The guidance should be applied to each unique climate zone, unique school building and HVAC system. 10-23-2020 2 . If filter racks can accept a minimum MERV 13 filter but were not part of the original design, the following analysis can be completed by internal staff or a consulting engineer: Provide Information previously gathered in the Gathering Stage to individual completing additional analysis. As yet another COVID-19 mitigation strategy, several Lehigh Valley school districts have purchased what the CDC still considers an "emerging technology" to purify their air: bipolar ionization units. Review air distribution conditions of existing spaces (look for covered diffusers, blocked return grilles, overly closed supply diffusers/registers and return/exhaust grilles creating short cycling, possible measurements of airflows by commissioning or balancing professionals, possible review of overall system configuration by design professional, etc.) Determine the area of filter banks. Return to Indoor Air and Coronavirus (COVID-19). Filters range in size but the typical depths of filters are 1", 2", 4" and 12-15". COVID-19 SCHOOL BUILDING HVAC CHECKLIST. Daily flush prior to occupancy: Mechanical Systems should be operated in occupied mode (including normal or peak outside air rate introduced to each space) for minimum period of 2 hours prior to occupants re-entering building. Guidance for schools can be found in CDC’s guidance for improving ventilation and increasing filtration in schools, the ASHRAE guidelines for schools and universities, and the ASHRAE guidance for the re-opening of schools. May need to review previous filter orders. 2 Startup Checklist for HVAC Systems Prior to Occupancy. The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) has developed proactive guidance to help address coronavirus disease 2019 (COVID-19) concerns with respect to the operation and maintenance of heating, ventilating and air-conditioning systems. Once completed, the list will provide a … Consider changing out motor to increase static pressure available, but this may require significant electrical modifications. This may lead to DX low suction pressures which causes faults in cooling or DX high pressure trips in heating with HP's. General inspection of spaces to identify any potential concerns for water leaks or mold growth that could negatively impact occupant health. If the project is a LEED or CHPS project then the filters should already be designed for MERV 13. United States CDC Considerations for Institutions of Higher Education. COVID-19 (May 2020), and the ASHRAE Guidance for Re-Opening Buildings. Hire local trades as needed: plumbing repairs; electrical upgrades; masonry and walkway repairs; lead and/or asbestos remediation; green-scape grounds to direct water away from foundations and reduce run-off; plant shade trees; use native species. Please refer to the Centers for Disease Control and Prevention (CDC) website for the most recent updates related to COVID-19 and schools: ... ASHRAE has developed proactive guidance Exitto help address COVID-19 concerns with respect to the operation and maintenance of heating, ventilating and air-conditioning systems. Select guidance that is likely applicable for educational facilities includes: These recommendations and strategies are organized in order from simple first steps, more involved next steps and then more long-term improvements. COVID-19 SCHOOL BUILDING HVAC CHECKLIST 2015 Michigan Mechanical Code, ASHRAE Standards 55 & 62.1, and ASHRAE COVID -19 Guidelines . There are different processes and purposes for naming viruses and diseases. Read ASHRAE guidance. Golden Gate ASHRAE - COVID-19 Fundraising Efforts. Unitary and Single Zone Equipment (For example: Wall Hung Units, Unit Ventilators, Mini-Splits, Packaged Terminal Air Conditioners, Water-Source Heat Pumps, Fan Coil Units): Monthly Check for particulate accumulation on filters, replace filter as needed. As a result, ASHRAE’s recommendation, as well as the recommendation of the CDC, highlights the use of high‐efficiency filters. DSA is committed to helping California public schools prepare to re-open under the Centers for Disease Control’s COVID-19 requirements. Coordinate with local utilities to identify when buildings will be restarted, identify when systems will be operated (if different than prior operations) and identify that demands may increase (primarily electric but gas may apply as well for some facilities). 11/16/2020. Access ASHRAE's guidance and the association's resource page on the Reopening of Schools and Universities. Ver. Schools can take HVAC survey, qualify for help to reduce harmful aerosol transmissions Jan 13, 2021 Jan 13, 2021 ... MI ASHRAE Chapters’ COVID-19 Task Force chair, at sonya.pouncy@gmail.com. Determine if the speed increase exceeds the maximum motor power. ), Some types or configurations for energy recovery systems allow for exhaust air transfer from the exhaust airstream to the supply airstream, while others do not – depending on system configuration this may be cause for concern. If necessary, vent air from system high points and Verify backflow preventers and pressure regulating valves on makeup water lines are functioning properly. Reference Standard 188 and Guideline 12. Determine if the fan speed can be increased to compensate for the additional pressure drop while maintaining the required airflow. 1: Checklist for Unoccupied Buildings, Checklist No. Recommended guidance is to provide lowest possible particulate concentration anywhere in the space. Consider having airflows and system capacities reviewed by design professionals to determine if additional ventilation can be provided without adversely impacting equipment performance and building Indoor Environmental Quality (IEQ). Retain in-house facility workers: clean, disinfect, maintain building systems; assess asbestos and lead paint status; pest-proof inside and out; check water and ventilation filters; assess water damage, fix leaks. Review condition of cooling coils in air handling equipment – if issues with condensate drainage are identified or biological growth is identified, corrective action should be taken to clean or repair. Work with a reputable ventilation engineer or UV system designer. 11/30/2020. Address or clear existing alarms from Building Automation Systems/Building Management Systems to allow for recognition of new alarms that may impact building indoor air quality and consider alarm hierarchy.
