LEED Points For Air Filtration
National Air Filtration Association
NAFA
member – U.S. Green Building Council
Mission - USGBC
“To transform the way buildings and
communities are designed, built and
operated, enabling an environmentally
and socially responsible, healthy, and
prosperous environment that improves
the quality of life”.

Meaning?
Let’s do everything we can possibly
afford to do that will help keep this
place neat for the next generation of
humans…

What Are We Really Talking
About?
Everyone is doing everything to be “green” ?
Green buildings and products still remain a
small percentage of the total market
Need to increase focus on greening
existing buildings-potential savings est.

LEED promotes a whole-building approach to
sustainability by recognizing performance in
six key areas of human and environmental
health for Existing Buildings:
Sustainable Site
Water Efficiency
Energy & Atmosphere
Materials & Resources
Indoor Environmental Quality (IEQ)
Innovations in Upgrades, Operations and
Maintenance

Preq.-Existing Building Commissioning
– Prepare a commissioning plan for carrying out the testing
of all building systems to verify that they are working
according to the specifications of the building operation
plan.
“Verify and ensure that fundamental building elements and systems
are installed, calibrated and operating as intended so they can
deliver functional and efficient performance. “

buildings and building systems so that they continue
to deliver target building performance goals over the
long term.”
NAFA Certified Technician (NCT) certifies individuals
who study the text, “Installation, Operation and
Maintenance of Air Filtration Systems,” and pass the
national exam

Indoor Environmental Quality
(IEQ)

Preq. - Establish minimum indoor air quality
(IAQ) performance to enhance indoor air
quality in buildings, thus contributing to the
health and well-being of the occupants.

of building occupants and maintenance
personnel to potentially hazardous particle
contaminants, which adversely impact air
quality, health, building finishes, building
systems and the environment. Establish and
follow a regular schedule for maintenance and
replacement of these filters. ”

Many points available for LEED in three major
categories
It the right thing to do
LEED 2009
LEED 2009 will incorporate highly anticipated regional credits,
extra points that have been identified as priorities within a
project’s given environmental zone. LEED has also undergone
a scientifically grounded re-weighting of credits, changing
allocation of points among LEED credits to reflect climate
change and energy efficiency as urgent priorities.
This will be one of the most significant changes to the rating
system, and will increase the importance of green
building as a means of contributing immediate and measurable
solutions toward energy independence, climate change
mitigation, and other global priorities.

apply.
Willing is not enough; we must do.”
