Current energy efficiency issues were discussed in Lahti with a focus on measures with the greatest saving potential

Those interested in energy efficiency gathered on August 21 in the striking scenery of the Lahti Sports Centre to discuss current standpoints on the issue. The event was organised in collaboration by WWF, the LIFE EconomisE project, the city of Lahti, Kiinteistöliitto Päijät-Häme and Lahti Region Development LADEC Ltd.

The event began with three interesting presentations on energy efficiency. The first speaker was Lari Paavolainen, Sales Manager at Leasegreen Ltd, whose presentation mentioned, for example, housing company renovation measures which will pay for themselves. According to Paavolainen, these include heat production, ventilation, solar panels, smart heating control, LED lights, saving water and heat recovery from waste water.


The Property Manager of Lahden Tilakeskus Jouni Arola explained that energy efficiency has become part of the city’s normal operation in investment and maintenance projects. According to Arola, more efficient use of space is the energy efficiency measure that has the biggest energy saving potential and the biggest impact on overall consumption. After Arola, the entrepreneur Paul Stucki from Orfer Oy, which specialises in robot technology, shared his experiences on the impact of a ground heat system on energy consumption.
