    Ecologic impact analysis of construction materials
    (Batman Üniversitesi, 2018-12-28) Balo, Figen; S.Sua, Lutfu
    This research’s purpose is to assess the ecological effect produced by the building materials, by means of the ecological impact analysis implementation. The study aims to investigate the ecological impact of the main construction materials based on various criteria exist in the literature. The effect of eight different fundamental construction materials (glass, shingles, ceramics, iron-steel, wood, concrete, copper, aluminum) on the environment is of big concern and environmentally conscious designed constructions are essentially demanded. By considering the construction materials’ nine different environmental impacts (photochemical oxidation, terrestrial eco-toxicity, freshwater aquatic eco-toxicity, human toxicity, stratospheric ozone depletion, climate change, water demand, global warming potential, primary energy demand) and two other physical properties (density, thermal conductivity), a comparison between the alternatives is presented based on the mentioned criteria. Finally, the ecofriendliest construction material based on the criteria is determined.

    Life-cycle environmental footprint analysis of electricity generation technologies
    (Batman Üniversitesi, 2019-05-23) Balo, Figen; S.Sua, Lutfu
    Increasing urbanization and global population, in addition to huge economic and industrial developments have jointly led to raised consumption of electrical. With the rise in fossil-based fuel costs and the environmental awareness to decrease greenhouse gas emissions there is an increasing requirement to alter away from CO2 emission creating fossilbased fuels to new renewable power resources for electrical generation. By using Life Cycle Assessment, this paper’s scope is to compare and evaluation the chosen environmental effects associated with the electrical generation of the sustainable and the fossil-based system. In this paper, the environmental footprint that obtains from the diverse energy sources’ exploitation/use, either renewable or conventional/fossil in the electrical generation industry, is analyzed. Analysis of the electrical energy generation sectors depended on diverse factors include a potency ecological effect categories’ wide vary. Thus, the energy sources’ diverse life cycle stages used in electrical generation are investigated. The pairwise comparison is presented for the needed data’ derivation. For each of criteria, these comparison is applied for deriving weights of criteria’ significance and alternatives’ relative rankings. Each technology’s ecological effect according to all factors are calculated. Finally, the ecofriendliest and the most environmentally damage technologies are determined.
