Site Background

ABC Towers, located at 112 Main Street, Rowayton, CT is a multi-use building, offering retail
space on the 1st floor, white collar office space and residential apartments on the above ground
floors. The building is 8 stories, with 139,500 square feet of total floor space.

Several complaints have been received by occupants on the 2nd floor

Site notes collected in situ:

ABC Towers appears, upon initial impression, to be a well-maintained facility. Our plan is to
take snapshot samples from one or two representative areas on those floors other than the 2nd
floor from where complaints have emanated. We’ll then take snapshot readings from numerous
locations on the 2nd floor, and trend log, for the course of a work day, the 2 locations where the
complaints have arisen.

Survey Strategy

A walk-through site inspection of several occupied spaces on the 2nd floor, plus a few
representative spaces on other floors has been initiated. In-situ spot testing has been logged at
each of these spaces utilizing the equipment detailed at the end of this report. Datalog trending
was initiated at the 2 locations that have been the main source areas for complaints. In addition,
air samples were collected at the locations indicated in this report. These samples were sent to
XYZ Laboratories for laboratory analysis. The results of these laboratory tests, including details
of the equipment and methodology employed, are attached at the end of this report.

A “primary” site/location may be selected for each specific report. This site will be first up in the report.
It’s the location that general notes (text, drawing, photo, custom, event or Word template) related to the
over-all site, collected in the field, will have been attached to.

Outdoor air conditions will change over the course of the day, and the above figures represent a
“snapshot’ of the outdoor conditions at the time that the readings were recorded. However, it is
of practical interest to compare the outdoor air measured values, to those measured indoors on
the same date.

Text Note
ABC TowersOutdoors

Main Street is a somewhat busy road, with moderate traffic in the morning, at the time the
outdoor values were measured. This was a sunny day with light winds. Measurements were
taken in front of the building’s lobby entrance, just off the road.

WS Advanced Report Generator searches for any locations with “out” at the beginning the name, and
automatically inserts data and notes associated with them at the position in each report where you’ve
selected for OUTDOOR MEASUREMENT INFO to appear.



Carbon Dioxide (CO 2 )
Why Measure this Parameter?

CO2 is very rarely a pollutant of direct health concern, itself! Rather, because building
occupants exhale CO2, it is used as a tracer gas that is an excellent indicator of adequate (or
inadequate) ventilation. Low CO2 concentration implies that human generated pollutants are
being properly diluted. And, in absence of a specific pollutant source, it is a rough estimator that
the thousands of potential building generated pollutants are being dispersed. This makes it a
key indoor air quality indicator.

CO2 will generally only be of concern as a toxic gas itself in industrial processes where bottled
CO2 gas is utilized, such as breweries, or when there is an inadequately ventilated combustion
process (where the other combustion gases will usually be of greater concern).

Typical Background Levels

Outdoor CO2 levels are usually around 350ppm (although they may often be 100-200ppm
higher in urban areas).

The text above (and for Government and Industry Guidelines below) is auto-inserted, based on
WolfSense Sensor tips. This information may be edited for all, or for individual reports.

Government and Industry Guidelines

US OSHA Technical Manual (section iii, chapter 2), 1999, states that 1,000 ppm CO2 should be
used as an upper limit for indoor levels, as a guideline for occupant comfort.

US OSHA Standard Number: 1910.1000 TABLE Z-1 Limits for Air Contaminants Permissible
Exposure Level (PEL) for workers: 5000ppm; 9000 mg/m3 for an 8 hour Time Weighted
Average (TWA). It is of note that OSHA has published intentions to raise the 8 hour CO2 TWA
to 10,000ppm, but this change is yet to be approved.

NIOSH 1992 REL (Recommended Exposure Limit): TWA 5000 ppm (9000 mg/m3) STEL (Short
Term Exposure Limit) 30,000 ppm (54,000 mg/m3)

ACGIH 2005 TLVs & BEIs: 5000ppm 8 hour TWA, 30,000ppm STEL

ASHRAE Standard 62.1-2004 suggests maintaining a steady-state CO2 concentration in a
space no greater than about 700 ppm above outdoor air levels to remove human generated
pollutants. Additional ventilation may be needed to dilute building generated pollutants.

ASHRAE Standard 62.1-2004 defines adequate ventilation for specific use designed spaces.
For example, 17 cfm/person of dilution air is suggested for office spaces, which roughly
translates to a CO2 concentration of about 600 ppm above outdoor air levels.



