3 COURSE DESCRIPTION This session goes in-depth on commissioning of facility lighting and lighting control systems. This presentation lays the foundation for commissioning lighting systems in the design phase. Part 2 of this presentation focuses on the construction phase. This presentation describes impacts of lighting design review and commissioning. The presentation uses industry standards and two case studies to discuss early lighting design involvement, along with the CxA's role in design review according to current IES lighting Cx guidelines; energy implications of early lighting design decisions; a CxA s OPR and BOD review methodology for lighting; and a CxA s design review methodology for lighting.

4 LEARNING OBJECTIVES At the end of this session, participants will be able to: 1. Learn how to identify basic lighting issues with other professional disciplines involved the building design review and submittal process 2. Participate with design team in development of integrated, phased approaches and activities for daylighting and lighting commissioning 3. Describe and recommend lighting system commissioning and daylighting system commissioning methods, phases, and testing opportunities to owners and design teams 4. Identify red flags in lighting system design and daylighting system design

5 AGENDA Come with me, and you ll see, a world of pure illumination 1. About the Presenters 2. Importance Lighting Design Review 3. CxA s & Design Review 4. Energy & Operability 5. A CxA s OPR & BOD Review 6. A CxA s Design Review 7. Summary So much time and so little to see Wait a minute. Strike that. Reverse It.

6 ABOUT YOUR PRESENTERS James Donson, PE, LC BSME Cal Poly Pomona, 2008 kw s Lighting Expert Diverse Project Load Com &Ind.

7 EARLY LIGHTING DESIGN INVOLVEMENT It s important for a CxA to be involved early Industry is trending toward greater complexity Advanced Lighting Controls New Lighting Technologies Many fundamental lighting design decisions are made early in the design process Commercial Building End Uses (EERE, 10/2008) Energy Efficiency Trends in Residential & Commercial Buildings

8 A CXA S ROLE IN LIGHTING DESIGN A Guide Exists IESNA DG The IESNA is the lighting equivalent of ASHRAE Illuminating Engineering Society of North America DG 29-11: excellent overview of lighting Cx Target audience is CxAs and Lighting Designers Establishes possible requirements IESNA Design Guide (DG) 29-11

9 UNDERSTANDING LIGHTING FOR A CXA Architects, Engineers, or Lighting Designers Approaches will vary Technical characteristics influence Luminaire & Control Selection Operability Energy Consumption Comprehensive Knowledge Useful Lighting References include the IESNA Handbook and other reference texts

10 Predesign Design Construction OWNER S PROJECT REQUIREMENTS (OPR) REVIEW WITH REGARD TO LIGHTING DG documents all requirements Include big ideas with smart goals in the OPR Who are the occupants Describe tasks Minimizing Lamp Types Desired Level of Control Integration Goals If no OPR, CxA needs to be aware of pitfalls in subsequent reviews Table 1-1 from DG-29-11

11 Predesign Design Construction BASIS OF DESIGN (BOD) REVIEW FOR LIGHTING BOD informs the design as the OPR informs the BOD Identifying lighting issues now saves time and money later Review requirements include making sure the BOD meets the OPR BOD may not be achieved early in the predesign process Standards Maintenance Growth Appeal Application Future Cost Usability Interactive Effects Lighting Design Comfort Functionality Sustainability Many considerations feed into the lighting design Code Engaging Energy Use Laws

12 Predesign Design Construction BOD REVIEW FOR LIGHTING The 80% Lighting Selection One or Two fixtures make up 80% of the lighting in the space Technology is decided early and impacts OPR Operability & Comfort Energy Use Maintenance Sustainability Photometric fixture efficiency drives lighting energy use Lamps Scalloping Fixtures Light Rays 80% Lighting Selection Informs Overall Lighting Design & Lighting Terms Convey Ideas

13 Predesign Design Construction BOD REVIEW FOR LIGHTING The Design Reference The IESNA released the 10 th Edition of the Lighting Handbook in th edition is 13 years old 10 th edition is task-centric design Other design guides published by the IES and others may be appropriate

14 Predesign Design Construction REVIEWING THE LIGHTING DESIGN Design review is an excellent opportunity to add value Be team-based approach to design An opportunity to explore gaps in your own knowledge Review the fixture schedule at min Model Numbers Lamps & Technology Color Temperature CxA Tasks may overlap, making the design review a valuable use of time Energy Impacts O&M QC Sustainability

15 Predesign Design Construction REVIEWING THE LIGHTING DESIGN Don t Be Caught in a Dark Bathroom with Your Pants Down Occupancy sensors are in ASHRAE/IESNA 90.1 Finding discrepancies & improper applications Ultrasonic or Dual Technology Sensors in spaces with barriers Coverage pattern matches application & area Make sure sensors are detailed in the Specification ( ) Sensors come in many different shapes and sizes, each with specific performance criteria and application

16 Predesign Design Construction REVIEWING THE LIGHTING DESIGN Control Access, Functionality, & Usability Check that override switches for scheduling controls are located for easy use by cleaning staff Avoid whole-floor overrides Ensure that specification includes language documenting accessibility to controls & programming Lighting panels may be straight forward for vendors or electricians but represent a barrier to building managers

17 Predesign Design Construction REVIEWING THE LIGHTING DESIGN The Right Light without a Fight A couple of hours and a lighting model later, you can identify over-lit spaces LEDs increasingly appear in design documents and the CxA needs to know how to identify quality products Recommend LED fixtures for high or otherwise difficult to maintain areas Avoid TT5 (long CFL) lamps The luminous efficacy (lu/w) is low Maintenance is problematic The widening application of LEDs may push TT5 lamps out of the marketplace

18 SUMMARY So ends the design half of lighting commissioning We reviewed the following topics Importance of Lighting Cx Predesign Review (OPR & BOD) Design Review Criteria A basic check-list for predesign and design review follow at the end of these slides
