Sustainability is much more than a buzzword for ION

We prove that sustainability is much more than a buzzword for us by actively striving to reduce environmental impact while increasing quality of life. We do so by setting up smart home systems and limiting concrete wherever possible. . In Wol U, for example, we’re preserving and renovating the former underground car park: a saving of more than 1,500 tons of CO2.

Smart use of geothermal energy

The apartments of Wol U are heated by geothermal energy : one of the most sustainable techniques for generating heat. This involves using heat generated from the earth itself, which is present in the subsoil, pumped up and used for heating by means of boreholes and an installation in the subsoil. This advanced technology, combined with the extensive insulation of the outer shell, results in an E-level of E30.
