Renewable Energy in Historic Buildings; The Capitol of Puerto Rico and its Annexes
Zusammenfassung
The Puerto Rico State Capitol
Superintendence (CS) is aligned with the new
energy management challenges that the world is
facing in order to reduce the energy consumption
and CO2 emissions levels. A payback period of a 5
year minimum is required. The improvements
options should be focused on the reduction of
energy consumption and greenhouse emissions by
the integration of new energy efficient technologies,
including Renewable Solar Energy, and Feedback
of the existing systems. The CS conducted an
energy audit Level II ASHRAE (American Society
of Heating, Refrigeration and Air Conditioning
Engineers) at the Capitolio facilities which
consisted on the evaluation of all installed systems
that make use of available energy sources. The
main objective of the energy audit is the
identification of new improvement opportunities
that can be deployed within the facilities by making
use of efficient and reliable energy systems. Finally
the installation of a 168 kW Solar Energy System
using the latest solar energy methodology and
technologies could be done and the achievement of
more than 30% of energy cost reduction with a
payback less than five year.
