“…In fact, Using PV is the most effective technique in contrast with aforementioned building techniques regardless of its affordability and usability. The net zero energy design could be achieved by the installation of rooftop PV of the capacity 12.5 kW and 30 kW for villa and apartment, respectively [68]. A similar pattern of results was observed in the study by Wang et.…”

Energy consumption in the building sector accounts for a large percentage of global energy consumption. For this reason, it is essential to take action to minimize this destructive consumption and promote energy conservation practices within the building sector. A Zero Energy Building (ZEB) concept has been proven as a viable technique for improving energy efficiency in various climatic conditions. This concept can minimize the environmental impact of buildings and helping to advance sustainable development in the construction industry. Worldwide, the ZEB is of the utmost importance to meet sustainability development goals in the built environment. The building sector in the Kingdom of Saudi Arabia (KSA) consumes about 75% of total electrical energy. KSA has experienced an unprecedented energy consumption in the last decade. This is due to the country's rapid population growth and urbanization, which in turn put more pressures on the kingdom's natural resources. However, KSA is committed to promote energy efficiency and renewable energy technologies to achieve the goals of sustainability development, as part of its Vision 2030. This paper therefore explores various green building solutions, especially in hot-arid regions, with the aim of reaching ZEB, and at the same time minimizing potential adverse environmental impacts. In order to verify proposed solutions, energy simulation software (Integrated Environmental Solution-IES) is used, along with reviews of related work. The major finding of this paper reveals that several green building concepts are crucial to the design and operation of a building in hot dry region, including thermal mass; daylight; natural ventilation; cavity wall; double-glazing and solar panels (PV). Bear in mind that the operation of a building has to be powered by a Building Management System (BMS). This paper also proposes an auxiliary holistic framework that explains how green practices such as Zero Energy Buildings (ZEBs) can be achievable in Saudi Arabia with no harm to its local environment.INDEX TERMS zero energy building; sustainable development; climatic conditions; simulation

“…Bekun et al (2021) believes that sustainable economic growth can be achieved by developing clean technologies and increasing the share of renewable energy in the energy structure. Krarti and Aldubyan (2021) advocated the use of photovoltaics and wind as renewable energy technologies to achieve carbon neutrality in residential communities. Cao et al (2021) studied the impact of cleaner production standards on the total factor productivity and resource allocation efficiency of Chinese energy companies.…”

Knowledge sharing (KS) in the green supply chain (GSC) is jointly determined by the KS efforts of suppliers and manufacturers. This study uses the differential game method to explore the dynamic strategy of KS and the benefits of emission reduction in the process of low carbon (LC) technology in the GSC. The optimal trajectory of the knowledge stock and emission reduction benefits of suppliers and manufacturers under different strategies are obtained. The validity of the model and the results are verified by numerical simulation analysis, and the sensitivity analysis of the main parameters in the case of collaborative sharing is carried out. The results show that in the case of centralized decision-making, the KS efforts of suppliers and manufacturers are the highest, and the knowledge stock and emission reduction benefits of GSC are also the best. The cost-sharing mechanism can realize the Pareto improvement of GSC’s knowledge stock and emission reduction benefits, but the cost-sharing mechanism can only increase the supplier’s KS effort level. In addition, this study found that the price of carbon trading and the rate of knowledge decay have a significant impact on KS. The study provides a theoretical basis for promoting KS in the GSC and LC technology innovation.

“…A growing number of cities have recognized their potential contribution to mitigate climate change and aspired to achieve net-zero [8]. Clean energy and energy efficiency are probably the mainstream topics to achieve carbonneutral cities [9]. Cities cannot achieve net-zero by reducing emissions without improving vegetation carbon sequestration from urban and regional landscapes [8].…”

Rapid urbanization has threatened sustainable urban development in many cities across the globe, causing green space loss and vegetation cover degradation which reduce carbon sequestration. Optimal land management practices (LMPs) in an urban context are known as ways capable of promoting urban vegetation growth and contributing to carbon sequestration. Due to variations of physical, biological, and social structures in urban areas, policymakers often lack relevant information to decide and implement site-specific LMPs. Here we try to extract the areas in need of the optimal LMPs, identify location-dependent optimal LMPs, and assess how much more carbon can be captured by applying a combination of segmenting homogeneous urban environments and neighborhood-based analysis. As one of the most developed cities in China, the greater Guangzhou area (GGA) was selected as a case study. We found that the carbon uptake from the urban vegetation in GGA could be improved on average by 185 gC m−2 yr−1 in flux (or 1.3 TgC yr−1 in total) with optimal LMPs, equivalent to a ~30% increase considering the current level of 662 gC m−2 yr−1 in flux (4.4 TgC yr−1 in total). The carbon uptake potential was found to differ considerably across locations and among different ecosystem types, highlighting spatially varied priorities for implementing optimal LMPs over the space. This study reveals the usefulness of the model in assessing carbon uptake potential from optimal LMPs and emphasizes that future urban planning may consider the importance of optimal LMPs in enhancing vegetation carbon uptake in urban planning.
