Issues and challenges of implementing comprehensive renovation at aged communities: A case study of residents’ survey

A Digital Twin Approach to City Block Renovation Using RES Technologies

“…Social factors such as a lack of understanding of renovation benefits, insufficient communication between stakeholders, and "Not-In-My-Backyard Syndrome" can cause negative perceptions about renovations and slow down the pace of their implementation. The willingness of tenants to participate in renovations is a crucial factor affecting the pace of renovations [17]. The lack of capital, reliable information, and uncertainties regarding the potential benefits frequently lead to the neglect of investments in energy efficiency measures [18].…”

“…Additionally, the tenants often prioritized immediate financial concerns over energy efficiency improvements. Research by Yang et al [17] showed that residents demonstrated a positive inclination towards accepting fundamental renovation measures. However, they expressed a relative unwillingness to embrace measures focused on enhancing quality and integrating renewable energy sources.…”

Risk allocation of old community renewal PPP project in China--An improved TOPSIS approach

“…During the past 40 years, the Chinese government has implemented series of related policies to promoting urban renewal, and the intension of urban renewal has changing from the large-scale reconstruction to the gradual organic renewal based on city planning (Pan and Du, 2021;Hui et al 2021;Zhu et al 2020). As an essential part of urban renewal, the renewal of old community is a direct embodiment of gradual organic renewal , which is effective in improving the function of the stock buildings and satisfying the living request (Liu et al, 2021;Li et al, 2022). In China, the old community refers to those residential districts with age-old buildings, low construction standards, incomplete use functions, incomplete supporting facilities, and lack of management and maintenance that cannot meet people's normal living needs (Huo et al, 2022;Zhu et al, 2020).…”

“…In China, the old community refers to those residential districts with age-old buildings, low construction standards, incomplete use functions, incomplete supporting facilities, and lack of management and maintenance that cannot meet people's normal living needs (Huo et al, 2022;Zhu et al, 2020). A few of research has pointed out the multiple benefits of old community renewal, including increasing the service life and value of the original buildings (Menassa, 2011;Jagarajan et al, 2017;Wang and Yang, 2022), enhancing the living standard of residents (Yang et al, 2019;Liu et al, 2021), improving the urban environment (Tan et al 2018;Baldwin et al, 2018), as well as bringing new investment demands (Wang et al, 2015). Li et al (2021) categorized these benefits into economic, environmental, and social aspects, and the fuzzy mathematical models were applied to evaluate the comprehensive benefits of the renovation of old community quantitatively, in which the environmental benefits were found to be the most important factor, and the impact of living comfort on the overall benefits was the most significant.…”
