Data centers generate large amounts of heat while processing and storing digital information. That heat must be continuously managed by cooling systems to keep equipment operating within the required conditions.
Under the right circumstances, some of that energy can become a heat source for greenhouse production.
The opportunity sounds straightforward: one facility needs to remove heat while another needs heat. In reality, creating a successful connection depends on the temperature, availability, location and energy requirements of both operations.
Servers contain processors that operate continuously and convert part of the electricity they consume into heat.
A data center therefore needs a cooling strategy to remove that heat and maintain reliable operation.
Depending on the design of the cooling system, the recovered heat can become available at different temperatures. This matters because the higher the usable temperature, the easier it may be to integrate the heat into another application.
For greenhouse production, however, temperature is only the beginning of the assessment.
One attractive characteristic of data centers is that they can operate for long periods with relatively consistent computing activity.
This can create a substantial and potentially predictable source of heat.
At the same time, greenhouse heat demand varies strongly throughout the year. A greenhouse typically needs significantly more heating during colder periods than during warm periods.
A successful project therefore needs to consider both sides:
How much usable heat is available, and when?
versus
How much heat does the greenhouse require, and when?
The closer those profiles match, the greater the potential for productive heat use.
Sometimes, but not always.
The usable temperature depends on the data center cooling concept and its operating conditions. Lower-temperature heat may require additional treatment before it can become suitable for greenhouse production.
The greenhouse concept itself also matters. Technologies designed to make efficient use of lower-temperature heat can broaden the range of energy sources that may be considered.
This is where Ultra-Clima® can be particularly relevant. Its climate concept allows KUBO to explore lower-temperature energy sources that can be more difficult to use effectively in conventional greenhouse heating systems.
KUBO's technical material specifically identifies data centers as a potential low-grade heat source for Ultra-Clima®.
There are several key questions.
| Is the heat suitable? | The available temperature and capacity must be compatible with the greenhouse energy requirements. |
| Is enough heat available at the right time? | Total annual heat production does not tell the whole story. The timing and consistency of supply must also match the greenhouse demand. |
| Are the facilities close enough? | Distance matters. Connecting two facilities requires infrastructure, and longer distances can affect both project costs and overall energy efficiency. |
| How reliable is the energy source? |
Maintenance, changes in data center operation and the cooling strategy can influence how much recoverable heat is available. |
A greenhouse production system cannot simply assume that an external source will always deliver exactly the required amount of heat.
Does the business model work for both parties?
The heat may be a by-product for the data center, but transferring it to another facility still requires infrastructure and long-term agreements.
Heat pricing, availability, required offtake and operational responsibilities can all influence project feasibility.
That is why KUBO looks beyond the technical connection and evaluates the relationship between the energy source and the greenhouse as part of the complete project.
For greenhouse projects, data center heat can create access to an alternative local energy source.
Depending on the project, this can contribute to: reducing dependence on conventional energy sources; creating a more diversified energy strategy; lowering the carbon intensity associated with greenhouse heating; supporting long-term sustainability objectives.
These benefits are project-specific. The actual environmental and commercial performance depends on the complete energy system rather than on the heat source alone.
A greenhouse can provide a productive destination for heat that forms part of the data center's cooling process.
This can support broader ambitions around energy efficiency, heat reuse and sustainability.
For some projects, productive heat use may also become relevant to planning, permitting or ESG objectives.
However, heat reuse should not automatically be presented as proof of improved data center efficiency. Its actual impact depends on the cooling technology, infrastructure and operating strategy.
For KUBO, the focus is therefore not on making broad claims, but on designing a combination that creates practical value for both facilities.
One example is the FIO project in Canada, where a greenhouse project is being developed in connection with heat from a data center.
The project illustrates the broader opportunity: combining digital infrastructure and controlled-environment food production through a shared energy concept.
Could a greenhouse become part of your data center energy strategy?
The presence of waste heat alone does not determine whether a project will work.
The opportunity depends on the interaction between heat availability, greenhouse demand, location, infrastructure, reliability and commercial conditions.
KUBO brings those elements together to assess whether greenhouse production can become a productive destination for available data center heat.
