Natural ventilation is a key consider helping to minimise the spread of air-borne diseases and ailments such as consumption, the acute rhinitis, influenza and meningitis. Natural air flow is the easiest and most basic type of cooling and heating as it calls for little to no maintenance, is often complimentary or at the very least affordable as can be provided by something as easy as opening up doors, home windows, or usage of ceiling fans are all ways to increase all-natural ventilation and therefore reduce the risk of air-borne pollution.

Systems with little storages can be hybrid, using totally free cooling at the start of the warmer season before changing to a heatpump to more cool the flow coming from the storage later in the period. These heatpump are added-in because the storage space functions as a heat sink when the system remains in air conditioning (instead of charging) setting, causing the temperature to progressively increase throughout the cooling season.


In both instances, the outdoors air needs to be much less energetic than the return air for the system to go into the economiser setting., and public buildings during building and construction, nonetheless since they need a network of large air ducts throughout the building they are really difficult to retrofit (mount in a structure that was not made to obtain it).
