Abstract: This paper analyzes Uganda’s electricity distribution network performance gaps and modernization challenges using Kampala West region’s Kitala feeder as a case study. Industry-standard reliability indices including System Average Interruption Duration Index (SAIDI), System Average Interruption Frequency Index (SAIFI), Customer Average Interruption Duration Index (CAIDI), modernization maturity assessment, and network simulations identified high outage durations, frequent interruptions, and significant feeder losses. Modernization interventions including protection coordination, network reconfiguration, reconductoring, parallel circuits, and distributed generation significantly improved reliability and reduced losses. Cost-benefit analysis using Net Present Value (NPV) and payback period metrics highlighted the most economically viable interventions. The study recommends targeted interventions with optimal NPV and payback period values, replicable to similar urban feeders across Sub-Saharan Africa. Policy formulation and regulations supporting comprehensive distribution network modernization are essential to achieve reliable electricity supply and supportUganda’s Vision 2040 goals.

Abstract: Electric power supply is one of the most important aspects of China’s national energy development strategy (NEDS). As major economic unit as well as major energy consumer, Jiangsu province is facing serious energy supply challenges. Under such circumstances, positive actions are taken by local government in respond to NEDS which put energy saving in the first place, and demand side management (DSM) is implemented. DSM is an important measure which can release rush hour electric supply pressure, enhance energy efficiency, optimize electric power utilization, and it is beneficial for sustainable development. This paper is based on the analysis of the current DSM situation of Nanjing, and green lighting is taken as an example. An empirical analysis is given to cost-effectiveness of the implementation of green lighting. Finally, the conclusion that the cost-effectiveness of the implementation of green lighting is economically viable to power supply companies, electric customers and the whole society is drawn.

Abstract: The cost and benefits have been analyzed of applying SM570 steel to tall buildings in Taiwan. In detail, two 40-story steel buildings are designed for the Taipei Microzonation II. One building has SN490B steel columns. The other also uses SM570 steel for the 1^st -to- 14^th -story columns. The stress ratios and story drift ratios are limited to 0.9 and 0.005, respectively. The drift demands are then evaluated by using nonlinear time history analyses with 14 sets of ground motions scaled to the intensity for the return periods of 475 and 2500 years. By FEMA 356, the building fragility is further assessed using the drift ratios of 2.5% and 5% for life safety and collapse prevention. It is concluded that the use of SM570 steel saves 140 tons steel in total, approximately 3%. That also reduces the seismic drift demands of the building, greatly decreasing the failure probability against earthquake collapse.

Abstract: This paper explored cost-benefit analysis in the economic assessment of environmental impact of construction projects, proposed the objects and methods of economic evaluation of environmental impact, constructed a comprehensive evaluation indicator system. The indicator system reflected external economic characteristics of construction project environmental impact. Finally, this paper introduced the indicator algorithm, achieved the environmental impact measurement of monetization.

Abstract: The main reason for slow development of energy-saving buildings are differences in the benefit of all stakeholders to appeal. Identifying stakeholders, and on the basis of analysis all parties interests and needs, energy-saving building Life Cycle Cost-Benefit Model was established. Then we can find the equilibrium point among the government, developer and consumer, and factors of impacting the development of energy-saving buildings. Last we provide advice for the rapid development of energy-saving buildings.

Abstract: In the present work the economic feasibility of a project of public infrastructure, the expansion of the subway of the city Potenza, is estimated. The assessment has been developed through the application of the Cost-Benefit Analysis. As is known the advantage of this technique is the ability to express in monetary terms the externalities (positive and negative) generated by the project. In this case, the external cost savings related to the improvement of the mobility in the city have been internalized. The research has shown that the valuation of the externalities can be an effective way to manage the planning of new public transport infrastructure.

Abstract: Fossil fuel burning for energy production creates two major issues: the global warming effect and the weak energy security. These problems can be minimized by utilizing renewable energy sources such as biomass. In order to assess the potential contribution of these technologies to the future energy security and sustainable development, a thorough evaluation of gasification technology towards economic aspects is required. This study aims to determine whether the syngas production from EFB gasification for electricity generation is viable in terms of cost-benefit analysis by evaluating the economic aspects of these technologies.

Abstract: Since reform and opening up for more than 30 years,tremendous progress in human development has been made,while also facing the double pressure of energy shortage and environmental pollution. Based on this situation,government has introduced a series of energy conservation and emission reduction policies.Therefore, energy saving has aroused widespread concern. Policy research on the implementation of energy saving has become a hot issue of academia.In this context,evaluation of energy-saving emission reduction policies has important theoretical and practical significance.It can provide theoretical support and decision for the state making energy-saving emission reduction policies.

Abstract: Demand-side management is a long-term strategic systems engineering which consistent with sustainable development requirements. According to the process of power companies and users participant of demand-side response, this article constructs the demand-side response with the principle of maximize benefits, while taking a regional electricity load as an example, which analysis the changing relationship between electricity price, incentive measures and users demand based on the measurements implementation of price and stimulating two demand-side responses of this area.

Abstract: Project environmental impact assessment theories and residential project reality closely, to study on the environmental impact assessment of deep.
