Exciting Changes in the Lighting Industry

WLS Lighting Systems

• Whitco, the parent company of WLS Lighting
  Systems, was founded in Fort Worth, TX. In 1969
  Mr. Jim Pritchard began developing the company
  into an Internationally known pole manufacturing
  facility.
• As retail shopping centers evolved in the early
  70s Whitco developed a working relationship with
  Kmart, one of the nations first big box
  retailers, providing complete lighting packages,
  both interior and exterior.
• Dean Pritchard attended his first ICSC Las Vegas
  conference in 1981. WLS has lighted 1000s of
  shopping centers and is recognized as one of the
  leaders in the lighting industry.

Session Objectives
Trends in lighting today. Typical light levels
of retailers. Parameters for identifying
relighting opportunities. Good maintenance of
your existing lighting. The financial, global,
and customer benefits of lighting.

The World of Lamps
FLUORESCENT (1939)
HID.High Intensity Discharge
? Mercury Vapor (1930s) ? High Pressure Sodium
(1964) ? Metal Halide (1966)

Trends

• Government / Municipal Energy Efficiency
  Mandates
• LEED Certified Projects
• 2007 EISA Pulse Start MH Requirement -
  Beginning 09
• Tenant Lighting Criteria Not Changing
  (no decrease)
• More Stringent Local Lighting Criteria
  (lower levels/dark sky)
• Decrease In New Construction
• Increased Interaction Between
  Departments
• Better Maintenance Programs
• New Technology
• More Product Offerings
• Energy Efficient Products
• Group Re-lamp Programs
• Controls / Energy Management

Tenant Lighting Requirements

• Wal-mart requires a minimum of 2.0 foot-candles
• Best Buy - 7.0  foot-candle average equals
  approximately 3.0 minimum foot-candles
• Target-5.0 minimum foot-candles at the store
  front and  at least 2.0 in the main lot
• Kohl's - 5.0 foot-candle average, 2.0 minimum
  foot-candles,  5.0 minimum at entrance
• Drug Stores - require 2-3 minimum foot-candles
• Grocers - minimum of 3.0 foot-candles and many
  want a minimum of 5.0 footcandles
• Malls - 2.0 minimum foot-candles

8
WLS Recommendations

• Maintain  2.5 to 3.0 minimum foot-candles
  throughout the main lot with no less than 1.5 to
  2.0  at the perimeter
• Minimum pole height of 30' (when permitted) not
  exceeding 40'
• 1000, 775, or 750 watt pulse start vertical lamp
  metal halide fixtures
• Minimum of .5 in the rear of the building using
  400  or 250  watt wall mounted fixtures 
  depending on mounting height 
• Use poles in the rear when .5 cannot be obtained
  with only wall mounted fixtures or the store is
  located where more security is required
• Floodlight store fronts

Site Lighting Management

• Group Relamping
• Control Systems
• RetrofittingIdentifying Potential Projects

10
Group Relamping

• Less than 3 of Developers and Retailers group
  relamp
• Most properties are HALF as bright as originally
  designed
• Good site lighting increases night time sales
• Group relamping VS. Spot relamping...cheaper in
  the long run!
• Why pay 100 of the energy bill for 50 of the
  light?
• Excellent ROI

11
Site Control Systems

• Existing systems are outdated Photocell / Time
  Clocks
• Trends
• Astronomical time clocks
• Wireless control systems
• 2-way communicationvia. email, cell, PDA, WEB,
  etc.
• Smart control systemsalerts, rotate lamps,
  load shedding
• Controls irrigation, signage, fountains,
  security cameras
• Dramatically reduces energy consumption

12
RetrofittingIdentifying Potential Projects
After retrofitting our poorly lit center, our
night time sales increase 30
Randy Benderson
By retrofitting you increase sales, image, curb
appeal, safety, and keep up with the competition.

• Horizontal lamped fixtures
• High Pressure Sodium (HPS) lamps
• Poles spaced more than 5 mounting height apart
• Poles located more than 2.5 times the building
  distance

How does LEED apply to site lighting?

• Sustainability (1 point)
• Credit 8 Light Pollution (full cutoff)
• Energy and Atmosphere (1 point)
• Credit 1 Optimizing Energy Performance
  (overall reduction)
• Innovation Design (1 point)
• Credits for Reduced Mercury Content (Natural
  White Lamps)

14

SS Credit 8 Light Pollution Reduction 1 Point
Intent Minimize light trespass from the
building and site, reduce sky-glow to increase
night sky access, improve nighttime visibility
through glare reduction, and reduce development
impact on nocturnal environments. Requirements
FOR INTERIOR LIGHTING The angle of maximum
candela from each interior luminaire as located
in the building shall intersect opaque building
interior surfaces and not exit out through the
windows. OR All non-emergency interior
lighting shall be automatically controlled to
turn off during non-business hours. Provide
manual override capability for after hours use.
AND FOR EXTERIOR LIGHTING Only light areas as
required for safety and comfort. Do not exceed
80 of the lighting power densities for exterior
areas and 50 for building facades and landscape
features as defined in ASHRAE/IESNA Standard
90.1-2004, Exterior Lighting Section, without
amendments. All projects shall be classified
under one of the following zones, as defined in
IESNA RP-33, and shall follow all of the
requirements for that specific zone LZ3
Medium (Commercial/Industrial, High-Density
Residential) Design exterior lighting so that
all site and building mounted luminaries produce
a maximum initial luminance value no greater than
0.20 horizontal and vertical foot-candles at the
site boundary and no greater than 0.01 horizontal
foot-candles 15 feet beyond the site. Document
that no more than 5 of the total initial
designed fixture lumens are emitted at an angle
of 90 degrees or higher from nadir (straight
down). For site boundaries that abut public
rights-of-way, light trespass requirements may be
met relative to the curb line instead of the site
boundary. LZ4 High (Major City Centers,
Entertainment Districts) Design exterior
lighting so that all site and building mounted
luminaries produce a maximum initial luminance
value no greater than 0.60 horizontal and
vertical foot-candles at the site boundary and no
greater than 0.01 horizontal foot-candles 15 feet
beyond the site. Document that no more than 10
of the total initial designed site lumens are
emitted at an angle of 90 degrees or higher from
nadir (straight down). For site boundaries that
abut public rights-of-way, light trespass
requirements may be met relative to the curb line
instead of the site boundary. LEED for New
Construction Version 2.2 October 2005

Exterior Lighting Densities (ASHRAE/IESNA
Standard 90.1-2004)   The total exterior lighting
power allowance for all exterior building
applications is the sum of the individual
lighting power densities permitted in Table 9.4.5
for these applications plus an additional
unrestricted allowance of 5 of that sum
Trade-offs are allowed only among exterior
lighting applications listed in Tradable
Surfaces section  Lighting used for the
following exterior applications is exempt when
equipped with a control device independent of the
control of the nonexempt lighting  specialized
signal, directional, and marker lighting
associated with transportation  lighting that
is integral to advertising signage or directional
signage  lighting that is integral to equipment
or instrumentation and is installed by its
manufacturer  lighting for theatrical purposes,
including performance, stage, film, and video
production  lighting for athletic playing
areas  temporary lighting  lighting for
industrial production, material handling,
transportation sites, and associated storage
areas  theme elements in theme/amusement parks
 lighting used to highlight features of public
monuments and registered historic landmark
structures or buildings.

Closing Remarks
Many changes in our industry new products
technologies, more rebate opportunities,
attention to quality lighting, etc.
It's easy to come up with new ideas the hard
part is letting go of what worked for you two
years ago..." - Roger von Oech
