With the increasing demand for clean and low-carbon energy, high proportion of renewable energy has been integrated into the receiving-end grid. The grid-side energy storage project can ensure the safe and stable operation of the grid, but it still faces many problems, such as high initial investment, difficult operation and maintenance, unclear profit model, lack of business mode. Therefore, it is of great significance to evaluate the comprehensive benefit of energy storage projects in order to guide the sustainable development of large-scale energy storage projects and power system. By studying the technical and economic characteristics of energy storage, this paper establishes a comprehensive evaluation system from four dimensions of energy efficiency, economic, social, and environmental benefit. Combined with typical business modes and determining the subdivision index system of different modes, the comprehensive benefit evaluation model of grid-side commercial storage project based on Fuzzy-Analytic Network Process (ANP) approach is established. Empirical analysis of a 100-megawatt storage project is carried out to evaluate the project benefits comprehensively, the potential problems of the market development and business mode of the grid-side large-scale storage project are discussed, and the future development orientation and suggestions are put forward.

Combined heat and power generation is also called the heating reconstruct project, comprehensive benefit evaluation of heating reconstruction project provide a more scientific basis for project construction and project operation, strengthen scientificalness for decision-making , avoid investing blindly and improve investing returns of the project. To begin with, it is emphasize on the analysis of the project whole, and then established evaluation index system and comprehensive evaluation model based on financial and non-financial data collecting of the project. At the third, evaluating the financial feasibility, project environmental benefit and social benefit evaluation of the heating reconstruction project. Eventually, it comes to a conclusion for a validation of heating reconstruction project feasibility.

The emergence of prefabricated buildings is helpful to solve the problems of serious energy consumption and environmental pollution in traditional cast-in-place buildings. However, the current unclear benefits of prefabricated buildings have led to great constraints on its development in China. Therefore, in order to clarify the comprehensive benefit level of prefabricated buildings and promote the development of prefabricated buildings, the comprehensive benefits of prefabricated buildings are analyzed from four aspects of economy, environment, society, and security, and 19 evaluation indexes of economic benefits, environmental benefits, social benefits, and safety benefits of prefabricated buildings are selected from the life cycle dimension in this paper. The comprehensive benefits of prefabricated buildings are constructed by using set pair analysis theory. Finally, through the analysis of the prefabricated building project in Hefei, the feasibility of the model was verified, and comprehensive benefit level of prefabricated buildings in Hefei was further judged. This paper provides a feasible and operable evaluation model for the comprehensive benefit evaluation of prefabricated buildings and also provides a theoretical support for the development of prefabricated buildings.

Multiple benefit evaluation may become complicated due to varied and unquantifiable indicators. This study presents a multicriteria approach to evaluate Low Impact Development (LID) performance through an aggregation of principal component analysis and correlation analysis (PCCA). The approach is based on the rule of triple bottom line and complies with the China-specific planning land-use type and site-specific hydrologic and hydrologic condition. The quantitative indicators are coupled with the Stormwater Management Model (SWMM) software and filed investigation; the qualitative indicators are valued by a numerical unit system that converts the level of importance to numbers 5, 4, 3, 2 and 1. The results indicate that the PCCA approach could evaluate the LID performance with fewer dimensions of variables based on environmental, economic and social concerns comprehensively. The principal components concentrated on three streams: (1) runoff quantity and quality control; (2) minimize cost and improve robustness; and (3) improve system management and aesthetic enhancement. Taken together, these streams match the objective of sponge city construction with LID techniques. The PCCA approach is a multicriteria decision-aid tool that helps the decision maker choose the appropriate LID technique.
