An energy audit is a comprehensive assessment of your energy consumption, allowing you to identify potential savings and prioritize your investments. It is mandatory every four years for companies with more than 250 employees or a turnover exceeding €50 million. Beyond the legal requirement, it is the essential starting point for any serious energy efficiency program.
