It's called GENESIS: The Global Energetics and Environmental Simulation Suite, which is an airtight room which can recreate some of the world's most inhospitable climates.
From extreme heat and humidity to high altitude dry cold environments, the suite is opening up a whole lot of research possibilities about the way our bodies use energy in these conditions.
It can also be used for high performance athletes altitude and heat training.
Terry O'Donnell is Otago University's manger of Centre for Translational Physiology where the new suite is based.
