However, some barriers such as high investment costs, complicated construction conditions, and long construction time have influenced the development of offshore wind power projects, thus, there is currently only one operational offshore wind power project. In this paper, the economic, technical, environmental efficiency of an offshore wind power project with a capacity of 30 MW in the Southern region of Vietnam is studied by using the Windpro program and the Retscreen software. The support policies of the government and obstacles in the investment process for offshore wind power projects are also analyzed. The research results show that the investment of case study offshore wind power project in the Southern region of Vietnam is economically feasible with the new Feed-in Tariff (FIT) price with the IRR of 18.6%, the NPV of $ 19,278,263, Benefit-Cost (B/C) number of 1.9 and the payback period of 8.3 years. However, the government needs to continue to improve support policies for offshore wind power in Vietnam, thus, incentivizing offshore wind farm projects can develop more in the next time.","PeriodicalId":48776,"journal":{"name":"Proceedings of the Institution of Civil Engineers-Energy","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2022-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84244716","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The thermal assessment of the so-called BATERRE building was analyzed against a Typical Building (TB) which represents the widest structure used in Moroccan rural classrooms and constructed with conventional materials. A TRNSYS based dynamic model was developed and validated using onsite monitoring measurements according to ASHRAE Guideline 14. Simulation results show that the BATERRE structure has a noticeable positive effect on indoor thermal comfort since its indoor air temperature remains stable while that of the TB classroom has higher oscillations. The hourly calculated indoor air temperature in BATERRE is greater by 3.6°C during winter and lower by 9.54°C during summer compared to the one in TB. Moreover, indoor thermal comfort analysis based on the ASHRAE Standard 55–2013 shows that BATERRE provides good indoor thermal comfort all year-round 63% of the time, while the corresponding indoor thermal comfort time part in TB is 32%. Furthermore, the annual thermal load of BATERRE is lower by 53% compared to that of TB.","PeriodicalId":48776,"journal":{"name":"Proceedings of the Institution of Civil Engineers-Energy","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2022-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76364228","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Many studies have been made on the potential of wave energy in the world and many wave energy converters have been developed. Although there is wave energy potential in Turkey, wave energy is hardly exploited. Main purpose of this study is to determine the most appropriate site and converter type for a wave energy power plant planned to be built in Turkey. For this purpose, a two-phased multi-criteria decision making (MCDM) structure is constructed. Analytic Network Process (ANP) and Fuzzy TOPSIS (Technique for Order Preference by Similarly to Ideal Solution) are selected as MCDM methods. Five cities located in the Black Sea coast which have high wave energy potential are selected as alternatives to the installation sites of the wave energy power plant. In the first phase, Sinop is determined as the most suitable wave energy power plant site by ANP. In the second phase, the most suitable wave energy converter to be installed in Sinop is determined as Oyster among the five alternatives by Fuzzy TOPSIS.","PeriodicalId":48776,"journal":{"name":"Proceedings of the Institution of Civil Engineers-Energy","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2022-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81177144","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The sensitivity of the solutions to future projections for domestic heating demands and climate change effects was explored. Simulations optimised the available energy supply, potential for storage, heat recovery and heat demand to minimise emissions at a scale that could be adopted in most UK towns. The approach may be able to deliver significant emissions reductions with more limited capital investment than more centralised renewable energy approaches. Results from two UK locations showed that integrated water–energy systems could theoretically reduce emissions by about 50%. Furthermore, the system could satisfy demand for about 70% of the time periods each year. Future scenarios were tested and it was found that the projected annual emissions reduction was similar across all scenarios, suggesting this would be a robust approach.","PeriodicalId":48776,"journal":{"name":"Proceedings of the Institution of Civil Engineers-Energy","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2022-01-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80090556","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As relatively recent technology, these designs are often high in cost, complex, and require specialist maintenance and materials. This is not viable for many communities in developing countries, which may subsequently remain reliant on fossil fuels. A remote river energy system has been designed to be built and maintained using minimal equipment, with components that can be readily obtained. A formal design process has been used with design review and feedback stages; design tools included Simulink modelling, FEA, CFD, nodal analysis and flume testing. Only a handful of components such as the turbine blades require specialist machining and maintenance. The results demonstrate how an effective water turbine with a 3kW output can be theoretically produced and maintained without an over-reliance on specialised components and tools, thereby producing a more economically viable water turbine for use in developing countries. Open source distribution of the design drawings will facilitate application of the design and improvements by other stakeholders. The design study presented here is a platform for prototype technology trials to further develop the concept.","PeriodicalId":48776,"journal":{"name":"Proceedings of the Institution of Civil Engineers-Energy","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2022-01-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80397565","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
