There are multiple benefits to utilizing advanced filtration via sorbent ventilation technology, which is allowed under ASHRAE’s Indoor Air Quality Procedure (IAQP) for calculating minimum ventilation rates. One such benefit is the acquisition of LEED points for a LEED project.
New Construction projects can achieve up to 13 LEED points by choosing IAQP for ventilation calculation compliance.
The USGBC has a performance-based indoor air quality design and assessment pilot credit (EQpc124), which allows buildings to utilize the IAQP to earn up to 7 LEED points.
Using the IAQP with air cleaning also helps buildings earn up to 6 additional points in the LEED BD+C Energy & Atmosphere credit area.
Existing projects can achieve up to 17 LEED points by choosing IAQP for ventilation calculation compliance.
The USGBC has developed the LEED O+M Performance-based indoor air assessment pilot credit (EQpc119) as an alternative compliance path to earning 9 LEED points in EQ and IN credit categories.
Using the IAQP method, outside air intake is reduced leading to energy savings, enabling up to an additional 8 points (non-pilot) for existing buildings in the Energy & Atmosphere credit area.
