2020 Sustainability Report| Global challenge | 63 Reduction of energy consumption Every four years and since 2016, Aqualia has subjected In 2020, the office building in Las Tablas, where Aqualia itsinstallations to energy audits. To monitor the has its headquarters, was certified in terms of energy improvement opportunities detected in these audits, management. Consumption is expected to be optimised there is a computer tool that will be integrated with in this building that, as in the case of the rest of the Aqualia's technical reporting/analysis tool (AqualiaRT/ offices, has a much lower impact on the company's AqualiaBI) that will enable the actions and results carbon footprint than the production installations, but obtained to be monitored. which are Aqualia's showcase for its end-clients and for allits employees to whom in this way the company's environmental commitment can be transferred.
