 ===== The "Nulli" in Dörpe =====
-{{:picopen:nulli_in_doerpe.jpg?300 }} <- ** The "Zero-energy house"(("Null" means "0" zero in German. The buildings was intended to consume no heating energy at all.)) in Dörpe near Hannover.**\\ \\ The "zero-energy house" by Erhard Wiers-Keiser and the organisation for "Ecological Future Workshop for Minimum-energy and Zero-energy Houses e.V."  (1989) was calculated as having smaller demand values than a Passive House, but unfortunately the consumption values during operation were higher.  Problems were due to reduced airtightness (non-reinforced building board), the insulation shutters on the inside and the solar storage technology. The annual 10 m³ solar storage was later removed to make space for a new wing, but the house was still used as an "almost Passive House" as before. Robert Borsch Laaks contributed significantly to the details. See [[Basics:The Passive House - historical review#Literature|[Hinz 1994] ]].
