 My name is Alice Chang-Riches. I'm a lecturer from the Department of Civil and Environment Engineering. It started with a random conversation with some of my friends who are medical professionals. They have seen quite unusual increased hospital admissions for young children and elderly people, and they suspected that maybe because of the very strange weather they had last year, it might be due to the unhealthy housing issues. In New Zealand every year we have more than 20 children die as a result of respiratory diseases like asthma and rheumatic fever. They made me ponder this problem not from the public health perspective, but also from the engineering perspective. In New Zealand currently we're building houses in a way we built many years ago. At the same time our building codes hasn't really affected the impact of climate change. As the temperatures get warmer and we got more wet weather, there would be more potential respiratory health hazards for at-risk populations. They are more prone to illness and other health related issues. So what we try to do is gain improved understanding about our housing system. How a changing climate can affect the healthiness of a home and then affect the health of the children living in that house. Then we will be able to tell the housing agencies and government about the critical dynamics at play in a house outside a house that would differentiate the health outcomes in home.
