14. WHAT IS DEMAND SIDE MANAGEMENT ?
DSM mentions initiatives and technologies that encourage
consumers to optimize energy use. The benefits of DSM are
generally divided into two.
STUDENT UNIVERSITY
Decrease
amount of
electricity used
and adjusting
the time
Shifting energy
consumption
from peak to
non-peak hours.

systems. KNX provides a comfortable and functional
installation with its open feature.
 It can integrate all systems used in commercial
buildings. Consumption values can be significantly
decreased.
