Leonard is the founder of Awaretag, a sensor and analytics platform that measures the insulation, heating, moisture and ventilation performance of homes. The company uses 3D techniques to visualise conditions to make it easier to see what to fix. Leonard wants to make the science of building performance and the ‘lived experience’ more accessible. He believes this helps speed up understanding of issues, and creates fairer outcomes in housing. The company is working with charities, surveyors, housing associations, councils and landlords developing new ways for sensor data and people to deliver positive outcomes in a changing world.
