Despite their high initial cost, these materials promise to elevate the quality of residential performance and thermal comfort over time. There were numerous studies that addressed this subject, but the vast majority of them approached research and evaluation with an investigative and analytical mindset. There aren't many studies that look at the precise computer evaluation of the usage of insulating nanotechnologies in architecture, which shows that there is still a research deficit in the field. The objective of the research was to focus on computational capabilities to estimate the percentage of improvement in the thermal performance of a residential apartment in Mosul using local materials as a baseline case and compare it to expanded polystyrene second, followed by Nano insulation materials third and fourth, respectively. The results obtained show that, in each sample in the prior situations, the required thermal load decreased by rates of 45.8%, 22.8%, and 28.9% respectively, when compared to the base case. This demonstrates how crucial the nanomaterial's insulating properties are to raising thermal efficiency. Further, our findings demonstrated that the application of nanotechnology, particularly nano-vacuum insulation panels, can increase the number of days of thermal comfort in a residential apartment while concurrently reducing the peak heating and cooling requirements.","PeriodicalId":13902,"journal":{"name":"International Journal of Design & Nature and Ecodynamics","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135991044","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, with the impending depletion of fossil fuels, an urgent transition towards sustainable and environmentally friendly renewable energy sources is necessary for electricity generation. The Hybrid Renewable Energy System (HRES), which amalgamates various renewable energy sources, offers a promising solution. This study investigates the economic viability of a photovoltaic (PV)-wind turbine hybrid microgrid system for off-grid electrification in five distinct cities in Papua, Indonesia. A simulation of the hybrid system was conducted using the Hybrid Optimization Model for Electric Renewable (HOMER) application, leveraging local solar and wind resource data. The simulation results indicated that Waropen city yielded the most optimal PV-wind turbine hybrid system, exhibiting the lowest Net Present Cost (NPC) of Rp397,591,000.00 and Cost of Energy (COE) of Rp 5,513.37/kWh. This system was capable of generating 9,098 kWh/year of electricity. Consequently, the proposed PV-wind turbine hybrid microgrid system emerges as an economically feasible solution for off-grid electrification in Papua, underscoring the potential of renewable energy sources in addressing the global energy crisis.","PeriodicalId":13902,"journal":{"name":"International Journal of Design & Nature and Ecodynamics","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135989958","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
