Exterior doors (except for momentary entry and exit) Other openings to the exterior as a result of disrepair incomplete construction or structural defect. Heating and cooling systems Set to operate at normal occupied temperatures : 65˚ - 80˚ F (18˚ - 27˚ C). Note—Maintenance inspections of HVAC systems are recommended, but not required. Variable Outdoor Air Ventilation Systems (if any) Automated or manually operated systems that seasonally vary outdoor air ventilation for energy savings or comfort, for: — individual rooms and dwellings — multiple rooms and dwellings; or — the whole building. Such systems include: Manually operated dampers, Energy Economizer systems, Energy Recovery Ventilators (ERV) and Evaporative cooling systems. Close outside air inlet dampers or set to minimum outdoor air intake settings that apply at all times of the year when a building is significantly occupied. For other systems, such as window air conditioners, dampers to outside air shall be closed. Variable Air Volume (VAV) Systems (if any) Systems that temper room temperatures using thermostats to vary the volume of heated or cooled air coming into rooms. Set all thermostats to between 65-80˚ F (18-27˚ C) in all rooms that are served by the system. Return-Air Ducts laid In Soil (if any) Where return-air air ductwork is located under a slab, or otherwise laid in soil. Alert the testing company immediately HVAC setback in non-residential locations If non-residential rooms are operating with HVAC setback temperatures during nights or weekends that are outside of normal occupied temperatures of 65˚and 80˚ F (18˚ - 27˚ C). Alter to retain temperatures within the range of 65˚and 80˚ F (18˚ - 27˚ C) Or, contact the testing company Note—Text versions of this exhibit in both English and Spanish can be downloaded at www.standards.aarst.org/public-review by choosing “Measurement, User Tools”
