We've searched the forum for an answer to this but couldn't find one, if anybody can answer this question or point us at a thread which already answered it - we'd be grateful
We have a two story building in the Capital, with 7 rooms - all of which are used part of the time but none is used all of the time.
Airconditioning options are either fitting each space with an individual airconditioner which can be switched on and off as needed, or installing a central system (or perhaps one central system for each storey) and having individual fan-coil units in each space which can be switched on and off as needed.
Assuming that the difference in equipment and installation costs and electricity supply are not the issue, but that the cost of electricity is - does anyone have any reliable (preferably practical rather than theoretical) experience as to which of the options would be intrinsically less expensive to run??
