As energy systems transition towards a growing share of renewable energy sources and technological complexity, environmental impacts that affect more than just GHG emissions, such as resource extractions, water and land use impacts or impacts on human health, are becoming increasingly relevant. To address this gap, this thesis introduces an automated coupling procedure for energy system modeling (ESM) and life cycle assessment (LCA). The implementation includes general recommendations and a practical coupling of the Open Energy Modelling Framework (oemof) based Spreadsheet Energy System Model Generator (SESMG) with a suitable LCA software. The LCA procedure involves goal and scope definition, inventory analysis, impact assessment, and interpretation. To adapt these steps to different energy system models, the LCA should be attributional, process-based and territorial. Further, the openLCA software by Green-Delta serves as a suitable soft-linking tool. The main challenge of the coupling procedure is the inventory analysis. Data collection faces limitations, reasoned by the commercialization and high maintenance efforts in open-source databases. After evaluating free databases, the Prozessorientierte Basisdaten f{\"u}r Umweltmanagement-Instrumente (ProBas) database of the Umweltbundesamt emerged as the most suitable choice for the coupling. However, also this database lacks traceability of datasets or compatibility with a comprehensive impact assessment. A generalized framework for the LCA application of energy systems was developed. The framework is based on an ex-post LCA assessment that considers the combination of the two approaches within every step of the procedure. Main considerations of this framework include automatic calculations of the inventory analysis and the impact assessment for different energy technologies, as well as calculations summed up for all technologies of energy system scenarios. Further, technology mapping and data harmonization are essential considerations for the automatic coupling and double counting of impacts needs to be avoided. Subsequently, the framework is realized with the adaption of the SESMG. Its database-independent realization allows compatibility with different databases in openLCA. For the selected ProBas database, the tool can be used with different available energy technologies. The use of unit processes is encouraged for data harmonization. Result interpretation of the LCA (in general or with the SESMG) should not solely focus on the absolute values of the impact categories, but rather on the comparative strengths among scenarios and technologies. The successful application to a reference single-family building using the ProBas database revealed varied environmental impacts, in relation with a higher reduction in GHG emissions, with an increase of 11 \% in terrestrial acidification impacts in the emission-optimized scenario. These findings emphasize a more comprehensive perspective on environmental impacts and provide a valuable validation of the developed methodology. Future research should include the improvement of data harmonization, the inclusion of more datasets for a more customized analysis of energy systems and more applications. The coupled approach offers a promising avenue for gaining deeper insights into optimizing urban energy systems.}, language = {en} } @techreport{Budde2022, type = {Working Paper}, author = {Budde, Janik}, title = {Residential load profile tools - A review and comparison of applied tools}, doi = {10.25974/fhms-17857}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:836-opus-178573}, pages = {16}, year = {2022}, abstract = {The energy demand of the residential sector contributed to about 29 \% of Germany's final energy consumption in 2020.