OSHA 1994 proposed Indoor Air Quality Rules: “If the indoor sample results show levels that
are greater than 800 ppm or that the indoor levels are significantly more than the outdoor
levels, initiate actions to investigate the functioning of the HVAC system and determine if the
employees are affected”. Note that the proposed 1994 IAQ rules have not been adopted by
OSHA.

Comments:

CO2 measurements recorded during snap-shot logs indicate that all readings in this area are
below or well below OSHA and ASHRAE guidelines. However, the trend logging at location
/Exec Office 3 indicates that CO2 exceeds each of these recommendations in the late morning
and late afternoon. We recommend that the air handling system be set to provide a greater
volume of Outdoor Air (dilution air) from 8:00 am through 4:00 pm. OA air s/b increased from
35% of supply air, up to 50% during that period.

Comments:

CO2 measurements recorded during snap-shot logs indicate that all readings in this area are
below or well below OSHA and ASHRAE guidelines, except in the /Conference Room. We
recommend logging CO2 over the course of a typical high occupancy period to confirm that the
CO2 levels are elevated. If elevated CO2 levels are confirmed, a demand control strategy,
utilizing a fixed CO2 sensor might be considered to resolve the inadequate ventilation for
periods of high occupancy. Alternatively, a simple manual ventilation control may be sufficient
to provide enough outdoor dilution air during the temporary, high occupancy periods.



Carbon Monoxide (CO)
Why Measure this Parameter?

Carbon monoxide (CO) is a poisonous, colorless, odorless, and tasteless gas. Although it
has no detectable odor. CO is a common industrial hazard resulting from the incomplete
burning of natural gas and any other material containing carbon such as gasoline, kerosene, oil,
propane, coal, or wood.

Typical Background Levels
Average levels in homes without gas stoves vary from 0.5 to 5 parts per million (ppm). Levels
near properly adjusted gas stoves are often 5 to 15 ppm and those near poorly adjusted stoves
may be 30 ppm or higher.

Sources of Carbon Monoxide
Elevated CO may be present in any type of space for a number of reasons: most commonly
due to inappropriately exhausted combustion processes.
Unvented kerosene and gas space heaters; leaking chimneys and furnaces; back-drafting from
furnaces, gas water heaters, wood stoves, and fireplaces; gas stoves; generators and other
gasoline powered equipment; automobile exhaust from attached garages; and tobacco smoke.
Incomplete oxidation during combustion in gas ranges and unvented gas or kerosene heaters
may cause high concentrations of CO in indoor air. Worn or poorly adjusted and maintained
combustion devices (e.g., boilers, furnaces) can be significant sources, or if the flue is
improperly sized, blocked, disconnected, or is leaking. Auto, truck, or bus exhaust from
attached garages, nearby roads, or parking areas can also be a source.

Health Effects Associated with Carbon Monoxide
At low concentrations, fatigue in healthy people and chest pain in people with heart disease. At
higher concentrations, impaired vision and coordination; headaches; dizziness; confusion;
nausea. Can cause flu-like symptoms that clear up after leaving home. Fatal at very high
concentrations. Acute effects are due to the formation of carboxyhemoglobin in the blood,
which inhibits oxygen intake. At moderate concentrations, angina, impaired vision, and reduced
brain function may result. At higher concentrations, CO exposure can be fatal.


The current Occupational Safety and Health Administration (OSHA) Permissible Exposure Limit
(PEL) for carbon monoxide is 50 parts per million (ppm) parts of air (55 milligrams per cubic
meter (mg/m(3))) as an 8-hour time-weighted average (TWA) concentration [29 CFR 1910.1000
Table Z-1].

The National Institute for Occupational Safety and Health (NIOSH) has established a
recommended exposure limit (REL) for carbon monoxide of 35 ppm (40 mg/m(3)) as an 8-hour
TWA and 200 ppm (229 mg/m(3)) as a ceiling [NIOSH 1992].


ACGIH 2005 TLVs and BEIs ; 25ppm (8 hour TWA).

ASHRAE Standard 62.1-2004 references US OSHA, NIOSH and ACGIH values. However,
ASHRAE suggests that consideration must be taken that those values have been established
for healthy workers. For indoor environments, where occupants may not be of excellent health,
may be exposed to more than 8 hours per day, and may not be expecting any type of toxic
exposure, exposures should always be lower than the worker exposure levels.

The U.S. EPA National Ambient Air Quality Standards, 1990, for outdoor air are 9 ppm (10
mg/m3) for 8 hours, and 35 ppm (40 mg/m3) for 1 hour.

