How we reduce our environmental footprint

Viessmann Sustainability - Renewable energy

We set ourselves the goal of reducing energy consumption in our production site every year. At the same time, we aim at higher energy productivity to leave the smallest CO2 footprint possible on our planet. As part of our integrated management system certified according to ISO 50 001 we have an energy management system in place and regularly observe the consumption data and provide transparent descriptions. 

Energy sources we use

  • 100% green electricity (Green electricity derives from renewable energy sources)
  • 40% of our total energy consumption in our factory in Hof (Germany) purchased by renewable energies
  • Photovoltaic systems on factory roofs where possible
  • Purchase of local heat from bios gas plant next to factory in Hof

How we invest and modernise to act more energy efficient

We continuously check which potential for improvement can be used in our ongoing production. Relevant parameters for this are energy consumption, electricty use, water consumption and the share of renewable energies

Savings for the environment during the recent years

  • New compressors
  • New powder coating machine with 18% less energy consumption, more than 14t less powder needed, better quality
  • New laser system
  • New painting line
  • Camera technology for reducing compressed air consumption
  • Expansion of the photovoltaic system
  • Lighting replacement
  • Retrofitting lighting with motion sensors where possible
  • Installation of dark radiators
