Energy audits
All large enterprises would be required to undergo energy audits. These would need to start within three years of the directive's entry into force and be carried out every four years by qualified and accredited experts.
Households and small and medium-sized enterprises would be excluded from this requirement.
Exemptions
Large companies which are already implementing an energy or environmental management system that is certified by an independent body according to the relevant European or international standards would be exempted from this requirement, provided the management system includes an energy audit.
