The paper presents the main findings of research focusing on hardcore brownfield sites in the post-industrial area of Drapetsona along Piraeus Port in Greece. The research took place from March 2022 to May 2022. The selected case study includes a derelict site of 640.000 m2 including both buildings and vacant land. Given the opening up of the economy of Piraeus to foreign investors, authors explore the potential of the site in the era of globalization with the view to put in the forefront community’s outlook. Research includes literature review and field work. It is important to mention that this research provides original material for an issue that is not fully covered in existing literature; the contemporary situation of the former Chemicals and Fertilizers Factory in Drapetsona, focusing on key-obstacles and positive attributes. Field work includes quantitative and qualitative methods as well as direct observations. Authors used SPSS statistical software to process the selected data. Authors have also organized a workshop together with members of the local community (1st Technical High School EPAL Drapetsonas) to understand residents’ perspective on hardcore brownfield redevelopment. Findings from the workshop are presented in combination with quantitative data and results from direct observations. The paper concludes with recommendations for future application.

This study analyzed the possible use of a residue from the steel industry, blast furnace dust, as aggregate in asphalt mixtures for pavements, as a possible solution to the problems of generation and accumulation of industrial waste in the production of steel, as well as the exploitation of non-renewable materials for infrastructure construction. In the production of steel, solid residues such as slag and blast furnace dust are generated, which become industrial waste. Another found issue in pavement construction is the exploitation and use of stone materials are necessary. Two test states were selected to achieve the established objective where blast furnace dust totally (100%) or partially (50%) replaced the conventional fine aggregate in an asphalt mixture at the laboratory. The applied methodology consisted of four stages: establishing the properties of the materials, determining the composition of the blast furnace dust, designing each of the mixtures using the Ramcodes methodology, and finally performing performance tests such as dynamic modulus and fatigue laws. The results show an acceptable behavior of the blast furnace dust and allow to define that the use of this residue is technically feasible in manufacturing asphalt mixtures for pavements.

This paper analyses the presence of sustainable elements in one of the most representative surviving examples of vernacular residential architecture from the Ottoman period, located in Bosnia and Herzegovina. The focus is on the significance of vernacular architectural elements, which can serve as an inspiration for contemporary building design in the context of sustainability. Two main aspects need to be considered: respecting the inter-relationship between humans, nature, climate, and local surroundings, and adaptation of design to the time in which it was created. Svrzo’s house complex, as National Monument, is chosen as a case study, and detailed survey was conducted regarding the presence of sustainable design principles i.e., building form, use of local materials, orientation, adaptation to local climate and topography, passive cooling and natural-induced ventilation, water, and vegetation. A traditional architectural treasure – a functional, simple, and aesthetically valuable concept, shows that ambient requirements were met with minimal energy consumption and material waste from construction to consumption, achieving a responsible ethical attitude towards the environment. The analysis also includes an evaluation of energy efficiency aspects, by comparing the actual heat transmission values of the building elements with the allowable heat transmission values, prescribed by regulation. The actual average heat transmission values are higher which indicates that although the positive impacts of using natural local materials are wide, in terms of enhancing thermal properties, these sustainability features alone are not sufficient to prevent heat losses without proper thermal insulation.

A large number of existing building stock in India was built before the implementation of government guidelines mandating the Green Building Codes. These buildings have been operating with various inefficiencies pertaining to their resource consumption and emissions. Literature suggests that the option of functional retrofitting of building has a potential to reduce this inefficiency by up to 50%. This paper investigates this potential by analysing actual cases of functional retrofitting of buildings (for achieving greater operational efficiency) in Indian context. The environmental impact analysis in this study includes the impact categories of primary energy demand, global warming potential, abiotic depletion potential, ozone depletion potential and water resource consumption for both pre-retrofit and post-retrofit scenario of building. The results are then correlated to the initial cost of functional retrofitting for each case in order to identify the inter-relationship and trend with respect to the level of intervention opted for the cases.

