ZNE GOALS Background

Big Bold Goals- Adopted 2007-08 by Energy, Utilities Commissions

§ All new residential construction in California will be zero net energy by 2020 § All new commercial construction in California will be zero net energy by 2030 § 50% of existing commercial buildings will be retrofit to ZNE by 2030

CA Policy Support for ZNE

2008 Energy Efficiency Strategic Plan:

“New construction will reach “zero net energy” (ZNE) performance (including clean, onsite distributed generation) for all new single and multi-family homes by 2020” “New [commercial] construction will increasingly embrace zero net energy performance (including clean, distributed generation), reaching 100% penetration of new starts in 2030.”

2013 Integrated Energy Policy Report (IEPR):

“To ensure success in meeting the zero-net-energy goals as they are currently outlined include adopting triennial building standards updates that increase the efficiency of new buildings by 20 to 30 percent in each update…and including a voluntary energy tier for zero-net-energy in the California Green Building Standards Code.”

Executive Order B-18-12 (Green Building Action

Plan): All new State buildings and major renovations beginning design after 2025 be constructed as Zero Net Energy. Interim target for 50% of new facilities beginning design after 2020 to be Zero Net Energy. State agencies effort toward achieving Zero Net Energy for 50% of the square footage of existing state-owned building area by 2025.  

First Update to AB32 Scoping Plan (May 2014):

“ARB is committed to building upon the recent policies and goals adopted by the CPUC and CEC and supporting the development of statewide programs, such that all new residential and commercial buildings are zero net energy by 2020 and 2030, respectively.” “The role and functions of utilities may need to evolve as California increasingly shifts toward more renewable and distributed energy integration.”

ZNE Code Building “A ZNE Code Building is one where net of the 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 California Energy Commission’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. 6

California Standards

ZNE Code

Two Code Cycles to ZNE Ready Code

ü  Title 24 2016 –  Hi performance attics

•  Insulated roof deck •  Ducts in conditioned space •  Ductless HVAC

–  Hi R-value Walls –  All High Efficacy Light –  Tankless Water Heaters

ü  T-20 (Phase 1 & 2) –  Computers/Monitors –  Consumer Electronics –  Lighting –  Other Products

ü  Title 24 2019 –  Infiltration/Ventilation

•  Controlled supply ventilation •  Low VOC materials

–  QII –  Dual Path – Preemption

•  High eff. HVAC, DHW –  Compact Water Dist. –  Drain Water HR

ü  T-20 (Phase 3) –  Recirculation pumps –  Power factor –  Standby loads –  TV’s (large, motion

sensing)

DOE Standards and Test Procedures •  The development process typically takes about 3 years and the

period between final rule and the effective date is typically 3-5 years, thus 6-8 years total.

Period of greatest influence: ET/EE program “code-readiness” activities

Future Standard Impact (State, Federal, or Both)

ET

Collaboration with a progressive, agile LED lamp manufacturer / LED driver manufacturer to develop high quality, high performance dimming LEDs that fit in small form factor of specialty lamps such as MR16s and candelabra base lamps, and specialty fixtures such as bath bars (also specialty products such as string lights). Test customer acceptance.

2014 2015

State: Support adoption of Title 20 MR16 standards, and improve compliance options with Title 24 Res Ltng reqs

ET Ongoing testing of new LED products to assess performance gains and measure against pricing 2014 2015 State: Support for the propsoed T20

and T24 LED quality standards

ETProject to test LED compatibility with dimmers; collaborate with NEMA to test the appropriateness of NEMA SSL 7A and eventually NEMA SSL7B

2015 2016

State: Political support for the 2018 45 lpw standards by ensuring consumer satisfaction and high performing systems

ET Consumer preference study to identify lighting characteristics that are most important to consumers in real world settings. 2015 2015 State: Support for the propsoed T20

and T24 LED quality standards

WE&T

A retailer-based education program could work with lighting sales staff of major big box chains to educate them on the key points around LED performance (especially key factors for incandescent equivalency), to help ensure consumers are satisfied with their LED purchases. Training would include compatibility with dimmers and other controls.

2015 2016

State: Political support for the 2018 45 lpw standards by ensuring consumer satisfaction and high performing systems

WE&T

Training for builders on compliance with 2016 All High Efficacy code requirements to increase consumer satisfaction, including compatibility with dimmers and controls.

2016 2017

State: Political support for the 2018 45 lpw standards by ensuring consumer satisfaction and high performing systems, also improve compliance with Title 24 standards

EE

IOU EE programs are already providing residential incentives for high quality LED lamps that meet the CEC Spec; however, rebate allocations have been inconsistent and have been put on hold at least once since launching, and per lamp rebate amounts have been steadily declining. Rebates structured to ensure that rebated (high quality) products have sale prices that are less than or equal to the sale prices of non-rebated (non-high quality) products.

2014 2018

State: Political support for the 2018 45 lpw standards by ensuring consumer satisfaction and high performing systems

EE

EE programs increased consumer outreach and educational materials to accompany rebate offers. In store materials can help point customers towards the appropriate products with the characteristics they're looking for. Web/phone apps to educate customers and direct them to participating stores and quality products.
