Monitoring Results and Energy Performances Evaluation of Freescoo Solar DEC Systems
2016
Abstract This work addresses the energy saving performances of some solar Desiccant and Evaporative Cooling (DEC) systems working with the freescoo technology. The innovative freescoo concept is based on the use two fixed and cooled adsorption beds and advanced indirect evaporative cooling processes. The main feature of this new adsorption bed concept is to allow the simultaneous dehumidification and cooling of air. The systems analyzed have been installed in Italy last here and results based on field monitoring data are here presented. A description of the monitored systems and comparisons between the energy performances based on the main performance indicators such as EER, thermal COP, co…
An Exploratory Study of Financial Performance in CEE Countries
2020
Our research investigates the performance of companies from Central and Eastern European (CEE) countries in the period after the Global Financial Crisis of 2007-2009 with the aim of identifying the driving factors behind accounting- and market-based performance. We include in the analysis companies from various industries in CEE countries that are European Union members and we study their performance between 2008-2016 over the following areas of performance: liquidity, solvency and indebtedness, operational profitability, global performance (through Return on assets and Return on equity), returns available to shareholders and market-based performance (through price/book value and Tobin Q …
Assessing the sustainability of water companies: A synthetic indicator approach
2016
Performance indicators (PIs) are essential in the benchmarking process used to rate and rank water companies. However, a set of individual PIs does not provide a holistic assessment of company performance from multiple perspectives. A multidimensional evaluation of the performance of water companies can be achieved by aggregating the PIs into a synthetic indicator. Although the concept of sustainability involves economic, environmental and social criteria, most of the previous studies have not considered these three dimensions simultaneously. This paper discusses a process of indicator aggregation using two approaches based on multi-criteria decision analysis to evaluate and compare the sus…
Environmental performance: an index number approach
2004
Abstract Tyteca [J. Environ. Manage. 46 (1996) 281] reviews the literature on environmental performance indicators. In that paper he calls for an index that simultaneously accounts for resources used, good outputs produced and pollutants or undesirable outputs emitted. Here, we provide a formal index number of environmental performance which can be computed using data envelopment analysis (DEA) techniques. The implicit benchmark is that of finding the highest ratio of good to bad outputs. Our environmental performance index is constructed from distance functions which implies that it satisfies a number of desirable properties. Since the component distance functions require only information …
Is the environmental performance of industrialized countries converging? A ‘SURE’ approach to testing for convergence
2008
In this paper, we test for convergence in the environmental performance of a sample of OECD countries, with data ranging from 1971 to 2002. First, we use Data Envelopment Analysis (DEA) to compute two environmental performance indicators (EPIs) in the production theory framework. Second, we propose the use of a sequential multivariate approach to test for convergence in environmental performance. These tests allow us to reconcile the time series literature with the cross-sectional dimension, which is basic when testing for convergence in regional blocs. The SURE technique is used, which allows for the existence of correlations across the series without imposing a common speed of mean revers…
Economic and environmental performance of wastewater treatment plants: Potential reductions in greenhouse gases emissions
2014
Abstract Sanitation and wastewater treatment are essential for protecting human health and environmental sustainability. Treatment processes are not free of environmental impacts; consequently assessment of the environmental performance of wastewater treatment plants (WWTPs) has gained interest in recent years. Unlike other methods, a direct approach is followed to estimate environmental performance indicators (EPIs) using data envelopment analysis (DEA), i.e. an index of overall performance is directly obtained. The present study represents pioneering work to integrate environmental impacts in the assessment of the efficiency of WWTP estimating pure (PEPI) and mixed (MEPI) environmental pe…
Institutional Logics in Police Performance Indicator Development : A Comparative Case Study of Spain and Finland
2015
Police performance is not easily measurable and the organization and circumstances of police work vary among European countries. Further, police work is surrounded by multiple pressures to make it both economical and effective. Consequently, there are multiple institutional logics in decision-making which may affect the selection and the use of police key performance indicators (KPIs). The KPI selection and use processes reflect the institutional logics, though KPI use may also sometimes influence the institutional logics of police work. In this study, we analyze the KPIs and institutional logics in police work in Finland and Spain. A comparative case research approach is used in order to h…
Multicriteria performance analysis of an integrated urban wastewater system for energy management
2017
AbstractThe optimization and management of an integrated urban wastewater system is a complex problem involving many processes and variables. The possible control options are defined by several management strategies that may differently impact the economic, operational or environmental performance of the system. The present paper aims to contribute to the environmental and energy sustainability of urban wastewater systems by means of a multicriteria performance analysis. The paper begins with a complete analysis of the system performance in several fields of interest (energy, environment, quality of service, operation, economy and financial resources), and it highlights the management stren…
Identification of Defensive Performance Factors in the 2010 FIFA World Cup South Africa
2016
The aim of this study was to determine the efficacy of defensive play in elite football, to identify variables associated with the direct recovery of ball possession, and to propose a model for predicting the success of defensive transitions. We analyzed 804 transitions in the final stages of the Fedération Internationale Football Association (FIFA) World Cup 2010, and investigated the following variables using univariate, bivariate, and multivariate analyses: duration of defensive transition, possession loss zone, position of players at the start and end of the defensive transitions, defensive organization, general defensive approach, time of the match, position of defense, zone in which t…
Performance Measurement Framework with Formal Indicator Definitions
2011
Definition of appropriate measures of organization’s performance should be conducted in a systematic way. In this paper the performance measurement and indicators are discussed not only from the side of management models, but also from the point of view of measurement theories to find out appropriate definitions. In our work we propose a formal specification of indicators. The principles of indicator reformulation from free form indicators to formal requirements are formulated and applied in several examples from performance measures database. The formally defined indicators could be used in the proposed performance measurement framework that covers five-step indicator lifecycle.
