Combination of innovative technologies provides energy extraction Koppert Cress, The Netherlands About Efficiency and sustainability form the foundation of every greenhouse concept Certhon delivers. For Koppert Cress, in addition to the previously completed main location at Poel 1 and the second site at Poel 8, we developed an advanced greenhouse at Poel 18 where energy is intelligently harvested, stored, and reused. By integrally designing technologies such as aquathermal energy, thermal energy storage (ATES), heat pumps, and advanced climate systems across all three locations, a single robust energy system was created that performs optimally in every season. Summer heat is efficiently reused for winter heating, resulting in lower energy costs and a significantly reduced environmental footprint. This project demonstrates how thoughtful system integration makes fossil-free cultivation possible—without compromising crop quality, reliability, or operational continuity.

We think alongside our clients and look ahead. The projects delivered for Koppert Cress—including the integrations realized across all their locations—result in a series of remarkable highlights: Collaboration as a driver of innovation The realization of this project was a multidisciplinary effort involving Koppert Cress, Division Q, and various technical partners. Certhon acted as system integrator, ensuring seamless alignment between construction, installations, and climate strategy. By coordinating all disciplines from the design phase onward, a robust greenhouse concept emerged, which is fully prepared for further sustainability advancements. ErfGoed Airflow floor as a foundation The integrated ErfGoed Airflow floor is a key element of the climate concept. This system combines heating, dehumidification, and air movement in a single solution, creating a uniform climate at crop level. Certhon integrated the floor both structurally and technically into the greenhouse design, resulting in an energy-efficient system without traditional air distribution or noise-intensive installations. Integrated energy system Natural heat from surface water is harvested through aquathermal energy and stored in an underground thermal energy storage system (ATES). Combined with heat pumps and a smartly designed thermal infrastructure, this energy can be deployed at the right time. Excess summer heat is reused in winter, reducing energy costs and minimizing dependence on fossil fuels. Controlled and uniform climate with JSK The JSK system ensures a stable and controllable greenhouse climate. With individual unit control and integrated heat exchangers, it seamlessly connects to the overall energy and climate concept. This provides Koppert Cress with maximum control over temperature and air movement, fully tailored to crop requirements. Future-proof design The greenhouse is prepared for the next steps toward fully fossil-free cultivation. The design can accommodate low-grade heat from geothermal sources and is ready for future CO₂ capture from ambient air. In addition, solar panels are integrated into the greenhouse roof for optimal energy generation. All elements come together in one technically reliable and scalable greenhouse concept.
