Simulation tool determines CO2 emissions of air conditioning in buses

Even if we were able to reduce the fuel consumption of our vehicles to zero – we would still have to go to the gas station. One of the decisive reasons is the air conditioning, which heats the passenger compartment in the winter and provides cool air in the summer. Especially in buses, the additional energy consumption is tremendous. About one fifth of the energy or the fuel consumption and CO2 emissions are caused by heating and cooling technologies. So far, this fact has not been adequately taken into consideration. A tool by the Fraunhofer IVI resolves this problem.
