Lighting
Design Considerations:
Natural daylighting- Daylighting should be incorporated wherever
possible as it will increase the quality of the indoor environment and reduce lighting
loads. People have a biological need to see natural daylight. Diffused natural
light utilized with pale reflecting materials and supporting systems will result in an
optimal lighting design.
Artificial Lighting- Use T-8 tubular fluorescent lamps which are much
more efficient, accurate, and pleasant in color. Use sodium lamps to reduce the
amount of energy consumption. CFLs- compact fluorescent lamps- use one quarter as
much electricity and last ten times longer than incandescents, are dimmable and available
in many sizes, shapes and wattages.
Lamp disposal is hazardous waste- even in miniscule amounts, mercury can be highly
toxic.
Dispose of lamps in EPA-approved MSW and the generator needs to keep records for at
least three years of where the lamps were sent.
Utilize long-life fluorescent bulbs that are energy efficient
Photosensoring devices- Photosensoring devices can be used
to detect natural light levels, then trigger appropriate levels of supplemental artificial
lighting.
Smart lighting automatically adjusts to the desirable level of lighting that is
desired.
Circuiting and Switching -Separate circuiting and switching should be
provided for different tasks and zones. Light controls should be easily accessible
so that occupants can readily make lighting adjustments.
Occupancy Sensors -Utilize occupancy sensors throughout building to
conserve energy when spaces are unoccupied for more than five minutes.
Interior windows -Incorporate interior windows into enclosed spaces in
order to maximize the amount of daylighting
Interior paint colors and finish textures- Ceilings and walls should
be painted with a high reflectance, non-toxic paint to maximize light quality
