1. Getting the “Green Light”creating a consciousness for the future… Presented by: Stefan R Graf IALD LC IES

2. Lighting and sustainable design… “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. IALDSDC 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

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

5. What is the best way to create an awareness of the valueof sustainable lighting issues?? 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 Costs • Equipment & Installation / Labor • Lighting Controls • Daylight Design • Aesthetics / The design of the luminaire and the Illumination • 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. Initialco$tfactors • Equipment price, performance, availability, durability, installation time, eco-friendly manufacturing considerations • Have the involvement early in the design, of the project owner / operator • Establish budgets early and do “value engineering” up front • Provide clear and concise specifications Follow the IALD / LIRC Guidelines for Lighting Specification Integrity • Manage the design and control the specification • Provide owner/user maintenance manual and training

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 Case study.

9. Dimming control system, ROI 35,000 sq ft. World of Disney Store Dimming system payback period 2.5 years on 2500 quartz track lights.

10. Daylight Design Integration of architecture, daylight and electric lighting systems to improve worker performance, physiological health and reduce operations costs Scale model study Glare index Computer model study Annual illuminance curve

11. Daylighting design ROI Daimler Chrysler Technology Center Daylighting controls Integration. New design saves over $80,000 in construction costs and $60,000 per year in operations cost ! World of Disney / photocell and glazing design

12. The cost of lighting aesthetics • Luminaire selection considerations • Creative lighting techniques brings award winning value added to any project ….. Sky Garden / Sydney Australia Regent court Southfield mi Donner Office Southfield MI

13. Energy and Maintenance • Use life cycle cost analysis to demonstrate a substantial return on investment when specifying an energy efficient system of lamps, ballasts, high performance luminaires and a lighting system designed with future maintenance in mind Environmentally friendly lamp technology LED and Induction Lamps100,000 hr life

14. Thehuman factor • Visibility and customer perception in retail environments • 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 Downtown Houston Texas, events lighting for a weekend festival

15. Office Productivity • Research is underway to prove what we instinctively already know…… The quality of illumination affects our mood, attitude, performance, health and productivity…. Design begins using the qualities of light • Illuminance and luminance • Color / color Kelvin and CRI • Brightness / measured and perceived • Visual comfort / minimize glare • Illuminance contrast

16. The co$t 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 ?? Watch for new information on line from the Right Light Consortium at www.lightright.org

17. 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 is more efficient than yellow light for human nighttime visibility in some applications • Visit the Dark Sky Association web site at www.darksky.org • Consider using manufacturers that actively use eco-friendly processes View from the space shuttle

18. Future IES recommended practices for outdoor lighting will address Glare as the primary Factor over illuminance and uniformity, in evaluating outdoor lighting design Glare reduces visibility and increases energy consumption ETAL Committee / Evaluation of Task Adaptation luminance…will study how background luminance affects visibility Outdoor lighting must be designed as an integrated system of illumination Glare… an important factor affecting nighttime visibility

19. When should you consider using a professional lighting designer ? • When client expectations are important • If controlling costs is a benefit • In projects where life cycle costing or ROI is an important consideration • In projects where good ‘visual dynamics’ and visibility is essential • To limit risk and liability
