Energiesuffizienzpolitik mit Schwerpunkt auf dem Stromverbrauch der Haushalte
Der Abschlussbericht des dritten Arbeitspakets im Projekt "Energiesuffizienz" entwickelt aufbauend auf den Erkenntnissen der vorhergehenden Projektarbeiten Empfehlungen für ein integriertes Paket von Energiesuffizienzpolitiken im Feld Bauen/Wohnen. Der Fokus liegt auf dem Stromverbrauch in Haushalten. Dafür werden zunächst Leitlinien für die Governance von Energiesuffizienz und eine Methodik für die analytische Herleitung einer Energiesuffizienzpolitik entwickelt. Diese Analyse betrachtet Mikro- (Individuum) und Mesoebene (Haushalts-/Versorgungsökonomie). In sieben Schritten wird ein integriertes Politikpaket für Energieeffizienz und Energiesuffizienz entwickelt und eine juristische Kurzeinschätzung gegeben. Das Paket umfasst unter anderem eine Weiterentwicklung von Ökodesign und EU-Energielabel, eine integrierte Energieberatung sowie Förderprogramme für Geräte, die einen suffizienten Gebrauch ermöglichen, und für ressourceneffiziente Dienstleistungen, die Geräte im Haushalt ersetzen können. Zudem werden als Teil des Politikpakets auch übergreifende Politikansätze (Stromkundenkonto, Politikinstrumente zur Begrenzung des Wachstums der Pro-Kopf-Wohnflächen) analysiert.Abschlussbericht zu Arbeitspaket 3. Projekt "Energiesuffizienz - Strategien und Instrumente für eine technische, systemische und kulturelle Transformation zur nachhaltigen Begrenzung des Energiebedarfs im Konsumfeld Bauen / Wohnen" BMBF/FONA FKZ 01 UN 1214 B.This final report of the third Work Package within the research project "Energy Sufficiency" develops an integrated energy sufficiency policy package in the field of buildings, with a focus on household electricity consumption. It builds on the insights of previous work within the project. In a first step, governance guidelines for energy sufficiency policies are outlined and a methodology for the analysis and development of energy sufficiency policy approaches is developed. The analysis differentiates between micro and macro levels (individual vs. care economy). In a 7-step approach, an integrated policy package for energy efficiency and sufficiency is developed, and instruments are briefly assessed as to their legal viability. The policy package includes, i.a., amendments to the EU's ecodesign and energy labelling directives, an integrated energy advice, and financial incentives for appliances that enable their sufficient use as well as for resource-efficient services that may replace appliances in the household. In addition, overarching policy approaches (energy company obligation for absolute energy reduction, policies for limiting heated floor areas) are assessed, complementing the policy package
Energy sufficiency policy : how to limit energy consumption and per capita dwelling size in a decent way
Energy sufficiency has recently gained increasing attention as a way to limit and reduce total energy consumption of households and overall. This paper presents selected results of a research project funded by the German Federal Ministry of Education and Research that examined the potentials and barriers for energy sufficiency with a focus on electricity in households, how household members perceive sufficiency practices, and how policymakers could support and encourage these. Bottom-up calculations for an average 2-person household in Germany yielded a total electricity savings potential from energy efficiency and sufficiency combined of theoretically up to 75 %.
The continuous growth of per capita living space was identified as one important driver for additional energy consumption both for heat and electricity. The paper will present findings of a representative survey of 600 persons responsible for the housework. It revealed that a part of the households is already practicing sufficiency options or are open towards these. Up to 30 % of these households can imagine, given the right conditions and policy support, to move to a smaller dwelling or to share an apartment with others when they are older.
Results of a first comprehensive analysis of an energy sufficiency policy to encourage and support households to sufficiency practices form the second part of the paper, with a focus on the feasibility and potential effectiveness of instruments for limiting the growth in average living space per person. This includes a case study on fostering communal housing projects as a measure to reduce living space. Further, the feasibility of a cap scheme for the total electricity sales of a supplier to its customers was examined. Instruments supporting energy-efficient and sufficient purchase and use of equipment complete the integrated energy sufficiency and efficiency policy package.
The paper will finally present the project's conclusions on an integrated energy sufficiency policy package resulting from this analysis
Outcomes of Shoulder Arthroplasty Performed for Postinfectious Arthritis.
Background: The purpose of this study was to evaluate the functional outcomes, infection rate, and complications associated with shoulder arthroplasty for sequelae of prior septic arthritis.
Methods: This is a retrospective cohort study of 17 patients who underwent shoulder arthroplasty for sequelae of septic arthritis. Patients were analyzed for patient-reported outcomes, complications, and reoperations.
