As the most historically and culturally valuable city district in Nanning, Xingning Block has gradually formed its own unique color characteristics and architectural style in the slow process of urban historical development, showing the unique local customs and architectural features. However, restricted by the specific development conditions, many undesirable aspects can be found in the overall architectural landscape color of some nodes on the block, such as lack of systematic planning, poor material matching, messy building color, as well as various challenges of contemporary social development to the architectural environmental color on the block.The architectural environmental color of urban traditional blocks is an important part of the specific history, culture and spirit of the times of a city, which plays a vital role in the development and change of the city. Therefore, how to effectively and reasonably do a good job in sustainable urban planning and development is an issue that must attract the attention of competent authorities at all levels, scientific research institutions and planning practitioners.

Cities have been the focus of recent sustainability and climate change mitigation efforts primarily because of unprecedented urban growth and ever-increasing resources consumption. A worrying trend has been the ever-decreasing life of buildings in cities because of premature building obsolescence. Premature building obsolescence has been cited as the major driver of demolition waste which accounts for more than 40% of total waste generated annually. This waste stream poses a bigger challenge as the pressure on natural resources increases with urban growth. A traditional way of looking at the urban sustainability has been from the perspective of the environmental sciences and waste management methods. Analyzing urban areas with design science perspectives could provide novel insights to improve existing resource consumption patterns and transform sustainability growth in cities. This study focuses on the problem of demolition waste arising from the premature building obsolescence in cities. It applies a design research methodology framework for identifying existing problems associated with demolition waste and generating strategies to transform cities into more sustainable urban systems. In the problem clarification phase, a detailed literature review was supported with stakeholder’s interviews to identify the state-of-art for building demolition process and demolition waste. Research was further extended to descriptive study-I phase to carry out a demolition case study and generate support tools to enable transformation in the existing scenario for achieving a desired state. Singapore, a dense city state of South-East Asia has been taken as a case study in this research. Results show that applying design research methods could help open-up a new dimension to solve urban sustainability challenge for built environment. It highlights that material reuse could lead to significant improvement in the built environment sustainability but the challenge associated with realization of material reuse practice needs to be addressed. Descriptive study-I concludes with the strategies on creating a reuse market through entrepreneurial innovation and an alternative material supply chain of secondary materials for regional housing demand. These results highlight the role of design research methods for tackling complex systems level problems in cities.

Tujuan penelitian ini adalah mengungkap keberadaan Rapa’i Daboih sebagai  reproduksi budaya yang terjadi di perkampungan CARE bekas pengungsian korban pascatsunami di Aceh 2004 lalu. Identifikasi reproduksi budaya ditinjau dari pemkanaan ulang seni pertunjukan Rapa’i Dabo’ih oleh Grup Bungong Sitangkee di Kecamatan Kota Jantho Kabupaten Aceh Besar. Metode yang digunakan adalah metode kualitatif, pengumpulan data dilakukan melalui observasi dan mengamati pertunjukan dan wawancara. Hasil penelitian ini mengungkapkan bagaimana kebradaan reproduksi budaya dengan studi kasus Rapa’i Dabo’ih.Kata Kunci: rapa’i dabo’ih, reproduksi, budaya.AbstractThe Bungong Sitangkee group's creativity demonstrates Rapa 'i Daboi'h is an effort to reproduce culture in the CARE (Non Government Organization) in Teurebeuh village, JAntho City District, Aceh Besar District. Rapa’i Dabo’ih is an amazing performing arts performance. This performance art is favored because of the attractive form of the Rapa'i Dabo'ih show with debus as the culmination of the game accompanied by the Rapa'i instrument with the recitation of verses containing Islamic symbols. Cultural reproduction is the process of maintaining cultural identity carried out by post-tsunami victims who have settled in ex-refugee areas as a preservation and existence of their original culture. The purpose of this study is to uncover the existence of Rapa'i Daboih as a cultural reproduction that occurred in the CARE village of ex-refugee victims after the tsunami in Aceh in 2004. Identification of cultural reproduction is reviewed from the reopening of the Rapa 'i Dabo'ih performance by the Bungong Sitangkee Group in Kota Jantho District, Aceh Besar Regency. The method used is a qualitative method, data collection is done through observation and observing performances and interviews. The results of this study reveal how the existence of cultural reproduction with the Rapa'i Dabo'ih case study.  Keywords: rapa'i dabo’ih, reproduction, culture.

