Requirements Specific To: HVAC System EH-1 : None Requirements Specific To: HVAC System EH-2 : None Requirements Specific To: HVAC System EH-3 : None Generic Requirements: Must be met by all systems to which the requirement is applicable: 1.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(s): -The equipment and/or system capacity may be greater than calculated loads for standby purposes. Standby equipment must be automatically controlled to be off when the primary equipment and/or system is operating. -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. 2.Each heating or cooling system serving a single zone must have its own temperature control device. 3.Each humidification system must have its own humidity control device. 4.Design heating and cooling loads for the building must be determined using procedures in the ASHRAE Handbook of Fundamentals or an approved equivalent calculation procedure. 5.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°F during heating and setting up to 85°F during cooling, b) capable of automatically setting back or shutting down systems during unoccupied hours using 7 different day schedules, c) have an accessible 2-hour occupant override, d) have a battery back-up capable of maintaining programmed settings for at least 10 hours without power. Exception(s): -A setback or shutoff control is not required on thermostats that control systems serving areas that operate continuously. -A setback or shutoff control is not required on systems with total energy demand of 2 kW (6,826 Btu/h) or less. 6.The system must supply outside ventilation air as required by Chapter 4 of the International Mechanical Code. If the ventilation system is designed to supply outdoor-air quantities exceeding minimum required levels, the system must be capable of reducing outdoor-air flow to the minimum required levels. 7.All pipes serving space-conditioning systems must be insulated as follows: Hot water piping for heating systems: 1 1/2 in. for pipes <=1 1/2-in. nominal diameter, 2 in. for pipes >1 1/2-in. nominal diameter. Chilled water, refrigerant, and brine piping systems: 1 1/2 in. insulation for pipes <=1 1/2-in. nominal diameter, 1 1/2 in. insulation for pipes >1 1/2-in. nominal diameter. Steam piping: 1 1/2 in. insulation for pipes <=1 1/2-in. nominal diameter, 3 in. insulation for pipes >1 1/2-in. nominal diameter. Exception(s): -Pipe insulation is not required for factory-installed piping within HVAC equipment. -Pipe insulation is not required for piping that conveys fluids having a design operating temperature range between 55°F and 105°F. -Pipe insulation is not required for piping that conveys fluids that have not been heated or cooled through the use of fossil fuels or electric power. -Piping within room fan-coil (with AHRI440 rating) and unit ventilators (with AHRI840 rating).

Exception(s): -Systems with heat recovery. -Multiple-zone systems without DDC of individual zones communicating with a central control panel. -Systems with a design outdoor airflow less than 1200 cfm. -Spaces where the supply airflow rate minus any makeup or outgoing transfer air requirement is less than 1200 cfm. 10.All freeze protection systems, including self-regulating heat tracing, must include automatic controls capable of shutting off the systems when outside air temperatures are above 40°F or when the conditions of the protected fluid will prevent freezing. Snow- and ice-melting systems must include automatic controls capable of shutting off the systems when the pavement temperature is above 50°F and no precipitation is falling, and an automatic or manual control that will allow shutoff when the outdoor temperature is above 40°F. 11.Individual fan systems with a design supply air capacity of 5000 cfm or greater and minimum outside air supply of 70 percent or greater of the supply air capacity must have an energy recovery system with at least a 50 percent effectiveness.
