Description
Expected Outcome:
Project results are expected to contribute to all of the following expected outcomes:
• Improved open access to performance data, sharing of best-practices and useful knowledge and information for owners and operators of IT infrastructure, as well as the IT and building sectors;
• New designs of IT rooms in buildings or small edge data centres valorise waste heat through thermal management techniques, processes and tools.
Scope:
The growing energy needs of the ICT sector must be met while aligning with climate neutrality and sustainability goals. Small IT rooms or small data centres are an essential part of the twin green and digital transition. It is important to address the energy and resources consumption over the full ICT value chain. Solutions already exist, such as re-using waste heat from data centres, or moving towards circular models (longer lifetimes, reparability, reuse and recyclability). Most recent analysis suggests that the energy consumption of consumer devices in 2020 accounted for roughly 50% of the overall energy consumption of ICT technologies, with the two next largest contributors being respectively the production of ICT devices (~20%) and the operation of data centres (~15%)[1]. Moreover, this is expected to change dramatically by 2030, as the overall energy consumption of ICT technologies is expected to increase by 50% over this decade. The Commission has set the strategic goal of ensuring that data centres are climate-neutral, energy- and resource efficient by 2030. However, most efforts are directed towards data centres in scope of the Energy Efficiency Directive recast.
Proposals should address all of the following:
• Demonstrate state-of-the-art holistic and cost-effective approaches to thermal management and excess heat recovery (optionally including heat storage and/or upgrade of heat) and re-use in local or nearby site creating effective added value in existing IT rooms in buildings or small edge data centres (in the range of 100-500kW, not covered by Energy Efficiency Directive recast), taking into account thermal envelope/building (by means of simulation or digital twins, among others), integration with building automation and control systems and potential to improve the self-assessment and self-optimisation functionalities at all levels, and integration into existing BMS allowing for further development of energy services. Demonstrators should be located in both cold and warm climate Member State or Associated Country to tackle climate specific challenges of thermal management of waste heat.
• Develop business cases for state-of-the-art solutions for excess heat recovery & re-use (optionally including heat storage and/or upgrade), for example by re-using excess heat in an existing system in the building (such as heating or water production purposes), or in a local district heating and cooling network, or in any other local or nearby site creating effective added value to the recovered heat.
Projects funded under this topic are encouraged to build synergies and leverage their outcomes with funded projects from Cluster 4 HORIZON-CL4-2027-04-DATA-09: Energy efficiency and sustainability of AI data processing in Data Centres (IA) demonstration pilots.

Conditions
Typed facts extracted from the source documents by Scindu's grant-data review. Each value keeps its own conditions. Unknown means unstated, not zero or unlimited.
- Consortium requiredBeneficiaries; affiliated entities do not count toward minimum
- Yes
Unless the topic provides otherwise, at least three independent legal-entity beneficiaries from three different countries: one from a Member State and two others each from different Member States or Associated Countries.
- Other condition
- The Work Programme classifies this exact topic as an Innovation Action.
- Other condition
- General Annex B excludes legal entities established in China from Innovation Actions. The specific Work Programme condition additionally excludes entities established in an eligible country but directly or indirectly controlled by China or by a legal entity established in China only where that topic states the critical-technology restriction.
- Other condition
- Horizon Europe projects must focus exclusively on civil applications.
- Other condition
- If the project uses satellite-based Earth-observation, positioning, navigation and/or related timing data or services, beneficiaries must use Copernicus and/or Galileo/EGNOS; other data and services may also be used.
- Other condition
- Where a Type 2 detailed budget is required, estimates may include subcontracting, purchases, and other cost categories per beneficiary/affiliated entity and work package. Subcontracting must cover action tasks and meet the MGA eligibility and best-value/no-conflict conditions; purchases follow the beneficiary’s usual purchasing practices and best value for money or lowest price, with no conflict of interest. These are estimated-cost rules, not separate LS reimbursement promises.
- Other condition
- The expected outcomes are improved open access to IT-infrastructure performance data and good practice, and new IT-room/edge-data-centre designs that valorise waste heat through thermal-management techniques, processes, and tools.
- Other condition
- The call overview indicates around 3 project(s) expected to be funded under this topic. This is a planning estimate, not a guaranteed award count or consortium-size rule.