Load profiles for electricity, space heating and domestic hot water (DHW) are investigated. A total of ten tools were applied. It turns out that the selected load profiles are dependent on the field of application. Load profiles influence the results of energy system modeling and therefore it is important to differentiate load profile tools. Standardized load profiles are well suited when a large number of buildings are considered. Stochastic load profiles, behavioral load profiles and the reference load profiles are well suited for building-specific simulations. Physical load pro- files are well suited for single building models, but as soon as several buildings are considered, the input effort for a sufficient accuracy is high.}, language = {de} } @misc{MesenhoellerJacobsVennemann2022, author = {Mesenh{\"o}ller, Eva and Jacobs, Steffen and Vennemann, Peter}, title = {Raumstr{\"o}mung bei instation{\"a}rem Betrieb von RLT-Anlagen - Experimentelle und numerische Untersuchungen mit PIV und CFD}, doi = {10.25974/fhms-17860}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:836-opus-178605}, year = {2022}, abstract = {Posterzusammenfassung der Hintergr{\"u}nde, Ziele, Methoden (messtechnisch und numerisch) und Ergebnisse im Projekt zu instation{\"a}rer L{\"u}ftung.}, language = {de} } @misc{MesenhoellerVennemannHussong2019, author = {Mesenh{\"o}ller, Eva and Vennemann, Peter and Hussong, Jeanette}, title = {Raumstr{\"o}mungsmessung mit Particle Image Velocimetry (PIV) - Instation{\"a}rer Betrieb von RLT-Anlagen}, doi = {10.25974/fhms-17859}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:836-opus-178597}, year = {2019}, abstract = {Posterzusammenfassung der Hintergr{\"u}nde, Ziele, Messprinzipien, Messungen und des Versuchsstandes im Projekt zur Untersuchung instation{\"a}rer Rauml{\"u}ftung.}, language = {de} } @misc{MesenhoellerVennemann2018, author = {Mesenh{\"o}ller, Eva and Vennemann, Peter}, title = {Raumstr{\"o}mungsmessung mit Particle Image Velocimetry - Instation{\"a}rer Betrieb von RLT-Anlagen}, doi = {10.25974/fhms-17858}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:836-opus-178587}, year = {2018}, abstract = {{\"U}berblick {\"u}ber Methodik, Hintergr{\"u}nde und Ziele des Projekts zu instation{\"a}rer Rauml{\"u}ftung sowie bisherige Untersuchungsschwerpunkte auf diesem Gebiet.}, language = {de} } @inproceedings{TocklothKlemmBeckeretal.2024, author = {Tockloth, Jan N. and Klemm, Christian and Becker, Gregor and Blankenstein, Benjamin and Vennemann, Peter}, title = {Der Spreadsheet Energy System Model Generator (SESMG): Ein Tool zur Optimierung urbaner Energiesysteme}, series = {16.

Klassische Planungsmethoden kommen an ihre Grenzen. Die Energiesystemmodellierung (ESM) bietet eine M{\"o}glichkeit, ein Energiesystem hinsichtlich der Kosten und der Treibhausgas (THG)- Emissionen zu optimieren. Gleichzeitig ergibt sich aus der Energiewende und angestrebten THG-Neutralit{\"a}t ein akuter Handlungsbedarf. Dies gilt auch f{\"u}r die 1 500 Kasernen in Deutschland. Im Rahmen dieser Arbeit werden der bestehende Modellierungsprozess des Spreadsheet Energy System Model Generator (SESMG) erweitert, indem Herausforderungen der Modellierung und Optimierung von Kasernen identifiziert und L{\"o}sungsans{\"a}tze hierzu entwickelt werden. Diese Arbeit basiert auf der ESM einer realen Kaserne. Es kann das Urban District Upscaling Tool zur Erstellung der f{\"u}r den SESMG ben{\"o}tigten Modelldefinition verwendet werden. Die Open-Source Datenbank SESMG-Data, kann automatisch die ben{\"o}tigte Standard Parameter Tabelle mit zugeh{\"o}rigem Bericht generieren. Weiterhin wurde ein Energieaustauschmodell vorgestellt, das den Energieaustausch zwischen Kasernen eines Bilanzkreises erm{\"o}glicht. Ein Fokus liegt auf der Abbildung zuk{\"u}nftiger Ausbaupl{\"a}ne. Dazu wurden kasernenspezifische Geb{\"a}udeprofile entwickelt, die gemittelte spezifische Energiebedarfe und weitere Parameter zur Berechnung der Wand-, Fenster-, und Dachfl{\"a}che enthalten. Der spezifische W{\"a}rmebedarf kann durch einen Faktor an die Baualtersklasse angepasst werden.

Da Kasernen nur eine Bilanzgrenze besitzen, k{\"o}nnen zudem auch die Strombedarfe der einzelnen Geb{\"a}ude zusammengefasst werden. Damit lassen sich gleichzeitig dezentrale Batteriespeicher als Komponente des ESOMs ausschließen. Die Potenzialfl{\"a}chen von Erdw{\"a}rmepumpen k{\"o}nnen zusammengefasst werden, wobei Abstands- und Belastbarkeitsgrenzen eingehalten werden m{\"u}ssen. Kasernen verf{\"u}gen h{\"a}ufig {\"u}ber Bestandsw{\"a}rmenetze, die im ESOM gesondert ber{\"u}cksichtigt werden m{\"u}ssen.

