Hi there looking for some advice on keeping a couple of bedrooms cool in our house. I can’t seem to find anything that seems authorities on the internet (go figure). We have a two level late 80’s house brick and weatherboards, with a concrete tiled roof. The children’s bedrooms are on the east side, so get the morning sun, so we usually keep the blinds down. However, although no sun in the afternoon, they are really hot. Pretty tricky as we have a 6 month old that we would like to get sleeping in the afternoon and early evening. I’m thinking of installing some kind of vent system. Perhaps from the ceiling of each room to the outside. If so is it better to bring cold air in or vent hot air out? I see smart vent have some kind of ‘summer’ system, is that what that is doing. If so I could look at their system. Any experience people have had then using them to cool rooms?
