A proper infrastructure assessment in the contemporary engineering world has become very crucial due to the palpable resources challenges. Therefore, from the design, construction, operation and maintenance stages of the built infrastructural systems; cognizance must be taken of the associated factors and their significance. In considering these indices, the experts will save lots of resources wastage thereby integrating new technologies into the full life cycle of the infrastructure. In this paper, two sets of building infrastructure professionals were assessed. These are the corporate building organization （CBO） and the Operators from two shopping malls within the UK. Thirty-four factors regarding the sustainable building infrastructure appraisal were identified through literature reviews. These characteristics were accordingly classified into two factors （group I and II） and a comparative analysis of their influence conducted. Priority rating of the factors assessment on building infrastructure was through structured, administered survey amongst professionals within these organizations. Information of this survey revealed that the experts maintained a strong concordance in rating these factors. As a result, the associated factors have relatively substantial degree of influence in this context. Further indications of the result in groups I and II are that the CBO experts have indicated the infrastructure size, planning and design as the key factors. Also, the type of building characteristic was among others as the top and bottom marked cases. Similarly, the Operators too have maintained that a proper infrastructure design should incorporate a good policy framework for efficient energy saving fixtures and conservation. Additionally, the installation of quality equipment promotes cost savings of the resources and a just-in-time maintenance of the infrastructure at large. The maintain as-we-go philosophy characteristic was not strongly encouraged in this case.

The ever-increasing human population has resulted in political pressure to increase crop production. Currently, smallholder farmers are expected to be environmentally considerate, adapt to extreme climatic conditions and deal with financial instability. Despite these recent developments, farmers and their farming activities in these rural environs of developing countries need to improve household food and income security on a sustainable basis. A minimum data set selected from extensive data was used to determine indicators for soil sustainability assessment. This method involved expert opinion and statistical data reduction techniques. The results indicated that SOC, MBC, BS, EC, Spo and sand were the most important variables selected as MDS using PC analysis. Forest and Grassland had a high sustainability index (SI) while Savannah woodland, Fallow and Cropland were rated not sustainable (NS). For Cumulative rating using the total dataset (CR-TDS), Forest had a high sustainability index (HS), Savannah woodland and Grassland were sustainable (S) compared to Fallow and Cropland, which were sustainable with high input (SWHI). Also, for cumulative rating using the minimum dataset (CR-MDS), Forest, Savannah woodland and Grassland had high sustainability (SH) indices compared to Fallow and Cropland, which were considered sustainable with high input (SWHI). sustainability index (SI) and Cumulative rating (CR) using the total dataset (CR-TDS) had a strong correlation (R2 = 0.91, p 2 = 0.44, p 2 = 0.60, p sustainability assessment.

Construction equipment encompasses highly polluting machines adversely affecting the *** tools are necessary for sustainability assessment of construction equipment fleets to allow contractors to reduce their emissions and comply with local or federal regulations. In addition to management tools, there is a need for a metrics that will allow companies to accurately assess the sustainability of their construction equipment fleets. The State of California USA is adopting innovative approaches to reduce adverse impact of humans on the environment. Once successfully implemented, the chances are that such practices attract other states to adopt similar approaches. This paper presents an evaluation of construction equipment fleets and data analysis. When measured and recorded, such results can be used along with decisionsupport tools for selection and utilization of construction equipment. The metrics for construction equipment evaluation as well as the tool for sustainable decisionmaking are developed based on readily available data from manufacturers or maintenance shops without a need for additional effort by contractors or government agencies for their adoption. The metrics developed and the decision support tool incorporate logical strategies of supply chain management for optimal selection of construction equipment for construction site while taking into account the availability, cost, and mobilization related constraints. The metrics and the model can benefit both the government agencies responsible for inspection of fleets and owners of construction companies in their decision-making processes related to environmental sustainability.

Journal of Energy and Power Engineering 2011年第6期5卷 542-547页

作者： R.P. Mendes L.C. Goncalves P.D. Gaspar Electromechanical Engineering Department Engineering Faculty University of Beira Interior Covilha 6201-001 Portugal

The conversion of solar energyinto electricity reveals a huge importance in the production of＂clean＂ energy, mainly when applied to decentralized production systems （micro-generation）. However, there is the need to develop and optimize these processes in order to turn it more sustainable in economic and technological scoops. The main purpose of this work is to study the solar energy conversion into electricity through photovoltaic cells, characterizing the process efficiencies. This study intends to evaluate the energetic and exergetic efficiencies defining them as indicators in the formulation ofa sustainability index. All the procedures are in a theoretical scope with an illustrative example in the end of this work.
