I’ve built a stand alone guest room & it gets very hot. It’s not too much of a problem on sunny days as it has sliding glass doors which when left open during the day ventilate the room pretty well. However, now we’re coming into the rainy season leaving the doors open isn’t an option so I need an alternative form of ventilation. If I was to simply put in some ventilation grilles in the ceiling & in the walls between the ceiling & roof would this make much difference? Would it be better to install electric extractor fans in the ceiling and/or a solar-powered roof ventilator? Any other suggestions?
Thanks.
