Local heat as far as the eye can see: the IBA project “Global Neighbourhood” is the first to benefit from the environmentally friendly heat produced locally. Step by step, the heating grid will be expanded outwards from the bunker by 2015 and will supply 3,000 homes and other heat consumers in the northern Reiherstieg neighbourhood.
It's a heating grid of short distances as the Energy Bunker sits at the centre of the supply area. The short paths and low grid temperatures compared to district heating reduce heat loss and transmission costs. The Energy Bunker is a role model for future heat supply development.
The ‘Renewable Wilhelmsburg’ climate protection concept envisions supplying the district with 100% renewable energy by 2050. One fundamental component of the plan is the three local heating grids, the Energy Bunker (northern Reiherstieg neighbourhood), deep-mined geothermal energy in Wilhelmsburg (south of there, including parts of the industrial and commercial zone in the west of Wilhelmsburg) and Central Wilhelmsburg Energy Cluster.
The Energy Bunker at the centre of a local heating grid is a particularly good example of the potential of a decentralised heat supply system employing specific local energy sources.
