More liveable space for more residents
The Free and Hanseatic City of Hamburg is the second largest city in Germany, with its 1.8 million inhabitants in the city adding up to 5 million inhabitants in its metropolitan region. Hamburg is a city as well as one of the 16 federal German states. Economically and culturally, Hamburg is the centre of Northern Germany and one of Europe’s most liveable and economically strongest cities. This is why Hamburg is undertaking great efforts to put its Smart City approach into reality by using smart technologies and implementing numerous interdisciplinary pilot projects.
And Hamburg is still facing a growth trend… Especially younger people are attracted be the city’s dynamic economy and the large number of jobs, by the variety of educational institutions and the large range of leisure facilities and cultural opportunities. The aim of the current town planning is to find spaces within the existing areas as well as opening up new development opportunities. The city wants to create additional, high-quality urban spaces by the water, offering homes, jobs, leisure and recreation.
The mySMARTLife demonstration area, the borough of Bergedorf, is Hamburg´s biggest district, located in the East of the city. The district is diverse, with a historic centre with numerous heritage-listed houses as well as residential buildings. All are subject of an integrated strategy targeting the quality of life, citizen involvement, technical and social infrastructures, public buildings and spaces.
There are three zones of interventions, where the 59 mySMARTLife actions in Hamburg will be implemented:
- Zone 1 comprises the new construction area “Schleusengraben”, where more than 1,400 new residential units will be built. They will be above national energy efficiency standards, with smart controls and connection to an innovative low-energy district heating mainly based on renewable energy sources. Also, new smart adaptive lighting for bicycle routes will be implemented.
- Zone 2 “Bergedorf-Süd” is the name of an ambitious retrofitting area, where an innovative concept of independent Smart Heating Islands will become reality, again mainly based on renewable energy sources. Also, a humble lamppost initiative is foreseen to replace the existing street lamps.
- Although the mobility interventions affect the whole City of Hamburg, they are a focused activity in Zone 3, comprising the entire borough of Bergedorf. Here, electric buses, e-cars, e-bikes and the “Cityskater” (a small last mile e-scooter) for public and private fleets are implemented as well as e-bus charging stations at the bus depot, several fast charging stations and a set of private and public stations for e-cars, all supplied with energy stemming to 100% from renewable energy sources. A multi-modal mobility concept and innovative approaches like a car sharing e-community and parcel delivery system in car trunks complement the actions in Zone 3.
The new construction area "Schleusengraben" is a focus development area of the City of Hamburg, along the shores of an old industrial channel. The general development of the "Schleusengraben" is divided into six different areas - each area with its own investor and its own architectural and energy supply concept. This is a typical setting in which urban development takes place in Hamburg. Basis for the development of the different areas are urban development contracts between the investors and the administration of the Borough of Bergedorf.
As part of mySMARTLife, the Borough of Bergedorf tries to convince investors to build above national standard, incorporating smart metering and smart controls. This is being done through a process of face-to-face conversations, workshops and the demonstration of best practice examples.
More than 1,400 new residential units are planned to be built in the next years (approximately 75 buildings) including the implementation of a new smart adaptive lighting.
The retrofitting area "Bergedorf-Süd" is a town quarter with a wide mix of old buildings (approximately 500) partially with Wilhelminian architecture and a highly diversified homeownership. As part of mySMARTLife, the borough proactively approaches the homeowners in order to motivate and advise them on energetic refurbishment. The aim is to implement the concept of “smart heating islands”, which describes heating networks on house block scale mainly based on renewables.
Also smart controls, domotics and smart meters will be installed. A humble lamppost initiative is foreseen to repurpose existing lamps, along a newly planned bicycle street.
Public transport is to be playing an important role in Bergedorf’s modal split, thus it needs to be further developed in a sustainable manner. The bus lines serve the central part of the high-performance district. Five 12-meter and other five 18-meter articulated buses will be deployed in Hamburg-Bergedorf. With the aim to equip the bus depot of the public transportation company VHH with charging infrastructure for 10 e-buses, major changes to the main power supply became necessary. With regards to future developments, the local depot grid will be re-dimensioned completely to allow successive installation of charging infrastructure up to a fully electrified depot by 2030.
Regarding charging infrastructure, the City of Hamburg has rolled out more than 600 charging points in the whole area of Hamburg, thereof 22 in the Borough of Bergedorf and 11 in the project area. mySMARTLife in Hamburg is focused on the installation of charging infrastructure for intermodal concepts, i.e. mobility hubs combining mobility services such as car sharing, bicycles etc.
In connection with the rapidly increasing number of electric vehicles and the simultaneous increase of charging points, site-related grid connection capacities will become more and more important. An electrification of (public) fleets often is faced with inefficient grid capacities. The necessary expansion is usually cost intensive. This can be remedied by an intelligent charging technology, a so-called intelligent load management, which will be developed in the context of the project. Furthermore, the Hamburg University of Applied Sciences will build a clean energy charging station, providing 100% of green energy for e-cars and e-bikes.
The public authority vehicle fleet of the Borough of Bergedorf will be renewed and electrified. Micromobility solutions will be adopted through the introduction of e-bikes and last mile people movers. A community car sharing concept will be introduced and implemented in the project area in cooperation with a housing company.
The City of Hamburg Urban Platform will be supplemented with the DTAG (T-Systems, AG) Smart City Ecosystem to form a “System of Systems” following the DIN Spec 91357 on “Open Urban Platforms”. New services will be developed and a new kind of web service for real-time sensor information will be introduced and approved. The aim is to improve the standardised connectivity in order to allocate (open data) apps and services to authorities, citizens and stakeholders. Digitisation leads to new service opportunities and data generation, which will be aligned, harmonised and managed in the Hamburg Urban Platform.
The following vertical smart city applications will be connected to the smart middleware of the Deutsche Telekom’s Smart City Ecosystem: smart street lighting, intermodal routing and smart grid. Further investigation is planned concerning interoperability of two combined "platforms" (forming the Hamburg Open Urban Platform) and other Smart City Platforms, e.g. to the partner Lighthouse Cities Nantes and Helsinki.
