Flâneuring and observing the city. The self-ethnographic experience in urban planning
Authors: Pamporis V , Micheli A 
Published: November 2021

Abstract
In this article, our intension is to shed light on this thought: the city in all its dimensions, becomes a reception space not only in the base of individual perceptions but also through a “nostalgic” lived dimension for something that may have been irrevocably lost or for something that is desirable. This point of view enables us to approach the city in an emotionally way of seeing, against the irrational, technical and unquestionable manner used by urban specialists. So far, the social and anthropological factor in urban planning has not been the main goal on the projects. Nevertheless, the postmodernity perspective demands new steps forward on urban field thought which are more dialectical and with a strong personal value imprint of the inhabitant’s demand. The study aims to evaluate the (possible) attitudes, representations, conflicts and desires of inhabitants and specialists for specific urban environments (cases) integrating the sense of the imaginary (subjective) perception and the dimensions arising from the reception of architectural structures and forms in the space but also to gain insight of a dipper understanding of the idealistic image of the city entities.
Urban playgrounds as potential green infrastructure: The case of Thessaloniki
Authors: Katsavounidou Garyfallia 
Published: November 2021

Abstract
In Greek cities and towns, playgrounds, which represent a significant portion of open public space available in high density compact urban areas, fail to positively impact the sustainability of the urban environment, as they are made of artificial materials and generally lacking in natural elements. Designed around safety from accidents, a typical urban playground is equipped with prefabricated play structures, surrounded by an extensive area of rubber protective floor providing a surface safe from falls etc. This water-sealed surface does not absorb rainwater and has a very hazardous behaviour in hot temperature climates, such as Greece has. This “toxic turf,” a product of recycled elastic tires, contains chemicals suspect for cancer. In addition, trees and vegetation are usually insufficient or absent, thus worsening the overheating due to lack of shade. Although this model continues to prevail in Greece, around the world there is a significant shift towards natural playgrounds – play spaces that are designed to incorporate trees, shrubs, dirt, sand, grass, and play elements that are not industrially manufactured but constructed in situ, using stone, wood, reed, and other natural materials. From a pedagogical point of view, a stereotypical playground offers a rather dull and uninteresting environment for children to play, compared to the rich experience of a natural playground. Therefore, if designed as green infrastructure, playgrounds can considerably contribute to urban climate adaptation and a cooler microclimate and at the same time provide opportunities for urban children to come to contact with nature and benefit from free play. The scope of the paper is to present the multiple environmental benefits of natural playgrounds and to calculate the potential positive effects by the transformation of playgrounds into green spaces in a compact urban area. The field study examines the existing playgrounds in the municipality of Thessaloniki and their potential to become part of the city’s green infrastructure.
Climate change adaptation through spatial planning: the case study of the region of Western Macedonia
Authors: Lazoglou M , Serraos K 
Published: November 2021

Abstract
In this paper the compatibility and complementarity between the Regional Adaptation Action Plans (RAAPs) and other regional-scaled plans, such as the Regional Spatial Planning Frameworks (RSPFs), are examined, using as a case study the Region of Western Macedonia. The compatibility and complementarity of objectives, measures and tools between the RAAP and the RSPF of Western Macedonia are assessed. The analysis of the RAAP and the RSPF of Western Macedonia revealed the interconnection between spatial planning policies and adaptation to climate change policies. However, severe doubts are raised about the usability of the revised RSPF of Western Macedonia since it does not assess the crucial new conditions and priorities related to the region’s future development, including the de-lignification and the Just Transition initiatives.
Basic principles of the TEVY index for the quantification of temperature variability within a year
Authors: Kalyvas Theodoros , Manika Stella , Zervas Efthimios 
Published: November 2021

Abstract
In the context of climate change, there is a need for the determination of appropriate indexes for the quantification of temperature variability. A new index (TEVY index) is proposed in this work. This index uses the deviation of the observed temperature values from those estimated from a Fourier harmonic analysis. For this purpose, a nearly 50-year time series data from 4 stations in Greece, with very different climatic conditions, are used. One station is located in the colder northern region of Greece, another one is in the warmest southern part, while the 2 other stations are representative of continental and Mediterranean climatic features. A Fourier harmonic analysis is carried out to obtain the Fourier series which simulates the observed data time series. Fourier harmonic analysis, which is relied on the Fourier transform, is a well-established method for time series analysis, particularly for modelling periodic data. Using this procedure, an index of temperature variability is proposed, as the sum of the divergence of the above-mentioned Fourier series from the observed data. The index results are analysed as a function of the different climatic features of each station.
Development and application of energy decoupling index as Cartesian Vector: evidence from world-wide regional data
Authors: Brilakis Demetrios S , Tsesmelis Demetrios E , Zervas Efthimios 
Published: November 2021

