Densely populated cities characterize urbanized territories, and most public buildings fail to meet many of the new demands imposed by the pandemic and the modern lifestyle. The need to expand spaces has become imperative, although, at the same time, it is necessary to reduce land consumption and preserve green spaces. If we consider the existing heritage a resource, these problems could represent an opportunity to improve existing structures both from a technological and structural point of view. It is possible to effort a holistic approach by improving the energy impact of new buildings and the heritage seismic behaviour facing the problem in a multidisciplinary way. Starting from the “building on the built” philosophy, this paper presents a possible use of engineered wood, such as cross-laminated timber (CLT), to pursue this strategy. The proposal is the realization of volumetric additions to existing buildings without further land consumption. This type of intervention, mentioned as “parasitic architecture”, positively impacts urban regeneration strategies. The use of prefabricated timber components (CLT) endorses the speed of realization, reducing the interferences with the surroundings and improving the healthiness and safety of the environment.
人口密集的城市是城市化领土的特征,大多数公共建筑无法满足大流行病和现代生活方式带来的许多新要求。扩大空间的需求已经变得势在必行,尽管与此同时,减少土地消耗和保护绿色空间也是必要的。如果我们认为现有的遗产是一种资源,这些问题可能代表着从技术和结构的角度改善现有结构的机会。通过以多学科的方式改善新建筑的能源影响和传统地震行为来解决这个问题,这是可能的。从“建筑之上”的理念出发,本文提出了一种可能使用工程木材,如交叉层压木材(CLT)来实现这一策略。该提案是在不进一步消耗土地的情况下实现现有建筑的体量增加。这种类型的干预,被称为“寄生建筑”,对城市再生战略产生积极影响。预制木材组件(CLT)的使用加快了实现的速度,减少了对周围环境的干扰,提高了环境的健康和安全。

The purpose of this paper is to investigate service design and quality of restaurants in Bahrain and an understanding of its importance in the growing restaurant industry in Bahrain. This paper investigates the service design and restaurant design of restaurants in the Seef District, Bahrain using the DINESERV scale. A questionnaire was used to rate seven restaurants in the Seef District and the ratings are tabulated and a total mean out of 7 is calculated. The ratings for all of the seven restaurants were 5 and higher with minor differences between the participants ratings. This signifies that the level of service design and restaurant design quality in the Seef District is relatively high which subsequently leads to high customer satisfaction and high visiting rates. This brings to attention that there is a high level of awareness of the importance of service design and restaurant design in that area. Moreover, the final data brought to attention the gender, age and working status of the visiting participants. The data showed that most of the visitors were mid-20s, female students.
本文的目的是调查巴林餐厅的服务设计和质量,并了解其在巴林不断增长的餐饮业中的重要性。本文采用DINESERV量表对巴林塞夫区餐厅的服务设计和餐厅设计进行了调查。我们使用问卷对Seef区的七家餐厅进行评分,并将评分制成表格,计算出总分7分的总平均值。这七家餐厅的评分都在5分以上,参与者之间的评分差异很小。这说明Seef区的服务设计水平和餐厅设计质量都比较高,因此顾客的满意度和到访率也很高。这引起了人们对该领域服务设计和餐厅设计重要性的高度认识。此外,最后的数据引起了人们对访问参与者的性别、年龄和工作状况的关注。数据显示,大多数访客都是25岁左右的女学生。

