In recent years there has been a growing awareness in energy-efficient building design and operation of the building stock. Dynamic envelope/window systems have potential to optimize the performance of the building, between airing, solar heat gain and daylight admission. However, higher thermal resistance glazing implies a reduction of solar transmittance. A typical street canyon in Portugal was used for the present study. Three different room ratios and two types of windows at two different floors were used for comparison. Different simulation tools were used during this study. To be comparable with other studies several ratios were present, as the window/wall, the glazing/wall ratios, the window/floor and the glazing/floor ratios as well as the window opening area. This paper presents the obtained airflow and solar gains on both heating and cooling season in addition to the level of daylight factor. It was found that specific adaptive actions to improve indoor environmental quality and reduce the need of energy consumption are needed.","PeriodicalId":177785,"journal":{"name":"WEENTECH Proceedings in Energy","volume":"83 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116000494","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}

Consequences are for example emissions of greenhouse gases, particulates, carbon monoxide and nitrogen oxides. This is of great concern for the environment, climate change, and human health. This study reviews scientific publications about sustainable development of the road transport sector, published 2005-2018. The aim of the study is to investigate if there are differences in the measures and strategies presented in the publications depending on the geographical areas studied, and to analyse if there are differences depending on year of publication. The authors analysed to what extent local conditions influence the choice of proposed measures and strategies. A system perspective was applied in order to include measures related to the whole life cycle of the road transport, as well as other sectors, which influence or are influenced by the transport sector. A literature review was performed using the search-engine Web of Science. Results show that important local conditions that may influence the research focus within the area of sustainable development of the road transport sector are for example: energy supply security (e.g. availability of biomass and renewable electricity, as well as access to domestic fossil fuel resources), possibilities for developing infrastructure for biofuel supply and charging of electric vehicles, political priorities and approaches, and traditions.","PeriodicalId":177785,"journal":{"name":"WEENTECH Proceedings in Energy","volume":"76 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133343154","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}

Chow","doi":"10.32438/WPE.0418","DOIUrl":"https://doi.org/10.32438/WPE.0418","url":null,"abstract":"Tri-generation system combines the supply of electric power, heating and cooling energy into one single system. Compared to the separated energy generation systems, the advantages lie in its higher efficiency, reliability and flexibility, as well as the reduced pollutant emissions. Yet the mismatch in system electricity and thermal demands often downgrades its effectiveness and economic merits. At this end, the adoption of thermal energy storage can be a practical means of improvement. Among the various choices, the finned latent heat storage using phase change material is distinct advantage owing to its high energy density. On the other hand, the finned latent heat storage design requires a detailed analysis of the heat transfer process. In this paper, our numerical model is introduced for use in simulating the associated complex heat transfer processes. The accuracy of the numerical model has been verified making use of the published experimental data available from the literature. Furthermore, our follow-up parametric study shows that the increase of fin thickness will improve the heat transfer performance for a given design configuration and the better heat transfer can be achieved with the reduction in fin length and fin spacing as well.","PeriodicalId":177785,"journal":{"name":"WEENTECH Proceedings in Energy","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116741310","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}

To improve the supervision strategies for meeting a better supervision and treatment effect, this paper will evaluate the effect of the cooperative supervision on air pollution and control in Beijing-Tianjin-Hebei and give several advices on the improvement of existing supervision method through results analyzation. Firstly, a comprehensive evaluation criteria system is established. Then a novel method of determining weight is firstly proposed in this paper, -fuzzy measure and AHP are used for determining weights which can not only consider the correlation among criteria but also take care of the will of the decision-makers. Finally, we obtain the evaluation ranking results by Fuzzy comprehensive evaluation combined with Cloud model and several advice is proposed. In general, the model can provide reference for monitoring and evaluating the effect of supervision on air pollution prevention and control in other regions and the results analysis provide a great reference to the decision makers to optimize the cooperative supervision in Beijing-Tianjin-Hebei.","PeriodicalId":177785,"journal":{"name":"WEENTECH Proceedings in Energy","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125100560","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}

Rashid","doi":"10.32438/WPE.10918","DOIUrl":"https://doi.org/10.32438/WPE.10918","url":null,"abstract":"During the monsoon season the water distribution systems in the cities of Bangladesh, a developing country, has its distribution pipelines compromised due to water intrusion. This produces outbreaks of waterborne diseases. An easy solution is simply boiling the water before drinking. Unfortunately, this practice is limited due to fuel shortage or added fuel expense incurred. The affected population ends up using simple filters that is not effective in removing disease causing microorganisms from water. Every household in Bangladesh eats rice as their main staple and it is cooked twice a day for lunch and dinner. The method used is boiling and then simmering rice in a pot. The rice cooking process generates water vapor, which we are trapping and condensing by a stacked pot water heater/disinfector in a very simple way to utilize the latent heat to heat water to a required temperature and duration for disinfection. The efficacy of the process was evaluated in a controlled experimental program. The results indicated that our process would heat the water to temperatures that would inactivate pathogenic bacteria, viruses, and protozoa by raising the water temperature to 76.6 ±0.9oC, utilizing the latent heat generated from rice cooking. Further, if one wants to bring the water to rolling boiling, it requires ~ 3.0 minutes of additional direct heating after preheating with our system. This additional heating would require a normal expenditure of LPG of 0.073kg to bring to boil 10 L of water after preheating; whereas direct heating to bring 10 L of water to boil from an ambient temperature of 23.0oCwould require 0.24 Kg of LPG. We feel that this system will go a long way to address this public health crisis faced every year in Bangladesh and to address the safe water crisis faced by the million plus Rohyangya refugees from Burma living in makeshift camps in Bangladesh. In addition, our system can be utilized in other developing countries to provide safe drinking water.","PeriodicalId":177785,"journal":{"name":"WEENTECH Proceedings in Energy","volume":"761 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123881742","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}

It is of great concern for government to maintain the effectiveness of monitoring effect so that the prevention and control of air pollution is guaranteed, further the air condition of Jing-Jin-Ji area would be improved. For the purpose of evaluating the synergistic monitoring effectiveness, a evaluation index system for air pollution prevention and control in Jing-Jin-Ji area should be established so as to conduct the evaluation process in a scientific and rational way. By analyzing the general principles of setting up an index system, we summarize six principles for the establishment which includes comprehensiveness, purpose, simplicity, independence, hierarchy and feasibility. On the basis of the principles mentioned above, we further break the evaluation problem into 4 targets and 23 indexes so that the index system is established. Through the index system we proposed, government and enterprises can effectively evaluate the synergistic monitoring effect of air pollution prevention and control in Jing-Jin-Ji area so that scholars and supervisors are capable to further study relative problems.","PeriodicalId":177785,"journal":{"name":"WEENTECH Proceedings in Energy","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122035138","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}
