Requirements Specific To: HVAC System 1 1. The specified heating and/or cooling equipment is covered by the ASHRAE 90.1. Code and must meet the following minimum efficiency: Duct Furnace (Gas): 80% Ec 2. The specified heating and/or cooling equipment is covered by ASHRAE 90.1 Code and must meet the ibllowing minimum efficiency: Roofiop Package Unit: 10.3 EER 3. An integrated air economizer is required for individual cooling systems over 65 kBtu/h in the selected climate.

Design heating and cooling loads for the building must be determined using procedures equivalent to those in Chapters 27 and 28 of the ASHRAE Handbook of Fundamentals or an approved equivalent calculation procedure. 2. All equipment and systems must be sized to be no greater than needed to meet calculated loads. A single piece of equipment providing both heating and cooling must satisfy this provision for one function with the capacity for the other function as small as possible, within available equipment options. - Exception: The equipment and/or system capacity may be greater than calculated loads for standby purposes. Standby equipment must be automatically controlled to be oft when the primary equipment and/or system is operating. -Exception: Multiple units of the same equipment type whose combined capacities exceed the calculated load are allowed if they are provided with controls to sequence operation of the units as the load increases or decreases. 3. Each heating or cooling system serving a single zone must have its own temperature control device. 4. Each humidification system must have its own humidity control device. 5. Thermostats controlling both heating and cooling must be capable of maintaining a 5 degree F deadband (a range of temperature where no heating or cooling is provided). - Exception: Deadband capability is not required ifthe thermostat does not have automatic changeover capability between heating and cooling. 6. The system or zone control must be a programmable thermostat or other automatic control meeting the following criteria:a) capable of setting back temperature to 55 degree F during heating and setting tip to 85 degree F during coolingb) capable of automatically setting back or shutting down systems during unoccupied hours using 7 difii✓rent (lay scliedulesc) have an accessible 2-hour occupant overrided) have a battery back-up capable of maintaining u programmed settings for at least 10 hours without power. - Exception: A setback or shutoff control is not required on thermostats that control systems serving areas that operate continuously. - Exception: A setback or shutoffcontrol is not required on systems with total energy demand of 2 kW (6,826 Btu/h) Or less. 7. Outdoor -air supply systems with design airflow rates >3,000 cGn of outdoor air and all exhaust systems must have dampers that are automatically closed while the equipment is not operating. 8.

Operation and maintenance documentation must be provided to the owner that includes at least the following information:a) equipment capacity (input and output) and required maintenance actiousb) equipment operation and maintenance manualsc) �WAC system control maintenance and calibration information, including wiring diagrams, schematics, and control sequence descriptions; desired or field -determined set points must be permanently recorded on control drawings, at control devices, or, for digital control systems, in programming commentsd) complete narrative of how each system is intended to operate. 13. Each supply air outlet or diffuser and each zone terminal device: (such as VAV or mixing box) must have its own balancing device. Acceptable balancing devices include adjustable dampers located within the ductwork, terminal devices, and supply air diffusers. 14. Service water heating equipment must meet minimum Federal efliciency requirements included in the National Appliance Energy Conservation Act and the Energy Policy Act of 1992, which meet or exceed ASHRAE 90.1 Code. New service water heating equipment can be assumed to meet these requirements. 15. Water -heating equipment must be provided with controls that allow the user to set the water temperature to 110 OF for dwelling units acid 90 °F for other occupancies. Controls rraust limit output temperatures of lavatories in public facility restrooms to 110 'F. 16. Stair and elevator shaft vents must be equipped with motorizes[ d:unpers capable of being automatically closed during normal building operation and interlocked to open as required by lire and smoke detection systems. All gravity outdoor air supply and exhaust hoods, vents, and ventilators niiist be equipped with motorized dampers that will automatically shut when the spaces served are not in use. Exceptions: - Gravity (non -motorized) dampers are acceptable in buildings less than three stories in height above grade. - Ventilation systems serving unconditioned spaces.
