Location
Description
Dresden, one of the four German H2020 Lighthouse Cities, wants to serve as an innovation hub for other cities. It plans to close the energy and material cycles by recovering energy from bio-waste and wastewater, increasing the use of RES, developing guidelines for sustainable construction, and decarbonising the transportation system.
What is special about Dresden is that it will create a PCED with virtual boundaries, consisting of two distinct locations (A, B) that link the two most common building types in Germany and Europe: high-rise apartment complexes (A) and detached multifamily compact buildings (B).
Technologies
Buildings and energy
Local photovoltaic and tenant model – “Mieterstrom”:
Virtual summation of meters.
Tenant model (electricity supply from owner to tenant).
Maximisation of own electricity use through power-heat coupling and storage use.
Heat supply for the district through decentralized heat pumps and near-surface geothermal energy.
Full use of building roofs for PV power production.
Refurbishment solution for existing buildings based on building mass as thermal storage.
Life cycle-optimized new construction solutions.
Optimisation of the entire energy generation system.
Decarbonisation and flexibilisation of district heating:
Decoupling a sub-network to regularly lower the branch temperature.
Legionella prevention through digitalisation of the nodes in combination with hydraulic balancing, filter systems, solar PV solutions, compensation and heating bars.
Implementation of a low-ex-strategy for the entire district heating.
Integration of heat pumps.
Smart and model predictive control of flow and return temperatures in house substations and district heating transfer stations, including monitoring pressure, temperature and volume flows.
Mobility & Transport
Expansion of charging infrastructure.
Pilot bi-directional charging.
Dynamic V2G charging tariffs.
Development of the infrastructure for a sustainable mobility concept.
ICT
Monitoring of building operation, operational optimisation and proof of target achievement.
