Stuttgart, Germany

Overview

Stuttgart, the capital city of the federal state of Baden-Württemberg, is situated in the South-West of Germany. The city of Stuttgart has 634,000 inhabitants, while the Stuttgart region has about 2.8 million residents. It is one of Germany’s major economic and cultural hubs.

ConnectHeat activities will focus on the Housing and Urban Development Corporation (SWSG). The latest energy report from 2018 indicates a primary energy consumption of 16.212 GWh/year for Stuttgart, with the main sectors being trade commerce (33%) and housing (31%). The renewable energy production amounts to 0.6 % in the city, and the balanced amount of renewable energy to 18.5%.

The pilot project in Stuttgart is a collaborative initiative in the field of heating and cooling by tenants of social housing. The houses that are participating in this collective action are managed by the SWSG. The approach involves educating tenants on energy-saving practices, incentivising behaviour changes through financial and non-financial rewards, and fostering a collaborative environment through an energy efficiency network. Key benefits include cost savings for tenants, reduced CO2 emissions, improved energy efficiency, and enhanced community collaboration and support. Another benefit of the project is the promotion of the concept of energy communities and citizen initiatives.

Energy size

There will not be any thermal power and energy supply installed as this pilot case has a focus on energy savings. The annual energy savings come from the tenant’s behavioral changes through the educational program, financial incentives etc. are expected to reach 10 kWh/m2/y.

Ambition, vision and expected objectives

  1. To engage consumers, community representatives and other stakeholders and raise awareness on EE, DHC systems, RES solutions and possible business models.
  2. To analyse two different approaches and investigate several measures to reduce fossil energy consumption and increase energy efficiency: a technical approach as an AI-control (artificial intelligence) system and a citizen-led approach as an activation and motivation campaign including financial and nonfinancial innovative incentive systems for tenants to influence their energetic behaviour towards more energy efficiency.
  3. To support the local community to use the outcomes together with analysis of increasing the share of RES in DHC systems to transfer the methods to other community energy initiatives throughout Stuttgart.
