About this file

This is an Indoor Air Quality (IAQ) Verification Report prepared by Sustainable Engineering Solutions, LLC for Conard High School in West Hartford, Connecticut, conducted on behalf of West Hartford Public Schools to comply with Connecticut Public Act No. 23-167. The report documents a comprehensive assessment of the school's HVAC systems, ventilation rates, and filtration efficiency compared to ASHRAE 62.1 standards and the 2022 Connecticut State Building Code. The 287,874-square-foot facility, originally constructed in 1957 with major HVAC upgrades in 1997, was evaluated through systematic testing and balancing conducted by Trueflow Testing and Balancing, LLC, with field measurements of ventilation rates, filter conditions, and damper operations across all air handling units and rooftop units serving classrooms, offices, gymnasiums, cafeterias, and auxiliary spaces.

The verification process identified six initial recommendations and two additional findings requiring corrective action. Primary deficiencies include inoperable pneumatic outside air dampers on AHU-A and AHU-B (serving the majority of classroom and office spaces), non-functional RTU-2 serving the auxiliary gymnasium, out-of-calibration VAV boxes unable to maintain airflow setpoints, inadequate bathroom exhaust ventilation in multiple spaces, and filters currently rated MERV 8 or 10 that should be upgraded to MERV 13. The report recommends implementing electronic damper controls with balanced minimum and maximum outside air CFM values, recalibrating all VAV boxes with controller replacements if necessary, and establishing demand control ventilation programming utilizing existing CO2 sensors with a 900 ppm setpoint. Additionally, mechanical ventilation should be added to the REACH outbuilding, which currently relies solely on operable windows. The assessment notes that while many spaces satisfy code requirements through operable windows, this approach is not practical during periods of extreme weather and does not provide reliable indoor air quality control.

Executive Summary Sustainable Engineering Solutions, LLC (SES) and Trueflow Testing and Balancing were retained by the Town of West Hartford to provide professional engineering and test and balancing (TAB) services to meet the indoor air quality (IAQ) verification requirements of the state legislation Public Act No. 23-167 at Conard High School. This combined effort successfully completed the required verification as outlined in the legislation. With a focus on validating and improving indoor air quality, SES and Trueflow systematically assessed each air handling system to measure current ventilation rates, filtration rates and distribution levels compared to current ventilation standards.

The majority of spaces within the building do not meet the calculated minimum ventilation requirements without operable windows, primarily due to the inoperability of the outside air dampers on AHU-A and AHU-B, which serve most areas of the school. Relying on operable windows as the primary source of ventilation is not recommended, as it results in poor temperature control. This report includes recommendations related to the building’s air handling units, VAVs, and exhaust fans, along with additional findings, for the Client's review.

Note that throughout this report the term “ventilation” air and “outside” are used interchangeably and are one in the same.

IAQ Verification Process Filter Evaluation As required by the law, the team reviewed the current level of filtration installed on each air handling system and analyzed the feasibility of increasing the filter ratings to MERV 13. A filter’s minimum efficiency reporting value, or MERV, is a rating system that measures how efficient a filter is at trapping harmful particulate matter, dust, and debris in the air. This rating system categorizes filters into a ranking from 2 to 20, with a MERV 8 being the standard. A higher MERV rating means that a filter is more efficient and MERV 13 is recommended for many commercial and industrial buildings and by state code. At its minimum, a MERV 13 filter traps more than 70% of air particles that are 0.3 to 1.0 microns in size and is at least 90% effective when the particles increase to 3 to 10 microns in size. Along with assessing the filter efficiencies, the condition of unit’s filters and proper sealing of the filter banks to eliminate bypass air was also assessed.

Ventilation Evaluation The amount of ventilation air delivered into interior occupied spaces is governed by the 2022 Connecticut State Building Code, which references ASHRAE Standard 62.1. This code prescribes the flow rate of ventilation air that must be supplied mechanically, or otherwise, to occupied areas based on occupancy classifications. Depending on the type of use of a space and total space area, outdoor air flow rates in cubic feet per minute (CFM) per person and square foot are defined when the parameters are known. When total occupants per space are unknown, the code defines occupant density for each classification type in number of occupants per space floor area. The final flow rate in CFM for every occupied space can thus be calculated.

As an alternative to providing outside air mechanically to occupied spaces, the building code also allows for outside air to enter occupied areas naturally through operable windows. If the area of operable windows for an occupied space is at least 4% of the space’s floor area, mechanical ventilation for that space is not required by code. However, although spaces with sufficient operable window area may satisfy code requirements, this is not a realistic way of providing adequate ventilation during periods of cold or hot weather.

