Buildings Consume Massive Amounts of Energy
• Commercial Buildings consume
massive amounts of Energy
– Electricity = 74% of the energy
consumed by commercial buildings
•
(source: US DOE, 2008 Building Energy Data Book)
• Half of electricity consumed by
buildings is used to move air
– More than half of the worlds energy is
consumed by pumps and fans
An electric motor is a fixed-speed machine

VFDs Greatly Reduce Electricity Use
• (VFDs) significantly reduce
electrical consumption
– Most pump and fan systems are
oversized to account for maximum loads
– Capacity usually exceeds demand
– Application of VFDs converts systems to
variable flow
• Green House Gas Reduction
– 80% of commercial building CO2
emission due to electricity consumption
VFDs provide the ability to vary the speed of a motor

Why Do It? Less Energy = Greater Savings
Affinity laws Express relationship between rotational speed and flow, pressure and power
Flow is directly proportional to speed
Pressure is proportional to the square of speed
Power is proportional to the cube of speed
% Power Savings = (%Speed Reduction)3