Poor communication between architects and end-users of the built environment has been implicated as the main barrier to improving design quality and end-user satisfaction. User-centered design (UCD) is an important approach to communication and reaching the end-user affective state. This study aims to develop a new integrated approach for achieving an enhanced user-centered design. UCD is a process of three stages: understanding end-user needs, creating design solutions, and evaluating designs. The new approach is concerned with the built environment’s impact on the user’s affective state in the early design stage. The mobile brain/heart imaging technology is used to record users’ electroencephalogram (EEG) and heart rate variability (HRV) while they navigate the design proposal in non-immersive virtual reality (VR). In this context, the Farsi Lecture Hall in the Faculty of Engineering at Alexandria University was selected to be redesigned. The adopted methodology is based on understanding the needs of architecture students (end-users) through questionnaires and evidence-based design (EBD). Six design proposals were proposed and presented with still images. First, the students were asked to rate each proposal on a 5-point Likert scale. Then they were asked to select the best visualization technique, and the majority chose the 360-panorama. At last, the students sat in Farsi Hall for 3 minutes navigating the best proposal panorama on a full HD laptop screen wearing EEG headband that records EEG and HRV. The SAM test and 5-point Likert stress scale were recorded and compared to EEG and HRV results. The findings of this study show that there is a significant relationship between SAM ratings, EEG, and HRV. Furthermore, 360-panorama is an effective visualization tool for presenting design. Finally, involving mobile brain/heart imaging to induce the end-user affective state while navigating design proposals in VR could enhance design quality and end-user satisfaction.
建筑师和建筑环境的最终用户之间缺乏沟通已经被认为是提高设计质量和最终用户满意度的主要障碍。以用户为中心的设计(UCD)是沟通和达到最终用户情感状态的重要途径。本研究旨在开发一种新的集成方法,以实现增强的以用户为中心的设计。UCD是一个分为三个阶段的过程:理解最终用户需求、创建设计解决方案和评估设计。新方法关注建筑环境对早期设计阶段用户情感状态的影响。移动脑/心脏成像技术用于记录用户在非沉浸式虚拟现实(VR)中浏览设计方案时的脑电图(EEG)和心率变异性(HRV)。在这种情况下,亚历山大大学工程学院的波斯语演讲厅被选中进行重新设计。所采用的方法是基于通过问卷调查和循证设计(EBD)了解建筑学生(最终用户)的需求。提出了六个设计方案,并以静态图像呈现。首先,学生们被要求以5分的李克特量表对每个提案进行评分。然后他们被要求选择最好的可视化技术,大多数人选择了360全景。最后,学生们在波斯语厅坐了3分钟,戴着脑电图头带,在全高清笔记本电脑屏幕上浏览最佳求婚全景图,记录脑电图和心率。记录SAM测试和5点Likert应激量表,并与EEG和HRV结果进行比较。本研究的结果表明,SAM评分、EEG和HRV之间存在显著的关系。此外,360度全景是展示设计的有效可视化工具。最后,利用移动脑/心成像来诱导终端用户在VR中导航设计方案时的情感状态,可以提高设计质量和终端用户满意度。

The environmental durability of earthen materials is among the main factors that limit their widespread acceptance in the contemporary building sector. This study assesses the performances of compressed earth blocks (CEBs) before and after exposure to the wetting–drying (WD) cycles and high temperature. The CEBs were produced from kaolinite-rich earth material stabilized with lime-rich residue (5%–25%) or the lime substituted with rice husk ash, lime:ash (20:0%–12:8%) or cement (4%–8%), with respect to the mass of dry earth. The CEBs were cured for 28–45 days and at the ambient temperature of a laboratory of 30±5°C and the moisture of production, necessary for the reactivity of the binders and improvement of the performances of CEBs. The CEBs were dried before testing their initial compressive strength. Their compressive strength was also tested after exposure to 12 cycles of wetting in water for 6 hours at 30±5°C and drying in the oven for 42 hours at 70±5°C. Additionally, it was tested after exposure to the elevated temperature of 150–600°C. After exposure to the WD cycles, the compressive strength of CEBs relatively increased, by up to 49% (4.6 to 6.8 MPa) for CEBs stabilized with lime (15%) and by up to 40% (4.4 to 6.2 MPa) with lime:ash (20:0%), with respect to their strength before the WD cycles. The maximum increase of the strength was observed for CEBs containing a higher amount of lime, related to the reaction of excess lime which resulted in the formation of more cementitious products and improvement of the strength of CEBs. Nevertheless, the compressive strength decreased by 55% (12.5 to 5.5 MPa) for the CEBs stabilized with cement (4%), resulting from the degradation of the initial cementitious products. However, the strength increased by up to 58% (4.2 to 6.6 MPa) for the CEBs stabilized with cement (8%) after exposure to 600°C. This implies that the stabilization of CEBs with lime-rich binder is more resilient to the WD cycles than cement. It also shows that the cement stabilized CEBs would at least retain their strength after exposure to high temperature.
土材料的环境耐久性是限制其在当代建筑领域广泛接受的主要因素之一。本文研究了压缩土块(ceb)在干湿循环和高温作用前后的性能。根据干土的质量,用富石灰渣(5% ~ 25%)稳定富高岭石土材料或用稻壳灰、石灰:灰(20:0% ~ 12:8%)或水泥(4% ~ 8%)代替石灰制备ceb。ceb在30±5°C的实验室环境温度和生产湿度下固化28-45天,这是粘合剂反应性和ceb性能改善所必需的。在测试其初始抗压强度之前,将ceb干燥。在30±5°C的水中湿化6小时,在70±5°C的烘箱中干燥42小时,经过12个循环后,测试了它们的抗压强度。另外,在150-600°C的高温下进行测试。经过WD循环后,ceb的抗压强度相对于WD循环前的强度提高了49% (4.6 - 6.8 MPa),石灰(15%)稳定的ceb的抗压强度提高了49% (4.4 - 6.2 MPa),石灰:灰分(20:0%)稳定的ceb的抗压强度提高了40% (4.4 - 6.2 MPa)。石灰掺入量越高,ceb的强度提高幅度越大,这与过量石灰的反应导致ceb的胶凝产物越多,强度提高有关。然而,由于初始胶凝产物的降解,水泥稳定的ceb(4%)的抗压强度下降了55% (12.5 ~ 5.5 MPa)。然而,暴露于600°C后,水泥稳定的ceb(8%)强度增加了58%(4.2至6.6 MPa)。这表明,与水泥相比,富石灰胶结剂的ceb对WD循环的稳定性更强。结果表明,水泥稳定的ceb在高温下至少能保持其强度。

