Positive stress happens when there is more air being provided than worn down, and prevails to minimize the infiltration of outdoors impurities. All-natural air flow is a key factor in helping to reduce the spread of airborne diseases and diseases such as consumption, the usual cold, flu and meningitis. Natural ventilation is the most convenient and easiest form of cooling and heating as it calls for little to no maintenance, is typically free or a minimum of affordable as can be given by something as easy as opening up doors, windows, or use ceiling followers are all ways to enhance natural ventilation and as a result reduce the threat of air-borne contamination.

Solutions with tiny storages can be hybrid, utilizing free cooling at the beginning of the warmer period before changing to a warmth pump to further cool the blood circulation originating from the storage later in the period. These heat pumps are added-in since the storage serves as a warmth sink when the system is in air conditioning (in contrast to billing) mode, triggering the temperature level to gradually boost during the air conditioning period.


In both cases, the outdoors air needs to be much less energised than the return air for the system to get in the economiser mode., and public structures throughout building and construction, however because they require a network of large air ducts throughout the structure they are extremely tough to retrofit (mount in a structure that was not developed to receive it).