- Other condition
- The specific topic conditions state that eligible costs take the form of a lump sum under the Horizon Europe lump-sum decision. This is not direct reimbursement of each actual payroll or invoice.
- Other condition
- The call Work Programme specifies lump-sum funding but does not identify its subtype. For project-based Type 2 lump sums, the Commission’s guidance calls for realistic estimates by cost category, beneficiary/affiliated entity, and work package, using costs eligible under the programme’s actual-cost rules, in line with normal practices, reasonable and necessary for the activities. Confirm the subtype in the call’s submission system before treating that Type 2 estimate table as call-specific.
- Other condition
- Public universities (higher education establishments) established in China and administered by or under the supervision of China’s Ministry of Industry and Information Technology are ineligible to participate in any action under all parts of this Work Programme.
- Other condition
- The granting authority may, up to four years after the action ends, object to transfer of ownership or exclusive licensing of results under the specific Annex 5 provision.
- Other condition
- Approaches should consider the building thermal envelope (including simulation/digital twins), integration with building automation/control and existing BMS, opportunities for self-assessment/self-optimisation and energy services. Demonstrators should be in both cold and warm climates in Member States or Associated Countries.
- Other condition
- Develop business cases for heat recovery and reuse, potentially with storage/upgrade, including reuse in building heating or water production, local district heating/cooling, or another nearby site that creates added value.
- Other condition
- The topic encourages synergy with funded Cluster 4 HORIZON-CL4-2027-04-DATA-09 demonstration pilots; this is encouragement, not a formal participation requirement.
- Other condition
- Demonstrate state-of-the-art, holistic and cost-effective thermal-management and excess-heat-recovery/reuse approaches in existing building IT rooms or small edge data centres in the 100–500 kW range that are outside the recast Energy Efficiency Directive scope. Heat storage or upgrade is optional; recovered heat should create added value locally or nearby.
- Other condition
- The Work Programme expects activity to reach TRL 6–7 by project end. This is an expected range, not a guarantee or a separately imposed funding entitlement.
- Other condition
- The Work Programme allows the responsible Director-General to open the call up to one month before or after its planned opening and to delay its deadline by up to two months. These are call-programme flexibilities, not a claim that a change occurred.
- Other condition
- The Work Programme schedules this call to open 2027-05-05 and sets the deadline as 2027-09-15 at 17:00 Brussels local time.
- Technology readiness level at end, maximum
- 7 TRL
Both endpoints are an expected end-of-project target range, not separate eligibility floors or ceilings. The Work Programme says activities may start at any TRL.
- Technology readiness level at end, minimum
- 6 TRL
Both endpoints are an expected end-of-project target range, not separate eligibility floors or ceilings. The Work Programme says activities may start at any TRL.
Amounts and costs
- Indicative budget
- €15,750,000
Topic budget as stated in the portal's budget table. Lump-sum and per-project limits are in the call conditions.
- Eligible cost limitEligible direct costs in MGA categories A–D, with stated exclusions
- 25 percent of eligible direct costs
The HE MGA flat-rate calculation excludes volunteer costs, subcontracting, financial support to third parties, and exempted specific cost categories. For these topics the grant is a lump sum; this is an underlying estimate/eligibility rule, not a separately reimbursed 25% payment. Operating-grant restrictions may also make indirect costs ineligible under the lump-sum guide.
- Funding intensity, maximumNon-profit legal entity beneficiaries only
- 100 percent of eligible costs per beneficiary
General Annex G permits a rate up to 100% for non-profit Innovation Action beneficiaries. The rate is not an award guarantee and for lump sums is applied through the amount-setting methodology.
- Funding intensity, maximumBeneficiary category under this action type
- 70 percent of eligible costs per beneficiary
General Annex G maximum for this Horizon Europe action type; not an award guarantee. For lump-sum grants, the rate is applied through the amount-setting methodology rather than shown separately in the grant agreement.
- Expected contribution per projectCommission estimated EU contribution for this topic
- €5,250,000
The overview identifies this as an amount around which outcomes could be addressed; different proposal amounts are not precluded. This is not a fixed minimum, maximum, or award guarantee.
- Topic allocationTopic-specific indicative allocation in the 2027 Work Programme call table
- €15,750,000
The Work Programme labels the amount indicative; call footnote says the budget is subject to Union budget appropriations. It is a topic allocation, not a per-beneficiary grant amount.
Personnel and services
