Cultural and natural heritage as a driver of sustainable landscape development
Authors: Šćekić J , Nikolić M , Vaništa Lazarević E , Marić J 
Published: December 2022

Abstract
The Roman Limes - a former natural border of the Roman Empire has been recognized as a cultural landscape with exceptional universal values of international importance by UNESCO. In the Republic of Serbia, the Roman Limes encompasses the Danube river valley. Within this part of the Roman Limes, the Djerdap segment, which includes sites of different historical periods, stands out. However, most of the sites are underwater due to the construction of the Hydroelectric Power Plant. Physical inaccessibility to cultural heritage has led to insufficient presentation and promotion, but also a lack of information about its existence. Therefore, the main goals of this paper are to spread knowledge about the existence of the cultural and natural heritage of the Djerdap segment, as well as to identify the potential for their integration into contemporaneity. The results are presented through an urban-architectural project that is the sublimation of formed critical attitudes about the cultural heritage treatments. The expected results of the research include raising awareness of the importance of the cultural and natural heritage of the Djerdap segment through the promotion of cultural routes, as well as forming a potential model for their use in the process of establishing sustainable landscape development.
THE GREEN LINE | A biodiversity corridor along the past and present Athens railway network
Authors: Kogia N , Papafotiou M 
Published: December 2022

Abstract
The Green Line concerns the study of the introduction of an urban green route in proximity to the railway network of TRAINOSE in the greater area of Athens, Greece. The active and inactive railway network that runs through Athens has posed a challenge to good management, due to the empty spaces and derelict facilities it leaves behind as well as the urban fragmentation it causes. At the same time, Athens, in the midst of the global climate crisis, is in need of a long overdue introduction of urban green, in order to enhance the city’s resilience to extreme weather conditions and threats to biodiversity, especially to the urban and peri-urban fauna. The main motivation of all interventions is the introduction, mobility and enhancement of urban biodiversity. The means to achieve this is both the selection of ecologically valuable plant species able to attract and host important pollinator species and other urban fauna, and their interaction with humans. This interaction is examined in separate cases, depending on the urban and social conditions of each location, and incorporates urban farming (communal gardens, orchards, meeting and education points), urban beekeeping and pollinator care (urban beehives, bee and butterfly beds, bee hotels). These interventions are found along and in the vicinity of the railway network of TRAINOSE, which is divided into typologies and takes the form of individual design case studies. In its current state, this area bisects the city, creates problem areas and runs through densely populated areas with low incomes and a significantly low amount of green spaces, while, the conversions the railway network has undergone in recent decades leave behind areas ready to receive new uses. Most importantly, it can create a functional and practical green route that starts, passes through and ends at key points in the city.
Investigation of the thermal environment in schoolyards under Mediterranean conditions. Contribution to bioclimatic conditions improvement with the application of mild interventions – The case study of a school within the urban environment

Published: December 2022

Abstract
This study aimed to examine the thermal environment in schoolyards under Mediterranean conditions, and the impact of two interventions on the amelioration on the bioclimatic conditions.
The investigation was performed for three schools in Athens, Greece, through microclimatic simulations by ENVI-met, for a typical day in June, and was evaluated based on the air and surface temperature values. The bioclimatic index Physiological Equivalent Temperature (PET) was applied to evaluate the thermal comfort conditions.
By that, the school under the most adverse thermal conditions was selected for the application of two interventions, which increased the greenery by 25% (Proposal 1) and 50% (Proposal 2). The surface coating material “safety floor slabs”, was selected to replace the others in both proposals.
Through microclimatic simulations, the following results were obtained: “Proposal 1” caused a 2.3°C reduction in surface temperature, and a 4% reduction in PET values. ‘Proposal 2’ caused an 8.1°C reduction in surface temperature, and an 11% reduction in PET values. The cooling effect of ‘Proposal 2’ was double compared to ‘Proposal 1’, achieving a maximum air temperature reduction by up to 0.8°C. The cooling effect produced was limited to the areas affected by tree shade, leaving the unshaded areas almost unaffected.
Energy upgrading of buildings in Greece with eco-materials: An investigation of public awareness
Authors: Antoniou F , Demertzidou F , Mentzelou P , Konstantinidis D 
Published: December 2022

