Building Envelope:
The building is steel frame construction on poured-in-place
concrete foundations, with slab on grade. The exterior is a
combination of integral aggregate tilt-up concrete masonry
veneer, with punched openings and curtain wall. The
glazing systems are tinted with high performance low-e
glazing in clear anodized aluminum frames. The roof is a
sloped concrete deck with a membrane roofing system,
decorative edge treatments, and mechanical equipment
screens.

Exterior Façade
Spatial Overview
The parking lot consists of 220 regular spaces and 10 handicap spaces. There are
sidewalks leading from the parking lot to the building. There is an ornamental concrete
sidewalk at the two main entrances that uses a second color of concrete. The building
façade is made up of tilt-up poured in place concrete. About every 32’ there are
aluminum half-round columns with 12”x12” tile accent above them on the façade.
Performance Considerations
The main performance of the outdoor lighting is to provide enough light to safely
see while walking to and from the building. Light pollution is a major concern due to the
Page 7

fact that the building is along a major road and under the landing paths for two airports.
So, selecting luminaries that have the correct cutoff angles are necessary. Lighting the
columns and overhangs tied in with the glowing lobby would make this an attractive
building at night.
Design Concept
My design concept for the outdoor area is to provide a visually appealing space
that draws attention. The entrances, columns, awning, and tiles are the main attractions
and need to stand out from the rest of the walls. The awning needs to be up-lit to create a
glowing top. The columns and cladding to the sides of need to be highlighted without the
excess light spilling out on to the concrete portion of the wall to the sides of the column.
The awning has to be highlighted by lighting the ground below the awning, highlighting
the wall above, and making the glass canopy glowing

Lobby
Spatial Overview
The lobby is the first interior feature in the building. It is in the center of the
building and can be entered from both the north and south sides of the building. This two
story space incorporates the first and second floor elevator lobbies. There is a main lobby
desk with a two story mural of the history of the Michael baker corporation. The space is
24’ from floor to ceiling.
Performance Considerations
The lobby is a circulation area in which everyone enters the building. Tasks such
as reading and writing do not apply accept at the lobby desk. The best way to achieve
this is most likely using task lighting on the desk surface. This will reduce direct glare
from the secretary, while providing adequate light levels. Highlighting the locations of
the elevators, stairwells, and interior door is necessary to assist with circulation through
the space.
Design Concept
The idea for this space is to create an attractive first interior space and highlight
paths to more interior areas of the building. There needs to be enough light to allow the
secretary to complete its job. Also, an attractive way to highlight the double height mural
on the wall behind the secretary is necessary. Utilizing sconces will make an easy and
attractive way to highlight the elevators.

Presentation Space
Spatial Overview
This highly finished space is used for presentations, all forms of conferencing,
and training sessions. This room with utilizes many pieces of high tech presentation and
conferencing equipment that are necessary for the space. There are windows to the
outside lining the exterior wall. One of the interior walls is lined with glass.
Performance Considerations
Do to the versatile nature of this room multiple lighting conditions are necessary
in this space. When used as standard conference room lighting for tasks such as reading
and writing need to be considered. When using the projector, Plasma Television, or
iBoard a way to completely keep light off these screens must be employed. Facial
shadowing is an important factor for any type of presentation or conference setting. The
mobility of the podium to the front or back requires its own lighting. If in the back task
lighting should be enough, yet in the front the speaker also must receive light for good
facial rendering. Glare is needed to be taken into consideration do to the high gloss table
and plasma TV.
Design Concept
In this space there are three main types of light that will need to be taken into
consideration within this space which are: key light, fill light, and background light. I
plan on completing this by using layered light and zone/scene controls to optimize the
room for multipurpose use. Also, I plan on using a zero light shading system to remove
visual distractions and light from the outside the room.

