EN.E.A. (original title: Entscheidungsprozesse zu Erhalt oder Abbruch von Bestandsgebäuden) seeks to develop a practical guideline enabling stakeholders to make transparent, evidence-based decisions on building preservation or demolition.

Phase one examines existing decision-making practices and identifies decisive pull and push factors. These lay the groundwork for practical insights and a schematic process overview, forming the basis for an initial guideline draft.
