4 Lincoln School Limited IAQ Services February INTRODUCTION Based upon your acceptance of AETHER Proposal 15009R, AETHER conducted limited IAQ testing within the school facility on February 17, AETHER understands that our services were in response to concerns that have been expressed regarding specific IAQ components within the school building. In general, AETHER conducted a limited visual assessment, as well as testing for Carbon Dioxide (CO 2 ), Carbon Monoxide, Temperature ( F), Relative Humidity (%RH), and airborne fungal spore counts in areas using the following sampling location guideline: Representative portions of student accessible corridors and common areas. Those classrooms identified by school personnel as areas with known or perceived issues, and/or those rooms identified by Siemens as locations with potential issues regarding suspect mold growth or inoperable ventilation components that could directly impact IAQ (i.e. Inoperable outdoor air intake dampers, visible suspect mold growth on filters). Approximately 20% of the remaining classrooms. For this school, AETHER was not provided with a list of rooms to include. Limitations This survey was performed using procedures and a level of diligence typically exercised by professional consultants performing similar services. The results of our testing and any conclusions apply only to those areas tested at the time the samples were collected and should not be considered comprehensive enough to represent all areas of the structure. For this reason, care should be taken to recognize individual reports of concerns within specific areas and ensure that they are addressed rather than attempting to extrapolate findings contained herein to determine the validity of the concern. In many instances, teacher and student belongings may have obscured conditions. Interpretation of analytical data is subject to change based on input from licensed medical personnel or individual health conditions, so any conclusions contained herein should not be considered to apply in all cases and may need to be re-evaluated based on individual cases/concerns. AETHER was contracted to solely address the parameters and locations discussed in this report and this report is in no way a guarantee that other hazards are not present.

5 Lincoln School Limited IAQ Services February LIMITED VISUAL ASSESSMENT Within each selected sampling area, AETHER conducted a visual assessment. The assessment was limited to documenting visible indications of water damaged materials and/or suspect mold growth on exposed surfaces (ceiling tiles, walls, ventilation components). In addition, AETHER documented readily apparent observations of conditions that could have likely impacted other parameters tested for during our services. The survey did not include comprehensive building or mechanical evaluations to aid in the delineation of conditions which may be located within enclosed spaces such as, ceiling plenums, wall cavities, and internal ventilation components. The following table summarizes pertinent observations made within each sampling location: Location Outdoors Cafeteria Ground has snow cover Truncated Notes 35 people. Forced air vents visibly dusty. 3 stained ceiling tiles people. 3 plants. 2 stained ceiling tiles. Ventilator visibly clean 1 st Corridor Visibly clean an no stains in area people. 1 stained ceiling tile. Visibly clean 105 Numerous plants. Ventilator on but windows open because heat is uncontrollable plants. 1 ceiling tile with a large stain. Ventilator on but vents covered because of heat people. 16 plants. Ventilator on but covered. 1 stain ceiling tile people. 2 plants. Ventilator on but vents covered to minimize heat. Minor dust 2 nd Corridor 3 plants. Visibly clean and no stains in area people. Visibly clean and no stains in area people. 3 ceiling tiles with stains. Ventilator on but vents covered and windows open due to heat people. 6 plants. Visibly clean and no stains in area 2 nd W Corridor 2 ceiling tiles with large stains Please note that these are subjective notes. i.e. Visibly clean does not infer a complete absence of dust rather that exposed surfaces in the area appeared free of heavy or atypical accumulations of dust and debris.

6 Lincoln School Limited IAQ Services February CARBON DIOXIDE TESTING Within each selected sampling area, AETHER utilized an Extech CO250 direct-read instrument to document CO 2 concentrations at the sampling location. The instrument was pre-calibrated according to the manufacturer s recommendations. AETHER placed the instrument in a representative area within the room at a height approximately that of seated breathing level where it was allowed to stabilize for at least five (5) minutes. The stabilized readings were then recorded and have been summarized in the following graph: Carbon Dioxide Results 2nd W Corridor nd Corridor st Corridor Cafeteria 852 Outdoors Carbon Dioxide (ppm) Each of the selected sampling locations were within the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) recommendation of no more than 700 ppm greater than the outdoor concentration. This guideline is typically for comfort (perception of good air quality, body odor, etc.), and is not a ceiling value for air quality. It is important to note that although there are typically reports of increased drowsiness and perception of poor air quality in the 1,000 to 2,000 ppm range, CO 2 is not considered a contaminant or pollutant at these levels.

7 Lincoln School Limited IAQ Services February RELATIVE HUMIDITY TESTING Within each sampling area, AETHER utilized an Extech CO250 direct-read instrument to document RH levels at the sampling location. The instrument was pre-calibrated according to the manufacturer s recommendations. AETHER placed the instrument in a representative area within the room at a height approximately that of seated breathing level where it was allowed to stabilize for at least five (5) minutes. The stabilized readings were then recorded and have been summarized in the following graph: Relative Humidity Results 2nd W Corridor nd Corridor st Corridor Cafeteria 12.2 Outdoors Relative Humidity (%) The selected sampling locations fell within a range of % relative humidity. While there are no mandated lower limits for relative humidity, there is an optimum range and it is widely reported that indoor relative humidity levels below 30% can increase occupant discomfort, eye irritation, stuffy noses, aggravate allergies and potentially increase the survival and transmission of some viruses. However, in buildings where mechanical systems are not designed with humidity controls, it may not be practical to increase relative humidity so that it falls within the ideal range.

