Perfect Climate for the Greenhouse: MEVO AIR in Piemonte
Indoor greenhouse reference, designed for multilevel aeroponic crops.
In vertical farming, all environmental parameters are crucial. Temperature, humidity, ventilation, and CO₂ all directly affect crop quality and yield. Precision is essential.
For this reason, we tested the MEVO AIR system—the GSI-branded heat pump designed to precisely manage the indoor climate—in a brand-new Vertical Farm in Piemonte.
Here are the results of the monitoring conducted during the summer season.
Spoiler alert: They exceeded expectations.
A facility designed to grow better crops
The indoor greenhouse we analyzed, designed for multilevel aeroponic crops, is an enclosed, advanced climate-controlled environment with a volume of about 520 m3. Any slight overhang can compromise plant growth or increase operating costs.
That is why we proposed MEVO AIR, a system capable of managing:
- Heating and cooling
- Humidity control
- Continuous and targeted ventilation
- Potential integration with active CO₂
The goal was simple but ambitious: to maintain a stable, efficient, and sustainable microclimate.
Temperature: stable, precise, ideal
During the monitoring period, the indoor temperature remained perfectly within the optimal range of 20-26°C, with an average of 22.2°C.
The most surprising thing? The standard deviation was only 0.85°C.
In practice, the environment remained constant and was protected from temperature changes, creating the perfect conditions for healthy and continuous growth. And in vertical farming, thermal stability is gold.
Humidity: under control and smart
Humidity levels were also well maintained. It averaged 69.7%, ranging from 64% to 73%.
The strength? Dehumidification is dynamic: it adapts according to actual conditions. The system extracted an average of 5.9 liters/hour of moisture, with peaks of up to 10.1 l/h, but is also able to stop when not needed. This means zero waste and perfect control of plant transpiration.
Ventilation: constant and well distributed.
The MEVO AIR maintained a constant airflow rate at 2657 m³/h, with minimal variation. This allowed a uniform distribution of temperature, humidity, and CO₂ (when present).
Uniform ventilation prevents microclimates, reduces disease risks, and ensures identical conditions for all plants, regardless of their location in the greenhouse.
Electricity consumption: smart and adaptive
One of the most valuable data points concerns energy consumption. The average consumption was 1.29 kW/h, with automatic modulation according to need.
In other words: the system does not always operate at maximum capacity but rather only when necessary. This allowed us to maintain an average daily consumption of about 31 kWh, which is optimal for a facility of this size.
The result? Lower operating costs and reduced mechanical stress on the system.
In summary: here’s what works
After data collection, we can confirm that MEVO AIR achieved its goal. Here is a brief recap:
🔹 Strengths:
- Stable and precise temperature
- Humidity under dynamic control
- Uniform ventilation
- Low and efficient consumption
🔹 Next steps:
To further optimize our client’s facility, we suggested two strategic actions:
- Targeted CO₂ enrichment:
Crop-specific targets. - Setpoints optimization:
Advanced analysis of heat pump modulation to anticipate plant needs at each stage.
Conclusion: a solid foundation, an even more efficient future
Thanks to MEVO AIR, the facility is now a solid, high-performing Vertical Farm, ready for evolution. With just a few strategic interventions, it can become a benchmark in the industry.
If you work with controlled-environment facilities or are designing your own indoor greenhouse, this experience may prove useful.
