TY - THES A1 - Lützkendorf, Thomas T1 - Beiträge zur Umsetzung von Prinzipien einer Nachhaltigen Entwicklung im Baubereich T1 - Realising principles of sustainable development in the building sector N2 - Die nach dem kumulativen Verfahren verfasste Habilitationsschrift fasst in 3 Kapiteln wissenschaftliche Beiträge des Autors aus den Jahren 1995 – 1999 zusammen. Kapitel 1 befasst sich mit Fragen einer Integration von Aspekten des energiesparenden, ressourcenschonenden und gesundheitsgerechten Bauens in die Prozesse der Planung und Entscheidungsfindung. Dargestellt werden u.a. die methodischen Grundlagen für die Ermittlung und Bewertung des Energie- und Stoffstromes während des Lebenszyklusses von Bauwerken, eine Systematik energiebezogener Grenz- und Zielwerte sowie eine Analyse verfügbarer Planungs- und Bewertungshilfsmittel. Im Kapitel 2 wird ein System zur Sicherung der Qualität bei der Planung und Errichtung von Niedrigenergiehäusern vorgestellt sowie dessen Wechselwirkung mit Energieausweisen und Gebäudepässen diskutiert. Kapitel 3 analysiert Unterschiede und Gemeinsamkeiten einer ökologischen Bewertung von Standort, Unternehmen, Prozess und Produkt. N2 - The inaugural dissertation, produced according to the cumulative approach, organises the author’s scientific writings produced between the years 1995 and 1999 into three chapters. Chapter 1 is concerned with questions of integrating energy-saving, resource friendly and health-oriented approaches to building into the planning and decision-making processes. Methodical approaches to determining and evaluating energy and mass flow during the life-cycle of buildings are discussed, a framework for energy-related limit and target values examined and available planning aids and assessment tools analysed. In chapter 2 a system for ensuring quality control in the planning and construction of low-energy houses is introduced and its correspondence to energy passports and building certification methods discussed. Chapter 3 examines the differences and parallels between the ecological assessment of location, business, process and product.

Die letzten 20 Jahre sind eine kurze Zeit in der tausendjährigen Geschichte der Stadt, trotzdem entwickelte sich die Stadt in diesem Zeitraum am schnellsten und auch am problematischten aus Sicht der Umwelt. Ohne eine passende Entwicklungsstategie oder eine geeignete Maßnahme bei der Stadtplanung vergrößert sich der Konflikt Ökonomie - Ökologie immer weiter. ... Die Findung eines neuen Wohnkonzeptes im Gleichgewicht zwischen Ökonomie und der Ökologie ist eine hochaktuelle Frage geworden. N2 - The climat change, the enlargement of the ozone hole, the destruction of forests, the desertification and the other negative effects, which are cused by human daily activities, become global issues. However, they are particularly serous in developing and newly industialized countries. Vietnam has to face such problems as well. Under this circumstance, human beings are both offenders and victims. Environment-friendly or not? Economy with or without ecology? As living dreatures in nature human beings must answer these questions themselves and react on these challenge in time.

Architects and planners are the key players for reducing the environmental impacts of buildings, as they define them to a large extent. Life Cycle Assessment (LCA) allows for the holistic environmental analysis of a building. However, it is currently not employed to improve the environmental performance of buildings during the design process, although the potential for optimization is greatest there. One main reason is the lack of an adequate means of applying LCA in the architectural design process. As such, the main objective of this thesis is to develop a method for environmental building design optimization that is applicable in the design process. The key concept proposed in this thesis is to combine LCA with parametric design, because it proved to have a high potential for design optimization. The research approach includes the analysis of the characteristics of LCA for buildings and the architectural design stages to identify the research gap, the establishment of a requirement catalogue, the development of a method based on a digital, parametric model, and an evaluation of the method. An analysis of currently available approaches for LCA of buildings indicates that they are either holistic but very complex or simple but not holistic. Furthermore, none of them provide the opportunity for optimization in the architectural design process, which is the main research gap. The requirements derived from the analysis have been summarized in the form of a catalogue. This catalogue can be used to evaluate both existing approaches and potential methods developed in the future. In this thesis, it served as guideline for the development of the parametric method – Parametric Life Cycle Assessment (PLCA). The unique main feature of PLCA is that embodied and operational environmental impact are calculated together. In combination with the self-contained workflow of the method, this provides the basis for holistic, time-efficient environmental design optimization. The application of PLCA to three examples indicated that all established mandatory requirements are met. In all cases, environmental impact could be significantly reduced. In comparison to conventional approaches, PLCA was shown to be much more time-efficient. PLCA allows architects to focus on their main task of designing the building, and finally makes LCA practically useful as one of several criteria for design optimization. With PLCA, the building design can be time-efficiently optimized from the beginning of the most influential early design stages, which has not been possible until now. PLCA provides a good starting point for further research. In the future, it could be extended by integrating the social and economic aspects of sustainability.
