Climate-Neutral Buildings and Neighbourhoods

Climate-neutral urban districts are well-prepared for the future and provide their residents with a livable and secure environment. They are characterized by high residential and living quality, renewable energy supply, attractive mobility options, good infrastructures, sufficient green and recreational spaces, as well as participation and a strong sense of social cohesion.

The development and demonstration of energy-efficient building and energy technologies are central components of the transformation towards a "Climate-Neutral City." Equally important are studies on the systemic interactions between buildings, building technologies, and energy infrastructure.

To realize climate-neutral neighborhoods, it requires, on one hand, technological (further) developments in the structural infrastructure. The focus here is on the use of resource-efficient materials and the implementation of components to enhance energy efficiency in new construction and renovation.

On the other hand, it involves the combination and interoperability of technological (sub-) systems. Numerous different individual technologies and components must be integrated into an interconnected, interoperable, and energy-efficient overall system in the future.

Adjusting legal frameworks and developing new sustainable business models for the construction, operation, and renovation of buildings are also crucial research topics.

Climate-neutral buildings and neighborhoods exhibit the following characteristics:

High building quality in terms of construction materials in new construction and renovation.
High energy efficiency and a positive annual energy balance.
Use of renewable energy.
High self-utilization rate of energy provided on-site or regionally.
Sector coupling of electricity, heat, and mobility.
Flexibility, grid compatibility, and grid service.
Use of digital tools in all phases of the life cycle.
Utilization of synergies in mixed-use.
Implementation of the circular economy.
