About ARTEA

ARTEA, a pioneer in energy transformation, was founded in 2001 with the aim of offering a new vision of real estate that differs from contemporary approaches. Currently, the group offers an integrated model of circular economy based on three main principles:

Its decentralized consumption model, based on intelligent, local, and managed infrastructures, aims to achieve carbon neutrality by 2030, implementing the "Double Zero" strategy: zero carbon, zero fossil fuels.
