Lighting Alterations)

• Final Approval by the California Building Standards Commission: Nov-Dec 2015

• Effective Date:

January 1, 2017

• According to the CEC, Increased Efficiency from 2016 vs. 2013 Title 24:

 New buildings will save:

 Res: 345 GWh/yr electricity consumption (28%)*

 Non-res: 192 GWh/yr electricity consumption (5%)

 CO2e emissions reduced by 160,000 metric tons/yr

 Save 106.2 million gallons of water/year.

 Save over $4 billion with a cost of $1 billion over 30 years

* 50,000 homes at 6,900 kWh/home

AEE 2015 Annual Conference 5

2016 T-24 Highlights: Residential

1. High Performance Attics (HPA)

Roof deck insulation equivalent to R-13 insulation below deck and R-38 ceiling insulation. Insulation choices may include spray foam, batt, or blown-in, and SIP panels. Other options include:

 R-6 continuous insulation with radiant barrier

 Hybrid roofing systems combining insulation and higher roof reflectance

 Ducts in conditioned space (DCS)

 Ducts in sealed or unvented attics

2. High Performance Walls (HPW)

R19 cavity + R5 Continuous Insulation – U-Factor (Approx 0.051). Other options include:

 2x4 @ 16” OC, R15 + R-8 CI (0.051)

 2x6 @ 24” OC, R19 + R-5 CI (0.049)

 2x6 @ 24” OC, R21 + R-4 CI (0.048)

 Staggered studs with batt insulation or spray foam

 Structurally Insulated Panels (SIPs)

3. Instantaneous (Tankless) Water Heaters – basis with Energy Factor of 0.82

4. High Efficacy Lighting & Controls in kitchens & throughout the house (essentially eliminates incandescent by mandating pin-based lamps and expanding types of spaces req controls)

Nos 1 & 2 may be traded in most climate zones by installing a solar PV system capped at 2 kW

AEE 2015 Annual Conference 6

2016 T-24 Highlights: Non-Residential

Nonresidential Measures Mostly to Stay In-line With ASHRAE 90.1 National Standards:

* Controls and other measures related to Lighting Alterations/Retrofit was vociferously protested by certain labor/trade groups. CEC is holding further public review (Aug 12) and this section (Title 24, Part 6, Sections

141.0(b)2I, J, K, and L) will be folded into the current adoption without requiring a new rulemaking.

AEE 2015 Annual Conference 7

2016 Title-24 Nonresidential Standards:

Nonresidential Lighting Alternation Provisions Draft/Not Approved to Date

The Statewide IOU EC&S & EE Incentive programs teams worked closely with the CEC to update the 2013 provisions

Lighting Alteration Provisions Comparison

Measure

T-24 is triggered at what level of lighting modifications?

When new control is installed, acceptance tests required at how many luminaires?

Luminaire replacement and modifications can comply by installing auto-shut-off controls and area switches and by reducing power at what percentage?

2013

40 + greater than 10% of luminaires modified in a room

Code is ambiguous for lighting alterations and mod in place but manual requires acpt testing

Not by installed power reduction but if alteration or modification results in power in space being < 85% of area category LPD

2016

70 + greater than 2 luminaires modified in a room

20

Alterations 35% or reduce LPD to

< 85% of area category LPD

Are daylighting controls and dimming controls required?

Yes if installed LPD > 85% of area category LPD

No if installed LPD < 85% of area category LPD

Mod in place 35% or LPD < area category LPD

Lighting alterations

Yes if installed LPD > 85% of area category LPD

No if installed LPD < 85% of area category LPD

Modifications - No

• Streamlines & simplifies standard compared to 2013 standard

• Expected energy savings to the tune of 74 GWh/yr. Comparable to savings from high efficacy lighting in the residential new construction standards

AEE 2015 Annual Conference 8

2016 Title-24 Standards:

Nonresidential Lighting Alternation Provisions

The CEC withdrew its adoption of the provisions at its Business Meeting on

August 12. Most likely due to fierce opposition from labor groups (IBEW, NECA, and LMCC)* lobbying through the Governor’s office.

Support

• The IOUs, including SCE are generally supportive, although none provided any written comments

• EcologyAction, who works closely with SCE EE Program folks expressed support

• The city & county of San Francisco, Davis, & Stanford University expressed support

• Also in support are numerous small lighting installers

Oppose

• Besides Big Labor, LADWB and some lighting installers and consultants opposed the provisions

• Several lighting manufacturers opposed the provisions but would support them if their suggested changes are incorporated

*IBEW: International Brotherhood of Electrical Workers

NECA: National Electrical Contractors Association

LMCC: Labor Management Cooperation Committee

AEE 2015 Annual Conference 9

Title 20 Standards for Indoor Water Appliances

Very little opposition because of the Drought

Adopted by the CEC: August 12, 2015 by a vote of five to zero

Bathroom Faucets :

 1.5 gallons per minute flow rate (effective Sep 1, 2015)

 1.2 gallons per minute flow rate (effective Jul 1, 2016)

Shower Heads :

 2.0 gallons per minute maximum flow rate (effective Jul 1, 2016)

 1.8 gallons per minute maximum flow rate (effective Jul 1, 2018)

Current rules, established in 1994 at the federal level, allow a maximum flow of 2.5 gallons per minute from a shower head.

CEC: After a full turnover of shower head and faucet stocks by 2029, the regulations are expected to save 38 billion gallons of water, 20.2 billion cubic feet of natural gas and 1,322 gigawatt hours of electricity

(including embedded energy)

♫ Opportunity to incent Daylighting, Demand Response, and Dimming controls through 2019 (if Lighting Alteration provisions are approved as proposed)

♫: Opportunity X: Negative impact

11 AEE 2015 Annual Conference

Lynchpin of Future T-24 Standards: ZNE

Zero Net Energy : Residential by 2020 and Nonresidential by 2030

Current Official Definition: “

A ZNE Code Building is one where the net amount of energy produced by on-site renewable energy resources is equal to the value of the energy consumed annually by the building, at the level of a single ‘project’ seeking development entitlements and building code permits, measured using the CEC’s Time Dependent Valuation (TDV) metric. A ZNE Code Building meets an

Energy Use Intensity value designated in the Building Energy Efficiency Standards by building type and climate zone that reflect best practices for highly efficient buildings.

Governor Brown’s ZNE goals – focused on ZNE building code requirement by 2020 for newly constructed residential buildings – Get there in 3 code cycles (2013, 2016, 2019)!

Key element is TDV!

Time Dependent Valuation (TDV)

1.

Value of gas and electricity changes depending on the season and the time of day

2.

8,760 TDV multipliers for each hour of the year

3.

Favors measures that save energy during high demand periods

2016 Changes to Title 24 Residential Lighting Requirements

The residential lighting requirements in Title 24 are mandatory requirements and do not show up in the performance approach except as default values and thus is not able to be traded off. This has not changed in 2016.

The 2016 standards have been significantly simplified as there is no longer any calculation of lighting wattage, the requirements are simple

-- all lighting has to be high efficacy and if the light source is LED or is a lamp with a base that was traditionally incandescent (Edison screw base, halogen GU-11 or GU-5.6 etc) then the lamp must comply with Joint Appendix JA8 labelled “JA8-2016” – this essentially requires a high quality, LED source. The requirement for JA8 lamps are complex but that is something the manufacturers will figure out similar to the complex requirements for ENERGY STAR®, the consumer and the building official only need look for the JA8-2016 label on the lamp.
