10/20/2010 CA Utilities 2011 Title 24 Stakeholder Meeting for Proposed Code Changes

Requirements for Retrofit Projects Agenda

• Review proposed language for lighting retrofit

requirements:

• Requiring compliance with Section 131 (a,b,c,d) (controls

requirements) for all retrofit projects (irrespective of rewiring), using wireless lighting controls for communication between the luminaire groups and the controllers.

• Requiring compliance with Section 146 (LPD requirements) for

retrofit projects at a lower threshold of lighting replaced (10% instead of 50%)

• Data Requests

Current Code Requirements

• Additions
• Covered in Section 149(a)
• Lighting must meet the same requirements as new

construction

• Definition of Alterations
• Covered in Section 149(b)1
• Replacement of parts of an existing luminaire,

including installing a new ballast or new lamps, without replacing the entire luminaire is not an alteration subject to the requirements of Section 149 (b) 1.

10/20/2010 CA Utilities 2011 Title 24 Stakeholder Meeting for Proposed Code Changes

Current Code Requirements

• Alterations (Covered in Section 149(b)1I)
• Lighting Power Density Requirements cut in at 50% replacement
• 1. Alterations that increase the connected lighting load, or

replace,remove and re-install more than a total of 50 percent or more

• f the luminaires in an enclosed space, shall meet the requirements of

Sections 130 and 146.

• Controls requirements cut in when new lighting exceeds 0.5

W/sf

• 4. Alterations that have less than 0.5 watts per square foot and

increase the existing lighting power density to 0.5 watts per square foot or greater shall meet the requirements of Sections ,119, 130, 131, 134, 143(c), and 146.

Current Code Requirements

• Alterations (Covered in Section 149(b)1I)
• Controls Requirements also cut in when certain

rewiring conditions are met

• 2. The following wiring alterations shall meet the requirements
• f Sections 119, 131, and 134.

– i. Where new or moved wiring is being installed to serve added

• r moved luminaires; or

– ii. Where conductor wiring from the panel or from a light switch to the luminaires is being replaced, or – iii. Where a lighting panel is installed or relocated.

New ASHRAE 90.1-2010

• 9.1.2 Lighting Alterations The alteration of lighting systems in any

building space or exterior area shall comply with the lighting power density (LPD) requirements of Section 9 applicable to that space or area and the automatic shutoff requirements of 9.4.1.1. Such alterations shall include all luminaires that are added, replaced or

• removed. This requirement shall also be met for alterations that

involve only the replacement of lamps plus ballasts. Alterations do not include routine maintenance or repair situations. Exception: Alterations that involve less than 10% of the connected lighting loads in a space or area need not comply with these requirements provided that such alterations do not increase the installed interior LPD.

Differences between T-24 and ASHRAE 90.1

• Title 24-2008
• Retrofit 50% of load

triggers LPD requirement

• Applies only when

luminaire is removed

• r replaced
• Lighting controls

requirements are not triggered unless circuiting moved or replaced

• ASHRAE 90.1-2010
• Retrofit 10% of load

triggers LPD + auto shut-off control

• Applies to all retrofits

(repaired or replaced)

• Also includes lamp +

ballast change-out

• Also requires auto-

shut-off controls

Summary of Code Change Proposals

• Amend Section 149(b)1:

NOTE: Replacement of parts of an existing luminaire, including installing a new ballast or new lamps or optical components, without replacing the ballast or housing of the entire luminaire is not an alteration subject to the requirements of Section 149 (b) 1.

• This would bring Title 24 in line with ASHRAE-IESNA

90.1 2010, but would impact lighting retrofit incentive programs due to the lowered baseline LPD.

Summary of Code Change Proposals

• Amend Section 149(b)1(I):
• 1. Alterations that increase the connected lighting load, or replace or alter,

remove and re-install more than a total of 510 percent or more of the luminaires in an enclosed space enclosed by ceiling-height partitions, shall meet the requirements of Sections 130, 131(d) and 146.

• 2. Luminaires that are replaced or altered shall meet the requirements of

Section 131(a,b, and c)

• [Retain existing 149(b)1(I)2 (req’ts on rewiring), for projects in which

the luminaires are not altered or replaced]

• [Remove 149(b)1(I)3 (subdivided spaces only required to meet

131(a,d). They will be required to meet a,b,c, and d]

• [Remove 149(b)1(I)4 (spaces that rise above 0.5W/sf must meet

131(a,b,c,d), since this is redundant]

Summary of Code Change Proposals

• Amending Section 149(b)1(I) would require controls

to be retrofitted in all lighting retrofit projects. The rationale for this is that:

• Controllable luminaires are now cost-effective, as established

by the Controllable Lighting CASE process

• Controllable luminaires can cost-effectively be connected by

low voltage control wires that allow them to be grouped for:

• Area controls under Section 131(a)
• Photocontrols under Section 131(c)
• These luminaire groups can be connected wirelessly to

switches and timeclocks (131(a,d))

• Luminaire groups can be wired to local dimming photocontrols

(131(c))

Data Requests

• Need cost data on wireless controls
• Cost to implement a local wireless wall switch for area controls (section

131(a))

• Cost to implement wireless connection to a circuit panel/timeclock for

shut-off controls (section 131(d))

• The cost to implement photocontrols should be no

different to a new construction project, because:

• Controllable Lighting will be required under 2011 code, and
• Therefore control wiring between fixtures will already be in place
• Fixtures can grouped for daylighting without added cost
• Photocell/photocontroller are simply retrofitted into the ceiling

Data Requests

• Need to understand the likely effect of new code

requirements on the rate of compliance for retrofit projects, and how much energy would be saved by this change:

• What % of lighting is typically replaced? (i.e., how many projects

fall in the 10-50% range?)

• What are typical existing vs. new LPDs?
• Are controls typically added? If so:
• What function do they perform?
• Are they wired or wireless?
• Typical cost-effectiveness of retrofit measures
