Indoor Environmental Quality

Since 1980, Healthy Buildings has developed vast experience and a deep specialization in the field of indoor environmental risk management, indoor environmental quality, and tenant retention for commercial properties.

The Benefits of a Healthy Buildings IEQ Program are:

Development of a corporate indoor environmental quality policy results in a peerless tenant retention tool. Studies show that building users value indoor environmental quality over virtually any other environmental or sustainability amenity offered in the workplace.

Healthy Buildings’ proactive and reactive IEQ Programs demonstrate an impressive “rolling due diligence” program intended to provide a formidable defense should any tenant or third party question our clients’ commitment to a safe and healthy workplace. Clients who “manage what they measure” have far lower exposure to liability than those who only address issues when they cause harm, real or perceived.

Healthy Buildings’ IEQ programs document improvements made over time. This results in a smooth due diligence process at sale. The cost of addressing IEQ is more than recovered at sale time when the documents demonstrate a high and improving standard of IEQ over the seller’s hold time. The program is part of an investment strategy for the building consistent with Healthy Buildings’ purpose – “We make buildings more valuable.”

It has been demonstrated that IEQ is one of the most economically beneficial elements of sustainability and building operations. Studies show attention to IEQ results in a 5 to 10 percent improvement in productivity. When employee salaries are considered, no other measure has a bigger economic benefit. Healthy Buildings’ IEQ programs present a powerful marketing opportunity for leasing, and a compelling economic argument for owner occupied buildings.

Our IEQ Services Include:

The Healthy Buildings indoor environmental quality proactive monitoring program consists of a detailed investigation of the design and operating practices of a building’s air handling and distribution system. This information is integrated with data collected from comprehensive air sampling and analysis. An indoor environmental quality database is established for each building allowing an evaluation of changes in the indoor environmental quality over time.

At the time of the first inspection, Healthy Buildings AUDITAIRES™ (airborne particulate contamination sensors) are installed on the ductwork. These become a focal point of Healthy Buildings’ continuing tracking and monitoring process for indoor environmental quality. The ongoing monitoring involves repeat inspections at prearranged intervals, usually annually or biannually. Analytical results from the initial indoor environmental quality inspections and subsequent reinspections are then compared with a composite database of thousands of major buildings.

The key to a successful indoor environmental quality proactive program is that the results of implementing changes can be quantified. Conversely, in the event of adverse trends in environmental quality over time, modifications can be made to correct the situation before complaints arise from the building’s occupants.

There are roughly 8,000 to 18,000 cases of Legionnaires’ Disease yearly, with the majority of those incidences occurring in commercial buildings water systems, most often found in cooling towers. A new standard published by ASHRAE alters the way buildings are managed and operated.

ASHRAE Standard 188 specifically covers risk management for building water systems as it relates to Legionnaires’ Disease. As the new published Standard of Care, building owners who document compliance with this standard will significantly reduce their liability compared with those who do not.

According to ASHRAE, the “ANSI/ASHRAE Standard 188-2015, Legionellosis: Risk Management for Building Water Systems, is intended for use by owners and managers of human-occupied buildings and those involved in the design, construction, installation, commissioning, operation, maintenance and service of centralized building water systems and components”.

Environmental concerns over the last couple of decades have come to play a major role in commercial real estate development and management. Over the last five to ten years greater emphasis has been placed upon mold and indoor environmental quality (IEQ) than perhaps any other environmental issue. Among IEQ issues, concern about toxic mold has risen to present such a liability and perception concern that forward-thinking real estate property managers routinely have their buildings inspected as part of a Proactive IEQ Monitoring Program. In California, California’s Toxic Mold Prevention Act multiplies building owners’ concerns about this issue, since it formally establishes mold as a substandard condition that should be disclosed during a real estate transaction.

Due to the numerous incidences of flooding reported throughout the country these last few years coupled with the increasing concerns about mold contamination in buildings, we thought it appropriate to have these guidelines for property managers. Note these are general guidelines that may need to be modified for specific circumstances and they may not be appropriate for all conditions.

Floodwaters do colossal damage to property. Wood swells and rots, wallboard can disintegrate and most paper items are destroyed. The mud, soil, insects, small animals and refuse carried in by the water penetrate everything. The disposal of carpets, fabrics, furnishings, wallboard and wood sections, plus the cleanup and repainting costs are usually covered by flood insurance — if the property owners are lucky enough to have such coverage.

