The combination of urbanization and global warming leads to urban overheating compounds the frequency intensity extreme heat events due climate change. Yet, risk can be mitigated by green-blue-grey infrastructure (GBGI), such as parks, wetlands, engineered greening, which have potential effectively reduce summer air temperatures. Despite many reviews, evidence bases on quantified GBGI cooling benefits remains partial practical recommendations for implementation are unclear. This systematic...

The currently consumption-driven society produces an enormous volume of waste every day. Continuous depletion natural finite resources by urban populations is leading the globe to uncertain future. Therefore, prevent further global resources, sustainable consumption and a strategic management system would be required. It evident that significant number non-renewable such as cadmium, mercury tellurium will experience permanent shortfall in supply within next two three decades. Astonishingly,...

Beyond energy efficiency, there are now urgent challenges around the supply of resources, materials, energy, food and water. After debating efficiency for last decade, focus has shifted to include further resources material efficiency. In this context, urban farming emerged as a valid design strategy, where is produced consumed locally within city boundaries, turning disused sites underutilized public space into productive landscapes community gardens. Furthermore, such agricultural...

New urban design concepts should guide the inclusion and re-introduction of greenery biodiversity in built environment. Preserving face urbanization, habitat fragmentation, environmental degradation climate change is probably one greatest challenges our time. The integration trees, shrubs flora into green spaces gardens city particularly important helping to keep environment cool, because buildings pavements increase heat absorption reflection (what called island effect). Tomorrow's...

Purpose – This paper aims to present a survey of the perceptions barriers implementing reverse logistics (RL) practices in South Australian (SA) construction organisations. Despite extensive research on forward and RL, there is paucity studies that examine RL particularly within industry. study builds ongoing being undertaken by authors, entitled “Designing for (DfRL) building life cycle: practices, drivers barriers”, which examining best could be used as “road map” developing appropriate...

Resource challenges are particularly dominant in fast-expanding cities the Southeast-Asian region and include inefficient infrastructure systems leading to energy black-outs, urban flooding, lack of waste recycling increasing emissions air pollution. This article addresses development integrated planning approaches as a tool for increased resource efficiency. It aims link circular economy discourse with Urban Nexus. Three specific case studies called ‘living labs’ implemented Nexus approach...

The question of density is closely connected to urbanization and how our cities may evolve in the future. <em>Density</em> <em>compactness</em> are two related but different criteria, both relevant for sustainable urban development transformation cities; however, their relationship not always well understood. While a high degree compactness desirable, too much can be detrimental liveability, health well-being. purpose this article report first on an extreme case hyper-density: Kowloon Walled...

The Urban Heat Island (UHI) effect can result in higher urban densities being significantly hotter (frequently more than 4 °C, even up to 10 °C) compared their peri-urban surroundings. Such artificial heat stress increases the health risk of spending time outdoors and boosts need for energy consumption, particularly cooling during summer. structure, land cover metabolism are underlined as key contributors city scale. Under question is which configurations make precincts microclimates...

The properties of human skin strongly depend on hydration. Skin friction, elasticity and roughness change significantly in the presence water. This paper presents a new bio-mimicking gelatine-based physical model that simulates frictional behaviour against widely-used standard textile under dry wet conditions over broad range applied normal load (0.5–5 N) amount water at interface (0–100 μl/cm2). proposed shows good agreement with both conditions. In addition, tensile Young's modulus surface...
