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 Sedgwick 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.

Approximately half of the spaces in the school building do not meet ventilation requirements due to the age of existing mechanical equipment. Spaces that are noted to meet ventilation requirements do so due to proper operation and balancing of devices or presence of operable windows. Utilizing operable windows as the primary means of ventilation is not recommended due to poor temperature control. Recommendations associated with the buildings air handling units, heating ventilators and exhaust fans, along with additional findings, have been included in this report for the Client to review.

Overall, the majority of HVAC air handling systems were found to be nearing the end of their useable lives. The survey identified zones with ventilation below required levels, primarily due to age of equipment and additionally required balancing.

All AHUs also require filter replacements. Additionally, SES identified one energy conservation opportunities for further consideration.

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

Middle 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: Sedgwick Middle School

Location: 128 Sedgwick Road, West Hartford, CT 06107

Building Size (gross):

179,850 sq. ft.

Year Constructed:

1931 (original)

Building Use (current):

Middle School

Sedgwick Middle School is a 179,850 square foot building, constructed in 1931. In 2001, an HVAC renovation occurred, which installed new air handling units, terminal devices and pumps. The school building houses a large variety of spaces, including a gymnasium, auditorium, library, cafeteria, classrooms, science laboratories, music rooms and offices.

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 a majority of the air handling units and is capable of trending and writing custom control algorithms. Currently, the majority of terminal equipment is controlled locally or pneumatically.

HVAC Systems Description

Air Handling Units Eight air handling units are installed throughout the building. Of the air handling units, three (AHU-1, AHU-5 & AHU-6) appear to be newer and more recently replaced than the others and are connected to the building management system. The York AHU-1 is variable speed and provides conditioned air to downstream VAVs. The other five air handling units are not connected to the BMS. The older five air handling units appear to be nearing or at the end of their useable lives.

Exhaust Fans Exhaust fans are located throughout the penthouse and roof area of the original school building. Exhaust fans on the BMS are located in the new addition.

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 HV-1 & HV-4

• Recommendation #2: Replace Four Penthouse AHU and Associated Ductwork

• Recommendation #3: Rebalance Outside Air For AHU-1 (York), RTU-1 & 1B and FCU-1

• Recommendation #4: VAV Calibration

• Recommendation #5: Replace Toilet Exhaust Fans

• Recommendation #6: Filter Improvements

Recommendation #1: Replace Existing HV-1 & HV-4 During testing and balancing, HV-1 and HV-4, which serve gymnasium and fitness spaces, were found to be inoperable. In addition, both units are approaching the end of their expected usable lives. Unit components including casing, ductwork, fan, fan motors and more are deteriorating and have become unreliable for consistent control. The HV units should be replaced in the near future with a single zone air handling units equipped with variable air volume control, heating, cooling and demand control ventilation control. The new units should be integrated into the existing building management system.

Recommendation #2: Replace Four Penthouse AHU and Associated Ductwork Currently, AHU-1, 2, 3, 4, located in the east and west penthouses are not currently integrated into the building management system. The four AHU serve the majority of the original school building. During testing and balancing, measurements taken at the unit show that the units currently have the capacity to meet ventilation requirements of the spaces served. However, readings taken at the space level do not meet ventilation requirements. This is likely due to the age and condition of the ductwork between the AHU and outlets with significant leakage occurring. When walking throughout the building, several locations were noted where air leakage could be heard above the ceiling grid.

SES recommends replacing each AHU and the associated ductwork. The condition of each AHU shows that they are at the end of their usable lives. The control for the existing units is largely pneumatic, the new air handling units should utilize electronic controls/devices, be integrated into the building management system and programmed with demand control ventilation.

Recommendation #3: Rebalance Outside Air For AHU-1 (York), RTU-1 & 1B and FCU-1 In review of the TAB data, the following units were measured to supply lower amounts of outside air than calculated at the time of reading. Although several of these spaces served by these units are currently satisfied via the presence of operable windows, it is not recommended that these spaces rely solely on the operable windows for ventilation. Operable windows are allowable means of ventilation per code, however when utilized for ventilation, typically results in over heating or overcooling of the space. This method of ventilation also requires the occupants to open the windows when in the space which typically does not occur.

SES recommends rebalancing the minimum outside air damper position for each of the units to correlate with the minimum outside airflow CFM described below.

RTU-1B 2,175 3,140

Service Current Outside Air

(CFM)

Required Outside Air CFM)

FCU-1 66 530

Recommendation #4: VAV Calibration The survey revealed that multiple VAVs served by RTU-1B and AHU-1 throughout the building have uncalibrated airflow stations. On the building management system, the airflow measured on the BMS was found to be lower or higher than the value measured by TAB. This discrepancy is causing various spaces to not meet their minimum ventilation or vastly exceed their minimum ventilation requirements. While many of the spaces satisfied the code required ventilation rates, this was largely due to having operable windows. Operable windows are allowable means of ventilation per code, however are not recommended as they typically result in over heating or overcooling of the space. This method of ventilation also requires the occupants to open the windows when in the space which typically does not occur. As the VAVs are the primary source of heating and cooling, proper calibration and operation for the VAVs should be restored.

As a result of the issues identified above, SES recommends the airflow stations for the VAVs in the following table are re-calibrated and re-balanced to their desired airflow setpoints. After, a point-to-point checkout should be carried out to ensure the readings shown on the BMS reflect the actual quantity of air delivered to space.

If after re-calibration, the space continues to not meet airflow requirements, it is recommended that the VAV and controller are reviewed for a potential repair or replacement.

Recommendation #5: Rebalance/Replace Penthouse 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. The exhaust fans serving these spaces are believed to be located in the penthouse or on the roof of the original school building. 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.

Recommendation #6: Filter Improvements Currently, the majority of air handling units were found to utilize custom filters.

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

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 AHU-5 & 6 AHU-5 & 6 is 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 (1,200 PPM), the outside air damper modulates to the maximum damper position (MAX-OAD). As CO2 levels drop below the setpoint, the damper position returns to MIN-OAD. The current MIN-OAD and MAX-OAD damper positions setpoints are described below.

Current Setpoints Unit Tag Served MIN-OAD (%) MAX-OAD (%) AHU-5 Auditorium 25% 100% AHU-6 Band/Chorus 20% 100%

Under the current configuration, the AHU 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 below.

• The updated setpoints should be incorporated into the BAS sequence, ensuring alignment with the current demand control ventilation logic.

Proposed Setpoints

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.
