The solution
To achieve the desired energy savings, the
Sello Shopping Mall optimized its building
performance. The comprehensive modern-
ization reduced operating costs and in-
creased the value of the property.
To meet the objectives, the mall enhanced
its existing building management system
to facilitate the use of energy saving mea-
sures. In conjunction with the technical
improvements, the system has improved
air quality and lowered energy consump-
tion by up to 50%.
To be able to continuously optimize all
parameters, the building management
system is connected to an Advantage
Operation Center. Specialists evaluate the
data from the Energy Monitoring and
Controlling software. If needed, they
adjust the settings remotely.
These integrated measures created the
foundation for operating ventilation and
air conditioning systems with maximum
energy efficiency. The Sello service staff
was trained to optimize the ongoing
maintenance of the technical systems.
To ensure the economic success of this
project, Siemens issued a savings guarantee
as part of an Energy Performance Con-
tracting agreement and pre-financed the
required investments. This agreement
guarantees the mall annual savings of
at least 1,250,000 kWh of electricity,
1,300,000 kWh of thermal energy and
536 tons of CO
2
, corresponding to a reduc-
tion in energy costs of €133,000 a year.
During the term of the Energy Performance
Contract both sides agree on the amount
of savings that is used to pay off the in-
vestments; further saving surpluses are
shared. After the agreement has ended,
all the savings will go to Sello. An attrac-
tive perspective for Sello as the defined
payback period is only four years and as
additional energy services can ensure
ongoing savings.
Successful LEED certification and the en-
ergy savings and air quality improvements
achieved have convinced the owners of
the Sello Shopping Mall to make similar
upgrades to their other properties.
