The purpose of this study was to analyze ‘sharing’ as an operational framework for waterfront industrial heritage revitalization in the context of sustainable urban regeneration. This research study was conducted to better understand the public accessibility of heritage preservation projects in a densely populated waterfront urban area and to determine to what extent heritage could be made available to the general public. We examined the development of industrial heritage along Suzhou Creek, Shanghai, and its process of regeneration. The focus area covered a waterway stretch of 19.2 km and an adjacent land area of 11.7 km² managed as a single planning entity on both sides of the creek. We analyzed the present preservation practices and discovered a growing desire to increase the historical buildings’ visibility in the context of urban regeneration. We argue that ‘sharing’ can serve as a pivotal framework for sustainable waterfront regeneration, as its implementation can (1) increase the public value of waterfront heritage and (2) incorporate comprehensive objectives, design strategies, evaluation methods, and public participation into the space revitalization process.

Integrated design of the heating, ventilation and air-conditioning (HVAC) is indispensable to green design because the increasing demand for HVAC systems has led to the diversification of indoor terminals for residential buildings, either focusing on energy efficiency or specializing in creating comfortable indoor environments, and they have different impacts on architectural and engineering design. The paper discussed the assessment-based integration design of the HVAC system, and by introducing case experiences, the whole process of the collaboration between architects and engineers was explored. Various methods were used in the research. The analytic hierarchy process (AHP) was employed to develop the assessment structure and calculate weightings; employing fuzzy comprehensive evaluation (FCE), the social performances of HVAC systems were subjectively evaluated; simulation technology was used to calculate the energy performances; the final results were ranked by the order of preference by similarity to ideal solution (TOPSIS). The research perspective of the collaboration between architects and engineers contributed to the existing literature. Besides, different indoor terminals were analyzed from the two disciplines; an assessment tool (ATI) was conducted and could be referred to; the current green building rating tools were analyzed, and suggestions were proposed to promote the integrated design.

Against the backdrop of rapid global urbanization, peri-urban villages universally face the dual dilemmas of landscape homogenization and the imbalance between heritage preservation and functional renewal. As a typical representative, the “Shanghai-style Jiangnan” villages feature an open water–land chessboard pattern and linear water-house parallel organization, which are distinctly different from the closed and introverted texture of traditional Suzhou-Hangzhou water towns. Such villages urgently need to balance the continuation of the original spatial fabric and the adaptation of modern functions. Existing studies on rural landscapes mostly focus on the static vertical identification of single elements, lacking a systematic quantitative analysis of the horizontal topological relationships among multiple elements, making it difficult to accurately define the spatial boundaries between preservation and renewal. This study takes Xinyuan Village in Jinshan District, Shanghai, as an empirical subject to construct a model for the vertical gene decoding of the “Point-Line-Network” and horizontal topology coupling of “Surface Gene.” By introducing a landscape sensitivity assessment combined with the Entropy Weight Method (EWM) and GIS (Geographic Information System) spatial Kernel Density Estimation (KDE), a quantifiable landscape control heat map is generated. The study identifies the nested original fabric structure of the “house-water-field-forest-road” and the spatial landscape differentiation characteristics in Xinyuan Village and delineates three-tier differentiated zoning controls through dual-verified heat maps. Validated based on Xinyuan Village, this method effectively resolves the conflict between rural preservation and renewal and realizes the transformation from static museum-style preservation to refined adaptive zoning. It provides specific practical strategies for the renewal of “Shanghai-style Jiangnan” villages and offers a quantitative morphological reference for enhancing the spatial resilience and living heritage of peri-urban villages, while its cross-regional transferability needs further verification.

With the rise of the sharing economy and the concept of the sharing city, the field of urban renewal is facing new opportunities and challenges. This paper innovatively explores built heritage renewal in central Shanghai from the perspective of the sharing economy, focusing on the evolution of plot morphology and associated design strategies. Six representative cases, selected within the framework of three urban renewal policies from 1999 to the present, are analyzed using a diachronic method based on the Conzen school and the street frontage index. Combined with historical maps, aerial photographs, and satellite images, the paper analyzes the changes in plot morphology from 1999 to 2024. The paper highlights how the introduction of sharing city principles significantly impacted plot morphology, facilitating the expansion and diversification of space use and driving the restructuring of plot boundaries, including physical, property, and activity boundaries. The study further reveals how the shared city concept has led to the emergence of privately owned public spaces. Additionally, the paper discusses the pursuit of flow, openness, and sharing in urban renewal, noting how these factors have shifted the focus from purely rentable and sellable areas to more efficient space resource allocation, optimizing spatial configurations. Finally, the paper introduces the concept of “sharing by transfer”, proposing that adjustments to plot boundaries under the sharing economy framework can foster more equitable, efficient, and sustainable urban renewal, providing new perspectives and strategic recommendations for built heritage renewal.

Amid rapid urbanization in China, widespread gated residential districts have created physical and visual isolation from surrounding nature, undermining environmental benefits and daily accessibility. The emergence of a twenty-first-century “sharing” paradigm reshapes how buildings and landscapes are used and experienced, opening new opportunities for diversified sharing between communities and natural systems. Yet, despite mature research on city-scale landscape sharing, micro-scale tools to balance sharing versus exclusive route allocation—and to operationalize cross-system sharing-route design—remain limited. This study examines nature-integrated community design through the Landscape Route Sharing Ratio (LRSR), a metric derived from the Length and Density of Sharing Landscape Route (L_s/D_s), the Length and Density of Non-shared Landscape Route (L_ns/D_ns). It analyzes eight cases using a mixed-methods approach (field surveys, spatial mapping, planning-document review and quantitative measurement), and identifies five core cross-system features through typological analysis: extension to surrounding landscapes (ENL), cross-boundary landscape axes (CBLA), multi-scale hierarchy (MSH), multi-elevation systems (MES), and non-motorized priority (NMP). This study demonstrates that higher LRSR values significantly enhance landscape integration and pedestrian experiences. By establishing actionable target ranges (0.50–0.70), the research provides a practical decision-support tool for nature-integrated community design, advancing the methodological understanding of how shared routes foster ecological and social vitality in contemporary urban environments. The framework effectively bridges the gap between quantification with design guidance for nature-integrated communities.