MONOTONY OF PARTS OF CONTEMPORARY ARCHITECTURE: THE ABSENCE OF SMALL DETAILS AND SEPARATIONS 当代建筑部分的单调:缺乏小细节和分离
Pub Date : 2022-09-20 DOI: 10.2495/arc220151
U. Dietrich
In contemporary architecture, a trend can be observed that buildings have a simple rectangular form and façades are composed of a few large elements, all together leading to a monotonous look. Following a proposed list of good design criteria, representative examples of a historical building (from 1900) and a contemporary one are analyzed and confronted. Based on that design criteria an endeavour to criticise certain trends in contemporary architecture can be implemented. To bring the question what makes a façade aesthetic to a more objective basis, the perception mechanism of the human eye is presented. Because of its spherical form, it delivers a sharp vision only in an exceedingly small angle range. Consequently, the eye moves quickly over the object in view producing several sharp spots that are finally completed to a sharp image by the brain. This process can run smoothly if there, where the next eye movement (saccade) strikes on the object, is a new, perceptible element located – the eye’s movement is guided, the object is perceived positively and aesthetically. As a precondition, a particularly high number of small-sized elements and few principles of order, what confirms a good part of the list of design criteria, are needed. Based on this, arguments why parts of contemporary architecture may be perceived as monotonous, partly out of human scale and not really aesthetic are formulated as well as conclusions what is missing. In order to involve (future) professionals, a master’s course for students of architecture at HafenCity University Hamburg is presented. Architectural ensembles were selected and drawings of the eye’s movement scanning the shown objects generated. The students’ analysis confirmed well a connection between a good guidance of the eye’s movement and a positive, aesthetical perception. Finally, reasons why there is contradiction between the awareness of good design and the practical outcome are sketched.
在当代建筑中,可以观察到一种趋势,即建筑物具有简单的矩形形式,立面由几个大元素组成,所有这些元素一起导致单调的外观。根据提出的良好设计标准清单,对历史建筑(1900年)和当代建筑的代表性例子进行了分析和面对。基于这一设计标准,可以对当代建筑的某些趋势进行批评。为了使是什么构成了一种更客观的审美,提出了人眼的感知机制。由于它是球形的,所以只能在很小的角度范围内提供清晰的视野。因此,眼睛在视野中的物体上快速移动,产生几个尖锐的斑点,最终由大脑完成清晰的图像。如果下一个眼球运动(扫视)击中物体的地方有一个新的、可感知的元素,这个过程可以顺利进行——眼球的运动被引导,物体被积极地、美学地感知。作为先决条件,需要特别多的小型元素和少量的顺序原则,以确认设计标准列表中的大部分内容。在此基础上,讨论了为什么部分当代建筑可能被认为是单调的,部分超出了人类的尺度,而不是真正的美学,并得出了缺失的结论。为了让(未来的)专业人士参与进来,汉堡港城市大学为建筑专业的学生开设了一门硕士课程。选择建筑整体,并生成眼睛扫描所显示对象的运动图。学生们的分析很好地证实了眼睛运动的良好引导与积极的审美感知之间的联系。最后,简述了优秀设计意识与实践成果之间存在矛盾的原因。

URBAN FABRICS OF HOUSING FORMS AND ITS IMPACT ON HUMAN BEHAVIOR 住房形式的城市结构及其对人类行为的影响
Pub Date : 2022-09-20 DOI: 10.2495/arc220071

