Abstract:

The paper explored the urgent needs of scientific development practice and economic development pattern transform. The integrated economic effectiveness of energy conservation and intensity decrease were analyzed,and the economic rationality of energy conservation priority strategy was identified. The paper assessed the integrated economic benefit of energy conservation effort during the "11th Five-Year Plan"  period. With data and facts, it was approved that the energy conservation efforts achieved great economic benefit. The paper analyzed the macro-economic effectiveness contributed by efforts of energy conservation in the "12th Five-Year Plan"  period to support the transform of economic development pattern, and to achieve long term sustainability of economic growth.

Effects of design parameters on rooftop photovoltaic economics in the urban environment: a case study

Hongying ZHAO, Rebecca YANG, Chaohong WANG, W. M. Pabasara U. WIJERATNE, Chengyang LIU, Xiaolong XUE, Nishara ABDEEN

Frontiers of Engineering Management 2019, Volume 6, Issue 3,   Pages 351-367 doi: 10.1007/s42524-019-0023-6

Abstract: Many researchers found high potential of adopting building photovoltaic (PV) systems in urban areas, especially on building rooftop, to improve the sustainability of urban environment. However, the optimal energy output performance and economic benefit of the PV system are affected by the usable roof area, PV array layout, and shading effect considering high city density. This study aims to understand the effects of these design parameters in the urban environment of rooftop PV’s economic performance. This study carries out a case study in the urban area of Melbourne with 90 PV designs under three shading conditions to generate 270 scenarios. Through a lifecycle cost-benefit analysis, including net present value (NPV), NPV per kW, internal return rate (IRR), and payback year, the results can help in developing a comprehensive understanding of the economic performance of rooftop PV designs that cover most of the urban areas of Melbourne. The optimal PV design scenarios for the urban environment are identified, thereby providing investors and industry professionals with useful information on value-for-money PV design. Meanwhile, the maximum shading loss that makes the PV systems financially unfeasible is investigated, and design scenarios with greatest ability to sustain the shading effect are identified. This research can also support the policy makers’ decision on the development and deployment of the roof PV systems in urban planning.

The Building of Papermaking Enterprise’s Recycling Economy Evaluation Index System Based on Value Flow

Zhi-fang Zhou,Jing Ou,Sha-sha Wang,Xiao-hong Chen

Frontiers of Engineering Management 2016, Volume 3, Issue 1,   Pages 9-17 doi: 10.15302/J-FEM-2016009

Abstract: At present, the research on circular economy has made a lot of substantive results both at home and abroad. But for the papermaking enterprise, which is the representative of the light industry, few studies have analyzed the evaluation index system of circular economy. Since the current material flow analyses have limitations that the researchers cannot calculate materials with different units. The authors take advantage of the intrinsic correlation between the basic principle of value flow analysis and circular economy, and then analyze the dynamic changes of material flow and value flow through enterprises internal production process. Considering the resource output, the authors set up the layered structure of the evaluation index system, and then preliminarily determine the index form. Next, the authors use the frequency statistics analysis method to adjust indicators, forming a preliminary index system. After that, the principal component analysis and independent analysis are applied for screening. Finally, the authors build a circular economy evaluation index system for papermaking enterprise to provide scientific guidance for the process of circular economy.