What will not be covered by insurance are many of the long-term problems that manifest themselves weeks, months or years after the floods have receded. At the top of the list of future problems are those due to the ubiquitous molds. Molds and mildew grow on virtually anything and their multiplication and spread is prompted by dampness. Once well established in a property, they are difficult to eradicate. Spores from these fungi are minute and are light enough to be carried on air currents throughout the property. They may well settle on surfaces and remain in a dormant state for months or even years. Then, when conditions are right — perhaps simply an increase in a room’s relative humidity, new colonies germinate and re-infest the whole property again.

Scientific evaluation of all the available human data provides no evidence for a “safe” level of asbestos exposure, thus any quantity should be considered potentially dangerous. However, a health risk exists solely when asbestos fibers are released into the air and when that contaminated air is inhaled into the lungs. Even then it appears that most people exposed to relatively small amounts of asbestos do not develop problems. The fact remains, however, that the chances of developing serious respiratory illnesses, including lung cancer, are greater in those exposed to airborne asbestos fibers.

Conversely, this correctly confers that many asbestos bearing materials or products are of no health risk whatsoever when used in the normal course of events. However, any level of asbestos containing materials inside a building constitutes a hazard. It should be noted that hazard is a potential for harm, whereas risk is the probability that this potential may become actual. With this distinction, it is self-evident that a simple identification and analysis of asbestos containing materials (ACMs) is insufficient to gauge the degree of risk. Since it is the airborne fraction of asbestos that is dangerous, a major factor in assessing risk conditions is to have a knowledge and understanding of the design of the building in general and its air handling system in particular. Thus, all Healthy Buildings building surveys include a review of the ventilation system layout and operation.

Indoor Environmental Quality Additional Testing Available

The following is a listing of additional field tests and samples that Healthy Buildings often perform during indoor environmental quality inspections and are available to our clients on an as needed basis. Note: these are just some of the more common tests and samples conducted in commercial buildings; Healthy Buildings can meet client sampling needs for any situation based on the unique field characteristics at hand.

Airborne Particulates

Airborne particulates are measured using a portable Ultrafine Particle Counter. This highly sensitive device is capable of measuring nanoparticles or particles less than one micrometer (um) in diameter using a precision laser and nucleated isopropyl alcohol. This diagnostic tool is particularly suited to indoor environmental investigations involving boiler leaks, vehicle exhaust odors, photocopy/toner emissions, cooking odors, and complaint investigations where standard airborne dust and particle monitoring are insufficient.

Airborne Mold Constituents

For airborne mold spores, fungal fragments, and potentially allergenic particle sampling, Healthy Buildings uses a non-viable spore trap, such as the AirOCell (AOC) cassette and pump. The AOC device allows for the rapid collection of a wide range of airborne aerosols including mold spores, pollen, insect debris, fibers, and inorganic particulate. This sampling method, as opposed to the culture collection method, brings several significant advantages: 1) it is more cost effective; 2) it allows for a rapid turnaround on results; 3) the method is subject to less contamination than culture methods; and 4) samples can be collected unobtrusively (ideal for office environments). Samples are subsequently analyzed using optical microscopy methods.

Surface Mold

Microbial surface samples are taken total using sterile multi-organism detection swabs and/or surface imprints. The swab samples are incubated and subsequently analyzed for bacterial and fungal types present with species identification using optical microscopy techniques. The surface imprint samples are taken for quick identification of toxic mold spores.

Lead and Copper in Drinking Water

Lead and copper in drinking water analysis is achieved by collecting water samples using special acid-washed bottles with subsequent analysis using atomic absorption spectrometry for lead content. The results will be reported in micrograms per liter (ug/L) and compared with current EPA standards for drinking water in commercial buildings.

Watercheck (Comprehensive Drinking Water Screening)

Watercheck (drinking water) samples are collected in a series of five sterilized and acid washed containers. Within 24 hours, the samples are sent to our laboratory for analysis. Ten physical characteristics are examined using electrogravimetric and nephelometric techniques. Fifteen inorganic metals are screened using ion chromatography. Forty-eight organic compounds are tested for using gas chromatography and coliform bacteria, including e. coli, are assessed using a membrane filtration technique. All results are compared to the Maximum Contaminant Levels (MCLs) as regulated by the Environmental Protection Agency and other government agencies.

Legionella

Legionella bacteria sampling & analysis will is accomplished by drawing 100-1,000 milliliter water samples from cooling towers or other suspect building water sources. Samples are transferred using two-stage inoculation onto a selective buffered charcoal yeast extract. The extract is then incubated for a minimum of ten days, after which it will be analyzed for legionella bacteria and counted using a laboratory stereoscope. Samples are reported in colony forming units per milliliter of water (CFU/ml) and compared to OSHA guidelines.

