BAFA reporting deadline: 347 days remaining (March 31, 2027)
EnEfG Compliance

BAFA waste heat assessment. 15 minutes instead of 3 weeks.

The annual reporting obligation under EnEfG §§ 13, 17 is due March 31, 2027. Ardor produces a BAFA-compliant PDF report for €299 per site, using the same methodology energy consultants charge €15,000 to €30,000 to apply.

Based on EnEfG §§ 12–17 and BAFA guidelines

02

Calculate heat profile

Automated waste heat calculation, temperature profile and peer benchmarking. Proximity analysis included.

03

Receive report

BAFA-compliant PDF with calculation methodology, source citations and sign-ready operator declaration.

Contents of the report

10 sections, compliant with the requirements of EnEfG §§ 12–17 and BAFA reporting guidelines.

01Executive Summary
02Facility description and installed capacity
03Waste heat volume calculation with methodology
04Temperature profile and availability
05Regulatory status (EnEfG compliance)

10Operator declaration (sign-ready)

Regulatory basis

The German Energy Efficiency Act (EnEfG) requires operators of data centres with 300 kW or more IT capacity to annually document their waste heat potential.

For comparison: energy consultants typically charge €15,000 to €30,000 for an equivalent first assessment. Follow-up years: €8,000 to €15,000. Ardor delivers the report in full, or you receive a refund.

The platform behind the report

The compliance report is the entry point. Every assessment adds a verified heat profile to the Ardor database. From this database, the European heat marketplace will emerge.

Layer 01

Heat Map

Geospatial visualisation: data centres, district heating networks, potential offtakers across Europe.

In development
Layer 02

Feasibility Calculator

Automated assessment: waste heat volume, temperature profile, distance to nearest network, CAPEX estimate.

In development
Layer 03

Compliance Report

BAFA-compliant PDF report with calculation methodology, proximity analysis and operator declaration.

Available
Layer 04

Heat Marketplace

Data centres post heat profiles. Offtakers search and filter by proximity, temperature, volume.

2027

Every compliance report adds a verified heat profile to the database. The database is the strategic asset. The more reports, the more valuable the marketplace.

What we're building

Ardor makes waste heat compliance for data centres effortless. We automate the assessment that EnEfG requires and deliver a report that can be submitted directly to BAFA.

Our calculation methodology is based on the thermodynamic principle that nearly all electrical energy consumed by a data centre is converted to heat. Calibrated with industry data from Bitkom, AGFW and the Uptime Institute.
