Abstract
On-site energy management is one of the key strategies
toward improving energy efficiency and reducing CO2
emissions in the building sector. The Japanese energy
supply situation has changed drastically before and after
the nuclear power plant accident in 2011 because the
power plants operation has been restricted considering
safety. Since the energy market prices and CO2 emission
factors of electricity generation have changed, it is
expected that the potentials of on-site energy management
will also have changed.
This article describes the potential for energy sharing
between four different types of Japanese buildings with
their own on-site combined-heat and power (CHP) energy
generation, and models the performance of different
scenarios considering CHP operation strategy, energy
market price and CO2 emission factors. Comparison of
primary energy consumption between individual and
combined scenarios shows that the potential advantages of
energy sharing are determined by the combinations of
buildings and the CHP operation strategy. Moreover, if
the CHP operational modes are optimised, then energy
sharing provides greater advantages of reduced operation
cost and CO2 emission under market conditions where the
power supply configuration of the centralized generation
is subject to change.
