Innovative, sustainable and liveable: building a new model of smart city
Innovative, sustainable and liveable: building a new model of smart cityA glimpse on the MAtchUP case studies
To become smart, a city must use services, tools and technologies tailored to the needs of residents and businesses, and to their urban environment.
A mix of innovative technology-driven solutions and non-tech actions will make our cities more efficient and attractive.

Why MAtchUP?
MAtchUP’s solutions turn urban problems into smart opportunities able to improve people’s quality of life and boost the local economy.
Ultimately, the project creates a more liveable environment for urban communities.

Focus on Dresden: the Johannstadt district
Johannstadt is a densely built inner city district. 25,000 inhabitants on 3.51 km2 means a high density of about 7,200 inhabitants per km2 in this multicultural district.
After World War II, most of the area laid in ruin. It was then rebuilt mostly with socialist architecture during the 1960s and 70s. The area is a focus of city development by the municipality, many refurbishments have been started but some larger unrefurbished houses still remain.
To address this and to ride on the city's innovation wave, Johannstadt has seen its old buildings retrofitted and new smart ones constructed. Situated between the nearby river Elbe and the Dresdens central park the Large Garden and generally many green spaces, the district is now a nice place to live.

SOLUTIONS IMPLEMENTED1. Introducing a tenant electricity model at Blasewitzer Str33 kWp photovoltaic system on existing buildings
A photovoltaic system of 33 kWp was installed on the existing buildings, in collaboration with SachsenEnergie AG.
The balance sheet shows 100% of the energy from PV provided is used in the building itself. Tenants are informed about consumption and RES-production via a display.

SOLUTIONS IMPLEMENTED2. District future houseA housing cooperative with 15 apartments
The District Future House is a smart building managed by hierarchic management systems – one for the entire building and one for each flat. Its thermal demand is covered by district heating while PV panels provide up to 75% of the building's electricity demand with the help of a local storage battery.
Apartment manager
This is the central information and communication platform for tenants. They can choose ventilation, temperatures and times and monitor the consumption of the flat directly on the display.
- Each apartment is integrated into a smart metering concept to visualise energy flows.
- The PV system generates green energy and displays time slots to control electric consumers.
Building energy manager
This optimises the heat & electricity supply and acts as a control panel by transmitting the demand and weather information to the individual managers in the flats.
Tenant electricity model
- The PV system and a battery storage are connected and enable tenants to benefit from the local generation of renewable energy. To inform tenants about their energy efficiency, an intelligent metering system has been installed in the buildings and enables automatised digital billing processes of the housing company.
- Because of the smart building approach of the District Future House, tenants are the first in Dresden who are actively using a flexible tariff with different prices derived from time and Renewable Energy Sources (RES) production on their rooftop.
Energy partnerships for sustainable smart cities
The vertical relationship between energy utilities and their customers is giving way to partnership and innovation, as citizens take an increasingly prominent role in the leadership of the energy transition
We on site
Smart energy for smart cities: We have been offering the tenants of the future house in Dresden's Johannstadt since the summer so-called load-flexible tariffs.
SOLUTIONS IMPLEMENTED3. Pilot Building of the building control centreIn the district alone, 12 public buildings are connected to the control centre and more buildings will follow.
The elementary school – Johanna – was selected as a pilot building to introduce a novel energy management. The building was remodelled virtually. And with the help of software, various modes of heating regulation were tested.
Also, energy management was implemented. It adapts the building heating to the internal and external climatic conditions. The results show a large reduction in energy consumption which gives the solution a high replicability potential for similar buildings.

SOLUTIONS IMPLEMENTED4. E-Cars for the housing sector
The housing sector employs different technical and non-technical staff. Staff usually travel to and from work in urban areas, as headquarters and service centres are located very close to the apartment buildings. The project provided 3 new electric cars for housing companies. Needs are monitored and use cases for housing companies were developed and trialled. This serves as a starting point for the electrification of the car fleet.
SOLUTIONS IMPLEMENTED5. Energy efficient design of the real estateA business model to transform the real estate with guaranteed cost savings.
The first step is to analyse the current energy state of existing buildings. Secondly, measures are set out. And finally, the buildings' energy technologies are overhauled, which includes: energy-saving contracts, monitoring, controlling, consultancy and performance optimisation.
SOLUTIONS IMPLEMENTED6. Steps for decarbonisation of district heatingMeasures to reduce district heating (DH) emissions by enabling the integration with renewable energy sources (RES).
An increasing share of RES is linked to a larger flexibility of the DH-system:
- Investigations on lowering the inlet temperatures of the DH system. To integrate RES, operating temperatures must be reduced. This minimises heat losses and emissions. Because of the thermo-hydraulic complexity of the DH-system, feasibility studies must be carried out.
- Heat storage expansion. To raise the flexibility of the DH-system, the volume of the existing heat storage must be expanded. This shifts peak loads by uncoupling CHP- or RES-based production and demand and helps to better react to the fluctuating availability of RES.
