1 1 Stakeholder Meeting 3 California Statewide Utility Codes and Standards Program Heschong Mahone Group, Inc. Integrated Lighting Concepts, Inc. February 24, 2011

2 Summary of Code Change Proposals 2 Reduce LPD for Floor and Wall Display and Ornamental Lighting under Tailored Compliance (Table 146G T ) Significantly reduce space types allowed under the Tailored compliance. (Table 146G T ) Mandate use of comprehensive lighting controls as a prerequisite to using the Tailored Lighting method of Title 24 compliance under the 2013 standards.

3 Summary of Code Change Proposals 3 Re-alignment of mounting height adjustment factor (Table 146H T ) Reduce allowed LPD for very valuable display (Section 146(c) 3.B iv. )

4 Energy Savings Results 4 Energy Savings & Cost Effectiveness associated with: CMH Lamps for Accent and Display LED Lamps and systems and Candelabra Low Wattage Halogen for display and decorative (specialty lighting) CFL, T5, T5/HO, High and Wattage CMH in advanced models ( TBD analysis process in works)

5 Costs Incremental costs related to CMH Display Luminaires and Lamps Equipment Luminaire/lamp costs 20% less than last cycle Self ballasted CMH available this cycle Incremental cost still higher than ideal Labor Little or no impact (except related to maintenance) Maintenance Lower to significantly lower frequency of Higher cost associated with repairs 5

6 Cost Effectiveness Results 6 7 Year Cost Recovery of CMH Lamps & Luminaires for Retail Store Applications All But 20W CMH are Cost Effective 20W & 39W CMH Compared with HIR 70W compared with 250W Quartz Halogen

7 Cost Effectiveness Results 7 15 Year Cost Recovery CMH Lamps & Luminaires for Retail Store Applications 20W CMH are Cost Effective 20W CMH Luminaire and CMH Self Ballast Lamp Compared with 55W HIR lamp

8 Costs Incremental costs related to Higher Efficacy Ornamental & Decorative Lighting Equipment Luminaire costs are low for IR halogen, medium for CFL and high for LED Labor Little or no impact with installation, most in fabrication of luminaires Maintenance Lower to significantly lower as well as much longer lamp life 8

15 Tailored Lighting Compliance in Retail Spaces Mandate use of comprehensive lighting controls as a prerequisite Revise/add to SECTION 146 ( C ) 3. Prescriptive Requirements for Indoor Lighting as follows on next slide 15

16 16 SECTION 146 PRESCRIPTIVE REQUIREMENTS FOR INDOOR LIGHTING 3. Tailored Method. The Tailored Method shall be used only on projects with primary function areas that do not use the Area Category Method. As a prerequisite to use of the Tailored Method Compliance all lighting within the tailored spaces shall be controlled with an EMS (Energy Management System) using separate control for floor and wall display, casework and specialty lighting and Ornamental Special effects lighting. Control requirements for the Tailored Compliance are found in Section. TBD

17 Re-alignment of mounting height adjustment factor 17 (Table 146H T ) (Table 146H T ) Luminaire above finished floor Floor Display Multiplier Wall Display Multiplier or less > > 16 Feet > 20 Feet

18 Reduce allowed LPD for very valuable display [Section 146(c) 3.-B] (08) (13) 18 iv. In retail merchandise sales, museum, and religious worship, the smallest of the following separate lighting power for display cases presenting very valuable display items is permitted: a. Product of the area of the primary function and watt per square foot; b. Product of the area of the display case and watts per square foot, or c. Actual power of lighting for very valuable displays.

19 Space types using Area Compliance Title proposed LPD targets as aggressive as Washington 2010 and ASHRE/IES BIG BOX MODEL - A HIGH ATRIUM MODEL - B Base LPD: 1.2 W / SF (allows for 50 fc maintained general lighting plus some minimal layering for select higher illumination of features) Base LPD: 1.2W/SF Adder *7 LPD: 0.3 W / SF (1.5W max allows for 50 fc maintained general lighting plus layering for select higher illumination of walls and features)

20 Space types using Tailored Compliance 20 Model C Model D Model E Model F Model G Title LPD under 4 W/SF for five models Four of five models under 3 W/SF using advance lighting technologies Three of five models might use less aggressive technologies and still comply Title proposed lower LPD targets as aggressive as Washington 2010 and ASHRE/IES
