TRIED AND TRUE
HOW DOES FILTRATION APPLY?
LEED NC /LEED CI - 3 points (7.5%)
• IEQ c3.1
• IEQ c3.2
• IEQ c5
LEED EBOM – 1 Prereq and 2 points (5%)
• IEQ p1 – Minimum indoor air quality performance
• IEQ c1.4 – Reduce particulates in air distribution
• IEQ c1.5 – IAQ Plan for facility alterations
LEED Homes 1 Prereq and up to 2 points (4.5%)
• IEQp7.1 – Good Filters
• IEQc7.2/7.3 – Better/Best Filters
LEED NEW CONSTRUCTION
IEQ C3.1 – DURING CONSTRUCTION
If permanently installed air handlers are used during construction,
filtration media must be used at each return air grille that meets
one of the following criteria below.
• Filtration media with a minimum efficiency reporting value
(MERV) of 8
• Filtration media is Class F5 or higher, as defined by CEN
Standard EN 779-2002
• Filtration media with a minimum dust spot efficiency of 30%
or higher and greater than 90% arrestance on a particle size of
3–10 µg
Replace all filtration media immediately prior to occupancy.
IEQ C3.2 – INDOOR AIR QUALITY
MANAGEMENT PLAN, BEFORE OCCUPANCY
After construction ends, prior to occupancy and
with all interior finishes installed:
• Install new filtration media and perform a
building flush-out by supplying a total air
volume of 14,000 cubic feet of outdoor air per
square foot (4,500 cubic meters of outdoor air
per square meter) of floor area while
maintaining an internal temperature of at
least 60° F (15° C) and relative humidity no
higher than 60%. Replace filtration media
after flushout is complete.
IEQ C5 – INDOOR CHEMICAL AND
POLLUTANT SOURCE CONTROL
In mechanically ventilated buildings, each ventilation system that
supplies outdoor air shall comply with the following:
• Particle filters or air cleaning devices shall be provided to clean
the outdoor air at any location prior to its introduction to
occupied spaces.
– Filtration media is rated at a minimum efficiency reporting value (MERV)
of 13 or higher
– Filtration media is Class F7 or higher, as defined by CEN Standard
EN 779: 2002
– Filtration media has a minimum dust spot efficiency of 80% or higher
and greater than 98% arrestance on a particle size of 3–10 µg.
• Clean air filtration media shall be installed in all air systems
after completion of construction and prior to occupancy.
LEED FOR EXISTING
BUILDINGS
IEQ P1 – MINIMUM INDOOR AIR QUALITY
PERFORMANCE
Implement and maintain an HVAC system
maintenance program to ensure the proper
operations and maintenance of HVAC
components as they relate to outdoor air
introduction and exhaust.
IEQ C1.4 – REDUCE PARTICULATES IN
AIR DISTRIBUTION
To reduce exposure of building occupants
and maintenance personnel to potentially
hazardous particulate contaminants, which
adversely affect air quality, human health,
building systems and the environment.
IEQC1.4 CONTINUED
Each ventilation system that supplies outdoor air shall comply with the
following during the performance period:
• Particle filters or air cleaning devices shall clean the outdoor air at
any location prior to its introduction to occupied spaces.
• These filters or devices shall meet one of the following criteria for all
outside air intakes and inside air recirculation returns:
– Filtration Media is rated a minimum efficiency reporting value
(MERV) of 13
– Filtration media is Class F7 or higher, as defined by CEN
Standard EN 779: 2002
– Filtration media has a minimum dust spot efficiency of 80% or
higher and greater than 98% arrestance on a particle size of 3–10
µg
• Establish and follow a regular schedule for maintenance and
replacement of these filtration media according to the
manufacturer’s recommended interval.
IEQ C1.5 – IAQ PLAN FOR FACILITY
ALTERATIONS
If permanently installed air handlers are used during construction,
filtration media must be used at each return air grille that meets
one of the following criteria below. Replace all filtration media
immediately prior to occupancy.
• Filtration media with a minimum efficiency reporting value
(MERV) of 8
• Filtration media is Class F5 or higher, as defined by CEN
Standard EN 779-2002
• Filtration media with a minimum dust spot efficiency of 30%
or higher and greater than 90% arrestance on a particle size of
3–10 µg
IEQ C1.5 CONTINUED
After construction ends, prior to occupancy and with all interior
finishes installed, install new filtration media and perform a
building flush-out by supplying a total air volume of 14,000 cubic
feet of outdoor air per square foot (4,500 cubic meters of outdoor
air per square meter) of floor area while maintaining an internal
temperature of at least 60° F (15° C) and relative humidity no
higher than 60%.
Replace all filtration media after
flushout is complete.
LEED FOR HOMES
IEQ 7 – AIR FILTERING
• Requirement – use
MERV 8 Filtration
• IEQ7.2/7.3 –
Better/Best Filters –
use air filters that are
MERV 10 or MERV 13
