One energy performance requirement for mixed fuel and all-electric
“Fuel-neutral” ordinances require buildings to comply with greater energy performance levels regardless of building power source—electricity and natural gas OR electricity only
- Easy to communicate and understand
- No external documents or calculations
- Likely fewer GHG emission reductions

Install efficiency, renewable, or electrification measures in existing building if not included in project scope
Require upgrades beyond work triggered by Title 24 code. Examples include: add attic insulation to vented attic spaces, or apply air sealing to accessible areas
- Impact on existing homes with greatest savings potential
- Often politically challenging to adopt requirements for existing homes

Require photovoltaic (PV) System on all single family residential additions
Examples include: install a solar PV system according to Title 24, Part 6 requirements for new construction, or based on floor area or projected annual electrical usage
- Minimum PV system capacity depending on feasibility
- Min size requirement may encourage installation of more capacity to meet entire load
- Tax credit
- Requires external documents and/or calculations
- Can be a significant incremental cost
- Challenges regarding compatibility with existing systems

Photovoltaic (PV) System on existing high-rise multifamily or nonresidential projects
For example, Specify minimum system capacity based on filling specified percentage of rooftop area
- Stand-alone or combine with energy efficiency measures for greater savings
- PV is cost-effective under most major project scenarios
- Tax credit
- Can be a considerable incremental cost
- Highly variable investment requirements
- Physical constraints on rooftop
- Sizing may not be optimal for occupancies with different load profiles

Require upgrade by “Date-Certain”, a single date or phased schedule) specified in the policy OR at tenant change, or other specified interval
Establish defined dates or events to trigger requirements for energy efficiency improvements that would otherwise not be undertaken unless existing buildings are altered or undergo tenant improvement
- Likely to cover all properties within scope
- No impact on unrelated real estate or financial transactions
- Distribution of benefits to more renters
- Rental properties often have significant potential
- Requires internal jurisdiction resources to implement policy and maintain records
- Potential for owner resistance to investment when tenant reaps utility benefits

Install either heat pump water heater (HPWH) or solar thermal
Decrease water heating-related carbon emissions due to natural gas or propane fueled water heaters by requiring electric heat pumps or increasing the solar thermal contribution
- Single measure may be more palatable
- Significantly reduces or eliminates emissions from significant source
- No savings from avoided gas infrastructure
- Some projects will not exceed state code