Air Handling Unit(s) Inspection

Air handing units are inspected for factors relating to ventilation, filtration, and hygiene. Specific issues include, but are not limited to: control system, damper settings, integrity of internal insulation, proper drainage of water, integrity and cleanliness of AHU internals, filter fit and condition, and rating of filtration systems with respect to indoor environmental quality parameters.

Volatile Organic Compounds – Full Spectrum Identification

Full spectrum volatile organic compound (VOC) samples are collected. These samples shall be taken by passing known volumes of air through mulit-bed Sorbent Tubes. The samples will be analyzed by capillary gas chromatography and mass spectroscopy. The compounds collected include alcohols, benzene, toluene, ethylbenzene, and xylene. The results will be analyzed with respect to relevant maximum recommended standards and guidelines for commercial indoor environments.

Formaldehyde

For formaldehyde measurements Healthy Buildings uses electronic detectors capable of sensor resolutions at 0.01 ppm with detection limits of 0.01 ppm (10 ppb). The unit uses a standards generator to compare permeation rates of formaldehyde gas on a bed of activated carbon. Results fall within the tolerances of NIOSH method 3500. The sensor is calibrated daily and factory calibrated annually.

Datalogging – Carbon Dioxide, Carbon Monoxide, Temperature, Relative Humidity

Continuous monitoring over a multiple day period for carbon dioxide, carbon monoxide, temperature, and relative humidity using an electronic Datalogger in conjunction with non-dispersive infrared and electrochemical sensors.

Miscellaneous Gases (nitrogen dioxide, sulfur dioxide, and hydrogen sulfide)

Miscellaneous gases are monitored directly using electrochemical sensors. These sensors are zeroed with hydrocarbon free air and spanned to appropriate low level concentrations using NIST certified primary standard gases purchased from Air Liquide (Cambridge, MD). Sensor resolutions are listed at 0.04, 0.01 and 0.10 ppm respectively. In-house calibrations are performed monthly. Factory calibrations are performed annually.

Electromagnetic Force (EMF) Screening

The screening process for EMF covers Extremely low frequency (ELF) and very low frequency (VLF) radiation. Measurements will be made using appropriate Walker Scientific EMF Power Survey Meters in three probe directions to arrive at a Root Mean Square (RMS) average. The measurements will be taken within the building as close as possible to the most likely source locations (e.g., power cable feeders, transformers, main switching rooms, etc.), as well as in the regularly occupied spaces nearest to those sources. This will give a fair indication of the levels of exposure at the most “suspect” sites within the building.

Due Diligence Inspections – Property Condition Assessments

Healthy Buildings is frequently retained by building purchasers to review buildings during the due diligence period. Some or all of the above services can be included in these inspections.

I want to take a few minutes to let you know how impressed I was with the professionalism of your technician. If he hadn’t introduced himself we would not have known he was on the property. This was my first experience with Healthy Buildings and was very pleased with how comprehensive and informative your report was. Having been at the building since August of 2011 the building was a complete stranger to me and knew that I had an uphill battle in learning the building. Your report provided me with a wealth of information on what kind of shape my mechanical equipment was in and how well it has been maintained as well as identifying the problem areas. A job very well done. Your staff did you and themselves proud.

Legionella Testing & Risk Assessment

For control of Legionella bacteria in water systems, it is highly advisable to identify and assess the risk of exposure to legionella bacteria from work activities and water systems in the building. Any workplace with water services should have a risk assessment conducted periodically.

Legionella Risk Assessments should be reviewed on a regular basis and a new assessment should be considered if any of the following apply:

  • It is more than two years since the last risk assessment
  • There have been changes to the water systems
  • The building use has changed
  • There is new information about risks or control measures
  • Checks indicate that control measures are no longer effective
  • A case of Legionnaires’ disease/legionellosis is associated with the system.

Features:

Our Legionella Testing and Risk Assessment service may include some or all of the following:

  • Production of a list of water services plant and outlets.
  • Inspection of plant to assess condition and compliance with Approved Codes of Practice
  • Production of water system schematics.
  • Samples for the presence of legionella bacteria from various locations within the down service water systems e.g. showers, taps etc or from evaporative cooling systems.
  • Samples for microbial analysis, using dip slides, from various locations within the down service water systems e.g. showers, taps, tanks etc or from evaporative cooling systems.
  • Temperature measurements will be taken from various locations within the down service water systems e.g. showers, taps, tanks etc or from evaporative cooling systems.
  • pH measurements will be taken from various locations within the down service water systems e.g. showers, taps, tanks etc or from evaporative cooling systems.
  • Measurement of conductivity from evaporative cooling systems.
  • Identification of sources of risk.
  • Numerical assessment of level of risk at the sources identified using HBI’s unique algorithm.
  • Review of the existing System of Legionella Control to assess compliance with regulations where applicable.
  • Creation of System of Legionella Control on Records for Buildings, Healthy Buildings’s web-based management system.

