Lighting and Sustainable Design

1
Lighting and Sustainable Design A Consciousness
for The Future
Annual Conference 2002
2
Sustainable Design Getting the Green Light

• Sustainable design meets the qualitative needs
  of the visual environment with the least impact
  on the physical environment
• I A L D / Sustainable Design Committee
• November 2001

3
IALD SDC Goals

• ..to create an expanded awareness and
  consciousness of important global design issues
  in lighting, through educational seminars,
  articles and policy statements worldwide
• Topics include
• Energy Efficiency
• Daylighting Integration
• Lighting Control Programs
• Light Pollution and Light Trespass
• Visual Performance and Human Factors
• Durability and Maintainability of Lighting
  Systems
• Eco-Friendly Products and Processes/ recognition
  to manufacturers

Ways in which designers create awareness and
promote good lighting practice

• Good lighting design is value added for reasons
  of
• Aesthetics
• Professional service to the project
• Helps people and aids visibility
• Environmental impact
• Economics

5

• What is the best strategy to create an awareness
• off the value of sustainable issues through
  better
• design?
• R.O.I / Return on Investment
• Lighting is a technology that can actually
  provide a payback on an initial investment over
  time !

6
Cost Associated with Lighting Programs

• Initial Cost
• Equipment Installation / Labor
• Lighting Controls
• Daylight Design
• Aesthetics / The design of the luminaire and the
  Illumination
• Feesliability and the cost of doing it right the
  1st time
• Life Cycle Costs
• Energy / Maintenance
• People / the human factor
• Environmental factors
• lets take a look at a few of these issues

7
Equipment Cost Factors

• Price, performance, availability, durability,
  installation time, eco-friendly manufacturing
  considerations
• Establish budgets early / do value engineering
  up front
• Have the involvement early in the design, of the
  project owner / operator
• Provide clear and concise specifications
• Manage the design and control the specification
• Follow the IALD / LIRC Guidelines for Lighting
  Specification Integrity
• Case study..conversation

8
Lighting Control System Benefits

• Save energy
• Cut maintenance costs by increasing lamp life
• Integrate daylight and electric light with
  control systems / photocells
• Increase productivity in offices with
  personalized control in private areas
• Attract attention in retail
• Create ambience in restaurants
• Improve nighttime security
• Reduction of sky pollution
• Case study..conversation

9
Daylight Design

• Integration of architecture, daylight and
  electric lighting systems to improve mood,
  performance and reduce operations costs

Scale model study
Glare index
Computer model study

Illumination Aesthetics

• Luminaire selection considerations
• Creative lighting techniques brings award winning
  value added to any project ..

11
Energy and Maintenance

• Life cycle cost analysis could demonstrate a
  substantial return on investment when specifying
  an energy efficient system of lamps, ballasts,
  high performance luminaires and a lighting system
  that is designed with future maintenance in mind

12
The Human Factor

• Visibility and customer perception in retail
  environments to increase sales
• Improved speed and accuracy of workers in
  critical inspection areas
• Increased commerce in downtown districts
• Improved nighttime perception of city image
• Reduction in crime after dark
• Reduced liability risk from accidents
• Office lighting and productivity

13
Office Productivity

• Research is underway to prove what we
  instinctively already know
• The quality of illumination affects mood,
  attitude, performance, health and productivity.
• Design using the qualities of illumination
• Illuminance and luminance
• Color / Color Kelvin and CRI
• Brightness / measured, perceived and visual
  comfort
• Illuminance contrast / Uniformity
• Movement and patterns

14
The cot of better productivity

• Lets do the math
• Cost of an office lighting system 2.50 -
  6.00 sq/ft
• Cost of salaries / typical office 140.00 -
  160.00 sq/ft
• Cost to improve lighting quality 1.00 -
  3.00 sq/ft
• ?? what IF using proven lighting techniques
  could
• improve productivity by as little as 2 percent
  ??

15
Environmental Factors

• Light Pollution and
• Quality
• Were you aware that
• Billions of are wasted each year from light
  directed up into the sky
• White light can be more efficient than yellow
  light for nighttime visibility
• Visit the Dark Sky Association web site at
  www.darksky.org
• And
• Consider using manufacturers that actively use
  eco-friendly processes

16
The value of good designa few questions
