Bring Purified, Fresh Air Into Your Home

The patent pending Filtered Fresh Air Ventilation System (FFAVS) for residential buildings delivers filtered outside air into the home for ventilation.

Tight homes need ventilation and all outside air should first be filtered to remove smog, ozone, radon, pollen, mold spore, viruses, and landscape chemicals.

Most homes get there “fresh air” from the crawlspace, or through back drafting, or leaks in the thermal envelope (walls, windows etc).

The FFAVS provides ventilation, dilution and pressurization, which reduces the levels of pollutants and dust in your home.

Even slightly altering the pressurization of a building inhibits air infiltration of pollutants such as pollen, mold, and seasonal allergens through common penetration points such as door and window seals, chimneys, bathroom exhaust, clothes dryers, stove exhaust, and moist moldy air from the crawlspace.

Attic and Radiant Barrier Insulation

2010-04-12T22:33:00.000-07:00

Attics...Cooler, Cleaner and Energy Efficiency

Radiant barriers installed over fiberglass insulation or installed on roof decks make attics cooler, cleaner and more energy efficient.

Radiant barriers were developed by NASA and perform as reflective insulation. Utilizing lightweight aluminum, radiant barriers reflex 97% of the sun’s energy. Much of the heat entering your home comes through the roof and attic.

Adding a radiant barrier in the attic helps to keep your house cooler in the summer and warmer in the winter. Radiant barrier installed over fiber floor insulation dramatically enhances R-value of the fiber insulation and keep it clean. Radiant barrier covers are also used on the attic ladder, recessed lamps, and air ducts.

Hot Dirty Attics Waste Energy and Affect your Air Quality

Attics can get over 130°, and pollen, mold, insects and rodent and bat droppings contaminate the fiberglass insulation. Hot contaminated air from the attic enters the living area through the electrical, plumbing and air duct holes. Attic pull down ladders, access panels and walk in doors allow conditioned air to enter the attic.

Attic fiber insulation needs to be evenly applied with no gaps, or voids. Covering fiber insulation with a radiant barrier greatly increases its efficiency.

Radiant barrier can be installed on the roof decking, which may reduce attic temperatures up to 30°.

Radiant barriers may be used to create an inexpensive attic storage area.

Tax credits are available for attic insulation. A 30% tax credit with a $1,500 maximum is allowed on 2009 and 2010 tax returns.

Air Duct Cleaning

2010-04-12T22:31:00.000-07:00

Mold growth is commonly found in the air ducts, along with construction debris, drywall dust, pollen, skin flakes, fiberglass, and insects. Every time the central air system comes on to heat or cool some of these pollutants are “puffed” into the air you breath.

The EPA states: “health effects may show up either years after exposure has occurred or only after long or repeated periods of exposure”.

“These effects, which include some respiratory diseases, heart disease, and cancer, can be severely debilitating or fatal. It is prudent to try to improve the indoor air quality in your home even if symptoms are not noticeable”.

Contaminants build up inside the air ducts over time and make your duct system an ideal breeding ground for mold. These resulting contaminants are then circulated throughout your home and affect the health and comfort of your family.

Homes older than 2 years may have air ducts that leak.

The air distribution system or air ducts should be very clean, air tight, no mold growth and use high efficiency air filters.

Mold contaminated ductliner is common in air ducts that leak. This situation can be hazardous to your health.

Leaky air ducts in the crawlspace or attic draw in polluted air with mold, pollen, fiberglass, insects, smog, ozone and radon.

Typically air ducts are internally lined with insulation called “ductliner”. The ductliner is made of thick fiberglass which is an excellent surface for growing mold if wet or moist.

Mold can be allergenic, pathogenic (creates a disease) and or toxic, so fixing the cause of the moisture that allows it to grow and removing the mold is critical to having a healthy building.

Indoor Environmental Systems (IES) cleans both residential and commercial air ducts. IES has the equipment and technical knowledge to clean your air ducts to the National Air Duct Cleaning Associations and the Environmental Protection Agency standards. IES takes before and after pictures. Air samples and 24hr monitoring is also available to verify air duct cleaning effectiveness and provide through IAQ assessments.

Key benefits to air duct cleaning:

Better Efficiency - Average residence saves $5 to $25 per month.

Increased Comfort - Houses smell better, heat and cool quicker.

Improved Air Quality - Reduces dust, pollen, and mold levels.

Better Health – Those with allergies, asthmas, heart disease, and cancers benefit from good air quality.

Air Sealing

2010-04-12T22:29:00.000-07:00

A “leaky" building allows conditioned air to leave the building which causes higher energy bills and allows contaminants and moisture to enter the building. Because heat rises air leaks out of the top half of the building and is drawn in from the lower half. This driving force is called “stack affect”.

When the “top” of the building or the attic floor is sealed the stack effect, which is the driving force for air leakage is stopped.

IES, Inc can determine the best strategy to reduce air leakage and improve indoor air quality. Using hi-tech expanding insulation foam we fill gaps, voids and cracks in the building envelope.

With specific gaskets we seal air leakage from doors, windows, and fireplaces. Also, sealing the air ducts makes your heating and air conditioning system more efficient and your home more comfortable.

Tight buildings need controlled ventilation, which is supplied by the patent pending Filtered Fresh Air Ventilation Systems attached to your heating and air conditioning system.

Air sealing a house or commercial building increases comfort by reducing the drafts and the amount of humidity that enters will also be reduced, which is a big factor in the health, comfort levels and durability of the building.

Assessments: Air, Mold, Water, Solar

2010-04-12T22:27:00.000-07:00

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:

Mold
Lead
Radon
Humidity
Bacterial
Dust Mites
Ventilation
Particulates
Pressure Differentials
Carbon Monoxide & Dioxide
Allergens
Dust Characteristics

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.
