- Indoor Environmental Systems, Inc. provides energy efficiency and indoor air quality assessments.
- These services are provided to real estate transactions, insurance claims, allergy and asthma suffers, and those that want to make their building more comfortable, safer, and durable.
- There are many variables affecting energy efficiency and IAQ. The goal of our inspection is to discover the location of air leakage and IAQ issues.
- Our pictorial reports are easy to understand and state the causes of any IAQ issues and the remediation services needed. The reports prioritize services and itemize costs.
Level 1 Assessment:
-
IES certified inspector will visually inspect the building for air leakage, and indoor air quality issues. Air leaks tend to occur in the floors, walls, windows, doors, plenums, dropped or boxed ceilings and attic floors.
-
Of special concern is “Stack Effect”. Stack Effect happens when warm air rises and leaves through holes at the top half of the building.
-
Air leaving the top of the building causes air from the lower half (especially crawlspace’s and underground parking areas’) to be drawn into the building.
-
IES will inspect the crawlspace looking for water, mold, and insects. The condition of the insulation, air leaks into the home and drainage will be assessed.
-
IES will inspect the air ducts for leaks, mold, allergens, and damaged insulation.
-
IES will inspect the occupied areas of the building examining the air balancing, air filtration, humidification, and ventilation systems.
Level 2 Assessment:
-
This inspection is commonly use when legal or health issue are a concern.
-
In addition to the Level 1 Assessment we use testing and or monitoring equipment.
-
The air samples are analyzed by a third party and are used to confirm or deny hypothesis created during the assessment.
-
A moisture meter is used to determine if there are water leaks.
-
Blower doors are used to pressurize the building which then determines how tight it is. Infrared cameras show temperature differences.
-
Infrared cameras are fantastic at showing where insulation is missing in walls and if water or air leaks are present.

Common IAQ Tests:
Testing Methods:
-
Dust Collection: provides a historical view or can be used to show effectiveness of the remediation. It’s common to find mold spores, pollen, insect parts, skin fragments, dust mites, cockroach and cat allergens in dust.
-
Swab Analysis: Swabbing a surface is an effective way to sample surfaces for mold, bacteria and lead.
-
Tape Lift Analysis: Tape lifts are also good for surface sampling. The exception from a swab sample is the microbes sampled cannot be transferred to a Petri dish for growing.
-
Air Sampling: Air samples are can be utilized to evaluate indoor environments for a variety of potential contaminants including mold and bacteria.
-
Monitoring: Our air monitors can be placed in your building which record data during the day and download at night for viewing on our website the next day. The monitors can detect temperature, humidity, Carbon Monoxide and Dioxide, VOC and particulates’. This provides a wealth of information about how your building is performing when occupied.