The amount of outside air supplied to occupied spaces is important for occupant comfort and health because contaminants generated by people and materials in the space must be removed or they will build up to unhealthy levels. Diluting interior air with outside air reduces the concentration of carbon dioxide, volatile organic compounds (VOCs) along with various airborne viral and bacterial contaminants.

Demand Control Ventilation In certain applications, the amount of outside air delivered to a space can be reduced if occupancy and indoor air quality can be safely monitored and controlled. This is most typically accomplished through monitoring carbon dioxide (CO2) and occupancy sensors in the space, otherwise known as “Demand Control Ventilation” or DCV. As occupancy rises in a space, so does the amount of CO2 as a result of the occupant’s natural respiration and exhalation of CO2. By monitoring CO2 and occupancy status, an HVAC system can reduce the amount of outside air to a zone when levels and occupancy are low. If CO2 levels rise above a certain threshold or occupancy is detected, the HVAC system can then increase the amount of fresh air until the levels fall back below an acceptable level. Having an operational demand control ventilation strategy in place will help reduce energy consumption of a facility while simultaneously ensuring all spaces are achieving the required fresh air requirements.

Project Approach During the review of the school, SES took the following steps to complete the study:

• Develop an IAQ evaluation plan and conduct a kickoff meeting with the client and Trueflow to review the plan, project schedule, access, etc.

• Perform a walkthrough of the building to review the HVAC systems providing ventilation air for a condition assessment of the systems, identify remaining useful life and understand any maintenance issues that may be related.

• Review available documentation for the HVAC systems that includes:

o As-built drawings or original design drawings o O&M documentation for systems performance data o Any previous testing adjusting and balancing reports from the HVAC systems o Documentation describing the chronology of known problems, system failures, complaints, and alterations.

• Develop IAQ evaluation documentation for field evaluation of equipment.

• Perform field evaluation of equipment for ventilation sequence of operation and verify calibration of CO2 sensors where used (+/- 50 PPM).

• Review Trueflow’s completed ventilation rate verification sheets for each space for compliance with ASHRAE 62.1

• Review the Trueflow’s completed unit data sheets for each system providing ventilation air for ventilation airflows, filter condition and efficiency, damper conditions and maintenance adequacy.

• Prepare a report that summarizes the verification process, identifies any deficiencies that require correction and any recommendations to address the deficiencies found and next steps.

Building: Conard High School

Location: 110 Beechwood Rd, West Hartford, CT 06107

Building Size (gross):

287,874 sq. ft.

Year Constructed:

1957 (original)

Building Use (current):

High School

Conard High School is a 287,000 square foot building, originally constructed in 1957. A major HVAC upgrade took place in 1997, installing several new roof top units, VAVs and other terminal devices. The building houses a variety of spaces, including gymnasiums, an auditorium, cafeteria, classrooms, offices and more. A REACH out building provides additional classroom and office spaces for the campus.

Occupancy The building is occupied Monday through Friday between 7am and 5pm. Special events are held on the weekends and after hours as needed for school extracurricular activities. In addition, the school hosts summer school activities during the summer break.

Building Automation System Description The HVAC system is controlled by a Niagara framework building automation system. This system has graphics for all of the air handling units and is capable of trending and writing custom control algorithms. All dampers for AHU-A & B have pneumatic controls.

HVAC Systems Description

Air Handling Units Two air handling units, AHU-A and AHU-B, provide conditioned air to the majority of classroom and office spaces throughout the entire building. Each space served by the air handling unit has their own individual pneumatic zone bypass damper and hot/cold deck zone damper, the modulation of which control the temperature and quantity of air provided to each zone. Each air handling unit has return plenums. Supply fan speed modulates for each AHU based on calls for heating/cooling or demand control ventilation demand.

Unit Tag Serves AHU-A Building B AHU-B Building A

Roof Top Units Seven energy recovery units are installed on the roof of the school buildings and serve a variety of the larger spaces. RTU-1, 3 & 4 serve VAVs and modulate supply fan speed to maintain a supply air static pressure setpoint. RTU-2, 5, 6 & 7 modulate supply fan speed based on calls for calls for heating/cooling or demand control ventilation demand.

Recommendations The following recommendations were made based on the review of TAB report, ventilation comparisons to the IMC Minimum Ventilation Rates (2021) and industry best practices. Additional supporting information can be found in the Appendices of the report.

Due to the limited area of focus of the required IAQ verification and this review, SES strongly recommends verifying the condition of all related HVAC equipment components and control functionality outside of the scope of this verification, prior to implementing any modifications to the HVAC systems.

