Item type:Publication, Energy efficiency of buildings review in 2016(University Politehnica Timisoara, Faculty of Engineering Hunedoara, Romania, 2018); The Energy Performance of Buildings Directive (EPBD) is the European Union’s main legislative instrument aiming to promote the improvement of the energy performance of buildings within Community. It was inspired by the Kyoto Protocol which commits the EU and all its parties by setting binding emission reduction. The first version of the EPBD (Directive 2002 /91/EC), was approved on 16 December 2012 and entered into force on 4 January 2003. The Directive required the MS strengthen the building regulations and introduce Energy Performance Certificates (EPCs). Directive 2002/91/EC was later on replaced by the so-called “EPBD recast”, which was approved on 19 May 2010. This version of the EPBD broadened its focus on nearly Zero-Energy Buildings (nZEB), cost optimal levels of minimum energy performance requirements as well as improved policies. 2016 is an important year for energy efficiency legislation at EU level, with the upcoming revisions of the EPBD and Energy Efficiency Directive (EED). On 30 November 2016 published its “Clean Energy for All Europeans“ package, also known as the “Winter Package”. With an appropriate framework, buildings could play a central role in transforming the EU energy system. Buildings are entering a transition phase, transforming into highly efficient micro energy-hubs consuming, producing, storing and supplying energy, making the system more flexible and efficient enabling a rapid uptake of renewable energy and electric vehicles. The Paris Agreement provides a common framework within which individual countries are invited to define nationally determined contributions (NDCs) taking account the overall goal of the UN Framework Convention on Climate change. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Methodology for techno–economic optimization of solar assisted heating systems(University Politehnica Timisoara, Faculty of Engineering Hunedoara, Romania, 2018); ; This paper has objective, to estimate the thermal performance of solar assisted heating systems in regard of solar fraction and perform life cycle cost analysis to assess the feasibility of their implementation in residential sector. In general it is known that the resource for solar thermal systems i.e. the solar irradiation is free, but the equipment to collect it and convert in to useful form (heat or electricity) has a cost. Solar thermal systems are characterized by high investment and low operational cost. It is presented methodology for obtaining the right size of a solar thermal assisted heating system that gives the lowest combination of solar and auxiliary energy costs. Thermal performance of the solar thermal systems are estimated using numerical methods and software since the solar processes are transient in nature been driven by time dependent forcing functions and loads. The system components are defined with mathematical relationships that describe how components function. They are based on first principles (energy balances, mass balances, rate equations and equilibrium relationships) at one extreme or empirical curve fits to operating data from specific machines. As a result of the analysis specific indicators are derived in order to facilitate the techno–economic analysis and design of solar assisted heating systems - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Techno-economic and environmental optimization of heat supply systems in urban areas(National Library of Serbia, 2018); ; The present work deals with an optimization model for selection of optimal heating structure in urban areas also considering the environmental aspects. The optimization model was established in order to facilitate the decision making during selection phase of heat sources locations and defining the boundaries of their action at the predesign phase of heat supply schemes development of settlements. Within the model is performed comparative analysis between ten heating systems, whereas as leading criteria in the comparison procedure are considered heat load density per unit of area, techno-economic aspects, and environmental impact. The optimization result actually defines the optimal heating system type in regard of the heat load density per unit area. The model provides possibility in defining standard values of heat density indicators, according to which can be assessed the economic feasibility of implementing district heating system for the selected urban area. The less value of heat density in the system, the higher specific costs for generation, distribution, and transmission of heat energy. Further-more, the model is applied and verified for the local urban, infrastructural, technical and environmental conditions of the city of Skopje. The process of determination of optimal heating structure has holistic approach, where, beside techno-economic aspects and feasibility, the environmental aspect of different heating systems is considered as a major factor (threat) in air pollution. - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Environmental protection and industry: Parameters necessary for environmentally related decision making(Part of the NATO Science for Peace and Security Series C: Environmental Security book series (NAPSC) © Springer Science + Business Media B.V. 2009, 2009)Nošpal A., Lazarevska A. M.Industry, as one of the economy pillars, is to be accounted for the development and improvement of a certain country's well-being. Unfortunately, the prosperity has and still is accompanied with direct and/or indirect negative environmental impact, especially in the Western Balkans countries with economies in transition. In this chapter, we focus on the parameters necessary to identify, describe, parameterize, monitor and prevent pollution deriving from industry for the purpose of alleviating the process of decision making relevant to environmental protection. Illustrated are examples from several industrial sectors including energy generation, public transportation, cement industry and ferrous metallurgy