Abstract
Economic growth and energy consumed is critical for sustainable global development. In this paper, an extended Vector version of the commonly used Decoupling Index De of energy elasticity to Gross Domestic Product (GDP) and Decoupling Ratio of Energy Intensity of GDP are used to investigate decoupling phenomenon for the period 1990 to 2014 in the main regions of the World. Using Vector properties, this study overcomes some well-known deficiencies of Energy to Growth elasticity Decoupling Index and suggests the Decoupling Angle as a suitable indicator when describing decoupling. The relationships with aggregate and per capita indicators are also examined. A general finding was that in emerging economies, even when moving to “disconnected” states of decoupling, reduced energy rates were paired with reduced growth rates and accelerated growth rates with increased energy consumption rates. This statement raises questions over long-term decoupling of energy consumption from economic growth.
Factors affecting fuelwood production and consumption in Greece
Authors: Diafas I , Arabatzis G 
Published: November 2021

Abstract
Wood, one of the most important renewable energy sources (RES), has been used as a fuel since ancient times. Wood was the first material to be used for energy production. Gradually its use as a fuel dwindled as other sources gained popularity. However, following the oil crises of the 1970s, various countries switched to RES and in particular to wood as a primary heat source. The current paper attempts to highlight the factors that affect fuelwood production and consumption in Greece in recent decades and to propose a number of policy measures. More specifically, fuelwood production in Greece over the last decades is constantly declining mainly due to overgrazing, forest fires, urban sprawl, poor management and inadequate transport infrastructures; all these factors considerably impact the country’s forest productive capacity. Several decades ago, fuelwood was in great demand in Greece. Gradually, however, it lost its popularity to other heating fuels and was only used in rural residences or in a small number of urban homes. The last decade, however, owing to the deep economic crisis afflicting the country, there has been a marked increase in the demand for fuelwood mainly by low-income households.
Analytical study on the effect of extreme seismic strains on the transverse buckling of ultra-reinforced seismic walls and their environmental design
Authors: Chrysanidis Theodoros , Panoskaltsis Vassilis 
Published: November 2021

Abstract
In the context of the present work, the influence of the degree of tension on the phenomenon of transverse instability of reinforced concrete seismic walls is examined. Useful conclusions are drawn regarding the influence of the degree of elongation on the phenomenon of transverse buckling. These conclusions are substantiated both experimentally and analytically, as the results of the experiments are compared with the corresponding results of the analytical investigation. Moreover, some thoughts on a more environmental design of R/C seismic walls are stated. The present investigation is both experimental and analytical and consists of 4 test specimens. These specimens simulate the extreme boundary edges of structural walls. All columns simulate only the extreme reinforced areas of the walls, in order to study the basic mechanism of the phenomenon. The detailing of the specimens consists of 6 rebars with a diameter of 12 mm for each bar. The geometric dimensions are the same for all specimens. What differentiates the specimens from each other is the degree of tension they have sustained. More specifically, the tensile degrees used are 10‰, 20‰, 30‰ and 50‰. The loading stages of each specimen for all specimens are as follows: (a) Uniaxial central tensile loading on each test specimen apart from the specimen sustained 0‰ degree of tension; (b) Uniaxial central compression loading on each specimen till its failure due to buckling or due to an excess of its cross-section compressive strength. The present study focuses on the tensile loading stage only. Extreme tensile strengths are also used, e.g., 30‰ and 50‰, in order to take into account, the cases of extreme seismic excitations. The experimental study is followed by the numerical investigation of these 4 specimens using appropriate statistical software and finite elements.

