Project summary
Completed in 2001, this solar housing estate is the first one built in the “Ruhrgebiet”. It is situated on the outskirts of a former coal-mine and spans about four hectare. Built by two different building promoters this settlement is divided into a north and a south sector. The northern part mainly includes basements, massive constructions and inclined roofs in contrast to flat roofs and timber frame constructions in the southern sector. Thus, each house situated in the north sector provides itself with solar heat and electricity whereas the south is centrally organized. Besides a high thermal insulation each unit is equipped with a solar module generating 1,5kWp and 1kWp respectively, which equals a share of 40% of the overall power demand. Due to its early realization this settlement acted as example to encourage further projects. Since measurements were taken within a scientific monitoring the project served as basis to improve further projects.

Urban scale PV aspects
The first housing development in the Ruhr region to fully exploit solar potential was built in the Bismarck quarter of Gelsenkirchen with masonry and woodframe constructed homes. In addition to autonomous, house-by-house energy supplies, energy transfer points at terminal stations are also used for groups of homes. Features of the development * 72 housing units * Annual heating requirements 40 to 60 % below 1995 heat insulation regulation * Solar collection covers 60 - 65 % of hot water demand (470 m² collector surface) * Photovoltaic units cover 40 % of power demand; installed output: 80 kWp * Rainwater percolation

PV architecture and building integration
Urban planning issuesCentrally situated, this settlement has a very good connection to all relevant facilities, schools and to the local public transport. Thus, it helps avoiding individual transport.