This paper mainly focuses on analyzing this potential. Field tests were conducted to investigate the irrigation behavior and the storage effect of a storm water tree pit system using Perl hoses as irrigation elements over a period of two years. The rainfall, storage volumes, and soil moisture within the employed planting pit were measured. With the help of system modeling, the retention ability of the storm water tree pit system was analyzed. The available storage volume was sufficient to irrigate trees for several days. During the measurement period, about 15\% of the inflowing rainwater was fed to the root zone of the tree. With practical storage volumes of 200 to 300 m3/ha, a remarkable amount of water from heavy rainfall could be completely stored, thus significantly reducing the risk of flooding. The retention effect and irrigation behavior largely depend on the soil conditions and the technical possibilities of the equipment supplying the root area (in this case, Perl hoses).

Students receive an equivalent of 2.5 credit points (European Credit Transfer and Accumulation System - ECTS) for their engagement in the course and for publishing a short review article of at most 3 000 words in this periodical.

We encourage students to write their articles in English, but this is not mandatory. The reader will thus find a few articles in German language. To further encourage students practicing English writing, perfect grammar is not part of the assessment. We especially thank our students for working with LATEX on Overleaf, although LATEX is new to some of them. In this way, the editorial workload was reduced to a minimum. We also thank our students for sharing their work under the creative commons attribution licence (CC-BY). We appreciate their contribution to scientific information, being available to every person of the world, almost without barriers.

Its expansion is therefore important in order to achieve the climate targets. Repowering is an important element in the expansion of wind energy. On the one hand, it offers a solution for many wind turbines in Germany that are no longer subsidised due to their age. On the other hand, modern turbines are significantly more powerful and enable more efficient land utilisation. This article provides an overview of the most important aspects of onshore repowering. There is a lot to consider when repowering wind turbines. The legal situation for repowering aims to be improved through simplified authorisation procedures. Even though efforts are being made by the government, there is still room for improvement. The repowering potential is also dependent on the various distance regulations to residential buildings in the federal states. These regulations might also be improved in the future. Another aspect is the remuneration, which is now closer to market developments due to the market premium model. It is also subject to greater competition as a result of the tendering process. At the same time, interest rates and turbine prices have risen, which creates economic challenges for the operators of future wind farms. Last but not least, repowering also depends on public acceptance. This is also to be regulated by law in the future.}, language = {en} } @article{Weisser2024, author = {Weißer, Hannes}, title = {Relevance of Bird Strikes on Wind Turbines in Germany: A Review}, series = {Educational Journal of Renewable Energy Short Reviews}, journal = {Educational Journal of Renewable Energy Short Reviews}, doi = {10.25974/ren_rev_2024_13}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:836-opus-176500}, pages = {79 -- 84}, year = {2024}, abstract = {As Germany aims to increase its utilization of wind power, the potential threat to bird populations due to this expansion is a controversial issue.

Various challenges arise when it comes to upscaling. This article summarizes the technical challenges associated with upscaling wind turbines and presenting their problem-solving approaches and research trends based on other reviews. It was found that the most frequently cited challenges are related to individual components, such as rotor blades, drive train, generator, tower, and noise impact. For rotor blades, the challenges are increased flexibility, more aeroelastic vibrations, increased wear, interferences with radar and transportation difficulties. Proposed solutions include the use of carbon-fiber blades, prebending, novel paints, and for transportation, segmented rotor blades and on-site manufacturing. In the gearbox, torque increases, leading to higher weight and susceptibility to errors. As a result, the trend is moving towards gearless systems with permanent magnet synchronous generators. Transportation is the major issue with towers, which can be resolved with on-site manufacturing.

In the context of this paper, energy recovery in the outlet of wastewater treatment plants is examined using the specific example of the water wheel at the Warendorf central wastewater treatment plant. The "artificial" hydropower potential can be roughly estimated at up to 20 to 105 GWh/a , whereby this is largely dependent on the hydraulic gradient. The strong variance results, among other things, from the findings of the water wheel operation in Warendorf. The decisive aspect here is the differential factor, which describes the deviation between the theoretical and actual energy yield of the water wheel. The factor includes maintenance work, downtimes and insufficient inflows, which are associated with a loss of output. In the case study, the annual energy recovery amounts to approx. 2 \% of the annual electricity consumption of the wastewater treatment plant and can be estimated to 23,500 kWh (2022). In the context of the economic analysis, it can be seen that despite the "low" yield, economic operation is possible if the system is viewed as a long-term investment - payback period of the example is approx. 14,5 years.

