Claims, one by one

The text below is copied verbatim from the published record. Each claim names the source dossiers that carry it; caveats stay attached to the claim they qualify.

Claim 1 clm-ac673c56a1a19d4b descriptive
HOFOR and Danfoss use AI-based predictive control (Leanheat) to shift heat demand in Copenhagen buildings
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this file
What the mapping says
The DBDH trade article names all three actors and the mechanism: "HOFOR (district heating utility), Copenhagen City Properties & Procurement (Municipality's building department), and Danfoss are currently testing the potential of minimizing peak heating demand", and describes the control layer as "Leanheat's AI learns how the building's thermal mass reacts to ambient conditions and evaluates the flexibility potential based on the forecasted weather and set comfort requirements". Demand shifting is stated as "charging and discharging the thermal energy in the building mass". The Danfoss press release confirms the corporate partnership and calls the product a solution that "combines cutting-edge technology, data analytics, and artificial intelligence to optimize energy consumption".
Caveat
The Danfoss release describes the software only as combining data analytics and artificial intelligence; the words "predictive control" come from the DBDH sources, not from Danfoss.

Claim 2 clm-1daae3fc3ba24f4f quantitative
A 2021/22 pilot on 17 municipal buildings
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this file
What the mapping says
Verbatim: "The first part of the demonstration took place during the heating season 2021/2022 and included 17 municipal buildings (mainly daycare centers)." Both the season and the building count match the entry exactly.
Caveat
The source calls it the first part of a demonstration rather than a pilot, and specifies the buildings were mainly daycare centres.

Claim 3 clm-875a45574140f43f quantitative
cut the maximum peak load up to 22%, and the morning peak by 14%
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this file
What the mapping says
The source reports two distinct reduction figures for the pilot: "the average morning peak decreased by 14%, compared with the average peak consumption before the implementation of the smart control" and "The maximum peak power has decreased from 27.5 kW/building to 21.5 kW/building (-22%)." The 22% is the second of these. The source states the basis of the comparison: "The calculation compares the highest peak during load shifting to the highest measured peak in the previous heating season at the same outdoor conditions." It also labels these "the initial results of the demonstrations for the cluster of 17 buildings".
Caveat
The 22% belongs to maximum peak power (27.5 to 21.5 kW per building), the 14% to the average morning peak. Both are first-season results reported by Danfoss engineers, the software's vendor.

Claim 4 clm-0f43a98dc3bfcbd3 quantitative
A proof-of-concept announced in 2023
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this file
What the mapping says
The press release is dated 20 November 2023 and states: "This first project is scheduled to commence during the heating season 2023/24 and run until 2026." It sets the scope as reaching "up to 700 buildings within HOFOR's network".
Caveat
The release announces a project scheduled to commence in the 2023/24 heating season; it does not report a rollout already under way in 2023, and its stated target is up to 700 buildings, not the 140 the entry reports.

Claim 5 clm-8c4e19c8d3cc5c39 quantitative
now covers 140 buildings from 20 owners
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this file
What the mapping says
Verbatim: "So far, the project has proven quite successful, being able to activate up to around 8 MW of flexibility through voluntary agreements with 20 large building owners and 140 buildings." Both counts match the entry.
Caveat
This 2025 article describes HOFOR's flexumer proof-of-concept; neither it nor the Danfoss release states that this is the same project the 2023 release announced.

Claim 6 clm-c8b1fee4ae8bf46b quantitative
activating about 8 MW of flexible capacity
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this file
What the mapping says
Verbatim: "being able to activate up to around 8 MW of flexibility through voluntary agreements". The article adds that the system benefits are to be tested "during the heating season of 2025/2026".
Caveat
The source says up to around 8 MW can be activated — a ceiling of available flexibility, not a measured average of capacity actually dispatched.

Claim 7 clm-272b7bbb3caabeeb quantitative
averaging 5% energy savings
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this file
What the mapping says
The 2025 trade article reports a realised figure: "they have, on average, realized a 5 % energy savings since the beginning of 2025 by accessing an online predictive control system for their district heating substations, utilizing weather forecasts as part of the POC." The 2023 Danfoss release had forecast the same number in advance, as "anticipated savings of an average of 5 %".
Caveat
Both figures are the operators' own reporting; no independent evaluation is cited. The Danfoss number is an expectation stated before the project began, the DBDH number a self-reported result covering only 2025.

2021/22 pilot cut the maximum peak heat load up to 22%
Published field
impact · verbatim
Mapping
mapped · no interpretation or interpolation added by this file
What the mapping says
The source dates the demonstration to "the heating season 2021/2022" and reports "The maximum peak power has decreased from 27.5 kW/building to 21.5 kW/building (-22%)", alongside a separate figure that "the average morning peak decreased by 14%". The source states the basis of the comparison: "The calculation compares the highest peak during load shifting to the highest measured peak in the previous heating season at the same outdoor conditions." It also labels these "the initial results of the demonstrations for the cluster of 17 buildings".
Caveat
A first-season result, written up by Danfoss engineers — the vendor of the control software — in a trade journal; no independent evaluation is cited.

Mapping
mapped · no interpretation or interpolation added by this file
What the mapping says
Danfoss announced the HOFOR partnership on 20 November 2023, stating that "This first project is scheduled to commence during the heating season 2023/24 and run until 2026" and would reach "up to 700 buildings within HOFOR's network".
Caveat
2023 is the year of the announcement; the release schedules the start for the 2023/24 heating season and names a target of up to 700 buildings.

Claim 11 clm-1efa0f1e06909adf quantitative
covers 140 buildings/20 owners as reported in October 2025
Published field
impact · verbatim
Mapping
mapped · no interpretation or interpolation added by this file
What the mapping says
The article, published 21/10/2025, states: "So far, the project has proven quite successful, being able to activate up to around 8 MW of flexibility through voluntary agreements with 20 large building owners and 140 buildings."
Caveat
October 2025 is the article's publication date, not an as-of date stated in the text; the article says only "so far". It also describes the arrangement as a proof-of-concept, with system benefits still to be tested in the 2025/2026 heating season.

Claim 13 clm-8b1386632baf03e6 quantitative
averaging 5% energy savings

impact · verbatim
Mapping
mapped · no interpretation or interpolation added by this file
What the mapping says
Verbatim from the 2025 article: "they have, on average, realized a 5 % energy savings since the beginning of 2025 by accessing an online predictive control system for their district heating substations, utilizing weather forecasts as part of the POC." The 2023 Danfoss release names the same figure prospectively: "anticipated savings of an average of 5 %".
Caveat
Operator-reported in both cases, with no independent evaluation cited; the DBDH figure covers only the period since the beginning of 2025, and the Danfoss figure is an expectation stated before the project started.
