Section Ed 321.17 - Heating, Ventilating, and Air Conditioning (HVAC) Requirements(a) Schools shall be designed, constructed, and maintained to provide: (1) Code compliant outside air ventilation and exhaust systems to aid in the maintenance of indoor air quality; and(2) Code compliant heating temperatures throughout occupied building areas.(b) In cases where air conditioning is provided, schools shall be designed, constructed, and maintained to provide code compliant cooling temperatures throughout all air conditioned spaces.(c) The design and installation of all HVAC systems shall comply with: (1) The state building code under RSA 155-A;(2) The code for energy conservation in new building construction under RSA 155-D; and(3) The state fire code under Saf-C 6000 as adopted by the commissioner of the department of safety under RSA 153 and as amended pursuant to RSA 153:5, I by the state fire marshal with the board of fire control.(d) A school district may use energy recovery ventilation equipment in its school buildings for transfer of sensible and latent or sensible or latent energy from exhaust air to outside air. For the purposes of this paragraph, the transfer of sensible and latent or sensible or latent energy from exhaust air to outside air means the practice of extracting heat from exhaust air to limit the amount of new energy that is used to heat additional air from outside.(e) Project construction documents shall require the HVAC contractor to provide the school maintenance personnel with record drawings, appropriate training, operating and maintenance manuals, and any other relevant information concerning the HVAC systems and components thereof.(f) Project construction documents shall require a formal commissioning process for HVAC systems start-up and initial operation. At a minimum, the construction documents shall identify the requirement for the development of a written commissioning plan specific to the project. The commissioning plan shall identify a process of ensuring that prior to completion of a construction project, new and/or modified HVAC systems perform in accordance with the design intent and the construction documents. The commissioning process shall include, but shall not be limited to, verification and functional performance testing on all HVAC equipment and controls, in all operating modes.(g) Verification that construction has been performed according to state and local building codes and approval of variances shall be the responsibility of the local code enforcement official in the municipality in which the construction takes place, or the state fire marshal in accordance with RSA 155-A:7.N.H.