An individual’s psychological life and their incorporation with the built environment have a remarkable relationship with urban space syntax. The scarcity of positive communication between humans and place-making is considered the core problem. This phenomenon occurs when urban designers ignore the role of humanity during the design process without taking into consideration its influence on the development of urban spaces. An individual’s well-being and their quality of life are affected by the degree of residential satisfaction. Factors contributing to residential satisfaction include: (1) physical factors that could be determined in the availability of parks and facilities in the community; (2) social factors that could be determined in the feeling of belonging to a community; and (3) personal factors that could be determined in people’s duration of residence and homeownership. The paper aims to examine the relations between human behavior and urban housing form through investigating the human behavior associated with the physical environment and determine the factors affecting it. The paper’s assumption is that improving the quality of the space syntax will increase the residents’ belonging to their built environment, in addition to enhancing their residential satisfaction. Increasing levels of sense of community, sense of belonging, and sense of place could achieve residential satisfaction. To further explain the relation between human behavior and physical built environment regarding sense of community, sense of belonging, and sense of place, the study applies its findings to a selected study area in the city of Alexandria, Egypt. The results revealed strong correlation between physical built environment and human behavior.
个体的心理生活及其与建筑环境的结合与城市空间句法有着显著的关系。人们与场所营造之间缺乏积极的沟通被认为是核心问题。这种现象是由于城市设计师在设计过程中忽视了人文因素的作用,没有考虑到人文因素对城市空间发展的影响。一个人的幸福和他们的生活质量受到居住满意度的影响。影响居住满意度的因素包括:(1)物理因素,可以通过社区内公园和设施的可用性来确定;(2)社区归属感所决定的社会因素;(3)居住年限和房屋所有权等个人因素。本文旨在通过对与自然环境相关的人类行为的调查,来考察人类行为与城市住宅形态之间的关系,并确定影响人类行为的因素。本文的假设是,提高空间句法的质量将增加居民对其建筑环境的归属感,并提高他们的居住满意度。提高社区意识、归属感和地方感可以实现居住满意度。为了进一步解释人类行为与实体建筑环境在社区意识、归属感和地方感方面的关系,该研究将其研究结果应用于埃及亚历山大市的一个选定的研究区域。结果显示,物理建筑环境与人类行为之间存在很强的相关性。

This phenomenon occurs when urban designers ignore the role of humanity during the design process without taking into consideration its influence on the development of urban spaces. An individual’s well-being and their quality of life are affected by the degree of residential satisfaction. Factors contributing to residential satisfaction include: (1) physical factors that could be determined in the availability of parks and facilities in the community; (2) social factors that could be determined in the feeling of belonging to a community; and (3) personal factors that could be determined in people’s duration of residence and homeownership. The paper aims to examine the relations between human behavior and urban housing form through investigating the human behavior associated with the physical environment and determine the factors affecting it. The paper’s assumption is that improving the quality of the space syntax will increase the residents’ belonging to their built environment, in addition to enhancing their residential satisfaction. Increasing levels of sense of community, sense of belonging, and sense of place could achieve residential satisfaction. To further explain the relation between human behavior and physical built environment regarding sense of community, sense of belonging, and sense of place, the study applies its findings to a selected study area in the city of Alexandria, Egypt. The results revealed strong correlation between physical built environment and human behavior.","PeriodicalId":23773,"journal":{"name":"WIT Transactions on the Built Environment","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82993782","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}

In the last decade, biophilic design under the concept of creating strong connections between nature and manmade environments have spread significantly. Because of the rapidly increasing environmental crises and climate change phenomena globally. Consequently, biophilic design has become associated with sustainable applications, the question this research discusses is if this approach contributes to achieve the aspects of sustainability, under the umbrella of the UN Sustainable Development Goals (SDGs). This study will investigate biophilic approach contribution to sustainable design through defining aspects of nature that most influence human satisfaction of built environment. Aligned with the European Commission (2015) series actions titled “nature-based solutions” that are inspired by nature systems. During the COVID-19 lockdown, humans had minimal interaction with nature, and access to green public spaces, at the same time, an increasing interest to integrate nature in design, reducing humans impact on nature were recognized in the contemporary built environment. The study adopts William Browning’s (2014) “14 Patterns of Biophilic Design” framework, that lays out a series of tools experiencing science and nature contribution for promising opportunities creating sustainable built environment design applications. In addition to identifying and analysing the current practices for biophilic design in the built environment and its’ impacts on nature and human wellbeing. The results conduct design strategies, and guidelines that integrate biophilic approach as a base, within the 14 patterns framework for better practices creating innovative and responsible built environment. © 2022 WIT Press.
在过去的十年里,在自然和人造环境之间建立紧密联系的概念下,亲生物设计得到了显著的传播。由于全球环境危机和气候变化现象的迅速增加。因此,亲生物设计已经与可持续应用联系在一起,本研究讨论的问题是,在联合国可持续发展目标(SDGs)的保护下,这种方法是否有助于实现可持续性方面。本研究将通过定义最能影响人类对建筑环境满意度的自然方面,探讨亲生物方法对可持续设计的贡献。与欧盟委员会(2015)系列行动一致,这些行动的灵感来自于自然系统,名为“基于自然的解决方案”。在2019冠状病毒病封锁期间,人类与自然的互动很少,无法进入绿色公共空间,同时,在当代建筑环境中,人们越来越有兴趣将自然融入设计,减少人类对自然的影响。该研究采用了威廉·勃朗宁(2014)的“亲生物设计的14种模式”框架,该框架列出了一系列体验科学和自然贡献的工具,为创造可持续建筑环境设计应用提供了有希望的机会。除了识别和分析当前建筑环境中亲生物设计的实践及其对自然和人类福祉的影响之外。结果指导设计策略和指导方针,将亲生物方法作为基础,在14种模式框架内为更好的实践创造创新和负责任的建筑环境。©2022 WIT出版社。

