The ARAEN, Abruzzo Regional Energy Agency, for the three years of experimental activity, has been created through the European SAVE II project with approval granted by the European Commission with contract nr. ENER/4.1031/A/99-006.It was established with Regional Law n. 6/2005
FIELD OF ACTIONFIELD OF ACTION Energy Saving: Increase energy efficiency in public and private
constructions, services and in the industry Promote the use of energy saving building
techniques and materials, both in the public and private sectors.
Renewable Energy: Support the regional energy policies relating to the
development and use of renewable sources:
◦ Biomass, Mini Hydraulics, Thermal Solar Power,
Photovoltaic Solar Power, Wind Power
Directive 2002/91/ECDirective 2002/91/EC Energy performance of buildings
Promote the energy efficiency in the buildings and houses with cost-effective techniques keeping into account the local and weather conditions inside and outside the building.
Directive Directive 2002/91/EC2002/91/EC
The four key points of the Directive are:
a common methodology for calculating the integrated
energy performance of buildings;
minimum standards on the energy performance of new
buildings and existing buildings that are subject to major
renovation;
systems for the energy certification of new and existing
buildings and, for public buildings, prominent display of
this certification and other relevant information.
Certificates must be less than five years old;
regular inspection of boilers and central air-conditioning
systems in buildings and in addition an assessment of
heating installations in which the boilers are more than 15
years old.

D. Lgs. 192/05, modified by D. Lgs. 311/06
o Criteria, conditions and methods to improve the energy performance of the buildings to promote the development, the enhancement and the integration of renewable energy sources.
o Contribute to limit the CO2 emission as to reach the Kyoto protocol objectives.
o Promote the competitiveness through the technology development.

Energy Performance Certificate
Energy Performance Energy Performance CertificateCertificate
Energy Performance Certificate presents the energy efficiency of dwellings on a scale of A-G
The most efficient homes - which should have the
lowest fuel bills - are in band AThe certificate uses the same scale to define
the impact a home has on the environment
Better-rated homes should have less
impact through carbon dioxide (CO2)
emissions

Energetic: consumption reduction Environmental: less use of fossil
fuels with strong emissions reduction Economic: energy saving leads to
economic saving Social: renovation and valorization of
the social houses and improvement of the living conditions of the tenants
Advantages
Improvement of the structures quality, of the energy efficiency of the existent old building and of the technological components
Realization of more efficient plants (solar hot water panels)
Use of bioclimatic techniques to improve the thermal efficiency of the building
Use of ecologic construction materials
