CHARTER® as in “Territorial charge” is a modelling tool of seasonal time fluctuations, initially developed for the electric sector, permitting the representation of:

 Thermal charge for heating and hot water demands
 Fluids like water vapour
 Electricity charge on all levels of transport and distribution

CHARTER® is therefore particularly useful for dimensioning applications of transportation and distribution infrastructures, dimensioning production tools and calculating operational costs per usage. Moreover, the pedagogical character of this tool assures an undeniable role in consciousness raising. CHARTER® is used on all scales of the territories covered, from individual construction sites to urban development projects. It can be extended to countries, townships, regions and cities.
