IEC DESIGN H MOTOR.
An electric motor that meets
				all of the following:
1. It is an
			 induction motor designed for use with three-phase power.
2. It contains a cage rotor.
3. It is capable of direct-on-line
			 starting.
4. It has 4, 6 or 8
			 poles.
5. It is rated from 0.4 kW
			 to 1600 kW at a frequency of 60 Hz.
IEC DESIGN N MOTOR.
An electric motor that meets
				all of the following:
1. It is an
			 inductor motor designed for use with three-phase power.
2. It contains a cage rotor.
3. It is capable of direct-on-line
			 starting.
4. It has 2, 4, 6 or 8
			 poles.
5. It is rated from 0.4 kW
			 to 1600 kW at a frequency of 60 Hz.
INFILTRATION.
The uncontrolled inward air leakage
				into a building caused by the pressure effects of wind or the effect of
				differences in the indoor and outdoor air density or both.
INFORMATION TECHNOLOGY EQUIPMENT (ITE).
Items
				including computers, data storage, servers, network, and communication
				equipment.
INSULATION ENTIRELY ABOVE DECK.
A roof with all
				insulation:
1. Installed above
			 (outside of) the roof structure; and
2. Continuous (i.e., uninterrupted by framing
			 members).
INTEGRATED ENERGY EFFICIENCY RATIO (IEER).
A
				single-number figure of merit expressing cooling part-load EER efficiency for
				unitary air-conditioning and heat pump equipment on the basis of weighted
				operation at various load capacities for the equipment.
INTEGRATED HVAC SYSTEM.
An HVAC system designed to
				handle both sensible and latent heat removal. Integrated HVAC systems may
				include, but are not limited to, HVAC systems with a sensible heat ratio of
				0.65 or less and the capability of providing cooling, dedicated outdoor air
				systems, single package air conditioners with at least one refrigerant circuit
				providing hot gas reheat, and stand-alone dehumidifiers modified to allow
				external heat rejection.
INTEGRATED PART LOAD VALUE (IPLV).
A single number
				figure of merit based on part-load EER, COP, or kW/ton expressing part-load
				efficiency for air conditioning and heat pump equipment on the basis of
				weighted operation at various load capacities for equipment.
INTEGRATED SEASONAL COEFFICIENT OF PERFORMANCE
				(ISCOP).
A seasonal efficiency number that is a combined value based on
				the formula listed in AHRI Standard 920 of the two COP values for the heating
				season of a DX-DOAS unit water or air source heat pump, expressed in
				W/W.
INTEGRATED SEASONAL MOISTURE REMOVAL EFFICIENCY
				(ISMRE).
A seasonal efficiency number that is a combined value based on
				the formula listed in AHRI Standard 920 of the four dehumidification moisture
				removal efficiency (MRE) ratings required for DX-DOAS units, expressed in lb.
				of moisture/kWh.
INTERNAL CURTAIN SYSTEM.
A system consisting of
				moveable panels of fabric or plastic film used to cover and uncover the space
				enclosed in a
greenhouse
on a daily basis.
ISOLATION DEVICES.
Devices that isolate HVAC zones
				so they can be operated independently of one another. Isolation devices include
				separate systems, isolation dampers and controls providing shutoff at terminal
				boxes.
