Status of School HVAC Analyses
In preparation of the opening of the school year, the district asked the highly qualified HVAC experts employed by the Town of Andover Facilities Department to evaluate the ventilation systems in each schoolhouse. They produced information that was posted to the Return to School webpage. In summary, their analysis concluded that HVAC systems within Andover schools follow current ASHRAE 62 standards or local ventilation standards for minimum outside air requirements.
Additionally, at the request of the Andover Education Association, the district recently entered into a contract with an outside HVAC contractor, NV5, to conduct an independent inspection of the ventilation systems in each school building. A report will be provided reflecting the independent contractor’s findings for each individual building. The contractor was expected to finish its evaluation and report on or before September 4, 2020. As of September 8, 2020, NV5 has not yet completed its evaluation of all of our school buildings, with two buildings left to evaluate. They will then prepare a comprehensive report, which will be made available to the public.
