Wrap-up and next steps 11:45 – 12:00 CA Utilities 2011 Title 24 Stakeholder Meeting for Proposed Code Changes 10/20/2010
3 CALIFORNIA STATEWIDE UTILITIES CODES AND STANDARDS PROGRAM Residential Lighting Base Code Change Proposals ● Require at least one high efficacy luminaire in all bathrooms. ● This fixture is not required to be on an occupancy sensor. ● Not changing: ● High efficacy fixtures must be switched separately from low efficacy fixtures, as required in 150(k) ● Allow incandescent fixtures including bath bars (vanity lighting) on dimmers or manual-on occupancy sensors ● Possible that GU-24 bath bars will become typical in production homes without code change… CA Utilities 2011 Title 24 Stakeholder Meeting for Proposed Code Changes 10/29/2010
4 CALIFORNIA STATEWIDE UTILITIES CODES AND STANDARDS PROGRAM Residential Lighting Base Code Change Proposals Require high efficacy in all Garages, Laundry Rooms, Closets and ● Utility Rooms Eliminate occupant sensor exception for Garages, Laundry Rooms, ● Closets and Utility Rooms “ EXCEPTION 1 to Section 150(k)10: Permanently installed low efficacy luminaires ● shall be allowed provided that they are controlled by a manual-on occupant sensor certified to comply with the applicable requirements of Section 119.” Maintain additional incandescent allowance for kitchens ● If all luminaires in Garages, Laundry Rooms, Closets and Utility Rooms ● are controlled by manual-on occupant sensors (in addition to being high-efficacy) Allows additional 50 watts for dwellings less than or equal to 2500 square feet or 100 ● watts for dwelling units larger than 2500 square feet CA Utilities 2011 Title 24 Stakeholder Meeting for Proposed Code Changes 10/29/2010
5 CALIFORNIA STATEWIDE UTILITIES CODES AND STANDARDS PROGRAM Residential Lighting Base Code Change Proposals ● A voluntary energy credit for installing all-high er -efficacy lighting. ● High er -efficacy defined in the same manner as “high efficacy” ● High efficacy is defined as 30-50 lm/W depending on wattage ● Higher efficacy would be 70 lm/W—just below current LED performance ● Energy credit in the form of X BTU/sf/yr ● Can be traded for other energy systems CA Utilities 2011 Title 24 Stakeholder Meeting for Proposed Code Changes 10/29/2010
6 CALIFORNIA STATEWIDE UTILITIES CODES AND STANDARDS PROGRAM Residential Lighting Reach Code Change Proposals ● Require all-high er -efficacy for any hardwired lighting ● Mandatory requirement ● Structure of the Reach Code is not yet fully defined ● Same criteria as base code to define high er -efficacy CA Utilities 2011 Title 24 Stakeholder Meeting for Proposed Code Changes 10/29/2010
7 CALIFORNIA STATEWIDE UTILITIES CODES AND STANDARDS PROGRAM Residential Lighting All-Higher-Efficacy Lighting Credit ● Installed Lighting in New Residential Construction Source: 2010 California New Home Energy Survey, funded by a PIER Building Energy Research Grant , and by the Statewide Utility Codes and Standards Program. CA Utilities 2011 Title 24 Stakeholder Meeting for Proposed Code Changes 10/29/2010
8 CALIFORNIA STATEWIDE UTILITIES CODES AND STANDARDS PROGRAM Residential Lighting All-Higher-Efficacy Lighting Credit ● Luminaire Type Transformation Typical New Construction All-Higher-Efficacy Model Portable Lighting no change Linear Fluorescent no change LED no change CFL LED equivalent Incandescent / Halogen LED equivalent ● Lamp transformations based on currently-available products ● 60W incandescent → 11W LED ● 26W CFL → 11W LED, etc. CA Utilities 2011 Title 24 Stakeholder Meeting for Proposed Code Changes 10/29/2010
9 CALIFORNIA STATEWIDE UTILITIES CODES AND STANDARDS PROGRAM Residential Lighting All-Higher-Efficacy Lighting Credit ● Reduction in Average Installed Lighting Power Average 58% reduction in installed lighting power Source: 2010 California New Home Energy Survey, funded by a PIER Building Energy Research Grant , and by the Statewide Utility Codes and Standards Program. CA Utilities 2011 Title 24 Stakeholder Meeting for Proposed Code Changes 10/29/2010
