This paper discusses the potential for energy savings in heating and ventilation of light rail vehicles. We present the results of a detailed monitoring campaign on one articulated tram in Ghent, Belgium. The results give insight in the energy use for heating and ventilation in light rail as a function of ambient weather conditions. After several months of monitoring, changes in the HV strategy were implemented and the monitoring was continued. Based on this monitoring data, an energy-use model was constructed for HV both before and after the heating and ventilation strategy changes. These models then served as input for a Monte Carlo simulation, providing average energy savings over 1 year as a result of the optimized heating and ventilation strategy.