Abstract
The environmental impact of the construction sector is significant making it necessary to adopt sustainable solutions for energy upgrades of buildings. Furthermore, the use of advanced eco-materials to improve the energy efficiency of buildings has been shown to provide better energy conserving results than conventional upgrading materials, contributing directly to the improvement of the comfort level of building occupants. This study investigates the public view in Greece regarding energy upgrades of buildings using eco-materials. A mixed methods research approach was employed based on a questionnaire survey investigating the public’s knowledge of the need, the benefits of using eco-materials and the motivation required to renovate the buildings they live and work in to a higher energy efficient standard. Although technologies in advanced eco-materials have increased, the survey showed that, regardless of the existence of government subsidies, the general public in Greece is unaware of the importance of and benefits from upgrading their buildings with eco-materials. As a result, there is an urgent need to embark on more rigorous environmental awareness campaigns to support local authorities in implementing sustainability policies, like the use of eco-materials for the energy efficiency improvement of buildings, to create sustainable and healthy cities.
The impact of lighting trespass on nearby buildings and their inhabitants which derives from municipal stadiums. Early results from a post occupancy evaluation survey
Authors: Ntarara E , Syngkiridi K , Androvitsaneas V P , Doulos L T 
Published: December 2022

Abstract
Outdoor lighting has a more significant environmental influence on flora and fauna than humans mainly because of the shortest time period that they may be spending outdoors. Yet, light trespass has an equally important influence on people since it may affect the living conditions in their everyday life, and consequently, their prosperity. The present study investigates houses with facades in front of municipal stadiums with no audience and affected by their lighting. The prevailing visual atmosphere caused by the lighting levels and its improper direction is definitely intrusive separating the indoor and outdoor environment. This anthropocentric research, conducted via the Post-Occupancy Evaluation (POE) methodology, aims to detect the visual and psychological effects and consequences of the visual surrounding caused by light pollution because of outdoor night lighting in an urban environment.
Current research trends into the effect of climate change on civil engineering infrastructures: A bibliometric review
Authors: Kalogeraki M , Antoniou F 
Published: December 2022

Abstract
Climate change and the construction industry are inextricably linked. On the one hand, the construction industry is responsible for the highest level of carbon emissions by sector, but, on the other hand, it is considered as the most vulnerable to extreme weather conditions. In this paper, a bibliometric review is carried out for shedding light on the manner with which climate change affects the construction industry and the existing and future infrastructures. Using VOSviewer and the Scopus database, relevant literature is retrieved and analyzed using keyword searches including ‘construction’, ‘infrastructure’ and ‘climate change impact.’ The bibliometric analysis determined how researchers have investigated different climate change factors affecting each distinct construction sector and infrastructure type. The analysis focused on publication year, country-institute, journal, author, and research themes. The detected research themes provide future researchers with potential research directions. A gap in the research regarding the investigation into the climate change effects on transportation infrastructure was determined. Therefore, a content analysis of the relevant papers under the theme ‘transportation infrastructures’ is conveyed. Ultimately, the main research trends and potential research directions for the protection of civil engineering infrastructures against climate change effects are discussed aiming to provide guidance to future research.
An Examination of use of Alternative Reference Sources in Colour Rendering of Environmental Lighting Applications
Authors: Dimitrakis A , Madias E-N , Kotsenos A 
Published: December 2022

Abstract
Environmental lighting applications include smart technologies with energy efficiency, zero toxic elements production, decreased number of luminaires, longer life span, etc. While the research is focused on energy performance and lighting requirements there must be attention for the users’ wellbeing even if the energy consumption is raised. One important aspect for the wellbeing is colour rendering, which is defined as the “effect of an illuminant on the colour appearance of objects by conscious or subconscious comparison with their colour appearance under a reference illuminant”. Reference is the foundation of communication, but no possible reference is inherently superior. The use of Planckian radiation, daylight, or a combination of the two has been established as a reference source because people are familiar with those two non-artificial light sources. Special lighting applications, like tunable light, are based on special specifications and the establishment of alternative design reference sources according to these specifications is a possibility for a better colour rendition. In the present study, different sources were designed with hue-specific chroma changes, and the results of colour rendition were compared with the relative results of standard reference sources. The exported results are reported, and proposals are made for the use of the results.
Design and Development of a Sustainable Environmentally Friendly and Human Centric Luminaire
Authors: Madias E-N , Patrikios E , Grigoropoulos C , Doulos L 
Published: December 2022

