Report on capacity of improvement of actual services

For each element of each site, three key factors will be investigated : energy efficiency, energy mix and load factor. The energy mix could have a huge impact on the greenhouse gas emissions, but it could have an adverse effect on the energy consumption. It is often hard or nearly impossible to win more than 20 or 30% in energy consumption, greenhouse gas emissions and air pollution (not just one indicator). In that case it might be better to radically change the service. The aim of this part is to identify the limits of improvement on the actual situation.
