to minimize condensation and resulting corrosion. Documentation of the installation instructions must be provided to be exempted from
this requirement.
4.Systems designed to maintain usage temperatures in hot water pipes, such as recirculating hot water systems or heat trace, must
be equipped with automatic time switches or other controls that can be set to switch off the temperature maintenance system during

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: 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.
-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.

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.

3 in. insulation for pipes >1 1/2-in. nominal diameter.
-Exception: Pipe insulation is not required for factory-installed piping within HVAC equipment.
-Exception: Pipe insulation is not required for piping that conveys fluids having a design operating temperature range between 55°F
and 105°F.
-Exception: 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.
-Exception: Piping within room fan-coil (with AHRI440 rating) and unit ventilators (with AHRI840 rating).
-Exception: Pipe insulation is not required for runout piping not exceeding 4 ft in length and 1 in. in diameter between the control valve
and HVAC coil.
11.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 actions
b) equipment operation and maintenance manuals
c) HVAC 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 comments
d) complete narrative of how each system is intended to operate.
12.Service hot water piping, where required, must be insulated to 1/2 in. if pipe less than 1.5 in. nominal diameter. Larger pipe must be
insulated to 1 in.. Pipe insulation will have a conductivity of less than 0.28 Btu.in/(h-ft2-°F).
13.Temperature controlling means must be provided to limit the maximum temperature of water delivered from lavatory faucets in public
facility restrooms to 110°F.
14.Thermostats controlling both heating and cooling must be capable of maintaining a 5°F deadband (a range of temperature where no
heating or cooling is provided).
-Exception: Deadband capability is not required if the thermostat does not have automatic changeover capability between heating and
cooling.
-Exception: Special occupancy or special applications where wide temperature ranges are not acceptable and are approved by the
authority having jurisdiction.
15.Balancing devices provided in accordance with IMC (2006) 603.17.
16.Demand control ventilation (DCV) required for high design occupancy areas (>40 person/1000 ft2 in spaces >500 ft2) and served by
systems with any one of 1) an air-side economizer, 2) automatic modulating control of the outdoor air damper, or 3) a design outdoor
airflow greater than 3000 cfm.
-Exception: Systems with heat recovery.
-Exception: Multiple-zone systems without DDC of individual zones communicating with a central control panel.
-Exception: Systems with a design outdoor airflow less than 1200 cfm.
-Exception: Spaces where the supply airflow rate minus any makeup or outgoing transfer air requirement is less than 1200 cfm.
17.Outdoor air supply and exhaust systems must have motorized dampers that automatically shut when the systems or spaces served are
not in use. Dampers must be capable of automatically shutting off during preoccupancy building warm-up, cool-down, and setback,

except when ventilation reduces energy costs (e.g., night purge) or when ventilation must be supplied to meet code requirements. Both
outdoor air supply and exhaust air dampers must have a maximum leakage rate of 3 cfm/ft2 at 1.0 in w.g. when tested in accordance
with AMCA Standard 500.
-Exception: Gravity (non-motorized) dampers are acceptable in buildings less than three stories in height.
-Exception: Systems with a design outside air intake or exhaust capacity of 300 cfm (140 L/s) or less that are equipped with motor
operated dampers that open and close when the unit is energized and de-energized, respectively.
18.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.
19.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. Where cooling with outdoor air
is required there is a means to bypass or control the energy recovery system to permit cooling with outdoor air.
-Exception: Hazardous exhaust systems, commercial kitchen and clothes dryer exhaust systems that the International Mechanical
Code prohibits the use of energy recovery systems.
-Exception: Systems serving spaces that are heated and not cooled to less than 60°F.
-Exception: Where more than 60 percent of the outdoor heating energy is provided from site-recovered or site solar energy.

-Exception: Laboratory fume hood exhaust systems that have either a variable air volume system capable of reducing exhaust and
makeup air volume to 50 percent or less of design values or, a separate make up air supply meeting the following makeup air
requirements: a) at least 75 percent of exhaust flow rate, b) heated to no more than 2°F below room setpoint temperature, c) cooled
to no lower than 3°F above room setpoint temperature, d) no humidification added, e) no simultaneous heating and cooling.
