Urban Space and strategy for sustainable development in the
Mediterranean
The Mediterranean region is an area of vital strategic importance to
Europe , which both the EU Council and the European Commission have identified as a key priority for the EU. The populations living along the coasts of the
Mediterranean
Basin are united not only by ancient historical and cultural ties, but also by the fact that they belong to the same ecosystem or eco-region. This historical and ecological unity is paralleled by many differences, which go over and above the traditional North-South divide. But regardless of the different backgrounds of the countries in the region, the future of the Mediterranean basin depends on its people’ s ability to conceive a collective management, manifest interdependencies linking them, whether geographical (the sea), political, economic (trade), social (migratory flows) or cultural. Sustainable development can restore the sense of a common future for this region and can provide the opportunity to ensure the convergence of strategies led by various stakeholders. The future of the Mediterranean basin will depend largely on its urban space which has always been important in the
Mediterranean but which will count 380 million inhabitants soon or 80% of the population of the whole of the countries. With nearly 80% of urban population about 2030, the future of the
Mediterranean will depend mainly on cities and the ways of life of the urban populations. The stakes are a little different in the countries of the northern coast, where a process of peri-urbanisation prevails in spite the moderate modes of demographic growth. In North as in the South, control of the urban development, improvement of the framework of life in the cities, the promotion of ways of life minus gaspilleurs and less pollutants, constitute major objectives to inflect the heavy tendencies of the urban growth.
« ….The future will undoubtedly depend on the policies followed locally, on the scale of the agglomeration, city, and district. There will need a strategic city planning, participation of the populations, taking into account all dimensions, economic, environmental and cultural of the urban fact. However, vis-à-vis with the immense challenges of a sustainable development, cities, alone, will not be able to do everything. A change of scenario supposes that the efforts are committed at the same time by the cities, provinces or areas and States, with the euro-Mediterranean support, to create necessary synergies and to work in the same direction. The future will also depend on the followed policies on the level of the countries, policies of regional planning at the national and regional level in favor of the medium-sized cities and the cities of the interior. In addition, at the
Mediterranean and the Euro-Mediterranean level and, without an efficient regional co-operation, the networks of cities and the projects of decentralized co-operation will continue to have problems to be operational in the long term. Decentralized co-operation, alone, cannot face the stakes either. The area would profit from a programme of euro-Mediterranean co-operation which would mobilize the States as well as the European support in favor of the medium-sized cities and the urban zones in difficulty, to work effectively for a more sustainable urban development in the
Mediterranean .... " (1)
Traditional Mediterranean urban space quality and current conditions
The Mediterranean region has traditionally developed exceptional expertise in architecture and urban design, showing great ingenuity in adapting to the climate ( mild, sunny winters, very high temperature peaks in summer ).The choice of layouts, openings, materials, patios and fountains and narrow shady streets have produced an urban environment and architectural heritage perfectly adapted to the climate. But more recently, urban expansion and changes in lifestyles have been contributing to the emergence of urban developments and architectures that, by their very design, are too disconnected from the climate, leading to an over-consumption of energy for heating and cooling (ventilation and air-conditioning). Glass-encased skyscrapers are increasing in the Mediterranean cities despite their being totally unsuited to summer heat. Yet a few simple building rules, satisfying new demands for comfort and adapted to the climate, would enable substantial cumulative savings for the whole life cycle of the buildings. To get back in touch with its climate, Mediterranean architecture could reintroduce a few simple building principles that it has jettisoned rather too rapidly. The principle of sustainable architecture in the region can be mainly the principle of bioclimatic architecture : to meet new demands for comfort and health for the occupants while reducing, even avoiding, energy expenditure on active heating, ventilation and cooling technologies. Architecture in the region could thus exploit several parameters, either using the building cell or active technologies ( for heating and cooling ).
