This paper aims to assess the environmental impact of family houses designed as a building with green technologies and green materials. These family houses are located in villages of Velky Folkmar and Jedlinka, which are situated in eastern Slovakia. The analysis investigates the role of application of these technologies on impact categories such as: global warming potential (GWP), acidification potential (AP), eutrophication potential (EP), photochemical ozone creation potential (POCP), abiotic depletion potential fossil fuels (ADPF) expressed as CO2eq, SO2eq, PO43−eq, kg ethylene and MJ, respectively within “Cradle to Grave” boundary by using the LCA assessment method. The main contribution of the study is to highlight the significance of green technologies in reduction of environmental impacts. The presented results show that house with built-in green materials and technologies causes significantly lower environmental impacts compared to house where both green technologies and conventional materials are built. The operation phase (B6) is characterized by greater environmental impacts compared to the product and construction phases, as well as deconstruction phase due to the use of green materials and technologies.

Family House

Paper is focused on the assessment of two alternatives of family house from environmental performance. Environmental impact categories such as Global warming potential (GWP), Acidification potential (AP) and Eutrophication potential (EP) expressed as CO2eq, SO2eq and PO43−eq using the LCA assessment method are presented. Alternative solutions of building materials are also compared from phase shift of thermal oscillation. Results show that natural building materials are characterized by lower environmental impacts expressed as equivalent emissions of CO2 (6%), SO2 (24%) and PO43− (44%). The wood fiber board can store nearly 24 times more heat than the mineral wool. The wood fiber boards have a phase shift of thermal oscillation of 7–13 h, while other insulation materials only about 3–4 h.

New Challenges

Globalization leads to new challenges. There is a trend of growth of the population. At the same time, production processes are subject to changes. If the new technologies are based on environmental protection, then we can also be considered that the greenhouse gas emissions will be reduced. As energy requirements are rising, it is important to efficient use of natural resources. This, especially, as energy sources differ from one country to another. In this context, dependence on energy imports becomes important. From this point of view, for the countries of the European Union, the article analyzes the evolution of energy efficiency. In recent years, it trying to replace fossil fuels with renewable fuels. Analyzing the share of energy from renewable sources in total electricity allows us to observe the degree of decarbonisation of the European Union economy. The use of energy from renewable sources allows the development of green technologies and contributes to the protection of the environment. Producing of the energy in a region and transporting it to another region creates bridges and contributes to globalization. Thus, in the process of globalization, the role of energy is increasingly important. The article presents a European analysis of gross and net electricity production.

The Impact

Abstract Acidification and Eutrophication are two environmental impacts that have a significant effect on air pollution and human health. The quantitative analysis of these two impacts remains hitherto unknown at the scale of new neighborhoods. The main purpose of this research is to evaluate, analysis and compare the acidification and eutrophication potentials of one neighborhood initially located in Belgium. To perform this comparison, the same neighborhood design is applied to in150 countries, but four parameters are adapted to each country: energy mix, local climate, building materials, and occupants’ mobility. In addition, this research evaluates the induced environmental costs of the neighborhood over 100 years and examines the impact of the photovoltaic panel on these environmental impacts. This research, extended to the scale of several nations, will enable new researchers, and especially policy-makers, to measure the effectiveness of sustainable neighborhoods. Eutrophication and acidification potentials were assessed under different phases (construction, use, renovation, and demolition), with Pleiades ACV software. Among the four local parameters (energy mix, local materials, climate, and transport, the energy mix has the most significant effect on the two studied environmental impacts. The results show that 72 %, and 65% of acidification, and eutrophication potentials are produced during the operational phase of the neighborhood. In the case of sustainable neighborhoods, the acidification potential is 22.1% higher in the 10 top Low incomes countries than the 10 top High-income countries. At the neighborhood scale the main eutrophication potential component is water (34.2%), while, the main source of acidification potential is electricity production (45.1%)

The Impact

Geomicrobiology, the marriage of geology and microbiology, is about the impact of microbes on Earth materials in terrestrial systems and sediments. Many geomicrobiological processes occur over long timescales. Even the slow growth and low activity of microbes, however, have big effects when added up over millennia. After reviewing the basics of bacteria–surface interactions, the chapter moves on to discussing biomineralization, which is the microbially mediated formation of solid minerals from soluble ions. The role of microbes can vary from merely providing passive surfaces for mineral formation, to active control of the entire precipitation process. The formation of carbonate-containing minerals by coccolithophorids and other marine organisms is especially important because of the role of these minerals in the carbon cycle. Iron minerals can be formed by chemolithoautotrophic bacteria, which gain a small amount of energy from iron oxidation. Similarly, manganese-rich minerals are formed during manganese oxidation, although how this reaction benefits microbes is unclear. These minerals and others give geologists and geomicrobiologists clues about early life on Earth. In addition to forming minerals, microbes help to dissolve them, a process called weathering. Microbes contribute to weathering and mineral dissolution through several mechanisms: production of protons (acidity) or hydroxides that dissolve minerals; production of ligands that chelate metals in minerals thereby breaking up the solid phase; and direct reduction of mineral-bound metals to more soluble forms. The chapter ends with some comments about the role of microbes in degrading oil and other fossil fuels.

This chapter discusses the role of energy in economic development, the transformation of energy markets, trade in energy resources themselves, and the geopolitical dynamics that result. The transformation of energy markets and their expansion via trade can help or hinder development, depending on the processes behind them and how stakeholders interact. The availability of renewable, climate-friendly sources of energy, domestically and internationally, means that there is no inherent trade-off between economic growth and the use of fossil fuels. The existence of economic, political, social, and geopolitical adjustment costs means that the expansion of international energy markets to incorporate alternatives to oil and coal is a complex balance of environmental trade-offs with no solutions completely free of negative impact risk. An understanding of the supply of and demand for energy must incorporate the institutional context within which they occur, as well as the social and political dynamics of their setting.

Sustainability Assessments

This article departs from the perspective of Swedish regional transport authorities and focuses on the public procurement of bus transports. Many of these public organizations on the county level have the ambition to contribute to a transition involving the continued marginalization of fossil fuels and improved sustainability performance. However, there are several renewable bus technologies to choose between and it can be difficult to know what alternative (or combination) is preferable. Prior research and the authors’ experiences indicate a need for improved knowledge and supportive methods on how sustainability assessments can support public procurement processes. The purpose of this article is to develop a multi-criteria assessment (MCA) method to support assessments of public bus technologies’ sustainability. The method, which was established in an iterative and participatory process, consists of four key areas and 12 indicators. The article introduces the problem context and reviews selected prior research of relevance dealing with green or sustainable public procurement and sustainability assessments. Further on, the process and MCA method are presented and discussed based on advice for effective and efficient sustainability assessments. In the companion article (Part II), the MCA method is applied to assess several bus technologies involving biodiesel, biomethane, diesel, electricity, ethanol and natural gas.
