    Notes: Sowohl bei der biologischen als auch bei der thermischen Zersetzung von organischen Abfällen entsteht Methan. Die Methan-Bildung verläuft in der Deponie unkontrolliert. Die Gewinnung von Methan ist dabei unvollständig. Bei der biologischen Zersetzung wasserreicher organischer Abfälle in geschlossenen beheizten Behältern läßt sich gezielt Methan gewinnen. Thermische Prozesse zur Methan-Gewinnung (Ent- und Vergasung) befinden sich noch in Entwicklung. Voraussichtlich werden sie nur in Sonderfällen von Interesse sein. Für die großindustrielle Gaserzeugung aus Abfällen sind die Müllmengen in wirtschaftlich erträglichen Einzugsgebieten zu klein.

    Description / Table of Contents: The electronic structure and conformation of PVC-oligomer models is investigated, using the EHMO (extended Hückel) approximation. Calculated geometries of conformers are near those with idealized torsional angles. Syndiotactic PVC sequences are by 6 kJ mol-1 more stable than the isotactic helical structure. For changing the conformation of 2,4-dichloropentane a coupled internal rotation of neighbouring C—C bonds is important.
    Notes: Die Elektronenstruktur und Konformation von PVC-Oligomer-Modellen wird mit Hilfe der semiempirischen EHMO (erweiterter Hückel)-Methode untersucht. Berechnete Konformergeometrien liegen in der Nähe der idealisierten Torsionswinkel. Syndiotaktische PVC-Sequenzen sind ca. 6 kJ mol-1 stabiler als eine isotaktische Helix. Für den Konformationswechsel im 2,4-Dichlorpentan ist die gekoppelte innere Rotation um benachbarte C—C-Bindungen wesentlich.

    Description: The implementation of energy efficiency improvement actions not only yields energy and greenhouse gas emission savings, but also leads to other multiple impacts such as air pollution reductions and subsequent health and eco-system effects, resource impacts, economic effects on labour markets, aggregate demand and energy prices or on energy security. While many of these impacts have been studied in previous research, this work quantifies them in one consistent framework based on a common underlying bottom-up funded energy efficiency scenario across the EU. These scenario data are used to quantify multiple impacts by energy efficiency improvement action and for all EU28 member states using existing approaches and partially further developing methodologies. Where possible, impacts are integrated into cost-benefit analyses. We find that with a conservative estimate, multiple impacts sum up to a size of at least 50% of energy cost savings, with substantial impacts coming from e.g., air pollution, energy poverty reduction and economic impacts.

    Description: Any energy efficiency impact evaluation can be done from different analytical perspectives, e.g. the investor/end-user perspective, program administrator perspective or the societal perspective. COMBI applies the "societal perspective", as this is most relevant for policy-making. COMBI draws on a reference scenario until the year 2030 including existing (partially already ambitious) policies. By modelling 21 sets of "energy efficiency improvement" (EEI) actions, a second efficiency scenario was modelled amounting to additional energy savings of around 8% p.a. in 2030, that is comparable to the EUCO+33 to EUCO+35 scenario. This D2.7 quantification report summarises the quantification approaches applied in the COMBI project and main project findings. It therefore draws on other COMBI reports that contain this information in greater detail in order to summarise quantifications. The report is structured in three main sections: 1. The COMBI approach and methods, explaining key methodological approaches both for individual impact quantifications and for the aggregation of impacts 2. Quantification results, giving an overview on main figures of quantified indicators and 3. Insights from cross-impact analysis, which gives a comparison between monetised impacts and presents their use for Cost-Benefit calculations in the COMBI online tool.
