F-8.4
Considerations for Incandescent, HID, or Compact Fluorescent Lamps.
F-8.4.1 Downlights are a common lighting system for illumination of lobbies, corridors,
and many other space types. In most applicati ons, compact fluorescent or HID lamps
should be used, but in some cases, such as residences and dining rooms, incandescent
lamps can be used, subject to approval by the Authority Having Jurisdiction. Related
types include wallwashers and accent lights.
F-8.4.2 Luminaires that are mounted in exterior and some interior applications are
often selected for resistance to physical damage as well as long term durability. Vandal
resistant designs are also used in utility areas for protection against breaking.
F-8.4.3 Vaportight luminaires, also called jelly jars, are commonly used in a variety of
industrial and commercial utility applications. Compact fluorescent and HID lamps
make these luminaires efficient choices in a number of applications.
F-8.4.4 Track lighting is a versatile lighting system especially effective for retail
display lighting, museum and gallery lighting, and other situations where spotlighting of
objects is desired. In some cases, track can be used for general lighting because it is
easily installed from a single electric feed point.
F-9
APPEARANCE AND AESTHETICS.
F-9.1
Evaluate the importance of lighting appearance and aesthetics for each space
being designed. As a minimum, utilize luminaires intended for the application and in an
appropriate manner consistent with the manufacturer's recommendations.
F-9.2
When called for in the selection of a specific luminaire, include consideration
for the appearance of the luminaire (including surface brightness), the quality of the
luminaire, a nd the resulting lighting appearance.
F-10
COST EFFECTIVENESS.
F-10.1
Life cycle cost methods are required for Federal projects to the extent that
these measures minimize life cycle costs and are cost effective. Standardized
assumptions must be used, i ncluding discount rates, energy inflation, and analysis
period. This process is described in the Life Cycle Costing Manual (NIST Handbook
135), and its Annual Supplements, available from the National Institute of Standards
and Technology (NIST) at www.nist.gov.
F-10.2
Federal life cycle costing is based on discounting all costs back to their
present value. All of these costs are then summed. The summed present value of all
costs for different projects can then be compared. The Federal Energy Management
Program also requires that alternative projects be ranked by their savings to investment
ratio.
