4. 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).
5. Temperature controlling means must be provided to limit the maximum temperature of water delivered from lavatory faucets in public
facility restrooms to 110°F.
6. Thermostats controlling both heating and cooling must be capable of maintaining a 50F 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.
7. 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.
8. Where zone heating and cooling are controlled by separate zone thermostats, means (such as limit switches, mechanical stops, or, for
DDC systems, software programming) must be provided to prevent simultaneous heating and cooling to the zone.
9. Stair and elevator shaft vents must be equipped with motorized dampers capable of being automatically closed during normal building
operation and interlocked to open as required by fire and smoke detection systems. All gravity outdoor air supply and exhaust hoods,
vents, and ventilators must be equipped with motorized dampers that willautomatically shut when the spaces served are not in use.
Exception: Ventilation systems serving unconditioned spaces.
Exception: Gravity (non -motorized) dampers are acceptable in buildings less than three stories in height above grade.
10. Where a zone is served by a system(s) with both humidification and dehumidification capability, means (such as limit switches,
mechanical stops, or software programming) must be provided to prevent simultaneous operation of humidification and dehumidification
equipment.
- Exception: Zones served by desiccant systems, used with direct evaporative cooling in series; Systems serving zones where specific
humidity levels are required.
11. 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.
12. Duct and pipe insulation exposed to weather must be suitable for outdoor service; e.g., protected by aluminum, sheet metal, painted
canvas, or plastic cover. Cellular foam insulation must be protected as above or painted with a coating that is water retardant and
provides shielding from solar radiation that can cause degradation of the material. Insulation covering chilled water piping, refrigerant
suction piping, or cooling ducts located outside the conditioned space must include a vapor retardant located outside the insulation
(unless the insulation is inherently vapor retardant), all penetrations and joints of which must be sealed.
13. Duct Sealing Requirements:
a) Pressure sensitive tape used as the primary sealant is certified to comply with UL-181 A or UL-181 B,
b) Longitudinal and transverse seams for ducts in unconditioned spaces,
c) Longitudinal and transverse seams and duct wall penetrations for ducts outside the building,
d) Transverse seams on buried ducts
14. 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 10(motorized)/20(non-motorized) 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 Us) or less.
15. All supply and return ducts and plenum installed as part of an HVAC air distribution system must be thermally insulated:
R-6 for supply air ducts located outside the building, in ventilated attics and in unvented attic above insulated ceiling,
R-1.9 for supply air ducts in unvented attic with roof insulation,
R-3.5 for supply air duct insulation in unconditioned and underground spaces,
R-3.5 for return air ducts located outside the building, in ventilated attics and in urivented attic above insulated ceiling.
16. Where humidistatic controls are provided, such controls must prevent reheating, mixing of hot and cold air streams, or other means of
simultaneous heating and cooling of the same air stream.
