These efforts aim to transform urban areas, including neighborhoods, into conducive environments for walking, thereby realizing related benefits such as sustainable development. Extensive research has confirmed the role of the built environment in attracting and distributing pedestrian movement, with a significant portion highlighting the relationship between urban configuration and walkability. This study aims to determine the role of urban configuration components in enhancing walkability at the neighborhood scale, selecting the Valiasr neighborhood in Tehran due to its location in the city’s commercial center with a high volume of pedestrian traffic. For this purpose, after identifying spatial configuration components related to walkability – including accessibility, connectivity, and spatial arrangement components – key streets in the neighborhood's spatial configuration were identified using an initial analysis of spatial arrangement variables, followed by a survey of pedestrian volumes on selected streets. The evaluation of configuration components led to design recommendations in two layout patterns – grid and parallel block. The relationship between urban configuration and walkability, utilizing space syntax techniques, was identified after analyzing spatial arrangement variables in three different scenarios (existing condition and two proposed alternatives). The results indicate that accessibility components have the most significant impact on walkability in the Valiasr neighborhood. Following this, connectivity components were identified as influential in promoting pedestrian-oriented urbanism. Regarding spatial arrangement components, a comparison with prior research confirms that spatial elements do not operate independently of mixed-use and access to services and facilities. Instead, they play a role not in the formation of movement but in facilitating and directing it.","PeriodicalId":515235,"journal":{"name":"Urban Planning and Construction","volume":"16 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140971854","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}

{"title":"Double Skin Façades and IoT: A Review of Their Role in Building Energy Conservation and Natural Ventilation","authors":"Lachhman Das Khatri, Chalin Anakin, Anderson Noah, Sharma Prashansa, Ankon Lamia Tasnim","doi":"10.55121/upc.v2i1.140","DOIUrl":"https://doi.org/10.55121/upc.v2i1.140","url":null,"abstract":"Double skin façades and the Internet of Things (IoT) are pivotal in enhancing a structure’s energy efficiency and natural ventilation. Their impact, however, varies based on design size and geographical location, prompting an exploration of the nuanced interplay between IoT technology and energy savings across diverse building types and climates. The paper emphasizes crucial considerations in assessing IoT’s impact on energy efficiency, such as building’s category and location, whether a towering skyscraper, a modest apartment complex in arid New Mexico, or a structure in frigid Alaska. Investigating whether one type outperforms others and discerning global prevalence becomes essential. The exploration delves into design challenges posed by different building categories, addressing questions about the nature of a particular type presenting intricate obstacles to efficient design and whether regulatory requirements limit creative possibilities. Additionally, it examines the adaptability of doubleskin façades concerning materials without compromising performance. Enhancing energy efficiency and indoor thermal comfort involves manipulating materials for façade skins, introducing characteristics like fabrics for outer skins to allow airflow, and mitigating heat radiation from inner skins made of concrete, glass, or metal. This time lag contributes significantly to maintaining ideal indoor thermal conditions. The integration of IoT technology is pivotal, generating real-time data and notifying users of temperature differentials. This data-driven approach ensures optimal façade operation compared to conventional methods. In conclusion, the paper underscores the critical relationship between IoT technology and energy conservation in diverse building categories and climates, shedding light on challenges and opportunities associated with energy efficiency design. It advocates for the intelligent use of materials and IoT technology to realize substantial energy savings and improved indoor comfort. Exploring design challenges and considerations provides valuable insights for practitioners in the field.","PeriodicalId":515235,"journal":{"name":"Urban Planning and Construction","volume":"27 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139603065","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}
