This paper comprehensively reviews the energy, economic and environmental (3E) performance of prevalent passive and renewable solar systems, separately and combined, integrated into buildings. The advantages, limitations, and challenges associated with these systems are also thoroughly explored. Furthermore, many relevant recommendations to improve their overall performance and promote the sustainability of buildings are highlighted. The findings reveal that photovoltaic thermal technology provides the highest overall energy efficiency, ranging from 58% to 94%, amongst the compared solar systems. Economically and environmentally, photovoltaic, photovoltaic thermal and solar water heaters deliver excellent outcomes. Conversely, most solar-based passive strategies are energy-efficient and environmentally friendly, while some passive methods, such as Trombe wall and greening, are not cost-effective. However, the 3E efficiency of solar technologies largely depends on several factors, such as weather conditions, energy prices, capital costs and carbon content. Therefore, selecting appropriate energy systems is essential for constructing more sustainable, efficient and resilient buildings that benefit both the environment and occupants.</div></div>","PeriodicalId":56019,"journal":{"name":"Sustainable Energy Technologies and Assessments","volume":"72 ","pages":"Article 104079"},"PeriodicalIF":7.1,"publicationDate":"2024-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142653554","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Targeting these long-term fluctuations in day-ahead scheduling, this paper introduces a two-stage optimization methodology specifically designed for day-ahead scheduling with long-duration hydrogen storage systems (HSS) that effectively eliminates the need for scenario-reduction techniques by dividing the long-term scales into short-term ones. As the amount of stored hydrogen in the storage tank affects operational scheduling on consecutive days, the first stage introduces a new variable to represent variations in the stored hydrogen amount, effectively decoupling consecutive days. Subsequently, the second stage employs a developed active set algorithm. This algorithm adds hydrogen storage tank constraints to the objective function to ensure that the stored hydrogen amount does not exceed the tank’s capacity limits on any day. Using real-world data from South Australia State, simulation results validate the proposed algorithm’s effectiveness and demonstrate that employing large storage tanks within an HSS is viable for long-duration applications.</div></div>","PeriodicalId":56019,"journal":{"name":"Sustainable Energy Technologies and Assessments","volume":"72 ","pages":"Article 104072"},"PeriodicalIF":7.1,"publicationDate":"2024-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142653564","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this novel design, six copper-made fins are employed at a specific location on the waste heat pipe to boost the evaporation process, and a double-layer wick is employed over the glass to enhance the condensation process, which collectively leads to improved system performance. The performance optimization of the distillation system has been investigated to obtain the maximum mass of distilled water by varying the operating conditions of the input factors. Further, the Box-Behnken Design, Analysis of Variance, and Regression methods are applied to develop the empirical correlations between the input factors and a response parameter. The effects of various input factors on the response parameter are studied by response surface analysis through surface and contour plots. The experimental results revealed that the maximum value of the mass of the distilled water is obtained as 2.407 kg during 100 min of run at 321 °C of waste heat inlet temperature, 45° of glass angle, and 0.08 m of basin water height. Employing wick and copper fins in the distillation system has positively affected the yield of distilled water productionand increases the output from 2.054 kg to 2.407 kg with a 17.18 % improvement at the optimal conditions. It has been suggested that the highest waste heat inlet temperature level needs to be preferred to produce a large amount of distilled water. In contrast, the moderate levels of glass angle and basin water height provide the maximum output. The quadratic correlation is found to be in good agreement with the experimental values, with a maximum error of 12.03 %.