The Impact

This paper explores the impact of water conservation and rainwater harvesting practices implemented at the site or district scale on the infrastructure, energy and water cycles of their larger urban systems. A case study is presented of a conceptual development in a Southeast Asian climate. Two technologies are examined: water-efficient fixtures and appliances and rainwater harvesting and beneficial use. Practices to reduce water consumption at the site or district scale have implications in the larger system, ranging from reductions in water that has to be treated and distributed, reductions in wastewater that has to be collected and treated, and reductions in energy consumed. Similarly, using rainwater for irrigation will reduce the amount of potable water demand, and will have system energy implications. The paper considers performance criteria for the entire water-energy system, including peak runoff, pollutant loads, energy and carbon footprints.

The residential sector accounts for a large share of worldwide energy consumption, yet is difficult to characterise, since consumption profiles depend on several factors from geographical location to individual building occupant behaviour. Given this difficulty, the fact that energy used in this sector is primarily derived from fossil fuels and the latest energy policies around the world (e.g., Europe 20-20-20), a method able to systematically integrate multi-energy networks and low carbon resources in urban systems is clearly required. This work proposes such a method, which uses process integration techniques and mixed integer linear programming to optimise energy systems at both the individual building and district levels. Parametric optimisation is applied as a systematic way to generate interesting solutions for all budgets (i.e., investment cost limits) and two approaches to temporal data treatment are evaluated: monthly average and hourly typical day resolution. The city center of Geneva is used as a first case study to compare the time resolutions and results highlight that implicit peak shaving occurs when data are reduced to monthly averages. Consequently, solutions reveal lower operating costs and higher self-sufficiency scenarios compared to using a finer resolution but with similar relative cost contributions. Therefore, monthly resolution is used for the second case study, the whole canton of Geneva, in the interest of reducing the data processing and computation time as a primary objective of the study is to discover the main cost contributors. The canton is used as a case study to analyse the penetration of low temperature, CO2-based, advanced fourth generation district energy networks with population density. The results reveal that only areas with a piping cost lower than 21.5 k/100 m2ERA connect to the low-temperature network in the intermediate scenarios, while all areas must connect to achieve the minimum operating cost result. Parallel coordinates are employed to better visualise the key performance indicators at canton and commune level together with the breakdown of energy (electricity and natural gas) imports/exports and investment cost to highlight the main contributors.

Currently, remarkable gaps of operational, social and environmental efficiency and overall sub-optimization of the logistics and mobility systems exist in urban areas. There is then the need to promote and assess innovative transport solutions and policy-making within SUMPs (Sustainable Urban Mobility Plans) to deal with such critical issues in order to improve urban sustainability. The paper focuses on the case study of the Venice Lagoon, where islands—despite representing a relevant feature of urban planning—face a tremendous lack of accessibility, depopulation, social cohesion and they turn out to be poorly connected. By developing an original scenario-building methodological framework and performing data collection activities, the purpose of the paper consists of assessing the feasibility of a mixed passenger and freight transport system —sometimes called cargo hitching. Mixed passenger and freight systems/cargo hitching are considered as an innovative framework based on the integration of freight and passenger urban systems and resources to optimize the existing transport capacity, and thus, urban sustainability. Results show that the overall existing urban transport capacity can accommodate urban freight flows on main connections in the Lagoon. The reduction in spare public transport capacity, as well as in the number (and type) of circulating freight boats show—in various scenarios—the degree of optimization of the resulting urban network configuration and the positive impacts on urban sustainability. This paves the way for the regulatory framework to adopt proposed solutions.