8 Lincoln School Limited IAQ Services February TEMPERATURE TESTING Within each sampling area, AETHER utilized an Extech CO250 direct-read instrument to document air temperature at the sampling location. The instrument was pre-calibrated according to the manufacturer s recommendations. AETHER placed the instrument in a representative area within the room at a height approximately that of seated breathing level where it was allowed to stabilize for at least five (5) minutes. The stabilized readings were then recorded and have been summarized in the following graph: Temperature (F) 2nd W Corridor nd Corridor st Corridor 108 Cafeteria Outdoors Temperature (F) Most of the selected areas exceeded the ASHRAE recommended temperature range of F for winter. It is important to note that although the ideal temperature range is based on occupant comfort for a majority of people and may not be suitable for everyone, the majority of personnel expressed to AETHER that they were too hot. In addition to increased occupant discomfort, higher temperatures in winter are associated with higher energy costs.

9 Lincoln School Limited IAQ Services February CARBON MONOXIDE TESTING Within each sampling area, AETHER utilized an Extech CO10 direct-read instrument to document CO levels at the sampling location. The instrument was pre-calibrated according to the manufacturer s recommendations. AETHER placed the instrument in a representative area within the room at a height approximately that of seated breathing level where it was allowed to stabilize for at least five (5) minutes. The stabilized readings were then recorded. No detectable concentrations of carbon monoxide were detected indoors during our testing services. For reference, 0-1 PPM CO is typically considered a normal background level for indoor air with 9 PPM being a maximum level for acceptable IAQ. Higher concentrations are permitted in regards to health standards.

10 Lincoln School Limited IAQ Services February FUNGAL SPORE-TRAP TESTING AETHER collected air samples from selected areas using Allergenco-D spore trap cassettes. Samples were collected using a sampling pump calibrated to a flow rate of 15 liters per minute for five (5) minutes in accordance with the manufacturer s recommendations. Following collection, the samples were shipped under chain of custody to EMSL Analytical in Cinnaminson, New Jersey and analyzed for total fungal spore count and genus identification. EMSL is accredited by the American Industrial Hygiene Association (AIHA) Environmental Microbiological Laboratory Accreditation Program (EMLAP). Total fungal counts have been summarized in the following graph: Total Fungal Count (count/m 3 ) 2nd W Corridor nd Corridor st Corridor 108 Cafeteria Outdoors Total Fungal Count (count/m3) Generally, it is desirable to have the inside concentrations of bioaerosols to be less than those found outside and with the same proportion of genera as outside. However, variations to this are often expected as the indoor air does not directly correlate with fluctuations in outdoor mold counts. In addition, during colder months with snow cover, outdoor fungal counts are often suppressed so outdoor samples may not be relevant. Therefore, samples from complainant areas are compared against baseline areas, or comparisons are made by looking at the results from multiple sampling locations. Inside concentrations that are significantly higher or consist of different genera than those found elsewhere may indicate amplification or reservoirs within that area. AETHER would consider results from each of the selected areas to be consistent with a normal indoor fungal ecology.

11 Lincoln School Limited IAQ Services February CONCLUSIONS AND RECOMMENDATIONS Our services did not indicate areas of significant concern within the school; however, deficiencies were noted that could promote poor indoor air quality or the perception of poor indoor air quality. AETHER provides the following conclusions and recommendations for the subject site: Carbon Dioxide None of the selected areas exceeded the recommended limit. Relative Humidity As mentioned, relative humidity within the sampled locations fell below 30%. Your mechanical contractor should be consulted to determine if the ventilation systems have installed humidity control capabilities. Unfortunately, it may be that relative humidity is a variable that is not practical to control. However, you should be aware that this issue could contribute to many of the reported concerns regarding perceived poor indoor air quality since low humidity can increase occupant discomfort, cause eye irritation and stuffy noses, aggravate allergies and potentially increase the survival and transmission of some viruses. AETHER has found that during colder months many perceptions of poor air quality and complaints of suspect mold growth causing respiratory issues are actually the result of low relative humidity. Being aware of this condition oftentimes helps alleviate concerns that occupants have regarding air quality. Temperature Most rooms exceeded the recommended limit for temperature in winter. In addition, multiple occupants expressed to AETHER that it was too hot and they had to cover vents and open windows. Although this primarily impacts occupant comfort, it also impacts operating costs. Maintaining temperatures at a lower level, still acceptable for the occupants, can result in energy savings as well as a more comfortable environment. Carbon Monoxide Detectable concentrations of Carbon Monoxide were not measured in the sampling locations. Mold Mold analytical results were consistent with a normal fungal ecology for each of the areas tested and AETHER did not observe suspect mold growth. Visual Summary In general, exposed surfaces within the school were visibly clean. However, the following general observations were made in multiple locations: o Stained ceiling tiles were seen in multiple locations. AETHER recommends that sources of water intrusion be corrected, visually assess for mold and water damaged materials in the plenum and any stained or water impacted ceiling tiles be replaced promptly. It is important to note that the results are considered snap-shots in time and conditions can change from one area to another or over time. Care should be taken to recognize individual reports of concerns within specific areas and ensure that they are addressed rather than attempting to extrapolate findings contained herein to determine the validity of the concern. Although these results should not be used to negate a concern within a specific area, it may be prudent to assume some of the observed deficiencies occur beyond the tested areas and they should be evaluated and corrected, if applicable.
