* to enable all windows and doors to be closed and the room's air is refreshed on a regular healthy basis.


* in summer to bring down temp inside the house during hot summer DAYS - regardless of whether someone is home or not so home is not 'stuffy', but pleasant (i.e. set to desired temp within reason)


* in summer to enable the system to cool DOWN the air temp inside the house throughout the NIGHT during hot barmy summer nights (if wanted)


* to be able to 'flush out' smells (eg. cooking fish) using the system


* in combination with double glazing, background hotwater radiator system to 99.99% eliminate condensation buildup in the space.

* in winter near dusk, to be able to extract and use (if any) warmth in the ceiling cavity to delay the turning on of primary source of heating (eg. radiators)

We are thinking of installing heat exchange / heat transfer unit focused around this apartment for the following reasons:
