-    the amount of energy that can be reduced from the consumption specific to the building;

-    the percentage of the supply of clean energy from renewable sources as opposed to the total amount necessary;

-    the reduction of the consumption of energy produced conventionally

-    the decrease of the exploitation costs of the building;

-    the reduction polluting emissions.

Although the proposed project fits, through its objectives and priorities in the objectives of Programme 4 corresponding to the research direction 2 – Energy, through its connections and effects it also fits naturally in the thematic areas 6 - Environment and climatic changes as well as in 1 – Health (the efficient and lasting administration of natural resources, the reduction of the negative impact on the environment generated by human activity, the ensurance of human health).

All along the evolution of the domain, people have erected higher and higher buildings which are also more exposed to the outer climatic environment. Thus, soil has been considered a host only for foundations and elements of infrastructure, the rest of the building remaining under the direct influence of environment factors.

At present, the most difficult problem is generated by the high consumption of energy and implicitly of fuel, necessary to correct what weather makes unacceptable from the point of view of the demands imposed by man’s interior comfort. The seriousness of the consequences of this fact is obvious when we look at the global consumption against the state of the environment, due to the polluting emissions that can even endanger life on Earth.

Within this context it follows that the idea of a compromise with respect to building in the environment is obvious. Why not build by observing the balance offered to us by nature? It is clear that when there is no human intervention, the environment is in a state of equilibrium. The soil stores energy from the sun and loses energy during nighttime, thus creating with the terrestrial atmosphere a balanced system. Where these interdependent balance limits are naturally or artificially exceeded, living conditions become difficult or even impossible. As a result, whatever man builds as an element that physically and phenomenologically comes between the climatic environment and the soil should be conceived so as to aim towards maintaining the same soil-atmosphere equilibrium.

This may be achieved by accepting the compromise of building so that the part of the building that stands above the ground be in an energetic balance with its underground part. The task of research is to comprehend and discover how this aim can be attained without putting any further energy into the system, energy produced conventionally and having high economic and environmental costs.

The proposed project has the role of providing solutions to this complex problem that involves:

-         in-depth knowledge of the soil-climatic environment equilibrium;

-         research in technical physics;

-         architecture and constructions;

-         material technology;

-         new technologies in instalations, conversion and generation of energy;

-         constructions economy and economy in the field of energy management;

-         information technology.    

The aims specified by the European Directive 2002 / 91 / EC concerning the energetic performance of buildings as well as the national legislation that translates, at the present stage, this directive (the 199 / 2000 Law concerning the efficient use of energy, the 325/ 2002 Law for the approval of the government decree concerning the rehabilitation of the existing building stock and the stimulation of energy saving) correlated with the objectives stipulated by the European legislation on the resources of renewable energy ( the 2001 / 77 / EC Directive concerning the promotion of the electric energy obtained from renewable sources, the 1994 European Charter on Energy, a series of Resolutions and Recommendations of the European Council and the national legislation such as the HG 443 / 2003 concerning the promotion of the electric energy obtained from renewable sources, the HG 1535 / 2004 concerning the approval of the strategy of capitalization of the renewable energy sources), lead towards the necessity and acceleration of the actual application of the policy on energetic efficiency exploitation of renewable energy sources, which are capable of providing energy without harming the environment. The above-mentioned European and national legislation implies a programme of extension of the degree of capitalization on the renewable energy sources until 2010 and on long term.  

        The aim of the project is to establish the defining elements and to create the theoretical model and a pilot building model for a new concept of constructing a building with high energetic autonomy, whose energy consumption from conventional souces would become insignificant in relation with the total necessary energy, which will be mainly covered by the energy produced in the covering itself. The pilot model is conceived as an experimental model on which innovating solutions will be implemented for elements and components of the covering-specific energy generator type (double-layer panels, facade elements with various compositions and structures with pasive or active energy-collecting elements etc) and on which there will be verified their functionality and efficience in exploitation, their enhancement and future experimental research.
