In 2025, a heat pump using a 200-metre-deep well was put into operation. This makes both heating in winter and cooling in spring, possible, while also making optimal use of unused solar energy.
In addition, two ULO cells were put into use for the biological control of mites. Double screens with dehumidification systems were installed to retain heat more efficiently. Soil moisture sensors and digital rain gauges were also installed across all fields to improve water efficiency.
