2015
Bakalaura darbs “Armēnijas dalības izvērtējums ES Austrumu partnerībā un Eirāzijas Ekonomiskajā savienībā” sniedz ieskatu par starptautiskās sadarbības un ekonomiskās integrācijas procesiem, kā arī Armēnijas dalību divos projektos – Austrumu partnerībā un Eirāzijas Ekonomiskajā savienībā. Darba gaitā tiek noskaidrotas Armēnijas priekšrocības no dalības šajos procesos. Darbā tiek sniegta informācija par sadarbības veidiem un ekonomiskās integrācijas teorijas attīstību. Salīdzinoši tiek analizēta ES Austrumu partnerības un Eirāzijas Ekonomiskās savienības struktūra. Pētījums tiek veikts izmantojot ekspertu interviju metodi, lai saņemtu un izpētītu informāciju attiecībā uz Armēnijas sadarbības…

Darba mērķis ir novērtēt ekonomiskos drošības riskus ES un Ķīnas ekonomiskajās attiecībās. Maģistra darbā tiek analizēti avoti par ekonomikas un drošības mijiedarbību un ekonomiskās drošības veidojošiem faktoriem un riskiem. Autors apskata Ķīnas ekonomisko izaugsmi, tās ārējo ekonomisko politiku un tās ietekmes piemēriem pasaulē. Darba noslēgumā ir secinājumi un priekšlikumi par ekonomiskās drošības riskiem ES un Ķīnas ekonomiskajās attiecībās, balstoties uz ES ekonomikas ievainojamības un noturības, kā arī ES un …
The determinants of employees’ investments in their company share
2007
Our research is motivated by an observation. Employee Ownership is a form of savings that is becoming moreand more sought after these days. The concentration of the employee savings into employee ownership isbecoming stronger. These evolutions translate into a fact: employees facing a savings menu tend to chooseEmployee Ownership. The high exposure to risk of the employee-shareholders might have some consequence fortheir assets and their job. For companies, the cost of this exposure to risk can also be high. These observationshave led us to wonder about the causes of employees’ investments in their company stock. Thus, this researchtries to answer the question: Which are determinants of emp…
Brief description of current research activities on energy saving by cogeneration and thermoeconomic analysis and diagnosis of energy systems
2014
In the last decades the severe issues related with fossil fuels depletion, increasing energy prices and global warming impact of energy conversion systems have attracted the efforts of scientists toward efficient technologies and methodological improvements for a rational use of energy both in the civil and the industry sectors. Among the numerous research lines developed, the combined production of multiple energy vectors and the process integration are widely considered very promising solutions to achieve more sustainable scenarios as concerns the use of energy. While polygeneration in industry represents a well-established practice to reduce the production cost of energy and material str…
GLOBAL SAVING EVALUATION THROUGH A RETROFITTING ACTION
2014
The paper shows a work that was carried out by the authors as members of the PADesign Company, academic spin off of University of Palermo. Currently, energy retrofit of existing building has become an important goal, because it is now widely recognized that the buildings are one of the main causes of CO2 production and of non-renewable energy consumptions. To act on the energy performance of existing buildings (adapting their performances to those required by regulations) is an important strategy to reduce energy consumptions since they are much more than new buildings. Through the application of innovative technologies and methodologies and the choice of appropriate investments, the retrof…
CHP (combined heat and power) retrofit for a large MED-TVC (multiple effect distillation along with thermal vapour compression) desalination plant: H…
2016
Abstract Integrated power plants in “dual purpose” configuration may represent a viable option for energy cost abatement of desalted water produced by MED-TVC (Multiple Effect Distillation along with Thermal Vapour Compression). In this paper an existing large MED-TVC plant with a 36,000 m 3 /day capacity is studied: a plant retrofit is designed, based on a steam power plant with condensation and steam extraction used to drive the steam ejector. As the plant operates in CHP (Combined Heat and Power) mode, the possibility to assess the integrated “CHP + MED-TVC” as high efficiency cogeneration according to Directive 2004/8/EC is discussed. Based on a model developed in Engineering Equation S…
Energy-environmental and cost assessment of a set of strategies for retrofitting a public building toward nearly zero-energy building target
2017
Abstract The purpose of this study was to assess an energy retrofit of a building representative of those in public tertiary stock, to improve energy performance toward nearly Zero-Energy Building (nZEB) requirements. The building is located in the campus of the Politecnico di Milano University (Italy). Several hypothetical improvements regarding the building envelope and plants were assessed in terms of energy savings, costs, and the reduction of greenhouse gas emissions. The results of the study show that it is possible to reduce primary energy demand and associated emissions up to 40% from the current values by adopting market-available and well-proven technological solutions for retrofi…
An Overview on Solar Shading Systems for Buildings
2014
Abstract In recent years, different types of solar shading devices have been proposed, depending on building orientation, location, window characteristics, etc. They can contribute to improve or worsen building thermal and lighting performances both from an energy and comfort point of view. The present paper reports a critical analysis of some studies that investigate shading devices’ effects on building thermal and/or lighting performances. This article points out the difficulty in comparing the different results given the lack of uniformity between the studies, since they analysed buildings with different characteristics, locations and using various indices. Therefore a protocol to carry …
Building green covering for a sustainable use of energy
2013
Nowadays the growth of the cities increased built and paved areas, energy use and heat generation. The phenomenon of urban warming, called urban heat island, influences negatively outdoor comfort conditions, pollutants concentration, energy demand for air conditioning, as well as increases environmental impact due to the demand of energy generation. A sustainable technology for improving the energy efficiency of buildings is the use of green roofs and walls in order to reduce the energy consumption for conditioning in summer and improve the thermal insulation in winter. The use of green roofs and walls can contribute to mitigate the phenomenon of heat island, the emissions of greenhouse gas…
