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)
  • n dimmers or manual-on occupancy sensors
  • Possible that GU-24 bath bars will become typical in production homes

without code change…

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

Base Code Change Proposals

  • A voluntary energy credit for installing

all-higher-efficacy lighting.

  • Higher-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

Reach Code Change Proposals

  • Require all-higher-efficacy for any

hardwired lighting

  • Mandatory requirement
  • Structure of the Reach Code is not yet fully

defined

  • Same criteria as base code to define

higher-efficacy

All-Higher-Efficacy Lighting Credit

  • Luminaire Type Transformation
  • Lamp transformations based on currently-available

products

  • 60W incandescent → 11W LED
  • 26W CFL → 11W LED, etc.

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

All-Higher-Efficacy Lighting Credit

  • Reduction in Average Installed Lighting Power

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

  • For other room types, we assigned hours of use conservatively (i.e.

low values) based on this list.

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

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

All-Higher-Efficacy Lighting Credit

  • Reduction in Annual Lighting Energy Use
  • Includes only the lighting savings—no cooling savings or

heating penalty

Average 52% reduction

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

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

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
  • f making Higher-Efficacy mandatory in

Base Code?

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

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?

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
