The lack of defined land uses in most parts of Greece (80%) has led to multiple environmental problems and phenomena of informal (arbitrary) construction with secondary side effects, such as a lack of basic technical and environmental infrastructure, unfair competition among private investors, the strengthening of climate change (increase in the number of urban diffusion) and the decline of natural and cultural resources. The Greek urban policy, over the last 100 years, has not succeeded in limiting these problems and for that reason the new Law 4759/2020 is expected to promote the development of a more efficient spatial planning system reform implemented through the Local Urban Plans (LUPs) and the Special Urban Plans (SUPs) that are funded by the Recovery and Resilience Facility (RRF). These programs will contribute to the preservation of cultural heritage and to the development of productive activities at both local and national levels, especially on the sectors of renewable energy sources, the circular economy, and the construction of “green” materials, digital applications and products etc. LUPs and SUPs are related to the holistic reform of the national urban policy and the relevant planning system that horizontally affects a wide range of policy areas such as: environmental protection and adaptation to climate change (for natural ecosystems and biodiversity; agriculture; forestry; fisheries; water resources; coastal zones), built environment and development, protection of historic sites and buildings, allocation of the public infrastructure, allocation of investments etc. The General Secretariat of Spatial Planning and Urban Environment Ministry of Environment and Energy has the main responsibility for the implementation procedures of all the proposed actions that will start in 2022 and will end in 2026. This paper focuses on the analysis of the current urban policy reform in Greece and the reasons that this reform is considered an immediate necessity in the current Greek urban legislative framework and the expected outcomes of LUPs and SUPs, which are examined in the literature for the first time, contributing to research on the present EU planning systems.
The construction sector is of strategic importance for the European Commission. This is the reason why there is a special interest in the development of this sector which is attempting to transform into a more sustainable one in order to face various challenges. In this context, European Directive 2014/24/EU brings to the foreground of the European institutional framework the term building information modelling (BIM), that it is widely used in many countries across Europe. In Greece, the situation seems to be different, not only because it has not been applied in practice but also because of some special features of the way the construction sector functions. This paper presents the BIM use-level in Greece and the way with which it could be better integrated in the construction sector. Through this review we make a brief assessment of the strategy developed in order for the BIM to be integrated in Greek building procedures. Furthermore, we focus on specific issues, like the extended informal housing phenomenon, and on factors that cannot easily be standardized that create problems in BIM use. Finally, through an initial market analysis we underline the role of academic institutions for integrating BIM across Greece.Such a direction seems to be the continuation of the Horizon 2020 Strategy directions that aimed at the creation of healthy, safe, viable and intelligent infrastructure [1].In this context, European Directive 2014/24/EU [7] brings to the foreground of the European institutional framework the term building information modelling (BIM). The term is mentioned in article No. 22 of the Directive where it is noted that in the framework of signing public works contracts and the invitation to tenders for relative studies, the member states must include the use of specialized electronic modelling tools for building construction information or similar means. Even if BIM is widely used in countries like France, United Kingdom and Germany [8], things in Greece are very different. This paper presents the BIM use level in Greece and the way with which it could be better integrated in the construction sector. The aim of the work is to present an overview of the situation and to make a brief assessment on the proposals developed for the better adoption of the tool in Greece, taking into consideration the European experience (Section 3). Previously (Section 2), a literature review is undertaken where the tool is described along with the advantages of its use. The results that arise (Section 4) permit a review regarding the actions taking place and programmed in the immediate future. Building Information Modelling (BIM) in Promoting Sustainable Development: A Brief Literature ReviewBIM became a popular acronym in the last decade [9], although it emerged as a concept in the late 1970s [10], after years of research in order for the components and repercussions of building product models to be investigated [11]. It is a process that uses computer technology [12,13] to stimulate the performance of a building, during the whole...
Nowadays, due to economic crisis, the number of "abandoned", empty or dilapidated listed or historic buildings of Greek cities and settlements is constantly increasing. In order to protect and enhance the Greek tangible cultural heritage, it is necessary to promote actions that give motives to owners or users of historic buildings to preserve them, by providing tools and financial support in the particularly increased costs of restoration and consolidation works of their necessary continuous maintenance. The program “Preserve” introduced by the Hellenic Ministry of Environment and Energy, and more specifically the General Secretariat of Spatial Planning & Urban Environment, relates to interventions in designated as listed or monuments or buildings within historic sites and traditional settlements and historic buildings. The interventions will include facade cleaning (with gentle water jet to remove air pollutants or anti-graffiti painting for protection against vandalism), works in order to preserve the shell of the buildings so as to avoid it’s partial or total collapse, restoration of facades and restoration of the interior of the buildings. Along with the activation of the Digital Land Bank, the Building Rights Transfer, the Single Digital Map, and the Digital Building Identity etc., it will offer the owners of the listed buildings a holistic solution for the protection and enhancement of the tangible cultural heritage of Greece.