The results show that the strength and form of the environmental impact depends on the specific location and type of plant. Tidal power plants have an impact on the habitats of marine animals and thus influence their behavior and population. In addition, the operation of tidal power plants changes the sediment distribution, causes a reduction in current velocities and a change in current direction in the surrounding area and leads to a change in wave height. The construction of the power plants is associated with noise, which primarily causes changes in the behavior of some species. Furthermore, the electromagnetic fields generated can also affect marine life.

Options that align with both financial and emission reduction and are robust to system changes are called "no-regret" options. Options sensitive to system changes are labeled as "potential-risk" options. There is a conflict between minimizing GHG emissions and financial costs.

It starts with an insight into the variety of different tidal power systems. With the help of a list from the European Marine Energy Center about currently used systems for tidal power plants, it quickly becomes apparent that two systems stand out. These are the vertical and horizontal turbines. The latter are particularly common, as they are used for both tidal stream and tidal range power plants. Determining the regions with high potential for tidal power is not always easy due to the many influencing factors. Influencing factors are, for example form and conditions of the seabed, topographical features of the coast or currents in the sea [1]. Therefore, each region must be considered separately. n this paper the focus is on the UK, the literature shows that the coastal regions around the UK provide about 50 TWh/year of the European tidal power potential. This is due to the location between the oceans and the geological conditions, which act as a channel for the tides. The two areas with high potential where planning and construction of tidal power plants is currently underway are in the north of Scotland and in the southwest of England in the Bristol Channel.}, language = {en} } @article{Goray2023, author = {Goray, Lars}, title = {Life cycle energy analysis and ecological impact of wind turbines - a comparison of life cycle assessments}, series = {Educational Journal of Renewable Energy Short Reviews}, journal = {Educational Journal of Renewable Energy Short Reviews}, doi = {10.25974/ren_rev_2023_02}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:836-opus-172613}, pages = {8 -- 15}, year = {2023}, abstract = {The use of wind power is rapidly expanding worldwide. It is important to examine the impact of wind turbines on the environment to see if they provide a net benefit and to identify potential for improving. Therefore life cycle assessments (LCA) of different wind turbine types are compared in this short review. The results are then shown side by side in tables for comparison. Overall the LCAs show that wind turbines compensate the required energy and emitted pollutants after approx. 6-16 months. The energy payback period (EPP) for 2 MW onshore wind turbines remained roughly the same since 2009 with approximately 7 months. Onshore wind turbines have a higher impact due to emissions but a shorter EPP than offshore wind turbines. The estimated service life of 20 years should be maximized to ensure a high energy yield ratio. The biggest impact on the environment results from the processes to provide the building material e.g. steel and cement. That impact could be reduced by 20 \% if recycled steel would be used. It is shown that wind power is one of the cleanest energy sources. But further investigations in material processing and recycling are important to improve the eco-balance of wind turbines.