Abstract
Apart from the visual effects, light can also affect the human non-visual system, which includes a wide range of functions such as hormone secretion, alertness, mood etc. The non-image forming effects occur because light affects melanopsin, a photosensitive protein present in the receptive domain of retinal ganglion cells. These cells are responsible for generating nerve impulses that regulate the secretion of two hormones, cortisol and melatonin. Low-wavelength light at 460-480 nm inhibits melatonin secretion and activates brain activity. Aim of this paper is to create a sustainable and human centric luminaire suitable for office installations that will regulate the biological rhythm of the occupants and has the minimum environmental impact. The luminaire’s light source emits variable spectrum, with a collated colour temperature varying between 2700K and 6500K. For a 500K step of colour temperature values, the appropriate human centric lighting metrics are calculated: Equivalent Melanopic Lux, Melanopic Daylight Equivalent Illuminance, Circadian Stimulus. The development of the human centric luminaire considers not only the metrics of human centric lighting but energy efficiency and visual comfort as well. Conclusively, the proposed luminaire can provide a holistic approach to lighting design so as to integrate both visual and non-visual effects and produce sustainable and environmentally friendly lighting.

Authors: Pérez Luque Gabriel , Coma Arpon Julià , Reyes Rogget Marcelo , Marias Gonzalez Gerard 
Published: December 2022

Abstract
Among the multiple Nature-based solutions (NBS) that can be applied at city scale, those that make it possible the integration of vegetation and nature on the building’s envelopes, such as green roofs, green walls and green facades, stand out for their ability to re-fill those scarce surfaces of opportunity in the dense built environment. The main objective of the “Verd de proximitat BCN” project is to design a “Monitoring and evaluation plan to assess the impact of green roofs and façades in the city of Barcelona”, which must be inclusive and participatory, economically viable and sustainable over time. To this end, 4 ongoing real projects are being retrospectively monitored in order to evaluate their impact. With the obtained results, a proposal for the future “Monitoring and evaluation plan for the operation and impact of green roofs and façades” will be drafted to be applied in future projects during the design phase of these solutions (prospective monitoring).

Authors: Galanaki T , Giannarou S , Zervas E 
Published: December 2022

Abstract
Energy consumption in school buildings and improving their energy efficiency is an important research issue. This study aims to investigate the energy behaviour of school buildings in Greece, based on their date of construction and technical characteristics, before and after the implementation of various bioclimatic intervention scenarios on them and the subsequent estimation of their cost according to their typology. The method followed is the research and collection of data on the evolution of school buildings over time and their classification into three categories, to determine the most representative in regards to their time period and their technical characteristics. Based on this standardization, their energy situation is assessed with the program of TEE-KENAK and the implementation of the Technical Instructions TOTEE / 2017. Then, scenarios regarding bioclimatic passive interventions in the shell of the buildings and in their electromechanical installation are applied and their energy efficiency is investigated, which improves significantly, especially in older buildings, with a respective reduction in their energy consumption. Finally, the cost of these interventions is calculated, depending on the category of the building and the type of intervention.
Development of transport in Albania and opportunities for a sustainable transport
Authors: Cacaj P 
Published: December 2022

Abstract
Transport in the Republic of Albania, with all efforts for its development, has not yet reached the contemporary levels and standards. While the transport of passengers and goods, carried out by road transport, has undergone a great development, the same can’t be said for rail transport.
Rail transport is a great untapped potential, low cost, with low levels of pollution and no traffic jams. Through this paper we’ll try to provide an analyse of the total demand for freight and passenger transport as well as the possibilities of developing rail transport by comparing it with road transport.
The methodology of the study is based on the classical model of transport. Graphs of traffic flows as well as analysis of official statistical data will be the basis for drawing conclusions.
The need for the development of rail freight and passenger transport is urgent, as the capacities of national road axes are reaching maximum traffic values.
The connections of Rail transport with the countries of the region would affect the reduction of means of transport and would meet the needs of different passengers. Based on the results, we will give some suggestions regarding the development of rail transport.
Evaluating transport sustainability in metropolitan Athens through a cable car proposal as a partial alternative to the announced metro Line 4.
Authors: Papadopoulou Iris , Tzanetatos Dionisis 
Published: December 2022

