Integrale Analyse von Bestandsbaumaßnahmen und vergleichende Nachhaltigkeitsbewertung
Bibliographic record
Abstract
Abstract Bauen im Bestand beschreibt im Allgemeinen die Verdichtung, Modernisierung und Sanierung von bestehenden Gebäuden. Unter dem Aspekt der Nachhaltigkeit liegt der Schwerpunkt des Bauens der nächsten Jahrzehnte im Bestand. Hierbei ergeben sich große Chancen für den Stahl(leicht)bau, die im Rahmen der vorgestellten Forschungsergebnisse aufgezeigt werden. Die interdisziplinäre Planung von Gebäudeerweiterungen in Form von Aufstockungen aus Stahl erfolgt für ausgewählte, repräsentative Referenzgebäude und liefert eine Basis für weitere, allgemeine Erkenntnisse zum Bauen im Bestand unter Berücksichtigung von stadtplanerischen und architektonischen sowie bauphysikalischen Aspekten, statisch‐konstruktiven Anforderungen, des Baubetriebs, der Immobilienbewertung und lebenszyklusübergreifenden Nachhaltigkeitsbewertungen. Im Ergebnis liegen erstmalig detaillierte Ökobilanzergebnisse für spezifische Bestandsbaumaßnahmen vor, die eine Vorteilhaftigkeit gegenüber Abriss und Neubau ausweisen. Integral analysis of building projects dealing with existing structures including comparative assessments of sustainability – Exemplified through investigations of the building for the physics institute at the TU Dortmund, Germany. Building in existing contexts and structures considers urban densification, modernization and redevelopment of the existing building stock in general. Aspects of sustainability will primarily be focusing on refurbishment and restoration of existing buildings; they will be the challenge of future. These future developments unfold many opportunities for the application for steel and steel‐lightweight structures, which are highlighted through this presented research project. The interdisciplinary planning approach of roof top extensions for existing buildings with steel structures is simulated for selected, representative reference buildings and can be used to facilitate a basis for further insights in respect to building with existing structures. This approach considers city planning and architectural requirements, aspects of building physics, structural solutions, building process concerns, real estate assessment, sustainability and life cycle assessments. As a result, for the first time detailed outcomes regarding the life cycle assessments for specific projects dealing with the composition of existing structures in contrast to the process of demolition and new development are available. An advantage of building in existing context can be determined.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