}, language = {en} } @article{Dresemann2023, author = {Dresemann, Oliver}, title = {Challenges for the construction of an underground hydroelectric power plant with electricity storage (UPSHP) in terms of public acceptance and technical aspects - A Summary}, series = {Educational Journal of Renewable Energy Short Reviews}, journal = {Educational Journal of Renewable Energy Short Reviews}, doi = {10.25974/ren_rev_2023_01}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:836-opus-172607}, pages = {3 -- 7}, year = {2023}, abstract = {For the increasingly important storage of renewably generated electricity, this review explains the construction of a surface and underground pumped storage power plant. The problems for the construction of an underground pumped storage power plant are further listed. These are geological, environmental and economic problems as well as a low acceptance by the population. The geological problems are concerns about leaching of minerals and heavy metals as well as the statics of the cavities. Mining companies in Germany are obligated to renaturalize the landscape areas again, which could be realised by a lake. Furthermore, care must be taken to ensure that the mine water does not come into contact with the groundwater. According to a survey by RISP on the subsequent use of the mine areas for an underground pumped storage power plant, the acceptance of the population is over 70 percent. The economic consideration concludes that the arbitrage profit for a difference between off-peak and peak of 10 €/MWh is about 2.7 M€/a and for 100 €/MWh about 27.3 M€/a. With investment costs of about 630 M€, despite the assumption of 100 €/MWh, more than 20 years are needed for an underground pumped storage power plant to be amortized. The acceptance could be increased by creating a lake as a recreation area as well as being used as an upper storage reservoir. Thus, the cost of renaturation decrease when combined with the creation of the storage basin. The problem of ground conditions can be solved by creating new cavities by means of tunnel boring at an inclination. For static safety as well as against leaching of minerals and heavy metals, the cavity walls can be sealed with reinforced concrete. The technology of underground pumped storage power plants can be used for better utilisation of renewable energies. This is especially in flat and densely populated regions a possibility to store energy, because the main part of the power plant is underground.}, language = {en} } @misc{OPUS4-17259, title = {Educational Journal of Renewable Energy Short Reviews}, editor = {Vennemann, Peter and Klemm, Christian}, doi = {10.25974/ren_rev_2023_00}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:836-opus-172599}, year = {2023}, abstract = {The Educational Journal of Renewable Energy Short Reviews (EduJRESR, formally published as `EGU Journal of Renewable Energy Short Reviews') is a teaching project rather than a regular scientific journal. To publish in this journal, it is a premise to take part in the master course wind power, hydro power and biomass usage at the department of Energy, Building Services and Environmental Engineering of the M{\"u}nster University of Applied Sciences. Students receive an equivalent of 2.5 credit points (European Credit Transfer and Accumulation System - ECTS) for their engagement in the course and for publishing a short review article of at most 3000 words in this periodical. The publication process closely mimics the typical publication procedure of a regular journal. The peer-review process, however, is conducted within the group of course-participants. Although being just an exercise, we think that publishing the outcome of this course in a citable manner is not only promoting the motivation of our students, but may also be a helpful source of introductory information for researchers and practitioners in the field of renewable energies. We encourage students to write their articles in English, but this is not mandatory. The reader will thus find a few articles in German language. To further encourage students practicing English writing, perfect grammar is not part of the assessment. We especially thank our students for working with LaTeX on Overleaf, although LaTeX is new to some of them. In this way, the editorial workload was reduced to a minimum. We also thank our students for sharing their work under the creative commons attribution licence (CC-BY). We appreciate their contribution to scientific information, being available to every person of the world, almost without barriers. We also thank the corresponding authors and publishers of the cited work, for granting permission to reuse graphics free of charge.

