that they call for a network of huge air ducts throughout the structure they are extremely tough to retrofit (install in a building that was not developed to obtain it).