The Mediterranean region is particularly concerned by the very large expansion of air-conditioning which is expected to continue with the expected growth in urbanization and possibly global warming. Clear signs of a rapidly growing “air conditioning culture” have started to appear during the last decades. Reasons for this development include increasing thermal loads in buildings due to additional equipment, particularly office equipment, as well as cheaper and more widely available cooling technologies. Cooling has become a standard in cars, offices and commercial buildings which contributes to a demand for a "continuous" thermal comfort that is spreading also to households. This effect is much stronger in Mediterranean countries, where the climate and the rising living standards are creating a real “air conditioning culture”. The situation becomes more severe in urban environments due to the so-called “urban heat island” effect that increases the air temperature and consequently increases the needs for cooling and the smog formation in summer. The explosion of room air conditioners (RAC) sales confirms this trend.
How to re-establish the urban space quality in the
Mediterranean ? The role of sustainable construction.
The Athens SB05MED Conference “Sustainable Construction : action for sustainability in the Mediterranean region”[1], initiated by the SD-MED International Association [2] focused on the necessary coupling of architectural quality with the environmental one in the Mediterranean urban space. This event constituted a synergy of international range aspiring to articulate local, national, regional and international initiatives for the promotion of both the idea and practice of sustainable urban environment and more specifically of “sustainable building” and construction. That is to say the building that beyond its classic architectural virtues, beyond its architectural quality implying social, economic and environmental aspirations, it is characterized by the minimization of its environmental impact, that is, it is mostly characterized by the environmental quality, from the excavation of raw material for its construction, during its proper construction, its operation, its maintenance, even in its demolition, that is during its whole life cycle and furthermore in all spatial scales, that is from the scale of its interior space up to the planet scale. The topics and issues of the SB04MED Conference were prepared by the “SD-MED” Association [2] Scientific Committee being responsible for the organizational and scientific coordination of the Conference. The main plenary session topics were structured around the following axes: 1. The specific conditions (economic, social, environmental, cultural) defining urban sustainability, Sustainable building (SB) and Sustainable Construction (SC) in the Mediterranean region. 2. The policies and strategies, the perspectives and barriers for implementation of SB in the Mediterranean countries. 3.There has been also a closing plenary trying to make a first synthesis of the round tables outcomes and trace conclusions. Furthermore, 14 Parallel workshops have taken place dealing with specific issues, ( for details see SB05MED Proceedings, www.sd-med.org) The major outcomes of the SB05MED event can be, very briefly, classified as follows:
A. Concerning methodologies, policies and standards for sustainable building and sustainable city all experts agreed on the fact that given the cultural, technical and environmental specificities in the Mediterranean linked with energy and water use and the fact that the region is a privileged zone of exchange between North and South, there is a necessity to establish places, instruments and opportunities of technology transfer. Sensible issue for the region has been considered the need of subsidiarity in the application of various levels’ regulations ( local, national, regional-Mediterranean, European and international ). Furthermore, focal point has been the respective role and the complementarity between regulations and market oriented measures. Thus, the problems and constraints that were identified were first of all related to the need of new jobs, responsibilities, professional skills, and the relationships between those different jobs. The follow-Up of change and the need of concepts and of simple tools, easily applicable and adapted to the local cultures have been also identified. The discussion about the Projects cost has led to the following conclusions: on the one hand to the necessary progress of investments since it has been argued that cost increase won’t be acceptable even if the life cycle cost favours that, and on the other hand to the necessity of using and developing innovative financial instruments and tax measures in this field.
B. In the question “Where are we in the Mediterranean concerning building and city projects, systems and operations” a general remark has been revealed, that main constraint for implementation is the inertia of the “old world”. All factors affecting dramatically the environment in the
Mediterranean have been analysed ( e.g. the increasing air-conditioning culture ) and the availability of the scientific and technological knowledge on SB was put in question. It was pinpointed that industry as well as professionals and the public are not aware of the environmental impact of construction materials. The cost and the affordability of sustainable constructions was another main issue in the discussion structured around the necessary integration and dissemination of the life cycle cost concept. The relevant proposals and recommendations were the following :
-establishment of a regional mechanism that will gather data and knowledge and will propose instruments and tools for design and evaluation to actors involved in the construction and provide information to state and local authorities to facilitate regulatory, volunteer, economic, investment and other policy measures.
-Integration of SB design as priority course in architectural schools
-Development of a mechanism of information and awareness raising to cope with the inertia of the “old world” and prepare the conditions for change.