Initial Recommendations

• Recommendation #1: Replace Pneumatic Controls For AHU-A & AHU-B and Rebalance Outside Air

• Recommendation #2: Repair RTU-2

• Recommendation #3: Recalibrate VAV System and Rebalance RTU-1, 3 & 4

• Recommendation #4: Rebalance/Repair Bathroom Exhaust Fan/s

• Recommendation #5: Filter Improvements

• Recommendation #6: Add Mechanical Ventilation To REACH Building

Recommendation #1: Replace Pneumatic Controls For AHU-A & AHU-B and Rebalance Outside Air During testing and balancing, AHU-A & AHU-B, which serve a majority of the high school buildings, were found to utilize pneumatic controls for unit damper actuation and zone damper actuation. While taking TAB measurements, the outside air dampers were found to be inoperable for both units and were stuck in their current positions. Because of the inoperable outside air dampers, minimum ventilation requirements in the spaces were not met. However, a majority of spaces served by AHU-A & B are satisfied by code due to the presence of operable windows, operable windows are not the ideal means for ventilation as it relies on occupants manually opening windows.

SES recommends that the pneumatic outside air and return air dampers and actuators are replaced with electronic actuators and new dampers. In addition, the new dampers should be balanced to the calculated minimum and maximum outside air levels on the table below. A fixed damper position for min and max airflow should be recorded for use during existing demand control programming. Although units are approaching the ends of their usable lives, SES believes that by replacing pneumatic damper controls with electronic will extend the lifespan of the existing AHU-A & B.

Unit Tag MIN-OAD (CFM) MAX-OAD (CFM)

AHU-A 8,880 26,660

AHU-B 5,260 33,780

Scope Of Work

1. ATC to replace existing outside air dampers (2) and return air dampers (2)

2. ATC to install electronic actuators and tie into existing building management system

3. TAB Rebalance outside air for AHU noted in table above to new minimum and maximum outside air CFM noted above.

4. ATC to assist with balancing efforts as needed.

5. ATC to update min OAD setpoint in BMS programming for AHU-A and B in all modes.

6. ATC to update max OAD setpoint in BMS programming for AHU-A and B under calls for demand control ventilation.

Recommendation #2: Repair RTU-2 RTU-2 serves the auxiliary gym and several nearby spaces. During onsite conversations with the HVAC contractor, it was found that RTU-2 had been disabled due to excessive noise generated in the auxiliary gym. During testing and balancing, the TAB contractor enabled the RTU to record measurements and the unit supply fan did not enable. It is unclear why the supply fan did not operate.

SES recommends that a service contractor is brought in to review the operation of RTU-2’s supply fan and repair components as needed. Once repaired, RTU-2 should be reverified to ensure the associated spaces meet ventilation requirements.

Scope Of Work

1. Town of West Hartford to schedule McQuay service technician to review and correct operation of RTU-2

Recommendation #3: Recalibrate VAV System and Rebalance RTU-1, 3 & 4 During testing, adjusting and balancing it was determined that the majority of the VAV boxes are out of calibration and unable to control to their airflow setpoints. Many VAV boxes were found to be wide open or fully closed.

SES recommends recalibrating all VAV boxes so that they can properly maintain the associated airflow setpoints. In the event VAV controllers are failed or inoperable they should be replaced.

Once this work has been completed, the outside air dampers for RTU-1, 3 & 4 should be rebalanced and new MIN-OAD and MAX-OAD damper setpoints established that correspond to the airflows listed in the table below. See table below for minimum and maximum outside airflows.

Unit Tag MIN-OAD (CFM) MAX-OAD (CFM)

RTU-1 1,140 4,850

RTU-3 410 1,220

RTU-4 1,410 3,190

1. TAB and ATC to recalibrate all VAV boxes

2. ATC to replace VAV controllers (if necessary)

3. TAB to rebalance outside air for RTU noted in table above to new minimum and maximum outside air CFM noted above.

4. ATC to assist with balancing efforts as needed.

5. ATC to update min OAD setpoint in BMS programming in all modes.

6. ATC to update max OAD setpoint in BMS programming for demand control ventilation.

Recommendation #4: Rebalance/Repair Bathroom Exhaust Fan/s During review of TAB data, the following bathrooms do not meet exhaust ventilation requirements. Due to the age of the building and missing drawings, the exact exhaust fan intended to ventilate each space could not be determined. In review of the building automation system for the building, several exhaust fans are in alarm. Operation of exhaust fans and condition of exhaust duct in these spaces should be reviewed.