The World Health Organization’s guidelines for carbon monoxide exposure (1987):
100 mg/m3 (90 ppm) for 15 min
60 mg/m3 (54 ppm) for 30 min
30 mg/m3 (27 ppm) for 1 h
10 mg/m3 (9 ppm) for 8 h

Notes, collected on-site:

There have been complaints from the primary occupant of this office, a high level executive,
over the past few months of “stuffiness” and “smells”. This office was partitioned 4 months ago,
roughly half of the space of Executive Office 2, which was divided into 2 parts. There are 3
diffusers in that half of the office, and just one on this partition. There also is a roof leak in the
NW corner, which leaks when there is heavy rain. There is visible evidence of staining and mold
growth. Samples have been collected to send out to XYZ Laboratories for cultures. Results are
attached (pages 113-115).

Although the air handling system was not designed for the requirements of this office, the way
that it has now been partitioned, the CO2 levels tested indicate adequate ventilation to remove
occupant generated pollutants, as long as the door to the general office remains open.

Notes, collected on-site:

There is obvious leaking from the ceiling onto one window sill. We’ve measured 28.5% moisture
at that spot with our Protimeter moisture meter. The diffuser directly above the executive’s desk
has been taped over. According to the occupant of this office, there is “too much of a draft when
the air handling system kicks on”. CO2 levels were a bit elevated at the time of the test.

Data, graphs, photos, notes for other specific locations are all auto-included.



Occupant Interview

File Number 09290511
Building Name ABC Towers
Address 112 Main St, Norwalk, CT
Occupant Name Susan Mays
Work Location XYZ Consulting Co, 2nd Floor

Completed by Jim Small
Title IAQ Inspector
Date September 29,2006

Sections 4 discusses collecting and interpreting information from occupants.

SYMPTOM PATTERNS
What kind of symptoms or discomfort are you experiencing? Headaches, itching eyes, sometimes nausea

Are you aware of other people with similar symptoms or concerns? Yes X No

If so, what are their names and locations? Beth Romero, who sits just outside of executive office 3.

Do you have any health conditions that may make you particularly susceptible to environmental
problems? (Please 'x' all that apply)
X contact lenses chronic cardiovascular disease
allergies chronic respiratory disease
chronic neurological problems undergoing chemotherapy or radiation therapy
immune system suppressed by disease or other causes

TIMING PATTERNS
When did your symptoms start? About 6 months ago
When are they generally worst? Mid to late afternoon
Do they go away? If so, when? Yes, shortly after leaving the building
Have you noticed any other events (such as weather events, temperature or humidity changes, or
activities in the building) that
tend to occur around the same time as your symptoms? No

SPATIAL PATTERNS
Where are you when you experience symptoms or discomfort? Executive Office
Where do you spend most of your time in the building? Executive Office

ADDITIONAL INFORMATION
Do you have any observations about building conditions that might need attention or might help explain
your symptoms (e.g.,
temperature, humidity, drafts, stagnant air, odors)? The temperature gets high in the summer and there
seem to be odors "like plastic" at times. It might have something to do with the new printer in the office.

Have you sought medical attention for your symptoms? Yes

Do you have any other comments? No

be completed on the mobile PC on site. End-users may modify and/or eliminate any of these 18 templates and/or
create their own Field Forms.



General Conclusions, Recommendations

Additional Testing Suggested:

The outdoor air (dilution) ventilation rate is appropriate for all spaces measured, with the
exception of Executive Office 1 at XYZ Consulting. Trend logging of CO2 is recommended for
that space, after removal of the cardboard blockage and installation of a diffuser grille that
reduces direct airflow on the occupant’s desk in this space..

Ozone at xxx has tested above the EPA Outdoor recommended levels of xxx. Trend logging of
O3 is recommended for xxx space to determine maximum exposure over the course of the 8
hour work day. As this space contains a large copier machine, during the course of trend
logging the copier should be run for some time and turned off for some time. If the copier
machine is identified by additional testing as the source of elevated O3, etc, etc.

This “Category” is an example of “prompted text”. GrayWolf provides several example text bocks for the
Conclusions & Recommendations section. Edit them, and/or create your own (short or extensive) list of
text blocks. When you generate individual reports, you will be prompted to select the text block(s) to
include for this category, and for any other “prompted text” category. You may then edit the text block(s)
that you selected; customized to the specific survey, once the draft Word report is generated.



Instrumentation, Methodology

Testing was performed with the following equipment (calibration data for this instrumentation
