In 1981, James Hansen, one of the most important climatologists in the world, starting from the researches into the ozone hole, revealed the risks of the global heating.

The “tenable” term was used, for the first time, in 1987, in the Burtland Report, published by the Worldy Commitee on Enviroment and Development, that declares: the tenable development is the one wich satisfies the present needs without compromising the future ones.

We have to wait ten years more as there are signed international agreements for the adoption of “urgent measures” suitable to reduce the emissions of the polluting elements.

The Kyoto protocol, as we know, compels the signed Countries to reduce polluting emissions coming from all the enviroments of a country-life. The treaty provides the duty of the industrialized Countries to reduce the polluting element emissions not less than 5.2% as to the emissions registered in 1990.

The Kyoto protocol provides the recourse to market mechanisms, the so-called Flexible Mechanisms: the main one, among them, is the Mechanism of Clean development among them. The aim of the Flexible Mechanisms is to reduce emissions at the less possible cost.

The 2002/91/CE directive invite all the member States to draw up some rules and laws for the control and the improvement of the energetic efficiency of the buildings, as to obtain the felling of the consumptions and a relative polluting reduction.

We can understand how we consider the energetic requirements an influence instrument of the worldly market-energy. Infact, the energy employed in the residential and tertiary sector, made of buildings for the most part, represents more than 40% of the final energetic consumption of the Community.

We must also underline how the attention falls not only upon the shell of the building(N.10 of the Directive 2002/91/CE), but also upon the system adopted for the heating and conditioning of the rooms, the employment of renewable energetic sources and the architetonic feature of the building so as in bio-architecture. With regard to such considerations it would be desiderable that all the states adopt the necessary measures to guarantee least(little) requirements of energetic efficiency of building are established...

These requirements are examined at regular exipiration that should not exceed five years and, if necessary, revise according to the technical progress in the building sector.

In the light of these observations, it’s evident that the organs and institutions, placed before, must stimulate the research of new solutions. Besides, it is of fundamental importance that the rules are revised on the basis of changing degree reached in order to obtain higher qualitative standards.

The latest Conference of the United Nations about the climate(COP15), wich happened in Copenhagen, was failed. The hard core of this international meeting was the negotiation for an enlargement of the Convention about climatic changes and for the signature of a new agreement about climate wich should have replaced the Kyoto protocol. Unfortunately, they haven’t signed any agreements to contain pollution leaving the choices to the decision of the single States.
