Abstract
The main purpose of this study was to conduct a study for improving energy
efficiency of an important building in Rome, the Headquarters of the Italian State
Monopoly. The study was conducted by comparing conventional analysis tools
with innovative ones, in order to evaluate the possible solutions, both structural
and plant, aimed at the use of renewable sources and at energy saving. After
making a thermo graphic survey, the first and useful step for a good energy
audit, conduct building energy was simulated, at first in steady state by the use of
a software widely used at the professional level, then in transient state by the use
of TRNSYS, a finite difference method software which is able to simulate more
accurately conduct building energy. The next step was to propose possible
redevelopment of a structural and energy plant that promotes the building energy
rating higher, finding the right balance between the energetic and economic
aspect. Among the interventions plant, two possible workarounds have been
proposed and designed in detail:
installation of a photovoltaic system;
installation of a solar cooling system.
Both solutions lead to a reduction of electricity consumption with a
significant impact in economic and environmental terms.
Keywords: energy efficiency, energy saving, steady state, transient state,
photovoltaic system, solar cooling system.