Open Office
Spatial Overview
The office space covers almost the entire second floor. The space is covered with
clusters of eight cubicles. The cubicle heights are 6’ with 18” of glass along the top to
allow exterior views form almost anywhere on the floor. Evenly spaced windows line the
north and south walls with corner windows from floor to ceiling, to allow daylight into
the space throughout the day. Each cubicle has a computer station. Paintings and past
project boards line the interior walls.
Performance Considerations
An open office space’s most important job is to increase worker output. To do
this maximizing worker comfort is a major concern. A ways to accomplish this include
the following: glare reduction, veiling reflections light distribution uniformity, and
daylight integration and viewing. Do to the massive amount of computer work
completed in this space glare is a major issue. Light distribution needs to have a
uniformity of 3:1 within the space. This not only helps comfort but allows even lighting
even if the cubicle arrangement changes. Task Lighting is also a necessary component to
the space.
Design Concept
The lighting design of the office will incorporate enlarged windows for a more
comfortable feel and increased day lighting. To reduce glare from these windows I
propose using manual shades. The lighting system has two components, ambient and
task lighting. The ambient system will be suspended indirect/direct fixtures in linear
runs, mounted 2’ from the ceiling. These will provide illuminance levels around 30-40fc
on the work plane, while keeping a moderately uniform luminance distribution along the
ceiling. The 3 rows of fixtures along the north and south walls, utilize daylight sensors to
reduce power consumption throughout the day do to the enlarged windows. The task
lighting system incorporates a LED swivel arm and an under cabinet linear fluorescent
fixtures.

Daylighting
A daylight study of this space is very important due to the enlarged windows I
designed for this space. The light enters the space from north and south facing walls.
From my analysis I was able to determine daylight would play an integral role within the
space do to the enlarged windows. The following study shows the space at 12PM on
December 21, March 21, and June 21, with both clear sky and overcast sky.

Daylight Integration
Based on my results from I my daylight study I created a daylight integration plan
utilizing SPOT software. With this program I was able to zone the fixtures and find
placement of daylight sensors for optimum power reduction. Also I was able to estimate
the daytime monthly energy savings by using dimmed fixtures with integral daylight
sensors. For full SPOT analysis see Appendix A
Figure 54: SPOT daylighting and daylight sensor images

Which according to spot will result in savings of $5,725 a month.
Controls
Multi-Way switches are spread throughout the room for accessible lighting
control. To go along with the occupancy sensors, Daylight sensors, and an automatic
time based programmable remote control system that turns all lights on at around 7:00
AM and turns them off around 7:00 PM.

LED Series
Dazor’s high power LED desk lamps represent an outstanding improvement over other
LED powered lamps on the market. Our use of advanced technology coats the core
boards with a ceramic material that naturally dissipates the heat so no noisy and irritating
fans are needed. Further, the light pattern from Dazor’s LED luminaire is diffuse and
color consistent and UV wavelength has been eliminated from the LED light spectrum.
The phosphorous coating used in the powerful 1-watt LEDs produces a single, white
light. No striping, patterns of illumination “blotches,” nor color distortion are present in
the pattern of illumination.
The LED desk lamps come mounted on Dazor’s patented floating arm with either a
clamp or weighted desk base as well as a Flex Arm model with a clamp base.

High Power LED Lighting
LED technology has recently advanced to a stage that it is
now a viable and reliable illumination option to other
forms of lighting commonly used in task lights. Today’s
High Power LEDs produce accurate and consistent colors
of white light without ultraviolet or infrared wavelengths.
They are also endorsed by government and private
research institutions because of the significant energy,
maintenance, and environmental benefits they provide.
Dazor is now helping to bring this technology from
research and development into commercialization with its introduction of our new line of
LED powered task lights. Why choose LED?
Increased Light Output / No Glare
Traditional illumination sources like fluorescent, incandescent, and halogen are omnidirectional; that is, they emit light in all directions. Illumination from these lamps must be
re-directed toward the work surface using reflectors in the fixture. However, each time
illumination is reflected, a certain amount gets lost. Some of the light gets trapped behind
the lamps and never gets out of the fixture, while other light makes its unwanted way into
a person’s eyes in the form of glare. Depending on fixture design, up to half the light
generated by an omni-directional illumination source may not make it to the desired work
surface location.
The light emitted from an LED is directional. The directed nature of LEDs can result in
up to 95% of the illumination ending up at the desired point on the work surface.
Therefore, with a properly designed LED fixture, less total light output is required to
provide the same level of illumination at the desired location.

Figure 1 compares the lumen density from a standard 5mm white LED to a High Power
white LED. The High Power LED delivers 5X the lumen density of a standard 5mm
LED.
Longer Life
Because fluorescent and incandescent illumination sources use filaments in their design,
the end of life for these technologies typically occurs with a total failure of the bulb. In
fact, the average rated life for a typical incandescent bulb is 1,800 hrs while fluorescent
bulbs average about 7,500 hrs.
LED technology, on the other hand, does not allow for the LED source to catastrophically
fail. Rather, the amount of light output simply decreases over time and this can be
minimized through proper packaging design, power regulation, and thermal management.
Light output from High Power LEDs depreciates negligibly over time giving them a full
service life of over 50,000 hours without any color degradation. There is no point in time
at which the light source stops functioning.