Authors: Nikolaou G I , Meresi A K 
Published: November 2021

Abstract
The present work focuses to the efficient use of daylight in school buildings, which has been proved that is able to create a pleasant atmosphere, increase student productivity and comfort and also contribute to energy savings if combined with a daylight-responsive control system. The architectural-bioclimatic design contributes to the creation of technical solutions that provide daylight in existing classrooms, taking into account the climatic conditions and the needs of users. The purpose is to investigate the most prevalent shading and light redirection systems in a typical Greek classroom, in every climatic zone of Greece and come up with the most efficient ones. Research takes into consideration the distribution of daylight on working level and the total heating energy consumption throughout the school year, ensuring conditions of visual comfort. After evaluating and comparing the data, the outcome of this research demonstrates the most efficient shading system for each climatic zone, in order to achieve visual comfort and energy savings.

Abstract
The use of municipal football fields by a large number of citizens and amateur athletes on a daily basis during evenings is a popular activity. Usually, the aiming of the pitch lighting, without taking into account the dense urban environment in the surroundings, causes light pollution. Obtrusive lighting in most cases is the rule and not the exception. This situation could be justified in football fields of the professional football leagues so as to address the needs of television broadcasts of the matches for two days per month per field. However, in amateur activities due to the lack of rules and the initial incorrect lighting design, the problem of light pollution is deteriorated. The scope of this research is to identify the main issue and the repercussions of obtrusive lighting in the urban fabric, propose a quick method to quantify light pollution in sport fields using IDA-Criteria for Community-Friendly Outdoor Sports Lighting guidelines and to further set some parameters for a method using more calculating surfaces.
An overview of environmental impacts of lighting products at the end of life stage through life cycle impact assessment
Authors: Grigoropoulos C J , Doulos L T , Zerefos S C , Tsangrassoulis A 
Published: November 2021

Abstract
Life Cycle Impact Assessment (LCIA) of lighting products is a methodology that analyses and evaluates environmental impacts throughout their total life cycle, from the extraction and processing of raw materials, design, construction, transportation, distribution, use, recycling and re-use of materials, and last their final disposal. According to the results of a large number of LCIAs, lighting products have a substantial environmental impact in multiple areas, as for example in primary energy, toxicological effects, the effect on global warming, the level of environmental acidification, etc. All of those impacts could result in more efficient products by enhancing the product design process (using Ecodesign). At the initial design stage of lighting products, the manufacturer should also take into consideration circular economy aspects at the End of Life stage (EoL) such as repair, reuse, remanufacturing, retrofitting, recycling, and upcycling and not only the energy savings from the use stage or the selection of raw materials. The scope of this paper is to collect and present an overview of all environmental impacts of LCIA analyses focusing at EoL stage of lighting products. Those impacts could be used as data input into a future model that determines which lighting products are more environmentally friendly.

Published: November 2021

Abstract
The use of glass fiber reinforced plastics is steadily increasing in the aerospace industry for aircraft interiors. However, the glass fiber reinforced plastics, although provide a robust solution they have many issues concerning their environmental friendliness. An alternative environmentally friendly solution for aircraft interiors is the use of bio-composites. Bio-composites used in this kind of applications are made of natural fibers as reinforcement and the use of bio-resins as matrix material. In the present study a life-cycle assessment approach is applied to selected bio-composites scenario and the comparison were made against the currently used glass fiber reinforced plastics. Results show the use of flax fiber reinforced materials seems to have lower environmental impact.
Experimental study of the mechanical properties of burnt clay bricks incorporated with plastic and steel waste materials
Authors: Ebadi-Jamkhaneh M , Ahmadi M , Kontoni D-P N 
Published: November 2021

Abstract
Traditional masonry bricks are made of clay burnt under high temperatures, resulting in high energy consumption, environmental contaminations and decreased natural raw materials. In order to limit nature risks, inorganic materials have been used to make brick. Four types of materials, including fine and coarse plastic, cast iron, and iron swarf, have been used to make bricks. A total number of 64 specimens were made and tested. The tests results were presented in the form of compressive strength, rupture module, water absorption percentage, and initial water absorption ratio. The result showed that using cast iron powder caused the maximum compressive strength amongst all the samples, and was 46% larger than for the reference bricks. On the other hand, the maximum initial water absorption occurred within the first three hours, while the maximum rate was associated to samples with higher coarse plastic contents.
Proposals for an environmental and social just transition for the post-lignite era in Western Macedonia, Greece
Authors: Zervas Efthimios , Vatikiotis Leonidas , Gareiou Zoe 
Published: November 2021

