TransParEnergy is developing an innovative methodology for standardizing and linking different building data in order to create digital energy twins of entire districts or cities. To date, there is hardly any comprehensive and up-to-date energy data at the level of individual buildings, but this forms the basis of such an energy twin. The aim is therefore to efficiently record different sources of information and data formats relevant to the energy assessment of buildings, anonymize them if necessary and systematically evaluate them. This creates a sound database for local authorities, municipal utilities and planners to plan measures such as district heating networks or energy refurbishments precisely and economically.

The focus is on improving the availability and quality of building energy information. This also benefits owners, who receive tools to assess and optimize their energy consumption, while municipalities can use realistic energy demand forecasts at regional level. This data enables the planning of energy-efficient, climate-friendly measures and contributes to the achievement of climate targets.
