The street lighting integrated system case study, control scenarios, energy efficiency

Purpose – The purpose of this paper is to suggest the usage of the project finance (PF) scheme as a suitable mechanism to fund energy efficiency projects at the urban scale and present its advantages and adoption barriers. Design/methodology/approach – A case study is developed to renew the traffic lighting system of an Italian town via replacement of the old lamps with new light-emitting diode (LED) technology. Several partners are involved in the case project to construct a viable PF arrangement. Findings – The case study presents the viability of the proposed PF scheme that provides for acceptable financial returns and bankability. However, it also shows that the need for short concession periods may call for a public contribution to the initial funding to make the project more attractive to private investors. Practical implications – This case study is a useful guideline for governments and promoters to using the PF arrangement to fund energy efficiency investments in urban settings. It helps designing an appropriate PF scheme and understanding the advantages of PF to reduce risk and, consequently, increase the debt leverage and profitability of energy efficiency projects. Originality/value – This paper contributes to bridging the gap about the lack of works addressing the implementation of the PF mechanism in the energy efficiency sector in urban areas. The importance of this paper is also associated with the shortage of traditional public finance faced by many cities that forces to seek for alternate forms of financing.

Depth Interviews

This study investigated the resilience of the Chinese child protection system in responding to the special needs of children in difficulty under the specific circumstances caused by the COVID-19 pandemic. This study applied qualitative document analysis of child protection administrative documents, in-depth interviews with 13 child protection professionals, and an in-depth case study of 14 children living in difficulty, complemented by relevant information available in the media. The results indicate that there are good policies in China’s child protection services but the organizational and functional fragmentation complicates implementation, suggesting a need for the development of bottom-up practices. The essential conclusion supported by these results is that the child protection system should be regarded and developed as a systematic project combining the legal, policymaking, and professional systems of child welfare services as well as governmental and non-governmental forces. As the COVID-19 pandemic has raised awareness of the need to develop the field of child protection holistically as an integrated system in terms of social sustainability in China, an international literature-based comparison indicates that the pandemic has also raised similar political awareness in other countries.

AbstractSustainable development of container terminals is based on energy efficiency and reduction in CO2 emissions. This study estimated the energy consumption and CO2 emissions in container terminals according to their layouts. Energy consumption was calculated based on utility data as well as fuel and electricity consumptions for each container-handling equipment in the container terminal. CO2 emissions were estimated using movement modality based on the number of movements of and distance travelled by each container-handling equipment. A case study involving two types of container terminal layouts i.e. parallel and perpendicular layouts, was conducted. The contributions of each container-handling equipment to the energy consumption and CO2 emissions were estimated and evaluated using statistical analysis. The results of the case study indicated that on the CO2 emissions in parallel and perpendicular layouts were relatively similar (within the range of 16–19 kg/TEUs). These results indicate that both parallel and perpendicular layouts are suitable for future ports based on sustainable development. The results can also be used for future planning of operating patterns and layout selection in container terminals.
