The world is a changing place, and we are seeing this in our climate and weather patterns. The change isn’t consistent, floods and temperature extremes are becoming more frequent, and often we are unprepared for these events. When it comes to our house, even though the weather in NZ is pretty comfortable for 2/3 of the year, we should be able to fully shut all of the doors and windows and still be healthy, comfortable, and well ventilated inside when the weather outside is not cooperating.
