Science and engineering issues related to providing a city like Berlin with water and energy, removing its waste, and moving people into, out of, or around the city. Simple analyses focused on mass balances for a city, i.e., how much energy, how much CO2 generated, how much water and for what purpose is it used. "Back-of-the-envelope" calculations typical of much engineering to understand the scale of various issues, problems or the solutions to those problems. Particular challenges faced by the city due to climate change, and to what extent Berlin (and Germany) is engaging in policies designed to adapt to or reverse climate change. What makes a city "sustainable" and livable. Field trips to particular technological and environmental features of the city.
