What must a Frankfurt data centre report about waste heat reuse?
Under the EU Energy Efficiency Directive, data centres with installed IT power of 500 kW or more report key indicators every year to a European database, including energy use and how much waste heat is reused. The delegated act sets the indicators, such as the energy reuse factor.
Who reports
Article 12 of Directive (EU) 2023/1791 covers data centres with an installed IT power demand of at least 500 kW. Delegated Regulation (EU) 2024/1364 sets what they report and how.
What is reported
- Total energy consumption and IT energy, giving PUE.
- Renewable energy share.
- Waste heat reused, as an energy reuse factor.
- Water use, as WUE.
National rules
Member states can add their own requirements on top. Check German law for any reuse targets that apply to your site.
What Senseible does here
Senseible reads each site's monthly electricity bills into a dated Scope 2 record, keeps renewable purchase documents beside them for market-based reporting, and records diesel for backup generators as Scope 1. Customer shares use the allocation key you enter.
