Floor cooling: Can I use floor cooling instead of aircon?

Generally in our Australian climates, floor cooling is does not cover the required cooling load of the building. This is partially due to the way we build our houses in Australia (lots of glass windows and doors, varying levels of air-tightness and insulation), but also because there is ‘latent’ load which needs to be removed from the air (heat held in air moisture), and mainly due to the fact that physics works against floor cooling, because cool air remains close to the ground and warmer air remains above this uncooled. Floor cooling output can be between 20-50W/m2, whereas the cooling load for typical houses can be around 150W/m2, and for more energy efficient house around 70W/m2.