10 CALIFORNIA STATEWIDE UTILITIES CODES AND STANDARDS PROGRAM Residential Lighting All-Higher-Efficacy Lighting Credit To calculate the energy impact, we used average hours of use for ● each room type, based on CFL lamps in Upstream Lighting Study Room Type Daily Hours of Use Bathroom 1.4 Bedroom 1.7 Dining 1.9 Hall 1.2 Kitchen 2.5 Living 2.3 Office 1.6 Other 1.4 For other room types, we assigned hours of use conservatively (i.e. ● low values) based on this list. Source: 2010 Upstream Lighting Program Final Evaluation Report, prepared for the California Public Utilities Commission, Energy Division. Hours of use data is based on installed and retrofitted CFLs in existing homes CA Utilities 2011 Title 24 Stakeholder Meeting for Proposed Code Changes 10/29/2010
11 CALIFORNIA STATEWIDE UTILITIES CODES AND STANDARDS PROGRAM Residential Lighting All-Higher-Efficacy Lighting Credit ● Reduction in Annual Lighting Energy Use Average 52% reduction ● Includes only the lighting savings—no cooling savings or heating penalty CA Utilities 2011 Title 24 Stakeholder Meeting for Proposed Code Changes 10/29/2010
12 CALIFORNIA STATEWIDE UTILITIES CODES AND STANDARDS PROGRAM Residential Lighting All-Higher-Efficacy Lighting Credit ● Energy Savings by Unit Size ● Credit should be no more than 0.45 kWh/year/sf ● 2700 sf house ● Saves 1300 kWh/yr ● Measure savings TDV $4300 ● Final number will include heating and cooling effects CA Utilities 2011 Title 24 Stakeholder Meeting for Proposed Code Changes 10/29/2010
13 CALIFORNIA STATEWIDE UTILITIES CODES AND STANDARDS PROGRAM Residential Lighting All-Higher-Efficacy Lighting Credit ● Implementation in Base Code ● Hard cap—1500 kWh/yr? ● Flat value—1000 kWh/yr? ● Compliance software would be modified to apply this credit to the whole house budget ● Credit is only available in houses that have an air conditioner CA Utilities 2011 Title 24 Stakeholder Meeting for Proposed Code Changes 10/29/2010
14 CALIFORNIA STATEWIDE UTILITIES CODES AND STANDARDS PROGRAM Residential Lighting Costs for All-Higher-Efficacy ● Costs from Home Depot ● Incandescent housing and trim: $15 + lamp ● CFL housing and trim: $43 + lamp ● LED housing and light engine with integral trim: $60 ● Does the cost data support the possibility of making Higher-Efficacy mandatory in Base Code? CA Utilities 2011 Title 24 Stakeholder Meeting for Proposed Code Changes 10/29/2010
15 CALIFORNIA STATEWIDE UTILITIES CODES AND STANDARDS PROGRAM Residential Lighting Needed Standards for Self-Ballasted Lamps ● Must ensure adequate light output and life during elevated temperature operation ● Testing to date: ● Maxlite found that only 9W self-ballasted don’t exceed rated temp in recessed cans ● LRC / EPA accelerated life test ● PNNL test, half of ES reflector CFLs reached their rated life in an elevated temperature test in ICAT fixtures ● PNNL also found that heat build-up took at least 20 minutes ● LRC’s Specifier Report from 2005 showed that many CFLs are available with rated maximum ambient air temperatures higher than 55°C CA Utilities 2011 Title 24 Stakeholder Meeting for Proposed Code Changes 10/29/2010
16 CALIFORNIA STATEWIDE UTILITIES CODES AND STANDARDS PROGRAM Residential Lighting Needed Standards for Self-Ballasted Lamps ● Applicable standards ● Energy Star currently requires CFLs to be rated for use in 50°C ambient air ● CFLs are available with a 90°C maximum ballast case temp. For safety reasons, 90°C is the highest ballast case temperature limit allowed under UL 1598 ● DOE’s Elevated Temperature Life Test procedure ● Which standards must be in place to ensure that self- ballasted lamps will perform adequately in both new construction and retrofit situations in enclosed and/or recessed fixtures? CA Utilities 2011 Title 24 Stakeholder Meeting for Proposed Code Changes 10/29/2010
17 CALIFORNIA STATEWIDE UTILITIES CODES AND STANDARDS PROGRAM Residential Lighting Data Requests—by 11/12/2010 ● Please provide cost information—will LEDs still be more expensive than CFL by 2013? Is this a “giveaway”? ● Please provide current cost data, and projected cost data if possible ● Please provide additional cost data for higher-efficacy sources ● LED ● Linear Fluorescent ● Please provide any other available information on elevated temperature testing or standards ● HMG white paper will be circulated after this call CA Utilities 2011 Title 24 Stakeholder Meeting for Proposed Code Changes 10/29/2010
