To analyze the emissions reduction potential, we conducted a comparative life cycle assessment of a proton exchange membrane fuel cell in a residential application and a conventional system with a stand-alone gas condensing boiler and electricity from a grid mix. The period under review was referred to as the service life of the PEMFC and is assumed to be 10 years (83,038 h of PEMFC). The applicability of this in a single-family house built between 1991 and 2000 under German climatic conditions was investigated. The functional unit is set to the thermal energy demand of 16,244 kWh/a and electricity demand of 4919 kWh/a of a single-family house. The impact assessment method “CML 2001–August 2016” was used in this investigation. The manufacturing phase of the proton exchange membrane fuel cell showed disadvantages, whereby the use phase had significant advantages in most of the environmental impact categories as compared to the conventional energy supply system. Considering the whole life cycle, the advantages from the use phase could outperform the disadvantages from the manufacturing phase in most of the impact categories, except for ADP elements and TETP.

März 1991 bis 31. Dezember 2009 N2 - Diese Studie soll aufzeigen, wie sich das Akkreditierungswesen in Deutschland über einen Zeitraum von mehr als 25 Jahren entwickelt hat. Die Bundesanstalt für Materialforschung und -prüfung (BAM) und der Deutsche Akkreditierungsrat DAR haben bei dieser Entwicklung wichtige Beiträge geleistet. Leitmotiv dieser Studie ist eine These des Philosophen Udo Marquard, zitiert im Vorwort der BAM Chronik 1871-1996, „Die neue Welt kann nicht sein ohne die alten Fertigkeiten – Zukunft braucht Herkunft“. Die Erfahrungen bei der Entwicklung des deutschen Akkreditierungssystems sollen zusammengefasst werden, um Schlussfolgerungen für die Zukunft ableiten zu können, da bisher keine zusammenfassende und überblicksmäßige Darstellung des gesamten Entwicklungsprozesses vorhanden ist. Ziele dieser Studie sind die Darstellungen — der Beiträge des deutschen Akkreditierungssystems zur gegenseitigen Anerkennung von Zertifikaten und Prüfberichten in der EU zur Mitgestaltung des gemeinsamen Marktes der EU und zum Abbau internationaler tarifärer Handelshemmnisse, - der Komplexität von Akkreditierung und Konformitätsbewertungsvorgängen in einzelnen Problemkreisen, - der Entwicklung des deutschen Akkreditierungssystems von den Anfängen bis zur Tätigkeitsaufnahme der Deutschen Akkreditierungsstelle (DAkkS GmbH) am 1. Januar 2010, - der Rolle des Deutschen Akkreditierungsrates (DAR) (04.03.1991 bis 31.12.2009) anhand wichtiger Eckdaten und Hauptergebnisse aus seinem Präsidium und den vier Ausschüssen, ATF DAR-Ausschuss für Technische Fragen AIZ DAR-Ausschuss für Internationale Zusammenarbeit AZ DAR-Ausschuss für Zusammenarbeit gesetzlich geregelter und gesetzlich nicht geregelter Bereich ABT DAR-Ausschuss für Begutachtertraining - der Wege zum Finden eines nationalen Konsenses mit mehreren privaten und staatlichen Akkreditierungsstellen, um eine einheitliche Außenvertretung in internationalen Gremien zu gewährleisten, - der ständigen Bemühungen um enge Zusammenarbeit zwischen gesetzlich nicht geregeltem und gesetzlich geregeltem Bereich, - der Aktivitäten und Ergebnisse, um zu einem einheitlichen deutschen Akkreditierungssystem zu gelangen, der Rolle der BAM im deutschen Akkreditierungswesen, der Entstehung des BAM-Akkreditierungssystems (BAS) und seine Überleitung in das Deutsche Akkreditierungssystem Prüfwesen (DAP), - der Führung der Geschäftsstelle des DAR und des Akkreditierungsbeirats (AKB) des Bundesministerium für Wirtschaft und Energie (BMWi) (2006 bis 2009 und ab 2010) - der Tätigkeiten des BAM-Evaluierungsausschusses.

This affects the overall environmental footprint, but the question is how? A number of European policy strategies, initiatives and measures, such as the Green Deal, the Circular Economy Action Plan,the Ecodesign Directive and the EU Energy Labelling, aim to ensure that the environmental impact of the overall product is better determined, communicated and finally reduced. A core element of these efforts is the DIN EN 4555x series of standards. However, there is currently no comprehensive and systematic classification of the additional product functions or an approach to assess the associated positive and negative environmental impacts. Therefore, we present in this study an environmental assessment approach for additional product functions and illustrate its application in the case of fridge-freezers. A key element of the life-cycle-oriented methodology is an assessment matrix to categorize and evaluate the direct, indirect and systemic impacts of products’ functions. Based on semiquantitative assessments of experts, the matrix provides an indication of how the additional function affects the overall environmental product impact as well as specific product aspects such as durability or reparability. Based on the results experts can discuss and better understand how specific functions can influence various stages of the product life cycle and how intended systemic changes or rebound effects could occur. As part of the approach, a representative survey was conducted to analyze consumers’ knowledge and information needs. Based on the results, recommendations for purchasing decisions and the consumer information were developed. This paper presents the results from the assessment of the additional functions of fridge-freezers.

The method allows for testing with unfixed compressor speed and active control of the unit. Thus, at low part loads the unit under test is allowed to cycle on-off, when the frequency of the compressor drops below its minimum threshold. Therefore, the associated efficiency losses are directly measured and correction calculations as for the current steady state tests become obsolete. In addition, the testing can be performed without the support of the manufacturer by market surveillance authorities, for instance, since no frequency and expansion valve settings are required. To prove that the compensation method is repeatable and reproducible three round robin tests have been organised by BAM.
