Ventilation and Filtration. The District will provide the following environments for in-person classroom instruction to take place in those spaces with:
1. Currently equipped with a centralized HVAC system that provides air filtration with a minimum efficiency reporting value (MERV) of 13 or better; or
2. For those occupied areas without a centralized HVAC system that provides air filtration with a minimum efficiency reporting value (MERV) of 13 or better, portable HEPA air filtration units with a clean air delivery rate (CADR) of 250 or greater per 1000 square feet of floor area will be used. The above standards shall apply in each SCUSD facility classroom, auditorium, gymnasium, nurses’ office, or other occupied area in which bargaining unit members are required to report to work.
1. On or before September 2, 2021, and thereafter when any change occurs, SCUSD Facilities Director or other appropriate person or designee will provide to SCTA a list by school and classrooms of which classrooms are equipped with MERV 13 filters and those in which portable HEPA filters are placed. The portable HEPA filters shall be appropriately maintained, according to manufacturers’ recommendations.
2. HVAC systems will be begin running at least two (2) hours before the beginning of the school day and continue for at least two (2) hours after.
3. Occupied spaces will only be used if they are equipped with an HVAC system that provide for the introduction of outside air into the occupied space, or if they are equipped with functional CO2 Monitors.
4. Within two weeks of students returning to each school site, the site will be provided two (2) portable, battery-powered CO2 monitors, or loggers to check classrooms during their peak occupancy. Within two weeks of the resumption of in-person instruction at the site, District facilities staff will conduct a walk-through of each classroom while they are fully occupied to check CO2 levels, and will flag any classroom that registers over 1000 parts per million (ppm). If a classroom registers over 1000 ppm that classroom will not be used until the cause for the high CO2 level has been corrected. Certificated staff member may request a classroom check and be provided the use of the logger, if they detect an immediate problem or concern of a ventilation system failure.
5. Effective September 2, 2021, the District will work with qualified vendors to engineer and install CO2 monitors in rooms that lack compatible controls with the existing building control system. Th...
Ventilation and Filtration. The District will provide the following environments for in-person classroom instruction to take place in those spaces with:
1. Currently equipped with a centralized HVAC system that provides air filtration with a minimum efficiency reporting value (MERV) of 13 or better; or
2. Currently equipped with a centralized HVAC system that provides air filtration with a minimum efficiency reporting value (MERV) of 8, AND, and portable air filtration units with a clean air delivery rate (CADR) of 250 or greater per 1000 square feet of floor area.
Ventilation and Filtration a. In-person instruction will occur in locations with properly maintained HVAC systems equipped with MERV-13 filters, and replace them according to manufacturer recommendations.
i. The District will ensure that all vents are cleaned regularly and filters are replaced every three months per guidance.
ii. Classrooms and workspaces will be allowed to keep doors open to maximize ventilation.
iii. The District shall supply portable air filtration units (rated H13 TRUE HEPA) in every classroom.
Ventilation and Filtration. 1. Prioritize use of indoor spaces that are equipped with a properly maintained and balanced HVAC system that meets or exceeds ASHRAE 62.1

Ventilation and Filtration. (a) Prioritize use of indoor spaces that are equipped with a properly maintained and balanced HVAC system that meets or exceeds ASHRAE 62.1 standards.
(b) Outdoor air supplied by the HVAC should be increased to the extent possible and MERV13 or higher rated filters should be utilized for recirculated air.
(c) Airflow patterns should be balanced to prevent stagnation and short circulating of air and maintaining negative pressure in testing spaces and other critical rooms (e.g. treatment or isolation rooms) in relation to common areas.
(d) CIC Health will implement additional safety infrastructure for the purpose of maintaining appropriate ventilation and filtration in accordance with industry guidelines.
Ventilation and Filtration a. The parties affirm that public health officials indicate that proper ventilation is necessary to minimize the transmission and infection from COVID-19; especially for individuals in a closed space for extended periods of time by reducing the airborne concentration of the virus and thus the risk of transmission and infection of COVID-19 through the air. Our HVAC systems meet the guidelines as specified by the American Society of Heating Refrigerating Air Conditioning Engineers (ASHRAE) which includes the required air exchanges. VUSD HVAC meets the Federal and State guidelines for fresh air exchanges in the room.
b. All locations with functioning windows shall keep them open depending on weather, temperature, and/or air quality conditions.
c. Employees are requested to report suspected non-operational ventilation systems to the site Principal or supervisor.
d. All reported ventilation systems shall be investigated on site within one (1) work day of the report. If necessary, repairs will be started as soon as possible to correct a system that is not working properly.
e. Rooms or buildings/offices with non-operational ventilation systems shall have all employees and students relocated until the ventilation system is working.

Ventilation and Filtration. [This issue is addressed in a separate MOU.] Section VIII: Cleaning and Disinfecting Plans
Ventilation and Filtration. In-person instruction may commence when the following ventilation and filtration mitigation standards are in place at each facility classroom, auditorium, gymnasium, nurses’ office, or other occupied area:
1. currently equipped with a centralized HVAC system that provides air filtration with a minimum efficiency reporting value (MERV) of 13 or better; or
2. Currently equipped with a centralized HVAC system that provides air filtration with a minimum efficiency reporting value (MERV) of 8, AND, portable air filtration units with a clean air delivery rate (CADR) of 250 or greater per 1000 square feet of floor area. In both circumstances, occupied areas shall be equipped with carbon dioxide monitors, according to the provisions of AB 841, section 1625. The monitor will provide carbon dioxide readings to the teacher, and an indicator light or alert system when the carbon dioxide level in a classroom or occupied area has exceeded 1,100 ppm. The District will not use the UDVI portable units in any area where unit members work. The readiness of each classroom shall be verified by a Certified Testing, Adjusting and Balancing (TAB) Technician who shall review the HVAC system, including its capacity and airflow, and ventilation rates in each facility classroom, auditorium, gymnasium, nurses’ office, and other occupied areas. Certification shall be as set forth in AB 841, section 1620. The Certified TAB technician shall prepare an assessment report for each classroom or occupied space for review by a
