Indoor Air Quality and LEED Sampling

Businessman in Office Building LobbyThe quality of indoor air inside offices, schools, and other workplaces is important not only for workers’ comfort but also for their health. Poor indoor air quality (IAQ) has been tied to symptoms like headaches, fatigue, trouble concentrating, and irritation of the eyes, nose, throat and lungs. Also, some specific diseases have been linked to specific air contaminants or indoor environments, like asthma with damp indoor environments. In addition, some exposures, such as asbestos and radon, do not cause immediate symptoms but can lead to cancer after many years. Many factors affect IAQ. These factors include poor ventilation (lack of outside air), problems controlling temperature, high or low humidity, recent remodeling, and other activities in or near a building that can affect the fresh air coming into the building. Sometimes, specific contaminants like dust from construction or renovation, mold, cleaning supplies, pesticides, or other airborne chemicals (including small amounts of chemicals released as a gas over time) may cause poor IAQ.

The SRP Environmental Indoor Air Quality (IAQ) Division has over fifty years of experience conducting IAQ evaluations.  Our team of experts will utilize state-of-the art technology to augment visual inspections and occupant interviews.  The National Institute for Occupational Safety and Health (NIOSH) “Guidelines for Schools and Commercial Buildings” as well as” IICRC S520” are among the guidance documents our experts will follow in conducting your IAQ investigation.    Common IAQ problems such as Fungal Contamination, Volatile Organic Compounds (VOC’s), Bacterial Contamination, Particulates and Allergens will be evaluated.

LEED 3.2 IAQ Sampling

SRP Environmental can perform the components of the Environmental Protection Agency (EPA) “Testing for Indoor Air Quality 01 81 09” as part of the Leadership in Energy and Environmental Design (LEED) NC-3.2.  A sampling strategy is developed based on the size of the building and number of HVAC systems supporting the building.  Samples are collected and analyzed for

  • Formaldehyde
  • VOC’s
  • PM10
  • 4-PCH (if Styrene/Butadiene backing is used in the carpet glue)
  • Carbon Monoxide

All air samples are analyzed by an American Industrial Hygiene Association-accredited laboratory.  SRP Environmental can also assist compliance with LEED requirements such as:

  • Assisting with ventilation and comfort requirements
    • ASHRAE 62.1 2004
    • ASHRAE 55-2004
  • Confirming negative pressure pollution sources
  • Oversight during construction
  • Selection of building materials
  • Measuring and confirming light levels
  • Pre-occupancy air testing
