                                 CODE OF VIRGINIA

INDUSTRY-RECOGNIZED UNIFORM INSPECTION AND EVALUATION (§ 22.1-141.5)

A. At least once every four years, each local school division shall provide for
an industry-recognized uniform inspection and evaluation of the heating,
ventilation, and air conditioning system in each public school building in the
local school division. Such inspection and evaluation shall be performed by a
certified testing, adjusting, and balancing technician, an industrial hygienist
certified by the American Board of Industrial Hygiene, a technician with a
Master HVAC License from the Department of Professional and Occupational
Regulation, or a mechanical engineer. Such heating, ventilation, and air
conditioning systems inspection and evaluation shall include:

   1. Testing for maximum filter efficiency;

   2. Physical measurements of outside air delivery rate;

   3. Verification of the appropriate condition and operation of ventilation
   components;

   4. Measurement of air distribution system outside air, return air, and supply
   air and static pressure readings across all air handling unit components,
   including filters, coils, and fans;

   5. Verification of unit operation and that required maintenance has been
   performed in accordance with the most recent indoor ventilation standards
   promulgated by the American Society of Heating, Refrigerating and
   Air-Conditioning Engineers;

   6. Verification of carbon dioxide sensors and acceptable carbon dioxide
   concentrations indoors; and

   7. Collection of field data for the installation of mechanical ventilation if
   none exists.

B. The portion of the uniform inspection and evaluation required pursuant to
subsection A that relates to the ventilation system shall identify the extent to
which each school&#8217;s current ventilation system components, including any
existing central or noncentral mechanical ventilation system, are operating in
such a manner as to provide appropriate ventilation to the school building in
accordance with the most recent indoor ventilation standards promulgated by the
American Society of Heating, Refrigerating and Air-Conditioning Engineers.

C. Each local school division shall prepare a written report of the results of
the uniform inspection and evaluation required pursuant to subsection A that
includes any corrective actions necessary to be performed on the mechanical
ventilation system or the heating, ventilation, and air conditioning
infrastructure, including installation of filters meeting the most optimal level
of filtration available for a given heating, ventilation, and air conditioning
system, installation of carbon dioxide sensors, and additional maintenance,
repairs, upgrades, or replacement. Each local school division shall make such
report available for public inspection at a regularly scheduled local school
board meeting and on the local school board&#8217;s public website.

D. No local school division is required to provide for a uniform inspection and
evaluation pursuant to subsection A for any school building that will cease to
be used as a school within one year of such a planned inspection and evaluation.