Dies gilt sowohl f{\"u}r den Bereich der Forschung und Entwicklung, als auch f{\"u}r die Industrie und Wirtschaft. So werden beispielsweise Modelle zur Planung und Optimierung von Energiesystemen umgesetzt. Eine Open Source Ver{\"o}ffentlichung ist in diesem Forschungsfeld besonders wichtig, um die {\"U}berpr{\"u}fbarkeit von Modellannahmen sowie der Vergleichbarkeit verschiedener Modellans{\"a}tze zu garantieren. Einer Open-Source Ver{\"o}ffentlichung stehen jedoch h{\"a}ufig die H{\"u}rden von hohem Fristendruck, fehlender Finanzierung und fehlendem Detailwissen der Publizierenden entgegen. Deshalb bleiben diese Softwareprodukte meist im Entwurfsstadium und sind daher schwierig wieder zu verwenden. Mithilfe des neu erarbeiteten Schritt-f{\"u}r-Schritt Leitfadens zur standardisierten Implementierung einer Open Source Software, wird die H{\"u}rde und der zeitliche Aufwand zur Standardisierung von Open Source Repositories weitestgehend reduziert. Hierbei wird f{\"u}r jedem Bestandteil des zu standardisierenden Repositorys eine umfassende Erkl{\"a}rung der {\"u}blichen Standards sowie eine Empfehlung f{\"u}r unterst{\"u}tzende Softwarel{\"o}sungen ausgesprochen. Der Leitfaden orientiert sich an den aus der ISO 12207 resultierenden Phasen des Softwarelebenszyklus und erm{\"o}glicht einen Einstieg zu jedem Entwicklungsstand der Software. Seine grafische Aufbereitung in Form eines Prozessablaufplans erleichtert die Einsch{\"a}tzung des individuellen Status der Standardisierung eines vorliegenden Open Source Projektes. Als Treiber der Standardisierung eines Open Source Projektes sind insbesondere die bessere Lesbarkeit, Wartbarkeit und Testbarkeit der standardisierten Open Source Software wichtig. Bei der Anwendung auf das bereits bestehende Open Source Projekt des Spreadsheet Energy System Model Genarators fiel auf, dass ein versp{\"a}teter Einstieg in ein systematisches Vorgehen (wie er mit dem Leitfaden dieser Arbeit gegeben wird) zu erheblichen Mehraufwand bei der Standardisierung f{\"u}hren kann. Dennoch konnten im Zuge der Umsetzung des erarbeiteten Leitfadens weitreichende Verbesserungen des Projektes vor dem Hintergrund der Standardisierung erreicht werden (z. B. Versionierung \& Wartbarkeit). Insgesamt l{\"a}sst sich festhalten, dass eine fr{\"u}hestm{\"o}gliche Standardisierung der Open Source Repositories durchgef{\"u}hrt werden sollte, um sp{\"a}tere Mehrarbeit zu vermeiden und die fr{\"u}hstm{\"o}gliche Wiederverwendbarkeit f{\"u}r Dritte zu gew{\"a}hrleisten.}, language = {de} } @article{BaeckerCloppenburgWingbermuehle2023, author = {B{\"a}cker, Carsten and Cloppenburg, Stefan and Wingberm{\"u}hle, Jonas}, title = {Thermisch notwendige Rohrleitungsl{\"a}nge vs. Stagnationsvermeidung: Thermisch getrennter Armaturenanschluss}, series = {Moderne Geb{\"a}udetechnik - Das Objektgesch{\"a}ft 2023}, volume = {2023}, journal = {Moderne Geb{\"a}udetechnik - Das Objektgesch{\"a}ft 2023}, number = {2023}, editor = {Huss, Christoph}, issn = {1436-686X}, pages = {41 -- 44}, year = {2023}, language = {de} } @article{KirchhoffRickmannBaeckeretal.2022, author = {Kirchhoff, Timo and Rickmann, Lars and B{\"a}cker, Carsten and Rickmann, Bernd}, title = {Fehler bei der Einregulierung gr{\"o}ßerer Warmwasser-Zirkulationssysteme}, series = {BTG-Almanach 2022}, volume = {2022}, journal = {BTG-Almanach 2022}, number = {April 2022}, pages = {41 -- 45}, year = {2022}, language = {de} } @article{BaeckerKemlerCloppenburg2022, author = {B{\"a}cker, Carsten and Kemler, Benedikt and Cloppenburg, Stefan}, title = {Reduzierung der Kaltwassertemperatur im Wohnungsbau}, series = {BTGA-Almanach 2022}, volume = {2022}, journal = {BTGA-Almanach 2022}, number = {April 2022}, pages = {12 -- 16}, year = {2022}, language = {de} } @book{BraunBaeckerBoettcheretal.2022, author = {Braun, Andreas and B{\"a}cker, Carsten and B{\"o}ttcher, Dirk and Klement, J{\"u}rgen and K{\"o}llisch, Jakob and Maibaum, Maik Benjamin and Petzolt, Ulrich and Politaj, Andreas and Tuschy, Stefan}, title = {Druckerh{\"o}hungsanlagen mit drehzahlgesteuerten Pumpen; Kommentar zu DIN 1988-500}, editor = {Zentralverband Sanit{\"a}r Heizung Klima,}, publisher = {Beuth Verlag GmbH}, address = {Berlin}, isbn = {978-3-410-30895-9}, publisher = {FH M{\"u}nster - University of Applied Sciences}, pages = {98}, year = {2022}, language = {de} } @article{RickmannMathysBaeckeretal.2023, author = {Rickmann, Lars and Mathys, Werner and B{\"a}cker, Carsten and Kirchhoff, Timo and Rickmann, Bernd}, title = {Zentrale Trinkwassererw{\"a}rmung - Energie sparen hat manchmal auch Grenzen}, series = {Moderne Geb{\"a}udetechnik.
