Can a 30-year-old heating and ventilation system become an energy-saving showcase
project? “Yes, it can – we’ve proven it!” says Michael Schlüter from Kieback&Peter.
Together with his team, he reduced energy consumption in the “Lindenplatz und
Quellenhof” health centre by around 30% – while maintaining full operation and without
any loss of comfort.
