disagreeable glare. Pulpits and other foci of action should be lighted from
two sources, 60 to 90 degrees apart and of somewhat varied intensity. The use
of multi-circuit light-tracks and other devices that provide a very generous
flexibility is commended partly because they can provide for theatrical events
of some kinds. Dimmers should be supplied; controls should be near the main
entrance unless there is a control booth. Location of special lighting
instruments should be such that they can be easily and quickly adjusted or
changed.
(3) Chaplains' Offices. Incandescent lighting renders color
properly, supplies lively highlights and shadows, and conforms comfortably to
domestic character. All these qualities support the humane kind of environment
that helps chaplains serve personnel that come to them for aid. No ceiling
lamps are needed in these rooms; task lighting should be exploited.
(4) Social Halls. As in other rooms where an atmosphere of
congeniality and hospitality are premium qualities, incandescent light on a
dimmer system is appropriate for social halls. Because the use ,of these rooms
varies, incandescent levels of 20 to 25 footcandles should be supplemented
with separately switched fluorescent lamps to bring the levels up to 35 to 40
footcandles.
(5) Exterior Lighting. The evidence of hospitality needs to appear
in exterior lighting of the facilities. Provision should be made for lighting
special seasonal displays as well as permanent exterior features.

MECHANICAL SYSTEMS.
a.
HVAC. Requirements for heating, ventilating and cooling conform
generally to NAVFAC DM-3.3, Heating, Ventilating, Air Conditioning and
Dehumidifying Systems. Comments relating to preventing sound transmission
through mechanical systems have been noted in Section 4.1, Acoustical
Qualities. See page 37.06-28.
The anticipated operating schedule must be considered in all energy
analysis supplied for the design of the project. Separate air conditioning
units may be used for areas of diverse occupancy if the study supports this.
Energy storage systems may be proposed because of short duration of some
loads, and full cooling of all areas may not be effective when considering the
energy used.
b.
Plumbing. NAVFAC DM-3.1. Plumbing Systems, applies except
for three supplementary details:
(1) A Sacrarium. This is a small sink for the disposal of
sacramental liquids directly to the ground. The sink needs a cover,
