Montmélian is known in France and Europe as a pilot city in the field of solar energy due to its implication since 1983. The town has 1,564 m² of solar panels that means 390 m² per 1000 inhabitants (10 times more than the national average which is 32 m²). Winner of the French solar championship in its category for many years, it is one of the four local authorities in France having been awarded in December 2007 with the European label Cit’ergie for his exemplary policy “Energy-climate”.

The project of Triangle Sud continues the dynamics of innovation. In his new local urban plan, the town’s objective is to host new people and meet the housing needs of tomorrow. Triangle Sud was confirmed as a future urban area with a strong environmental ambition: to make a neighborhood incorporating a solar heating system with a solar thermal fraction of 80 % of the heat demand.
