Monthly production/use of electrical energy in 2012
The year 2012 was the first full
year of operation for the business
building Kobra. During the year a
familiarization with the building
and its system took place. The
search for optimum operational
settings was of key importance,
a process that is and will remain
on-going.
By monitoring the building we
established (shown in graph 1)
that the largest energy consumers
in the building were the lighting
and IT equipment - in 2013 the
investor made the next step in
energy efficiency by implementing
LED lighting.
Based on the heating related
specific energy use and total energy
use we can state that the building
meets the passive standards. By
changing the lighting in 2013 the investor
has achieved a plus energy
building, which produces more
energy than it uses.