This study aims to reduce the lighting energy consumption in educational buildings while avoiding an increase in cooling load. The Faculty of Engineering building in Universitas Indonesia, Depok, West Java, Indonesia is used as a case study. Daylight optimization can have an impact on lighting energy, which is the largest energy consumer in educational buildings. However, given Indonesia’s tropical climate, daylight leading to heat gain is a concern. Current passive design interventions for controlling daylight and heat gain include light shelves, clerestories, and glazing materials. Daylighting performance is simulated using DIALux software. Results of each intervention are analyzed quantitatively and qualitatively by theories and parameters, namely illuminance level, light uniformity, and overall thermal transfer value (OTTV). Light shelves result in increased uniformity and lower OTTV. Clerestories result in increased average illuminance but higher OTTV. Active intervention with a dimming and grouping system is applied after daylight increases. The combination of passive design interventions and active dimming of electric lights reduces lighting energy with the same OTTV as existing. This study recommends the use of passive and active daylighting strategies considering their effect on the cooling load of buildings.

A sustainable neighbourhood is critical in preserving the environment for future generations, as various societies are suffering from increasing reliance on vehicles and low social interaction. This study aims to compare two neighbourhoods in terms of implementing the sustainable neighbourhood criteria. This study is based on eight sustainable neighbourhood evaluation criteria related to design and urban values are: regional issues, compacted form, mixed land-use, connectivity, pedestrian-oriented building, public sphere of the neighbourhood, relationship with transit, and walkability. University District and Jordan Villa Compound newly developed residential neighbourhoods located in Al-Mafraq city in Jordan were chosen as a case study to evaluate the sustainable neighbourhood criteria. The primary and secondary data were obtained from various resources, including; previous studies that related to the topic, site surveys and personal interviews. The results show that The University District is more sustainable and walkable than the Jordan villa compound; due to several reasons as the grid pattern of planning and the high population density. The importance of this study comes from implementing the sustainable neighbourhood evaluation criteria to develop communities to become more sustainable and walkable.

The benefits of interaction with urban public space, particularly green spaces are numerous for citizens, especially those who live in metropolitan areas. The outbreak of the pandemic, as well as the restrictive measures put in place to prevent the virus's spread, caused enormous changes in people's daily lives and activities. Using a structured questionnaire, the current study intends to capture the shift in attitudes and perceptions of residents of the Attica region during the 2nd wave of restriction measures (7/11/20 – 3/7/21). During the pandemic, visitation in urban public spaces increased, according to the data. The great majority of participants preferred to visit mostly urban public areas within walking distance of their residence (up to 15 minutes), especially in the afternoon and relatively frequently, with 45 percent claiming to visit them "daily" or "3-4 times a week," and only 3% claiming “never”. The analysis showed an increase in the visits during the pandemic from participants who reported better-perceived quality of the spaces, better accessibility, safety during the day, and a feeling of relaxation in the free public spaces of their area. Additionally, those reported living in areas with many available spaces were more likely to increase the frequency of visits during the pandemic.

The materials life cycle consists of several phases. If application areas are targeted for architecture, comprehending the demands of the end-use phase might not be clear at the research and development phase, leading to an entity appearing fragmented. The aim of this study is to help bring order to the material research or development phases. The objective is to generate a review tool, which helps to observe different areas where architecture operates, and contemplate simultaneously the aspects during the different phases of the material development. The review tool of the material life cycle consists of tracking the raw materials until the re-used raw material, resulting in eight different stages of the material life cycle. In addition, each of the eight stages of the material life cycle is possible to observe with the five different viewpoints, which are present in architecture. These eight material life cycle stages and five aspects have been formulated as a chart. The chart consists of 40 different approaches facilitating discussion between different operators during the different phases of the material development. The chart might help set goals, frame areas, and improve comprehension of the research and development processes of the materials, especially when interdisciplinarity is involved in the research process.