Improved Color Quality and Consistency
Dazor has combined state-of-the-art High Power LEDs and an innovative thermal system
design within its unique fixturing, which substantially minimizes any color variation in
white light over the product life. In Dazor’s LED fixtures, there is no need for secondary
devices to dissipate heat, such as irritating cooling fans or pipes.
To ensure color consistency, LED manufacturers use specialized automated optical
measurement equipment to test each individual LED. After optical testing, each
individual LED is sorted and stored according to its specific color temperature bin as well
as its flux (light output) and forward voltage (electrical). This classification process
allows Dazor to select the proper LEDs for devising task lights that produce the desired
illumination properties for specific applications.
Reduced Energy Consumption
Today’s High Power LED’s consume 1 watt of electricity (higher wattage LEDs are in
development and even available in certain commercial applications). Traditional
measurement of light efficiency is known as “luminous efficacy”, which measures how
much light output (lumens) a light source emits in comparison to how much energy it
consumes (watts of electricity). The luminous efficacy of a light source is quantified in
“lumens per watt”.
Luminous efficacy is an important indicator of light efficiency, but it doesn’t tell the
whole story, particularly with regard to High Power LED light sources.
Due to the directional nature of their light emission, LEDs potentially have higher
application efficiency than other light sources because more of the light output from an
LED actually hits the target it is intended to illuminate.

In addition to requiring less energy to power an LED than traditional light sources, LEDs
have other environmentally friendly characteristics. They contain no mercury or gas and
emit no infrared or ultraviolet radiation. Also, most High Power LEDs are lead-free and
RoHS compliant.
No UV and No IR
LEDs present very real and unique illumination opportunities that are new and relevant to
the world. At no other point in history has an unfiltered illumination source been
available that is intrinsically devoid of infrared and ultraviolet wavelengths from the light
beam within the commonly used range of white colors. This creates interesting
challenges and opens doors for development of new LED light fixtures designed for use
in applications where color correct light output is critical to the visual task.
Reduced Glare & Hot Spots
Not only do High Power LEDs emit directional light, but Dazor LED light fixtures and
desk lamps use secondary optics to further control the direction of the light output onto
the desired work area. This technology allows for the diffusion of the directional light in
a controlled manner, eliminating “hot spots” on the work surface and also eliminating
glare. In doing so, LED desk lamps reduce the fatigue effects that occur during everyday
work that are commonly associated with the omni-directional lighting produced by
fluorescent and incandescent lights.
High Vibration Resistance
High Power LEDs (solid-state devices) have no moving parts, no filament, and no fragile
glass shell. This represents a considerable practical improvement to luminaries which
house traditional glass bulbs. The likelihood of bulb breakage occurring during the
shipment of light fixtures and desk lamps can be substantial due to the quality of fixture
packaging, in combination with the commercial means commonly available to transport
and distribute light fixtures and desk lamps. The risk of bulb breakage is virtually
eliminated with LED solid-state devices.
Dimmable and Instant “Startability”
LEDs are infinitely dimmable without sacrificing any characteristic of the light. There is
no deterioration of color when the light fixture and drive electronics are properly
designed, despite declining light intensity. In addition, LEDs start instantly and emit full
color and light intensity at a temperature as low as -40C.

Better Thermal Management
Traditional illumination sources dissipate heat forward by emission of infrared radiation
(IR) wavelengths and through conduction or convection of heat by design of the fixture.
Conversely, High Power LED technology requires all heat from LEDs be conducted
away from the LED chip. So while, the forward light path emitted from a halogen or
incandescent bulb is hot, LED radiates negligible IR so there is no heat in the light path.
Any heat generated when the LED is illuminated is conducted back through the board, its
fixture, and ultimately dissipated into the surrounding atmosphere.
Dazor’s light fixture design uses High Power LEDs that incorporate a separate heat sink
into their packaging, which dramatically improves heat transfer between the blue light
emitting surface (the “chip” or “die”) and the electronic mounting board. In addition, the
drive electronics are specially engineered to control the amount of electric current input
at critical thermal junction points. Engineering the total light fixture package with proper
thermal design as a primary consideration allows Dazor to use a higher electrical current
to drive the LEDs. This thermal design and heat management system increases light
output while protecting LED color consistency and life of operation.
In Conclusion…
Today’s LED High Power LED technology can be used as a viable, cost effective, color
accurate, lighting alternative to traditional illumination sources. Unique characteristics of
LEDs allow this technology to not only be a basic source of illumination, but also to be
the light source of choice in many task applications where visual precision is needed.
