This section applies to the installation or retrofitting of heating, ventilation, and air conditioning systems for projects where the total project cost per site exceeds $1,400,000.
For purposes of this section, system inspector means:
(1) a Minnesota-licensed architect or engineer; or
(2) properly qualified testing and balancing agency or individual.
Prior to occupying or reoccupying a school facility affected by this section, a school board or its designee shall submit a document prepared by a system inspector to the building official or to the commissioner, verifying that the facility's heating, ventilation, and air conditioning system has been installed and operates according to design specifications and code, according to section 123B.71, subdivision 9, clause (6), item (iii). A systems inspector shall also verify that the facility's design will provide the ability for monitoring of outdoor airflow and total airflow of ventilation systems in new school facilities and that any heating, ventilation, or air conditioning system that is installed or modified for a project subject to this section must provide a filtration system with a current ASHRAE standard.
If the document submitted by the school board to the local building official or the commissioner does not demonstrate to that official's satisfaction that the heating, ventilation, and air conditioning system has been installed correctly or that the system is not operating at a level to meet design specifications, the official or commissioner may allow up to one year of occupancy while the heating, ventilation, and air conditioning system is improved to a level that is considered satisfactory by the system inspector.
