At its headquarters in Schkölen, Germany, the NESTRO Lufttechnik GmbH generates her own electricity already since 2013. More than 2000 polycrystalline PV-modules - mounted on the flat roof and partly on the facade - represent a capacity of nearly 500 kWp. The electrical power generated by these solar modules is used to primarily operate the machinery on site. Overcapacities are fed into the public electric supply network.
Also at the premises of NESTRO Hungária Kft. in Pécs, Hungary, electricity is been generated. More than 100 polycrystalline modules stand for a capacity of about 30 kWp.

An internally developed heating system combusting environmentally sustainable material (straw) covers the heat demand in Schkölen since 2006. The system is complex. The downstream components include a.o. a straw shredder, the special boiler and a flue gas filter. In total, the system has a heating power of 500 kW. On a regularly basis emission values are monitored and fall short of the legal upper limits given.
NESTRO PPHU Sp. z o.o. in Olesno, Poland, use an innovative heat pump to heat and chill both office and factory buildings on a total area of 640 m². This modern equipment saves up to 75% of energy compared to other heating systems.
A woodchip boiler heats the office, the work hall and the warehouse in Pécs on a total area of 2000 m². The woodchips are shredded rest materials (packaging, broken palettes and plywood panels).