Nowadays, ultra-advanced facades have made great strides, and parametric simulation software has made a significant contribution to this advancement. Voronoi shells, based on their irregular nature, are one of the most advanced facades that are being used in modern building facades. In this paper, the main focus is on the behavior of these facades against incident light from the sun. The method presented in this research is based on Ladybug Tool’s plug-in capabilities. Using the analysis of weather information and the desired geometry, direct rays as a vector in each time step is prepared, and the amount of direct sunbeam hours by considering the contexts (Facade) calculated. To estimate the comprehensive method, the same workflow evaluated winter (P2) and summer (P1) solstice as a cross-sectional study (Max & Min solar altitude). The results indicate that the type of geometry Voronoi and the thickness of the facade frame have a great effect on the direction of the rays inwards and also the type of geometry should be controlled at latitudes appropriate to the solar altitude; because of the geometric intricacies of the Voronoi facade have a great deal to do with the solar altitude.

Urban open spaces have frequently been a vital destination for people to connect with one another. The efficiency of urban open spaces depends on their social, health, environmental, and economic benefits. However, little attention has been given to the impact of the relationship between the spatial environment and social interactions on the quality of urban open spaces to be vibrant spaces responding to the change in users’ needs. This study examines the integration between placemaking and space syntax approaches where overlapping relationships between the social and spatial aspects are found. This study aims to extract a conceptual framework with specific stages that can be followed for evaluating “quality” in urban open spaces and then can enhance the weaknesses. Thus, it is to direct the designers’ attention to rediscovering social and recreational uses in these spaces according to people’s needs and spatial configurations. The De Lesseps Bay project in Port Said city, in Egypt, was firstly analyzed through a quantitative method using the space syntax tool “DepthmapX” to understand social decisions and behaviors based on the selected spatial indicators, and secondly through a qualitative method using face-to-face interviews and field observations checklists to understand users’ needs in the place using the Pareto principle and a scoring system. The findings revealed the quality indicators of the place as the most needed factors for users such as attractiveness, vitality, clustered and integrated activities, visual appeal, safety, people connectivity, and accessibility. The spatial relations directly affected the “access and image” and “comfort and image” attributes of the placemaking approach, as well as indirectly affected the “uses and activities” and “sociability” attributes. This paper suggests expanding the concept of “quality” to include the comprehensive principles of creating vibrant spaces to continue responding to the change in community needs and renewal of other things in an urban environment.
{"title":"Toward A Conceptual Framework for Evaluating the Quality of Urban Open Spaces","authors":"Sara Eltarabily","doi":"10.5755/j01.sace.31.2.31311","DOIUrl":"https://doi.org/10.5755/j01.sace.31.2.31311","url":null,"abstract":"Urban open spaces have frequently been a vital destination for people to connect with one another. The efficiency of urban open spaces depends on their social, health, environmental, and economic benefits. However, little attention has been given to the impact of the relationship between the spatial environment and social interactions on the quality of urban open spaces to be vibrant spaces responding to the change in users’ needs. This study examines the integration between placemaking and space syntax approaches where overlapping relationships between the social and spatial aspects are found. This study aims to extract a conceptual framework with specific stages that can be followed for evaluating “quality” in urban open spaces and then can enhance the weaknesses. Thus, it is to direct the designers’ attention to rediscovering social and recreational uses in these spaces according to people’s needs and spatial configurations. The De Lesseps Bay project in Port Said city, in Egypt, was firstly analyzed through a quantitative method using the space syntax tool “DepthmapX” to understand social decisions and behaviors based on the selected spatial indicators, and secondly through a qualitative method using face-to-face interviews and field observations checklists to understand users’ needs in the place using the Pareto principle and a scoring system. The findings revealed the quality indicators of the place as the most needed factors for users such as attractiveness, vitality, clustered and integrated activities, visual appeal, safety, people connectivity, and accessibility. The spatial relations directly affected the “access and image” and “comfort and image” attributes of the placemaking approach, as well as indirectly affected the “uses and activities” and “sociability” attributes. This paper suggests expanding the concept of “quality” to include the comprehensive principles of creating vibrant spaces to continue responding to the change in community needs and renewal of other things in an urban environment.","PeriodicalId":36795,"journal":{"name":"Journal of Sustainable Architecture and Civil Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47601512","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}