Results: The 17 patients in this cohort were an average age of 65.4 ± 12.2 years old, were 58.8% male, and had an average body mass index of 27.9 ± 4.1 kg/m
Conclusions: Shoulder arthroplasty after septic arthritis had inconsistent functional outcomes and high complication rates but no reinfection
More than energy savings : quantifying the multiple impacts of energy efficiency in Europe
Energy efficiency improvements have numerous benefits/impacts additional to energy and greenhouse gas savings, as has been shown and analysed e.g. in the 2014 IEA Report on "Multiple Benefits of Energy Efficiency". This paper presents the Horizon 2020-project COMBI ("Calculating and Operationalising the Multiple Benefits of Energy Efficiency in Europe"), aiming at calculating the energy and non-energy impacts that a realisation of the EU energy efficiency potential would have in 2030. The project covers the most relevant technical energy efficiency improvement actions and estimates impacts of reduced air pollution (and its effects on human health, eco-systems/crops, buildings), improved social welfare (incl. disposable income, comfort, health, productivity), saved biotic and abiotic resources, and energy system, energy security, and the macroeconomy (employment, economic growth and public budget). This paper explains how the COMBI energy savings potential in the EU 2030 is being modelled and how multiple impacts are assessed. We outline main challenges with the quantification (choice of baseline scenario, additionality of savings and impacts, context dependency and distributional issues) as well as with the aggregation of impacts (e.g. interactions and overlaps) and how the project deals with them. As research is still ongoing, this paper only gives a first impression of the order of magnitude for additional multiple impacts of energy efficiency improvements may have in Europe, where this is available to date. The paper is intended to stimulate discussion and receive feedback from the academic community on quantification approaches followed by the project

Impact chains of energy sufficiency policies: A proposal for visualization and possibilities for integration into energy modeling
Impact chains are used in many different fields of research to depict the various impacts of an activity and to visualize the system in which this activity is embedded. Research has not yet conceptualized impact chains specifically for energy sufficiency policies. We develop such a concept based on current evaluation approaches and extend these by adding qualitative elements such as success factors and barriers. Furthermore, we offer two case studies in which we test this concept with the responsible climate action managers. We also describe options for integrating these impact chains into different types of energy models, which are key tools in policy consulting.Impact chains are used in many different fields of research to depict the various impacts of an activity and to visualize the system in which this activity is embedded.

Profibus network in the instrumentation and control laboratory
The Instrumentation and Process Control Laboratory is facility that provides Engineering students a way of performing control experiments by using a combination of instrumentation hardware and LabVIEW programs. The Laboratory is based upon three components:
- The Experimental Stations
- The Master I/O Program
- The Basic Experimental Template
The Experimental stations are panels where hardware components like valves and measuring devices are connected to. The Master I/O program is a LabVIEW program which acts as an interface between the Experimental Stations and the Basic Experimental Template. The Basic Experimental Template is a LabVIEW program which stundents can modify to suit their designs for process control experiments.
The main aim of this project is to integrate the PROFIBUS PA instruments into the Master Input/Output (I/O) program and to produce a guide to assist students in using these instruments. This project involves communication between instruments from different vendors, hence the use of open and vendor independent protocols.
Once completed, the project will avail more instruments to be used for process control experiments. The project also avails another infrastructure for students studying Industrial Computer Engineering to use the physical PROFIBUS network when learning about industrial communication systems. Even though PROFIBUS PA instruments are more accurate and fast, their response in controlled by the scan cycle of the Master I/O Program.
The communication protocols used in this project are PROFIBUS PA, OLE for Process Control (OPC) and Ethernet. The PROFIBUS protocol is vendor independent and based on the master and slave architecture. The SIEMENS CPU314C-2DP is used as the master, while the slaves are the Siemens DP/PA coupler, Levelflex M FMP40 and Deltbar S PMD70. Communication between the slaves and the master was via the PROFIBUS PA protocol. The configuration and programming of the SIEMENS CPU314C-2DP and PROFIBUS PA devices was done using TIA Portal V13 software.
Communication between an OPC server and CPU314C-2DP was via a serial communication port using an MPI cable. The OPC server was configured to read the required data from the iv CPU314C-2DP. The Master I/O program was updated to read data from the OPC server using shared variables and calculate the measured parameters. The OPC server and Master I/O program were running on the same computer. Finally, the experimental template was updated to read data from the Master I/O program using Ethernet as the medium of communication.
The communication and programs were tested at the end of each stage to ensure functionality of each segment. In overall, the objectives of this project were achieved as the PROFIBUS PA instruments can now be used in the laboratory, and the guide on how to use them was developed
