The framework
for engineering a greener future
Increasing population, the rising
expectations of comfort and modern
architecture constantly reaching for
the sky are all creating new demands
for the ventilation systems and
air handling units. In parallel, the
focus is now higher than ever on
developing technologies that would
reduce energy consumption and CO
footprint of modern buildings.
Europe has been active in
standardizing eciency
requirements for motor systems. EN
50598 series – a standard on how to
determine the eciency of motor
driven systems – was published in
2016 and has now been converted
into a global IEC standard: the IEC
61800-9 series. The foundation for a
potential regulation of the eciency
requirements are now in place. The
behavior of the driven machine is
the subject of standards from ISO,
and the rst drafts of a standard
for pumps will soon be published.
The eciency requirements in the
forthcoming Lot 30 are a good start
but they only address the motor and
variable speed drive, not the whole
system which is the key to energy
eciency.
According to European Ecodesign
requirements for Ventilation
Units (Residential as well as Non-
Residential), in EU it’s required
that the ventilation units (AHU) is
equipped with a minimum three
speed drive or an AC drive.
Also, in accordance with EU studies,
starting with January 1st, 2018, the
ventilation unit must be equipped with
a lter monitoring device alarming
when the lter must be replaced.
