Page 12 5.1.1 Indirect Lighting Indirect lighting uses fluorescent or metal halide lamps to up light a light color ceiling; the resulting reflected light is inherently very soft, shadow-free, and low-glare. Indirect lighting works well for both paper-based and computer tasks in rooms where the ceiling height is at least 9'-6" and preferably more than 10'-0". 5.1.2 Direct Lighting Direct lighting uses down lights to illuminate the reading tables. The down lights can be as small

Page 5 lamps have a bluish-white color; some librarians prefer this color, especially <span class="highlight">in</span> desert climates, where the cool color of <span class="highlight">light</span> may psychologically imply a cool relief from the hot exterior environment. It should be noted that the choice of lamp color has no effect <span class="highlight">on</span> <span class="highlight">light</span> levels or cost - it is basically an aesthetic choice. Regardless of which color is selected, the <span class="highlight">light</span> spectrum from standard fluorescent lamps provides adequate color <span class="highlight">rendering</span> for the visual tasks <span class="highlight">in</span>

Page 10 Some designers try to combine the parallel and perpendicular schemes into a diagonal arrangement of rows, but this offers no <span class="highlight">real</span> advantages and creates a visually distracting layout that is hard to coordinate with the ceiling structure. 4.2.3 Indirect Scheme The indirect scheme uses up lights <span class="highlight">on</span> top of the stacks or suspended from the ceiling. All of the <span class="highlight">light</span> is reflected off the ceiling, so the illumination <span class="highlight">on</span> the stacks is very <span class="highlight">soft</span>, and the entire range of stacks appears

of view. • Variation control, to avoid any user perception of insufficient local light levels. Daylight apertures in walls and roofs are essentially in situ light fixtures using renewable light energy from the sun. The building design team must not only address the three principal issues above for a variable, heat-laden source, but must configure the daylight apertures to reflect and diffuse the light effectively to serve the lighting tasks appropriately. Daylighting solutions that address the above