Legionella Background

In July, 1976 in Philadelphia an outbreak of pneumonia affected 221 people, killing 34. Many were members of the American Legion attending a convention in the Bellevue-Stratford Hotel. The causative organism, Legionella pneumophila, is widely distributed in nature and although positively identified and named only several months after the outbreak of the illness that gave the disease its name, legionnaires’ disease, it has probably been causing infections in humans for hundreds of years.

There are now identified more than 30 species of legionella and at least 14 serogroups of Legionella pneumophila, however the Pontiac sub-type (MAb2) of Legionella pneumophila Serogroup One is responsible for more than 90% of known infections. In recent years up to several thousand cases of legionnaires’ disease are reported each year in the United States by the CDC alone.

Habitat

Legionella species occur naturally in soil, rivers and lakes and have the ability to successfully colonize man-made water handling and storage systems, which often provide ideal conditions of nutrition and temperature for their proliferation. Legionella infection is not transmissible from person to person; it is caused by the inhalation of water aerosols containing the bacteria by susceptible individuals. The numbers of organisms required to induce infection is not known but will vary according to age, general health and other predisposing factors.

The potential for legionella to become a hazard to the health of large numbers of people is greatly enhanced by conventional water and air conditioning engineering methods as used in re-circulating cooling towers, air conditioning chill coils and humidifiers, water storage and distribution systems and other aquatic systems such as whirlpool spa baths.

Cooling Towers and Water Storage Systems

The single isolation of these bacteria from a water system does not mean that the disease will necessarily manifest itself but if the contaminated water becomes an aerosol the risk of human infection is greatly increased. Thus if man-made water systems produce jets, sprays or mists, as with cooling towers, showers and some types of humidifiers, it is important to minimize the chances of legionella colonizing the water reservoirs, storage tanks and other aquatic systems serving them. Certainly cooling towers are of particular importance for their operating temperatures are at an optimum level, they are designed to aerosolize the water and they are easily and frequently contaminated by wind-blown dusts and soil particles which can carry with them disease producing micro-organisms including legionella.

The presence of these bacteria in water systems is therefore of prime importance to engineers, building managers and hygienists. The organisms can be controlled in such systems by the application of biocides and their detection and identification plays a vital role both in initial assessment of the water system and subsequent treatment effectiveness and ongoing water quality monitoring.

Identification and Assessment of Risk

At the time of water sampling Healthy Buildings Field Technicians evaluate all the relevant factors affecting the condition of the water source, such as, system design, accessibility to airborne contamination, exposure to light, circulation rate, pH, temperature, droplet formation, water treatment program, etc.

Testing the sample will then identify if the source is safe or contaminated at the time of sampling. Assessment of the hazards then permits high-risk sources to be identified and ensures that responsible means of implementing precautions are undertaken.

As the likelihood of future contamination can be predicted this also allows maintenance regimes and water treatment protocols to be established on the basis of need rather than on guesswork.

Regular Monitoring

The Healthy Buildings sampling protocol is designed to ensure accuracy, avoid ambiguity, and protect client confidentiality and to aid in diagnosis of contaminated water systems.

Water from cooling towers, spray-type humidifiers and other air conditioning associated equipment present the greatest degree of risk and a routine sampling procedure from their water storage reservoirs and from other water systems can be set up. This allows management to have up-to-date reports on the status of their building water systems and gives confidence that maintenance standards are being met. Tenants, staff and building users can then be assured that all reasonable precautions are being taken to avoid the spread of Legionnaires disease.

Furthermore, immediately prior to routine cleaning and maintenance, cooling towers and humidifiers can be tested for the presence of legionella. If it is found to be present then the necessary water treatment can be done, quickly verified for its effectiveness and engineering staff assured that they will not be exposed to microbial hazards as they carry out the work. Hot and cold water services and other water systems can similarly be appraised for risk and a suitable system of maintenance, cleaning and testing implemented.

Because of its widespread presence in nature and its ability to thrive in man made water systems it is unlikely that legionella can be completely or permanently eradicated from these potentially hazardous systems. However, by suitable design, maintenance, treatment and testing of building water systems it is possible to control the conditions which allow this and other bacteria, fungi and protozoans to multiply, thus keeping the incidence of disease outbreaks associated with such systems at a minimum. Any Proactive Monitoring System applied to buildings and their water systems should therefore include regular monitoring for the presence of legionella at appropriate outlets.

The increased public awareness environmental health issues and the acceptance of the legislation now approved have ensured that risk assessment and appropriate preventative maintenance steps, should now be considered as the norm for every building.
