Example :
One complaint per month and per floor, for a period of 20 years.
1 X 12 X 20 X 150.00$ = 36 000.00$
Which is about 1.80$ per sqf on 20 years.

• Production loss
• Discomfort
• Absenteeism
• The loss of a tenant
• Complaints management

Eliminated baseboard heaters
The induction in the occupied zone increased by approximately 15 times the primary air.
The induction homogenize the temperature and the density of the air. (Allows better air down)
The induction allows to get the air from the low part of the room.
The induction allows to heat only by the ceiling.

Section 4.1
ENERGY SAVING
Reduction of the overheating between ceilings.
• Decreasing by approximately 5°C the temperature
differential between the ceiling and the outside.
( Reduction of heat loss by the roof)
Recovery of the ambient heat
• Effective recovery of the heat from the lightning source
• Recovery of the other sources of heat
(computer equipment : ± 20%, occupants : ± 15%)
• Low demand for heating the thermostat thanks to
homogeneous distribution of the heat

Section 4.2
ENERGY SAVING
Energy saving on heat, humidification and
air conditioning of the new air
Reduction of 20% the quantity of new air required per person.
( See section 1 . Improvement of the quality of air according to ASHRAE ; standard 62. 1-2007)
Annual saving of about 2085$ per office area of 15,000 sq.ft

Section 4.3
ENERGY SAVING
Reduction of the overventilation, overclimatisation and
overheating in the central zone
The decrease in the overventilation in the central zones often avoids the overclimatisation and
therefore the overheating to compensate for this one.
(See section 3 ; Reduction of approximately 50% of the central air and ducts in the central areas
by the interpretation of “making induced air”)
Economy of approximately 3 376$ per year for a local of 15,000 sq.ft.

THE FLEXIBLE DUCT DIFFUSER FDD

Section 7.2
THE FLEXIBLE DUCT DIFFUSER FDD
The induction
• Several holes of various diameters work in obtaining a very high rate of induction.
• The small holes shall ensure that the air propelled to the output of the holes, at high speed,
produce an effect of moving a large quantity of ambiant air around them.
• There is then a heat exchange with the air in the vicinity of the diffuser and FDD,
these temperature differences quickly become isothermal..

Section 7.3
THE FLEXIBLE DUCT DIFFUSER FDD
Air Flow Path
Offers a multitude of mode of dissemination of air through the
positioning and dimension of perforation.
Each diffuser FDD NAD Klima is manufactured to precise specifications
of local and unique. Therefore, it will reach the desired
performance in the environment and customer needs.
