In two residential blocks the AIRCONOMY® system provides a round-the-clock pleasant living climate. Installed directly on the concrete slab, AIRCONOMY® has a build height of only 13. 8 cm, naturally including sound insulation, underfloor heating pipe, supply and extract air ducts as well as final screed. In total 35 new residential units were built including 2,560 m² of AIRCONOMY®. With great success! In spring 2013 the second section on more than 2,560 m² was started.
