Editor's Notes
- #17: Von Beginn der Planung an war es das erklärte Ziel des Bauherrn das Eigenheim als zukunftsfähiges Gebäudekonzept zu errichten, sich von Energiepreisentwicklungen frei zu machen und somit einen dauerhaften Immobilienwert zu schaffen. Wir waren erst bei der Erstellung der Monitoringkonzeption und dem Monitoring selbst beteiligt.
- #18: Eckgrundstück Von Bäumen umgeben Süd-West / Nord Ost orientiert
- #19: 2 ½ Geschosse Ausgebautes Kellergeschoss Satteldach mit einer integrierten PV-Anlage auf dem Süd-West Dach
- #20: Architektonisch charakteristisch ist die durchgesteckte einläufige Treppe, die alle Geschosse miteinander verbindet.
- #26: Bezogen auf 358m² Bruttogrundfläche und 4 Personen im Gebäude