SES recommends that exhaust fans and exhaust duct connections in these spaces be reviewed for proper operation, functionality and that all connections remain.

Scope Of Work

1. ATC to review active alarms tied to exhaust fans.

2. Town of West Hartford to determine which exhaust fan serves which bathroom.

3. Town of West Hartford to review each space and perform corrective action as required.

Recommendation #5: Filter Improvements Currently, all air handling units were found to utilize MERV 8 or 10 filters.

SES recommends replacing and upgrading all final filters to at least MERV 13 for increased filtration efficiency.

Recommendation #6: Add Mechanical Ventilation To REACH Building Currently, the REACH outbuilding on the Conard campus, which houses classrooms, a computer lab and office spaces relies solely on operable windows to provide ventilation to the spaces within. As stated above, this is not a preferable method of ventilation. SES recommends the client review options for providing mechanical ventilation to the building with a licensed MEP firm.

Additional Findings In addition to the above-mentioned recommendations specific to the focus of this program, SES has identified the following operational deficiencies that we recommend are further reviewed and possibly implemented.

Finding #1: Enhance Existing Demand Control Ventilation for RTU-5, 6 & 7 RTU-5, 6 & 7 are currently equipped with demand control ventilation and CO2 monitoring. Under normal conditions, the units operate at the minimum outside air damper position (MIN-OAD). When space CO2 levels exceed the setpoint (1,000 PPM), the supply fan modulates speed towards 100%. As CO2 levels drop below the setpoint, the supply fan returns to the minimum speed setpoint.

SES recommends implementing demand control ventilation programming that modulates the outside air damper on a call for demand control ventilation in opposition to the supply fan speed. A new fixed minimum and maximum damper position should be balanced to meet the calculated CFM in the table below.

Proposed Outside Airflow Setpoints Unit Tag MIN-OAD (CFM) MAX-OAD (CFM)

RTU-5 620 840

RTU-6 250 550

RTU-7 250 530

Under the current configuration, the RTU is over ventilating the space at minimum and maximum airflow setpoints. As an energy savings opportunity, the minimum and maximum airflow set points can be reduced to just the ventilation rate required based on square footage and occupancy. SES recommends the following actions:

• A TAB contractor should determine new MIN-OAD and MAX-OAD damper percentages that correspond to the airflows listed in the table above.

• The updated setpoints should be incorporated into the BAS sequence, existing demand control ventilation logic shall be modified to modulate damper position in lieu of fan speed.

• New CO2 return air CO2 setpoint shall be 900ppm.

1. TAB to rebalance the RTU minimum and maximum outside air damper setpoint to coincide with the new calculated minimum and maximum outside air CFM.

2. ATC to assist in balancing efforts as needed.

3. ATC to update min and max OAD setpoint in BMS programming for RTUs while under calls for demand control ventilation.

4. ATC to program new return air CO2 setpoint and adjust programming to modulate OAD.

Finding #2: Implement Demand Control Ventilation For Air Handling Unit - AHU-A & B and RTU-1, 3 & 4 AHU-A and B and RTU-1, 3 and 4 serve various classroom and office areas throughout the building. Due to the highly transient occupancy of these spaces, demand control ventilation programming should be implemented to fluctuate the quantity of outside air supplied to the space base on the actual space requirements. These systems should dynamically adjust ventilation rates based on occupancy levels, ensuring optimal indoor air quality (IAQ) while conserving energy during periods of low usage.

SES recommended implementing a demand control ventilation control sequence for each AHU/RTU as follows:

1. Utilize existing return air CO2 sensor in programming.

2. New MIN-OAD and MAX-OAD damper percentages balanced per recommendation #1 & 3 shall be utilized in the programming of demand control ventilation for the units.

3. A sequence should be programmed for the AHU/RTUs as follows: “Under normal conditions, the unit operates at the minimum outside air damper position (MIN-OAD). When space CO2 levels exceed the setpoint, the outside air damper modulates to the maximum damper position (MAX-OAD); subject to a low mixed air temperature of 50°F (adj.). As CO2 levels drop below the setpoint, the damper position returns to MIN-OAD.”

4. New return air CO2 setpoint shall be 900ppm (adj.)

1. ATC to program demand control ventilation programming per sequence of operations noted above.

2. ATC to program new return air CO2 setpoint.

Next Steps

Review Recommendations It is recommended that the client review this report and the proposed recommendations for further clarification, if needed and decide a course of action. SES can provide additional assistance if needed, to further analyze and develop these recommendations for future implementation, and if desired, provide commissioning of the implemented measures.
