Thanks hellbender, venting will be a priority since although im coastal now im not sure once I find a house. Relatives who live farther inland complain of no air flow. To me I see it more as how they build their houses. Walls on hottest sides no venting of rooftops nowhere for stale air to flow. Will really have to look into building materials ive got a few lumber places nearby but not anything like in states. Even something like ceiling fans I have yet to see here. Can find vented fans they use in kitchens and restaurants. Gypsum board is new here too. Only for stores not in homes yet.
