Globally, 10% of CO2 emissions come from heating and cooling buildings. Imagine a future where this is reduced to zero. The 'Google Maps of heat loss', Kestrix is the data layer to power a retrofit revolution. Unleashing the power of AI on drone thermal imaging, Kestrix constructs real-world 3D heat loss models of to inform energy efficiency retrofit planning, pricing, and verification at city-scale. So housing providers, energy utilities, and local governments can spend less time planning retrofits, and more time doing them. #GetRetroFIT
