In 2020, Halton’s Lahti unit implemented multiple measures to reduce energy consumption and greenhouse gas emissions. In the second half of 2020, the Lahti unit’s heating system was changed from natural gas to geothermal heating, and the factory hall’s ventilation system was renovated to be more energy efficient through more advanced sensing and automation. A new cooling system, which utilizes ground source cooling, was also built in the factory hall. In addition to these changes, the Lahti unit has been using CO2-free wind-generated green electricity since January 2020.
Great results can now be seen after about a year of the measures taken. According to the forecast, energy consumption will decrease by about 25% this year compared to 2020, when the geothermal system had been in use for part of the year. Compared to 2019, energy consumption will decrease by more than 40%. This also means annual savings of several tens of thousands of euros in energy bills. In 2020, CO2 emissions from energy consumption decreased by 75% compared to 2019. In 2021, the C02 emissions from the energy consumption of Halton’s Lahti unit will be zero.
