Andy is a professor of Climate Design & Sustainability at the Faculty of Architecture of TU Delft. He coordinates the Green Building Innovation research programme and responsible for the built environment theme within the Delft Energy Initiative. He founded the European Network for Sustainable Regions (ENSR). Already for quite some time he has been engaged with sustainable energy systems for buildings, neighbourhoods, cities and entire regions and therefore has developed methods to map the energy demand and potentials (Energy Potential Mapping, Heat Mapping). These can form the basis for a spatial plan based on a sustainable energy system or energy-neutral urban reconstruction (Rotterdam Energy Approach and Planning, Amsterdam Guide to Energetic Urbanism).

In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations)
