The document discusses polygeneration in the city of Växjö, Sweden. It describes three steps in Växjö's cooling project: 1) installing absorption cooling at VEAB, Växjö's energy company; 2) providing absorption cooling to the University and Central Hospital; and 3) providing absorption cooling without grants. The cooling project benefits customers through lower costs, the environment through reduced emissions, and the energy company through increased revenue streams.