Abstract
This text formulates a set of coherent and realistic proposals for the after delignification period in Western Macedonia. The aim of these proposals is to avoid the economic decline and poverty of the Region. The first part, based on the literature and the best available practices, the proposals for the necessary environmental restoration of mine lands. Concerning the economic rehabilitation of the Region, a mix of actions referring to the whole production chain: from the primary to the tertiary sector of the economy, is proposed. The action that is expected to enhance the production potential of this region is the creation of branded products, under a single brand name, which will voluntarily bring together, in the context of synergies, the agri-food and manufacturing activities. Overall, it is estimated that the deadline set for de-lignification in 2023, is too early to start all those activities that will allow the economic transition of the Region, and to exclude the possibility of a massive wave of migration. For this reason, the extension of de-lignification, for a period of time within the European objectives to achieve the target of climate neutrality in 2050, are proposed.

Abstract
Adaptation to climate change as well as the increasing demand for a new approach in post fire socioecological resilience and Nature-Based Solutions (NBS) in forest management requires a different way of thinking of forest roads planning, in terms of Social-Ecological Systems (SES) Framework. Social-ecological systems are complex, adaptive and emphasize that social and ecological systems are linked through feedback mechanisms, and that both display resilience and complexity. In this frame, it is important to clarify the considerable dynamic elements for the future development of forest roads planning and management that promote natural, socio-economic, and cultural well-being. The main objective of this paper is to identify important new challenges concerning the forest roads planning and management and to propose a conceptual paradigm towards SES in a continuing changing climate, social needs and environmental conditions. Hence, a newly developed concept under the prism of SES forest roads planning, is presented. Eight key performance areas to ensure the forest operations as SES include: (i) nature’s services; (ii) ergonomics; (iii) environmental economics; (iv) quality optimization of products and production based on NBS; (v) the use as evacuation routes; (vi) access to renewable energy sources; (vii) people and society; and (viii) resilience. The conceptual frame of SES provides a close to nature perspective which addresses the ongoing and foreseeable challenges that the global forest ecosystems face, based on harmonized forest operations performance across economic, environmental and social sustainability. In this new concept, we demonstrate how these eight interconnected principles interact to each other and are related to forest operations achieving Nature Based Solutions in forest management and climate change mitigation.
Project risk management adaptation of infrastructures in the Greek context
Authors: Demertzis G , Vatalis K I 
Published: November 2021

Abstract
Last years in Greece there has been an increase in the number of “Small and Medium Enterprises, SMEs” active in the construction of infrastructures and specifically in the telecommunications sector. The research methodology was done with an appropriate questionnaire which is addressed mainly to construction companies. Large companies, for both operational and financial reasons, prefer to outsource projects and services related to their network infrastructure to third companies rather than using their own resources. SMEs undertake to implement many of these services. They are more flexible in terms of operation but also adapt faster to the requirements of the projects they undertake. However, unlike large companies, they lack in procedures and have limited administrative resources. This makes them more vulnerable to the risks presented in the various phases of the projects they undertake. Risk Management, as a process, includes the identification of risks, the prediction of the probability of occurrence and its consequences and finally proposes solutions to treat them. The research investigates the current situation regarding risk management by Greek SMEs. The results showed up that although the use of relevant risk management procedures is limited, the participants believe to the usefulness of the process according to international standards for the projects that SMEs implement.
The contribution of European structural and investment funds to the strategic planning of sustainable development in the national forest parks of Greece

Published: November 2021

Abstract
Sustainable development represents a crucial environmental policy framework in order to provide multiple benefits for climate, biodiversity and people. The National Forest Parks (NFP) represent protected areas with important forest diversity that play a critical role, both in reversing biodiversity loss and contributing to socio-economic development. The European Structural and Investment Funds (ESIF) pursue the preservation and improvement of the environment in the context of sustainable development. To date in Greece, 16 operational projects have been approved through two ESIFs and concern six NFPs which are supervised by Management Bodies. Critical Assessment of the projects and SWOT analysis for the six Management Bodies has also been implemented. These results highlight the existence of common sustainability goals, which focus on the protection of Natura 2000 sites and on preserving biodiversity, to financial support the NFPs with vehicles and IT equipment, rather than promote sustainability.