A recent sustainability-based economic model, the Circular Economy, is examined as a catalyst for a potential new retail model focused on an integrated sustainable system providing residential building and renovation products sales. The premise of the Circular Economy is the argument of utilizing resources continuously by extracting the maximum value from them, then recovering and regenerating products and materials at the end of each service life. The research presents a qualitative study of the Circular Economy concept as an innovation outgrowth for the built environment and retailing facilities. The work proves the Circular Economy theory’s necessity as applied to the retail industry, providing a new programmatic retail-based concept with a practical development as an architectural design demonstration project. This project demonstrates how through new retail programmatic synergies, the Circular Economy would be the basis for a new retail model. The application is shown through an urban redevelopment proposal of a former industrial building in a declining North American city that demonstrates Circular Economy issues in the site selection and building design.

DESIGNING AN URBAN FOOD SYSTEM FOR ACHIEVING CIRCULAR ECONOMY TARGETS: A CONCEPTUAL MODEL 设计一个实现循环经济目标的城市食品系统:一个概念模型
Pub Date : 2022-09-20 DOI: 10.2495/arc220021

In exploring the strategies for reaching sustainable development goals (SDGs), the importance of circular development has been greatly recognized in sustainable studies and practices. Regarding applying the circularity concept at city scales, the United Nations Economic Commission for Europe emphasizes that transitioning to a circular economy will help city leaders achieve SDGs and other global objectives of climate actions. The food sector is a significant contributor to climate change, biodiversity loss, and land degradation, which can all be resolved via circular economy solutions. There is an urgent need for our current dominant global food systems (FS) to change due to the multiple environmental influences across the whole food value chain (FVC). This calls for the implementation of circular economy principles in FS, especially for urban systems, which account for most of the world’s food consumption, loss, and waste; and for most of the world’s greenhouse gas emissions. Applying circular economy principles to each stage of FVC offers various opportunities to address FS issues as they enable each actor to identify the parts they can participate in FS transition. Secondly, circular economy strategies such as localizing food chains, food wastes reduction, and reusing raw materials offer solutions to FS sustainability, connecting FS sustainability transition with the transformation of industrial food metabolism from linear to circular. Since cities play a critical role in sustainable transitions from linear to circular, pursuing a circular urban food system (UFS) benefits circular urban metabolism too. To aid the implementation and promotion of circular economy in FS and cities, this study proposes a conceptual model of designing UFS for achieving circular economy targets.
在探索实现可持续发展目标(sdg)的战略过程中,循环发展的重要性在可持续研究和实践中得到了极大的认识。关于在城市尺度上应用循环概念,联合国欧洲经济委员会强调,向循环经济过渡将有助于城市领导人实现可持续发展目标和其他全球气候行动目标。粮食部门是造成气候变化、生物多样性丧失和土地退化的重要因素,这些问题都可以通过循环经济解决方案得到解决。由于整个食品价值链(FVC)的多重环境影响,我们迫切需要改变目前占主导地位的全球食品系统(FS)。这要求在粮食系统中实施循环经济原则,特别是在城市系统中,城市系统占世界粮食消费、损失和浪费的大部分;对世界上大部分的温室气体排放也是如此。将循环经济原则应用于FVC的每个阶段,为解决FS问题提供了各种机会,因为它们使每个参与者能够确定他们可以参与FS过渡的部分。其次,食物链本地化、减少食物垃圾、原材料再利用等循环经济战略为FS的可持续发展提供了解决方案,将FS的可持续发展转型与工业食物代谢从线性到循环的转变联系起来。由于城市在从线性到循环的可持续转型中发挥着关键作用,追求循环城市粮食系统(UFS)也有利于循环城市代谢。为了帮助循环经济在城市和城市的实施和推广,本研究提出了一个设计城市循环经济目标的概念模型。