-Research coordination and dissemination of available techniques, focus on research for existing buildings and building stock.
-Multiply demonstration projects and support them financially.
C. In the question “where are we in the
Mediterranean concerning Assessment and evaluation instruments and tools” the current situation has been presented as follows: Many environmental methodologies and methods for evaluating the environmental performance of buildings are being currently developed in the world, according to the local cultures and organisation. Especially for the
Mediterranean we have to distinguish VERDE, a software system for assessing the environmental performance of buildings in. Besides, a project methodology, called "HQE", that is high environmental quality has been developed in France presenting a mostly open character: it integrates a great number of parameters, requires a mode of management of the operations inspired by the international standard ISO 14001, and consists of a project methodology instead of a simple ex-post certification like in the majority of the other existing methods. Thus, it offers an interesting framework for capitalising experience feedbacks, and for seeking common denominators. Furthermore the SD-MED Association is preparing the SD-MED Process tool. The main conclusions, recommendations and proposals of the session have been as follows:
- Assessment tools, either rating or labelling, should be simple and friendly to the user. Nevertheless, it has been argued that reference values and systems (benchmarking) would be preferable.
-Green city tools at different scales (urban planning scale, neighbourhood scale) have to be developed. It was mentioned that there are some experiences in
Europe thus transfer of knowledge in Mediterranean countries should be supported.
- Integration in the tools of economic and social aspects has been proposed, as well as involvement of actors like decision makers, private companies, industrial actors etc.
-Case-studies are useful and related training and education programmes have to be developed. Effective use of such tools presupposes the existence of extensive databases with statistics, data on regulations etc. at national or regional level . The need to “work together” was finally revealed.
D. Concerning financial instruments and mechanisms and specifically realities and perspectives of market development the issues discussed can be summarised in the following points :
-There were contradictory opinions about the use of novel and innovative financial mechanisms in financing energy efficiency in buildings and application of RES in buildings.
-It was claimed that scarce public resources and funds mainly for rehabilitation of public buildings and other infrastructures lead to the need to implement public-private partnership schemes and third part financing.
-It has been pinpointed that provision of energy services has to be combined with the proper energy management in buildings.
-About development of ESCOs in the
Mediterranean , it was stated that the development of ESCOs companies is inhibited by some legislative and market constraints.
-Indirect financial instruments were. Share of cost between the user and the community has been also mentioned, practiced in some cases.
The conclusions and Recommendations drafted by the session were quite important for the implementation of sustainable building in the region:
-Financial tools have to be complementary with other instruments or tools like policy tools, training and qualification measures.
-Subsidies, meaning that over cost is resulting from SB are not adequate, nor sufficient. The need to identify best practices of financial instruments to mobilize funds and involve proactive key-players (investors, contractors, ESCOs etc) has been pinpointed.
-In the
Mediterranean , experience has to be developed from pilot projects implementing third party financing schemes, like it is already the case in , UK etc.
-Efforts and willingness of Mediterranean countries to clarify relevant legal framework have to be supported since key actors are quite ready in the market.
-Furthermore, the need of broad information of the public has been identified including a proposal on information points on SB and financial issues concerning its implementation. Raising public awareness in general and user’s participation has been also identified.
-To attract investors and other key-players we have to be attractive and convince about the profits of SB, about what is good for the user and the community as well, in terms, mainly, of value for money.
-Development of ESCOs has been recommended meaning not only energy but environmental service companies which presupposes an easy quantification of environmental quality .
-Finally, the need to develop Life Cycle Cost Tools has been mentioned to facilitate not only energy but environmental performance contracting.
E. Suggestions to the EC and the SB05Tokyo [3]
A general way of action has been drafted by the main rapporteurs [3] : In order to proceed to the elaboration of more effective macro-regional implementation concerning sustainable built environment, one has to find a solution to the following contradiction: -on the one hand create a common language, which will be necessary to exchange experiences and knowledge, -on the other hand promote specific ways to reach environmental performances according to the geographical, cultural and technical local contexts. -Furthermore, a general policy framework to achieve sustainability of the built environment at a macro-regional level (e.g
Southern Europe or the Mediterranean basin) should first of all include the establishment of a mechanism to elaborate methodological bases needed to explore environmental excellence and diversity in different local conditions. These bases have to respond to specific problems and needs to help local actors to create their own systems.
