Abstract
From the study on the analysis of the cycle of life of the plant of heating
and conditioning it emerges that the greater environmental damage is caused by
the use of the plant of conditioning.
From the comparison of the two analyses it is drawn that in both the trials the
most greater impact is due to the and energy consumption, electric for the plant
of conditioning, gas methane for the plant of same heating. From the results
that despite the trial that brings less damage to the environment both that of
heating, is the production of gas methane, used for the heating, more dangerous
that the production of electric energy.
This means that if the two fittings were equal but one fed to gas and the other
to electric energy, the most greater impact you/he/she would be caused by what
uses the gas methane.
In the study the case is considered in also which are not you are consumed
energetic from the two fittings, to ascertain what component and what substances
were more serious on the environment. Of it that the present copper results in
the batteries of thermal exchange of the unity of treatment of the centre of
conditioning, and in the exchangers of heat of the thermal the centre for the
heating, it is what produces greater environmental, even if very inferior damage
to that product from the electric energy; in fact in the production of the
copper sulphuric anhydride is sent forth (SO2).
For the reduction of the environmental damage, more than the substitution of
parts of the plant with others of smaller impact, the accent is set on the
energetic saving.
The architectural planning in the last years, has assembled the attention on the
energetic theme, underlining the so many wastes of the today's one to live.
In the last decades the buildings realized by the energetic point of view have
been how much more inefficient can be imagined: the use of perishable structures
in reinforced concrete and the illusion to simplify the constructive systems has
determined problems of thermal bridges and enormous dispersions of heat; the
tendency to increase the surfaces glass door of the buildings has given strong
problems of winter thermal dispersion and strong problems of summer overheating
of the buildings; the total indifference for a correct exposure of the buildings
to the sun has reduced the opportunity to use the natural illumination
determining an increase of the energetic wastes.
To the light than motto is chosen to intervene on the building with an energetic
restructuring.
From the comparison of the cycle of life of the plant of the restructured
building and the plant of project results once more that the energetic saving
reduces the environmental impact.
To offer good levels of environmental comfort but at the same time to minimum
reduce the use of the polluting energetic resources, can be proceeded also
further to an energetic retrofit to the use of sources energetic renewable
cleaning up as the solar energy; conducted of air underground for condition the
air, surfaces glass door or turned greenhouses to south to trap the heat in
winter, innovative transparent materials for "to select" the solar
radiation, solar fireplaces to increase the natural ventilation, use of
photovoltaic panels to produce electricity.
These are alone some of design strategies that can be applied for decreasing the
energetic consumption, but above all to improve our quality of life.
