Public spaces contain variations within each other from the physical appearance, activities, and to usage factors. Private sector involvement for public space provision was increased in the recent past where public space ownership and access controls were shifted from solely public to private. This was criticized as privatization of public space and lead to debates on the decline of publicness and privacy of space. In this context, this research studied the public space from the user perception by considering publicly owned and operated versus privately owned and operated public spaces within Colombo, Sri Lanka. It is also explored the balance between ownership and access controls to determine the user preference in terms of the publicness features. User defined public space features were identified using 35 semi-structured interviews and 119 online questionnaire surveys. Qualitative analytic tools were used to evaluate the results including Content analysis and Space-shaper models with the support of NVivo software. The results revealed that publicly owned spaces were preferred by the users due to easy access and freedom for activities while privately owned spaces were preferred due to better infrastructure, safety, and security within. Also, it is identified that urban public space offered users the freedom to experience based on the levels of ownership and access controls. Finally, people preferred ownership by public over private sector as anecdotal evidence and values dominated in the public space attributes. This study provides key insights for planners to consider in the public space planning and the importance of private sector involvement and balance in the provision of optimal urban spaces in cities.","PeriodicalId":106153,"journal":{"name":"14th International Research Conference - FARU 2021","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127401494","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 view of this, an attempt was made to determine the impact of interior colours to reduce depression, anxiety and stress levels of disabled individuals. The investigation was executed with reference to wall colour of patient’s (n=15) bedrooms of a selected rehabilitation centre, at Ragama. The impact of three selected hues (blue, yellow and green) were tested by installing colour panels on the sidewall of the beds, allowing the participants to be exposed to each colour for three consecutive days. Depression, anxiety and stress levels of participants were measured using DASS-21. Impact of green colour was found to be more favourable to reduce depression, anxiety and stress levels of participants over blue and yellow. It is recommended to extend this study further to test different hues, shades and intensities of green colour with long-term exposure, to enhance psychological health and well-being of disabled patients in health care facilities.","PeriodicalId":106153,"journal":{"name":"14th International Research Conference - FARU 2021","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131112740","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 such a setting, understanding the responsiveness of the built environment for active aging is crucial. However, even the few available studies are prioritized on health rather than the built environment attributes. Therefore, this study aims to assess the built environment attributes related to elders, for the first time, in developing countries like Sri Lanka. The assessment method composes of two case studies in Colombo, Sri Lanka with a questionnaire survey, an axial map, and a frequency analysis using the SPSS software. The case studies comprise of a middle-income and a low-income settlement both with high population density. The analysis results explicitly informed that, in comparison, the middle-income settlement is more adversely affected by the built environment response related to health and social relationships. This finding is further supported by the prominence in health-related issues of loneliness (ρ-value .042) and lack of freedom (ρ-value .014) in the middle-income settlement. The built environment attributes were ranked based on their significance in correlation with the Quality-of-Life measures and the individual age-related characteristics. This was further developed for an appraisal that assesses health-related aspects of built environment response for vulnerable age groups like elders. The findings and the appraisal could support the future decision-making process of the National health budget and future urban design interventions since Sri Lanka has the highest South Asian aging population.","PeriodicalId":106153,"journal":{"name":"14th International Research Conference - FARU 2021","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132672396","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 Asian countries, streets have evolved from traditional streets without interpreting the actual need and impact of street elements for walking behaviour. However, they act only as transportation links while limited to the name by itself. This research aimed to identify the street elements that influence walkability and to investigate the most influential factor for walkability in terms of “Link and Place” to promote walkability in the Sri Lankan context. This study was conducted using a mixed-method approach. The on-site observations were carried out through a photograph survey and rough sketches to observe the street elements. Later, findings were validated through the questionnaire survey regarding the seven principles of a walkable street. Then, data were analysed by using descriptive analysis and correlation analysis aided by SPSS software. The findings of the observation and questionnaire revealed that there are nine most common street elements of streets which influence walkability in the Sri Lankan context. Finally, the study agreed that both “Link and Place” functions are equally important for the walkability of pedestrians.","PeriodicalId":106153,"journal":{"name":"14th International Research Conference - FARU 2021","volume":"143 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116208850","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}

Nevertheless, the construction industry has created severe adverse environmental impacts. Therefore, green building technologies are implemented to alleviate the adverse effects of the construction industry. Using green materials instead of conventional building materials with high environmental impacts has been identified as one such implementation. However, there seems to be much confusion in defining green building materials. Hence, it is vital to explore the features of green building materials. Therefore, this article investigates green features that qualify the building materials as green building materials. A qualitative research approach was selected as the research methodology, and semi-structured interviews were conducted with seven green building experts. The data was analysed using content analysis. Findings revealed that recycled content, local availability of materials, embodied energy of materials, use of rapidly renewable material, usage of waste material for the production process, material wastage content in the production process and pollution prevention in the production process are the green features. The study results guide the identification of green building materials that can replace the materials with poor environmental sustainability.","PeriodicalId":106153,"journal":{"name":"14th International Research Conference - FARU 2021","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124059734","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}

When considering the carbon emission in the local context, even though there are Input-Output Tables (IOTs) that applies to all types of industries in Sri Lanka, there seems to be limited focuses on IOTs specifically relating to the construction activities which is vital for the need due to its outstanding contribution to the carbon footprint of Sri Lanka. Hence, this study aims to calculate the carbon footprint construction activities in Sri Lanka using IOT with a bottom-up approach. The required data were extracted from published documents of Survey of Construction Industry by Census and Statistics, and The Inventory of Carbon and Energy (ICE) database of UK. Carbon footprint of construction activities were calculated using IOT with a bottom-up approach. The analysis revealed that the road and railway sector have the highest contribution of 48% to the monetary value of the construction industry meanwhile it accounts for 44% of the highest carbon emission to the atmosphere in the year 2020. Subsequently, activities related to non-residential residential, and utilities contribute to 20%, 15%, and 12% of total carbon emission respectively. In terms of construction materials, cement-based activities (59%) were the highest contributor while rubble and metal-based (23%), and iron and steel-based activities (17%) were next level contributors to the carbon emission due to construction. The analysis concluded that the as the initiatives, public sector projects including road and railway sector and utilities should integrate more sustainable construction practices as they are responsible for more than 50% of carbon emission.","PeriodicalId":106153,"journal":{"name":"14th International Research Conference - FARU 2021","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124898022","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}