A strategic proposal for coordinated action has been formed concerning the establishment of a Sustainable Building Observation Network in the
Mediterranean . This is an already expressed in various relevant congresses joint proposal of the main rapporteurs (Kyvelou, Bidou, 2003). This observatory has to keep its independent, non-governmental and coordinating character so as effective participation of all the actors, players and stakeholders be ensured ( international organisations, states, local authorities, construction sector, and mainly NGO’s, civil society). Beyond the above mentioned policies and techniques, enhancing transferability of innovative techniques, tools, methods and mechanisms can play a crucial role for an effective regional implementation concerning “sustainable building” in the Mediterranean region.
A Mediterranean SD-MED process
The idea of a new Mediterranean Sustainable Building process was for the first time initiated by the SD-MED Network through a LIFE –ENV Project ( SB-MED) concerning the enhancement of transferability of know-how on sustainable building from northern countries in the Mediterranean region. The project, mostly based on the French approach HQE was aiming at shaping a specific Mediterranean methodology based on the HQE, with adaptability at a macro-regional level. The SD-MED experts involved in the project [4] agreed on the principle that the above methodology has to be a process based on the triple“Efficiency” ,social, economic and environmental. Given the fact that the HQE method concerns mainly the environmental dimension that is the minimisation of the building environmental impact, the team of experts examine in the existing performance assessment tools how the three above dimensions ( social, economic, environmental ) have been integrated and [ropose a new process ( SD-MED Process) based on the systemic and multi-criterial HQE method but enriched with social and economic factors as well. They also initiated an innovative Sustainable Development Management System.
Conclusions
Sustainable building is not a new technique. It is more a frame of mind, taking into account the consequences of all building-related decisions. In most cases, the techniques or know-how already exists. In the special case of the
Mediterranean and Southern European area, local traditional architecture can provide numerous and very significant examples of environmental quality in building with emphasis to passive solar design and systems. In order to proceed to the elaboration of more effective macro-regional standards concerning sustainable built environment, we have to find a solution to the following contradiction: on the one hand create a common language, which will be necessary to exchange experiences and knowledge, and on the other hand promote specific ways to reach environmental performances according to the geographical, cultural and technical local contexts.( Bidou,2003) In the above analysed context, standardization and technical solutions can have a crucial role. Nevertheless they cannot bring best solutions by themselves. They can only be tools for both the decision-makers, the contacting authorities, the architects and the engineers. The way to use those tools will continue to be a matter of human ability to create built environment, with sensibility, technical competence, sense of dialog and experience. This has been the concluding major outcome of the Euro-Mediterranean
Athens Conference.
Endnotes :[1] This congress has been a Euro-Mediterranean co-operation and dissemination action in the frame of the Life-Environment Programme of the EU, and more specifically in the frame of the LIFE Project concerning “Enhancing transferability of innovative techniques, tools methods and mechanisms to implement sustainable building in the Mediterranean basin. It was at the same time, a regional Event prior to the Global SB05 Conference "Action for sustainability " held in
Tokyo , in September 2005. [2] The SD-MED Association “ Association for co-operation on sustainable development and construction in the
Mediterranean ” constitutes a Hellenic-French and international initiative, of non-profit character aiming at a multi-level and multi-dimensional cooperation around a common vision of sustainable development. As cooperation of personalities and technocrats but also mainly architects and engineers with specialisation and expertise on sustainable development and sustainable construction focuses on sustainable construction, considered as a action that can encourage the collaboration for the sustainable urban development and her application in projects that concern the building, the built environment, the city, the land planning, that is in projects of all territorial scales. SD-MED’s ambition is, besides, to contribute, if possible, to the drafting of the Mediterranean Strategy of Sustainable Development which is being prepared by the Mediterranean Action plan and by the Blue Plan as well, and to integrate as much as possible the sustainable building and construction dimension in the above strategy.
