Assessment Index System

Presently the sustainable development stratagem has made the green buildings to be a trend of building industry in China, and the assessment to the green buildings is becoming more and more important in developing the green buildings. In this paper the meaning of the green building assessment is explained, several main domestic and foreign green building assessment systems are analyzed and compared, and the common ground and limitations of these assessment methods are presented. Then a novel assessment index system which is more comprehensive, scientific and suitable for green buildings in China is developed by using the life cycle assessment method. This system contains six categories including land saving and outdoor environment, energy saving and utilization, material saving and utilization, water saving and utilization, indoor environment quality and economy. According to the decision-making stage, design stage, construction stage, operation and maintenance stage, each category is divided into more concrete indexes. At last the established assessment system is used to evaluate a typical building in Xi’an, China. The final novel assessment index system is of theoretical and practical significance for the assessment and development of green buildings in China.

Smart grid must be evaluated correctly so that its development stage is determined and weak links, restrict factors in development are found. Based on it, the path from the stage to the next stage is planned for power enterprises. In view of the poor accuracy of conventional assessment methods, caused by subjective factors and uncertainty, the fuzzy comprehensive assessment method is applied to assess smart grid. Firstly, a smart grid assessment system is founded based of IBM’s smart grid maturity model, and then method and procedure of fuzzy comprehensive assessment method are introduced. The study on an example shows that this approach is effective and feasible.

The Impact

Green buildings refer to buildings that decrease adverse environmental effects and maintain natural resources. They can diminish energy consumption, greenhouse gas emissions, the usage of non-renewable materials, water consumption, and waste generation while improving occupants’ health and well-being. As such, several rating tools and benchmarks have been developed worldwide to assess green building performance (GBP), including the Building Research Establishment Environmental Assessment Method (BREEAM) in the United Kingdom, German Sustainable Building Council (DGNB), Leadership in Energy and Environmental Design (LEED) in the United States and Canada, Comprehensive Assessment System for Built Environment Efficiency (CASBEE) in Japan, Green Star in Australia, Green Mark in Singapore, and Green Building Index in Malaysia. Energy management (EM) during building operation could also improve GBP. One of the best approaches to evaluating the impact of EM on GBP is by using structural equation modelling (SEM). SEM is a commanding statistical method to model testing. One of the most used SEM variance-based approaches is partial least squares (PLS), which can be implemented in the SmartPLS application. PLS-SEM uses path coefficients to determine the strength and significance of the hypothesised relationships between the latent constructs.

This paper proposes some suggestions to perfect our current green building assessment system. Green building and ecological building is undoubtedly the trend of construction industry. Green building assessment systems play a directional function for the design, the construction and the use of green architecture. This paper introduces the development of green building assessment system at China and other country firstly. Through the comparison and analysis for some kinds of green building assessment systems, found that that the applicability for buildings and areas and the fairness for ecological environment and surrounding people of current assessment system should be optimized. Finally，proposed that several aspects must be considered, and thus establish the new system-A Green Building Assessment Method Which Based on the Environmental Disturbance and Ecological Compensation.

Abstract Southern stem rot (caused by the soilborne fungus Sclerotium rolfsii Sacc.) of peanut (Arachis hypogaea L.) traditionally has been assessed based on the percentage of infected 30.5-cm row segments, commonly referred to as disease incidence. Several alternative disease assessment methods were evaluated in four fungicide trials during the growing season (aboveground ratings) and immediately after peanut inversion (belowground ratings). Pearson's correlation coefficients compared disease assessments and yields for all trials. Across all disease assessment methods, belowground assessments at inversion showed a stronger correlation with yield than in-season aboveground assessments. Several of the alternative assessment methods showed a stronger negative correlation with yield than did the traditional disease incidence rating. However, none of the alternative methods were consistently more precise across all assessment dates and trials. There was a significant positive correlation between many of the alternative methods and the traditional disease incidence method. Furthermore, none of the alternative methods was better than the traditional method for detecting differences among fungicide treatments when subjected to ANOVA and subsequent Waller-Duncan mean separation tests (k-ratio = 100). Based on comparisons of the time required to assess disease intensity, the traditional disease assessment method was found to be the most time efficient method of those tested in this study.
