for][central building exhaust systems for] general exhaust systems. Provide individual
thermostatically controlled exhaust fans for mechanical/electrical rooms and other spaces
where ventilation only is required.

INCREMENTAL EQUIPMENT. The following equipment will be acceptable for the
facilities on this project except where noted otherwise for specific buildings. Minimum equipment
efficiencies shall be in accordance with DOE Buying Energy Efficient Products
Recommendations (refer to www.eren.doe.gov/femp/procurement for recommended
efficiencies) or Energy Star.
10-5.1
Packaged air conditioning units. Unit shall be a through-the-wall mounted, heavy-
duty commercial grade, factory assembled and precharged air-conditioner [heat pump] unit.
Unit shall be in accordance with ARI 310/380 and UL 1995. Units shall be removable from
inside the building for servicing without removing the outside cabinet. Louver shall be
stormproof type, constructed of anodized, stamped or extruded aluminum. Controls shall include
an on-off switch, multiple speed fan mode and an adjustable [cooling and] heating thermostat.
Function and temperature controls shall be [integral to unit][remote mounted].
10-5.2
Air-to-air heat pump units. Unit shall be a through-the-wall mounted, heavy-duty
commercial grade, factory assembled and precharged heat pump unit. Unit shall be in
accordance with ARI 310/380 and UL 1995. Units shall be removable from inside the building
for servicing without removing the outside cabinet. Louver shall be stormproof type, constructed
of anodized, stamped or extruded aluminum. Sleeve shall be a water and airtight [completely
insulated] [noninsulated] assembly, with weather-resistant protective coating. Units shall contain
a reversing valve to change unit to heating cycle. An outdoor coil temperature sensor shall be
provided to guard against coil freeze-up by either switching to supplemental heat only, or by
cycling the compressor to defrost the coil. Controls shall include an on-off switch, multiple speed
fan mode and an adjustable [cooling and] heating thermostat. Function and temperature
controls shall be [integral to unit][remote mounted].
10-5.3
Water source heat pumps. Units shall be horizontal or vertical type with easily
accessible filters. Controls shall include an on-off switch, multiple speed fan mode and an
adjustable [cooling and] heating thermostat.
10-5.4
Evaporative coolers. [Evaporative coolers shall be considered only at installations
which traditionally use evaporative cooling, and comfort conditions can be maintained through
their use. Determine whether evaporative coolers will be allowed as a design option to the
offeror.] Units shall be self-contained, single stage, weather- resistant type, and shall conform
to UL 507 and UL 746C. The fan shall be centrifugal type and shall be complete with motor,
drive equipment, and vibration-isolation supports between motor and fan housing on single
phase motors. Water distributor or rotary wheel motor shall be provided with a time delay in the
fan circuit to allow media to be thoroughly wetted before air flow starts. Manual or automatic
reset type thermal overload protection shall be provided. Evaporative cooler fans shall have air
delivery ratings based on AMCA 210 tests by an AMCA approved laboratory. An ultraviolet
retarding agent shall be part of or applied on exterior nonmetallic components susceptible to
ultraviolet degradation from sun rays and conforming to UL 746C. Evaporative media shall be
specifically manufactured for use with evaporative coolers. Media shall be honeycombed type,
fabricated such that no moisture entrainment shall occur. Face velocities shall be limited to
those recommended by media manufacturer. Indirect coolers shall consist of an air-to-air heat
exchanger, water distribution header, scavenger fan and motor, recirculating water pump,
