Développement Urbain Masterplan, Freiberg a. N., Allemagne
Public buildings in the centre, such as the townhall, event centre and school, as well as commercial buildings and apartments, are already being supplied with local heat from the municipal combined heat and power units in combination with peak load gas boilers.
As part of the redesign of the city centre, it is also planned to connect the new Oscar Paret School, the new sports hall and other future buildings to the existing local heating supply and to redesign the energy generation system in order to operate it in the long term in a climate-friendly manner. The goal is to minimize the consumption of non-renewable energy. This is to be achieved by using a large-scale solar thermal system on the roof of the Oscar Paret School and the sports hall in combination with long-term heat storage and a heat pump. These components are supplemented by combined heat and power plants which, in addition to generate heat and also feed the city's own power grid. Gas boilers cover peak loads in winter by additionally supporting heat generation.
By energy-efficient new buildings and energetic reorganization of the inventory a reduction of the entire energy need is possible despite an increase of the used surfaces.
