Considering this, it is very important to study the causes of city problems and to develop city models implementing sustainability practices. There are a limited number of studies developing sustainable city models, but in the scientific community there is an even greater lack of studies about the rehabilitation of current cities to implement these models. This work emerges with the objective of analysing how it is possible to implement sustainability practices in cities through the development of a sustainable city model and an urban rehabilitation plan. The development of sustainable city models is a very complex topic and the analysis of the literature shows that it is necessary to consider the relation between environmental and social aspects in the development of sustainable cities, while taking special care when considering the economic ...","PeriodicalId":38108,"journal":{"name":"International Journal of Sustainable Building Technology and Urban Development","volume":"5 1","pages":"297-305"},"PeriodicalIF":0.0,"publicationDate":"2014-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/2093761X.2014.948528","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"60074861","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}

Most of the existing methodologies do not take into account the influence of the windows on the cooling needs, but indicate only their performance during the heating season. However, at the present time the cooling performance is becoming a significant parameter for evaluating the overall building energy performance in Europe.Within this context the current paper attempts to propose a new system for assessing the cooling performance of the windows at a pan-European level. The paper starts with a brief presentation of the existing window energy rating systems found worldwide.

If the present trends continue, Chinese suburban density will be around 2500 inhabitant/km2 in 2030, with suburbs 36 times bigger in surface than the core, as the Shanghai case exemplifies. It would notably lead to a tripling of energy demand for transportation and contribute to increasing the infrastructure costs per capita. China needs an urgent and ambitious shift toward infill urban development to avoid the current trend of edge and leapfrog growth that feeds de-densification and urban sprawl. National and local policies must promote and foster compact urban development and high levels of articulated density: high residential density, high job density, neighbourhood scale mixed use, and high density of urban amenities to improve accessibility.","PeriodicalId":38108,"journal":{"name":"International Journal of Sustainable Building Technology and Urban Development","volume":"13 1","pages":"100-108"},"PeriodicalIF":0.0,"publicationDate":"2014-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/2093761X.2014.908813","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"60074594","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}

Compared to usual buildings on land, floating buildings on water have great advantages in terms of sustainability. Sustainability in architecture has primarily dealt with physical aspects, but discussions of sustainability need to be extended to non-physical aspects because buildings are to be used by people with various purposes and meanings. Sustainability of floating architecture in three dimensions can be summarised as durability to a rise in water level, long term usage due to movability and relocation, use of local material, and various applications of renewable energy sources in the environmental dimension; economic advantages due to prefabrication and modular construction, and economic efficiency due to high utilisation rate through global mobility in the economic dimension; and residents' psychological comfort, strengthened security against crime, and high sense of community in the social dimension.","PeriodicalId":38108,"journal":{"name":"International Journal of Sustainable Building Technology and Urban Development","volume":"5 1","pages":"123-127"},"PeriodicalIF":0.0,"publicationDate":"2014-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/2093761X.2014.908809","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"60074580","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}

The purpose of this research is to assess the feasibility of a utility-scale photovoltaic (PV) electricity generation system on Illinois State University's (ISU) campus. The potential power production from the PV system can be estimated through analysis of the climate information and utilising PV system modeling software. In this feasibility analysis, eight utility-scale PV systems were modeled and simulated to determine three optimal systems for the university.

It analyses Frank Lloyd Wright's design of the Florida Southern College campus in Lakeland, Florida in the United States as a case study. This campus contains the largest unified collection of Wright's architecture. Between the 1930s and the 1950s, he designed the master plan as well as 10 individual buildings for this project. These buildings compose the core of the campus, which is located on a hillside facing a lake to the south. The campus serves as a critical exemplar for demonstrating the cohesive interaction between humanity, buildings, and landscapes that is lacking in typical modernism. In addition, this campus demonstrates influences from various Eastern thoughts on Frank Lloyd Wright's design. The preservation of this campus is not only related to the cultural and historical identity of this college, but also acts as a lived site for visitors to reflect on the fundamental meaning of human existence. ...","PeriodicalId":38108,"journal":{"name":"International Journal of Sustainable Building Technology and Urban Development","volume":"5 1","pages":"135-142"},"PeriodicalIF":0.0,"publicationDate":"2014-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/2093761X.2014.914984","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"60074647","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}

The building simulation program EnergyPlus was used to model a full variable speed chiller system and a conventional system operating for a reference office building. Simulation results show that the environmental performance of the sustainable system is superior to the conventional ones with annual electricity saving of 25.7–31.5%, water saving of 1.8–2.2% and carbon emissions reduction of 25.6–30.3% under the three climate change scenarios.
