  abstract  = {Es sollte herausgestellt werden, inwieweit kalte Vorbehandlungsverfahren das Deponierverhalten von mechanisch-biologisch vorbehandeltem Restm{\"u}ll beeinflussen. Das Deponierverhalten von mechanisch-biologisch vorbehandeltem Abfall wurde an Lysimeterversuchen simuliert. Die Ergebnisse zeigen, daß durch die mechanisch-biologische Behandlung des Abfalls eine CSB-Entfrachtung bezogen auf das Wasser-Feststoffverh{\"a}ltnis von ca. 70 \% erfolgt, die kumulierte TOC-Fracht um ca. 50 \% sinkt, die NH4-N-Konzentrationen eine Reduktion von ann{\"a}hernd 80 \% aufweist, die Gasproduktion um ca 80 \% f{\"a}llt. Insgesamt kann mit einer erheblichen Verk{\"u}rzung der Nachsorgephase gerechnet werden. - Neben den Lysimeteruntersuchungen wurden Staub- und Keimemmissionsmessungen im Handsortierbereich der MBRA durchgef{\"u}hrt. Die durchgef{\"u}hrten Keimemissionsmessungen ergaben, daß die dort Besch{\"a}ftigten im Vergleich zu anderen Arbeitsbereichen z.T. signifikant erh{\"o}hten Keimbelastungen ausgesetzt sind. Den gr{\"o}ßten Anteil der im Screening eindeutig bestimmten Bakterien hatten die Enterobakteriaceen, die Streptomyceten sowie Coliformen. Den gr{\"o}ßten Anteil am Pilzspektrum hatte die Gruppe der Penicillien. Die Differenzierung zeigte die Eigung von A. fumigatus als Leitkeim. - Die Staubmessungen erfolgten gleichzeitig mit den Keimemissionsmessungen. Die Analyse der Partikelzahlen in den unterschiedlichen Gr{\"o}ßenklassen zeigt, daß 95 \% der Aerosole einatembar, 90 \% thorakal- und 85 \% alveoleng{\"a}ngig sind. Des weiteren ergab die Korrelation der Partikelklasse > 2 bis < 5 Mikrometer und der Konzentration an luftgetragenen Pilzen eine signifikante {\"U}bereinstimmung. Bei zuk{\"u}nftigen Untersuchungen und routinem{\"a}ßigen Messungen durch die Aufsichtsbeh{\"o}rde oder im Rahmen der arbeitsmedizinischen Vorsorge k{\"o}nnte demnach auf die bew{\"a}hrte Meßgr{\"o}ße "Staubgehalt" zur{\"u}ckgegriffen werden.},

  abstract  = {The broad commercial objective of this project was the sustainable value creation in steel building technology by addressing the ways in which significant energy reductions can be made in the operation phase of multi-storey commercial buildings. A review on energy efficient commercial buildings in Europe has been carried out consisting of several case studies from different countries. The project included development of zero-energy concepts for reducing energy demand as well as concepts for heating, cooling and ventilation systems by utilising renewable energy sources in three different climates. Also alternative structural frame solutions were developed and analyzed in respect of structural and MEP (mechanical, electrical and plumbing solutions) features. An innovative long span floor system with integrated MEP routings promises a cost effective alternative for sophisticated ventilation distribution and radiant heating and cooling systems, allowing for high energy efficiency and high quality interior climate. The report includes also review of best architectural practices for integrated renewable energy solutions including different design strategies for building facades of zero energy buildings. Interesting results and design basis are also presented for steel energy pile concept, where structural foundation piles are utilized for ground energy harvesting. Life cycle cost calculations for near zero energy office building based on developed technologies show that a near zero energy construction is also profitable. The results and work methods of the project have been summarized in the form of design guidance that offers designers the knowledge gained in a form that can be easily understood.},

  abstract  = {Different analytical approaches exist to describe the structural substance or wear reserve of sewer systems. The aim is to convert engineering assessments of often complex defect patterns into computational algorithms and determine a substance class for a sewer section or manhole. This analytically determined information is essential for strategic rehabilitation planning processes up to network level, as it corresponds to the most appropriate rehabilitation type and can thus provide decision-making support. Current calculation methods differ clearly from each other in parts, so that substance classes determined by the different approaches are only partially comparable with each other. The objective of the German R\&D cooperation project 'SubKanS' is to develop a methodology for classifying the specific defect patterns resulting from the interaction of all the individual defects, and their severities and locations. The methodology takes into account the structural substance of sewer sections and manholes, based on real data and theoretical considerations analogous to the condition classification of individual defects. The result is a catalogue of defect patterns and characteristics, as well as associated structural substance classifications of sewer systems (substance classes). The methodology for sewer system substance classification is developed so that the classification of individual defects can be transferred into a substance class of the sewer section or manhole, eventually taking into account further information (e.g. pipe material, nominal diameter, etc.). The result is a validated methodology for automated sewer system substance classification.},
