What is LEED?
LEED, or Leadership in Energy and Environmental Design, is transforming the way we think about our indoor environments- where many people spend over 90% of their time. LEED provides building owners and operators with a framework for identifying and implementing practical and measurable green building design, construction, operations and maintenance designs. Developed by the U.S. Green Building Council (USGBC) in 2000, LEED certification provides independent, third-party verification that a building project meets the highest green building and performance measures.
Benefits of LEED Certification:
- Green building is cost-effective
- Lower operating costs and increased asset value
- Conserve natural resources, lowering both utility bills and impact on the environment
- Healthier and safer for occupants
- Reduce harmful greenhouse gas emissions
- Qualify for tax rebates, zoning allowances and other incentives
- Demonstrate an owner’s commitment to environmental stewardship and social responsibility
LEED IEQ Credit 3.2 Construction Indoor Air Quality Management Plan – Before Occupancy
This certification’s intent is to reduce indoor air quality (IAQ) problems resulting from construction or renovation to promote the comfort and well-being of construction workers and building occupants. LEED IAQ 3.2 credit requires an IAQ Management Plan, which can be achieved through one of two methods. Baseline indoor air quality (IAQ) testing can be used to demonstrate the contaminant maximum concentrations listed below are not exceeded:
|Formaldehyde||27 parts per billion (ppb)|
|Particulates (PM10)||50 micrograms per cubic meter|
|Total Volatile Organic Compounds (TVOC)||500 micrograms per cubic meter|
|4-Phenylcyclohexene (4-PCH)||6.5 micrograms per cubic meter|
|Carbon Monoxide (CO)||9 part per million (ppm) and no greater than 2 ppm above outdoor levels|
LEED V4 New Construction – Indoor Air Quality Assessment
After construction ends and before occupancy, but under ventilation conditions typical for occupancy, conduct baseline IAQ testing using protocols consistent with the methods listed in Table 1 for all occupied spaces. Use current versions of ASTM standard methods, EPA compendium methods, or ISO methods, as indicated. Laboratories that conduct the tests for chemical analysis of formaldehyde and volatile organic compounds must be accredited under ISO/IEC 17025 for the test methods they use. Retail projects may conduct the testing within 14 days of occupancy.
Demonstrate that contaminants do not exceed the concentration levels listed in Table 1.
|50 µg/m³ (Healthcare only: 20 µg/m³)
|Carbon Monoxide (CO)||9 ppm and no more than 2 ppm above outdoor levels|
|Formaldehyde||27 ppb (Healthcare only: 16.3 ppb)|
|Total Volatile Organic Compounds (TVOC)||500 µg/m³ (Healthcare only: 200 µg/m³)|
|Target Volatile Organic Compounds (35)||Varies per compound (Table 1)|
