17. BOILER PLANT OR ENERGY CENTER BUILDING:
17.1 Building arrangement:
17.1.1 Provide a structural system which permits access to overhead members
for pipe and duct support and allows for future expansion.
17.1.2 The building design shall permit all equipment to be installed (and
removed in the future) without removal of any building structural element,
walls or the roof.
17.1.3 Locate the main boiler room or energy center floor above finished grade
to preclude flooding and to permit horizontal rigging of equipment in and out
of the building.
17.1.4 Establish roof height to provide adequate clearance above all equipment
and piping. Provide for present or future installation of economizers above
the boilers.
17.1.5 Provide basement area or pit areas for underground steam distribution
pipe entrance and blow-off tank.
17.1.6 Provide basement area, if necessary for proper operation, for
condensate storage tank, condensate transfer pumps, and fuel oil pumps.
17.1.7 Locate a mezzanine above the boiler feed pump area to support and
provide access to the deaerating feedwater heater. Normal mezzanine floor
height above the boiler room floor is 3.7 meters (12 feet). Design the
mezzanine floor to contain water spillage.
17.1.8 Provide overhead roll-up doors through which all equipment can be
rigged. Locate a roll-up security grill inside each door so that the doors
can be open for summer ventilation.
17.1.9 The building and site adjacent to the building shall be arranged to
allow for future expansion if additional boilers, chillers, or other equipment
are needed.
17.1.10 Provide a block wall partition between the chiller portion of the
building and other areas for noise control. Also provide the same for the co-
generation engine unless other noise reduction measures are taken.
17.2 Provide the following personnel facilities:
17.2.1 An air conditioned control
room of at least 14 square meters (l50
square feet) floor area with view
windows located to allow observation of
firing aisle and chillers. Where
an Engineering Control Center is provided
additional floor area is required
(see Chapter 230 of VA Handbook 7610 for
required floor area).
17.2.2 A supervisors' office of approximately 10 square meters (100 square
feet) floor area.
17.2.3 Locker facilities on the main floor of boiler plants and energy centers
for employees, one or more of whom may be female. Facilities shall include
separate showers and locker rooms for male and female employees. Twelve
lockers shall be provided including a minimum of two lockers in the female
locker area.
17.2.4 Two separate toilet rooms adjacent to the locker rooms each having a
water closet and lavatory plus a urinal in male toilet.