Abstract
Transport sector bears a significant share of responsibility for today’s society environmental issues. In this context, transport ought to include sustainable design principles in the early stages of development of each project. The present work examines an alternative proposal for Metropolitan Athens urban transport, introducing an innovative solution that has recently emerged, urban cable cars. Through literature study and the review of other cities’ best practices, cable cars’ technical characteristics as well as favourable and limiting factors are analysed. A new cable car line is proposed as a partial alternative to line 4 of the Athens metro, which construction has been announced to begin soon. The area of interest covers Zografou and Kaisariani Municipalities, located just a throw stone away from the center of Athens. Comparison factors include capacity, travel time, accessibility, safety, construction time and cost, operating and maintenance costs, environmental impacts, social acceptance and travel quality. Results indicate that cable cars provide sufficient capacity for the specific area offering many environmental advantages and also better coverage, lower cost (both construction and maintenance), lower energy consumption and better travel quality. On the other hand, Athens metro line 4 is evaluated as over-designed according to the expected ridership. As the latest developments in technology show, cable cars are sustainable means of transport with great potential within the urban fabric, under certain circumstances. The contribution of this work relies on revealing alternative solutions to cities’ transit problems, which in terms of environmental design can be resolved without the need to invest in large-scale projects such as metros.

Published: December 2022

Abstract
Auto-regressive integrated moving average (ARIMA) assessment of traffic noise was conducted on different routes in Port Harcourt, Nigerian metropolis. This was achieved by measuring the traffic noise on the various routes of asphalt flexible and concrete rigid pavement structures with a meter for sound measurement with regards to the volume of traffic, vehicle movement rate, and location away from the midpoint of the highway. The average peak noise of traffic was obtained at selected distances of 5m, 10m, and 15m from the middle of the highway, for locations 1, 2, 3 and their mean average case 4 (Trunk A flexible pavement), for location 5 (Trunk C flexible pavement), and for location 6 (Trunk C rigid pavement). The results of the investigation show that the values of traffic noise at locations 1 to 3 and their mean average case 4 had the same range of high noise intensity as Trunk A flexible pavement and classified as heavy-traveled roads; while conversely, location 5 (Trunk C) had the same range of lower noise intensity, which was classified as light-traveled road. For Trunk C, the noise generated in a flexible pavement was less than that from a rigid pavement. Generally, the R2 values of the ARIMA models showed very good performance along selected travel routes. For case-specific distances, the ARIMA models performed very efficiently and had very high R2 values.

Published: December 2022

Abstract
The COVID-19 pandemic had some positive results regarding the established policy of the European Union (EU) of promoting active mobility, such as the creation of temporary bicycle lanes and paths, to facilitate mobility in the era of social distancing. Such a bicycle lane was constructed in the city of Thessaloniki, Greece, on Konstantinos Karamanlis Avenue. In the summer of 2020, during the COVID-19 pandemic, a bicycle lane was constructed on Konstantinos Karamanlis Avenue. In the present paper, a questionnaire survey is presented regarding the functionality, effectiveness, safety, and environmental impact of this specific bicycle lane. In total, 228 people participated in the survey. They were able to evaluate the different problems encountered on the bicycle lane and the behavior of the other road users and to make judgments and suggestions for its improvement. Important conclusions emerge from the collected data, such as that the citizens believe that there are significant problems with the safety of the bicycle lane and less important problems with its operation. Finally, it seems that there is a great desire to strengthen active mobility and especially cycling in the city of Thessaloniki, given that the infrastructure will provide the appropriate safety.
A review on best practices using hydrogen fuel-cell electric vehicles in public transport

Published: December 2022

Abstract
Road transportation sector is responsible for 21.8% of EU’s CO2eq emissions forcing the shift to a de-carbonised mobility scheme, whilst maintaining competitiveness and satisfying the increasing demand mobility needs. Thus, the development of electric vehicles (EVs) and the investigation of alternative fuels by the research community have emerged. Hydrogen is considered a good substitute fuel for the road transport sector if it is produced from renewable energy sources. Several cities have already started to replace a percentage of their conventional public transport fleet with fuel-cell electric vehicles (FCEV). This paper provides a detailed presentation of several best practices applied in small-medium scale European cities and regions. Best practices are investigated from a city-centred point of view to provide a clearer understanding of the hydrogen initiatives performed in the specific areas. The selected scenarios have demonstrated and implemented different state-of-the-art hydrogen applications in the hydrogen mobility supply chain, which could be potentially tested in other regions with similar geographical, economical and transport activities. Finally, the outcomes of this review study identify different challenges, barriers and opportunities of hydrogen mobility applications which other cities should take into consideration before investing in this technology.
