When we made the plan for 4GDH, more than half the housing stock was about to be energy refurbished. But, in 2025 the majority of the homes will be ready for LTDH.
Now, we have to decide how to continue: One possibility is two parallel DH systems:
1. A 3GDH for the non-refurbished houses, 2. and a 4GDH for the new houses and the refurbished houses.
We will focus on the privately-owned houses developing energy refurbishment concepts with the local housing organizations – and offering house owners free energy consulting. If we can improve "the rest," we can reach 100% LTDH.
