“…However, the provincial governments have developed performance evaluation for energy savings, carbon intensity, renewable energy concentration, and forest coverage, which binds local officials' professional promotion to reduction targets [165]. The lack of comprehensive national, provincial, and city evaluation protocols has led to many studies that have developed and evaluated the progress of LCC nationally [169,170], provincially [171,172], and city-wide [10,118,148,173]. These studies indicate that there is a need for a scientifically rigorous MER system, which is locally specific, incorporates multiple stakeholders in the planning process, and covers not only technology, economic, and environmental parameters, but also social equity.…”

“…Between 1978 and 2010, the total number of cities snowballed from 198 to 657, with eight megacities having more than 10 million people and 103 cities having over one million people [7]. At the end of 2014, the urbanization rate of China had increased to 54.77%, with continued projected growth to 65% by 2030 and 75% by 2050 [8][9][10]. These driving forces have caused a massive upsurge in demand for energy [11], as today, urban areas represent 84% of the primary energy consumption in the country [12].…”

Low carbon city (LCC) has emerged as the latest sustainable urbanism strategy in China as a response to climate change impacts. Yet, minimal scholarships have explored the sustainability of the urban planning model towards understanding the complexity of the components. Using a two-step triangulation approach, this paper presents a structured overview of the LCC initiative in China as it relates to the transition to a sustainability paradigm. The data collection approach includes a comprehensive review of 238 articles on LCC to identify and categorize LCC components. Furthermore, discourse and framing analysis was used to develop and synthesize a conceptual framework for assimilating the components into four core sustainable development principles: Integration, implementation, equity, and scalability and replicability. The results indicate that LCC development in China is bias towards economic and environmental technological innovations and strategies. Additionally, several critical sustainability issues of LCC pilots were identified. These include a lack of social equity planning concerns for the most vulnerable population, dearth of social reforms that cater to lifestyle and behavioral change, top-down planning and decision-making processes, a technocratic rationalization planning approach, inconsistent LCC targets on inter-generational justice concerns, absence of an effective national "sharing and learning" city-city network system, and several barriers to implementation. We conclude that the applied theoretical and conceptual inquiry into the field of LCC is pertinent to mitigate climate change and achieve sustainable urban development.Sustainability 2019, 11, 4342 2 of 37 consumption [14][15][16][17]. This increasing energy consumption and coal dependency of the urban energy system has increased greenhouse gas (GHG) emissions, as China has become the world's largest energy consumer and carbon emitter [18,19]. A recent report by the National Bureau of Statistics [20] suggests that despite a decline in GHG emissions between 2013 and 2016, emissions grew by 2.3% in 2018 due to a surge in urban construction. Therefore, after three decades of rapid physical and socio-spatial modernization, the country is facing significant negative externalities [16]. Local environmental pollution [6,16,[21][22][23], ecological deterioration [24], and energy shortage [21,25] have created health risks [26], have affected people's quality of life [27], and resulted in substantial economic losses [28] in megacities such as Tianjin and Beijing [29]. Concomitantly, China's cities are vulnerable to climate change impacts [17,30], as some cities have inadequate seawall defenses in low-lying areas [5], and are therefore exposed to flooding and extreme rainstorms [23]. In addition to this, some experience droughts from reduced precipitation, which can be attributed to low urban institutional capacity that creates limitations in climate governance and planning [31]. These complex and intractable problems have heralded a call for action, t...

In cold environment, the damage of freezing and thawing poses a great threat to the safety of concrete structures. In this study, six frost-damaged squat reinforced concrete (RC) shear walls were subjected to low cyclic reversal loading to investigate the effects of axial compression ratio, concrete strength and freeze-thaw cycles (FTCs) on the seismic performance of squat RC shear walls. The seismic behavior of the test specimens was evaluated in terms of the frost action at the microstructure level, frost-heave crack patterns, damage processes, failure patterns, hysteretic behaviors, skeleton curves, deformations, and energy dissipation capacities. It shows that the boundary elements and distributed reinforcements had obvious restraining effects on the development of frost-heave cracks. The FTC action weakened the load-carrying capacity, energy dissipation capacity, and shear resistance capacity of the walls. When the number of FTCs is kept at 200, with the increase of the concrete strength, the gel structure (C-S-H) gradually evolved from fibrous to nets, also the width and number of frost-heave cracks started to reduce, and the distribution of frost-heave cracks evolved from the middle of the specimen to the perimeter. Moreover, the energy dissipation capacity and the ratio of the shear displacement on the whole displacement after cracking loading condition started to increase.

“…This method has been used by many scholars to study SUHI effect. Researchers tested in different LCZ areas found that SUHI intensity was positively correlated with building surface fraction (BSF) and negatively correlated with ratio of green space (GSP) and water area fraction (WAF) [5][6][7]. AT data often have the defects of few stations and difficult to conduct research in large range.…”

Urbanization seriously affects the urban climate and the quality of human settlement. Based on Landsat8 remote sensing and building vector data, local climate zone (LCZ) method is employed to study the influences of urban form on land surface temperature (LST) of Xi'an. The results confirmed that the LST of the built-up LCZ is higher than the land cover LCZ. In built-up LCZ, LST is increasing with the increasing of building density. In land cover LCZ, the LST of bare land is the highest. Surface urban heat island (SUHI) of 14 samples in LCZ also been calculated. Highest SUHI intensity is found in low-rise buildings with high density area. LST intensity of water body and forest are lower than others in land cover LCZ.
