D - 73262 Reichenbach an der Fils: In the Esslingen district of Baden-Württemberg, a new building quarter is being constructed with a so-called "cold local heating network", which will not only heat the 41 houses in an environmentally friendly way in the future, but also contribute to the temperature control in summer. Photovoltaic systems including storage tanks, which will supply the neighbourhood with home-generated solar power around the clock, round off the energy concept. The focus is on an innovative local heating supply based on geothermal energy. Completion: 2020(?)
The heat transfer medium conducted through the local heating network will have an annual average temperature of only 8 to 10 °C - hence the name "cold local heating network". It is fed via a near-surface geothermal field, which is located about one and a half metres below the earth's surface. "In new development areas with low heat demand, cold local heat offers an efficient, climate-friendly supply due to the low flow temperature in the heating network," Jungkunz explains. The plot for the collector field covers an area of 3,900 m² and can be used for unrestricted agricultural purposes again after it is laid in spring 2019.
The residents will not only benefit from the future-oriented technology in winter. In summer, it enables climate-friendly temperature control of the buildings. The operation of the 41 heat pumps, which provide heating and hot water, also follows this ecological line: operator NATURSTROM supplies them with high-quality green electricity, certified with the Green Electricity Label.
The Ministry for the Environment, Climate and Energy Management of the State of Baden-Württemberg is supporting the project as part of the "Energy-efficient heating networks" funding programme.
The all-round sustainable energy concept is complemented by photovoltaic systems on the roofs of the detached houses and semi-detached houses. In order to be able to use the electricity produced regardless of the weather, it is temporarily stored in battery storage units that can hold up to 9.30 kilowatt hours of clean electricity. The future owners can either purchase the photovoltaic systems including storage as part of the building or alternatively lease them from NATURSTROM.
In addition to the climate-friendly energy supply, EcoShare Solutions and NATURSTROM also have the mobility of the future residents in mind: A photovoltaic carport including an e-charging station and e-car sharing vehicle completes the sustainable energy concept and is intended to promote climate-friendly electric transport in the neighbourhood.
