CHALLENGES
Community retrofit - District renewal systems
Community retrofit and district renewal includes retrofitting buildings to make them more energy-efficient and better at withstanding extreme weather induced by climate change, while also improving amenities for the buildings’ occupants. Thermal-energetic upgrades and the optimization of building services are both key to improving energy efficiency.
-
Reimagining supply chains to enable circular construction
-
Assessing the carbon footprint and life cycle of buildings in order to achieve zero-emission buildings
-
Efficient heating/cooling systems
-
Heating/cooling systems based on electricity
-
Energy storage systems for the building sector
-
Sustainable building renovation solutions
-
Low carbon embedded materials for construction
-
Positive Clean Energy Districts
Green spaces, climate resilience & urban adaptation systems
Investing in nature can help to address climate risks, bolster public health, and improve community vitality. This can include, but is not limited to, strategic interventions using nature-based solutions in various areas around the city and using new models for engaging citizens.
-
Efficient use and management of water in urban environments
-
Nature-based solutions for the physical transformation of public spaces to improve the health and well-being of citizens
-
Urban shade
-
Income-generating activities related to natural spaces in cities (ecosystem services)
-
Planning support tools
-
Direct air capture technologies for urban environments
Mobility, logistics, & public space systems
Mobility, logistics, and public space systems are challenging topics for many cities. These topics give rise to important questions such as: How does public space affect the sustainability of urban mobility in contemporary cities? How does facilitating mobility contribute to livability? How can public-private partnerships trigger shifts in commuting and mobility that have a systemic benefit for all?
-
Building sustainable infrastructure—physical and digital—that supports innovative mobility solutions
-
Promoting public transportation and discouraging private driving and parking
-
Electric mobility and charging infrastructure
-
Solutions for a “15-minute” city
Renewable energy systems
Renewable energy sources—e.g. geothermal energy and low-temperature waste heat—are needed in order to upgrade district heating and increase the share of distributed electricity generation. The use of state-of-the-art technologies, high awareness about environmental and energy issues, and decentralized renewable energy supplies in urban neighborhoods will all play a crucial role in activating private households and local administrations.
-
Photovoltaic technology
-
Development of energy communities for the deployment of decentralized renewable energy solutions
-
Tools for verifying the fulfillment of energy efficiency/carbon footprint standards for projects
-
Mapping available building roofs for energy generation
Information & data systems
Cities have different strategies for decarbonization that typically involve a combination of different solutions, approaches, and economic sectors. However, information, data, tools, and processes are crucial to achieving their long-term goals. For example, data systems can help municipalities become more efficient, effective, and evidence-based. They could also be used to adapt or fundamentally change processes or regulations that contribute to the acceleration of decarbonization.
-
Data management for decarbonization
-
Life cycle and carbon footprint analysis to support urban decarbonization processes
-
Methodologies and tools for carbon absorption assessment
-
