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.

However, it is of practical interest to compare the outdoor air measured values, to those measured indoors on the same date. Text Note ABC Towers\Outdoors 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 (CO2) 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.

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. ABC Towers / 2nd Floor / 123 Trading Co / Location Date Time CO2 Value Comment Outdoor Air 9/29/2006 to

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. Government and Industry Guidelines 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 ABC Towers / 2nd Floor / XYZ Consulting Co / Location Date Time CO Value Comment Outdoor Air 9/29/2006 to

ABC Towers / 2nd Floor / XYZ Consulting Co /ExecOffice 3 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).

ABC Co\2nd Floor\Exec Office 3\XYZ Consulting Co: GrayWolf Monitor Location Comments: The DirectSense IQ-410 probe was set up on a tripod, with sensors in the “occupied zone”. Data-logging commenced at 9:00 am, before occupants arrived, and continued through to 5:00 pm, after occupants had left.

Comments: 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. Graph styles may be predefined, or may be custom modified for each specific report. Choose from multi-Y graphs or strip graphs. Optionally auto-include event note x axis lines (date stamped text notes collected in-situ, as shown in this example). Y axis “alarm” lines may also be added to indicate government and industry maximum (and/or minimum) levels for each parameter.

ABC Towers / 2nd Floor / XYZ Consulting Co /ExecOffice 1: Water stained sill




ABC Towers / 2nd Floor / XYZ Consulting Co /ExecOffice 1: Blocked Diffuser 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 This is an example of one of the 18 Word Field Forms that come standard with WolfSense PC, which may easily 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.
