sustainable requalification

When you think of sustainability in all runs immediately thought to energy needs. Some people also think about other environmental issues. And stop here the most.
In reality the concept of sustainability and reduce it to very large and energy needs and environmental concerns is always reductive. The energy is certainly an important factor. The buildings must not consume more than necessary.
And according to present knowledge this need is reduced almost to zero. In construction it is about a factor of 10 reduction: You can consume 10 times less than the current building stock (Moving from 200 kWh / MQA’s national building stock to less than 20 kWh / MQA needed for a home designed with appropriate criteria) in conditions of service charge, if not better.
All with the materials and technologies also currently available only through better care and knowledge of the thermal issues. Much of the definition of this knowledge comes from central Europe and is calibrated on the temperature requirements of typical winter. In the latitude of the center-south Italy needs insulation esitivo are at least as important than winter.
What we are experiencing is therefore a transitional phase in which methods should be learned and Central Europe declined with requirements Mediterranean. Let me explain: when the problem is to keep the heat inside a room, everything we need to isolate it from the outside.When the problem is instead of keeping cool indoors, then the heat supply data from internal sources (people, lighting, appliances, plants) and from outside through the windows (sun) affect predominantly. The insulation in this case does not help us: in that it prevents heat to escape from the package.
The solution is well known and experienced historic buildings of all hot and very humid countries is to introduce the mass. The mass allows to stabilize the internal temperature of dampening the peaks data from the temporary presence of people and other thermal loads, and closer to the average values ​​of the outside air. If we evaluate the values ​​of monthly mean air temperature the more we realize that we can approach them, the greater the comfort of living and reduced or canceled will be the need for mechanical cooling.Of course, the environmental problem is much broader and related to many other factors, such as national vice president INBAR 1 – 2 National Institute of Bio-Architecture Moving from 200 kWh / MQA of the national building stock to less than 20 kWh / MQA needed for a home designed with appropriate criteria. For example, pollution and fine particles, the permeability of soil quality and quantity of waste and wastewater, water resources etc..
But what I want to emphasize is the message that we can not reduce preblema solutions to the sustainability of the technical facts.
It should be a rather radical change of mentality to understand that the question that our society must ask is not how much we save with insulation or PV, but what we do with those savings. Because if every time we get a saving per unit of output continue to increase overall consumption, in constant search of fuel, not traguardiamo the goal of sustainability. So sustainability is not something only technology, but something strictly dependent on the attitude and vision of man.
If human needs are not satisfied, if not satisfied with the quality research that allows us to a life fulfilled with the tangible and intangible assets that are given, always continue the quest for satisfaction that our consumer society wants and always lead to promises to fulfill.
So the only way that an area satisfies the needs of its inhabitants as it is in harmony with that place and in continuity with its history, reflected in the customs and thoughts of that community. The territory is one and continuous. This does not mean that you do not ssano bit and do not go to a cultural and historiographical identified temporal layers of a city, far from it.
Always the fabric of an area will be moved, growing up, going, rising and shrinking even in different directions, with progressive stratigraphic always fairly well identified: the Greek city, the Roman city, the medieval, Renaissance, Baroque, nineteenth century, and so on. But this identification of stratigraphic data in itself is something very different from the parameterisation of safeguard zones of urban contemporary art, where the protection is inside, outside is freedom. This perimeter is a completely abstract force that flows from our vision of the world Cartesian geometry, for which we decompose gradually to analyze the object of analysis in the sub-elements gradually more defined, gradually losing the vision of the whole and how it functions. This analytical approach allowed us tremendous progress over the centuries, has allowed us to outperform companies with millennial opposite setting and much more evolved than ours, like China, has enabled the advancement of science, particularly precisely in those matters where for the benefit of all scomposiziosassne subunits in more analytically definable. But the progressive blind faith in the Cartesian coordinate system and its application in all fields of study, it is this necessity that forced more and more we hear, to apply charges to the analytical evaluation of all matters of our lives, the belief that only the demonstration of analytical and then allows the demonstration of scientific truth, the very word “scientific”, itself a synonym for the more of truth and indisputable demonstration than through other and more scientific evidence, well, this world view, though well suited to the mechanical and ‘engineering, creates damage, and forced and twisted logic when it becomes the only canon in humanities subjects such as psychology, medicine, architecture and urbanism.

It ‘clear that the progress of surgery-data from this particular world view and breakdown of trust in the scientific-analytical-were formidable. It ‘s also clear the limits of medicine when the problem is rather psychosomatic, and that although it is obviously our psyche to guide all of our choices, do we really know very little about how to interact with it and eventually heal. But because of the discrediting of all those matters that can not be absolved only by the method-Cartesian science. The same architecture and urbanism, considered starting from 800, century engineering, younger sisters and worn in a continuous effort to imitate, and those canons of scientific research that they can trust blindly. Hence since the early decades of the Bauhaus 900 home-living machine, the modernism of the syllogism form and function, and finally the contemporary architecture with its lexical and energy.
Droves of architects have devoted time to time with all their energies to one or another school of thought, and then intimately perceive the incongruity of what they were doing and lead to counter-movement characterized by the explosion of completely free , dell’avulso from the context, style dell’autoreferenzialismo Gehry. Obviously the architecture is not only and solely on technique: the architecture has to do with communication and must interact with people, and our perception of the world is organic-thus essentially non-analytic functions on the comprehensive plan of communication ‘architecture. Then the organic approach is homeopathy, which solves the problem is not looking only to its manifestation, but seeking out the origin intimate. And ‘what with little – nothing to that of the less-careful get a change of course invisible and newspapers acting on ganglia of an organism.If the goal of all our efforts is the machine housing, the home unique and perfect, our efforts will be useless and obviously rejected. From war we lost the geographical and historical context with, thanks to the technology available, more and more industrialized and versatile. The resources available have grown and the parameters with which to apply them have failed. We can produce structures with a much greater degree of freedom than once, but the result is worse. The reason for this is precisely the loss of reference. If we look at an old town, the beauty of the buildings is not the solution obtained and put on display by each designer, but in the harmony of all the buildings. It ‘just that sense of dialogue that has the force of an urban fabric that has been lost. We are able to make a nice car, but we are no longer able to make a square, and parking is the ultimate expression of degraio of our territory. We are able to draw a cup, but we are in trouble imbandire a nice table. We are at best able to furnish a room, but in difficulty compared to the living room of a city.
What I mean is that the historic center of Nocera is so because it is in Nocera, and a surrounding area, geographically as historically understood absorbs its characters. Think of the qualifications of the old town and other than the distinct enhancement of the surrounding area is not a company itself can bear fruit, and therefore probably not sustainable in the long run. I mean that the quality of a piece of land can not be too different from what you see around you, and that the differences tend to offset both positive and negative for a natural osmotic effect.Valuing a mean old town and then think about the value of an entire area, designed in synergy not just in urban planning and architecture, but the system of environmental, social, cultural and economic. Valuing be understood not so much and only as protection but as a system of promotion and incentives. The mere preservation of a status quo is not sustainable for a long time if the system does not track the movements and demands of society, ending the long run for scollarsene and become, as sometimes happened in some city centers: the ghetto left in the hands the poorest sections of society. This last step means that the elevation is such that the protection and constraints-urban, sanitation-are such as to make it desirable that in many ways but could express standards of quality. The question of the historical center is not intended as far as the focus of protection in urban area. There is no I frequenter of city centers, absorbing the beauty and benefits of a quality urban landscape, enjoys a convivial, casual encounters, walking, and I another, that all this has nothing to do and when it crosses the remaining quarters off the senses and does not interact with the territory. No. The area is one and continuous.
