6. About leed

11. What is green building? Design and construction practices that meet specified standards, resolving much of the negative impact of buildings on their occupants and on the environment.
So what is a green building anyway? Design and construction practices that meet specified standards, resolving much of the negative impact of building on their occupants and on the environment.

16. Great, so what?

25. LEED V3
TRIED AND TRUE

26. 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 c1.5 – 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

27. LEED New Construction

28. 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
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.

29. 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.

30. 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.

31. LEED for Existing Buildings

32. 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.

33. 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.

34. 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.

35. 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
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

36. 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.

37. LEEd for homes

38. 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
