Dadkhah","doi":"10.5755/j01.sace.26.1.24318","DOIUrl":"https://doi.org/10.5755/j01.sace.26.1.24318","url":null,"abstract":"Natural ventilation is application of natural drift power of wind. Wind can enter and exit buildings through the openings on facades. Hence, Form of facades can impact the air flow behaviour and consequently natural ventilation because they can change the pressure distribution on facades. Moreover, wind pressure difference between windward and leeward facades of buildings is the most important factor affecting natural ventilation. So, it is worthy to focus on facade details in order to enhance natural ventilation. Particularly, geometrical details of facades such as protrusions and indentations e.g. balconies can be considered effective elements on average pressure distribution on both windward and leeward facades, changing pressure difference between these facades. This difference can drive the air flow towards interior spaces significantly. Although this basic rule has been used by different researchers in order to increase natural ventilation buildings, the most research has been studied buildings with flat facades. Therefore, this study aims to investigate effects of balcony types on the natural ventilation. Three types of balcony are simulated and the wind pressure distribution on the windward and leeward facades are analysed. All these simulations are carried out for normally (perpendicular) and obliquely incident wind. This study is performed with Ansys Fluent 18 for all simulations. The results showed that balcony types can affect the pressure distribution on the windward and leeward facades of buildings, leading to the more or less pressure difference between these two facades. These results show that protrusion (protrusive balcony) can cause more complicated pattern of the wind pressure on facades than the others. Also, Re-entrant balcony causes the more pressure differences between the windward and leeward facades and enhances natural ventilation of buildings more considerably than the protrusive one.","PeriodicalId":36795,"journal":{"name":"Journal of Sustainable Architecture and Civil Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42550081","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}

Hence, they are among the monuments preserved by Turkish government’s related bodies, providing substantial grants for the preservation of these buildings. This study examines a 16th century historic tomb, Karyagdi Sultan Tomb, located in a congested area in Ankara, Turkey.  Although the tomb is at the hearth of the city and can be reached easily, it is not much known and visited by the community because of the unplanned constructions mostly used for commercial purposes surrounding and hiding the building.  The objective of this study is to investigate sustainability potentials and develop revitalization suggestions of the tomb and its neighbourhood appropriate to the environmental, cultural, and social values of the region by means of need analysis, field works, and interviews with the local community.  Overall, the study findings suggest that thanks to the appropriate sustainable solutions for the development of the neighbourhood and existing built heritage with regard to community, neighbourhood, and building context, visiting capacity and recognition of the tomb and the area can be increased substantially. Hence the research formulated several holistic sustainable preservation suggestions, and recommended further studies in order to realize the potentials of sustainability evident.","PeriodicalId":36795,"journal":{"name":"Journal of Sustainable Architecture and Civil Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44475800","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}

Realization of such tasks implies variation and adjustment of external shapes of buildings. Particular solutions depend on the chosen types of renewable energy sources, geographic location, and environmental conditions. The novelty of suggested solutions based on the principle of preliminary crowding of solar radiation, but against known analogs concentration of light by mirrors here used not for achieving of high amplitudes, but for diurnal equalization of an energy conversion process. Autodesk software products have been used for adjustment of conceptual schemes, including the models of buildings shaped as right circular, or elliptic, cylindrical reflectors. The basic evaluation carried out for the North Temperate Zone. Obtained results confirm that integration of local energy converters and appropriate modification of external shapes of buildings is more flexible and efficient than the application of centralized solar plants, because of their inexpensiveness and harmonization of beauty and energy efficiency. Application of static self-regulation of illuminance provides a high level of reliability and simplicity in exploitation. Suggested principle provides stepwise promotion of sustainability because it implies not only a passive economy of energy dissipation but also the equipment of architectural objects with inherent modules for active generation of renewable energy. Further development of such an energy sourcing schemes related also with the advancement of general safety (lowering of hazardous voltage) by the transition from common Electrical grid to adaptive local systems.","PeriodicalId":36795,"journal":{"name":"Journal of Sustainable Architecture and Civil Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46887058","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, developing countries give little or no concern to the practice of improving design outcomes using POEs. In Nigeria, buildings are rarely evaluated once they are handed over to the clients. This study explored the use of POE as a sustainable tool to evaluate building performance in developing countries with a case study of the Nigerian context. Using a systematic literature review, existing and current conceptual body of knowledge in peer-reviewed journals, electronic databases (Science Direct and Google Scholar), conference proceedings, and published articles were appraised; with specific focus to key issues of POE, such as; its definition, evolution, phases, levels, dimensions, application as a sustainable tool for building performance, and benefits. The study revealed that building occupants are a valuable source of information on building performance and POE serves the needs of the building users, and it is critical that the building should be evaluated from time to time to ensure that it is serving its intended purposes. Researchers also suggested that POE methods should be simple and building typology specific. It is suggested that POEs will be a vital tool in establishing best practices and lessons learned in delivering building performance evaluation in developing countries. Hence, the Education of professionals about the process of POE and the methods used, the education of clients by raising their awareness about the benefits of POE in sustaining building performance are suggested strategies for implementing POE in Nigeria and developing countries.","PeriodicalId":36795,"journal":{"name":"Journal of Sustainable Architecture and Civil Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45144361","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}
